    description
    The present invention relates to a mobile radio communication device with an integrated subscriber identity module (iSIM) and counter for data-limited communication via a mobile radio network and a corresponding method for this.
    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, cheap and resource-saving data transmission is increasingly becoming a basic requirement. With loT communication, a large amount of data assigned to the various sensors and actuators has to be transmitted to the network and vice versa. However, the costs of such a data transfer should not exceed the budget provided. There is therefore a need for cost-transparent data transmission of the measurement data to the network in order to be able to evaluate this data from many loT devices there and to generate appropriate control commands based on this data.
    It is the object of the present invention to create a concept for a cost and resource transparent data transmission, which in the communication of human-to-human, human-to-machine and / or machine-to-machine communication with ensures high cost and resource transparency.
    In particular, it is the object of the present invention to provide a mobile radio communication device that enables cost and resource-transparent data transmission in the network and in the opposite direction in accordance with prepaid data transmission, in particular using network slices of a 5G system architecture.
    With costs is meant here an effort or a complexity of resources that have to be made available for the transmission. Cost transparency means that the user has an overview of the resources to be provided.
    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 below 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, which means Internet of Things) and ultra-reliable low-latency communication (UR-LLC).
    The mobile radio communication devices described below comprise a mobile radio communication interface or simply referred to as a communication interface, which performs a variety of tasks. Such a communication interface can include, for example, a processor that is responsible for the described execution of the tasks. 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 cellular communication device for data-limited communication via a cellular network, the cellular network having a network identification, with the following features: a cellular communication interface for communication with the cellular network, the communication interface being an integrated subscriber identity module , iSIM: Integrated Subscriber Identity, wherein the integrated subscriber identity module is implemented as an embedded integrated circuit and permanently stores a cellular subscriber identifier together with the network identification and a network address of the cellular network, the cellular subscriber identifier being the integrated subscriber identity module in the cellular network identified; a data store; a sensor which is designed to detect a data value of a physical variable at predetermined times and to store it in the data memory; wherein the mobile radio communication interface is designed to read the data value recorded at a predetermined point in time from the data memory, to read out the mobile radio subscriber identifier, the network identification and the network address of the mobile radio network from the integrated subscriber identity module and to read the mobile radio subscriber identifier together with the network identification, the network address to send the cellular network and the current data value read out to the network address of the cellular network; a counter which is designed to reduce a counter reading of the counter starting from an initial counter reading by one counter decrement each time the data value is transmitted through the communication interface; a voltage supply which is designed to supply the integrated subscriber identity module with electrical voltage; and a controller which is designed to permanently disconnect the integrated subscriber identity module from the voltage supply when a counter threshold value is reached by the counter reading, in order to deactivate the integrated subscriber identity module.
    Such a mobile radio communication device ensures, due to the deactivation of the integrated subscriber identity module when the counter threshold value is reached, data transmission that is transparent in terms of costs and resources, which is important when communicating from person-to-person, person-to-machine and / or machine-to -Machine ensures communication with high cost and resource transparency. When a certain number of data transfers has been reached, the iSIM is deactivated so that no further costs are incurred. This enables prepaid data transmission to be implemented in the network and in the opposite direction. The communication device is particularly suitable when using network slices of a 5G system architecture, as described in more detail below.
    In an exemplary embodiment of the mobile radio communication device, the integrated subscriber identity module has a voltage supply connection which. is connected to the voltage supply via a thermally destructible fuse, the controller being designed to charge the thermally destructible fuse with an electric current and thereby thermally destroy the thermally destructible fuse in order to permanently deactivate the integrated subscriber identity module.
    These security measures ensure that when the counter threshold value is reached, the subscriber identity module can no longer be used, so that no further costs arise. The user can thus use the communication device until an existing credit associated with the counter threshold value has been used up. This means that the user has the full cost transparency of his installed loT communication devices at a glance at all times, without any unforeseen costs.
    In an exemplary embodiment of the mobile radio communication device, the controller is designed to charge the thermally destructible fuse in response to the counter threshold being reached with the electric current and thereby permanently deactivate the mobile radio communication interface with the integrated subscriber identity module.
    This has the technical advantage that the mobile radio communication device deactivates itself when the counter threshold value is reached by thermally destroying the thermal fuse with an electric current. From this point on, there are no further costs, so that the user can have full cost transparency. If the user nevertheless wishes to continue using the communication device, he can reset the counter reading to its initial value and replace the thermal fuse or replace the communication device as a whole.
