Description

description

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

Cellular networks 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 a number of reasons for using more than one SIM card in the same mobile radio communication device, in particular for separating private and business calls, for avoiding a SIM card change when traveling abroad and for the targeted use of different tariffs, such as telephone - and data flat rates ("flat rate"). Cellular communication devices with multiple SIM cards are popular, for example, where there are lower prices for calls between customers of the same cellular network operator. Such devices with multiple SIM cards allow users to have separate contact lists on each Providing a SIM card and simplifying roaming, i.e. the ability of a cellular network subscriber to independently receive and make calls, send and receive data or gain access to other cellular network services in a cellular network other than his home network.

Devices with multiple SIM cards are also increasingly 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 relevant information from the real world and to link it with one another For this purpose, communication networks based on the 5G system architecture are increasingly being used, as outlined, for example, in the specification 3GPP TS 23.501.

It is the object of the present invention to create a concept for a mobile radio communication, which allows the communication of human-to-human, human-to-machine and / or machine-to-machine over several mobile radio networks in a simple manner.

In particular, it is the object of the present invention to provide a mobile radio communication device which can communicate via different mobile radio networks and network technologies, in particular via different network slices of the 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).

According to a first aspect, the invention relates to a cellular communication device for wireless communication via a first cellular network and via a second cellular network, wherein the first cellular network has a first network identification and wherein the second cellular network has a second network identification, with the following features: a Mobile radio communication interface for communication with the first mobile radio network and the second mobile radio network, the communication interface having a first integrated subscriber identity module (iSIM: Integrated Subscriber Identity) and a second integrated subscriber identity module, the first integrated subscriber identity module as an embedded integrated Circuit is implemented and permanently stores a first mobile radio subscriber identifier together with the first network identification and a network address of the first mobile radio network, the second inte The integrated subscriber identity module is implemented as an embedded integrated circuit and permanently stores a second cellular subscriber identifier together with the second network identification and a network address of the second cellular network, the first cellular subscriber identifier identifying the first integrated subscriber identity module in the first cellular network, and wherehe second mobile radio subscriber identifier identifies the second integrated subscriber identity module in the second mobile radio network; a first data memory which is set up to store first data; a second data memory which is set up to store second data; a controller which is designed to generate a first control signal at predetermined times of a first time scheme and to generate a second control signal at predetermined times of a second time scheme; wherein the communication interface is designed, in response to the activation of the first integrated subscriber identity module at the predetermined times of the first time scheme, to read out the first data from the first data memory, the first mobile radio subscriber identifier, the first network identification and the network address of the first mobile radio network from the first read out integrated subscriber identity module and send out the first cellular subscriber identifier together with the first network identification, the network address of the first cellular network and the first data to the network address of the first cellular network; and wherein the communication interface is designed, in response to the activation of the second integrated subscriber identity module at the predetermined times of the second time scheme, to read out the second data from the second data memory, the second mobile radio subscriber identifier, the second network identification and the network address of the second mobile radio network from the second integrated Read out subscriber identity module and send out the second mobile radio subscriber identifier together with the second network identification and the network address of the second mobile radio network and the second data to the network address of the second mobile radio network.

Such a cellular communication device facilitates cellular communication from person-to-person, person-to-machine and / or machine-to-machine over multiple cellular networks, since two integrated subscriber identity modules (iSIMs) are used, which are time-division multiplexed operate. These iSIMs can be located in the respective cellular network, for example.

The two integrated subscriber identity modules can communicate via different cellular networks and network technologies, such as different network slices of the 5G system architecture, which simplifies communication in different cellular network topologies for the user. Both the human user and the machine behind which there is a human user who is responsible for the operation of the machine or who is assigned to the respective machine should be referred to as the user.

The two time schemes can indicate times at which the two subscriber identity modules are switched to active in order to upload their respective data to the corresponding cellular network. For example, the mobile communication device can be a loT (Internet of Things) UE that records corresponding measured values for two different subscribers who are assigned to the subscriber identity modules and uploads them to the corresponding cellular network in accordance with the respective time schemes.

In an exemplary embodiment of the mobile radio communication device, the controller is designed to randomly generate random times as the predetermined times of the first time scheme, and the controller is also designed to randomly generate further random times than the predetermined times of the second time scheme.

