description
The present invention relates to a communication system with two mobile radio communication devices, each with integrated subscriber identity modules for cooperative mobile radio communication over a mobile radio network with a network identification. The invention also relates to a corresponding mobile radio communication device and a method for cooperative communication via a mobile radio network.
Cellular communication devices with one or more SIM cards are increasingly being used in the loT (Internet of Things) area to network machines. Such devices make it possible to network not only machines, but also physical and virtual objects in general and let them work together through communication. Functions implemented with technologies of the "Internet of Things" allow interaction between humans and any electronic systems networked through them, as well as between the systems themselves. The aim of the Internet of Things is to automatically capture and link relevant information from the real world For this purpose, communication networks based on the 5G system architecture are increasingly being used, as outlined, for example, in the 3GPP TS 23.501 specification.
In the field of industrial automation and loT communication, failure safety is increasingly becoming a basic requirement. In the case of critical controls, the power supply is designed redundantly so that operation is guaranteed even if one power supply unit fails. With loT communication, in addition to the power supply, data transmission via the communication interface can also fail, for example if the radio link is shaded. Particularly in the field of factory automation and self-controlling systems, such as self-driving vehicles, there is a need for secure communication in order to prevent damage as much as possible in advance.
It is the object of the present invention to create a concept for fail-safe and highly available mobile radio communication which, when communicating from person-to-person, person-to-machine and / or machine-to-machine, enables communication with a low failure rate and high availability guaranteed.
In particular, it is the object of the present invention to provide a cellular communication device that ensures fail-safe and highly available cellular communication via cellular networks and network technologies, in particular network slices of a 5G system architecture.
This object is achieved by the features of the independent claims. The dependent claims relate to advantageous forms of further training.
The mobile radio communication devices and communication systems presented below can be of various types. The individual elements described can be implemented using software or hardware components and can be produced using various technologies. The individual components can include, for example, microprocessors, semiconductor chips, ASICs, signal processors, electro-optical circuits, integrated electrical circuits and / or passive components.
The mobile radio communication devices and mobile radio networks presented in the following can comprise various technologies and network standards, for example in accordance with the 5G system architecture. The 5G system architecture includes the concept of network slicing, i.e. the division of the communication network into individual pieces or slices or sub-networks. Network slicing is a form of virtual network architecture in which network architectures are partitioned into virtual elements that can be linked to one another (also via software). The concept of network slicing allows multiple virtual networks to be created on a common physical infrastructure. The virtual networks can then be adapted to the specific requirements of applications, services, devices, customers or operators. Each virtual network (network slice) comprises an independent set of logical network functions that support the requirements of the respective application.
Each of these virtual networks or network slices provides resources and network topology for a specific service and traffic that uses the corresponding segment. Functions such as speed, capacity, connectivity and coverage can be assigned to meet the special requirements of each application, but functional components can also be shared across different network slices. In addition, each network slice can be given management capabilities that can be controlled by the network operator or user depending on the application. The network slices can be managed and orchestrated independently.
The cellular networks described below can be based on 5G networks in accordance with the 5G system architecture. The service-oriented 5G network supports very different services with very different performance requirements. For example, 5G supports the three different service categories Enhanced Mobile Broadband (eMBB), massive machine type communication (mMTC, also known as loT, i.e. Internet of Things) and ultra-reliable communication with low latency (UR-LLC).
The mobile radio communication devices described below include mobile radio communication interfaces or simply referred to as communication interfaces, which perform a variety of tasks. A
Such a communication interface can include, for example, a processor that is responsible for carrying out the tasks described. The term "processor" refers to any device that can be used to process certain tasks (or blocks or steps). A processor can be a single processor or a multi-core processor or can contain a set of processors or can contain means for processing. A processor can handle software or firmware or applications etc.
According to a first aspect, the invention relates to a communication system for cooperative communication via a cellular network, the cellular network having a network identification, with: a first cellular communication device, having the following features: a first cellular communication interface for communication with the cellular network, wherein the first mobile radio communication interface has a first integrated subscriber identity module (iSIM: Integrated Subscriber Identity), the first integrated subscriber identity module being implemented as an embedded integrated circuit and permanently storing a first mobile radio subscriber identifier together with the network identification and a network address of the mobile radio network, wherein the first cellular subscriber identifier identifies the first integrated subscriber identity module in the cellular network; a first data memory which is set up to store first data for transmission to the cellular network; a first bus communication interface; a second mobile radio communication device, having the following features: a second mobile radio communication interface for communication with the mobile radio network, the second mobile radio communication interface having a second integrated subscriber identity module (ISIM: Integrated Subscriber Identity), the second integrated subscriber identity module being an embedded integrated circuit is implemented and permanently stores a second cellular subscriber identifier together with the network identification and the network address of the cellular network, the second cellular subscriber identifier identifying the second integrated subscriber identity module in the cellular network; a second data memory which is set up to store second data for transmission to the cellular network; a second bus communication interface, the second bus communication interface being connected to the first bus communication interface via a data bus; wherein the second mobile radio communication interface is designed to receive a network signal from the mobile radio communication network and to compare a signal strength of the received network signal with a threshold value, wherein the second mobile radio communication interface is further designed to provide the network identification when the threshold value is exceeded by the received network signal, read out the network address of the cellular network and the second cellular subscriber identifier from the second integrated subscriber identity module and send the second cellular subscriber identifier together with the network identification, the network address of the cellular network and the second data to the network address of the cellular network; and if the received network signal falls below the threshold value, to transmit the network address of the cellular network together with the network identification, the second data and the second cellular subscriber identifier to the second bus communication interface; wherein the second bus communication interface is designed to transmit the received network address of the mobile radio network together with the network identification, the second data and the second mobile radio subscriber identifier via the data bus to the first bus communication interface of the first mobile radio communication device; wherein the first mobile radio communication interface is designed to transmit the received second data together with the second mobile radio subscriber identifier and the network identification to the network address of the mobile radio network.
