EXCHANGE OF MESSAGE INCLUDING A FLIGHT SITUATION INDICATOR BETWEEN A USER EQUIPMENT CONNECTED TO THE DRONE AND A COMPONENT OF A NETWORK OF LANDWIRE COMMUNICATION SUBSCRIBER
CROSS REFERENCE TO RELATED ORDER
[0001] This application claims the benefit for Provisional Application No. US 62 / 501,054, entitled MANAGING DRONE-COUPLED USER EQUIPMENTS, deposited on May 3, 2017, attributed to the assignee of the same and expressly incorporated in its entirety as reference in this document.
BACKGROUND
1. Field of the Invention
[0002] The modalities refer to the exchange of a message including a message including a flight status indicator between user equipment coupled to the drone and a component of a terrestrial wireless subscriber network.
2. Description of the Related Art
[0003] User equipment (UEs), such as phones, tablet computers, desktop computers or laptop computers, are, in general, configured to connect to terrestrial wireless subscriber networks (eg., 3G, 4G, LTE 5G, Novo Rádio (NR) 5G, etc.) with the expectation that UEs will not be transported by air. For example, users are typically asked to place their respective UEs in airplane mode between takeoff and landing for commercial flights, which restricts the ability of the UEs to connect to wireless subscriber networks

2/67 terrestrial.
[0004] For most manned (or piloted) air vehicles, altitudes and / or cruising speeds make connections to terrestrial wireless communications networks impractical. For example, the commercial aircraft can reach cruising altitudes close to 12 km at speeds of 800 to 1000 km / h. Rather than relying on terrestrial wireless subscriber networks to support communications to / from manned aerial vehicles, such as commercial aircraft, most countries allocate a portion of Very High Frequency (VHF) radio spectrum to define an Air Band or an aircraft band that is dedicated to radio navigation communications and / or air traffic control communications.
[0005] Regulatory agencies are increasingly authorizing the deployment of unmanned aerial vehicles (UAVs), such as commercial drones. Commercial drones are being considered to provide a variety of services, such as package delivery, search and rescue, critical infrastructure monitoring, wildlife conservation, flying cameras, surveillance and so on. Commercial drones can operate at altitudes and speeds that are best suited for connections to terrestrial wireless subscriber networks. For example, in certain environments, commercial drones can operate at cruising altitudes close to 100 m at speeds up to or near 160 km / h. However, uplink signals from commercial drones that are in a flight state generally create more interference at terrestrial base stations in

SUMMARY
[0006] One modality is directed to a method of operating a user equipment attached to the drone (UE), which comprises determining whether the UE attached to the drone is engaged in a flight state, and transmitting a message to a network component of a terrestrial wireless subscriber network that indicates a determination result.
[0007] Another method is directed to a method of operating a network component of a terrestrial wireless subscriber network, which comprises receiving a message from a user equipment attached to the drone (UE) that indicates whether the UE attached to the drone is engaged in a flight state.

DETAILED DESCRIPTION
[0030] The disclosure modalities refer to various methodologies for managing user equipment coupled to the drone (UEs).
[0031] The aspects of the disclosure are revealed in the following description and related drawings directed to specific disclosure modalities. Alternative modalities can be designed without departing from the scope of the disclosure. In addition, well-known elements of the disclosure will not be described in detail or will be omitted in order not to obscure the relevant details of the disclosure.
[0032] The words example and / or example are used in this document to mean that they serve as an example, instance or illustration. Any modality described in this document as an example and / or example should not
Petition 870190108420, of 10/25/2019, p. 12/100
7/67 must necessarily be interpreted as preferential or advantageous over other modalities. Similarly, the term disclosure modalities does not require that all disclosure modalities include the feature, advantage or mode of operation discussed.
[0033] Additionally, many modalities are described in terms of sequences of actions to be performed by, for example, elements of a computing device. It will be recognized that various actions described in this document by specific circuits (for example, application-specific integrated circuits (ASICs)), program instructions that are executed by one or more processors or a combination of both. In addition, this sequence of actions described in this document can be considered as incorporated entirely into any form of computer-readable storage medium that has stored in it a corresponding set of computer instructions that, upon execution, would make a processor associate performs the functionality described in this document. Thus, the various aspects of the disclosure can be incorporated in several different ways, all of which have been contemplated to be within the scope of the claimed subject. In addition, for each of the modalities described in this document, the corresponding form of any such modalities can be described in this document as, for example, logic configured to carry out the described action.
[0034] A client device, called a user equipment (UE) in this document, can
Petition 870190108420, of 10/25/2019, p. 13/100
8/67 be mobile or stationary, and can communicate with a wired access network and / or a radio access network (RAN). As used herein, the term UE can be interchangeably referred to as an access terminal or AT, a wireless device, a subscriber device, a subscriber terminal, a subscriber station, a user terminal or UT, a mobile device, a mobile terminal, a mobile station and variations thereof. In one embodiment, the UEs can communicate with a main network through the RAN, and through the main network, the UEs can be connected to external networks, such as the Internet. Of course, other mechanisms for connecting to the main network and / or the Internet are also possible for UEs, such as over wired access networks, WiFi networks (for example, based on IEEE 802.11, etc.) and so on . UEs can be incorporated by any of several types of devices including, but not limited to, cell phones, personal digital assistants (PDAs), pagers, laptop computers, desktop computers, PC cards, compact flash devices , external or internal modems, cordless or corded phones, and so on. A communication link through which UEs can send signals to the RAN is called an uplink channel (for example, a reverse traffic channel, a reverse control channel, an access channel, etc.). A communication link through which the RAN can send signals to UEs is called a downlink or direct link channel (for example, a paging channel, a control channel, a broadcast channel, a traffic channel
Petition 870190108420, of 10/25/2019, p. 14/100
9/67 direct, etc.). A communication link through which UEs can send signals to other UEs is called a point-to-point channel (P2P) or device to device (D2D).
[0035] Figure 1 illustrates a high-level system architecture of a wireless communications system 100 according to a disclosure modality. The wireless communication system 100 contains UEs 1 ... N. For example, in Figure 1, UEs 1 ... 3 are illustrated as cell phones, UEs 1 ... 6 are illustrated as touch sensitive cell phones or smart phones, and UE N is illustrated as a computer desktop or PC type.
[0036] With reference to Figure 1, UEs 1 ... N are configured to communicate with an access network (for example, a RAN 120, an access point 125, etc.) along an interface or layer of physical communications, shown in Figure 1 as aerial interfaces 104, 106, 108 and / or a direct wired connection. Air interfaces 104 and 106 can support a specific cellular communications protocol (for example, CDMA, EVDO, eHRPD, GSM, EDGE, W-CDMA, LTE 4G, LTE 5G, Novo Rádio (NR) 5G, etc.), while overhead interface 108 can serve a wireless IP protocol (for example, IEEE 802.11). RAN 120 can include a plurality of access points that serve UEs along air interfaces, such as air interfaces 104 and 106. Access points on RAN 120 can be called access nodes or ANs, access points or APs , base stations or BSs, Nodes B, eNBs, gNBs and so on. These access points can be land access points (or ground stations), or access points
Petition 870190108420, of 10/25/2019, p. 15/100
10/67 satellite access. The RAN 120 can be configured to connect to a main network 140 that can perform a variety of functions, including bridge circuit switched calls (CS) between the UEs served by the RAN 120 and other UEs served by the RAN 120 or by a RAN completely different, and can also mediate an exchange of packet-switched data (PS) with external networks, such as Internet 175. As used in this document, RAN 120, main network 140 or a combination of them can be called a network of terrestrial wireless communication subscriber.
[0037] The Internet 175, in some examples, includes several routing agents and processing agents (not shown in Figure 1 for convenience). In Figure 1, the UE N is shown connecting directly to the Internet 175 (that is, separate from the main network 140, as in a WiFi Ethernet connection or 802.11 based network). Internet 175 can thereby function to connect packet-switched data communications between UEs 1.. . N through main network 140. Access point 125 is shown in Figure Ido also in Figure 1 which is separate from RAN 120. Access point 125 can be connected to the Internet 175 independent of main network 140 (for example, via optical communication system, such as FiOS, a cable modem, etc.). Air interface 108 can serve UE 5 or UE 6 over a local wireless network, such as IEEE 802.11 in one example. The UE N is shown as a desktop computer with a wired connection to the Internet 175, as a direct connection to a modem or router, which can correspond to itself
Petition 870190108420, of 10/25/2019, p. 16/100
11/67 access point 125 in an example (for example, for a WiFi router with both wired and wireless connectivity).
[0038] With reference to Figure 1, a server 170 is shown as connected to the Internet 175, the main network 140 or both. Server 170 can be implemented as a plurality of structurally separate servers, or, alternatively, can correspond to a single server. Server 170 can match any type of server, such as a web server (for example, hosting a web page), an application download server, or an application server that supports private communication services (or services), such as IP Multimedia Subsystem (IMS) service, such as Voice over Internet Protocol (VoIP) sessions, Push to Talk (PTT) sessions, group communication sessions, social networking services, etc.
