Description

Mobile radio communication device comprising two iSIMs and an interface for automatically selecting a network

Technical Field

The invention relates to a mobile radio communication device with two integrated subscriber identity modules and a mobile radio communication interface for automatically selecting a network, and to a method for mobile radio communication by means of the two integrated subscriber identity modules and for automatic network selection by means of the mobile radio communication interface.

Background

Mobile wireless networks are installed to provide various services to network subscribers. Various network operators offer different services of different versions and different prices. Thus, there are many reasons for using multiple SIM cards in the same mobile wireless communication device, particularly to distinguish private phones from business phones, to avoid changing SIM cards during foreign stay, and to use different tariffs for pertinence, such as call and data Flat rate ("Flat rate"). Mobile wireless communication devices having two SIM cards become more popular when users of the same network operator can enjoy lower rates when talking between them. Such devices allow the user to have a separate address book on each SIM card and roam, i.e., mobile wireless network subscribers can more easily and automatically answer or place calls, send and receive data, or access other mobile wireless network services in a mobile wireless network other than their home network.

Devices with multiple SIM cards are also increasingly being used in the IoT (Internet of Things) field to network machines. Such devices not only enable machines to be networked, but also generally enable physical and virtual objects to be networked to each other and to allow them to cooperate with each other through communications. The functionality implemented using "internet of things" technology allows interactions between a person and any electronic system through which the network is connected, as well as between the systems themselves. The goal of the internet of things is to automatically collect relevant information from the real world, correlate the information to each other, and make it available to the network. For this reason, communication networks according to the 5G system architecture are increasingly being used, for example, see the 3gpp TS 23.501 standard overview.

Disclosure of Invention

The object of the present invention is to propose a concept of mobile radio communication allowing to communicate man, man-machine and/or machine-machine in a simple way over a plurality of mobile radio networks.

In particular, it is an object of the present invention to provide a mobile wireless communication device capable of communicating via various mobile wireless networks and network technologies, in particular via various network slices of a 5G system architecture.

The mobile wireless communications devices and communications systems described herein may take on various types. The various elements described may be implemented by software or hardware components and may be manufactured by various techniques. The individual components may include, for example, microprocessors, semiconductor chips, ASICs, signal processors, electro-optical circuits, integrated circuits, and/or passive devices.

The mobile wireless communications devices and mobile wireless networks described herein may include various technologies and network standards, such as compliance with 5G system architecture. The 5G system architecture includes the concept of network slicing, i.e., dividing the communication network into individual segments or slices or subnetworks. Here, a network slice is a form of virtual network architecture, wherein the network architecture is divided into virtual elements that can be linked to each other (also by software). Multiple virtual networks can be built on a common physical infrastructure through the concept of network slicing. These virtual networks may then be adapted to the specific requirements of the application, service, device, customer or operator. Here, each virtual network (network slice) comprises a set of independent logical network functions that support the requirements of the respective application case.

Each of these virtual networks or network slices provides resources and network topology for a particular service and traffic using the corresponding network segment. This allows assigning functions such as speed, capacity, connectivity and coverage to meet specific requirements for each application case, but functional components can also be shared among various network slices. For this purpose, each network slice can acquire management capabilities, which can be controlled by the network operator or the user depending on the application. Network slices can be managed and organized independently.

According to the 5G system architecture, the mobile wireless network described below may be based on a 5G network. Service-oriented 5G networks support very different services, which have very different performance requirements. For example, 5G supports three different service classes: enhanced mobile broadband (emmbb), mass machine-like communication (mctc, also known as IoT, i.e., internet of things), and ultra-reliable and low-latency communication (UR-LLC).

The mobile wireless communications device described below includes a mobile wireless communications interface or simply communications interface that performs many tasks. Such a communication interface may for example comprise a processor responsible for performing the tasks. As used herein, the term "processor" refers to any device (or block or step) that may be used to process a particular task. The processor may be a single processor or a multi-core processor, or may comprise a set of processors, or may comprise a processing mechanism. The processor may process software or firmware or applications, etc.

According to a first aspect, the invention relates to a mobile radio communications device for radio communications via a first mobile radio network having a first network identity and via a second mobile radio network having a second network identity, the mobile radio communications device comprising the following features: a mobile radio communication interface for communication with a first mobile radio network and a second mobile radio network, wherein the communication interface has a first integrated subscriber identity module (iSIM: integrated Subscriber Identity Module) and a second integrated subscriber identity module, wherein the first integrated subscriber identity module is implemented as an embedded integrated circuit and permanently stores a first mobile radio subscriber identifier and a first network identity, wherein the second integrated subscriber identity module is implemented as an embedded integrated circuit and permanently stores a second mobile radio subscriber identifier and a second network identity, wherein the first mobile radio subscriber identifier identifies the first integrated subscriber identity module in the first mobile radio network and the second mobile radio subscriber identifier identifies the second integrated subscriber identity module in the second mobile radio network; a first data store configured to store first data for forwarding to a first mobile wireless network; a second data store configured to store second data for forwarding to a second mobile wireless network; wherein the mobile wireless communication interface is configured to receive a network identification, and wherein the communication interface is further configured to compare the received network identification with at least one of the permanently stored first network identification and the second network identification, and wherein the mobile wireless communication interface is configured to: reading out first data from the first data store and transmitting the first data to the first mobile radio network together with the first mobile radio subscriber identifier when the received network identification corresponds to the first network identification, reading out second data from the second data store and transmitting the second data to the second mobile radio network together with the second mobile radio subscriber identifier when the received network identification corresponds to the second network identification.

Because of the use of two integrated subscriber identity modules, which are associated with or located in respective mobile radio networks, such a mobile radio communication device may enable mobile radio communication over a plurality of mobile radio networks. By receiving network identifications from corresponding mobile radio networks, an automatic selection of networks can be implemented in the mobile radio communications device, which can simplify mobile radio communications while expediting establishment of communications.

