[0001] [0001] Obtaining the location of a mobile device that is accessing a wireless network can be useful for many applications including, for example, emergency calls, personal navigation, asset tracking, location of a friend or family member, etc. In Fifth Generation (5G) networks, a 5G control plan localization solution currently being developed by the Third Generation Society Project (3 GPP) is expected to support localization for different Radio Access Technologies (RATs) (for example, Long Term Evolution (LTE), New Radio (NR), WiFi etc.) and allow user equipment (EU) to change RAT before or during a location session. However, this can result in a location server not knowing the current RAT in service for a UE and / or a change in RAT in service by a UE while obtaining location measurements or a location estimate. These events are fully supported by current control plan location solutions for wireless networks. Enabling location support on a 5G network for a UE with an unknown RAT in service and / or where a UE changes RAT during positioning execution, can thus be an advantage. SUMMARY

In addition, multiple occurrences of an element can be indicated by following a first number for the element with a letter or a hyphen and a second number. For example, multiple occurrences of an element 110 can be indicated as 110-1, 110-2, 110-3 etc. or as l110a, 110b, 110c etc. When referring to such an element using only the first number, any occurrence of the element must be understood (for example, element 110 in the previous example would refer to elements 110-1, 110-2 and 110-3 or elements 110a, 110b and 1100). DETAILED DESCRIPTION
[0032] [0032] Obtaining the location of a mobile device that is accessing a wireless network can be useful for many applications including, for example, emergency calls, personal navigation, asset tracking, location of a friend or family member etc. On 5G networks, it will be possible for a UE to move between different types of access through handover, cell change or RAT change while still accessing the same Mobility and In-Service Access (AMF) Function on a 5G Core Network (5GCN). The types of access currently defined by 3GPP for a 5GCN comprise new Radio (NR) supported by NR NodeBs, also referred to as gNBs, LTE or developed LTE (eLTE) supported by next generation developed NodeBs (ng-eNBs) and WiFiG (also referred to as Wi-Fi) supported by untrusted or trusted wireless Local Area Networks (WLANs). But in the future there may be other types of access (for example, Bluetootho). The ability to preserve the same AMF In Service can enable a 5G control plan location solution to support location for different RATs (for example, LTE, NR, WiFi) and can allow a UE to change RAT during a session. location. However, this may also mean that a location server in a 5GCN (for example, a Location Management Function (LMF)) may not know the RAT in current service for a UE and / or that a UE may change RAT in service during a positioning procedure. None of these events can be fully supported by the control plan location solution defined in Technical Specification 3GPP (TS) 23.271 for long term Evolution (LTE) access by a UE and, instead, a location server (for example, a Mobile Location Center in enhanced service (E-SMLC)) may need to restart a location session or leave it. Enabling full location support on a 5GCN for a UE with an unknown RAT in service and / or where a UE changes RAT during a location session could thus be an advantage.
[0033] [0033] The modalities described in the present invention provide common (or generic) positioning procedures for 5G that support multiple RATs. For example, an improved cell ID (ECID) procedure based on a generic network could be supported by the NR A Positioning Protocol (NRPPa), defined in 3GPP TS 38.455, which is (or can be) applicable to NR access on a qNB in service, LTE access in a ng-eNB in service and WiFi access in a WLAN in trusted or unreliable service. Similarly, a Difference of
[0034] [0034] As used in the present invention, the term "unknown", in the context of a UE having an "unknown" RAT in service, an "unknown" RAT in service for a location server or a similar description, means that a server The location code has no information identifying which RAT (for example, from a plurality of RATSs that can potentially function as the RAT in service for the UE) is the current RAT in service for a UE. A person of ordinary skill in the art will recognize that such scenarios can occur in a variety of circumstances.
[0035] [0035] In current positioning protocols such as the LTE Positioning Protocol (LPP) defined in 3GPP TS 36.355, the LPP Extensions protocol (LPPe) defined by the Open mobile Alliance (OMA) and the LPP protocol
[0036] [0036] According to modalities, these problems can be overcome using generic position methods that allow positioning a target UE that is served by any one (or more) of a number of different RATs and that allow measurements by a UE of nodes of access belonging to different RATs and / or measurements of a UE by access nodes for different RATs. With a generic position method, a common set of procedures, messages and parameters can be defined that are applicable to a number of different RATs and that support different variants of a common generic position method for different RATs. In addition to enabling location support for multiple RATs, such generic position methods can reduce implementation by reusing the same set of procedures, messages and parameters for multiple RATs. Some specific examples of this are described below.
[0037] [0037] Although the transmission of a Positioning Reference Signal (PRS) to support the location of mobile devices is described in the present invention, the transmission of other types of signal such as a Cell Specific Reference Signal (CRS) or Tracking reference (TRS) can be used for some wireless technologies (for example, such as 5G NR). Consequently, the methods exemplified in the present invention to support location measurements for PRS transmission can also be applicable to the transmission of other signals used for positioning such as a CRS or TRS.
[0038] [0038] Figure 1 shows a diagram of a communication system 100, according to a modality. Communication system 100 can be configured to determine the location of a UE 105 by using access nodes 110, 114, 116 and / or a location server (LMF 120) to implement one or more positioning methods. Here, the communication system 100 comprises a UE 105, and components of a 5G network comprising a Next Generation Radio Access Network (RAN) (NG) (NG-RAN) 135 and a 5G core Network (5GCN) 140. One 5G network can also be referred to as an NR network; NG-RAN 135 can be referred to as a 5G RAN or as an NR RAN; and 5GCN 140 can be referred to as a NG Core network. The standardization of an NG-RAN and 5GCN is continuous in 3GPP. As a result, NG-RAN 135 and 5GCN 140 can conform to current or future standards for 5G support from 3GPP. The communication system 100 can additionally use information from space vehicles (SVs) 190 to a Global Navigation Satellite System (GNSS) such as GPS, GLONASS, Galileo or Beidou or some other local or regional Satellite Positioning System (SPS ) such as IRNSS, European Geostationary Navigation Coverage Service (EGNOS) or Remote Area Augmentation System (WAAS). Additional components of the communication system 100 are described below. Communication system 100 may include additional or alternative components.
[0039] [0039] It should be noted that figure 1 provides only a generalized illustration of various components, all or any of which can be used as appropriate, and each of which can be duplicated or omitted as needed. Specifically, although only one UE 105 is illustrated, it will be understood that many UEs (for example, hundreds, thousands, millions, etc.) can use communication system 100. Similarly, communication system 100 may include a greater (or lesser) number ) of SvVs 190, gNBs 110, ng-eNBs 114, WLANS 116, AMFs 115, eternal customers 130 and / or other components. The illustrated connections that connect the various components in the communication system 100 include data and signaling connections that may include additional components (intermediaries), direct or indirect physical and / or wireless connections and / or additional networks. In addition, components can be rearranged, combined, separated, replaced, and / or omitted, depending on the desired functionality.