[0039] With reference to Figure 1, UEs 1 ... 3 are depicted as part of a D2D network or a D2D 185 group, with UEs 1 and 3 being connected to RAN 120 through air interface 104. In one mode , UE 2 can also gain indirect access to RAN 120 through mediation by UEs 1 and / or 3, through which data 'jump' to / from UE 2 and one (or more) of UEs 1 and 3, that communicate with RAN 120 on behalf of UE 2.
[0040] Figure 2A illustrates an UE 200 according to a disclosure mode. The UE 200 includes one or more processors 205 (for example, one or more ASICs, one or more digital signal processors (DSPs), etc.) and a memory 210 (for example, RAM, ROM, EEPROM, flash cards
Petition 870190108420, of 10/25/2019, p. 17/100
12/67 or any memory common to computer platforms). The UE 200 also optionally includes one or more UI input components 215 (for example, a keyboard and mouse, a touchscreen, a microphone, one or more buttons, such as volume or power buttons, etc.) and one or more UI 220 output components (for example, speakers, a display screen, a vibrating device for vibrating the UE 200, etc.). In one example, the input components of UI 215 and the output components of UI 220 are optional because the UE 200 does not need to connect to a local user in all implementations. For example, if the UE 200 is implemented as a wireless communications component of a commercial drone, the UE 200 can be interconnected via remote connections instead of a local UI interface.
[0041] The UE 200 additionally includes a wired communications interface 225 and a wireless communications interface 230. In one example, the wired communications interface 225 may be optional (for example, commercial drones can be configured only for communications wireless) . In an example embodiment, if part of the UE 200, the wired communications interface 225 can be used to support local wired connections to peripheral devices (for example, a USB connection, a mini USB or lightning connection, a video headset, graphics ports such as serial, VGA, HDMI, DVI or DisplayPort, audio ports and so on) and / or to a wired access network (for example, via an Ethernet cable or another type) cable that can act as a bridge to the wired access network, such as HDMI vl.4 or
Petition 870190108420, of 10/25/2019, p. 18/100
Higher 13/67, etc.). In another example, wireless communication interface 230 includes one or more wireless transceivers for communication according to a local wireless communications protocol (for example, WLAN or WiFi, WiFi Direct, Bluetooth, etc.) and / or one or more wireless transceivers for communication with a cellular RAN (for example, through CDMA, W-CDMA, multiple time division access (TDMA), multiple frequency division access (FDMA), Orthogonal Frequency Division Multiplexing (OFDM), GSM, LTE, 4G, LTE 5G, NR 5G or other protocols that can be used in a terrestrial wireless subscriber network). The various components 205 to 230 of the UE 200 can communicate with each other via a 235 bus.
[0042] With reference to Figure 2A, the UE 200 can correspond to any type of UE, including, but not limited to, a smart phone, a laptop computer, a desktop computer, a tablet computer, a wearable device (for example, a pedometer, smart watch, etc.), a communications component of a larger device (for example, a cellular module integrated into a commercial drone), and so on. Three particular implementation examples of the UE 200 are depicted in Figure 2A, which are illustrated as the laptop computer 240, touch screen device 255 (for example, a smart phone, a tablet computer, etc.) and the terrestrial wireless subscriber network module (for example, cellular 290. The laptop computer 240 includes a display screen 245 and an area of UI 250 (for example,
Petition 870190108420, of 10/25/2019, p. 19/100
14/67 keyboard, touchpad, power button, etc.), and although not shown, the laptop computer type 240 can include various sizes as well as wired and / or wireless transceivers (for example, Ethernet card, WiFi, broadband card, etc.).
[0043] The 255 touchscreen device is configured with a 260 touchscreen display, 265, 270, 275 and 280 peripheral buttons (for example, the power control button, a volume control button or vibration, an airplane mode toggle button, etc.), and at least one 285 front panel button (for example, a Home button, etc.), among other components, as is known in the art. Although not shown explicitly as part of the 255 touchscreen device, the 255 touchscreen device may include one or more external antennas and / or one or more integrated antennas that are built into the external housing of the touchscreen device touch 255, including, but not limited to, WiFi antennas, cell antennas, satellite position system (SPS) antennas (for example, global positioning system (GPS) antennas) and so on.
[0044] The terrestrial wireless communication subscriber network module (for example, cellular) 290 is illustrated in Figure 2A as a circuit coupled to a radio antenna. The terrestrial wireless communication network module (for example, cellular) 290 can be integrated into a larger structure, such as a commercial drone, with the terrestrial wireless communication network module (for example, cellular) 290 that represents
Petition 870190108420, of 10/25/2019, p. 20/100
15/67 the UE (or communicative) component of the larger structure.
[0045] Figure 2B illustrates a 200B drone according to a disclosure mode. The 200B drone, which may be a commercial drone, which is licensed for at least some level of in-flight access to one or more terrestrial wireless subscriber networks, includes various flight hardware and flight control components (not shown) ), and is coupled to the UE 200. The UE 200 in Figure 2B can, by this means, be called alternatively a UE coupled to the drone. In one example, the UE 200 functions as a wireless communications component of drone 200B through which drone 200B can establish a connection with one or more terrestrial wireless subscriber networks to which in-flight access is authorized . In an additional example, the UE 200 on drone 200B can be integrated with the flight control components of drone 200B in at least one mode (for example, processor (or processors) 205 and / or memory 210 can support both communication features of the UE 200 as well as flight control).
[0046] Alternatively, the UE 200 can be physically attached to the drone 200B, but not communicatively. For example, a user can simply apply tape from the UE 200 to the drone 200B so that the UE 200 can record and transmit the video while the drone 200B is operated and controlled completely and independently from the UE 200. Therefore, depending on as the UE 200 and the drone 200B are configured, the UE 200 can be a UE coupled to the drone in a physical sense, in a communicative sense, or both.
Petition 870190108420, of 10/25/2019, p. 21/100
16/67
Additionally, a physical coupling between the UE 200 and the drone 200B can be semi-permanent (for example, the UE 200 is an integrated physical component installed on the drone 200B, such as the terrestrial wireless subscriber network module 290), or temporary (for example, a user ties or tapes UE 200 tape on drone 200B).
[0047] In addition, as will be described in more detail below, the UE 200 can be configured to access one or more terrestrial wireless subscriber networks while the drone 200B is in flight, or, alternatively, when the drone 200B it is not in flight (that is, grounded). In Figure 2B, two exemplary implementations of the 200B drone are shown. In particular, a 205B package delivery drone is shown carrying a 210B package, and a 215B surveillance drone is shown with a fixed camera 220B.
[0048] Figure 3 illustrates a network component 300 of a terrestrial wireless subscriber network according to a disclosure modality. Network component 300 can be a component of RAN 120 (for example, a base station, Node B, eNB, gNB, etc.), or alternatively, it can be a main network component of the wireless subscriber network terrestrial wire (for example, a Mobile Management Entity (MME) of a main LTE network, etc.). Network component 300 includes one or more processors 305 (for example, one or more ASICs, one or more DSPs, etc.) and memory 310 (for example, RAM, ROM, EEPROM, flash cards or any common platform memory computer). The network component 300 additionally includes an interface
Petition 870190108420, of 10/25/2019, p. 22/100
17/67 wired communications 325 and (optionally) a wireless communications interface 330. In one example, wireless communications interface 330 may be optional if network component 300 is implemented as a core network component, which is essentially a network server. The various components 305 to 330 of the network component 300 can communicate with each other via each other on the 335 bus. In an exemplary embodiment, the wired communications interface 325 can be used to connect to one or more components of return.
[0049] In another example, the wireless communications interface 330 (if it is part of network component 300) includes one or more wireless transceivers for communication according to a wireless communications protocol. The wireless communications protocol can be based on the configuration of network component 300. For example, if network component 300 corresponds to an access point that is implemented as a macrocell or small cell (for example, a femtocell, a picocell, etc.), the wireless communications interface 330 may include one or more wireless transceivers configured to implement a cellular protocol (for example, CDMA, W-CDMA, GSM, 3G, 4G, LTE 5G, NR 5G , etc.) . In another example, if network component 300 is implemented as a WiFi AP (for example, part of a WLAN, an Internet of Things (loT) network, etc.), the wireless communications interface 330 may include a or more wireless transceivers configured to implement a WiFi (or 802.11) protocol (for example, 802.11a, 802.11b, 802. llg, 802.11η,
Petition 870190108420, of 10/25/2019, p. 23/100
18/67
02.1lax, etc.).
[0050] Figure 4 illustrates a communication device 400 that includes structural components according to a disclosure modality. Communication device 400 can correspond to any of the communication devices noted above, including, but not limited to, UE 200 or network component 300, any component included in RAN 120, such as base stations, access points, eNBs, gNBs , BSCs or RNCs, any component of the main network 140, any component coupled to the Internet 175 (for example, server 170) and so on. Thus, communication device 400 can correspond to any electronic device that is configured to communicate with (or facilitate communication with) one or more other entities along the wireless communication system 100 of Figure 1.