Here, the two integrated subscriber identity modules may communicate over various mobile wireless networks and network technologies, and in particular over various network slices of the 5G system architecture, thereby simplifying user communications in various mobile wireless network topologies. The selection of the respective network slice can also be simplified if the respective network slice can use its network identity for the mobile wireless communication device.

In an exemplary embodiment of the mobile radio communication device, the mobile radio communication interface is configured to send the first data together with the first mobile radio subscriber identifier to a network address of the first mobile radio network and to send the second data together with the second mobile radio subscriber identifier to a network address of the second mobile radio network.

This provides the technical advantage that the mobile radio communication device can easily provide the data of the first mobile radio subscriber, i.e. the first data together with the first mobile radio subscriber identifier, to the first mobile radio network by means of the first subscriber identity module. The mobile radio communication device can also easily provide data of the second mobile radio subscriber, i.e. the second data together with the second mobile radio subscriber identifier, to the second mobile radio network by means of the second subscriber identity module. It should be appreciated that the same applies to a plurality of subscribers having respective subscriber identity modules.

In an exemplary embodiment of the mobile wireless communications device, the communications interface is configured to: the first data and the first mobile wireless subscriber identifier are transmitted only when the first data is stored in the first data storage area and the second data and the second mobile wireless subscriber identifier are transmitted only when the second data is stored in the second data storage area.

This provides the technical advantage that the communication interface can easily recognize whether the first data or the second data is present and then send it to the first mobile radio network or the second mobile radio network. This avoids sending meaningless data that is not based on the measurement values.

In an exemplary embodiment of the mobile radio communications device, the first data memory has a memory location and the first data memory is configured to store in the memory location of the first data memory a binary value indicating that the first data is stored in the first data memory and the second data memory has a memory location and is configured to store in the memory location of the second data memory a binary value indicating that the second data is stored in the second data memory and the mobile radio communications interface is configured to read out the content of the respective memory location.

This provides the technical advantage that the mobile radio communication interface can easily recognize whether the first data or the second data is already present in the respective memory for subsequent transmission to the mobile radio communication interface.

In an exemplary embodiment of the mobile wireless communications device, the mobile wireless communications device comprises: a first sensor configured to detect a first value of a first physical quantity and store the first value as first data in a first data memory; and a second sensor configured to detect a second value of a second physical quantity and store the second value as second data in a second data store, wherein the first physical quantity is different from the second physical quantity.

This provides the technical advantage that the mobile radio communications device can store and transmit sensor data to the corresponding mobile radio network. This allows the mobile wireless communication device to be implemented, for example, as an IoT device that records sensor data and is available to the network.

In an exemplary embodiment of the mobile radio communications device, the first data store is configured to delete the first data after the communications interface reads the first data from the first data store, and the second data store is configured to delete the second data after the communications interface reads the second data from the second data store.

This provides the technical advantage that the recording time of the sensor data is prolonged if the memory is deleted after each transmission, whereas by means of the above-mentioned technical means, any unnecessary data already transmitted can be avoided from being stored in the corresponding data memory.

In an exemplary embodiment of the mobile wireless communications device, the mobile wireless communications interface is configured to interrupt voltage feeding to the first integrated subscriber identity module to disable the first integrated subscriber identity module and to interrupt voltage feeding to the second integrated subscriber identity module to disable the second integrated subscriber identity module.

This provides the technical advantage that the respective integrated subscriber identity module or the ikvi module can be disabled in a simple manner.

In an exemplary embodiment of the mobile wireless communications device, the communications interface has an integrated power supply configured to provide a corresponding voltage feed.

This provides the technical advantage that the integrated power supply can quickly provide a corresponding voltage feed for the subscriber identity module, thereby reducing the time to establish a communication connection via the corresponding mobile radio network.

In an exemplary embodiment of the mobile wireless communications device, the communications interface is configured to activate the respective integrated subscriber identity module to transmit the respective data and to disable the respective integrated subscriber identity module after transmitting the respective data.

This provides the technical advantage that the respective integrated subscriber identity module or the ikvi module is only briefly activated to transmit its corresponding data and then disabled. This saves power and extends the standby time of the corresponding subscriber identity module. This is particularly important where the mobile wireless communication device is an IoT device, but it is also an advantage for conventional smartphones or mobile phones to extend battery life.

In an exemplary embodiment of the mobile wireless communications device, the communications interface is configured to: the first integrated subscriber identity module and the second integrated subscriber identity module are disabled, in particular disabled for a long period of time, when the received network identity neither corresponds to the stored first network identity nor to the stored second network identity.

This provides the technical advantage that the corresponding integrated subscriber identity module or the ikvi module is activated only if it can also send its data to the mobile radio network corresponding to its network identity. Especially in large systems with many mobile wireless communication devices (e.g., ioT systems) or mobile wireless communication devices with many subscriber identity modules, situations may arise where each mobile wireless network or network slice transmits a large number of network identifications. It is advantageous that not all subscriber identity modules are awakened when receiving a network identification, but only when or only when receiving a network identification corresponding or associated therewith.

In an exemplary embodiment of the mobile wireless communications device, the mobile wireless communications device includes a controllable switch controllable by the communications interface and configured to switch the first integrated subscriber identity module off the voltage feed while the second integrated subscriber identity module is on the voltage feed, or to switch the second integrated subscriber identity module off the voltage feed while the first integrated subscriber identity module is on the voltage feed.

This provides the technical advantage that the respective integrated subscriber identity module or the ikim module can be switched on and off in a simple manner. The use of a switch ensures that only one of the two integrated subscriber identity modules is in an active state and the other is in a disabled state.

In an exemplary embodiment of the mobile wireless communication device, the first mobile wireless network is a first subnet or first network slice of a 5G mobile wireless network and the second mobile wireless network is a second subnet or second network slice of the 5G mobile wireless network, the mobile wireless communication device is an IoT communication device, wherein the first mobile wireless subscriber identifier is cryptographically encoded in the first integrated subscriber identity module by using a first public encryption key and the second mobile wireless subscriber identifier is cryptographically encoded in the second integrated subscriber identity module by using a second public encryption key, wherein the first public encryption key is associated with the first mobile wireless network and the second public encryption key is associated with the second mobile wireless network.