    In an exemplary embodiment of the mobile radio communication device, the initial count of the counter is permanently stored in the counter.
    This achieves the technical advantage that the initial counter reading is predefined and can, for example, be assigned to a credit or a data volume which indicates how many transmissions of data can be carried out with the communication device. The user thus knows how many data transfers he can make with the communication device before the iSIM is deactivated.
    In an exemplary embodiment of the mobile radio communication device, the mobile radio communication interface is designed to delete the data value sent in each case from the memory.
    This offers the technical advantage that the recording time for the sensor data increases when the data values sent out are deleted from the memory after each transmission, so that no unnecessary data that has already been transmitted is stored in the data memory become.
    In an exemplary embodiment of the mobile radio communication device, the controller is designed to control the communication interface for sending out the respectively recorded data value between two consecutive predetermined times, and wherein the mobile radio communication interface is designed in response to the activation by the controller, the respectively recorded data value to send out.
    This has the technical advantage that the communication device works particularly efficiently when it reciprocally records data, i.e. at the predetermined times, and then sends the data to the network when no recording is taking place, i.e. between two consecutive predetermined times . The performance of the communication interface can thus be optimally used, since the activities to be processed are distributed over time.
    In an exemplary embodiment of the mobile radio communication device, the sensor is a temperature sensor, and the physical variable is a temperature.
    This has the technical advantage that temperature values can be efficiently transmitted to the network.
    In an exemplary embodiment of the mobile radio communication device, the mobile radio subscriber identifier is an IMSI (International Mobile Subscriber Identity).
    This achieves the technical advantage that the data transmitted in the network can be assigned to the corresponding mobile radio communication device using the IMSI, so that it is known at all times where the recorded data originate from. The IMSI (International Mobile Subscriber Identity) is a unique mobile subscriber identifier that is not assigned more than once and thus allows the data to be clearly identified.
    In an exemplary embodiment of the cellular communication device, the cellular network is a subnetwork of a 5G cellular network, the cellular communication device is a loT communication device, the cellular subscriber identifier being stored cryptographically encrypted in the integrated subscriber identity module using a public cryptographic key is, wherein the public cryptographic key is assigned to the mobile radio network, and wherein the mobile radio communication interface is designed to send out the cryptographically encrypted mobile radio subscriber identification.
    This offers the technical advantage that the mobile communication device with the iSIM can be used in 5G communication networks, in particular network slices, and because of the counter ensures transparency of the costs or the number of data transmissions or the number of data transmissions that are still possible at all times. 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 meter-based transmission of data, the user always has full cost and resource transparency.
    According to a second aspect, the invention relates to a method for data-limited communication of a mobile radio communication device via a mobile radio network, wherein the mobile radio network has a network identification, and wherein the mobile radio communication device has a mobile radio communication interface for communication with the mobile radio network, wherein the mobile radio communication Communication interface has an integrated subscriber identity module, iSIM: Integrated Subscriber Identity, wherein the integrated subscriber identity module is implemented as an embedded integrated circuit and permanently stores a cellular subscriber identifier together with the network identification and a network address of the cellular network, the cellular subscriber identifier identifying the integrated subscriber identity module in the cellular network; wherein the mobile radio communication device further comprises a data memory, a sensor, a counter and a voltage supply which is designed to supply the integrated subscriber identity module with electrical voltage; the method comprising the following steps: the sensor acquiring a data value of a physical quantity at predetermined times and storing the data value in the data memory; Reading out the data value acquired at a predetermined point in time from the data memory and reading out the mobile radio subscriber identification, the network identification and the network address of the mobile radio network from the integrated subscriber identity module; and sending out the mobile radio subscribers
    Identification together with the network identification, the network address of the cellular network and the current data value read out to the network address of the cellular network through the cellular communication interface; reducing a counter reading from an initial counter reading by one counter decrement by the counter each time the data value is transmitted by the communication interface ; Permanent disconnection of the integrated subscriber identity module from the voltage supply when a counter threshold value is reached by the counter reading in order to deactivate the integrated subscriber identity module.