[0040] [0040] UE 115 can comprise and / or be mentioned as a device, a mobile device, a wireless device, a mobile terminal, a terminal, a mobile station (MS), a SUPL-Enabled Terminal (SET) or by some other name. In addition, TIE 105 can correspond to a cell phone, smartphone, laptop, tablet, personal data assistant (PDA), tracking device, navigation device, Internet of Things (ToT) device, or some other portable or mobile device . Typically, although not necessarily, the TIE 105 can support wireless communication using one or more RATsS such as using GSM, code division multiple access (CDMA), broadband CDMA (WCDMA), LTE, high speed packet data ( HRPD), IEEE 802.11 WiFi (also referred to as Wi-Fi), Bluetooth (BT), Worldwide Interoperability for Microwave Access (WiMAX), New Radio 5G (NR) (for example, using NG-RAN 135 and 5GCN 140) , etc. The TIE 105 can also support wireless communication using a WLAN that can connect to other networks (for example, the Internet) using a digital Subscriber Line (DSL) or packet cable, for example. the use of one or more of these RATs may allow the UE 105 to communicate with an external customer 130 (for example, through elements of 5GCN 140 not shown in figure 1, or possibly through a Gateway Mobile Location Center (GMLC ) 125) and / or allow external customer 130 to receive location information in relation to UE 105 (for example, through GMLC 125).
[0041] [0041] UE 105 may include a single entity or may include multiple entities as in a personal area network where a user can employ 1/0 audio, video and / or data devices and / or body sensors and a modem without separate wire or cable. An estimate of a UE 105 location can be referred to as a location, location estimate, location fixing, fixing, position, position estimating or position fixing and can be geodesic, thereby providing location coordinates for the UE 105 (e.g. latitude and longitude) that may or may not include an altitude component (e.g., height above sea level, height above or depth below ground level, floor level, or basement level). Alternatively, a location of the UE 105 can be expressed as a civic location (for example, as a postal address or the designation of a small point or area in a building such as a specific floor or room). A UE 105 location can also be expressed as an area or volume (geodetic or civically defined) in which the UE 105 is expected to be located with some probability or level of confidence (for example, 67%, 95% etc.). A location of UE 105 can also be a relative location comprising, for example, a distance and direction or relative X, Y (and Z) coordinates defined in relation to some origin in a known location that can be defined in geodetic terms, in terms civic, or by reference to a point, area or volume indicated on a map, floor plan or building plan. In the description contained in the present invention, the use of the term localization may comprise any of these variants unless otherwise indicated. When computing the location of a UE, it is common to resolve local x, y and possibly z coordinates and then, if necessary, convert the local coordinates to absolute (for example, for latitude, longitude and altitude above or below average sea level).
[0042] [0042] Base stations (BSs) in NG-RAN 135 shown in figure 1 comprise gNBs, and 110-2 (collectively and generically referred to in the present invention as gNBs 110). Pairs of gNBs 110 on NG-RAN 135 can be connected to each other - for example, directly as shown in figure 1 or indirectly via other gNBs 110. Access to the 5G network is provided to the UE 105 via wireless communication between the UE 105 and one or more of the gNBs 110, which can provide wireless communication access to the 5GCN 140 on behalf of the UER 105 using 5GNR. NR 5G radio access can also be referred to as NR radio access or 5G radio access. In figure 1, gNB in service for UE 105 is assumed to be gNB 110-1, although other gNBs (for example, gNB 110-2) may act as a gNB in service if UE 105 moves to another location or can act as a secondary gNB to provide additional transmission capacity and bandwidth for UE 105.
[0043] [0043] Base stations (BSs) on the NG-RAN 135 shown in figure 1 can also or, instead, include a next generation developed Node B, also referred to as an ng-eNB, 114. ng-eNB 114 can be connected to one or more gNBs 110 in NG-RAN 135 - for example, directly or indirectly through other gNBs 110 and / or other ng- eNBs. An ng-eNB 114 can provide LTE wireless access and / or developed LTE wireless (eLTE) access to UE 105. Some 110 gNBs (for example, oNB 110-2) and / or ng-eNB 114 in figure 1 can be configured to function as positioning beacons only that can transmit signals (for example, PRS signals) and / or can broadcast assistive data to aid positioning of UE 105 but may not receive signals from UE 105 or other UEs . It is observed that although only one ng-eNBs 114 is shown in figure 1, some modalities may include multiple ng-eNBs 114.
[0044] [0044] Communication system 100 may also include one or more WLANs 116 that can connect to a Non-3GPP (N3IWF) 150 Function on the 5GCN 150 (for example, in the case of an untrusted WLAN 116). For example, WLAN 116 can support IEEE WiFi access
[0045] [0045] As mentioned in the present invention, access nodes can comprise any of a variety of network entities enabling communication between the UE 105 and the AMF 115. This may include gNBs 110, ng-eNB 114, WLAN 116 and / or others types of cellular base stations. However, access nodes providing the functionality described in the present invention may additionally or alternatively include entities that enable communications for any of a variety of RATs not shown in Figure 1, which may include non-cellular technologies. Accordingly, the term "access node," as used in the embodiments described in the present invention below, may include, but is not necessarily limited to, a gNB 110, ng-eNB 114 or WLAN 116.
[0046] [0046] As will be discussed in more detail below, in some modalities, an access node, such as a gNB 110, ng-eNB 114 or WLAN 116 (individually or in combination with other modules / units of the communication system 100), can be configured to, in response to receiving a request for location information for multiple RATs from LMF 120, take measurements for one of the multiple RATs (for example, measurements from UE 105) and / or obtain measurements from UE 105 which are transferred to the access node using one or more of the multiple RATs. As noted, although figure 1 shows access nodes 110, 114 and 116 configured to communicate according to 5GNR, LTE and WiFi communication protocols, respectively, access nodes configured to communicate according to other communication protocols can be used , such as a Node B using a WCDMA protocol for a UMTS terrestrial radio access network (UTRAN), an eNB using an LTE protocol for a developed UTRAN (E-UTRAN) or a BT beacon using a Bluetooth protocol for a WLAN . For example, in a developed 4G Package System (EPS) providing wireless LTE access for UE 105, an RAN may comprise an E-UTRAN, which may comprise base stations comprising eNBs supporting LTE wireless access. An EPS core network can comprise a developed packet core (EPC). An EPS can then comprise an E-UTRAN plus EPC, where the E-UTRAN corresponds to NG-RAN 135 and the EPC corresponds to 5GCN 140 in figure 1. The methods and techniques described in the present invention for positioning UE 105 using Common or generic positioning may apply to such other networks.
[0047] [0047] The goNBs 110 and ng-eNB 114 can communicate with an AMF 115, which, for positioning functionality, communicates with an LMF 120. The AMF 115 can support mobility of the UE 105, including cell change and UE handover 105 from an access node 110, 115 or 116 of a first RAT to an access node 110, 114 or 116 of a second RAT. The AMF 115 can also participate in supporting a signaling connection to the UE 105 and possibly voice and data bearers to the UE
[0048] [0048] The Gateway Mobile Location Center (GMLC) 125 can support a location request for UE 105 received from an external customer 130 and can issue such a location request to AMF 115 for issuance by AMF 115 to LMF 120 or you can issue the location request directly to LMF 120. A location response from LMF 120 (For example, containing a location estimate for UE 105) can similarly be returned to GMLC 125 directly or via AMF 115, and GMLC 125 can then return the location response (for example, containing the location estimate) to external client 130. GMLC 125 is shown connected to both AMF 115 and LMF
[0049] [0049] As further illustrated in figure 1, LMF 120 can communicate with gNBs 110 and / or ng- eNB 114 using the NRPPa protocol (which can also be referred to as NPPa). NRPPa can be the same as, similar to, or an extension of the LPPa protocol, with NRPPa messages being transferred between an oNB 110 and LMF 120 and / or between an ng-eNB 114 and LMF 120, through AMF 115 As further illustrated in figure 1, LMF 120 and UE 105 can communicate using the LPP protocol. LMF 120 and UE 105 can also or instead communicate using an NPP protocol, which can be the same as, similar to, or an LPP extension. Here, LPP and / or NPP messages can be transferred between UE 105 and LMF 120 via AMF 115 and a gNB in service 110-1 or ng-eNB in service 114 to UE 105. For example, LPP messages and / or NPP can be transferred between LMF 120 and AMF 115 using messages for service-based operations (for example, based on the Hypertext Transfer Protocol (HTTP)) and can be transferred between AMF 115 and UE 105 using a 5G NAS protocol. The LPP and / or NPP protocol can be used to support UE 105 positioning using UE-assisted and / or UE-based positioning methods such as A-GNSS, RTK, OTDOA and / or ECID. The NRPPa protocol can be used to support UE 105 positioning using network-based positioning methods such as ECID (for example, when used with measurements obtained by a gNB 110 or ng-eNB 114) and / or can be used by LMF 120 to obtain information related to the location from 9NBs 110 and / or ng-eNB 114, as parameters defining PRS transmission from 9gNBs 110 and / or ng-eNB 114.