Such a mobile radio communication system ensures particularly secure and highly available communication due to the cooperative data transmission by the two mobile radio communication devices. If the radio signal from the second communication device is difficult to receive, for example because the second communication device is in the shaded position, the data can be transmitted via the bus communication interface to the first mobile radio communication device and through this via its mobile radio communication interface to the mobile radio network. The same applies to the opposite direction and to the design with more than two mobile radio communication devices. In the case of several mobile radio communication devices, the data can be forwarded, for example, via the respective bus communication interfaces to the communication device which receives the best network signal, and can be transmitted through this to the mobile radio network. This allows a particularly high availability of the data transmission to the cellular network. The cellular communication system thus allows fail-safe cellular communication and guarantees a low and high failure rate due to the cooperative communication among the cellular communication devices when communicating from person-to-person, person-to-machine and / or machine-to-machine Availability. In particular, the mobile radio communication system ensures fail-safe and highly available mobile radio communication via mobile radio networks and network technologies, in particular via network slices of the 5G system architecture, as described in this disclosure.
The data of the corresponding mobile radio communication device are identified by the respective subscriber identification of the mobile radio communication devices so that they can be assigned to the corresponding mobile radio subscriber in the mobile radio network at any time. This subscriber identifier is a unique identifier in the mobile radio network, for example an IMSI (International Mobile Subscriber Identity).
In an exemplary embodiment of the mobile radio communication system, the data bus connects the second bus communication interface while bypassing the mobile radio network with the first bus communication interface.
This achieves the advantage that the two mobile radio communication devices are directly connected via the two bus communication interfaces without first having to establish communication via the mobile radio network. This ensures high availability, since the communication path between the two communication devices has to bridge a shorter distance than the communication path in uplink and downlink via the cellular network. For example, the communication path between the two communication devices can be a sidelink communication path that implements a direct cellular communication link between the two communication devices, for example in accordance with the cellular radio standard 5G NR V2X (5G New Radio Vehicle-to-Anything). Instead of a cellular connection, however, a WLAN connection or a Bluetooth connection can also be implemented as a bus communication interface. Alternatively, the communication path between the two communication devices can also be, for example, wired, for example implemented as a USB connection or as a powerline connection. This can be useful if the communication devices are loT devices, e.g. loT sensors or loT actuators, which are not far from each other in the home network or in the factory and are to transmit different data, for example temperature, pressure, switch position, alignment of Machine components, control signals, etc.
In an exemplary embodiment of the cellular communication system, the second bus communication interface is designed to receive a master signal from the first bus communication interface, and in response to receiving the master signal to instruct the second cellular communication interface to transmit the network identification and the To interrupt the network address of the cellular network together with the second data and the second cellular subscriber identifier to the network address of the cellular network and the network identification and the network address of the cellular network together with the second data and the second cellular subscriber identifier only via the data bus to the first bus communication interface of the first cellular communication device.
This has the advantage that one of the two mobile radio communication devices can be set up as a communication master via which the mobile radio communication with the network is to take place. This master communication device can, for example, be equipped with particularly high resources for cellular communication or it can be set up where the radio channel to the cellular network is particularly good, for example on the roof of the house, while the other cellular communication devices are in other locations with poor radio reception can be set up. Your data can then be transmitted to the master communication device via the bus interface, for example via the house's powerline from the basement to the roof. The other mobile radio communication devices can then be set up in the basement, for example, where a lot of measurement data is available. Or the other mobile radio communication devices can be set up in a security area, where security-relevant data can be recorded which can be transmitted to the master communication device via the bus communication interface.
In an exemplary embodiment of the cellular communication system, the first cellular communication interface is designed to add the first cellular subscriber identifier together with the second cellular subscriber identifier and the network identification to the network address of the cellular network when sending the received second data.
This has the advantage that the cellular network knows from the received data on the one hand from which device these data originate, and on the other hand, which device has transmitted the data. The mobile radio network thus knows that there are or has been problems with the radio accessibility of the second mobile radio communication device via the mobile radio communication interface and can thus initiate suitable repair measures, for example changing the radio resources, for example by transmitting via a different radio channel, or informing a maintenance technician so that he can repair the second cellular communication device.
In an exemplary embodiment of the mobile radio communication system, the first mobile radio communication interface is designed to send the first data together with the first mobile radio subscriber identifier and the network identification to the network address of the mobile radio network in a first time interval; and the first mobile radio communication interface is designed to send the received second data together with the second mobile radio subscriber identifier and the network identification to the network address of the mobile radio network in a second time interval, the first time interval being different from the second time interval.
This has the advantage that the two communication devices transmit their data to the cellular network at different time intervals. The radio interface of the cellular network is thus used efficiently and there is no overload when two or more communication devices transmit their data, since this does not happen at the same time. Furthermore, the design of the communication system can thus be better planned and the system can work in a resource-efficient manner.
In an exemplary embodiment of the mobile radio communication system, the second bus communication interface is formed, the network identification and the received network address of the mobile radio network together with the second data and the second mobile radio subscriber identifier in the first time interval via the data bus to the first bus communication interface of the first mobile radio communication device.
This has the advantage that the two interfaces, mobile radio communication interface and bus communication interface, are used reciprocally and therefore particularly efficiently. While the cellular communication interface transmits the data of the first cellular communication device to the cellular network in the first time interval, the data of the second cellular communication device are transmitted to the first cellular communication device via the bus communication interface at the same time, i.e. in the first time interval. This means that both interfaces are used particularly efficiently.
In an exemplary embodiment of the cellular communication system, the second cellular communication interface is designed to send a registration request for registering the second cellular communication device in the cellular network to the network address of the cellular network when the threshold value is exceeded by the received network signal; and the second cellular communication interface is designed to send the registration request for registering the second cellular communication device in the cellular network via the second bus communication interface, the first bus communication interface and the first cellular communication interface to the network address of the received network signal when the received network signal falls below the threshold value Send out cellular network; and the first cellular communication interface is designed to transmit a confirmation of the cellular network to the registration request for registering the second cellular communication device in the cellular network via the first bus communication interface to the second bus communication interface of the second cellular communication device.
This achieves the advantage that the second mobile radio communication device can automatically register via its mobile radio communication interface in the network with a good connection to the network, while it can register itself in the network with a bad network connection via the first mobile radio communication device. The confirmation of the registration request is forwarded from the first mobile radio communication device to the second mobile radio communication device via the bus communication interface.
In an exemplary embodiment of the cellular communication system, the cellular communication system comprises a further cellular communication device, which is constructed analogously to the second cellular communication device, but does not have its own cellular communication interface to the cellular network, so that communication with the cellular network is via the bus communication interface is routed to the first or second mobile radio communication device and via its mobile radio communication interface to the mobile radio network.