    Due to the deactivation of the integrated subscriber identity module when the counter threshold value is reached, such a method ensures data transmission that is transparent in terms of costs and resources and which is used when communicating from person-to-person, person-to-machine and / or machine-to-machine Ensures communication with high cost and resource transparency. When a certain number of data transfers has been reached, the iSIM is deactivated so that no further costs are incurred. This enables prepaid data transmission to be implemented in the network and in the opposite direction. The method is particularly suitable when using network slices of a 5G system architecture, as described in more detail below.

    1 shows a schematic illustration of a mobile radio communication system 100 according to an exemplary embodiment with a mobile radio communication device 130 with an integrated subscriber identity module 150 and a counter 170 for data-limited communication according to the disclosure.
    The mobile radio communication device 130 is used for data-limited communication via a mobile radio network 110 with a network identification 111.
    The mobile radio communication device 130 has a mobile radio communication interface 140 for communication with the mobile radio network 110. The communication interface 140 has an integrated subscriber identity module (iSIM: Integrated Subscriber Identity) 150, which is implemented as an embedded integrated circuit, and permanently stores a mobile radio subscriber identifier 113 together with the network identification 111 and a network address 112 of the mobile radio network 110. The mobile radio subscriber identification 113 thereby identifies the integrated subscriber identity module 150 in the mobile radio network 110.
    The mobile radio communication device 130 furthermore has a data memory 180 and a sensor 160 which is designed to detect a data value 162 of a physical variable 161 at predetermined times and to store it in the data memory 180.
    The mobile radio communication interface 140 is designed to read the data value 114 recorded at a predetermined point in time from the data memory 180, to read out the first mobile radio subscriber identifier 113, the first network identification 111 and the network address 112 of the mobile radio network 110 from the integrated subscriber identity module 150 and to send the mobile radio subscriber identifier 113 together with the network identification 111, the network address 112 of the mobile radio network 110 and the current data value 114 read out to the network address 112 of the mobile radio network 110.
    The mobile radio communication device 130 has a counter 170 which is designed to reduce a counter reading of the counter 170 starting from an initial counter reading each time the data value 114 is transmitted by the communication interface 140 by a counter decrement.
    The mobile radio communication device 130 has a voltage supply 190 which is designed to supply the integrated subscriber identity module 150 with electrical voltage.
    The mobile radio communication device 130 has a controller 120 which is designed to permanently separate the integrated subscriber identity module 150 from the voltage supply 190 when the counter reading reaches a counter threshold value in order to deactivate the integrated subscriber identity module 150.
    Due to the deactivation of the integrated subscriber identity module 150 when the counter threshold value is reached, the mobile radio communication device 130 ensures a cost- and resource-transparent data transmission, which can be used in communication between person-to-person, person-to-machine and / or machine. to machine ensures communication with high cost and resource transparency.
    When a certain number of data transmissions has been reached, the iSIM 150 is deactivated by the controller 120, so that no further costs or expenses arise. Prepaid data transmission into network 110 and in the opposite direction can thus be implemented. The communication device 130 is particularly suitable when using network slices of a 5G system architecture, as described in more detail with regard to FIG. 3.
    The cellular network 110 is identified by its network identification (IDI) 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
    The 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 be, for example, 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, as shown below in relation to FIG. 3 described in more detail.
    The communication system 100 is shown here only as an 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. Further mobile radio communication devices 130 can also reside in the communication system 100 and communicate.
    In addition to the integrated subscriber identity module 150 shown in FIG. 1, the mobile radio communication device 130 can also comprise other such subscriber identity modules, for example it can be modules for access to other mobile radio networks, for example using other network access technologies.
    The fixed storage means that the 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 integrated subscriber identity module 150 even when the power supply is switched off.
    The mobile radio subscriber identifier 113 is, for example, an identifier of the subscriber in the mobile radio network 110, for example an IMSI (International Mobile Subscriber Identity, that is, a number for the unique identification of network subscribers in the mobile radio network 110. The mobile radio subscriber identifier 113 can include parameters to identify and authenticate the subscriber in the cellular network 110.
    The data 114 can be assigned to the subscriber identity module 150. For example, the data 114 can be data that can no longer be stored in the subscriber identity module 150 and are therefore swapped out to the data memory 180. This can be, for example, measured values that were measured by the subscriber identity module 150, for example recorded images or voice data, or temperature values, pressure values, level values, currents, voltage values, etc. By storing the data 114 in the data memory 180, these are not affected in the event of a fault in the subscriber identity module 150.