[0051] With reference to Figure 4, the communication device 400 includes a set of transceiver circuits configured to receive and / or transmit information 405. In an example, if the communication device 400 corresponds to a wireless communication device ( e.g. UE 200), the transceiver circuitry configured to receive and / or transmit information 405 may include a wireless communications interface (e.g. LTE, NR 5G, Bluetooth, WiFi, WiFi Direct, Direct LTE, etc. .), such as a wireless transceiver and associated hardware (for example, an RF antenna, a MODEM, a modulator and / or demodulator, etc.). In another example, the transceiver circuitry configured to receive and / or transmit information 405
Petition 870190108420, of 10/25/2019, p. 24/100
19/67 can correspond to a wired communications interface (for example, a serial connection, a USB or Firewire connection, an Ethernet connection through which the Internet 175 can be accessed, etc.). Thus, if communication device 400 corresponds to some type of network-based server (for example, server 170), the transceiver circuitry configured to receive and / or transmit information 405 may correspond to an Ethernet card, in one example, which connects the network-based server to other communication entities via an Ethernet protocol. In an additional example, the transceiver circuitry configured to receive and / or transmit information 405 may include sensory or measurement hardware by which the communication device 400 can monitor its local environment (for example, an accelerometer, a temperature sensor , a light sensor, an antenna to monitor local RE signals, etc.). The transceiver circuitry configured to receive and / or transmit information 405 may also include software that, when executed, allows the associated hardware of the transceiver circuitry configured to receive and / or transmit information 405 to perform its function (or reception and / or transmission functions. However, the transceiver circuitry configured to receive and / or transmit information 405 does not correspond to the isolated software, and the transceiver circuitry configured to receive and / or transmit information 405 relies at least in part on structural hardware to achieve its functionality. In addition, the set of
Petition 870190108420, of 10/25/2019, p. 25/100
20/67 transceiver circuits configured to receive and / or transmit information 405 may be implied by a language other than receiving and transmitting, provided that the underlying function corresponds to a receiving and transmitting function. For example, functions such as obtaining, acquiring, retrieving, measuring, etc., can be performed by the transceiver circuitry configured to receive and / or transmit 405 information in certain contexts as being specific types of receiving functions. In another example, functions such as sending, delivering, transporting, forwarding, etc., can be performed by the set of transceiver circuits configured to receive and / or transmit 405 information in certain contexts as being specific types of transmission functions. Other functions that correspond to other types of receive and / or transmit functions can also be performed by the set of transceiver circuits configured to receive and / or transmit information 405.
[0052] With reference to Figure 4, the communication device 400 additionally includes at least one processor configured to process information 410. Exemplary implementations of the type of processing that can be performed by a processor configured to process information 410 include, but are not limited to a, realization, determination, establishment of connections, selections between different information options, performance of evaluations in relation to data, interaction with sensors coupled to the communication device 400 to perform measurement operations, conversion of information from one format to another format (per
Petition 870190108420, of 10/25/2019, p. 26/100
21/67 example, between different protocols, like.wmv para.avi, etc.) and so on. For example, the at least one processor configured to process information 410 may include a general purpose processor, DSP, ASIC, field programmable port arrangement (FPGA) or other programmable logic devices, discrete gate element or transistor logic , discrete hardware components or any combination thereof designed to perform the functions described in this document. A general purpose processor can be a microprocessor, but alternatively, the at least one processor configured to process information 410 can be any conventional processor, controller, microcontroller or state machine. A processor can also be implemented as a combination of computing devices (for example, a combination of a DSP and a microprocessor, a plurality of microprocessors, one or more microprocessors in conjunction with a DSP core or any other such configuration). The at least one processor configured to process information 410 may also include software that, when run, allows the associated hardware of at least one processor configured to process information 410 to perform its processing function (or functions). However, the at least one processor configured to process information 410 does not correspond to isolated software, and the at least one processor configured to process information 410 relies at least in part on structural hardware to achieve its functionality. In addition, at least one processor configured to process information 410 can

22/67 be implied by a different processing language, provided that the underlying function corresponds to a processing function. For example, functions such as evaluation, calculation, identification, etc., can perform at least one processor configured to process information 410 in certain contexts as being specific types of processing functions. Other functions that correspond to other types of processing functions can also be performed by at least one processor configured to process information 410.
[0053] With reference to Figure 4, the communication device 400 additionally includes memory configured to store information 415. In one example, the memory configured to store information 415 can include at least one non-transitory memory and associated hardware (for example, a memory controller, etc.). For example, the non-transitory memory included in the memory configured to store information 415 can correspond to RAM, flash memory, ROM, erasable programmable ROM (EPROM), EEPROM, registers, hard disk, removable disk, to a CD-ROM or any other form of storage medium known in the art. The memory configured to store information 415 may also include software that, when run, allows the associated hardware of the memory configured to store information 415 to perform its storage function (or functions). However, the memory configured to store information 415 does not correspond to isolated software, and the memory configured to store information 415 relies at least in part on the hardware.

Structural 23/67 to achieve its functionality. In addition, the memory configured to store information 415 can be implied by a different storage language, as long as the underlying function corresponds to a storage function. For example, functions such as caching, maintenance, etc., can be performed by the memory configured to store information 415 in certain contexts as being specific types of storage functions. Other functions that correspond to other types of storage functions can also be performed by the memory configured to store information 415.
[0054] With reference to Figure 4, the communication device 400 optionally also includes a set of user interface output circuits configured to present information 420. In one example, the set of user interface output circuits configured to present information 420 can include at least one output device and associated hardware. For example, the output device may include a video output device (for example, a display screen, a port that can carry video information, such as USB, HDMI, etc.), an audio output device (for example, example, speakers, a port that can carry audio information, such as a microphone connector, USB, HDMI, etc.), a vibration device and / or any other device through which the information can be formatted for broadcast or actually broadcast by a user or operator of the communication device 400. For example, if the communication device 400 matches the computer

24/67 laptop type 240 or 255 touchscreen device as shown in Figure 2A, the user interface output circuitry configured to display information 420 may include a display, such as display screen 245 or screen display touch sensitive 260. In another example, the set of user interface output circuits configured to display information 420 may be omitted for certain communications devices, such as certain UEs (for example, the wireless subscriber network module terrestrial wire 290) and / or network communications devices that do not have a local user location (for example, network switches or routers, remote servers, etc.). The user interface output circuitry configured to display information 420 may also include software that, when run, allows the associated hardware of the user interface output circuitry configured to display information 420 to perform its function (or presentation). However, the set of user interface output circuits configured to display information 420 does not correspond to isolated software, and the set of user interface output circuits configured to display information 420 relies at least in part on structural hardware to achieve its functionality. In addition, the set of user interface output circuits configured to display information 420 may be implied by a language other than presentation, provided that the underlying function corresponds to a presentation function. For example, functions like display,

25/67 issuance, request, transport, etc., can be performed by the set of user interface output circuits configured to present information 420 in certain contexts as being specific types of presentation functions. Other functions that correspond to other types of presentation functions can also be performed by the set of user interface output circuits configured to present information 420.
[0055] With reference to Figure 4, the communication device 400 still optionally includes a set of user input circuits configured to receive local user input 425. In one example, the set of user input circuits configured to receive input from Local user 425 can include at least one user input device and associated hardware. For example, the user input device may include buttons, a touchscreen display, a keyboard, a camera, an audio input device (for example, a microphone or a port that can carry audio information, such as a microphone connector, etc.) and / or any other device by which information can be received from a user or operator of the communication device 400. For example, if the communication device 400 corresponds to the laptop computer 240 or device 255 as shown in Figure 2A, the user input circuitry configured to receive local UI area 250 or 260 touchscreen display, etc. In an additional example, the user input circuitry configured to receive local user input

425 can be omitted for certain communications devices, such as certain UEs (for example, terrestrial wireless subscriber network module 290) and / or network communications devices that do not have a local user (for example, switches or routers network servers, remote servers, etc.). The user input circuit set configured to receive local user input 425 may also include software that, when run, allows the associated hardware of the user input circuit set configured to receive local user input 425 to perform its function incoming reception (or functions). However, the user input circuit set configured to receive local user input 425 does not correspond to the isolated software, and the user input circuit set configured to receive local user input 425 relies at least in part on structural hardware to achieve its functionality. In addition, the user input circuitry configured to receive local user input 425 may be implied by a language other than local receiving user input, provided that the underlying role corresponds to a receiving local user role. For example, functions such as obtaining, receiving, collecting, etc., can be performed by the set of user input circuits configured to receive local user input 425 in certain contexts as being specific types of local receiving user roles. Other functions that correspond to other types of receiving local user input functions can also be performed

27/67 by the set of user input circuits configured to receive local user input 425.