This provides the technical advantage that data can be transmitted in a 5G communication network, in particular a network slice, using a corresponding integrated subscriber identity module or an ikvi module. The advantage of the 5G system architecture is thus utilized, namely that the virtual network architecture on the common physical infrastructure is specifically adapted to the requirements of applications, services, devices, clients or operators, supporting logical network functions, assigning functions such as speed, capacity, connectivity and network coverage to applications to meet the special requirements of each application situation, and sharing functional components across various network slices, etc.

The mobile wireless communication device supports three different classes of service provided in 5G networks, namely enhanced mobile broadband (eMBB), mass machine class communication (emtc or IoT), and ultra-reliable and low latency communication (UR-LLC)).

According to a second aspect, the invention relates to a method which can be used for wireless communication via a first mobile radio network and via a second mobile radio network, wherein the first mobile radio network has a first network identification, the second mobile radio network has a second network identification, and the method is used for automatically selecting a network via a mobile radio communication interface of a mobile radio communication device, wherein the mobile radio communication interface has a first integrated subscriber identity module (iSIM: integrated Subscriber Identity Module) and a second integrated subscriber identity module, wherein the first integrated subscriber identity module is implemented as an embedded integrated circuit and permanently stores the first mobile radio subscriber identifier together with the first network identification, the second integrated subscriber identity module is implemented as an embedded integrated circuit and permanently stores the second mobile radio subscriber identifier together with the second network identification, wherein the first mobile radio subscriber identifier identifies the first integrated subscriber identity module in the first mobile radio network, the second mobile radio subscriber identifier identifies the second integrated subscriber identity module in the second mobile radio network, wherein the mobile radio communication device has a first data storage configured for storing the first data for forwarding to the first mobile radio network and a second data forwarding to the second radio network, wherein the method comprises the steps of storing the second data: receiving, by the mobile wireless communications interface, a network identification; comparing the received network identity with at least one of the permanently stored first network identity and second network identity; reading first data from the first data store and transmitting the first data to the first mobile radio network along with the first mobile radio subscriber identifier when the received network identifier corresponds to the first network identifier; when the received network identity corresponds to the second network identity, second data is read from the second data store and sent to the second mobile radio network together with the second mobile radio subscriber identifier.

Because two integrated subscriber identity modules are used, which are associated with or located in respective mobile radio networks, this approach enables mobile radio communications over multiple mobile radio networks. By receiving network identifications from corresponding mobile radio networks, an automatic selection of networks can be implemented in the mobile radio communications device, which can simplify mobile radio communications while expediting establishment of communications.

Fig. 1 shows a schematic diagram of a mobile wireless communication system 100 having a mobile wireless communication device 130 according to the present disclosure, according to an exemplary embodiment.

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

The first mobile radio network 110 is identified by a first network identification (ID 1) 111 and is addressable by a first network address 112. For example, there is a network access entity in the first mobile radio network 110 that coordinates access to the first mobile radio network 110 and is addressable via a first network address 112. The network access entity recognizes the network identification 111 of the first mobile radio network 110 and may manage access to the first mobile radio network 110.

The second mobile wireless network 120 is identified by a second network identification (ID 2) 121 and is addressable by a second network address 122. For example, there is a network access entity in the second mobile wireless network 120 that coordinates access to the second mobile wireless network 120 and is addressable via a second network address 122. The network access entity recognizes the network identity 121 of the second mobile radio network 120 and may manage access to the second mobile radio network 120.

The network access entities of the first mobile radio network 110 and the second mobile radio network 120 may be, for example, RAN (Radio Access Network ) entities, such as base stations and radio access entities in a 5G network or AMFs (Access and Mobility Management Function, access and mobility management functions).

The mobile wireless communication device 130 comprises two integrated subscriber identity modules, wherein a first integrated subscriber identity module 150 is for communication with the first mobile wireless network 110 via the communication interface 140 and a second integrated subscriber identity module 160 is for communication with the second mobile wireless network 120 via the communication interface 140.

The process for establishing communication with the first mobile wireless network 110 via the first integrated subscriber identity module 150 and establishing communication with the second mobile wireless network 120 via the second integrated subscriber identity module 160 is described in detail below with reference to fig. 2.

The communication system 100 is shown by way of example only in this figure. Additional mobile wireless networks, such as a third or other mobile wireless network, may also be included, which may be constructed similarly to the first mobile wireless network 110 and the second mobile wireless network 120. Furthermore, networks with other radio access technologies, such as WLAN or WiFi networks, may be implemented in addition to or instead of the first mobile radio network 110 and the second mobile radio network 120.

In addition to the two integrated subscriber identity modules 150, 160 shown in fig. 1, the mobile wireless communication device 130 may also include additional subscriber identity modules that provide access to additional mobile wireless networks. Of course, more than two subscriber identity modules may be present in the mobile wireless communication device 130, which provide access to the same mobile wireless network.

Fig. 2 shows a schematic diagram of a mobile wireless communication device 130 according to the present disclosure in the mobile wireless communication system 100 of fig. 1.

As described above with reference to fig. 1, the mobile radio communication system 100 comprises a first mobile radio network 110 and a second mobile radio network 120 and a mobile radio communication device 130 having two integrated subscriber identity modules (issim) 150, 160 and a communication interface 140.

The mobile wireless communication device 130 is for wireless communication via the first mobile wireless network 110 and via the second mobile wireless network 120. The first mobile radio network 110 has a first network identification 111 and the second mobile radio network 120 has a second network identification 121.

The mobile wireless communication device 130 has a mobile wireless communication interface 140 for communicating with the first mobile wireless network 110 and the second mobile wireless network 120. The communication interface 140 has a first integrated subscriber identity module (iSIM 1) 150 and a second integrated subscriber identity module (iSIM 2) 160. The first integrated subscriber identity module 150 is implemented as an embedded integrated circuit and the first mobile radio subscriber identifier 113 is permanently stored in the first integrated subscriber identity module 150 together with the first network identification 111 of the first mobile radio network 110. The second integrated subscriber identity module 160 is implemented as an embedded integrated circuit and the second mobile radio subscriber identifier 123 is permanently stored in the second integrated subscriber identity module 160 together with the second network identification 121 of the second mobile radio network 120.