[0050] [0050] In the case of UE 105 access to WLAN 116, LMF 120 can use NRPPa and / or LPP / NPP to obtain an UE 105 location in a similar way to that just described for UE 105 access to a gNB 110 or ng-eNB 114. In this way, NRPPa messages can be transferred between a WLAN 116 and LMF 120, through AMF 115 and N3IWF 150 to support network-based positioning of UE 105 and / or transfer of other location information from from WLAN 116 to LMF 120. Alternatively, NRPPa messages can be transferred between N3IWF 150 and LMF 120, via AMF 115, to support network-based positioning of UE 105 based on information related to location and / or location measurements known or accessible to N3IWF 150 and transferred from N3IWF 150 to LMF 120 using NRPPa. Similarly, LPP and / or NPP messages can be transferred between UE 105 and LMF 120 via AMF 115, N3IWF 150 and WLAN in service 116 to UE 105 to support UE-assisted or UE-based positioning of UE 105 by LMF 120.
[0051] [0051] With an EU-assisted positioning method, the UE 105 can obtain location measurements and send the measurements to a location server (eg LMF 120) for computing a location estimate to UE 105. For example, location measurements can include one or more of an Received Signal Strength Indication (RSSI), round trip signal propagation time (RTT), reference signal time difference (RSTD), arrival time (TO A), Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), Receive-Transmission Time Difference (Rx-Tx), Arrival Angle (AO A), Departure Angle (AOD) or Time advance (TA) for 9NBs 110, ng-eNB 114 and / or one or more access points for WLAN 116. Location measurements can also or instead include GNSS pseudo-reach measurements, GNSS code phase and / or GNSS carrier phase for SVs 190. With an EU-based positioning method, the UE 1 05 can obtain location measurements (for example, which can be the same as or similar to location measurements for an EU-assisted position method) and can additionally compute an UE 105 location (for example, with the help of assistance data received from a location server such as LMF 120 or broadcast by gNBs 110, ng-eNB 114 or WLAN 116). With a network-based positioning method, one or more base stations (for example, gNBs 110 and / or ng-eNB 114), one or more APs (for example, on WLAN 116) or N3IWF 150 can obtain location measurements ( for example, measurements from RSSI, RTT, RSRP, RSRQ, AOA or TOA) for signals transmitted by UE 105, or by an AP in WLAN 116 in the case of N3IWF 150, and you can send the measurements to a location server (for example , LMF 120) for computing a location estimate for UE 105.
[0052] [0052] Information provided by gNBs 110 and / or ng-eNB 114 for LMF 120 using NRPPa may include configuration and timing information for transmission of PRS and location coordinates. The LMF 120 can then provide some or all of this information to the UE 105 as assistance data in an LPP message and / or
[0053] [0053] An LPP or NPP message sent from the LMF 120 to the UE 105 can instruct the UE 105 to do any of a variety of things, depending on the desired functionality. For example, the LPP or NPP message could contain an instruction for UE 105 to obtain measurements for GNSS (or A-GNSS), WLAN, OTDOA and / or ECID (or some other position method). In the case of OTDOA, the LPP or NPP message can instruct the UE 105 to obtain one or more measurements (for example, RSTD measurements) of PRS signals transmitted in specific cells supported by specific 110 and / or ng-eNB 114 gNBs (or supported by some other type of base station such as an eNB or WiFi AP). An RSTD measurement can comprise the difference in the arrival times at UE 105 of a signal (for example, a PRS signal) transmitted or broadcast by one gNB 110 and a similar signal transmitted by another gNB 110. The UE 105 can send the measurements back to LMF 120 in an LPP or NPP message (for example, within an S5GNAS message) via gNB in service 110-l1 (or ng-eNB in service 114) and AMF 115.
[0054] [0054] As noted, although communication system 100 is described in relation to 5G technology, communication system 100 can be implemented to support other communication technologies, such as GSM, WCDMA, LTE etc. which are used to support and interact with mobile devices such as the UE 105 (for example, to implement voice, data, positioning and other features). In some of these modes, the 5GCN 140 can be configured to control different air interfaces.
[0055] [0055] To support certain positioning methods like OTDOA and transmission or PRS or other signals used for positioning an EGE 105, base stations can be synchronized. In a synchronized network, the transmission timing of gNBs 110 can be synchronized so that each gNB 110 has the same transmission timing as gNB 110 alternating at a high level of accuracy - for example, 50 nanoseconds or less. Alternatively, gNBs 110 can be synchronized to a radio frame or subframe level so that each gNB 110 transmits a radio frame or subframe for the same length of time as alternating gNB 110 (for example, so that each gNB 110 starts and finish transmitting a radio frame or subframe at almost exactly the same times as alternate gNB 110), but it does not necessarily maintain the same counters or numbering for radio frames or subframes. For example, when a gNB 110 is transmitting a subframe or radio frame with a counter or zero number (which may be the first radio frame or subframe in some periodically repeated sequence of radio frames or subframes), another 9gNB 110 may be transmitting a radio frame or subframe with a different number or counter such as one, ten, one hundred, etc.
[0056] [0056] The timing of the transmission timing of ng-eNBs 114 on NG-RAN 135 can be supported in a similar way to the synchronization of oNBs 110, although since n-eBNs 114 can typically use a different frequency for 110 gNBs ( to avoid interference), an ng- eNB 114 may not always be synchronized with gNBs 110. Synchronization of gNBs 110 and ng-eNBs 114 can be achieved using a GPS receiver or a GNSS receiver on each g9gNB 110 and ng-eNB 114 or otherwise using the IEEE 1588 Precision Time Protocol.