This offers the technical advantage that the activation of the two subscriber identity modules follows a probability distribution, so that a uniform load distribution can be guaranteed over time.

In an exemplary embodiment of the mobile radio communication device, the controller is designed to replace random times of the second time scheme, which are the same as random times of the first time scheme, by further randomly generated times.

This offers the technical advantage that the two subscriber identity modules are not active at the same time and there can be no overload on the cellular communication interface and the two cellular communication networks.

In an exemplary embodiment of the mobile radio communication device, the number of times is always the same.

This offers the technical advantage that both subscriber identification modules are treated fairly, that they can transmit their data to the respective cellular network at the same number of times.

In an exemplary embodiment of the mobile radio communication device, the mobile radio communication device 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 detect a second value of a second physical variable and to store the second value as the second data in the second data memory, the first physical variable and the second physical variable 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.

In an exemplary embodiment of the mobile radio communication device, the first sensor is a temperature sensor and the second sensor is a pressure sensor.

This offers the technical advantage that various physical quantities can be measured via the one mobile radio communication device and made available to the network. For example, a household appliance, such as a washing machine, can be monitored with it. Or the condition of a tire of a vehicle can be monitored in terms of tire pressure and temperature.

In an exemplary embodiment of the mobile radio communication device, the controller is designed to activate the first sensor at the predetermined times of the second time scheme and the second sensor at the predetermined times of the first time scheme.

This offers the technical advantage that you can work alternately. This enables the first sensor to record its data when the second sensor is currently transmitting its recorded data and vice versa. This enables a particularly efficient way of working.

This offers the technical advantage that the mobile radio channel can be implemented with a small bandwidth if the two sensors share the channel for data transmission.

In an exemplary embodiment of the mobile radio communication device, the controller is configured to connect the first sensor to a voltage source at the predetermined times of the second time scheme in order to activate the first sensor, and the controller is further configured to connect the second sensor to the predetermined ones To connect times of the first time scheme to the voltage source in order to activate the second sensor.

This offers the technical advantage that the respective integrated subscriber identity modules or iSIM modules can be activated and deactivated in a simple manner. It can thus be ensured that both sensors are only active at the predetermined times in their time scheme.

In an exemplary embodiment of the mobile radio communication device, 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 to delete second data from the second data memory through the communication interface.

This offers the technical advantage that the recording time 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.

In an exemplary embodiment of the mobile radio communication device, the communication interface has an integrated voltage source, and the controller is designed to connect the first integrated subscriber identity module to the integrated voltage source in order to activate the first integrated subscriber identity module, and the second to connect the integrated subscriber identity module to the integrated voltage source in order to activate the second integrated subscriber identity module.

This offers the technical advantage that the respective integrated subscriber identity modules can be connected to the integrated voltage source in a simple manner in order to activate or deactivate them. The integrated voltage source enables activation and deactivation to take place particularly quickly and efficiently, as the lines are short.

In an exemplary embodiment of the mobile radio communication device, the communication interface has a transmission unit, the transmission unit being designed to send the first mobile radio subscriber identifier together with the first network identification to the network address of the first mobile radio network, and the second mobile radio subscriber identifier together with the to send out the second network identification to the network address of the second mobile radio network.

This offers the technical advantage that the transmitting unit can initiate communication with the two mobile radio networks in order to inform the respective mobile radio networks about the respective mobile radio subscriber IDs.

In an exemplary embodiment of the cellular communication device, 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, 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, wherein, 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 SG network, that is, Enhanced Mobile Broadband (eMBB), massive machine type communication, mMTC, or loT, and ultra-reliable communication with low latency (UR -LLC).