Permanent storage represents: the first mobile wireless subscriber identifier 113 and the first network identification 111 are stored in the first integrated subscriber identity module 150 even if power is turned off. For the second integrated subscriber identity module 160, the representation is permanently stored: the second mobile wireless subscriber identifier 123 and the second network identification 121 are stored in the second integrated subscriber identity module 160 even if power is turned off.

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

The mobile wireless communications device 130 has a first data store 180 configured to store first data 114 for forwarding to the first mobile wireless network 110.

The mobile wireless communication device 130 has a second data store 190 configured to store second data 124 for forwarding to the second mobile wireless network 120.

The communication interface 140 is configured to: the network identity is received and compared with at least one of the permanently stored first network identity 111 and second network identity 121 and when the received network identity corresponds to the first network identity 111, the first data 114 is read out of the first data storage 180 and sent to the first mobile radio network 110 together with the first mobile radio subscriber identifier 113.

The communication interface 140 is further configured to: when the received network identity corresponds to the second network identity 121, second data 124 is read out from the second data storage 190 and sent to the second mobile radio network 120 together with the second mobile radio subscriber identifier 123.

The first mobile radio subscriber identifier 113 is for example an identifier of a subscriber in the first mobile radio network 110, such as an IMSI (International Mobile Subscriber Identity ), i.e. a number for uniquely identifying a network subscriber in the first mobile radio network 110. The first mobile wireless subscriber identifier 113 may include parameters for identifying and authenticating a subscriber in the first mobile wireless network 110.

Similarly, the second mobile radio subscriber identifier 123 is for example an identifier of a subscriber in the second mobile radio network 120, such as an IMSI (International Mobile Subscriber Identity ), i.e. a number for uniquely identifying a network subscriber in the second mobile radio network 120. The second mobile wireless subscriber identifier 123 may include parameters for identifying and authenticating the subscriber in the second mobile wireless network 120.

Here, the first data 114 may be associated with the first subscriber identity module 150. For example, the first data 114 may be data that may no longer be stored in the first subscriber identity module 150 and thus transferred to the first data store 180. Such data may relate to, for example, measured values measured by the first subscriber identity module 150, such as recorded image or voice data, or temperature values, pressure values, level values, amperage, voltage values, etc.

Likewise, the second data 124 may be associated with a second subscriber identity module 160. For example, the second data 114 may be data that may no longer be stored in the second subscriber identity module 160 and thus transferred to the second data store 190. Such data may relate to, for example, measured values, such as recorded image or voice data, or temperature values, pressure values, level values, amperage, voltage values, etc., as described above for the first subscriber identity module 150.

The first mobile wireless network 110 may associate the uploaded first data 114 with the first iksim 150 via a first mobile wireless subscriber identifier 113 (e.g., UE ID or IMSI). The second mobile wireless network 120 may associate the uploaded second data 124 with the second iksim 160 via a second mobile wireless subscriber identifier 123 (e.g., UE ID or IMSI). This is very beneficial to upload large amounts of data (e.g., data from several IoT devices) to the network to identify which measurement data comes from which device. In particular, a real-time asynchronous uploading of the first data 114 and the second data 124 to the network may occur. It is important to send the first data 114 along with the first mobile radio subscriber identifier 113 and the second data 124 along with the second mobile radio subscriber identifier 123 so as not to confuse the first data 114 or the second data 124 with other data being transmitted.

The first data 114 may be transmitted together with the first mobile radio subscriber identifier 113, for example by providing the first data 114 with an index corresponding to the first mobile radio subscriber identifier 113. The first data 114 may also be sent as a payload in a data field that enters the first mobile radio subscriber identifier 113 into its header or data header.

Also, the sending of the second data 124 together with the second mobile radio subscriber identifier 123 may be achieved, for example, by providing the second data 124 with an index corresponding to the second mobile radio subscriber identifier 123. The second data 124 may also be sent as a payload in a data field that enters the second mobile radio subscriber identifier 123 into its header or data header.

The communication interface 140 may be configured to send the first data 114 along with the first mobile wireless subscriber identifier 113 to the network address 112 of the first mobile wireless network 110 and the second data 124 along with the second mobile wireless subscriber identifier 123 to the network address 122 of the second mobile wireless network 120.

The mobile wireless communication device 130 may further include a first sensor configured to detect a first value of the first physical quantity and store the first value as the first data 114 in the first data memory 180.

The mobile wireless communication device 130 may include a second sensor configured to detect a second value of the second physical quantity and store the second value as second data 124 in the second data store 190.

Here, the first physical quantity and the second physical quantity may be different. Alternatively or in addition, the first and second physical quantities may be the same, for example in case of redundant measurements by the first integrated subscriber identity module 150 and the second integrated subscriber identity module 160.

The mobile wireless communications device 130 may further include a first actuator or an interface of the first actuator configured to derive or read control commands for controlling the first actuator from the first data 114 in the first data store 180 and forward the control commands to the first actuator or the interface of the first actuator to drive the first actuator, respectively.

The mobile wireless communications device 130 may further include a second actuator or an interface of the second actuator configured to derive or read control commands for controlling the second actuator from the second data 124 in the second data store 190 and forward the control commands to the second actuator or the interface of the second actuator to drive the second actuator, respectively.

The first and second actuators may be machine components controllable by the first and second data 114, 124. The actuator may be, for example, an automation or a smart home or a home appliance in a home controllable via the first data 114 or the second data 124. Alternatively or in addition, the first and second actuators may be, for example, speakers or vibration means of the mobile wireless communication device 130, which may be controlled and activated via the corresponding first and second data 114, 124.

The first data store 180 may be configured to delete the first data 114 from the first data store 180 after the communication interface 140 reads the first data 114.

