Description

The present invention relates to a mobile radio communication device with two integrated subscriber identity modules and a method for mobile radio communication by means of two integrated subscriber identity modules.

Cellular networks have been installed in order to provide the network subscriber with a variety of services. Different network operators offer different services in different versions and at different prices. There are therefore many reasons to use more than one SIM card in the same mobile communications device, in particular to separate private and business calls, avoiding a SIM card change when abroad and the targeted use of different tariffs, such as telephone calls. and flat-rate data tariffs. Cellular communication devices with two SIM cards are particularly popular where there are lower prices for calls between customers of the same provider. Such devices enable users to have separate contact lists on each SIM card and do roaming, i.e. the ability of a cellular network subscriber to independently receive or make calls, send and send data in a cellular network other than their home network receiving or having access to other cellular network services is easier.

It is the object of the present invention to create a concept for cellular communication which allows communication over several cellular networks in a simple manner.

In particular, it is the object of the present invention to provide a mobile radio communication device and a method for wireless communication over a plurality of mobile radio networks.

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 specific 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).

Such a cellular communication device facilitates cellular communication over several cellular networks, since two integrated subscriber identity modules are used, which are located in the respective cellular network.

The two integrated subscriber identity modules can communicate via different cellular networks and network technologies, in particular via different network slices of the 5G system architecture, which simplifies communication in different cellular network topologies for the user.

According to an expedient development, the communication interface is designed to send out the control signal with the first binary value to the controller in order to send out the first data, and to send out the control signal with the second binary value to the controller in order to send out the second data.

This offers the technical advantage that the controller can easily recognize whether the first data or the second data are to be sent out. This means that the controller can use the binary signal on the basis of a simple decision, for example on the basis of a comparator, to recognize whether the first integrated subscriber identity module or the second integrated subscriber identity module is currently active.

The communication interface is expediently designed to send the control signal with the first binary value to the controller only if the first data are stored in the first data memory, and to only send the control signal with the second binary value to the control device if the second Data are stored in the second data memory.

This offers the technical advantage that the controller can easily recognize whether first or second data are present, which are then to be transmitted to the first cellular network or the second cellular network.

According to an expedient development, the first data memory has a memory cell and the first data memory is designed to store a binary value in a memory cell of the first data memory to indicate that the first data are stored in the first data memory, and the second data memory has a memory cell and is designed to store a binary value in a memory cell of the second data memory in order to indicate that the second data is stored in the second data memory, and the mobile radio communication interface is designed to read out a content of the respective memory cell.

This offers the technical advantage that the mobile radio communication interface can easily recognize whether the first or second data is already present in the respective memory in order to then signal this to the controller.

The mobile radio communication device expediently comprises a first sensor, which is designed to detect a first value of a first physical variable and to store the first value as the first data in the first data memory, and a second sensor, which is designed to to acquire a second value of a second physical quantity and to store the second value as the second data in the first data memory, the first physical quantity and the second physical quantity being different.

This offers the technical advantage that the mobile radio communication device can store sensor data and transmit them to the respective mobile radio network. The mobile radio communication device can thus be implemented as a loT device, for example, which records sensor data and makes it available to the network.

According to an expedient development, the first data memory is designed to delete the first data after reading out the first data through the communication interface from the first data memory, and the second data memory is designed to delete the second data after reading out the second data by the Delete communication interface from the second data memory.

This offers the technical advantage that the recording duration for the sensor data increases if the memory is deleted again after each transmission, so that no unnecessary data that has already been transmitted is stored in the respective data memory.

The controller is expediently designed to interrupt a voltage supply of the first integrated subscriber identity module in order to deactivate the first integrated subscriber identity module, and to interrupt a voltage supply of the second integrated subscriber identity module in order to deactivate the second integrated subscriber identity module , and the communication interface has an integrated voltage source which is designed to provide the respective voltage supply.

This offers the technical advantage that the respective integrated subscriber identity modules or iSIM modules can be deactivated in a simple manner.

According to an expedient development, the controller is designed to connect the first integrated subscriber identity module to a voltage supply in order to activate the first integrated subscriber identity module, and to connect the second integrated subscriber identity module to a voltage supply in order to connect the second integrated subscriber -Activate the identity module.

This offers the technical advantage that the respective integrated subscriber identity modules or iSIM modules can be activated in a simple manner.