This has the advantage that the further mobile radio communication device can be designed in a particularly cost-effective manner, since it does not require its own mobile radio communication interface and also does not require any protocols for communication with the mobile radio network via this interface. Instead, a simple communication protocol via the bus communication interface is sufficient, for example USB or Powerline or Bluetooth or WLAN. In this way, inexpensive mobile radio communication devices can be designed in the loT area, which, for example, can record a large number of different sensor data and transmit their measured values to the mobile radio network via a specially designed master mobile radio communication device. For example, sensors can be attached to each joint of a production robot, which record the exact position data of the robot and transmit it via the bus communication interfaces to a master cellular communication device, which then transmits this data to the cellular network via its cellular communication interface.
In an exemplary embodiment of the cellular communication system, the cellular network is a subnetwork of a 5G cellular network, wherein the first and the second cellular communication device are each loT communication devices, the first cellular subscriber identifier in the first integrated subscriber identity module using a first public cryptographic key is stored cryptographically encrypted, and wherein the second mobile subscriber identification is stored cryptographically encrypted in the second integrated subscriber identity module using a second public cryptographic key, wherein the first public cryptographic key and the second public cryptographic key are assigned to the cellular network.
This offers the technical advantage that the two integrated subscriber identity modules or eSIM modules can be used in 5G communication networks, in particular network slices, and due to the cooperation of the two communication devices with high availability and low susceptibility to errors, they transmit their data to the cellular network. The advantages of the 5G system architecture can thus be exploited, i.e. the virtual network architecture on a common physical infrastructure, the specific adaptation to the requirements of applications, services, devices, customers or operators, the support of logical network functions, the application-specific assignment of functions such as speed , Capacity, connectivity and network coverage to meet the special requirements of each application, the shared use of functional components across different network slices, etc. Due to the cooperative use of the two or more mobile communication devices, the reliability and availability in the Increase 5G communication network significantly.
According to a second aspect, the invention relates to a second mobile radio communication device for cooperative communication via a mobile radio network, the mobile radio network having a network identification, wherein
The second mobile radio communication device has the following features: a second mobile radio communication interface for communication with the mobile radio network, the second mobile radio communication interface having a second integrated subscriber identity module (iSIM: Integrated Subscriber Identity), the second integrated subscriber identity module being an embedded one Integrated circuit is implemented and permanently stores a second mobile radio subscriber identifier together with the network identification and the network address of the mobile radio network, the second mobile radio subscriber identifier identifying the second integrated subscriber identity module in the mobile radio network; a second data memory which is set up to store second data for transmission to the cellular network; a second bus communication interface, the second bus communication interface being connected via a data bus to a first bus communication interface of a first mobile radio communication device; wherein the second mobile radio communication interface is designed to receive a network signal from the mobile radio communication network and to compare a signal strength of the received network signal with a threshold value, wherein the second mobile radio communication interface is further designed to provide the network identification and if the threshold value is exceeded by the received network signal read out the network address of the cellular network and the second cellular subscriber identifier from the second integrated subscriber identity module and send the second cellular subscriber identifier together with the network identification, the network address of the cellular network and the second data to the network address of the cellular network; and if the received network signal falls below the threshold value, to transmit the network address of the cellular network together with the network identification, the second data and the second cellular subscriber identifier to the second bus communication interface; wherein the second bus communication interface is designed to transmit the received network address of the cellular network together with the network identification, the second data and the second cellular subscriber identifier via the data bus to the first bus communication interface of the first cellular communication device.
Such a second mobile radio communication device ensures particularly secure and highly available communication due to the cooperative data transmission with the first mobile radio communication device. If the radio signal of the second communication device is difficult to receive, for example because the second communication device is in the shaded position, the data can be transmitted via the bus communication interface to the first mobile radio communication device and through this via its mobile radio communication interface to the mobile radio network. The second mobile radio communication system thus allows fail-safe mobile radio communication and guarantees a low and high failure rate due to the cooperative communication with the first mobile radio communication device when communicating from person-to-person, person-to-machine and / or machine-to-machine Availability. In particular, the second mobile radio communication device ensures fail-safe and highly available mobile radio communication via mobile radio networks and network technologies, in particular via network slices of the 5G system architecture, as described in this disclosure.
In an exemplary embodiment of the second mobile radio communication device, the second data memory is designed to delete the second data when the threshold value is exceeded after the second data has been sent to the network address of the mobile radio network; or to delete the second data if the threshold value is not reached after the second data has been sent to the first bus communication interface of the first mobile radio communication device.
This ensures particularly efficient recording of the data. As soon as the second data is forwarded, either to the cellular network with a good radio channel or to the first cellular communication device in the case of a poor radio channel of the second cellular communication device, the second memory can be erased to make room for the recording of further data. The second mobile radio communication device can thus record measurement data over a very long period of time or even record it continuously, since space is repeatedly created in the second memory for new, second data.
According to a third aspect, the invention relates to a method for cooperative communication of a first mobile radio communication device and a second mobile radio communication device via a mobile radio network, the mobile radio network having a network identification, the first mobile radio communication device having the following features: a first mobile radio communication interface for communication with the cellular network, the first cellular communication interface having a first integrated subscriber identity module (iSIM: Integrated Subscriber Identity), the first integrated subscriber identity module being implemented as an embedded integrated circuit and a first cellular subscriber identifier together with the Permanently stores network identification and a network address of the cellular network, the first cellular subscriber identifier identifying the first integrated subscriber identity module in the cellular network icated; a first data memory which is set up to store first data for transmission to the cellular network; a first bus communication interface; and wherein the second mobile radio communication device has the following features: a second mobile radio communication interface for communication with the mobile radio network, the second mobile radio communication interface having a second integrated subscriber identity module (iSIM: Integrated Subscriber Identity), the second integrated subscriber identity module as an embedded one Integrated circuit is implemented and permanently stores a second mobile radio subscriber identifier together with the network identification and the network address of the mobile radio network, the second mobile radio subscriber identifier being the second integrated subscriber ID
Identity module in the cellular network; a second data memory which is set up to store second data for transmission to the cellular network; a second bus communication interface, the second bus communication interface being connected to the first bus communication interface via a data bus; the method comprising the following steps: receiving a network signal from the cellular communication network via the second cellular communication interface; Comparing a signal strength of the received network signal with a threshold value; Reading out the second mobile radio subscriber identification, the network identification and the network address of the mobile radio network from the second integrated subscriber identity module; if the received network signal exceeds the threshold value: sending the second mobile radio subscriber identifier together with the network identification, the network address of the mobile radio network and the second data to the network address of the mobile radio network; and if the received network signal falls below the threshold value: transmission of the network identification and the network address of the cellular network together with the second data and the second cellular subscriber identifier to the second bus communication interface; Sending the received network identification and the network address of the cellular network together with the second data and the second cellular subscriber identifier by the second bus communication interface via the data bus to the first bus communication interface of the first cellular communication device; and sending the received second data together with the second mobile radio subscriber identifier and the network identification through the first mobile radio communication interface to the network address of the mobile radio network.