[0057] [0057] In the case of network-based ECID positioning, the modalities can use a generic procedure supported by NRPPa for UE access using NR (via a gNB 110), LTE (via a ng-eNB 114) or WiFi (via a Trusted or untrusted WLAN 116). The generic procedure is shown in figure 2, in the case of communication system 100, which shows a signaling flow for network-based ECID positioning and includes a target UE 105, a service access node (AN) 205 for the UE and an
[0058] [0058] For figure 2, it is assumed that LMF 120 needs to obtain a location of UE 105, for example, due to the receipt of a location request for UE 105 from another entity. For example, LMF 120 may receive a location request for UE 105 from AMF 115, where AMF 115 received a location request from UE 105 or GMLC 125, and where GMLC 125 may have received the request location from external client 130. Alternatively, LMF 120 can receive a location request for UE 105 directly from GMLC 125, where GMLC 125 may have received location request from external client 130. LMF 120 you can then perform the procedure shown in figure 2 to obtain or help obtain the requested location for the UE
[0059] [0059] At stage 210 in figure 2, LMF 120 sends an ECID NRPPa Measurement Initiation Request to OO in service 205, through AMF in service 115 to UE 105 (not shown in figure 2), to request measurements ECID from AN 205 to UE 105. The LMF 120 can request measurements applicable to multiple RATs, such as NR access, LTE access and / or WiFi access, for example. Table 1 below shows which measurements can be ordered. Measurements can be requested only once (referred to as “on demand”) or after certain triggered or periodic events (referred to as “periodic or triggered”).
[0060] [0060] In stage 220, optionally (for example, if requested in stage 1 for location on demand), the in service AN 205 requests and obtains measurements from UE 105, where UE 105 obtains measurements for downlink signals (DL ) received from the NA in service 205 and / or from neighboring NAs. Table 2 below shows which measurements can be requested and obtained. Neighboring NAs can be for the same RAT as the NA in service 205 and / or for other RATs. Stage 220 can be supported using a radio Resource Control (RRC) protocol for LTE or NR access by UE 105 (for example, when AN 205 is a gNB 110 or ng-eNB 114, respectively) or using an IEEE protocol 802.11 for WiFi access when AN 205 is a trusted WLAN 116. In the case of UE 105 accessing an untrusted WLAN 116 where AN 205 is an N3IWF (eg NWIWF 150), AN 205 can request and obtain measurements from UE 105 at stage 220 for sending a request to untrusted WLAN 116 which can then send a request to UE 105 (for example, using an IEEE protocol
[0061] [0061] In stage 230, optionally (for example, if requested in stage 1 for location on demand), the in-service AN 205 obtains measurements for uplink (UL) signals received from UE 105. The additional description below for Table 2 shows which measurements can be obtained. When AN 205 is a gNB 110, ng-eNB 114 or reliable WLAN 116, the AN 205 can obtain measurements directly from UL signals received from UE 105. When AN 205 is an N3IWF (for example, N31IWF 150), the AN 205 can request and obtain measurements from an untrusted WLAN 116 at stage 230, where untrusted WLAN 116 takes measurements of UL signals received from UE 105 and returns the measurements to AN 205.
[0062] [0062] At stage 240, the AN in service 205 returns any measurements obtained at stage 220 and / or stage 230 to LMF 120 in an ECID NRPPa Measurement Initiation Response. The additional description below for Table 2 shows which measurements can be returned. For periodic or triggered location, the in-service AN 205 may return an ECID NRPPa Measurement Initiation Responses containing no measurements at stage 240.
[0063] [0063] At stage 250, LMF 120 can determine a location for UE 105 using any measurements received at stage 240 (and possibly using other measurements obtained by LMF 120 using other procedures not shown in figure 2).
[0064] [0064] In stages 260-290, for events in which a periodic or triggered location request is sent at stage 210, the in service 205 can repeat the functionality of stages 220-240 one or more times in stages 260-280 and LMF 120 can determine a new UE location for each repetition in stage 290. In that case, the AN 205 would normally obtain measurements for at least one of stages 260 and 270 and can return the measurements to LMF 120 by sending an Initiation Report from ECID NRPPa measurement containing the measurements.
[0065] [0065] Table 1 shows which measurements can be requested by LMF 120 at stage 210. Measurements can be requested by including one or more of the Information Elements (IEs) shown in Table 1 in the ECID NRPPa Measurement Initiation Request submitted on stage 210. The LMF 120 can include any combination of the IEs shown in Table 1 and, for each IE included, can indicate a request for any of the measurements shown in the second column. For example, if LMF 120 requires measurements obtained by UE 105 as in stage 220 or 260 in figure 2 for an NR RAT, the LMF 120 may include the “EU NR measurements” IE shown in Table 1 in the ECID Measurement Initiation Request and you can indicate in that IE measurements of one or more of RTT, RSRP, RSRQO, AO A, AOD, Rx-Tx, RSTD or TO A. Although the LMF 120 may not know the RAT in service for the target UE (for example, if the RAT in service is NR, LTE or WiFi), the LMF 120 can request measurements applicable to some or all RATs and the in service AN 205 can then obtain and return only those measurements supported by AN 205, as described below for Table two.
[0066] [0066] The measurements shown in lines 2-4 of Table 1 can be obtained by AN 205 at stage 230 and / or at stage 270 by measuring (or obtaining measurements from another entity) UL signals transmitted by UE 105. The measurement shown lines 5-7 of Table 1 can be obtained by UE 105 at stage 220 and / or stage 260 by measuring DL signals transmitted by an AN in service 205 and / or by other ANs for the same RAT and / or for other RATs . Possible Measurements Element requested information (IE) by LMF 120 gNB RTT, TA, RSSI, AOA, Rx-Tx measurements ng-eNB RTT measurements, TA, RSSI, AOA, Rx-Tx WLAN RTT measurements, RSSI NR EU RTT measurements, RSRP, RSRQO, AOA, AOD, Rx-Tx, RSTD, TOA LTE UE RTT measurements, RSRP, RSRQO, Rx-Tx, RSTD, TOA UE RTT measurements, RSSI Table 1
[0067] [0067] Table 2 shows which measurements can be obtained by AN 205 in stages 220 and 230 (and stages 260 and 270, when applicable) and returned to LMF 120 in stage 240 (and stage 280). Measurements are conditional on the type of RAT supported by the AN in service 205 with the three columns to the right of Table 2 showing which IEs and measurements can be obtained and returned for each RAT (via a “Yes” entry for measurements that can be returned and a “No” entry for measurements that cannot be returned). For the example ECID procedure described here, each of the types of measurements obtained by TIE 105 (shown in the last three lines of Table 2) can be obtained and returned by AN 205 regardless of the RAT supported by AN
[0068] [0068] The generic procedure, messages and parameters described above and illustrated in figure 2 and Tables 1-2 enable an LMF 120 to request and obtain ECID measurements for any RAT in service for the target UE
[0069] [0069] In the case of EU-based or EU-aided OTDOA positioning, a generic procedure can be supported by LPP and / or NPP for UE access using NR (for example, via a gNB 110), LTE (for example, via an ng- eNB 114) or WiFi (for example, via a trusted or untrusted WLAN 116). A modality of such a generic procedure is shown in Figure 3, in the case of communication system 100, which shows a signaling flow for OTDOA positioning based on UE or assisted by UE and includes a target UE 105, three access nodes (ANl 205 -1, AN2 205-2 and AN3 205-3, collectively and generically referred to here as access nodes, or ANS, 205) and an LMF
[0070] [0070] With respect to figure 2, it is assumed for figure 3 that LMF 120 needs to obtain a location of UE 105, for example, due to the receipt of a location request for UE 105 from another entity as described previously for the figure 2 and that LMF 120 performs the procedure shown in figure 3 to obtain or help obtain the requested location for UE 105.