The mobile radio communication device expediently comprises a controllable switch which can be controlled by the controller and is designed to separate the power supply from the first integrated subscriber identity module and at the same time to connect the second integrated subscriber identity module to the power supply, or the power supply to separate from the second integrated subscriber identity module and at the same time to connect the first integrated subscriber identity module to the power supply.

This offers the technical advantage that the respective integrated subscriber identity modules or iSIM modules can be switched on and off in a simple manner. The switch can be used to ensure that only one of the two integrated subscriber identity modules is active while the other is in the deactivated state.

According to an expedient development, the first cellular network is a first subnetwork of a 5G cellular network, and the second cellular network is a second subnetwork of the 5G cellular network, the cellular communication device is a loT communication device, with the first cellular subscriber identifier in the first integrated subscriber identity module is stored cryptographically encrypted using a first public cryptographic key, and wherein the second mobile subscriber identifier is stored cryptographically encrypted in the second integrated subscriber identity module using a second public cryptographic key, the first public cryptographic key dem is assigned to the first cellular network, and wherein the second public cryptographic key is assigned to the second cellular network.

This offers the technical advantage that the respective integrated subscriber identity modules or iSIM modules can be used in 5G communication networks, in particular network slices, in order to transmit data. 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 sharing of functional components across different network slices, etc.

The mobile radio communication device thus supports the three different service categories as provided in the 5G network, that is, Enhanced Mobile Broadband (eMBB), massive machine type communication, mMTC, or loT, and ultra-reliable communication with low latency (UR-LLC).

The cellular communication device 130 has a cellular communication interface 140 for communication with the first cellular network 110 and the second cellular network 120. The communication interface 140 has a first integrated subscriber identity module (iSIM: Integrated Subscriber Identity) 150 and a second integrated subscriber identity module 160. The first integrated subscriber identity module 150 is implemented as an embedded integrated circuit and permanently stores a first cellular subscriber identifier 113 together with the first network identification 111 and a network address 112 of the first cellular network 110 in the first integrated subscriber identity module 150.

Fixed storage means that the first mobile radio subscriber identifier 113, the first network identification 111 and the network address 112 of the first mobile radio network 110 are stored in the first integrated subscriber identity module 150 even when the power supply is switched off. For the second integrated subscriber identity module 160, the fixed storage means that the second cellular subscriber identifier 123, the second network identification 121 and the network address 122 of the second cellular network 120 are stored in the second integrated subscriber identity module 160 even when the power supply is switched off.

The PCF (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 communication interface 140 can, for example, transmit the first data 114 to the UDM 352 block. 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.

The first data 114 and / or the second data 124 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 first integrated subscriber identity module 150 can authenticate itself in the 5G network 300, for example, via the AUSF 351 block. The second integrated subscriber identity module 160 can also authenticate itself in the 5G network 300 via the AUSF entity 351.

The AF (Application Function) entity 351 provides application functions with which certain services can be carried out, for example services which are set up or used by the first integrated subscriber identity module 150 or the second integrated subscriber identity module 160.

The NSSF (Network Slice Selection Function) entity 350 provides functions to select certain network slices. For example, the first integrated subscriber identity module 150 can select a first slice in the 5G communication system 300 and the second integrated subscriber identity module 160 can select a second slice in the 5G communication system 300.

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 corresponding to the specification 3GPP TS 23.501, the terminal is only generally referred to as UE (User Equipment) without the special embodiment shown here in FIG. 3 with two integrated subscriber identity modules iSIM1 and iSIM2. The mobile radio communication device 130 or UE is connected either to a radio access network (Radio Access Network, RAN) 331 or an access network (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 new RAT and advanced LTE technologies, while the AN 331 is a general base station with non-3GPP access, e.g. WiFi. The next generation core network or the 5G communication system 300 shown in FIG. 3 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 ( EX) 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, for example, to a single AMF 340, 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 a first network identification 111 and a first network address 112, as described above for FIG. 2 and is responsible for terminating and / or terminating the messages or communication requests of the first integrated subscriber identity module 150 of the mobile radio communication interface 140 to initiate a communication of the first integrated subscriber identity module 150 in the first cellular network 110.

The AMF 340 can also process the messages or communication requests of the second integrated subscriber identity module 160 of the cellular communication interface 140 and forward them to the second cellular network 120, for example via the mechanisms as described below for FIG of the second integrated subscriber identity module in the second cellular network 120.