Due to the cooperative data transmission by the two mobile radio communication devices, such a method ensures particularly secure and highly available communication. If the radio signal from the second communication device is difficult to receive, for example because the second communication device is in the shadow, the data can be transmitted via the bus communication interface to the first mobile communication device and through this via its mobile communication interface to the mobile network. The same applies to the opposite direction and to the design with more than two mobile radio communication devices. In the case of several mobile radio communication devices, the data can be forwarded, for example, via the respective bus communication interfaces to the communication device which receives the best network signal, and can be transmitted through this to the mobile radio network. This allows a particularly high availability of the data transmission to the cellular network.
The method thus allows fail-safe cellular communication and guarantees a low failure rate and / or machine-to-machine communication between the cellular communication devices in human-to-human, human-to-machine and / or machine-to-machine communication high availability. In particular, the method ensures fail-safe and highly available cellular communication via cellular networks and network technologies, in particular via network slices of the 5G system architecture, as described in this disclosure.

In the following, network access entities, mobile radio communication devices and functions of such network access entities and mobile radio communication devices are described. The network access entity ensures access and mobility management in the cellular network. Mobile radio communication devices can use the network access entity to register with their mobile radio subscriber identification, for example UE ID or IMSI, in the mobile radio network and receive permission to set up a communication connection. For example, the network access entity in the 5G network can be an AMF (Access and Mobility Management Function) in order to provide access and mobility management functions. The AMF manages access and mobility control and may also include network slice selection functionality. In the 4G network, the network access entity can also be an MME (mobility management entity). This provides the functions of paging for setting up calls and generally communication connections as well as signaling for control purposes. The network access entity connects the core network to the access network and manages the whereabouts of all mobile radio communication devices in the radio cells connected to it.
The network access entity also establishes a security relationship with a mobile radio communication device in order to then be able to install security elements, for example keys, in the mobile radio communication device and in the network application function (NAF) of the network access function, for example via the network protocols Diameter and Hypertext Transfer Protocol (http).
1 shows a block diagram of a communication system 100 according to an exemplary embodiment with two mobile radio communication devices 131, 132 for cooperative communication via a mobile radio network 110. The mobile radio network 110 has a network identification 111 which uniquely identifies the mobile radio network 110.
The cellular network 110 is identified by its network identification (ID1) 111 and can be addressed via its network address 112. For example, there is a network access entity in the cellular network 110 which regulates the access to the cellular network 110. The mobile radio network 110 can then be addressed or reached via the network address of this network access entity. This network access entity knows the network identification 111 of the cellular network 110 and can manage access to the cellular network 110.
The network access entity for the cellular network 110 can for example be a RAN (Radio Access Network) entity, such as a base station or a radio access entity or an AMF (Access and Mobility Management Function) entity in the 5G network.
The first mobile radio communication device 131 has a first mobile radio communication interface 141 for communication with the mobile radio network 110. The first mobile radio communication interface 141 comprises a first integrated subscriber identity module (iSIM: Integrated Subscriber Identity) 151, which is implemented as an embedded integrated circuit and permanently stores a first mobile radio subscriber identifier 113 together with the network identification 111 and a network address 112 of the mobile radio network 110. The first mobile radio subscriber identifier 113 identifies the first integrated subscriber identity module 151 in the mobile radio network 110.
The first mobile radio communication device 131 also has a first data memory 181, which is set up to store first data 114 for transmission to the mobile radio network 110, and a first bus communication interface 171.
The second cellular communication device 132 has a second cellular communication interface 142 for communication with the cellular network 110. The second cellular communication interface 142 includes a second integrated subscriber identity module (iSIM: Integrated Subscriber Identity) 152, which as an embedded integrated Circuit is implemented, and a second mobile radio subscriber identifier 123 together with the network identification 111 and the network address 112 of the mobile radio network 110 permanently stored. The second mobile radio subscriber identifier 123 identifies the second integrated subscriber identity module 152 in the mobile radio network 110.
The second mobile radio communication device 132 has a second data memory 182 which is set up to store second data 124 for transmission to the mobile radio network 110.
The second mobile radio communication device 132 also has a second bus communication interface 172, which is connected to the first bus communication interface 171 via a data bus 173.
The fixed storage means that the first mobile radio subscriber identifier 113 together with the network identification 111 and the network address 112 of the mobile radio network 110 are stored in the first integrated subscriber identity module 151 even when the power supply is switched off. The same applies to the permanent storage of this data in the second integrated subscriber identity module 152.
The first cellular subscriber identifier 113 is, for example, an identifier of the first subscriber in the cellular network 110, for example an IMSI (International Mobile Subscriber Identity, that is, a number for the unique identification of network subscribers in the cellular network 110. The first cellular subscriber identifier 113 can include parameters for identifying and authenticating the first subscriber of the first mobile radio communication device 131 in the mobile radio network 110. The same applies to the second mobile radio subscriber identifier 123 and the second subscriber of the second mobile radio communication device 132.
The second cellular radio communication interface 142 is designed to receive a network signal 115 from the cellular radio communication network 110 and to compare a signal strength of the received network signal 115 with a threshold value 116. The mobile radio communication interface 142 is designed, the network identification 111, the network address 112 of the mobile radio network 110 and the second mobile radio subscriber identifier 123 are read from the second integrated subscriber identity module 152.
If the threshold value 116 is exceeded by the received network signal 115, the network identification 111, the network address 112 of the cellular network 110 and the second cellular subscriber identifier 123 are transmitted through the second cellular communication interface 142 together with the second data 124 to the network address 112 of the cellular network 110 .
When the received network signal 115 falls below the threshold value 116, the network address 112 of the cellular network 110 together with the network identification 111, the second data 124 and the second cellular subscriber identifier 123 through the second cellular communication interface 142 to the second bus communication interface 172 transmitted.