[0071] [0071] At stage 305 in figure 3, any time before stage 330, LMF 120 can send an OTDOA NRPPa Information Request to ANl 205-1 to obtain information from ANl 205-1 related to one or more signals (for example, PRS, TRS or CRS) broadcast from ANl 205-1 if AN1l 205-1 is a gNB 110 or ng-eNB
[0072] [0072] At stage 310, ANl 205-l1l returns information to LMF 120 in an OTDOA NRPPa Information Response for one or more signals (for example, PRS, TRS or CRS) broadcast from ANl 205-1 and as requested in stage 305. For example, AN1l 205-1 can provide information regarding PRS, TRS or CRS configurations supported by ANl 205-1. The configuration information for each broadcast signal could include,
[0073] [0073] At stage 315, LMF 120 can send an LPP / NPP Request Capabilities message to UE 105 to request UE 105 positioning capabilities as applicable to LPP / NPP.
[0074] [0074] At stage 320, UE 105 returns its positioning capabilities to LMF 120 in an LPP / NPP Provisioning Capabilities message. For example, capabilities can indicate the position methods supported by the UE 105, the measurements for each supported position method that are supported by the UE 105, the types of assistance data supported by the UE 105 for each supported position method and the RATs supported by the UE
[0075] [0075] At stage 325, based on the positioning capabilities of UE 105 obtained at stage 320 and other information such as the RATs supported by the LMF 120 Public Terrestrial Mobile Network (PLMN) operator in the vicinity of UE 105, LMF 120 determines one or more position methods to be used to locate UE 105. In this example, position methods include UE-based OTDOA or auxiliary by generic UE. LMF 120 then selects a reference cell (or cells) and neighboring cells for OTDOA. The reference cell (s) can correspond to a cell in current or previous service for UE 105 and neighboring cells can be other cells close to UE 105 (for example, close to a cell in current service) or earlier for UE 105). The reference and neighboring cells can all be for the same RAT or they can be for different RATs - for example, LTE and NR. The reference cell can be supported by an access node (for example, AN1 205-1) and the neighboring cells can be supported by other access nodes (for example, AN2 205-2 and AN3 205-3).
[0076] [0076] At stage 330, LMF 120 sends assistance data to UE 105 in an LPP / NPP Provision Assistance Data message. In this example, assistance data includes information for one or more broadcast signals for each of the reference and neighboring cells selected in stage 325 and possibly other information for neighboring and reference cells such as cell timing, differences in cell timing (for example , between a reference cell and a neighboring cell) and / or cell antenna location coordinates. For example, the information may comprise configuration information PRS, TRS and / or CRS and possibly other information related to the cell or AN as obtained by LMF 120 from ANl 205-1 at stage 310 and at stages similar to stage 310 from other NAs. Alternatively, some or all of this information can already be configured on the LMF 120.
[0077] [0077] At stage 335, LMF 120 sends a request for location measurements or a location estimate to UE 105 in an LPP / NPP Request Location Information message. When generic EU-assisted OTDOA is selected at stage 325, a request for RSTD OTDOA measurements is included. When generic EU-based OTDOA is selected at stage 325, a request for a location estimate is included.
[0078] [0078] At stage 340, AN1l 205-1, AN2 205-2 and AN3 205-3 broadcast signals across all their coverage areas that can be received by UE 105. For an AN 205 that is an oNB 110, ng-eNB 114 or an eNB, the signals can include a PRS, TRS, CRS or some other reference signal. For an AN 205 that is a WiFi AP, the signals may include an IEEE 802.11 beacon frame or some other IEEE 802.11 frame or frames.
[0079] [0079] In stage 345, UE 105 acquires and measures one or more of the broadcast signals in stage 340 and obtains one or more of the measurements requested in stage 335 in the case of UE-assisted OTDOA. Measurements can include RSTD measurements for OTDOA between a signal (for example,
[0080] [0080] At stage 350, if OTDOA based on generic UE was selected by LMF 120 at stage 325, UE 105 computes a location of UE 105 based on the measurements obtained at stage 345 and the assistance data received at stage 330. For example, if the assistance data includes the antenna locations for ANl 205-1, AN2 205-2, AN3 205-3 and other ANs and timing differences between the reference cell (s) and neighboring cells selected in the stage 325, UE 105 can obtain a location using multilateration based on known OTDOA techniques.
[0081] [0081] At stage 355, UE 105 returns the location estimate obtained at stage 350 or the measurements obtained at stage 345 to LMF 120 in an LPP / NPP provision Location Information message.
[0082] [0082] At stage 360, if OTDOA aided by generic UE was selected by LMF 120 at stage 325, LMF 120 computes a location for UE 105 based on measurements received at stage 355 and information configured at LMF 120 and / or received in stage 310 and similar stages for ANl 205-1, AN2 205-2, AN3 205-3 and other ANs. The LMF 120 can obtain a location using multilateration based on known OTDOA techniques.
[0083] [0083] To support the generic OTDOA procedure shown in figure 3, LMF 120 can provide assistance data for UE 105 at stage 330 for cells that belong to two or more different RATs. For example, cells may comprise cells for LTE access from an eNB, cells for LTE access from an ng-eNB (e.g., ng-eNB 114), and / or cells for NR access from an of a gNB (for example, gNB 110-1). A single reference cell can be provided by LMF 120 for UE 105 at stage 330 for which UE 105 obtains an RSTD measurement for each neighbor cell regardless of whether the neighbor cell is for the same RAT as the reference cell or is for a different RAT. In other embodiments, a different reference cell can be provided by LMF 120 for UE 105 at stage 330 for each RAT. For example, in these other modalities, LMF 120 can provide a first reference cell for NR, a second reference cell for LTE access from an ng-eNB, and a third reference cell for LTE access from an eNB, although in some embodiments only one of the second and third reference cells can be provided. The UE 105 can then obtain an RSTD for each reference cell only for neighboring cells that belong to the same RAT as the reference cell (for example, with LTE access to an ng-eNB considered to be the same RAT as LTE access to an eNB when only one of the second and third reference cells is provided).
[0084] [0084] As an example of these different reference cells, assume that cells C1, C2, .. CN belong to a first RAT and cells cl, c2, ... cM belong to a second RAT. If a reference cell is used for all RATs, LMF 120 can select cell Cl as the single reference cell and a UE 105 can obtain a separate RSTD measurement for each of cells C2, C2 ... CN, cl, c2, ... cM, where each separate RSTD measurement is an RSTD for one of these cells and the reference cell C1l. Conversely, when a reference cell is used for each RAT, LMF 120 can select cell Cl as the reference cell for the first RAT and cell cl as the reference cell for the second RAT, and a UE 105 can obtain a separate RSTD measurement for each of the C2, C2 ... CN cells with respect to the reference cell Cl and a separate RSTD measurement for each of the c2, c3, ... cM cells with respect to the reference cell cl.
[0085] [0085] Since the neighboring and OTDOA reference cells provided at stage 330 can include cells for different RATs, the UE 105 can obtain RSTD measurements at stage 345 regardless of which RAT the UE 105 is currently accessing. In addition, the UE 105 can continue to obtain RSTD measurements at stage 345 after a cell change or handover to a different RAT. In addition, if the UE 105 is accessing a RAT for which OTDA is not directly applicable as WiFi for WLAN 116, the UE 105 can still obtain RSTD measurements at stage 345 by periodically tuning to an NR and / or LTE frequency and measuring the timing of the reference cell (s) and neighboring cells provided by LMF 120 at stage 330.