According to a second aspect, the invention relates to a method for wireless communication over a first cellular network and a second cellular network, the first cellular network having a first network identification and the second cellular network having a second network identification, with the following steps: generating a first Control signal at predetermined times of a first time scheme and generating a second control signal at predetermined times of a second time scheme by a controller of a mobile radio communication device; in response to activation of the first integrated subscriber identity module at the predetermined times of a first time scheme: reading out first data from a first data memory of the mobile radio communication device, reading out a first mobile radio subscriber identifier, a first network identification and a network address of the first mobile radio network from a first integrated Subscriber identity module, iSIM: Integrated Subscriber Identity, and sending the first mobile radio subscriber identifier together with the first network identification, the network address of the first mobile radio network and the first data to the network address of the first mobile radio network; and in response to activation of the second integrated subscriber identity module at the predetermined times of a second time scheme: reading out second data from a second data memory of the mobile radio communication device, reading out a second mobile radio subscriber identifier, a second network identification and a network address of the second mobile radio network from a second integrated subscriber identity module and sending out the second cellular subscriber identifier together with the second network identification, the network address of the second cellular network and the second data to the network address of the second cellular network, the first data being stored in the first data memory of the cellular communication device; wherein the second data are stored in the second data memory of the mobile radio communication device; wherein the first mobile radio subscriber identification together with the first network identification and the network address of the first mobile radio network are permanently stored in the first integrated subscriber identity module; wherein the second mobile radio subscriber identification together with the second network identification and the network address of the second mobile radio network are permanently stored in the second integrated subscriber identity module; wherein the first integrated subscriber identity module is implemented as an embedded integrated circuit, and wherein the second integrated subscriber identity module is implemented as an embedded integrated circuit, wherein the first cellular subscriber identity identifies the first integrated subscriber identity module in the first cellular network, and wherein the second cellular subscriber identifier identifies the second integrated subscriber identity module in the second cellular network.

Such a method facilitates cellular communication from man-to-man, man-to-machine and / or machine-to-machine over multiple cellular networks, since two integrated subscriber identity modules (iSIMs) are used for communication, which in the Time division multiplex can be operated. These iSIMs can be located in the respective cellular network, for example.

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

1 shows a schematic illustration of a cellular radio communication system 100 according to an exemplary embodiment with a cellular radio communication device 130 according to the disclosure.

The mobile radio communication system 100 comprises a first mobile radio network 110 and a second mobile radio network 120 as well as a mobile radio communication device 130 with two integrated subscriber identity modules (iSIM: Integrated Subscriber Identity) 150, 160 and a communication interface 140.

The first mobile radio network 110 is identified by a first network identification 111 and can be addressed by a first network address 112. For example, a network access entity is present in the first mobile radio network 110 which regulates the access to the first mobile radio network 110 and can be addressed via the first network address 112. This network access entity knows the network identification 111 of the first cellular network 110 and can manage access to the first cellular network 110.

The second cellular network 120 is identified by a second network identification 121 and can be addressed by a second network address 122. For example, there is a network access entity in the second cellular network 120 which regulates access to the second cellular network 120 and can be addressed via the second network address 122. This network access entity knows the network identification 121 of the second cellular network 120 and can manage access to the second cellular network 120.

The network access entities for the first and second mobile radio networks 110, 120 can be, for example, RAN (Radio Access Network) entities, such as base stations and radio access entities or AMF (Access and Mobility Management Function) in the 5G network.

The mobile radio communication device 130 comprises two integrated subscriber identity modules, the first integrated subscriber identity module 150 being used for communication via the communication interface 140 with the first mobile radio network 110 and the second integrated subscriber identity module 160 being used for communication via the communication interface 140 with the second Cellular network 120.

The process for establishing communication via the first integrated subscriber identity module 150 with the first mobile radio network 110 and for establishing communication via the second integrated subscriber identity module 160 with the second mobile radio network 120 is described in detail below in relation to FIG.

The communication system 100 is shown here only as an example. It can also include further cellular networks, for example a third or further cellular networks, which can be constructed similarly to the first and second cellular networks 110, 120. Furthermore, networks with other radio access technologies can also be implemented in addition to or instead of the first and second mobile radio networks 110, 120, for example WLAN or WiFi networks.

FIG. 2 shows a schematic illustration of a mobile radio communication device 130 according to the disclosure in the mobile radio communication system 100 of FIG. 1.

As already described above for FIG. 1, the mobile radio communication system 100 comprises a first mobile radio network 110 and a second mobile radio network 120 as well as the mobile radio communication device 130 with two integrated subscriber identity modules (ISIM: Integrated Subscriber Identity) 150, 160 and a communication interface 140.

The mobile radio communication device 130 is used for wireless communication via the first mobile radio network

110 and via the second cellular network 120. The first cellular network 110 has a first network identification

111 and the second cellular network 120 has a second network identification 121.