The second data store 190 may be configured to delete the second data 124 from the second data store 190 after the communication interface 140 reads the second data 124.

The communication interface 140 may be configured to interrupt the voltage feed to the first integrated subscriber identity module 150 to disable the first integrated subscriber identity module 150 and to interrupt the voltage feed to the second integrated subscriber identity module 160 to disable the second integrated subscriber identity module 160. The communication interface 140 may have an integrated power supply configured to provide a corresponding voltage feed.

The communication interface 140 may be configured to activate the respective integrated subscriber identity module 150, 160 to transmit the respective data 114, 124 and to disable the respective integrated subscriber identity module 150, 160 after transmitting the respective data.

The communication interface 140 may be configured to switch on the voltage feed for the first integrated subscriber identity module 150 to activate the first integrated subscriber identity module 150 and switch on the voltage feed for the second integrated subscriber identity module 160 to activate the second integrated subscriber identity module 160.

The mobile wireless communications device 130 may have a controllable switch that may be controlled by the communications interface 140. The controllable switch may be configured to switch the first integrated subscriber identity module 150 off the voltage feed while the second integrated subscriber identity module 160 is on the voltage feed, or to switch the second integrated subscriber identity module 160 off the voltage feed while the first integrated subscriber identity module 150 is on the voltage feed.

The mobile wireless communication interface 140 may be configured to: when the received network identity corresponds neither to the stored first network identity 111 nor to the stored second network identity 121, the first integrated subscriber identity module 150 and/or the second integrated subscriber identity module 160 is disabled, in particular disabled for a long period of time.

The first mobile wireless network 110 may be, for example, a first subnet or slice of a 5G mobile wireless network. The second mobile wireless network 120 may be a second subnet or slice of the 5G mobile wireless network, as described in detail below, for example, with reference to fig. 3 and 4.

The mobile wireless communication device 130 may be, for example, an IoT (Internet of Things) communication device.

The first mobile wireless subscriber identifier 113 may be stored in the first integrated subscriber identity module 150 in an cryptographically encoded manner by using a first public encryption key. The second mobile wireless subscriber identifier 123 may be stored in the second integrated subscriber identity module 160 in an cryptographically encoded manner by using a second public encryption key. Here, a first public encryption key may be associated with the first mobile wireless network 110 and a second public encryption key may be associated with the second mobile wireless network 120.

Fig. 3 shows a schematic diagram of a mobile wireless communication device 130 according to the present disclosure in a 5G communication system 300 (hereinafter also referred to as 5G network 300, or as next generation network) according to an exemplary embodiment conforming to the 3gpp TS 23.501 standard. Fig. 3 schematically illustrates blocks included in such a 5G communication system 300.

The mobile wireless communication device 130 corresponds to a User Equipment (UE) or client terminal that may be operated by a subscriber to initiate a communication in a 5G network, i.e. to start a communication (mobile originating, MO) or to accept a communication (mobile terminating, MT). The mobile wireless communications device 130 may also initiate communications without user interaction, e.g., it may be a machine terminal such as for an automobile, machine, robot or other device.

The (R) AN (radio access network) entity 331 represents a (radio) access network used by the mobile wireless communication device 130 to gain access to the 5G communication network. The interface between the mobile wireless communication device 130 and the (R) AN may be AN air interface when the access network 331 is a wireless network or a wired interface when the access network 331 is a wired network.

The AMF (Access and Mobility Management Function ) entity 340 represents access and mobility management functions to manage access and enable mobility control. AMF 340 may also include a network slice selection function. Mobility management is generally not required for wireless access.

SMF (Session Management Function ) entity 341 represents a session management function. The SMF entity 341 establishes a session and manages the session according to a network policy or network plan.

The UPF (User Plane Function ) entity 332 represents user plane functions. Such user plane functionality may be used in various configurations and locations depending on the type of service.

PCF (Policy Control Function ) entity 342 represents a policy (or planning) control function. PCF entity 342 is used to provide a policy framework that includes network slicing, roaming, and mobility management. This corresponds to the function of PCRF in 4G systems.

The UDM (Unified Data Management), unified data management) entity 352 provides public data management. With this data management, subscriber data and profiles can be saved. This corresponds to the function of HSS in 4G systems but can be used for mobile and wired access in NG Core networks.

The communication interface 140 may, for example, transmit the first data 114 to the block UDM 352. This enables, for example, measurements or measurement parameters recorded by the mobile radio communications device 130 to be stored in the network 300.

DN (Data Network) 333 provides a Data Network through which Data can be transferred, for example, from one mobile wireless communication device 130 to another mobile wireless communication device 130 or UE.

Thus, the first data 114 and/or the second data 124 may be transmitted from one mobile wireless communication device 130 to another mobile wireless communication device or another UE via DN 333.

The AUSF (Authentication Server Function ) entity 351 provides an authentication function that the subscriber or mobile wireless communication device 130 can use to log into the network. The first integrated subscriber identity module 150 may authenticate, for example, via block AUSF 351 in the 5G network 300. The second integrated subscriber identity module 160 may also be authenticated via the AUSF entity 351 in the 5G network 300.

The AF (Application Function ) entity 351 provides application functions with which specific services, such as services set up or used by the first integrated subscriber identity module 150 or the second integrated subscriber identity module 160, can be performed.

NSSF (Network Slice Selection Function ) entity 350 provides the function of selecting a particular network slice. Thus, the first integrated subscriber identity module 150 may, for example, select a first slice in the 5G communication system 300, while the second integrated subscriber identity module 160 may select a second slice in the 5G communication system 300.