[0056] With reference to Figure 4, although the configured structural components 405 to 425 are shown as separate or distinct blocks in Figure 4 that are implicitly coupled to each other via the communication bus (not shown expressly), it will be appreciated that the hardware and / or software by which the respective structural components configured 405 to 425 realize their respective functionality can partially overlap. For example, any software used to facilitate the functionality of the structural components configured 405 to 425 can be stored in the non-transitory memory associated with the memory configured to store information 415, so that the structural components configured 405 to 425 each perform their respective. functionality (that is, in this case, software execution) based in part on the software operation stored by the memory configured to store information 415. Likewise, the hardware that is directly associated with one of the configured structural components 405 to 425 and can be borrowed or used from time to time by another component of the other configured structural components 405 to 425. For example, the at least one processor configured to process information 410 can format data in an appropriate format before being transmitted by the transceiver circuitry configured to receive and / or transmit 405 information, so that the set of transceiver circuits configured to receive and / or transmit information 405 performs its functionality (ie
Petition 870190108420, of 10/25/2019, p. 33/100
28/67 is, in this case, data transmission) based in part on the operation of structural hardware associated with at least one processor configured to process information 410.
[0057] The various modalities can be implemented in any of a variety of commercially available server devices, such as server 500 illustrated in Figure 5. In one example, server 500 can correspond to an exemplary configuration of server 170 or component network interface 300 (for example, if implemented as a core network component) as described above. In Figure 5, server 500 includes a processor 501 coupled with volatile memory 502 and a non-volatile memory with large capacity, such as a 503 disk drive. The server 500 can also include a floppy drive, a compact disk (CD) or the DVD disc drive 506 attached to processor 501. The server 500 may also include network access ports 504 attached to processor 501 to establish data connections to a network 507, such as a local area network attached to other computers, and broadcast system servers or the Internet. In the context of Figure 4, it will be appreciated that the server 500 of Figure 5 illustrates an exemplary implementation of the communication device 400, through which the set of transceiver circuits for transmitting and / or receiving information 405 corresponds to network access ports 504 used by server 500 to communicate with network 507, the at least one processor configured to process information 410 corresponds to processor 501, and the memory configuration to store information 415 corresponds to any
Petition 870190108420, of 10/25/2019, p. 34/100
29/67 combination of volatile memory 502, disk unit 503 and / or disk unit 506. The optional user interface output circuit set configured to display information 420 and the optional configured user input circuit set to receive local user input 425 are not shown explicitly in Figure 5 and may or may not be included in it. Thus, Figure 5 helps to demonstrate that the communication device 400 can be implemented as a server, in addition to a UE as in Figures 2A to 2B or as an access point as an exemplary implementation of the network component 300.
[0058] UEs, such as phones, tablet computers, desktop computers or laptop computers, are generally configured to connect to terrestrial wireless subscriber networks (e.g. 3G, 4G, 5G, etc.) with the expectation that UEs will not be airborne. For example, users are typically asked to place their respective UEs in airplane mode between takeoff and landing for commercial flights, which restricts the ability of the UEs to connect to terrestrial wireless subscriber networks.
[0059] For most manned (or piloted) aerial vehicles, altitudes and / or cruising speeds make connections to terrestrial wireless communication networks impractical. For example, the commercial aircraft can reach cruising altitudes close to 12 km at speeds of 800 to 1000 km / h. Instead of relying on wireless subscriber networks
Petition 870190108420, of 10/25/2019, p. 35/100
30/67 terrestrial to support communications to / with manned aerial vehicles, such as commercial aircraft, most countries allocate a portion of Very High Frequency (VHF) radio spectrum to define an Air Band or an aircraft band that is dedicated to radio navigation communications and / or air traffic control communications.
[0060] Regulatory agencies are increasingly authorizing the deployment of unmanned aerial vehicles (UAVs), such as commercial drones. Commercial drones are being considered to provide a variety of services, such as package delivery, search and rescue, critical infrastructure monitoring, wildlife conservation, flying cameras, surveillance and so on. Commercial drones can operate at altitudes and speeds that are best suited for connections to terrestrial wireless subscriber networks. For example, in certain environments, commercial drones can operate at cruising altitudes close to 100 m at speeds up to or near 160 km / h. However, uplink signals from commercial drones that are generally in flight create more interference for ground base stations compared to ground UEs in a non-flight state as shown in Figure 6.
[0061] With reference to Figure 6, a drone 600 is shown in a grounded position, denoted as position 1, and then in an airborne or in flight position, denoted as position 2. Three base stations (BS 1 , BS2, BS3) are depicted in Figure 6. Drone 600 is considered to include a UE that is fixed (for example, parked) to BS
Petition 870190108420, of 10/25/2019, p. 36/100
31/67
2, while UE 1 is fixed (for example, parked) to BS 1 and UE 2 is fixed (for example, parked) to BS 3. In position 1 on the ground, the uplink signals from drone 600 to BS 2 cause a first level of interference in relation to BS 1 and BS 3. In position 2 in the air, however, the uplink signals from drone 600 to BS 2 cause a second level of interference in relation to BS 1 and the BS 3 which is higher as far as the first level of interference is concerned. For example, there are fewer obstructions between drone 600 and BS 1 and BS 2 in position 2, which is one reason why interference in BS 1 and BS 3 is greater when drone 600 is in position 2.
[0062] For some drones (for example, as authorized commercial drones), the increased interference caused by drone 600 in position 2 is compensation that is considered acceptable for the purpose of providing drone 600 with connectivity during the flight. However, some drones (for example, unauthorized end-consumer devices) may not be allowed to connect to one or more terrestrial wireless subscriber networks during the flight as shown in Figure 7.
[0063] With reference to Figure 7, drone 7 00 is considered to be a commercial drone that is authorized to access a terrestrial wireless subscriber network during the flight, and is thereby fixed (for example , parked) to BS 1. In one example, drone 700 may include an integrated terrestrial wireless subscriber network module 290 to facilitate its connection to BS 1. However, drone 705 is considered to be a product of off-the-shelf consumer who is
Petition 870190108420, of 10/25/2019, p. 37/100
32/67 configured for direct line of sight (LOS) control by a respective user. However, that user modified drone 705 by attaching an UE 710. Through a wireless connection to the UE 710 on BS 1, the user of drone 705 wants to control drone 705 (for example, extending the range of drone 705, etc. .) or implement some other action (for example, taking photos or recording video using the UE 710). The wireless connection between the UE 710 and BS 1 while the UE 710 is in flight may be considered undesirable and unauthorized for certain terrestrial wireless subscriber networks, from a regulatory point of view (for example, against government regulations ) or against operator preference (for example, the operator of the terrestrial wireless subscriber network charges a premium for in-flight drone connectivity service, and the UE 710 user does not subscribe to that premium service).
[0064] Consequently, several types of disclosure refer to the management of UEs attached to the drone. As used herein, a drone-attached UE refers to any UE that is fixed, or configured to be fixed, to a drone, regardless of whether the drone-coupled UE is actually in flight. Drone-attached UEs may include authorized drone-attached UEs (for example, UEs that are authorized to be registered on a terrestrial wireless subscriber network as a drone-attached UE, for in-flight communication support, or both) and UEs unauthorized drone-coupled (e.g. UEs that are not allowed to be registered on a terrestrial wireless subscriber network with a drone-attached UE,
Petition 870190108420, of 10/25/2019, p. 38/100
33/67 for in-flight communicative support or both). In addition, as described above in relation to Figure 2B, the way in which UEs coupled to the drone are coupled to the respective drones via a physical coupling (for example, a temporary physical coupling as being taped to the drone, or a semi-permanent coupling as being integrated or embedded in a drone structure), a communicative coupling (for example, the UE coupled to the drone is communicatively linked to a controller on the drone, to allow the UE coupled to the drone to engage in the drone's flight control) or both.
[0065] Figures 8 to 9 illustrate procedures by which drone-coupled capacity information from a UE coupled to the drone (for example, the UE 200 in Figures 2A to 2B) can be transported to a network component (for example, the network component 300 of Figure 3) of a terrestrial wireless subscriber network according to the disclosure modalities. In particular, Figure 8 illustrates operation of the UE coupled to the drone, and Figure 9 illustrates operation of the network component of the terrestrial wireless subscriber network.
[0066] With reference to Figure 8, in block 800, the UE coupled to the drone transmits a message to a network component of a terrestrial wireless subscriber network that identifies capacity information coupled to the drone of the UE coupled to the drone. More specifically, the identification of the UE as having capacity information attached to the drone is configured to indicate, for the network component, that the UE coupled to the drone is capable of engaging in a flight state.
Petition 870190108420, of 10/25/2019, p. 39/100
34/67
Similarly, with reference to Figure 9, in block 900, the network component receives a message from a UE coupled to the drone that identifies capacity information coupled to the drone of the UE coupled to the drone, and in block 905, the network component determines that UE attached to the drone has the ability to engage in a flight state based on the message received.