The second bus communication interface 172 is designed to send the received network address 112 of the cellular network 110 together with the network identification 111, the second data 124 and the second cellular subscriber identifier 123 via the data bus 173 to the first bus communication interface 171 of the first cellular communication device 131 .
The first mobile radio communication interface 141 is designed to send the received second data 124 together with the second mobile radio subscriber identifier 123 and the network identification 111 to the network address 112 of the mobile radio network 110.
Such a mobile radio communication system 100 ensures particularly secure and highly available communication due to the cooperative data transmission by the two mobile radio communication devices 131, 132. If the radio signal 115 of the second communication device 132 is difficult to receive, for example because the second communication device 132 is in the shaded position, the second data 124 can be transmitted via the second bus communication interface 172 to the first mobile radio communication device 131 and through this via its mobile radio communication interface 141 to the mobile radio network 110. The same applies to the opposite direction and to the design with more than two mobile radio communication devices 131, 132.
In the case of a plurality of mobile radio communication devices, the data can be forwarded, for example, via the respective bus communication interfaces to the communication device which receives the best network signal, and can be transmitted through this to the mobile radio network 110. This allows a particularly high availability of the data transmission to the mobile radio network 110. The mobile radio communication system 100 thus allows fail-safe mobile radio communication and, due to the cooperative communication among the mobile radio communication devices 131, 132, guarantees communication from person-to-person, person-to-person. Machine and / or ma
machine-to-machine a low failure rate and high availability. In particular, the mobile radio communication system 100 ensures fail-safe and highly available mobile radio communication via mobile radio networks and network technologies, in particular via network slices of the 5G system architecture, as also described in more detail in FIG.
The communication system 100 is shown here only by way of example. It can also include further cellular networks, which can be constructed similarly to the network 110 shown here. Furthermore, networks with other radio access technologies can also be implemented in addition to or instead of the mobile radio network 110, for example WLAN or WiFi networks. Other mobile radio communication devices than the two 131, 132 described here can also stay in the communication system 100 and communicate.
In addition to the first and second integrated subscriber identity modules 151, 152 shown in FIG. 1, the mobile radio communication devices 131, 132 can also each comprise further subscriber identity modules, for example iSIMs for access to other mobile radio networks, for example using other network access technologies.
The second data 124 can be assigned to the second subscriber identity module 152. For example, the second data 124 can be data that can no longer be stored in the second subscriber identity module 152 and are therefore swapped out to the data memory 182. This can be, for example, measured values which were measured by the second subscriber identity module 152, for example recorded images or voice data, or temperature values, pressure values, level values, currents, voltage values, etc. The same applies to the first data 114 of the first subscriber Identity module 151.
Both the first and the second mobile radio communication device 131, 132 can each comprise an actuator or an interface to an actuator, which are designed to provide a control command for controlling the actuator from the first or second data 114, 124 in the first or to derive or read out second data memory 181, 182 and to forward it to the actuator or the interface to the actuator in order to move the actuator accordingly.
The actuator can be, for example, a machine component that can be controlled by the first or second data 114, 124. The actuator can be, for example, a household appliance that can be controlled in the automated house or home via the first or second data 114, 124. Alternatively, the actuator can be, for example, a loudspeaker or a vibration device of the first or second mobile radio communication device 131, 132, which can be controlled and activated via the first or second data 114, 124.
The cellular network 110 can, for example, be a subnetwork or slice of a 5G cellular network, as described in more detail for FIG. 4, for example.
Both the first and the second mobile radio communication device 131, 132 can each include a sensor which is designed to detect a value of a physical variable and the value as the first or second data 114, 124 in the first or second data memory 181, 182 to save. The physical variable can be, for example, a temperature value, a pressure value, a level value, a current intensity, a voltage value, etc.
The data bus 173 can connect the second bus communication interface 172 to the first bus communication interface 171, bypassing the cellular network 110.
This achieves the advantage that the two mobile radio communication devices 131, 132 are directly connected via the two bus communication interfaces 171, 172 without communication having to be established via the mobile radio network 110 first. This ensures a high level of availability, since the communication path between the two communication devices 131, 132 has to bridge a shorter distance than the communication path in uplink and downlink via the cellular network 110. For example, the communication path between the two communication devices 131, 132 can be a side-link communication path be that realizes a direct cellular communication link between the two communication devices 131, 132, for example in accordance with the cellular radio standard 5G NR V2X (5G New Radio Vehicle-to-Anything).
Instead of a cellular connection, however, a WLAN connection or a Bluetooth connection can also be implemented as a bus communication interface 171, 172. Alternatively, the communication path between the two communication devices 131, 132 can also be, for example, wired, for example implemented as a USB connection or as a powerline connection. This can be useful if the communication devices 131, 132 are loT devices, e.g. loT sensors or loT actuators, which are not far from each other in the home network or in the factory and are to transmit different data, for example temperature, pressure, switch position, alignment of machine components, control signals, etc.
FIG. 1 also shows a second mobile radio communication device 132 for cooperative communication via a mobile radio network 110, the mobile radio network (110) having a network identification (111).
The second mobile radio communication device 132 comprises a second mobile radio communication interface 142 for communication with the mobile radio network 110, wherein the second mobile radio communication interface 142 has a second integrated subscriber identity module (ISIM: Integrated Subscriber Identity) 152, wherein the second integrated subscriber identity Identity module 152 is implemented as an embedded integrated circuit and a second
Mobile radio subscriber identifier 123 permanently stored together with the network identification 111 and the network address 112 of the mobile radio network 110, the second mobile radio subscriber identifier 123 identifying the second integrated subscriber identity module 152 in the mobile radio network 110.
The second mobile radio communication device 132 comprises a second data memory 182 which is set up to store second data 114 for transmission to the mobile radio network 110.
The second mobile radio communication device 132 comprises a second bus communication interface 172 which is connected to the first bus communication interface 171 of the first mobile radio communication device 171 via a data bus 173.
The second mobile radio communication interface 142 is designed to receive a network signal 115 from the mobile radio communication network 110 and to compare a signal strength of the received network signal 115 with a threshold value 116.
The second mobile radio communication interface 142 is also designed to read out the network identification 111 and the network address 112 of the mobile radio network 110 and the second mobile radio subscriber identifier 123 from the second integrated subscriber identity module 152 when the threshold value 116 is exceeded by the received network signal 115 to send the second mobile radio subscriber identifier 123 together with the network identification 111, the network address 112 of the mobile radio network 110 and the second data 124 to the network address 112 of the mobile radio network 110.