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 UPF 332 with regard to the data transfer, for example for the transfer of the first data 114. If a mobile radio communication device 130 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 PCF 342, which is responsible for policy control, in order to ensure the Quality of Service (QoS). Based on this information, PCF 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 132 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 mobile radio communication device 130. N8 308 and N10 310 are defined because the subscription data of the mobile radio communication device 130 are 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. 3 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, “local breakout”). The structures that support roaming and the corresponding session management in accordance with the concept presented here are described in more detail in FIG.

4 shows a schematic illustration of a mobile radio communication device 130 according to the disclosure in a 5G communication system 400 with two exemplary network slices 410, 440 according to an exemplary embodiment.

In particular, the 5G communication network 400 is divided into a first network slice 440, corresponding to the first cellular network 110 according to FIGS. 1 and 2, and a second network slice 410, corresponding to the second cellular network 120 according to FIGS. 1 and 2 Both network slices 440, 410 have the same structure as generally described above for FIG. 3, although not all network elements are shown in detail for the sake of clarity. In particular, the first network slice 440 comprises an access and mobility management network element 451, which has the same functionality and the same interfaces as the AMF entity 340 described above in relation to FIG.

The first network slice 440 can also be a home network slice of the first integrated subscriber identity module 150 and a visited network slice of the second integrated subscriber identity module 160, while the second network slice 410 is a home network slice of the second integrated subscriber identity module 150 and a visited network slice of the first integrated subscriber identity module 150.

The first network slice 440 is, for example, the network slice in which the first integrated subscriber identity module 150 or the user of this module 150 is registered, that is to say in which he has concluded a contract with the network operator.

The second network slice 410 is, for example, the network slice in which the second integrated subscriber identity module 160 or the user of this module 160 is registered, that is to say in which he has concluded a contract with the network operator. Usually this is the same user who has acquired two subscriber identity modules.

The first network slice 440 further comprises a session management network element 452, which has the same functionality and the same interfaces as the SMF entity 341 described above with regard to FIG. 3. The first network slice 440 further comprises a database 460 with the network elements authentication server 461, data manager 462 and policy control 463, which have the same functionality and the same interfaces as the network elements AUSF 351, UDM 352 and PCF 342 described above for FIG .

The same network elements, with the same functionalities and interfaces, also comprise the second network slice 410, that is to say an access and mobility management network element 421, a session management network element 422 and a database 430 with the network elements authentication server 431, data manager 432 and policy control 433.

In the first network slice 440, the network access entity 451 is arranged, which serves to enable the communication connection to be set up. The mobile radio communication device 130 is connected to the network access entity 451 via the N1 interface, also generally referred to here as a specific or dedicated interface for the communication device 130. The network access entity 451 is connected to individual network elements of the second network slice 410 and the first network slice 440 via various communication interfaces, as already described above in FIG. 3: The network access entity 451 is connected to the communication device 130 via the N1 interface connected. The network access entity 451 is connected to the network access entity 421 of the second network slice 410 via an A1 interface, also called a specific or dedicated interface.

The message from the first integrated subscriber identity module 150 with the first mobile radio subscriber identifier 113, the first network identification 111 and the network address 112 of the first mobile radio network 110 is received by the network access entity 451 via the N1 interface. The network access entity 451 then provides the communication interface 140 of the mobile radio communication device 130 with all the necessary data for network access via the N1 interface. The network access entity 451 can, for example, query network capabilities of the first network slice 440 from the database 460 of the first network slice 440 via the N8, N12, N15, N22 interfaces in accordance with the system architecture described in FIG the A1 interface 406 query subscriber data 406 of the mobile radio communication device 130 via the network access entity 421 from the second network slice 410 of the mobile radio communication device 130.

The message from the second integrated subscriber identity module 160 with the second mobile radio subscriber identifier 123, the second network identification 121 and the network address 122 of the second mobile radio network 120 is also received by the network access entity 451 via the N1 interface. The network access entity 451 then provides the communication interface 140 of the mobile radio communication device 130 with all the necessary data for network access via the N1 interface. The network access entity 451 can, for example, query network capabilities of the first network slice 440 from the database 460 of the first network slice 440 and the communication interface 140 of the network via the N8, N12, N15, N22 interfaces in accordance with the system architecture described in FIG Provide mobile communication device 130 available. The network access entity 451 can also use the A1 interface 406 to query subscriber data, the network address of the second network slice 410 and the network identification of the second network slice 410 from the network access entity 421 of the second network slice 410 and the communication interface 140 of the mobile radio communication device 130 available. As an alternative, the network access entity 451 can also direct these queries directly to the database 430 of the second network slice 410 and receive them from there directly, that is to say without a detour via the network access entity 421. The second integrated subscriber identity module 160 can then compare this data with the data of the network address 122 of the second cellular network 120 and the second network identification 121 permanently stored on the second integrated subscriber identity module 160 and, if they match, initiate a communication connection with the second network slice 410 .