[0086] [0086] As a person of ordinary skill in the art will recognize, ECID-assisted ECID positioning methods can also be modified according to the techniques described in the present invention, in a manner similar to the modalities described in figure 3. In particular, a location server can send a request to the UE for location measurements from the UE for a plurality of radio access types. The UE can then obtain location measurements of signals transmitted by at least one access node of the plurality of radio access types, returning to location measurements for the location server. The location server can then use those location measurements to determine a location for the UE. An example of an EU-assisted ECID positioning method is illustrated in figure 4.
[0087] [0087] Figure 4 shows a signaling flow illustrating a modality of an ECID positioning method aided by UE, in the case of the communication system
[0088] [0088] With respect to figures 2 and 3, it is assumed for figure 4 that LMF 120 needs to obtain a location of UE 105, for example, due to the receipt of a location request for UE 105 from another entity as previously described for figure 2 and that LMF 120 performs the procedure shown in figure 4 to obtain or help obtain the requested location for the UE
[0089] [0089] At stage 405, for example, LMF 120 may send an ECID NRPPa Information Request to ANl 205-1 to obtain information from ANl 205-1 related to one or more signals (for example, PRS, TRS or CRS) broadcast from ANl 205-1 if ANl 205-1 is a gNB 110 or ng-eNB 114. LMF 120 can select AN1 205-1 based on known proximity to target UE 105, for example, if LMF 120 is informed about the cell in initial service for UE 105 (for example, from the AMF in service). One or more broadcast signals can be reference signals used for ECID measurements.
[0090] [0090] In stage 410, AN1I 205-1 returns information to LMF 120 in an ECID NRPPa Information Response for one or more signals (for example, PRS, TRS or CRS) broadcast from ANl 205-1 and as requested at stage 405. For example, ANl 205-1 can provide information regarding PRS, TRS, or CRS configurations supported by AN1 205-1. The configuration information for each broadcast signal could include, for example, a signal identity (ID) (for example, a PRS ID), signal bandwidth, carrier frequency, encoding, a frequency shift, periodicity (for example, example, a starting subframe and number of subframes between consecutive occurrences of the broadcast signal), duration (for example, number of consecutive subframes used to broadcast the signal) and / or a muting pattern. ANl 205-l can also provide information related to ANl 205-1l or cells supported by ANl 205-1 as location coordinates of a cell antenna (or cell antennas), type (s) of antenna used by ANl 205 and / or cell timing information (for example, as cell timing relative to an absolute time such as GPS time or Coordinated Universal Time (UTC)). The LMF 120 can perform stages similar to stages 405 and 410 to obtain ECID information from AN2 205-2, AN3 205-3 and possibly other ANs (not shown in figure 4).
[0091] [0091] In one embodiment, the ECID NRPPa Information Request sent at stage 405 and the ECID NRPPa Information Responses returned at stage 410 can be replaced by an OTDOA NRPPa Information Request and an OTDOA NRPPA Information Response respectively, ( for example as used for stages 305 and 310 in figure 3). This modality can take advantage of information used by an UE 105 for positioning
[0092] [0092] At stage 415, LMF 120 can send an LPP / NPP Request Capabilities message to UE 105 to request UE 105 positioning capabilities as applicable to LPP / NPP.
[0093] [0093] At stage 420, the UE 105 returns its positioning capabilities to the LMF 120 in an LPP / NPP Provisioning Capabilities message. For example, capabilities can indicate the position methods supported by the UE 105, the measurements for each supported position method that are supported by the UE 105, the types of assistance data supported by the UE 105 for each supported position method and the RATs supported by the UE
[0094] [0094] In stages 425, based on the UE 105 positioning capabilities obtained in stage 420 and other information such as the RATs supported by the LMF 120 PLMN operator in the vicinity of the UE 105, the LMF 120 determines one or more positioning methods to be used to locate UE 105. In this example, position methods include ECID based on UE or aided by generic UE.
[0095] [0095] Optionally, at stage 430, LMF 120 can send assistance data to UE 105 in an LPP / NPP Provision Assistance Data message. In this example, assistance data may include information for one or more broadcast signals by a cell in current or previous service for UE 105 and / or one or more neighboring cells in the vicinity of UE 105. For example, the information may comprise configuration information PRS, TRS and / or CRS and / or other information related to cell or AN (for example, as cell antenna coordinates) as obtained by LMF 120 from AN1l 205-l1l in stage 410 and in stages similar to stage 410 from other NAs. Alternatively, some or all of this information can already be configured on LMF 120. In some modalities, stage 430 does not occur and instead UE 105 can obtain information regarding broadcast signals from a cell in service and neighboring cells and / or others information for a cell in service and neighboring cells (for example, as cell antenna coordinates) from the AN1 205-1 in service (for example, from information broadcast by AN1l 205-1 in System Information Blocks ( SIBs) or from information sent point by point by ANl 205-1 to UE 105, using RRC, for example).
[0096] [0096] At stage 435, LMF 120 sends a request for location measurements or a request for a location estimate to UE 105 in an LPP / NPP Request Location Information message. When generic EU-assisted ECID is selected at stage 425, LMF 120 can request measurements for one or more of RSSI, RTT, RSTD, RSRP, RSRQ, Rx-Tx, AO A, AOD, and / or TA. These measurements can be ordered separately for each of one or more different RATs. For example, LMF 120 may request a combination of measurements (between RSSI, RTT, RSTD, RSRP, RSRQ, Rx-Tx, AO A, AOD, and / or TA) for NR access, another combination of measurements for access to LTE for an EPS and / or a 5GCN (which can be the same or different to the combination for NR access), a third combination of measurements for WiFi access (which can also be the same or different to the combination (s) for NR and / or LTE access) and possibly a fourth combination of measurements for LTE access to any of 5GCN 140 or an EPS is not included for the second combination in the case of LTE access to EPS and LTE access to 5GCN 140 be treated as being different RATs. When generic EU-based ECID is selected at stage 425, a request for a location estimate is included instead of a request for ECID measurements.
[0097] [0097] In stage 440, AN1l 205-1, AN2 205-2 and AN3 205-3 broadcast signals across all of their coverage areas that can be received by UE 105. For an AN 205 that is an oNB 110, ng-eNB 114 or an eNB, the signals can include a PRS, TRS, CRS or some other reference signal. For an AN 205 that is a WiFi AP, the signals may include an IEEE 802.11 beacon frame or some other IEEE 802.11 frame or frames.
[0098] [0098] In stage 445, UE 105 acquires and measures one or more of the broadcast signals in stage 440 and obtains one or more of the measurements requested in stage 435 in the case of EU-assisted ECID. Typically, the UE 105 can obtain requested measurements for RAT (s) that comprise the
[0099] [0099] At stage 450, if ECID based on generic UE was selected by LMF 120 at stage 425, UE 105 computes a location of UE 105 based on the measurements obtained at stage 445 and the assistance data received at stage 430. For For example, if assistance data includes antenna locations for ANl 205-1, AN2 205-2, AN3 205-3 and other ANs, the UE 105 can obtain a location using triangulation, multilateration and / or other techniques, as applicable measurements obtained at stage 445.
[0100] [0100] At stage 455, UE 105 returns the location estimate obtained at stage 450 or the measurements obtained at stage 445 to LMF 120 in an LPP / NPP Provision Location information message.