[0067] With reference to Figures 8 to 9, in one example, message transmission in blocks 800 and 900 can be implemented during an initial coupling procedure between the UE coupled to the drone and a base station of the communication subscriber network terrestrial wireless. For example, the message from block 800 can be a UE capability signaling message (for example, new messages such as droneUE = True or droneFunctions = supported can be defined and flagged). In another example, one or more new UE categories can be defined and / or one or more defined UE categories can be reserved for UEs coupled to the drone, and the message from blocks 800 and 900 can identify the UE coupled to the drone as belonging to that reserved EU category. In another example, regulators and / or network operators of terrestrial wireless subscriber networks (for example, mobile network operators or MNOs) may assign different subscriber IDs and / or certification IDs to UEs attached to the drone that are allowed to access the network. For example, a block of subscriber IDs and / or certification IDs can be reserved for UEs attached to the drone that are authorized to access the network, so that capacity information
Petition 870190108420, of 10/25/2019, p. 40/100
35/67 attached to the drone of a UE coupled to the drone can be transported to the network component through the subscriber ID and / or certification ID assigned to the UE attached to the drone belonging to that reserved block.
[0068] With reference to Figures 8 to 9, in another example, different regulators and / or MNOs may have different criteria and / or certification procedures to authorize access to the network for UEs coupled to the drone. For example, UEs attached to the drone that are authorized to access the network can be issued with predefined keys or identification codes to be used as certificates. In one example, certificates can be encrypted. Certificates can be provided for the network component by the UE using the No Access Stratum (NAS) signaling (for example, during the initial fixing procedure, or as a subsequent dedicated RRC connection reconfiguration procedure). The network component (for example, a main network component) can perform certificate / code authentication and, if authenticated, deliver such information (for example, drone authentication success message) to the RAN by SI signaling or otherwise signaling method.
[0069] In block 910, the network component optionally implements a situation protocol coupled to the drone or a situation protocol not coupled to the drone for the UE coupled to the drone based on the determination of block 905. More specifically, it can be determined whether the service attached to the drone is generally authorized and / or whether the service attached to the drone is authorized for that UE attached to the particular drone, and the service can be
Petition 870190108420, of 10/25/2019, p. 41/100
36/67 provided (or not provided) accordingly. In one example, if the terrestrial wireless subscriber network is unable to provide drone-related service to any drone-coupled UE (for example, due to the absence of a drone-attached service authorization), a coupled status protocol service rejection drone can be implemented by default. In general, the situation protocol not attached to the drone refers to normal operation (for example, providing the same level of service to the UE coupled to the drone that is provided by the terrestrial wireless subscriber network to one or more UEs not attached to the drone), while the situation protocol attached to the drone refers to the implementation of any one of a variety of actions specifically for UEs attached to the drone that are expected to fly from time to time. These actions include, but are not limited to, any combination of the following:
• Refuse the admission of the UE attached to the drone to the terrestrial wireless subscriber network if the UE attached to the drone is not authorized for service coupled to the drone;
• Admit the drone-attached UE to the terrestrial wireless subscriber network for service only while the drone-coupled UE is not engaged in a flight state based on the drone-coupled UE that is authorized for drone-coupled service and not authorized for in-flight service;
• Admit the UE attached to the drone to the terrestrial wireless subscriber network for
Petition 870190108420, of 10/25/2019, p. 42/100
37/67 a subset of services attached to the drone while the UE attached to the drone is not engaged in a flight state, where the subset of services attached to the drone includes at least one service that is not available for UEs not attached to the drone ( that is, UEs attached to the drone are allocated for partial service even when grounded);
• Implement a power control scheme for the UE attached to the drone that is different from the power control schemes used for UEs that do not have capacity information attached to the drone; and / or • Implement a charging or charging scheme for the UE attached to the drone that is different from the charging and / or charging schemes used for UEs that do not have capacity information attached to the drone.
[0070] Figure 10A illustrates a process by which a UE coupled to the drone carries a non-flight status message according to a disclosure modality. With reference to Figure 10A, in block 1000A, the UE coupled to the drone determines whether it is currently engaged in a flight state. The determination of block 1000A can occur in a variety of ways. For example, the UE coupled to the drone can be communicatively coupled to a drone, which notifies the UE coupled to the drone if the drone is currently engaged in flight status (or flight mode), for example, based on the situation of one or more of its mechanical or electrical components. On a
Petition 870190108420, of 10/25/2019, p. 43/100
38/67 another example, several measurements (for example, speed, altitude, etc.) made independently by the UE coupled to the drone may be sufficient for the UE coupled to the drone to determine and / or differentiate between its situation in flight or on land. In one example, such determination may be based on a reference altitude / weight limit, that is, the current altitude / weight of the UE attached to the drone meets the borderline requirement, so the UE is considered to be in a state of flight. In one example, the determination can be based on the speed of the UE coupled to the drone. In another example, the determination may be based on direction beyond speed (that is, acceleration). In another example, the determination may be based on the combination of the above. In one example, such a limit (or limits) (for example, reference weight, border weight, speed, acceleration, etc.) can be provided by the network to the UE.
[0071] With reference to Figure 10A, in block 1005 A, the UE coupled to the drone transmits a message to a network component of a terrestrial wireless subscriber network that indicates a result of the determination of block 1000A. In one example, the message from block 1005 A can expressly indicate whether the UE coupled to the drone is currently engaged in the flight state (for example, through dedicated RRC signaling). For example, the message from block 1005 A can be a measurement report message configured with a new parameter, such as nowFlying = True or nowFlying = False. In another example, the UE attached to the drone may have different identifiers for use during land mode and flight mode (for example, Mobile Subscriber Identities
Petition 870190108420, of 10/25/2019, p. 44/100
39/67
International (IMSIs), new Globally Unique Temporary Identifier (GUTI) when the UE attached to the drone is in flight status, different code / certificate ID, etc.). The drone-coupled UE can use these different IDs to communicate whether the drone-coupled UE is operating in the flight state or in a non-flight state.
[0072] With reference to Figure 10A, in another example, the message from block 1005 A may facilitate some action to be taken and / or request that some action be taken based on the determination of block 1000 A without necessarily providing an express indication for the network component if the UE attached to the drone is currently engaged in the flight state. For example, as described below in relation to Figure 12A, the UE coupled to the drone may request a transfer protocol transition in response to a detected transition from the UE coupled to the drone between the flight state and the non-flight state. In another example, as described below in Figure 12A, the UE coupled to the drone can request a power control protocol transition in response to a detected transition from the UE coupled to the drone between the flight state and the non-flight state. Such requests may qualify as direct indications to the network component regarding the flight situation of the UE attached to the drone (for example, a request to transition from the UE attached to the drone to a flight status transfer protocol may imply in a transition from the drone-coupled UE to the flight state, while a request to transition from the drone-coupled UE to a non-flight state transfer protocol can
Petition 870190108420, of 10/25/2019, p. 45/100
40/67 imply a transition from the drone-coupled UE to the non-flight state, and a request to transition from the drone-coupled UE to a flight-state power control protocol may imply a transition from the coupled UE to the drone to the flight state, while a request to transition the drone-coupled UE to a non-flight state power control protocol may imply a transition from the drone-coupled UE to the non-flight state). In another example, the message from block 1005 A can make it easier for the network component to take action (or actions) to be taken without explicitly requesting that the action (or actions) be taken.
[0073] With reference to Figure 10A, in another example, the message from block 1005 A can be transmitted to the network component in an event-driven manner each time a flight situation of the UE coupled to the drone changes (for example example, each time the EU transitions coupled to the drone between the flight state and the non-flight state). For example, the UE coupled to the drone can continuously monitor various parameters (for example, altitude / weight, speed, direction of movement, etc.) and can transmit the message from block 1005 A since one or more of the parameters crosses the respective limit (or respective limits) (for example, which can be provided to the UE attached to the drone over the network). In another example, the message from block 1005 A can be transmitted to the network component in each case of a periodic message (for example, the measurement report message noted above) regardless of the possibility of the flight situation of the coupled UE the drone has changed.

In addition, the process of Figure 10A can perform the process of Figure 8 in at least one example.
[0074] Figure 10B illustrates a process by which a network component receives a non-flight status message to a UE coupled to the drone according to a disclosure modality. The process of Figure 10B is implemented in a network component (for example, the network component 300 of Figure 3) of a terrestrial wireless subscriber network, such as a RAN component or major network component.
[0075] With reference to Figure 10B, in block 1000B, the network component receives a message from a UE coupled to the drone that indicates whether the UE coupled to the drone is engaged in a flight state. For example, the message received in block 1000B may correspond to the message transmitted by the UE coupled to the drone in block 1005 A of Figure 10A.