The second mobile radio communication interface 142 is also designed, if the received network signal 115 falls below the threshold value 116, the network address 112 of the mobile radio network 110 together with the network identification 111, the second data 124 and the second mobile radio subscriber identifier 123 to the second bus. Communication interface 172 to transmit.
The second bus communication interface 172 is designed to send the received network address 112 of the cellular network 110 together with the network identification 111, the second data 124 and the second cellular subscriber identifier 123 via the data bus 173 to the first bus communication interface 171 of the first cellular communication device 131 .
The second data memory 182 can be designed to delete the second data 124 when the threshold value 116 is exceeded after the second data 124 has been sent to the network address 112 of the cellular network 110; or to delete the second data 124 if the threshold value 116 is undershot after the second data 124 has been sent to the first bus communication interface 171 of the first mobile radio communication device 131.
This ensures particularly efficient recording of the data. As soon as the second data 124 is forwarded, either to the cellular network 110 with a good radio channel or to the first cellular communication device 131 in the case of a poor radio channel of the second cellular communication device 132, the second memory 182 can be erased in order to create space for the recording of further second data . The second mobile radio communication device 132 can thus record measurement data over a very long period of time or even record it continuously, since space is repeatedly created in the second memory 182 for new second data 124.
2 shows a block diagram of a communication system 200 for cooperative communication according to an exemplary embodiment, in which the two mobile radio communication devices 131, 132 transmit data at different time intervals 201, 202.
The communication system 200 can be constructed in accordance with the communication system 100 described in FIG. 1.
In the communication system 200, the second bus communication interface 172 of the second mobile radio communication device 132 is designed to receive a master signal from the first bus communication interface 171, and in response to the receipt of the master signal to instruct the second mobile radio communication interface 142 to transmit the Network identification 111 and the network address 112 of the cellular network 110 together with the second data 124 and the second cellular subscriber identifier 123 to the network address 112 of the cellular network 110 and the network identification 111 and the network address 112 of the cellular network 110 together with the second data 124 and the second The mobile radio subscriber identifier 123 only needs to be sent out via the data bus 173 to the first bus communication interface 171 of the first mobile radio communication device 131.
This achieves the advantage that one of the two mobile radio communication devices, here the first mobile radio communication device 131 using the example of FIG. 2, can be set up as a communication master via which the mobile radio communication with the network 110 is to take place.
This master communication device 131 can, for example, be equipped with particularly high resources for cellular communication or it can be set up where the radio channel to the cellular network 110 is particularly good, for example on the roof of the house, while the other cellular communication devices, such as For example, the second mobile radio communication device 132 in FIG. 2 can be set up at other locations with poor radio reception. Your data can then be sent to the master communication via the bus interface 172, 171
device 131, for example via the powerline of the house from the basement to the roof. The other mobile radio communication devices can then be set up in the basement, for example, where a lot of measurement data is available. Or the other mobile radio communication devices can be set up in a security area where security-relevant data can be recorded which can be transmitted to the master communication device 131 via the bus communication interface 172, 171.
The first mobile radio communication interface 141 can also be designed to additionally add the first mobile radio subscriber identifier 113 when sending the received second data 124 together with the second mobile radio subscriber identifier 123 and the network identification 111 to the network address 112 of the mobile radio network 110.
The cellular network 110 thus knows from the received data on the one hand which device these data originate from and on the other hand which device has transmitted the data. The cellular network 110 thus knows, when it has received data with both the first cellular subscriber identifier 113 and the second cellular subscriber identifier 123, that there are or have been problems with the radio accessibility of the second cellular communication device 132 via the second cellular communication interface 142. The network 110 can thus initiate suitable repair measures, for example changing the radio resources, for example by transmitting via a different radio channel, or inform a maintenance technician so that he can carry out a repair in the second mobile radio communication device 132.
The first mobile radio communication interface 141 can be designed to send the first data 114 together with the first mobile radio subscriber identifier 113 and the network identification 111 to the network address 112 of the mobile radio network 110 in the first time interval 201. The first mobile radio communication interface 141 can furthermore be designed to send the received second data 124 together with the second mobile radio subscriber identifier 123 and the network identification 111 to the network address 112 of the mobile radio network 110 in the second time interval 202. Here, the first time interval 201 can differ from the second time interval 202.
The two communication devices 131, 132 can thus transmit their data to the mobile radio network 110 at different time intervals. The radio interface of the mobile radio network 110 is thus used efficiently and there is no overload when two or more communication devices transmit their data, since this does not happen at the same time. Furthermore, the design of the communication system 200 can thus be better planned and the system can work in a resource-efficient manner.
The second bus communication interface 172 can be designed to send the network identification 111 and the received network address 112 of the cellular network 110 together with the second data 124 and the second cellular subscriber identifier 123 in the first time interval 201 via the data bus 173 to the first bus. To send out communication interface 171 of the first mobile radio communication device 131.
The two interfaces, cellular radio communication interface 141, 142 and bus communication interface 171, 172 can thus be used reciprocally and thus particularly efficiently. While the first mobile radio communication interface 141 of the first communication device 131 transmits the first data 114 of the first mobile radio communication device 131 to the mobile radio network 110 in the first time interval 201, the second data 124 of the second mobile radio communication device 132 are simultaneously, that is, in the first time interval 201 transmitted via the bus communication interface 172, 171 to the first mobile radio communication device 131. This means that both interfaces are used particularly efficiently.
3 shows a block diagram of a communication system 300 for cooperative communication according to an exemplary embodiment, in which the second mobile radio communication device 132 can be registered with the mobile radio network 110 via the first mobile radio communication device 131.
The communication system 300 can be constructed in accordance with the communication system 100 described in FIG. 1 and also in accordance with the communication system 200 described in FIG.
The second cellular communication interface 142 is designed to send a registration request 310 for registering the second cellular communication device 132 in the cellular network 110 to the network address 112 of the cellular network 110 when the received network signal 115 exceeds the threshold value 116.
The second cellular communication interface 142 is also designed, when the received network signal 115 falls below the threshold value 116, the registration request 310 for registering the second cellular communication device 132 in the cellular network 110 via the second bus communication interface 172, the first bus communication interface 171 and the first mobile radio communication interface 141 to be sent to the network address 112 of the mobile radio network 110.