The 5G communication system 300 shown in fig. 3 corresponds to a 5G system architecture conforming to the 3gpp TS 23.501 standard, and represents the structure of a NG (Next Generation) network consisting of Network Functions (NF) and reference points connecting NF. In the 3gpp TS 23.501 standard, however, the terminal Equipment is generally specified only by the UE (User Equipment), rather than the specific implementation shown in fig. 3 with two integrated subscriber identity modules, issim 1 and issim 2. The mobile wireless communication device 130 or UE is connected to a radio Access Network (Radio Access Network, RAN) 331 or AN Access Network (AN) 331. The mobile wireless communication device 130 or UE is also connected to an Access and Mobility Function (AMF) 340.RAN 331 represents a base station using a new RAT (Radio Access Technology ) and LTE-advanced technology, while AN 331 represents a general base station with non-3 GPP access, e.g., wiFi. The next generation core network or 5G communication system 300 shown in fig. 3 is composed of various Network Functions (NF). In fig. 3, there are seven next generation cores NF, 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 Plane Function (UPF) 332, and (7) User Data Management (UDM) 352. The integrated subscriber identity module 150, 160 may select one or more network functions from among to initiate communication.

The Network Function (NF) represents a processing function that the 3GPP takes over in the next generation (NextGen or NG). It has both functional behavior and acts as an interface. NF can be implemented as a network element on dedicated hardware, as a software instance, or as a virtualized function on a suitable platform (e.g., cloud infrastructure).

The AMF or AMF entity 340 provides UE-based authentication, authorization, mobility management, etc. For example, the AMFs 340 are access technology independent, and thus the mobile wireless communication device 130 is connected to a single AMF 340. In other words, even a mobile wireless communication device 130 requiring multiple access technologies is connected to only a single AMF 340.

The AMF 340 forms, for example, a network entity having the first network identity 111 and the first network address 112 as described above with reference to fig. 2 and is responsible for terminating or replying to a message or communication request from the first integrated subscriber identity module 150 of the mobile radio communication interface 140 to initiate communication of the first integrated subscriber identity module 150 in the first mobile radio network 110.

The AMF 340 may further process messages or communication requests from the second integrated subscriber identity module 160 of the mobile wireless communication interface 140 and forward these messages or communication requests to the second mobile wireless network 120, for example, by the mechanism described below with reference to fig. 4, to initiate communication of the second integrated subscriber identity module in the second mobile wireless network 120.

The SMF or SMF entity 341 is responsible for session management and assigns one or more IP addresses to the mobile wireless communication device 130. The SMF 341 also selects the UPF332 and controls the UPF332 in terms of data transfer (e.g., with respect to transferring the first data 114). When the mobile wireless communication device 130 has multiple sessions, a respective SMF 341 may be associated with each session to control it individually and possibly provide multiple functions in each session.

AF or AF entity 343 provides information about packet traffic and provides this information to PCF 342, which is responsible for policy control to guarantee quality of service (QoS). Based on this information, PCF 342 determines mobility and session management criteria for AMF 340 and SMF 341 to function properly.

The AUSF or AUSF entity 351 stores data for authenticating the mobile wireless communications device 130, while the UDM 352 stores subscription data or subscriber data for the mobile wireless communications device 130. The data network DN 333 is not part of the NG core network and provides internet access and operator services.

The presentation of reference points of the architecture can be used to represent refined message flows in the Next Generation (NG) standardization. Reference point N1 301 is defined as transmission signaling between mobile wireless communication device 130 and AMF 340. The reference points connecting AN 331 with AMF 340 and connecting AN 331 with UPF332 are defined as N2302 and N3 303, respectively. There is no reference point between AN 331 and SMF 341, but there is a reference point N11 between AMF 340 and SMF 341. This means that SMF 341 is controlled by AMF 340. The N4 304 is used by the SMF 341 and the UPF332 so that the UPF332 can be set using control signals generated by the SMF 341 and the UPF332 can report its status to the SMF 341. N9 309 is a reference point connecting between different UPFs 332 and correspondingly N14 314 is a reference point between different AMFs 340. N15 315 and N7 307 are defined so that PCF 342 may apply its criteria to AMF 340 or SMF 341.AMF 340 requires N12 312 to perform authentication of mobile wireless communication device 130. The reason for defining N8 308 and N10 310 is that AMF 340 and SMF 341 require subscription data for mobile wireless communication device 130.

Next generation networks aim to achieve a separation of the user plane and the control or control plane. The user plane transmits user data traffic and the control plane transmits signaling in the network. In fig. 3, the UPF 332 is located in the user plane, while all other network functions (i.e., AMF 340, SMF 341, PCF 342, AF 343, AUSF351, and UDM 352) are located in the control plane. The separation of the user plane from the control plane ensures independent expansion of resources on each network plane. This separation also allows the UPF 332 to be provided in a distributed manner separate from the functionality of the control plane.

The NG architecture consists of modular functionality. For example, AMF 340 and SMF 341 are independent functions in the control plane. Separate AMFs 340 and SMFs 341 allow independent development and extension. Other control plane functions (such as PCF 342 and AUSF 351) can also be separated. The modular functional design shown in fig. 3 also allows the next generation network to flexibly support various services.

Each network function interacts directly with another NF. In the control plane, a series of interactions between two NFs is defined as a service, so that it is possible to reuse the service. The service allows support for modularity. The user plane supports interactions such as forwarding operations between different UPFs 332.

The next generation network supports roaming, i.e. mobile radio network subscribers are able to automatically answer or dial calls, send and receive data or access other mobile radio network services in a mobile radio network other than their home network. There are two types of application scenarios, one is local routing (HR) and the other is local grooming (LBO).

Fig. 4 shows a schematic diagram of a mobile wireless communication device 130 according to the present 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 mobile wireless network 110 according to fig. 1 and 2 and a second network slice 410 corresponding to the second mobile wireless network 120 according to fig. 1 and 2. The two network slices 440, 410 have the same structure as generally described above with reference to fig. 3, but not all network elements are shown in detail for clarity. In particular, the first network slice 440 comprises an access and mobility management network element 451 having the same functionality and the same interface as the AMF entity 340 described above with reference to fig. 3.

The first network slice 440 may also be a home network slice of the first integrated subscriber identity module 150 and a guest network slice of the second integrated subscriber identity module 160, and the second network slice 410 may be a home network slice of the second integrated subscriber identity module 150 and a guest network slice of the first integrated subscriber identity module 150.