    The mobile radio communication device 130 can furthermore comprise an actuator or an interface to an actuator, which is designed to derive a control command for controlling the actuator from the data 114 in the data memory 180 or to read it and to the actuator or the Forward interface to the actuator to move the actuator accordingly.
    The actuator can be, for example, a machine component that can be controlled by the data 114. The actuator can be, for example, a household appliance that can be controlled in the automated house or home via the data 114. Alternatively, the actuator can be, for example, a loudspeaker or a vibration device of the mobile radio communication device 130, which can be controlled and activated via the data 114.
    The cellular network 110 can be, for example, a subnetwork or slice of a 5G cellular network, as described in more detail for FIG. 3, for example.
    2 shows a schematic illustration of a mobile radio communication system 200 according to an exemplary embodiment with a mobile radio communication device 130 with an integrated subscriber identity module 150, a counter 170 and a thermally destructible fuse 192 for data-limited communication according to the disclosure. The communication device 130 corresponds to the communication device 130 described above in relation to FIG. 1, a thermally destructible fuse 192 being additionally implemented on a voltage supply connection 191 of the ISIM 150.
    The integrated subscriber identity module 150 has a voltage supply connection 191 which is connected to the voltage supply 190 via a thermally destructible fuse 192. The controller 120 is designed to supply the thermally destructible fuse 192 with an electrical current 121 and thereby thermally destroy the thermally destructible fuse 192 in order to permanently deactivate the integrated subscriber identity module 150. The thermally destructible fuse 192 can be implemented as a fuse, for example.
    The controller 120 can supply the thermally destructible fuse 192 with the electric current 121 in response to the counter threshold being reached and thereby permanently deactivate the mobile radio communication interface 140 with the integrated subscriber identity module 150.
    The mobile radio communication device can thus deactivate itself when the counter threshold value is reached by thermally destroying the thermal fuse 192 with an electric current 121. From this point on, there are no further costs, so that the user can have full cost transparency at any time. If the user nevertheless wishes to continue using the communication device 130, he can restore the counter reading to his own
    Reset the initial value and replace the fuse 192 or he can replace the entire communication device 130.
    The initial count of the counter 170 can be permanently stored in the counter 170, for example.
    The initial counter reading can thus be predefined and, for example, allocated to a credit or data volume, which indicates how many transmissions of data 114 can be carried out with the communication device 130. The user thus knows how many transmissions of data 114 he can make with the communication device 130 before the iSIM 150 is deactivated.
    The mobile radio communication interface 140 can delete the respective transmitted data value 114 from the memory 180.
    This can increase the recording duration for the sensor data, since the data values sent in each case are deleted from the memory 180 after each transmission, so that no unnecessary data that have already been transmitted are stored in the data memory 180.
    The controller 120 can be designed to control the mobile radio communication interface 140 in order to transmit the data value 114 recorded in each case between two successive predetermined times. The mobile radio communication interface 140 can transmit the respective recorded data value 114 in response to the activation by the controller 120.
    The communication device 130 can thus work particularly efficiently when it reciprocally records data, that is to say at the predetermined times, and then sends the data to the network 110 when there is currently no recording, that is, between two consecutive predetermined times.
    The sensor 160 can be, for example, a temperature sensor, and the physical variable 161 can be a temperature.
    The mobile radio subscriber identifier 113 is, for example, an IMSI, that is to say a number for the unique identification of network subscribers in the mobile radio network 110. The mobile radio subscriber identifier 113 can include parameters for identifying and authenticating the subscriber in the mobile radio network 110.
    The cellular network 110 can be a subnetwork of a 5G cellular network, as described in more detail below with regard to FIG. 3. The mobile radio communication device 130 can be a loT communication device. The mobile radio subscriber identification 113 can be stored cryptographically encrypted in the integrated subscriber identity module 150 using a public cryptographic key. The public cryptographic key can be assigned to the cellular network 110. The mobile radio communication interface 140 can be designed to transmit the cryptographically encrypted mobile radio subscriber identification 113.
    The mobile radio communication device 130 with the iSIM 150 can thus be used in 5G communication networks, in particular network slices, as shown for example below in relation to FIG still possible number of data transfers.