The first mobile radio communication interface 141 is designed to send a confirmation 311 of the mobile radio network 110 to the registration request 310 for registering the second mobile radio communication device 132 in the mobile radio network 110 via the first bus communication interface 171 to the second bus communication interface 172 of the second mobile radio Communication device 132 to transmit.
With a good connection to the network 110, the second mobile radio communication device 132 can thus automatically register via its mobile radio communication interface 142 in the network 110, while it can register itself in the network 110 via the first mobile radio communication device 131 in the case of a poor network connection. The confirmation B 311 of the registration request R 310 is forwarded from the first mobile radio communication device 131 to the second mobile radio communication device 132 via the bus communication interface 171, 172.
The registration request R 310 can include, for example, the second mobile radio subscriber identifier 123 of the second integrated subscriber identity module 152. The registration request 310 can be transmitted to a network access entity of the cellular network 110 by means of the first mobile radio communication device 131.
This network access entity can then query subscriber-specific registration data of the second integrated subscriber identity module 152 from a database of the mobile radio network 110 or from an external database based on the second mobile radio subscriber identifier 123 of the second integrated subscriber identity module 152.
Then the network access data for the access of the second integrated subscriber identity module 152 to the cellular network 110 through the network access entity to the second integrated subscriber identity module 152 via the first cellular communication interface 141 and the bus communication interfaces 171, 172 to the second Mobile radio communication device 132 are transmitted. The network access data for the access of the second integrated subscriber identity module 152 to the cellular network 110 are based, for example, on the subscriber-specific registration data of the second integrated subscriber identity module 152, such as the second cellular subscriber identifier 123 of the second integrated subscriber identity module 152 or other registration data of the second integrated subscriber identity module 152, for example a name, a password, a network key, etc.
The network access data indicate capabilities of the mobile radio network 110, in particular those capabilities which can be used for the second integrated subscriber identity module 152. Finally, the communication connection is established by the second integrated subscriber identity module 152 and the corresponding network elements of the cellular network 110 based on the network identification 111, the second cellular subscriber identifier 123 of the second subscriber identity module 152 and the network access data to the cellular network 110.
The network access data can, for example, indicate the following capabilities of the cellular network 110: number and type of network slices that can be allocated by the cellular network 110 or to which the cellular network 110 can establish a communication connection, support of specific network slice functions, the ability to transfer data and / or to transmit voice, support of 2G / 3G, 4G and / or 5G roaming, support of a specific service by the cellular network 110.
The registration request can furthermore have an identification of a specific service for which the second integrated subscriber identity module 152 requests the mobile radio network 110. The specific service can be provided by the cellular network 110 based on the identification of the specific service if the cellular network 110 supports the specific service. Otherwise, that is, if it does not support the specific service, the network access entity can transmit a network identification of another cellular network to the second integrated subscriber identity module 152 which supports the specific service.
The registration request R 310 can further comprise a key for authenticating the second integrated subscriber identity module 152. The network access entity can authenticate the second integrated subscriber identity module 152 via an authentication entity of the cellular network 110 based on the key. This can be done before the participant-specific registration data is queried.
4 shows a schematic illustration of a first and a second mobile radio communication device 131, 132 for cooperative communication according to the disclosure in a 5G communication system 400 according to an exemplary embodiment according to the specification 3GPP TS 23.501. The various blocks which such a 5G communication system 400 comprises are shown schematically in FIG.
The first mobile radio communication device 131 and the second mobile radio communication device 132 each correspond to the user equipment (UE) or client terminal, which can be operated by the subscriber in order to initiate communication in the 5G network, i.e. communication to start (mobile originating, MO) or accept (mobile terminating, MT). The first mobile radio communication device 131 and also the second mobile radio communication device 132 can initiate a communication without user interaction, for example the mobile radio communication devices 131, 132 can be a machine terminal, for example for a car, a machine, a robot or a other device.
The (R) AN ((Radio) Access Network) entity 331 represents the (radio) access network with which the first and the second mobile radio communication device 131, 132 receive access to the 5G communication network. The interface between the respective mobile radio communication device 131, 132 and (R) AN can be an air interface if the access network 331 is a radio network or can be wired if the access network 331 is a wired network.
The AMF (Access and Mobility Management Function) entity 340 represents the access and mobility management function. This is used to manage the access and mobility control. The AMF 340 may also include network slice selection functionality. With wireless access, mobility management is usually not required.
The SMF (Session Management Function) entity 341 represents the session management function. The SMF entity 341 sets up sessions and manages them in accordance with the network policy or network planning.
The UFF (User Plane Function) entity 332 represents the User Plane Function. Such User Plane Functions can be applied in various configurations and locations, according to the type of service.
The POF (Policy Control Function) entity 342 represents the policy (or planning) control function. The PCF entity 342 thus provides a policy framework which includes network slicing, roaming and mobility management. This corresponds to the functionality of a PCRF in 4G systems.
The UDM (Unified Data Management) entity 352 provides a common data management. With this data management, participant data and profiles are saved. This corresponds to the functionality of an HSS in 4G systems, but can be used for both mobile and wired access in the NG Core network.
The first communication interface 141 can, for example, transmit the first data 114 together with the network parameters 111, 112, 113, as described above for FIGS. 1 to 3, to the UDM 352 block. For example, measured values or measurement parameters that were recorded by the first mobile radio communication device 131 can be stored in the network 400. The same applies to the transmission of the second data 124 by the second mobile radio communication device 132.
The DN (Data Network) 333 provides the data network via which data is transmitted, for example from the first mobile radio communication device 131 to the second mobile radio communication device 132 or to another mobile radio communication device or UE. For example, two machine terminals 131, 132, as described above for FIGS. 1 to 3, can communicate with one another via the data network 333.
The first data 114 can thus be transmitted from the first mobile radio communication device 131 to the second mobile radio communication device 132 or to another mobile radio communication device or other UE via the DN 333.
The AUSF (Authentication Server Function) entity 351 provides authentication functionality with which the subscriber or the first and the second mobile radio communication device 131, 132 can register in the network. The first integrated subscriber identity module 151 and the second integrated subscriber identity module 152 can authenticate themselves in the 5G network 400, for example, via the AUSF block 351.
The AF (Application Function) entity 351 provides application functions with which certain services can be carried out, for example services that are set up or used by the first integrated subscriber identity module 151 or the second integrated subscriber identity module 152.