[0076] In block 1005B, the network component optionally implements a flight status protocol or a non-flight status protocol for the UE coupled to the drone based on the message received in block 1000B. In general, the non-flight status protocol refers to normal operation (for example, providing the same level of service for the drone-attached UE as provided by the terrestrial wireless subscriber network for one or more unbound UEs to the drone), while the flight status protocol refers to the implementation of any of a variety of actions specifically for UEs in flight. These actions include, but are not limited to, any of the actions described below in relation to 1105 A in Figure 11A.
Petition 870190108420, of 10/25/2019, p. 47/100
42/67
[0077] Figure 11A illustrates a process for implementing a flight status protocol or non-flight status protocol for a UE coupled to the drone according to a disclosure modality. The process of Figure 11A is implemented in a network component (for example, network component 300 of Figure 3) of a terrestrial wireless subscriber network, such as an RAN component or major network component.
[0078] With reference to Figure 11 A, in block 1100 A, the network component determines whether a UE coupled to the drone is engaged in a flight state based on one or more wireless signals transmitted by the UE coupled to the drone. Block 1100A determination can occur in a variety of ways. In a first example, the determination of block 1100A can be based on a message from the UE coupled to the drone (for example, the message can correspond to one or more wireless signals if the network component is an access network component, or alternatively, to the message loaded on one or more wireless signals and then carried to the network component via a return if the network component is a main network component), such as an express flight status notification message received UE attached to the drone (for example, through dedicated RRC signaling), a request to perform an action (or actions) that indirectly indicate the flight status or non-flight status, inclusion of an identifier that is specific for the flight state or for the non-flight state and so on, as described in relation to block 1005 A of Figure 10A or block 1000B of Figure 10B.
Petition 870190108420, of 10/25/2019, p. 48/100
43/67
[0079] In a second example, the determination of block 1100A can have as other types of messages from the UE coupled to the drone, such as report of measurement of current position data of the UE coupled to the drone including elevation / altitude. For example, the network component can compare a current height of the drone-coupled UE with a height limit to determine whether the drone-coupled UE is engaged in the flight status or not (for example if the current height of the drone-coupled UE) is above the height limit, then the flight status is determined for the UE attached to the drone). A speed of the UE coupled to the drone can also be taken into account in the determination. For example, the network component can compare a current velocity of the UE coupled to the drone with a speed limit to determine whether the UE coupled to the drone is engaged in the flight state or not (for example, if the current velocity of the UE coupled to the drone). drone is above the boundary speed, so the flight status is determined for the UE coupled to the drone). In another example, the determination may be based on the direction of movement of the UE coupled to the drone in addition to the speed (that is, acceleration). In yet another example, the determination may be based on the combination of the above.
[0080] With reference to block 1100A of Figure 11A, in a third example, the determination of block 1100A can be based on the internal coordination of different cells (or base stations) of the terrestrial wireless subscriber network. For example, the network component can compare power received from one or more uplink signals from the UE coupled to the drone when measured
Petition 870190108420, of 10/25/2019, p. 49/100
44/67 at different base stations (for example, both close to the UE coupled to the drone and far from the UE coupled to the drone). Due to the increased spread of free space for UEs coupled to the drone in flight status, base stations furthest from the UE coupled to the drone (for example, in addition to a distance limit) that measure the uplink signals of UE coupled to the drone drones as intense (for example, above an uplink signal strength limit) can be an indicator that the UE coupled to the drone is engaged in the flight state.
[0081] In another example, a UE mobility pattern coupled to the drone can be assessed. UEs attached to the drone engaged in flight status are expected to have less frequent transfers (for example, due to environmental changes and loss of propagation over time being more predictable), so that direct neighbor cells can be skipped during automation, which is not normally the case for UEs that are not in flight. This scenario is shown in Figure 11B, through which an UE coupled to drone 1100B automates directly from BS A to BS C (jumping or bypassing intermediate BS B), while UE 1105B (which is not in flight) automates from BS A to BS B, and then later from BS B to BS C. It will be appreciated that UE automations are determined in part based on the wireless signal (or signals) from the UE, so this example from block 1100A it is also based in part on the wireless signal (or signals) of the UE coupled to the drone.
[0082] With reference to block 1100A of Figure 11 A, in a fourth example, the determination of block 1100A
Petition 870190108420, of 10/25/2019, p. 50/100
45/67 can be based on an estimated angle of arrival of an uplink signal from the UE coupled to the drone. For example, with multiple antenna technologies, a base station can estimate the arrival angle of the uplink signal received from the UE coupled to the drone (for example, based on one or more arrival angle measurements). Then, the base station (or another network component for which the base station reports the arrival angle) can estimate whether a transmitter in the UE coupled to the drone is on the ground or above ground (that is, in a state flight) by comparing the angle of arrival to a borderline angle.
[0083] In block 1105 A, the network component optionally implements a flight status protocol or a non-flight status protocol for the UE coupled to the drone based on the determination of block 1100A. In general, the non-flight status protocol refers to normal operation (for example, providing the same level of service for the drone-attached UE as provided by the terrestrial wireless subscriber network for one or more unbound UEs to the drone), while the flight status protocol refers to the implementation of any of a variety of actions specifically for UEs in flight. These actions include, but are not limited to, any combination of the following:
• Refuse admission of the drone coupled UE to the terrestrial wireless subscriber network if the drone coupled UE is unauthorized for drone coupled service and / or flight status service, and / or if the subscriber network of terrestrial wireless communication is unable to provide service coupled to the
Petition 870190108420, of 10/25/2019, p. 51/100
46/67 drone and / or flight status service. In one example, whether the UE attached to the drone is authorized or not authorized for service attached to the drone and / or for flight status service can be determined by consulting a Domestic Subscriber Server (HSS) on the main network of the subscriber network of terrestrial wireless communication. For example, subscriber information for the UE attached to the drone can be stored as part of the Universal Integrated Circuit Card (UICC) or UE configuration. In an additional example, new cause values for connection rejection can be established to notify an UE attached to the unauthorized drone regarding refusal of admission (eg, non-A-Drone, droneServiceUnavailable, etc.). Alternatively or additionally, in another example, new messages can be defined to signal whether UEs attached to the particular drone are authorized for service. Therefore, the absence of such a message may indicate that the private service is not authorized for that UE coupled to the private drone. Such signaling can be based on the dedicated RRC signaling, as discussed below in relation to Figure 13: • Authorizing restricted or limited service (for example, lower transmission power, lower bandwidth or QoS, etc.) for the UE attached to the drone to the terrestrial wireless subscriber network if the UE attached to the drone is not
Petition 870190108420, of 10/25/2019, p. 52/100
47/67 authorized for service attached to the drone and / or flight status service, but it is in a flight state. Once it is determined that the UE coupled to the drone is no longer engaged in the flight state, then the UE coupled to the unauthorized drone can be disconnected from the terrestrial wireless subscriber network. In addition, the UE coupled to the unauthorized drone can subsequently be optionally blacklisted from the terrestrial wireless subscriber network for violating the terms of use for the UE coupled to the unauthorized drone;
• Authorize the service for the UE coupled to the drone while evaluating a sub-fee for a UE account coupled to the drone if it is not signed for the service coupled to the drone and / or flight status service;
• Implement a power control scheme for the UE coupled to the drone in the flight state that is different from the power control schemes used for UEs coupled to the drone that are not in the flight state;
• Implement a different charging and charging scheme for the UE coupled to the drone in the flight state which is different from the charging and charging schemes used for UEs coupled to the drone that are not in the flight state; and / or • Implement a different transfer scheme for the UE coupled to the drone in the flight status that is different from a
Petition 870190108420, of 10/25/2019, p. 53/100
48/67 transfer used for UEs coupled to the drone in a non-flight state (for example, discussed in more detail in relation to Figures 12A to 12B). [0084] As discussed above in relation to Figures 11A to 11B, the transfer characteristics associated with a UE coupled to the drone in flight may be different from a grounded or ground UE. For example, the rate at which a UE coupled to the drone in flight automates between base stations may, in general, be less than a typical grounded or ground UE, and UEs coupled to the drone in flight may be more likely to jump or circumvent intermediate base stations, as shown in Figure 11B. In addition, a radio link failure rate (RLE) may be lower for UEs coupled to the drone in flight compared to grounded or ground UEs due to the UEs coupled to the drone in flight are more likely to have a direct LOS for their stations- service base and / or more loss of deterministic trajectory. In other words, there are few obstructions at higher altitudes, so a sudden RLE is less likely for UEs attached to the in-flight drone.
[0085] Figure 12A illustrates an exemplary implementation of the process in Figure 11A according to a disclosure modality. With reference to Figure 12A, in block 1200 A, the network component determines whether a UE coupled to the drone is engaged in a flight state. Block 1200A can be implemented using any of the methodologies described in relation to block 1100A of Figure 11A. In block 1205 A, the network component optionally implements a data transfer protocol
Petition 870190108420, of 10/25/2019, p. 54/100 flight status or a non-flight status transfer protocol to the UE coupled to the drone based on the determination of the 1200A block. As will be appreciated, block 1205A represents an example of block 1100A of Figure 11 A specific for transfer.