The first network slice 440 is, for example, the first integrated subscriber identity module 150 or a network slice in which the user of the module is registered, i.e. in which the user has contracted with the network operator.

The second network slice 410 is, for example, the second integrated subscriber identity module 160 or a network slice in which the user of the module 160 is registered, i.e. in which the user has contracted with the network operator. A user here generally refers to the same user that has obtained two subscriber identity modules.

The first network slice 440 further comprises a session management network element 452 having the same functionality and the same interfaces as the SMF entity 341 described above with reference to fig. 3. The first network slice 440 further comprises a database 460, the network element authentication server 461, the data manager 462 and the policy controller 463 in the database 460 having the same functions and the same interfaces as the network elements AUSF 351, UDM 352 and PCF 342 described above with reference to fig. 3.

The same network element with the same functions and interfaces is also contained in the second network slice 410, namely an access and mobility management network element 421, a session management network element 422 and a database 430 with a network element authentication server 431, a data manager 432 and a policy controller 433.

A network access entity 451 for allowing a communication connection to be established is arranged in the first network slice 440. The mobile wireless communication device 130 is connected to the network access entity 451 via an N1 interface (also commonly referred to herein as a specific or dedicated interface of the communication device 130). The network access entity 451 is connected to the respective network elements of the second network slice 410 and the first network slice 440 via the various communication interfaces as described above with reference to fig. 3. The network access entity 451 is connected to the communication device 130 via an N1 interface. The network access entity 451 is connected via an A1 interface (also called a specific or dedicated interface) to the network access entity 421 of the second network slice 410.

As described above with reference to fig. 1 and 2, the network identification is received via the N1 interface, which may be the first network identification 111 from the first network slice 440 or the second network identification 121 from the second network slice 410. Here, the second network identification 121 from the second network slice 410 may be transmitted to the first network slice 440 via the A1 interface 406 and further to the mobile wireless communication device 130 via the N1 interface.

Furthermore, the network access entity 451 of the first network slice 440 provides all necessary data for network access to the communication interface 140 of the mobile wireless communication device 130 via the N1 interface. The network access entity 451 may query the database 460 of the first network slice 440 for network capabilities of the first network slice 440, e.g. via the N8, N12, N15, N22 interfaces according to the system architecture described in fig. 3, and it may also query the second network slice 410 of the mobile wireless communication device 130 via the A1 interface 406 for subscriber data 406 of the mobile wireless communication device 130 through the network access entity 421.

The network access entity 451 of the first network slice 440 may also query the subscriber data, the network address of the second network slice 410, and the network identification 121 of the second network slice 410 from the network access entity 421 of the second network slice 410 via the A1 interface 406 and available to the communication interface 140 of the mobile wireless communication device 130. Of course, the network access entity 451 may also direct these queries to the database 430 of the second network slice 410 and receive the relevant information directly, i.e. without bypassing the network access entity 421.

After receiving the network identification from the first network slice 440 or the second network slice 410 via the N1 interface, the communication interface 140 of the mobile wireless communication device 130 may compare the received network identification with the permanently stored first network identification 111 and/or second network identification 121.

When the received network identification matches the first network identification 111, the mobile wireless communication interface 140 may read the first data 114 from the first data store 180 and send the first data 114 to the first network slice 440 along with the first mobile wireless subscriber identifier 113. This sends the first data 114 to the first network slice 440, i.e. to the network slice 440 associated with the first subscriber identity module 150.

Similarly, when the received network identification matches the second network identification 121, the mobile wireless communication interface 140 may read the second data 124 from the second data store 190 and send the second data 124 to the second network slice 410 along with the second mobile wireless subscriber identifier 123. This sends the second data 124 to the second network slice 410, i.e. to the network slice 410 associated with the second subscriber identity module 160.

In particular, the method for establishing a communication connection with the first integrated subscriber identity module 150 via the network access entity 451 may proceed as follows: in a first step, a registration request is transmitted from the first integrated subscriber identity module 150 to the network access entity 451 of the first network slice 440. The registration request includes a first mobile wireless subscriber identifier of the first integrated subscriber identity module 150. The registration request is transmitted to the network access entity 451 via a specific or dedicated communication interface, i.e. the N1 interface.

Then, in a further step, the network access entity 451 queries the database 460 of the first network slice 440 or from an external database for subscriber specific registration data of the first integrated subscriber identity module 150 based on the first mobile radio subscriber identifier of the first integrated subscriber identity module 150.

The network identification of the first network slice 440 is then transmitted from the AMF entity 451 of the first network slice 440 to the communication interface 140 of the mobile wireless communication device 130 via the N1 interface.

The network access entity 451 may then transmit network access data for accessing the first integrated subscriber identity module 150 to the first network slice 440, either together with the network identity of the first network slice 440 or chronologically via the particular communication interface N1 and the communication interface 140 of the mobile wireless communication device 130, to the first integrated subscriber identity module 150. The network access data for the first integrated subscriber identity module 150 to access the first network slice 440 is, for example, based on subscriber specific registration data of the first integrated subscriber identity module 150, such as the first mobile wireless subscriber identifier of the first integrated subscriber identity module 150, or other registration data of the first integrated subscriber identity module 150, such as name, password, network key, etc. Here, the network access data indicates the capabilities of the first network slice 440, particularly those available to the first integrated subscriber identity module 150.

Finally, the first integrated subscriber identity module 150 establishes a communication connection with a corresponding network element of the first network slice 440 based on the network identification of the first network slice 440 and the network access data to the first network slice 440.

The network access data may, for example, indicate the following capabilities of the first network slice 440: the first network slice 440 may allocate or the number and types of additional network slices with which the first network slice may establish a communication connection, support specific network slice functions, the ability to transmit data and/or voice, support 2G/3G/4G and/or 5G roaming, and specific services supported by the first network slice 440.