The NSSF (Network Slice Selection Function) entity 350 provides functions to select certain network slices. For example, the first integrated subscriber identity module 151 or the second integrated subscriber identity module 152 can select a first slice or a second slice in the 5G communication system 400 and communicate via it or transmit their data 114, 124 there.
The 5G communication system 400 shown in Figure 4 corresponds to the 5G system architecture according to the specification 3GPP TS 23.501 and represents the structure of the NG (Next Generation) network, which consists of network functions (NFs) and reference points that connect the NFs. In the specification 3GPP TS 23.501, however, the terminal is only generally referred to as UE (User Equipment) without the special embodiment shown here in FIGS. 1 to 3 with integrated subscriber identity modules iSIMI or iSIM2. The first and second mobile radio communication devices 131, 132 or UE are connected either to a radio access network (RAN) 331 or to an access network (AN) 331. In addition, the first and second mobile radio communication devices 131, 132 or UE are connected to the access and mobility function (AMF) 340. The RAN331 is a base station that uses new RAT (Radio Access Technology) and advanced LTE technologies, while the AN 331 is a general base station with non-3GPP access, such as WiFi. The next generation core network or the 5G communication system 400 shown in FIG. 4 consists of various network functions (NFs). In Figure 4 there are seven Next Generation Core NFs, namely (1) AMF 340, (2) Session Management Function (SMF) 341, (3) Policy Control Function (PCF) 342, (4) Application Function (AF) 343, (5) Authentication Server Function ( EX) 351, (6) User Level Function (UPF) 332, and (7) User Data Management (UDM) 352. The integrated subscriber identity modules 151, 152 can select one or more network functions from them to initiate the communication.
The network function (NF) represents the processing function taken over by 3GPP in NextGen or NG. It has both functional behavior and at the same time serves as an interface. An NF can either be implemented on dedicated hardware as a network element or run as a software instance on dedicated hardware
or as a virtualized function instantiated on a suitable platform, e.g. B. be implemented in a cloud infrastructure.
The AMF 340 or AMF entity 340 offers UE-based authentication, authorization, mobility management, etc. A mobile radio communication device 130 is connected to a single AMF 340, for example, since the AMF 340 is independent of the access technology. This means that a first or second mobile radio communication device 131, 132 with multiple access technologies also only needs to be connected to a single AMF 340.
This AMF 340 forms, for example, a network entity with network identification 111 and network address 112, as described above for FIGS. 1 to 3, and is responsible for terminating the messages or communication requests of the first or second integrated subscriber identity module 151, 152 or to answer in order to initiate a communication of the first or second integrated subscriber identity module 151, 152 in the cellular network 110.
The AMF 340 can also process the messages or communication requests of the first or second integrated subscriber identity module 151, 152 and forward them to a second cellular network, for example a second network slice of the communication system 400, for example to enable communication of the first or second integrated To initiate subscriber identity module 151, 152 in a second network slice.
The SMF 341 or SMF entity 341 is responsible for session management and assigns one or more IP addresses to the corresponding mobile radio communication device 131, 132. In addition, the SMF 341 selects the UPF 332 and controls the UPF 332 with regard to the data transfer, for example for the transfer of the data 114, 124. If a mobile radio communication device 131, 132 has several sessions, different SMFs 341 can be assigned to each session in order to handle them to be controlled individually and possibly to provide several functionalities per session.
The AF 343 or AF entity 343 provides information about the packet flow and provides it to the PDF 342, which is responsible for policy control, in order to ensure the Quality of Service (QoS). Based on this information, POF 342 determines the mobility and session management policies for the AMF 340 and SMF 341 to function properly.
The AUSF 351 or AUSF entity 351 stores data for the authentication of the respective mobile radio communication device 131, 132, while the UDM 352 stores subscription data or subscriber data of the corresponding mobile radio communication device 131, 132. The data network DN 333, which is not part of the NG Core network 400, provides Internet access and operator services.
The reference point representation of the architecture can be used to represent detailed message flows in the next generation (NG) standardization. The reference point N1 301 is defined as transmission signaling between the first or second mobile radio communication device 131, 132 and the AMF 340. The reference points for the connection between the AN 331 and the AMF 340 and between the AN 331 and the UPF 332 are N2 302 and N3, respectively 303 defined. There is no reference point between the AN 331 and the SMF 341, but there is a reference point, N11 311, between the AMF 340 and the SMF 341. This means that the SMF 341 is controlled by the AMF 340. N4 304 is used by the SMF 341 and the UPF 332 so that the UPF 332 can be set with the generated control signal from the SMF 341, and the UPF 332 can report its status to the SMF 341. N9 309 is the reference point for the connection between different UPFs 332 and N14 314 is the reference point between different AMFs 340. N15 315 and N7 307 are defined so that the PCF 342 can apply its guidelines to the AMF 340 or the SMF 341. N12 312 is required so that the AMF 340 can carry out the authentication of the respective mobile radio communication device 131, 132. N8, 308 and N10, 310 are defined because the subscription data of the respective mobile radio communication device 131, 132 are required by the AMF 340 and the SMF 341.
The next generation network 400 aims at realizing a separation of the user and control level. The user plane carries the user traffic while the control plane carries the signaling in the network. In Figure 4, the UPF 332 is in the user level and all other network functions, that is, AMF 340, SMF 341, PCF 342, AF 343, AUSF 351 and UDM 352 are in the control level. The separation of the user and control level guarantees the independent scaling of the resources of each network level. The separation also allows UPFs 332 to be provided in a distributed manner separate from the functions of the control plane.
The NG architecture 400 consists of modularized functions. For example, the AMF 340 and the SMF 341 are independent functions in the control plane. Separate AMF 340 and SMF 341 allow independent development and scaling. Other control level functions such as the PCF 342 and the AUSF 351 can also be separated. The modularized functional design shown in FIG. 4 also enables the next generation network 400 to flexibly support a wide variety of services.
Each network function interacts directly with a different NF. In the control plane, a number of interactions between two NFs are defined as a service so that they can be reused. This service enables the support of modularity. The user plane supports interactions such as forwarding operations between different UPFs 332.
The next generation network 400 supports roaming, that is, the ability of a cellular network subscriber to automatically receive or make calls in a cellular network other than his home network, to send and receive data or to have access to other cellular network services. There are two types of application scenarios, on the one hand Home Routed (HR), on the other hand local breakout (LBO). The first or second communication device 131, 132 can also use its data 114, 124 using the functionalities described above send via visited cellular network to its home network.