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 mobile radio subscriber identifier 113 together with the first network identification 111 and a network address 112 of the first mobile radio network 110 in the first integrated subscriber identity module 150. Identity module 160 is implemented as an embedded integrated circuit and permanently stores a second mobile radio subscriber identifier 123 together with the second network identification 121 and a network address 122 of the second mobile radio network 120 in the second integrated subscriber identity module 160.

The 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 also stored in the second integrated subscriber identity module 160 when the power supply is switched off.

The first mobile radio subscriber identifier 113 identifies the first integrated subscriber identity module 150 in the first mobile radio network 110 and the second mobile radio subscriber identifier 123 identifies the second integrated subscriber identity module 160 in the second mobile radio network 120.

The first mobile radio subscriber identifier 113 is, for example, an identifier of the subscriber in the first mobile radio network 110, for example an IMSI (International Mobile Subscriber Identity, i.e. a number for the unique identification of network subscribers in the first mobile radio network 110. Subscriber ID

113 can include parameters for identifying and authenticating the subscriber in the first cellular network 110.

In an analogous manner, the second cellular subscriber identifier 123 is, for example, an identifier of the subscriber in the second cellular network 120, for example an IMSI (International Mobile Subscriber Identity, i.e. a number for the unique identification of network subscribers in the second cellular network 120 Mobile radio subscriber identifier 123 can include parameters for identifying and authenticating the subscriber in the second mobile radio network 120.

The mobile radio communication device 130 furthermore has a first data memory 180 which is set up to store first data 114 and a second data memory 190 which is set up to store second data 124.

The first data 114 can be assigned to the first subscriber identity module 150. For example, the first data 114 can be data that can no longer be stored in the first subscriber identity module 150 and are therefore swapped out to the first data memory 180. This can be, for example, measured values that were measured by the first subscriber identity module 150, for example recorded images or voice data, or temperature values, pressure values, level values, currents, voltage values, etc. The second data 124 can also be sent to the second subscriber identity module 160 must be assigned. For example, the second data 114 can be data that can no longer be stored in the second subscriber identity module 160 and are therefore swapped out to the second data memory 190. This can be, for example, measured values, as already described above for the first subscriber identity module 150, for example recorded image or voice data, or temperature values, pressure values, level values, currents, voltage values, etc.

The first data memory 180 can have a memory cell and be designed to store a binary value in a memory cell of the first data memory 180 in order to indicate that the first data 114 are stored in the first data memory 180. The second data memory 190 can likewise have a memory cell and be designed to store a binary value in a memory cell of the second data memory 190 in order to indicate that the second data 124 is stored in the second data memory 190. The mobile radio communication interface 140 can be designed to read out a content of the respective memory cell.

The memory cells of the two data memories 180, 190 can be flags, for example, which indicate whether the respective data is present in the corresponding data memory 180, 190.

Furthermore, the mobile radio communication device 130 has a controller 170 which is designed to generate a first control signal 171 at predetermined times 173 of a first time scheme 174 and to generate a second control signal 172 at predetermined times 175 of a second time scheme 176. For example, the predetermined times 173, 175 can be determined using a time base, for example a clock, which can be implemented in the controller 170 or in the mobile radio communication device 130. Alternatively, the time base can also be fed to the mobile radio communication device 130 from the outside, for example via a reference signal or a paging signal. The predetermined points in time 173, 175 can be, for example, points in time at which the mobile radio communication device 130 is woken up from a sleep mode in order to perform certain activities, for example the transmission of measurement data or the actuation of actuators.

The communication interface 140 is designed in response to an activation of the first integrated subscriber identity module 150 at the predetermined times 173 of the first time scheme 174, the first data

114 from the first data memory 180, the first mobile radio subscriber identifier 113, the first network identification 111 and the network address 112 of the first mobile radio network 110 to be read from the first integrated subscriber identity module 150 and the first mobile radio subscriber identifier 113 together with the first network identification 111, the network address 112 of the first cellular network 110 and the first data 114 to the network address 112 of the first cellular network 110.