[0086] With reference to Figure 12A, in one example, the flight status transfer protocol can be configured with new hysteresis parameters and transfer limits that are customized (or optimized) for conditions associated with expected UEs coupled to the drone. In addition, the process of Figure 12A can be repeated each time the network component makes a new determination whether the UE coupled to the drone is engaged in the flight state or in the non-flight state.
[0087] In one example, to avoid a ping-pong effect while the UE attached to the drone is actively connected to the terrestrial wireless subscriber network (for example, RRC Connected mode), a different set of limits to characterize a UE coupled to the drone as being in flight or non-flight status can be used for the purpose of making a transfer protocol switching decision as for other flight / non-flight status determinations. In other words, the determination of block 1200A can be configured to provide a high degree of confidence that the UE coupled to the drone has actually been switched between flight status and non-flight status before the transfer protocol is authorized to be switched. For example, a standard minimum weight limit to qualify for flight status is normally considered to be 30 m. Now, it is considered
Petition 870190108420, of 10/25/2019, p. 55/100
50/67 additionally that a UE coupled to the drone is determined to be in a non-flight state, so that the network component is implementing a non-flight state transfer protocol to UE coupled to the drone. In this case, the minimum weight limit for implementing a transfer protocol transition can be increased (for example, 40 m, 50 m, etc.) to avoid the ping-pong effect. Thus, different limits and / or parameters can be used to assess the ground or flight situation of a UE coupled to the drone in certain circumstances. Thus, a brief fall (or drop in altitude) of the UE attached to the drone during the flight will not trigger a change in transfer protocol, and similarly, a false start (or rapid increase in altitude followed by a return to the ground) ) will not trigger a transfer protocol change. In an additional example, the various limits and / or parameters used to assess the ground or in-flight situation of a UE coupled to the drone can be configurable (for example, with the use of dedicated RRC signaling or a broadcast SIB), for all UEs attached to the drone or for particular groups or classes of UEs attached to the drone.
[0088] In an additional example, although the UE attached to the drone is actively connected to the terrestrial wireless subscriber network (for example, RRC Connected mode), a UE attached to the drone can provide assistance information for the component of network that is configured to request implicitly or expressly for a transfer protocol transition (for example, described above in relation to block 1005 A of Figure 10A or block 1000B of Figure
Petition 870190108420, of 10/25/2019, p. 56/100
51/67
10B). In one example, assistance information may be based on a current channel and / or interference environment from the UE coupled to the drone as detected through its own measurements. For example, the drone-coupled UE can transmit assistance information to request a transfer protocol transition in response to a determination that the drone-coupled UE has transitioned between flight status and non-flight status (e.g., the drone-coupled UE can begin to see many more neighboring base stations and determine that the drone-coupled UE is more likely to be in flight, so that the flight status transfer protocol is now preferred, which triggers the request to be sent). Consequently, the situation of the UE coupled to the drone as being in flight or landed on block 1200A can be inferred from a message from the UE coupled to the drone requesting a particular transfer protocol, which can occur as described above in relation to the block 1005 A of Figure 10A or block 1000B of Figure 10B in an example.
[0089] With reference to Figure 12A, it is possible that a UE coupled to the drone can be engaged in the flight state while it is still in an idle mode (for example, RRC Idle) in relation to the terrestrial wireless subscriber network. For example, the UE coupled to the drone can be controlled via a completely different type of network (e.g., a satellite network, a direct LOS control system, a different terrestrial wireless subscriber network, etc.). In such cases, the network component will consider that the UE coupled to the drone is inactive even while the UE coupled to the drone
Petition 870190108420, of 10/25/2019, p. 57/100
52/67 drone is engaged in flight status. These inactive and in-flight drone UEs can be controlled by some mechanisms other than the terrestrial wireless subscriber network, but you may still want to connect to the terrestrial wireless subscriber network from time to time (for example, to start transmitting audio and / or video data).
[0090] For these reasons, in at least one mode, different flight status transfer protocols can be established based on the possibility that a UE coupled to the drone in flight is in Connected or Idle mode in relation to the subscriber network of terrestrial wireless communication.
[0091] In Idle mode, a Tracking Area Identifier (TAI) list can be used to determine a general area where the UE attached to the Idle drone is located. The size of the TAI list determines the size of a paging radius for the UE coupled to the Inactive drone in the event that the UE coupled to the Inactive drone needs to be paged over the terrestrial wireless subscriber network. As noted above, unlike terrestrial UEs, UEs coupled to the drone in flight may be more likely to reselect cells from different IAT lists due to the different mobility patterns of the UEs coupled to the drone in flight. In other words, more neighboring cells will, in general, be in the service range of UEs coupled to the in-flight drone, so that UEs coupled to the in-flight drone have more options in terms of reselling neighbor cells. Consequently, the flight status transfer protocol may include a
Petition 870190108420, of 10/25/2019, p. 58/100
53/67 larger paging radius and / or a reselection list that encompasses cells in a larger area in relation to the non-flight state transfer protocol.
[0092] For example, a list of TAI 1 (or TAI1) contains cells {1, 2, 3, 4}, while a list of TAI 2 (or TAI2) contains cells {5, 6, 7 , 8}. A terrestrial Inactive UE or grounded UE can perform a Tracking Area Update (TAU) only when the Inactive UE goes from cell 4 to 5, for example, while a UE coupled to the drone in Inactive flight when parked in cell 2 can also see cell 6 or 7 as the appropriate cell. This can trigger more frequent TAUs for the UE coupled to the drone in the Inactive flight if only TAI1 or TAI2 is allocated to the UE coupled to the drone in the Inactive flight. On the other hand, if the network component (for example, an MME) allocates TAI1 + TAI2 (the joint set of the two, for example, which is {1, 2, 3, 4, 5, 6, 7, 8} in the example above) as a TAI for the UE coupled to the Inactive flight drone, the reporting frequency (e.g. TAUs) can be reduced from the UE coupled to the Inactive flight drone. Consequently, the flight status transfer protocol can include one or more different location reporting parameters (for example, reduced location reporting) while in Idle mode compared to the non-flight status transfer protocol.
[0093] In a specific example of LT, an eNB may need to report whether the UE attached to the Idle drone is in the air (or engaged in flight status, ie in flight) to the MME on a periodic basis so that the MME can update
Petition 870190108420, of 10/25/2019, p. 59/100
54/67 the corresponding TAI list for the UE coupled to the Inactive drone. In one example, eNB can report measurement information in relation to the UE coupled to the Inactive drone to the MME (for example, current height / altitude), or alternatively, it can expressly indicate to the MME whether the UE coupled to the Inactive drone is engaged in flight or non-flight status. In an example where eNB reports the height of the UE coupled to the Inactive drone to the MME, the MME can determine whether the UE coupled to the Inactive drone is flying or not by comparing a reported height of the UE coupled to the Inactive drone to a boundary height. In an additional example, one or more new boundary parameters can be introduced for inactive mode reselection for UEs coupled to the in-flight drone. For example, a different value for SintraSearchP can be implemented for UEs coupled to the in-flight drone as part of the flight status transfer protocol compared to UEs that are not in flight. Although this particular example is specific to LTE, it will be appreciated that other modalities can be targeted for any wireless communications scheme (eg NR 5G, etc.).
[0094] Figure 12B illustrates a more detailed implementation of the process in Figure 12A according to a disclosure modality. Referring to Figure 12B, in block 1200B, a network component of a terrestrial wireless subscriber network determines a UE coupled to the drone to be engaged in a flight state. In block 1205B, the network component determines whether the UE attached to the drone is in an Idle mode or a Connected mode in relation to the wireless subscriber network
Petition 870190108420, of 10/25/2019, p. 60/100
55/67 terrestrial. If the network component determines that the UE attached to the drone is in an Idle mode in relation to the terrestrial wireless subscriber network in block 1205B, the network component implements an Inactive flight state transfer protocol for the attached UE to the drone on block 1210B. Otherwise, if the network component determines that the UE coupled to the drone is in a Connected mode in relation to the terrestrial wireless subscriber network in block 1205B, the network component implements a Connected flight state transfer protocol to the UE coupled to the drone in block 1215B.
[0095] With reference to Figure 12B, in block 1220B, the network component determines whether any situation has occurred that is sufficient to trigger a transfer protocol transition to the UE coupled to the drone. Examples of situation changes that are sufficient to trigger a transfer protocol transition to the drone-coupled UE may include a transition from the drone-coupled UE from Connected to Idle mode (or vice versa) or from flight status to the non-flight status. Although not shown expressly in Figure 12B, if the network component determines that no situation change has occurred that is sufficient to trigger a transfer protocol transition to the UE coupled to the drone in block 1220B, the network component keeps the UE attached to the drone in your current transfer protocol. If the network component determines that the UE attached to the drone has transitioned between Connected and Idle mode while it is still engaged in the flight state on block 1220B, the process returns to block 1205B and a
Petition 870190108420, of 10/25/2019, p. 61/100
56/67 different flight status transfer protocol is implemented for the UE coupled to the drone. If the network component determines that the UE coupled to the drone has transitioned to the non-flight state in block 1220B, the network component switches the UE coupled to the drone to the non-flight state transfer protocol at 1225B. The process then returns to block 1200B, where the network component monitors the UE coupled to the drone to determine whether the UE coupled to the drone re-engages the flight state.