[0101] [0101] At stage 460, if generic EU-assisted ECID was selected by LMF 120 at stage 425, LMF 120 computes a location for UE 105 based on measurements received at stage 455 and information configured at LMF 120 and / or received in stage 410 and similar stages for ANl 205-1, AN2 205-2, AN3 205-3 and other ANs. The LMF 120 can obtain a location using triangulation, multilateration and / or other techniques, as applicable to measurements received at stage 455 (for example, based on known ECID techniques).
[0102] [0102] To support the generic ECID procedure shown in figure 4, LMF 120 can provide assistance data for UE 105 at stage 430 for cells and / or APs supporting two or more different RATs. For example, cells may comprise cells for LTE access from an eNB, cells for LTE access from an ng-eNB (e.g., ng-eNB 114), and / or cells for NR access from an of an oNB (for example, gNB 110-1). In addition, assistance data can be provided at stage 430 for WiFi APs. LMF 120 may also or instead request measurements from UE 105 at stage 435 for two or more different RATs in the case of generic EU-assisted ECID. The LMF 120 may not initially know the cell in current service (or WiFi AP in service) for UE 105 or the RAT (s) in current service (s) but for providing assistance data for multiple RATs in stage 430 and / or by requesting measurements for multiple RATs at stage 435, you may still be able to obtain measurements or a location estimate from UE 105 at stage 455, which can enable a UE 105 location to be obtained by LMF 120.
[0103] [0103] Figure 5 is a flow chart illustrating a method 500 of locating a UE (for example, UE 105) on a location server on a wireless network, according to one embodiment, which illustrates the functionality of a location according to aspects of the modalities described above and illustrated in figures 1-4. Thus, according to some modalities, the functionality of one or more blocks illustrated in figure 5 can be performed by an LMF 120, such as the LMF 120 of the communication system 100 in figure 1, or by an E-SMLC or SLP. And since a location server can comprise a computer system, a means of performing these functions can include software and / or hardware components of a computer system, such as the computer system illustrated in figure 9 and described in more detail below.
[0104] [0104] In block 510, the functionality includes sending, to a wireless entity, a first message comprising a request for a first set of location measurements to determine a location of the UE, where the first set of location measurements comprises - “ measurements of signals belonging to a plurality of RATs, where the plurality of RATs includes a RAT in service that serves the UE, and where whose RAT, of the plurality of RATs, comprises the RAT in service is unknown to the location server. As noted above, this can occur in certain circumstances, such as when a location session is initiated between the location server and a UE and / or AN when the UE is accessing a first RAT and when the UE subsequently accesses a second RAT during the localization session. The plurality of RATs can comprise any of a variety of RATs, including, for example, a fifth generation New Radio (NR) RAT (5G), a Long Term Evolution (LTE) RAT, an IEEE 802.11 WiFi RAT, a Bluetooth RAT or some combination thereof. The functionality performed in block 510 can be performed for UE-assisted, UE-based or network-based positioning, depending on the desired functionality. Therefore, in some respects, the functionality of block 510 may correspond to stage 210 of figure 2, stage 335 of figure 3 and / or stage 435 of figure 4.
[0105] [0105] For network-based ECID, for example, the wireless entity can comprise a first access node for the wireless network for the RAT in service. In such instances, the first access node may comprise a NodeB NR (oNB, for example, gNB 110) for a RAT NR, a developed Node B of the next generation (ng-eNB, for example, ng- eNB 114) for a RAT LTE, a wireless local area network (WLAN, for example, WLAN 116) for a TIEEE WiFi RAT
[0106] [0106] Means for performing the functionality in block 510 may comprise one or more components of a computer system, such as a bus 905, processing unit (s) 910, communication subsystem 930, working memory 935, operating system 940, application (s) 945 and / or other components of computer system 900 illustrated in figure 9 and described in more detail below.
[0107] [0107] In block 520, functionality includes receiving a second message from the wireless entity, where the second message comprises a second set of location measurements to determine the location of the UE, where the second set of location measurements comprises a subset of the first set of location measurements and where the second set of location measurements includes measurements of signals that belong to the RAT in service. For example, if the request for the first set of location measurements in block 510 includes a request for measurements using NR, LTE and WiFi, The second set of location measurements received in block 520 can include any one or only understand measurements using LTE . Again, the functionality performed on block 520 can be performed for UE-assisted, UE-based or network-based positioning, depending on the desired functionality. Therefore, in some respects, the functionality of block 520 may correspond to stage 240 and / or 280 in figure 2, stage 355 in figure 3, and / or stage 455 in figure 4.
[0108] [0108] In modalities where the wireless entity comprises a first wireless network access node for the RAT in service (for example, for network-based ECID), the first message and / or the second message may comprise messages for an NR A Positioning Protocol (NRPPa). In some instances, in these modalities, the first access node can make measurements of the UE (for example, as in stage 230 and / or 270 in figure 2). the second set of location measurements can then comprise location measurements, obtained by the first access node, of signals transmitted by the UE using the RAT in service. In some of these modalities, the location measurements obtained by the first access node may comprise at least one of the Received Signal Strength Indication (RSSI), Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ ), Round trip signal propagation time (RTT), Arrival Angle (AO A), Receive-Transmission Time Difference (Rx-Tx), or some combination thereof.
[0109] [0109] In modalities where the wireless entity comprises the UE (for example, for EU-assisted ECID or OTDOA), the first message and / or the second message may comprise messages for an LTE Positioning Protocol (LPP), a NR Positioning protocol (NPP) or both protocols. In these modalities, the UE can make measurements of signals transmitted by an access node to the wireless network to the RAT in service (for example, as in stage 345 in figure or stage 445 in figure 4). the second set of location measurements can then comprise location measurements obtained by the UE from signals transmitted by a first access node using the RAT in service. Here, the location measurements obtained by the UE can comprise at least one of the Received Signal Strength Indication (RSSI), Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), round-trip signal (RTT), Angle of Arrival (AO A), Angle of Departure (AOD), Difference in Time of Receipt- Transmission (Rx-Tx), Arrival time (TOA) or some combination thereof. In some of these modalities, the first access node may comprise a NodeB NR (gNB, for example, gNB 110) for a RAT NR, a developed Node B of the next generation (ng-eNB, for example, ng-eNB 114) for an LTE RAT, a wireless local area network (WLAN, for example, WLAN 116) for an IEEE 802.11 WiFi RAT, or a WLAN for a Bluetooth RAT. Additionally or alternatively, the first access node may comprise a gNB in service or an ng-eNB in service for the UE. In some of these modalities, the UE can make measurements of signals transmitted by the additional access nodes using the RAT in service (for example, described for OTDOA in figure 3, where the UE 105 can measure signals transmitted by an access node that supports a OTDOA reference cell and other access nodes that support neighboring OTDOA cells). The second set of location measurements can then comprise location measurements, obtained by the UE, of signals transmitted by a plurality of access nodes using the RAT in service. Here, the location measurements obtained by the UE can comprise at least one of an Arrival Time (TOA), a Reference Signal Time Difference (RSTD) or some combination thereof. In addition or otherwise, in these modalities (for example, as described for stage 445 in figure 4), the UE can obtain measurements of access nodes using a RAT or RATs other than the RAT in service of the first access node. In this way, the second set of location measurements may comprise location measurements, obtained by the UE, of signals transmitted by a plurality of access nodes using at least one of the plurality of RATs, where at least one of the plurality of RATs is different from RAT in service.
[0110] [0110] Means for performing the functionality in block 520 may comprise one or more components of a computer system, such as a bus 905, processing unit (s) 910, communication subsystem 930, working memory 935, operating system 940, application (s) 945 and / or other components of computer system 900 illustrated in figure 9 and described in more detail below.