Furthermore, the communication interface 140 is designed to read the second data 124 from the second data memory 190, the second mobile radio subscriber identifier 123, the second network identification, in response to an activation of the second integrated subscriber identity module 160 at the predetermined times 175 of the second time scheme 176 121 and the network address 122 of the second cellular network 120 from the second integrated subscriber identity module 160 and the second cellular subscriber identifier 123 together with the second network identification 121 and the network address 122 of the second cellular network 120 and the second data 124 to the network address 122 of the second cellular network 120 to send out.

The controller 170 can be designed to randomly generate random points in time as the predetermined points in time 173 of the first time scheme 174, and further random points in time as the predetermined points in time 175 of the second

Generate timing schemes 176 randomly. The controller 170 can comprise a random generator which can generate the random points in time and the further random points in time.

The controller 170 can also replace random times of the second time scheme 176, which are the same as random times of the first time scheme 174, with further randomly generated times. This ensures that the two subscriber identity modules 150, 160 are activated at different times and are active at different time intervals. The number of random points in time can be the same for the first and the second subscriber identity module 150, 160, for example.

However, the number of predetermined times 173 of the first time scheme 174 and the number of predetermined times 175 of the second time scheme 176 can also be weighted here. For example, a subscriber identity module that has a particularly large amount of data to transmit, e.g. the first subscriber identity module 150, can receive a longer period of time to transmit the data to the respective cellular network than another subscriber identity module that has less data to transmit, e.g. the second subscriber identity module 160. For example, video data from a surveillance camera can be made available on the communication interface 140 with a greater bandwidth than a status detection system, which displays and reports the status of a component.

The controller 170 can further prioritize or prefer one subscriber identity module over the other subscriber identity module. For example, the controller can be designed to generate the first control signal 171 both at the predetermined times 173 of the first time scheme 174 and at the predetermined times 175 of the second time scheme 176, so that only the first subscriber identity module 150 sends out its first data 114 . This prioritization can last for a certain period of time and then revert to the normal state of nonexistent prioritization. The prioritization can take place, for example, for an emergency call or an emergency response and the controller can be communicated via the communication interface through the first or second mobile radio network 110, 120.

The mobile radio communication device 130 can have a first sensor which can be designed to detect a first value of a first physical variable and to store the first value as the first data 114 in the first data memory (180). The mobile radio communication device 130 can have a second sensor which can be designed to detect a second value of a second physical variable and to store the second value as the second data 124 in the second data memory 190. The first physical variable and the second physical variable can be different.

Alternatively, the first physical variable and the second physical variable can be the same, for example in the case of a redundant measurement by the first integrated subscriber identity module 150 and the second integrated subscriber identity module 160.

For example, the first sensor can be a temperature sensor and the second sensor can be a pressure sensor.

The controller 170 can be designed to activate the first sensor at the predetermined times 175 of the second time scheme 176 and the second sensor at the predetermined times 173 of the first time scheme 174. In this embodiment it is possible to work alternately, that is, the first sensor measures data while the second sensor transmits its previously measured data to the second cellular network 120 via the communication interface 140 or vice versa.

The controller 170 can be designed to connect the first sensor to a voltage source at the predetermined times 175 of the second time scheme 176 in order to activate the first sensor. The controller 170 can also be designed to connect the second sensor to the voltage source at the predetermined times 173 of the first time scheme 174 in order to activate the second sensor. Here, too, work is carried out alternately, that is, the second sensor is activated when the communication interface 140 reads the first data 114 of the first sensor from the first data memory 180 and transmits it to the first cellular network 110 and the first sensor is activated when the communication interface 140 reads out the second data 124 of the second sensor from the second data memory 190 and transmits it to the second cellular network 120.

The first data memory 180 can be designed to delete the first data 114 after the first data 114 has been read out by the communication interface 140 from the first data memory 180, and the second data 124 after the second data 124 has been read out by the communication interface 140 from the second data memory 190 to delete.

The communication interface 140 can have an integrated voltage source, for example, and the controller 170 can be designed to connect the first integrated subscriber identity module 150 to the integrated voltage source in order to activate the first integrated subscriber identity module 150 and the second integrated subscriber identity module 150. To connect the identity module 160 to the integrated voltage source in order to activate the second integrated subscriber identity module 160.

The communication interface 140 can have a transmission unit which can be designed to send the first mobile radio subscriber identifier 113 together with the first network identifier 111 to the network address 112 of the

first mobile radio network 110, and to send out the second mobile radio subscriber identifier 123 together with the second network identification 121 to the network address 122 of the second mobile radio network 120.