The registration request may also include an identification of the particular service from which the first integrated subscriber identity module 150 makes a request to the first network slice 440. When the first network slice 440 supports a particular service, the particular service may be provided by the first network slice 440 based on an identification of the particular service. Otherwise, when it does not support a particular service, the network access entity 451 may transmit a network slice ID of another mobile wireless network supporting the particular service to the first integrated subscriber identity module 150. In this case, the network slice ID of the further network slice supporting the particular service to which the first network slice 440 can allocate or with which the first network slice 440 can establish a communication connection may also be transmitted to the first integrated subscriber identity module 150.

Registration request 203 may further include a key for authenticating first integrated subscriber identity module 150. Network access entity 451 may authenticate first integrated subscriber identity module 150 via authentication entity 461 of first network slice 440 based on the key. This process may be completed prior to querying subscriber-specific registration data.

In particular, the method for establishing a communication connection with the second integrated subscriber identity module 160 via the network access entity 451 may proceed as follows: in a first step, a registration request is transmitted from the second integrated subscriber identity module 160 to the network access entity 451 of the first network slice 440, establishing a communication connection in the manner described above for the first integrated subscriber identity module 150. The registration request includes a second mobile wireless subscriber identifier 123 of a second integrated subscriber identity module 160. The registration request is transmitted to the network access entity 451 via a specific communication interface, i.e. the N1 interface.

Then, in a further step, based on the second mobile wireless subscriber identifier 123 of the second integrated subscriber identity module 160, the network access entity 451 queries the subscriber specific registration data of the second integrated subscriber identity module 160 from the database 430 of the second network slice 410 or from an external database via the specific A1 interface 406 through the network access entity 421.

The network identity of the second network slice 410 is then transferred from the AMF entity 421 of the second network slice 410 via the A1 interface 406 to the AMF entity 451 of the first network slice 440 and from there further via the N1 interface to the communication interface 140 of the mobile wireless communication device 130.

The network access data (which is used to access the second integrated subscriber identity module 160 to the second network slice 410) may then be transmitted to the second integrated subscriber identity module 160 together with the network identity of the second network slice 410 or chronologically through the network access entity 421 of the second network slice 410 and the network access entity 451 of the first network slice 440 and to the communication interface 140 of the mobile wireless communication device 130 via the specific communication interface A1 and the specific communication interface N1.

The network access data for the second integrated subscriber identity module 160 to access the second network slice 410 is, for example, subscriber specific registration data based on the second integrated subscriber identity module 160, such as the second mobile wireless subscriber identifier of the second integrated subscriber identity module 160, or other registration data of the second integrated subscriber identity module 160, such as name, password, network key, etc. The network access data indicates the capabilities of the second network slice 410, particularly those available to the second integrated subscriber identity module 160.

Finally, the second integrated subscriber identity module 160 establishes a communication connection with corresponding network elements of the first network slice 440 and the second network slice 410 based on the network identification of the second network slice 410 and the network access data to the second network slice 410.

The network access data may, for example, indicate the following capabilities of the second network slice 410: the second network slice 410 may allocate or the number and type of additional network slices with which the second network slice may establish a communication connection, support specific network slice functions, the ability to transmit data and/or voice, support 2G/3G/4G and/or 5G roaming, and specific services supported by the second network slice 410.

The registration request may also include an identification of the particular service from which the second integrated subscriber identity module 160 makes a request to the second network slice 410. When the second network slice 410 supports a particular service, the particular service may be provided by the second network slice 410 based on an identification of the particular service. Otherwise, when it does not support a particular service, the network access entity 451 may transmit a network slice ID of another mobile wireless network supporting the particular service to the second integrated subscriber identity module 160. In this case, the network slice ID of the further network slice supporting the particular service to which the second network slice 410 may assign or with which the second network slice may establish a communication connection may also be transmitted to the second integrated subscriber identity module 160.

The registration request may further include a key for authenticating the second integrated subscriber identity module 160. The network access entity 451 may authenticate the second integrated subscriber identity module 160 via the authentication entity 431 of the second network slice 410 based on the key. This process may be completed prior to querying subscriber-specific registration data.

Fig. 5 shows a schematic diagram of a method 500 for wireless communication via a first mobile radio network 110 and via a second mobile radio network 120, for example as described above with reference to fig. 1 to 4, the first mobile radio network 110 having a first network identification 111 and the second mobile radio network 120 having a second network identification 121, and for automatically selecting a network via a mobile radio communication interface 140 of a mobile radio communication device 130.

The mobile wireless communication interface 140 has a first integrated subscriber identity module (iksim 1) 150 and a second integrated subscriber identity module (iksim 2) 160. The first integrated subscriber identity module 150 is implemented as an embedded integrated circuit and permanently stores the first mobile wireless subscriber identifier 113 along with the first network identification 111, as described above with reference to fig. 1-4.

The second integrated subscriber identity module 160 is implemented as an embedded integrated circuit and permanently stores the second mobile wireless subscriber identifier 123 along with the second network identification 121, as described above with reference to fig. 1-4.

As described above with reference to fig. 1-4, the first mobile wireless subscriber identifier 113 identifies the first integrated subscriber identity module 150 in the first mobile wireless network 110 and the second mobile wireless subscriber identifier 123 identifies the second integrated subscriber identity module 160 in the second mobile wireless network 120.

The mobile wireless communication device 130 has a first data store 180 configured to store first data 114 for forwarding to a first mobile wireless network and a second data store 190 configured to store second data 124 for forwarding to a second mobile wireless network, as described above with reference to fig. 1-4.

The method 500 includes the steps of:

receiving 501, by the mobile wireless communication interface 140, a network identification;

comparing 502 the received network identity with at least one of the permanently stored first network identity 111 and second network identity 121;

reading 503 first data 114 from the first data storage 180 and transmitting the first data to the first mobile radio network 110 together with the first mobile radio subscriber identifier 113 when the received network identification corresponds to the first network identification 111;

when the received network identification corresponds to the second network identification 121, second data 124 is read 504 from the second data storage 190 and sent to the second mobile radio network 120 together with the second mobile radio subscriber identifier 123.