[0096] Figure 13 illustrates a process by which a network component (for example, a RAN component or main network component) of a terrestrial wireless subscriber network transports a support situation available for the service related to drone according to a development mode. In block 1300, the network component configures a message indicating a degree to which the terrestrial wireless subscriber network supports the service for one or more UEs coupled to the drone. In block 1305, the network component transmits the configured message.
[0097] With reference to Figure 13, the message configured in block 1300 and transmitted in block 1305 can be a dedicated message (for example, single broadcast) that is intended for a particular target UE or a broadcast message that is intended more generally UEs that are served by the terrestrial wireless subscriber network.
[0098] With reference to Figure 13, in an example where the message transmitted in block 1305 is a
Petition 870190108420, of 10/25/2019, p. 62/100
57/67 dedicated message (or single broadcast), the message in block 1305 can be deployed through dedicated Radio Resource Control (RRC) signaling using a new Information Element (IE) and / or a new existing field (or fields) in IE (or lEs):
RRCConnectionSetupComplete-vXXYY-IEs :: = SEQUENCE {uav-Services-rXX ENUMERATED {supported} OPTIONAL, nonCriticalExtension SEQUENCE {} OPTIONAL}
[0099] With reference to Figure 13, in an example in which the message transmitted in block 1305 is a broadcast message, the message in block 1305 can be broadcast through a System Information Block (SIB) message. In a further example, the support of UEs coupled to certain types of UAVs may be restricted / allowed by reusing an Access Class Bus (ACB) method in which information about allowed / barred access classes is disseminated through a SIB. In an additional example, certain terrestrial wireless subscriber networks may support service for UEs coupled to the drone while other terrestrial wireless subscriber networks do not. In that case, the message in block 1305 can simply indicate whether the UEs coupled to the drone are supported or not, for example, as a flag]. In one example, some UEs coupled to the drone may still access terrestrial wireless subscriber networks on barred terrestrial wireless subscriber networks, but only with the use of normal procedures that do not involve their situations coupled to the drone (for example, example, provided that
Petition 870190108420, of 10/25/2019, p. 63/100
58/67
UEs attached to the drone are positioned in terrestrial mode, or grounded, and do not actually engage in the flight state).
[0100] However, the service bus coupled to the drone could also be announced more. For example, ACB may depend on the type of traffic or drone classes. For example, a UE coupled to the drone that uses the terrestrial wireless subscriber network for continuous video transmission may be barred, but a UE coupled to the drone that uses the terrestrial wireless subscriber network for telemetry may not be barred. Alternatively or additionally, a UE coupled to the drone may belong to different drone classes depending on the services it needs, among which some services can be barred while others are not barred. In such a case, the UE attached to the drone may wish to initiate limited service drone operation. As examples, the bus criteria can be like:
• Bar all UEs attached to the drone, • Bar all UEs coupled to the drone that are engaged in the flight state, or • Bar all UEs attached to the drone that are engaged in the flight state while capturing videos that do not refer to a public service function.
[0101] Figure 14 illustrates a process by which a UE coupled to the drone determines whether to request the service (and / or how many services to request) from a terrestrial wireless subscriber network according to a disclosure modality. In block 1400, the UE is coupled
Petition 870190108420, of 10/25/2019, p. 64/100
59/67 the drone receives a message indicating a degree to which a terrestrial wireless subscriber network supports service to one or more UEs coupled to the drone. For example, the message received in block 1400 may correspond to the message transmitted in block 1305 of Figure 13 (for example, through a single broadcast protocol, such as dedicated RRC signaling, or a broadcast protocol, such as a flag in a SIB or ACB via a SIB). In block 1405, the UE coupled to the drone selectively requests service from the terrestrial wireless subscriber network based in part on the received message. In particular, in block 1405, the UE attached to the drone can compare the degree to which the terrestrial wireless subscriber network supports service (for example, to the UE coupled to the drone specifically or to a class of UE coupled to the drone to the which UE attached to the drone belongs) to its own service requirement to determine how many (if any) service to request from the terrestrial wireless subscriber network.
[0102] Figure 15 illustrates an exemplary implementation of the process in Figure 14 according to a disclosure modality. In particular, Figure 15 illustrates a specific example of broadcasting the drone service availability message described above in Figure 14, although it is appreciated that other modalities can be targeted for dedicated (or single broadcast) implementations of the service availability message. drone.
[0103] With reference to Figure 15, it is considered that a UE coupled to the drone is connected to a network of
Petition 870190108420, of 10/25/2019, p. 65/100
60/67 terrestrial wireless subscriber in a non-flight state (for example, terrestrial mode) and wants to initiate the flight mode that requires in-flight drone service from the terrestrial wireless subscriber network. In block 1500 (for example, as in 1400 in Figure 14), the UE coupled to the drone acquires and decodes a SIB corresponding to the access control to the drone. In block 1505, the UE coupled to the drone determines whether the SIB indicates whether the UE coupled to the drone is barred from in-flight drone service from the terrestrial wireless subscriber network. If so, in block 1510, the UE attached to the drone does not initiate flight mode and, instead, remains in ground mode. However, if the UE attached to the drone determines that the SIB indicates that the UE attached to the drone is not barred from in-flight drone service from the terrestrial wireless subscriber network in block 1505, then the UE attached to the drone initiates the transition to flight mode on block 1515.
[0104] Figure 16 illustrates an exemplary implementation of the process in Figure 14 according to another embodiment of the disclosure. Figure 16 is similar to Figure 15, but Figure 16 refers to an implementation that involves more advertised bus rules for drone-related services.
[0105] With reference to Figure 16, it is considered that a UE coupled to the drone is connected to a terrestrial wireless subscriber network in a non-flight state (for example, terrestrial mode) and wishes to start the flight mode with the use of one or more private in-flight drone services over the terrestrial wireless subscriber network. In block 1600 (for example, as in 1400 from
Petition 870190108420, of 10/25/2019, p. 66/100
61/67
Figure 14), the UE coupled to the drone acquires and decodes a SIB corresponding to the access control to the drone. In block 1605, the drone-attached UE determines whether the SIB indicates whether the drone-attached UE is barred from each of the one or more in-flight drone services of the terrestrial wireless subscriber network that are desired by the UE coupled to the drone. If so, in block 1610, the UE coupled to the drone does not initiate flight mode and, instead, remains in terrestrial mode. However, if the UE coupled to the drone determines that the SIB indicates that the UE coupled to the drone is not barred from each of the one or more in-flight drone services of the terrestrial wireless subscriber network that are desired by the UE coupled to the drone. drone in block 1605, then the UE coupled to the drone determines whether the SIB indicates that the UE coupled to the drone is barred from any one or more in-flight drone services of the terrestrial wireless subscriber network that are desired by the UE coupled to the drone in block 1615.
[0106] With reference to Figure 16, if the UE attached to the drone determines that each of the one or more of its desired in-flight drone services is available in block 1615, then the full service flight mode is initiated in block 1620 Alternatively, if the UE attached to the drone determines that less than all of the services of its in-flight drone services are available in block 1615, then the limited service flight mode is initiated in block 1625 with the use of service (s ) in-flight drone available.
[0107] As will be appreciated from an analysis of Figures 15 to 16, the UE coupled to the drone can
Petition 870190108420, of 10/25/2019, p. 67/100
62/67 initiate a transition from the drone-coupled UE in a flight state if the indicated degree to which the terrestrial wireless subscriber supports the service for drone-coupled UEs is above a threshold, and the drone-coupled UE can delay the initiation of the transition of the UE coupled to the drone in the flight state if the indicated degree to which the terrestrial wireless subscriber supports the service for UEs coupled to the drone is not above the limit.
[0108] In relation to Figures 13 to 16, a modality is directed to a method of operating a network component of a terrestrial wireless subscriber network, which comprises configuring a message indicating a degree at which the subscriber of terrestrial wireless communication supports the service to one or more UEs coupled to the drone, and transmit the configured message. In one example, the transmission transmits the configured message as a dedicated message that is intended for a single UE coupled to the drone. In an additional example, the dedicated message is implemented through dedicated RRC signaling using at least one IE. In a further example, the transmission transmits the configured message as a broadcast message (for example, through a SIB and / or through an ACB protocol) that is intended for multiple UEs. In an additional example, the indicated degree to which the terrestrial wireless subscriber supports the service for the one or more UEs coupled to the drone is one among all the UEs coupled to the drone, the bus of all UEs coupled to the engaged drone in a flight state and / or bus of all UEs coupled