The first cellular network 110 can be, for example, a first subnetwork or slice of a 5G cellular network. The second cellular network 120 can be a second subnetwork or slice of the 5G cellular network, as described in more detail below for FIGS. 3 and 4, for example.

The cellular radio communication device 130 can be, for example, a loT (Internet of Things) communication device.

The first mobile radio subscriber identifier 113 can be stored in the first integrated subscriber identity module 150 in a cryptographically encrypted manner using a first public cryptographic key. The second mobile radio subscriber identifier 123 can be stored in cryptographically encrypted form in the second integrated subscriber identity module 160 using a second public cryptographic key. The first public cryptographic key can be assigned to the first cellular network 110, and the second public cryptographic key can be assigned to the second cellular network 120.

The mobile radio communication device 130 can furthermore comprise a first actuator or an interface to a first actuator, which is designed to derive or read out and to a control command for controlling the first actuator from the first data 114 in the first data memory 180 to forward the predetermined times 173 of the first time scheme 174 to the first actuator or the interface to the first actuator in order to move the first actuator at the predetermined times 173 of the first time scheme 174 accordingly. For example, a first robot can carry out a predetermined activity at the predetermined times 173 of the first time scheme 174.

The mobile radio communication device 130 can furthermore comprise a second actuator or an interface to a second actuator, which is designed to derive or read out a control command for controlling the second actuator from the second data 124 in the second data memory 190 at the predetermined times 175 of the second time scheme 176 to the second actuator or the interface to the second actuator in order to move the second actuator at the predetermined times 175 of the second time scheme 176 accordingly.

For example, a second robot can perform a predetermined activity at the predetermined times 175 of the second time scheme 176. For example, the second robot can collaborate with the first robot and perform a coordinated activity. The first robot can grab a component from a supply and move it into a specific position, which the second robot can then attach to an object, for example a car to be manufactured. A production line can thus be programmed in which not only two robots but a plurality of robots and / or machines are controlled in relation to one another over time.

The first and the second actuator can be a machine component which can be controlled by the first 114 and second data 124, respectively. The actuators can be household appliances, for example, which can be controlled in the automated house or home via the first 114 or second data 124. Alternatively, the first and the second actuator can be, for example, loudspeakers or vibration devices of the mobile radio communication device 130, which can be controlled and activated via the corresponding first 114 or second data 124.

3 shows a schematic illustration of a mobile radio communication device 130 according to the disclosure in a 5G communication system 300 according to an exemplary embodiment according to the 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 user or subscriber, that is, the person and / or the machine, in order to initiate communication in the 5G network means to start a communication (mobile originating, MO) or to accept it (mobile terminating, MT). The mobile radio communication device 130 can also initiate communication without human 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 UPF (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 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 or from a network slice to another network Slice, as shown in Figure 4, for example.

The first data 114 and / or the second data 124 can thus be sent via the DN 333 from the mobile radio communication device 130 to another mobile radio communication device or other UE or to a corresponding network slice which is assigned to the respective subscriber identity module is to be transmitted.

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, for example, via the block AUSF 351 in the 5G network 300 or in a network slice, as shown in FIG. The second integrated subscriber identity module 160 can also authenticate itself via the AUSF entity 351 in the 5G network 300 or in a network slice, as shown in FIG.

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, for example the first slice 440 according to the illustration in FIG. 4, in the 5G communication system 300 and the second integrated subscriber identity module 160 can select a second slice, for example the second slice 410 accordingly as shown in FIG. 4, 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 3GPP TS 23.501, however, 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 iSIMI and iSIM2. The mobile radio communication device 130 or UE is connected to either a 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 using new RAT (Radio Access Technology) 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 ( 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 a first network identification 111 and a first network address 112, as described above for FIG. 2, and is responsible for 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 To initiate 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 individually to control 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, the PDF 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 from the AMF

340 is controlled. 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 mobile radio communication device 130. N8 308 and N10 310 are defined because the subscription data of the cellular 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 is 340 and the SMF

341 independent functions in the control level. 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 also supports the roaming concept, 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 access other cellular network services to have. There are two types of application scenarios, on the one hand Home Routed (HR), on the other hand local breakout (LBO, "local breakout").