    The advantages of the 5G system architecture 300, as described in more detail in relation to FIG. 3, 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 that Support of logical network functions, the application-specific assignment of functions such as speed, capacity, connectivity and network coverage in order to meet the special requirements of each application, the shared use of functional components across different network slices, etc. Due to the meter-based transmission of data 114 the user has full cost and resource transparency at all times.
    3 shows a schematic illustration of a mobile radio communication device 130 with iSIM 150 and counter 170 for data-limited communication according to the disclosure in a 5G communication system 300 according to an exemplary embodiment according to specification 3GPP TS 23.501. The various blocks which such a 5G communication system 300 comprises are shown schematically in FIG.
    The mobile radio communication device 130 corresponds to the user equipment (UE) or client terminal, which can be operated by the subscriber to initiate communication in the 5G network, i.e. to start communication (mobile originating, MO) or to accept it (mobile terminating, MT). The mobile radio communication device 130 can also initiate a communication without user interaction, for example it can be a machine terminal, for example for a car, a machine, a robot or some other device.
    The (R) AN ((Radio) Access Network) entity 331 represents the (radio) access network with which the mobile radio communication device 130 receives access to the 5G communication network. The interface between mobile radio communication device 130 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 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 communication interface 140 can, for example, transmit the data 114 together with the network parameters 111, 112, 113, as described above for FIGS. 1 to 2, to the block UDM 352. For example, measured values or measurement parameters that were recorded by the mobile radio communication device 130 can be stored in the network 300.
    The DN (Data Network) 333 provides the data network via which data is transmitted, for example from a cellular communication device 130 to another cellular communication device 130 or UE. For example, two machine terminals 130, as described above for FIGS. 1 to 2, can communicate with one another via the data network 333.
    The data 114 can thus be transmitted from the mobile radio communication device 130 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 mobile radio communication device 130 can register in the network. The integrated subscriber identity module 150 can, for example, authenticate itself in the 5G network 300 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 integrated subscriber identity module 150.
    The NSSF (Network Slice Selection Function) entity 350 provides functions to select certain network slices. For example, the integrated subscriber identity module 150 can select a first slice or a second slice in the 5G communication system 300 and communicate via it or transfer its data 114 to it.
    The 5G communication system 300 shown in Figure 3 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 Figure 3 with an integrated subscriber identity module iSIM 150 and counter 170. The mobile radio communication device 130 or UE is either connected to a radio access network ( Radio Access Network, RAN) 331 or an access network (AN) 331. In addition, the mobile radio communication device 130 or UE is connected to the access and mobility function (AMF) 340. The RAN 331 is a base station that uses the 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 300 shown in FIG. 4 consists of various network functions (NFs). In Figure 3 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 ( AUSF) 351, (6) User Level Function (UPF) 332 and (7) User Data Management (UDM) 352. The integrated subscriber identity modules 150, 160 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. A 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. That is to say, even a mobile radio communication device 130 with multiple access technologies 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 2, and is responsible for the messages or communication requests
    of the integrated subscriber identity module 150 of the mobile radio communication interface 140 or to respond to in order to initiate a communication of the integrated subscriber identity module 150 in the mobile radio network 110.
    The AMF 340 can also process the messages or communication requests of the integrated subscriber identity module 150 of the cellular communication interface 140 and forward them to a second cellular network, for example a second network slice of the communication system 300, for example to enable communication by the integrated subscriber -Identity module 150 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 mobile radio communication device 130. In addition, the SMF 341 selects the UPF 332 and controls the UPF332 with regard to the data transfer, for example for the transfer of the data 114. If a mobile radio communication device 130 has several sessions, different SMFs 341 can be assigned to each session in order to control them 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, so as 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 mobile radio communication device 130, while the UDM 352 stores subscription data or subscriber data of the mobile radio communication device 130. The data network DN 333, which is not part of the NG Core network 300, 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 mobile radio communication device 130 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 defined as N2 302 and N3 303, respectively . 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 authenticate the cellular radio communication device 130. N8, 308 and N10, 310 are defined because the subscription data of the mobile radio communication device 130 is required by the AMF 340 and the SMF 341.
    The next generation network 300 aims to achieve 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 3, 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 300 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 300 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 300 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). Communication device 130 can also transfer its data 114 to its home network using the functionalities described above via a visited cellular network send.
    4 shows a schematic illustration of a method 400 for data-limited mobile radio communication by means of an integrated subscriber identity module 150 and counter 170 according to the disclosure.