[0111] [0111] The functionality in block 530 comprises determining a location of the UE based on the second set of location measurements. Again, the functionality performed here can be performed for an EU-assisted, EU-based or network-based positioning. Therefore, in some respects, the functionality of block 530 may correspond to stage 250 (and optionally stage 290) in figure 2, stage 360 in figure 3, and / or stage 460 in figure 4. Means for executing functionality in block 530 may comprise one or more components of a computer system, such as a 905 bus, processing unit (s) 910, working memory 935, operating system 940, application (s) 945, and / or other components of the computer system 900 illustrated in figure 9 and described in more detail below.
[0112] [0112] Figure 6 is a flowchart illustrating a method 600 of locating an UE (for example, UE 105) on an access node for a wireless network, according to one embodiment, which illustrates the functionality of a base station and / or other types of access nodes according to aspects of modalities described above and illustrated in figures 1-4. Thus, according to some modalities, the functionality of one or more blocks illustrated in figure 6 can be performed by an access node in service, such as gNB (for example, gNB 110), ng- andNB (for example, ng -eNB 114), WLAN (for example, WLAN 116), or N3IWF (for example, N3IWF 150) as in figure 1, by AN 205 of figure 2, or AN2 205-1 of figures 3 and 4. And since the access node can comprise a computer system, means for performing these functions can include software and / or hardware components of a computer system, such as the computer system illustrated in figure 9 and described in more detail below. In addition or alternatively, means for performing these functions may include software and / or hardware components of an access node, such as the access node illustrated in figure 10 and described in more detail below.
[0113] [0113] In block 610, the functionality includes receiving, from a location server (for example, LMF 120) on the wireless network, a first message comprising a request for a first set of location measurements to determine a location of the UE, where the first set of location measurements comprises measurement of signals that belong to a plurality of RATs, where the plurality of RATs comprise a RAT in service that serves the UE, where whose RAT, of the plurality of RATs, comprises the RAT in service is unknown to the location server, and where the access node is an RAT access node in service. The plurality of RATs can comprise any of a variety of RATs, including, for example, a new generation (5G) Radio RAT (NR), a long-term Evolution RAT (LTE), an IEEE 802.11 WiFi RAT, a Bluetooth RAT or some combination thereof. In some instances, the Access Node may comprise a NodeB NR (gNB) for a RAT NR, a Node B developed for the next generation (ng-eNB) for a RAT LTE, a wireless local area network (WLAN) for a IEEE 802.11 WiFi RAT, a WLAN for a Bluetooth RAT or a Non-3GPP interoperation function
[0114] [0114] Means for executing the functionality in block 610 may comprise one or more components of a computer system, such as a bus 905, processing unit (s) 910, communication subsystem 930, working memory 935, operating system 940, application (s) 945 and / or other components of computer system 900 illustrated in figure 9 and described in more detail below. Additionally or alternatively, means for performing functionality in block 610 may comprise one or more components of an access node, such as a bus 1005, processing unit (s) 1010, wireless communication interface 1030, memory 1060, network interface 1080 , and / or other components of the access node 1000 illustrated in figure 10 and described in more detail below.
[0115] [0115] In block 620, functionality includes obtaining a second set of location measurements to determine the location of the UE, where the second set of location measurements comprises a subset of the first set of location measurements, and where the second set of Location measurements include measurements of signals that belong to the RAT in service. The functionality performed on block 620 can be performed for network-based positioning. Therefore, in some respects, the functionality of block 620 may correspond to stages 220, 230, 260 and / or 270 in the figure
[0116] [0116] Again, depending on the desired functionality, the location information may include measurements made by the access node (for example, as in stages 230 and 270 in figure 2). Thus, according to some modalities, obtaining the second set of location measurements in block 620 may comprise obtaining a third set of location measurements of signals for the RAT in service transmitted by the UE and including, in the second set of measurements of location, oThe third set of location measurements. Here, according to some modalities, the third set of location measurements can comprise at least one of the Received Signal Strength Indication (RSSI), Received Reference Signal Power (RSRP), Received Reference Signal Quality (RSRQ ), Round trip signal propagation time (RTT), Arrival Angle (AO A), Receive-Transmission Time Difference (Rx-Tx) or some combination thereof.
[0117] [0117] In some modalities, the location information may include measurements made by the UE (for example, as in stages 220 and 260 in figure 2). Thus, according to some modalities, obtaining the second set of location measurements may comprise receiving, on the access node, location measurements, obtained by the UE, of signals transmitted by at least one access node using at least one of the plurality of RATs and including, in the second set of location measurements, the location measurements obtained by the UE. In such instances, at least one access node may comprise the access node and at least one of the plurality of RATs may comprise the RAT in service. Alternatively, at least one access node does not comprise the access node. In this case mentioned last, according to some modalities, at least one of the plurality of RATs may not understand the RAT in service. In some embodiments, obtaining measurements made by the UE by the access node may involve a request and response interaction between the access node and UE (for example, using an RRC protocol). Thus, according to some modalities, receiving the location measurements obtained by the UE at the access node can be in response to the sending, to the UE, of a request for the location measurements obtained by the UE. Additionally or alternatively, the location measurements obtained by the UE may comprise at least one of the Received Signal Strength Indication (RSSI), Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), round-trip signal propagation (RTT), Arrival Angle (AO A), Departure Angle (AOD), Receive-Transmission Time Difference (Rx-Tx), Reference signal time difference (RSTD), Arrival time (TOA) or some combination thereof.
[0118] [0118] Means for executing the functionality in block 620 may comprise one or more components of a computer system, such as a bus 905, processing unit (s) 910, communication subsystem 930, working memory 935, operating system 940,
[0119] [0119] In block 630, the functionality includes sending a second message to the location server, where the second message comprises the second set of location measurements. In some embodiments, the first message and the second message may comprise messages for an NR A Positioning Protocol (NRPPa). Again, the functionality performed on block 630 can be performed for network-based positioning. Thus, in some aspects, the functionality of block 630 may correspond to stages 240 and 280 of figure 2.
[0120] [0120] Means for performing the functionality in block 630 may comprise one or more components of a computer system, such as a bus 905, processing unit (s) 910, communication subsystem 930, working memory 935, operating system 940, application (s) 945 and / or other components of computer system 900 illustrated in figure 9 and described in more detail below. Additionally or alternatively, means for performing functionality in block 630 may comprise one or more components of an access node, such as a bus 1005, processing unit (s) 1010, wireless communication interface 1030, memory 1060, network interface 1080 , and / or other components of the access node 1000 illustrated in figure 10 and described in more detail below.
[0121] [0121] Figure 7 is a flow chart illustrating a method 700 in a UE (for example, UE 105) for providing location information, according to one modality, which illustrates the functionality of a UE according to aspects of described modalities above and illustrated in figures 1-4. Means for performing these functions may include software components and / or hardware from an UE 105, such as the UE 105 illustrated in figure 8 and described in more detail below.
[0122] [0122] In block 710, the functionality includes receiving, from a location server (for example, the LMF 120) on the wireless network, a first message comprising a request for a first set of location measurements to determine a location UE, where the first set of location measurements comprises “measurements of signals that belong to a plurality of RATs, where the plurality of RATs includes a RAT in service that serves the UE, and where whose RAT, of the plurality of RATs, comprises the RAT in service is unknown to the location server.