4 shows a schematic representation of a cellular 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, which can correspond to the first cellular network 110 according to FIGS. 1 and 2, and a second network slice 410, which corresponds to the second cellular network 120 according to FIGS 2 can correspond. That is, in the 5G communication network 400, the two cellular networks 110, 120 can be two different network slices 440,

410 act, which can be assigned to different network operators, for example. 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 for FIG.

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 for FIG. 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 POF 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. In particular, the network access entity 451 is connected to the communication device 130 via the N1 interface, in particular to the communication interface 140 of the communication device 130. The network access entity 451 is connected to the network access entity 421 of the second network slices 410 connected.

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, via the N8, N12, N15, N22 interfaces in accordance with the system architecture described in FIG. 3, network capabilities of the first network slice 440 and / or subscriber data of the mobile radio communication device 130 from the database 460 of the first network slice 440 and it can also query network capabilities of the second network slice 410 and / or subscriber data 406 of the mobile radio communication device 130 via the network access entity 421 from the second network slice 410 via the A1 interface 406. If the first subscriber identity module 150 is registered in the first network slice 440, the network access entity 451 can, for example, read out the data from the database 460 of the first network slice 440 or query it from there. If, on the other hand, the first subscriber identity module 150 is registered in the second network slice 410, the network access entity 451 can query or read out the data via the network access entity 421 of the second network slice 410 from the database 430 of the second network slice 410.

The message from the second integrated subscriber identity module 160 with the second mobile radio subscriber identification 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 necessary data for network access via the N1 interface. The network access entity 451 can, for example, query the 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 mobile radio via the N8, N12, N15, N22 interfaces in accordance with the system architecture described in FIG -Communication device 130 available. The network access entity 451 can also query subscriber data, network address of the second network slice 410 and 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 via the A1 interface 406 provide. Alternatively, 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 use this data with the integrated subscriber identity on the second

Module 160, compare permanently stored data of the network address 122 of the second cellular network 120 and the second network identification 121 and, if they match, initiate a communication connection with the second network slice 410.

In detail, the method for establishing the communication connection via the network access entity 451 with the first integrated subscriber identity module 150 can proceed as follows: In a first step, a registration request is sent from the first integrated subscriber identity module 150 to the network access Entity 451 of the first network slice 440. 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 queries 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 radio subscriber ID 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, based on the subscriber-specific registration data of the first integrated subscriber identity module 150.

The network access data indicate the capabilities of the first network slice 440. Finally, the communication connection is established by the first integrated subscriber identity module 150 and the corresponding network elements of the first network slice 440 based on the network access data.

The network access data can, for example, indicate the following capabilities of the first network slice 440: Number and type of further network slices which can be allocated by the first network slice 440 or to which the first network slice can establish a communication connection, support specific network slice functions, the ability to transmit data and / or voice, support for 2G / 3G, 4G and / or 5G roaming, support for a specific service through the first network slice 440.

The registration request can furthermore have an identification of a specific service for which the first integrated subscriber identity module 150 requests the first network slice 440. 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, i.e. 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 can further 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 take place even before the subscriber-specific registration data is queried.

After the communication connection between the first network slice 440 and the first integrated subscriber identity module 150 has been established, the communication interface 140 can transmit the first data 114 to the first network slice 440 at the predetermined times 173 of the first time scheme 174 the first data 114 can be stored in the first network slice 440, for example in the database 460 of the first network slice 440, to which other network elements can access for evaluating the first data 114.

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 establishing the communication connection with the first integrated subscriber identity module 150. The registration request comprises the second mobile radio subscriber identification 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, i.e. 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 database from, and indeed 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 , based on the subscriber-specific registration data of the second integrated subscriber identity module 160.

The network access data indicate the capabilities of the second network slice 410. 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 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 specific network slice functions, the ability to transmit data and / or voice, support for 2G / 3G, 4G and / or 5G roaming, support for 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, i.e. 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 also be transmitted to the second integrated subscriber identity module 160, which the specific service supported.

The registration request can further comprise a key for authenticating the second integrated subscriber identity module 160. The network access entity 451 can authenticate the second integrated subscriber identity module 160 via an authentication entity 431 of the second network slice 410 based on the key.