The registration request comprises the first mobile radio subscriber identifier of the first integrated subscriber identity module 150. The registration request is transmitted to the network access entity 451 via the specific or dedicated communication interface, that is to say the N1 interface.

In a further step, the network access entity 451 then asks subscriber-specific registration data of the first integrated subscriber identity module 150 from the database 460 of the first network slice 440 or from an external database, based on the first mobile subscriber identifier of the first integrated subscriber identity module 150.

The network access data for the access of the first integrated subscriber identity module 150 to the first network slice 440 are then transmitted by the network access entity 451 to the first integrated subscriber identity module 150 via the specific communication interface N1 and the communication interface 140 of the mobile radio. Communication device 130 transmitted, based on the subscriber-specific registration data of the first integrated subscriber identity module 150.

The specific service can be provided by the first network slice 440 based on the identification of the specific service if the first network slice 440 supports the specific service. Otherwise, that is, if it does not support the specific service, the network access entity 451 can transmit a network slice ID of another mobile radio network to the first integrated subscriber identity module 150 which supports the specific service. In this case, the network slice ID of a further network slice, which can be allocated by the first network slice 440 or to which the first network slice 440 can establish a communication connection, can be transmitted to the first integrated subscriber identity module 150 which supports the specific service.

The registration request 203 can furthermore comprise a key for authenticating the first integrated subscriber identity module 150. The network access entity 451 can authenticate the first integrated subscriber identity module 150 via an authentication entity 461 of the first network slice 440 based on the key. This can be done before the participant-specific registration data is queried.

In detail, the method for establishing the communication connection via the network access entity 451 with the second integrated subscriber identity module 160 can run as follows: In a first step, a registration request is sent from the second integrated subscriber identity module 160 to the network access Entity 451 of the first network slice 440, as already described above for setting up the communication connection with the first integrated subscriber identity module 150. The registration request comprises the second mobile radio subscriber identifier 123 of the second integrated subscriber identity module 160. The registration request is transmitted to the network access entity 451 via the specific communication interface, that is to say the N1 interface.

In a further step, the network access entity 451 then asks subscriber-specific registration data of the second integrated subscriber identity module 160 via the network access entity 421 from the database 430 of the second network slice 410 via the specific A1 interface 406 or from an external one Database, based on the second mobile radio subscriber identifier 123 of the second integrated subscriber identity module 160.

The network access data for the access of the second integrated subscriber identity module 160 to the second network slice 410 are then transmitted by the network access entity 451 to the second integrated subscriber identity module 160 via the dedicated communication interface N1 and the communication interface 140 of the mobile radio. Communication device 130 transmitted, based on the subscriber-specific registration data of the second integrated subscriber identity module 160.

Finally, the communication connection is established by the second integrated subscriber identity module 160 and the corresponding network elements of the first network slice 440 and of the second network slice 410 based on the network access data.

The network access data can, for example, indicate the following capabilities of the second network slice 410: Number and type of further network slices which can be allocated by the second network slice 410 or to which the second network slice can establish a communication connection, Support of specific network slice functions, the ability to transmit data and / or voice, support of 2G / 3G, 4G and / or 5G roaming, support of a specific service through the second network slice 410.

The registration request can furthermore have an identification of a specific service for which the second integrated subscriber identity module 160 requests the second network slice 410. The specific service can be provided by the second network slice 410 based on the identification of the specific service if the second network slice 410 supports the specific service. Otherwise, that is, if it does not support the specific service, the network access entity 451 can transmit a network slice ID of another cellular network to the second integrated subscriber identity module 160 which supports the specific service. In this case, the network slice ID of a further network slice, which can be allocated by the second network slice 410 or to which the second network slice can establish a communication connection, can be transmitted to the second integrated subscriber identity module 160 which supports the specific service.

The registration request can further comprise a key for authenticating the second integrated subscriber identity module 160.
