Description

Communication system for cooperative communication with mobile wireless communication devices

Technical Field

The invention relates to a communication system for mobile wireless cooperative communication via a mobile wireless network with a network identification, comprising two mobile wireless communication devices, each having an integrated subscriber identity module. The invention also relates to a corresponding mobile radio communication device and to a method for cooperative communication via a mobile radio network.

Background

Mobile wireless communication devices with one or more SIM cards are increasingly used in the field of IoT (Internet of Things) to network machines. Such devices not only network machines, but also typically network physical and virtual objects to each other and allow them to cooperate with each other through communications. The functionality implemented using the "internet of things" technology allows human interaction with any electronic system networked through it, as well as with the system itself. The goal of the internet of things is to automatically collect relevant information from the real world, correlate that information, and make it available to the network. For this purpose, for example, with reference to the 3gpp ts 23.501 standard overview, communication networks according to the 5G system architecture are increasingly being used.

In the field of industrial automation and the field of communication of the internet of things, failover is becoming a basic requirement. In critical control, the power supply is of a redundant design, ensuring operation even in the event of a power supply failure. In IoT communications, in addition to power feeding, data transmission via a communication interface may also be subject to failure, e.g., wireless signals are shielded. Especially in the field of factory automation and automatic control systems such as autonomous vehicles, secure communication is required to avoid harm as much as possible in advance.

Disclosure of Invention

The object of the invention is to propose a concept for mobile radio communication that is fail-over and highly available, which ensures communication with a low failure rate and high availability in human, human-machine and/or machine-machine communication.

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

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

The mobile wireless communication devices and mobile wireless networks described herein may include various technologies and network standards, for example, in compliance with a 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 subnets. Here, a network slice is a form of virtual network architecture, wherein the network architecture is divided into virtual elements that can be linked (also by software) to each other. 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 scenario.

Each of these virtual networks or network slices provides the resources and network topology for a particular service and traffic using a corresponding network segment. This allows functions such as speed, capacity, connectivity, and coverage to be assigned to meet the specific requirements of each application scenario, but functional components can also be shared among various network slices. To this end, each network slice can obtain 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.

For example, 5G supports three different service classes, enhanced Mobile broadband (eMBB), Mass machine class communication (mMTC, also known as IoT, the Internet of things), and ultra-reliable and low latency communication (UR-LL C).

The mobile wireless communications devices described below include a mobile wireless communications interface, or simply a communications interface, that performs a number of 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 present invention relates to a communication system for cooperative communication via a mobile radio network, wherein the mobile radio network has a network identification, the communication system comprising: a first mobile wireless communications device having the following features: a first mobile wireless communication interface for communicating with a mobile wireless network, wherein the first mobile wireless communication interface has a first Integrated Subscriber Identity Module (iSIM), wherein the first Integrated Subscriber Identity Module is implemented as an embedded Integrated circuit and permanently stores a first mobile wireless Subscriber identifier, a network identification, and a network address of the mobile wireless network, wherein the first mobile wireless Subscriber identifier identifies the first Integrated Subscriber Identity Module in the mobile wireless network; a first data store configured to store first data for transmission to a mobile wireless network; a first bus communication interface; a second mobile wireless communications device having the following features: a second mobile wireless communication interface for communicating with a mobile wireless network, wherein the second mobile wireless communication interface has a second integrated subscriber identity module, wherein the second integrated subscriber identity module is implemented as an embedded integrated circuit and permanently stores a second mobile wireless subscriber identifier, a network identification, and a network address of the mobile wireless network, wherein the second mobile wireless subscriber identifier identifies the second integrated subscriber identity module in the mobile wireless network; a second data store configured to store first data for transmission to a mobile wireless network; a second bus communication interface, wherein the second bus communication interface is connected to the first bus communication interface via a data bus; wherein the second mobile wireless communication interface is configured to: receiving a network signal from the mobile wireless communications network and comparing a signal strength of the received network signal to a threshold, wherein the second mobile wireless communications interface is further configured to: reading the network identification, the network address of the mobile radio network and the second mobile radio subscriber identifier from the second integrated subscriber identity module and sending the second mobile radio subscriber identifier together with the network identification, the network address of the mobile radio network and the second data to the network address of the mobile radio network when the received network signal meets or exceeds the threshold; and when the received network signal is below a threshold, passing the network address of the mobile wireless network to the second bus communication interface along with the network identification, the second data and the second mobile wireless subscriber identifier; wherein the second bus communication interface is configured to transmit the received network address of the mobile radio network together with the network identification, the second data and the second mobile radio subscriber identifier via the data bus to the first bus communication interface of the first mobile radio communication device; wherein the first mobile radio communication interface is configured to send the received second data to the network address of the mobile radio network together with the second mobile radio subscriber identifier and the network identification.

Such mobile radio communication systems ensure particularly secure and highly usable communication due to the cooperative data transmission of the two mobile radio communication devices. If the wireless signal of the second communication device is poorly received, for example because the second communication device is in a shielded position, the data can be transmitted via the bus communication interface to the first mobile wireless communication device and thus to the mobile wireless network via the mobile wireless communication interface of the first mobile wireless communication device. The same applies to the opposite direction and to designs with more than two mobile wireless communication devices. In the case of a plurality of mobile radio communication devices, the data can be forwarded, for example via the respective bus communication interface, to the communication device which receives the best network signal and transmitted thereby to the mobile radio network. This allows for a very high availability of data transmission to the mobile radio network. A fail-over type mobile radio communication of a communication system can be realized, and a low failure rate and high availability are ensured at the time of communication among human beings, human-machines and/or machines due to cooperative communication of mobile radio communication devices. In particular, as described in the present disclosure, the mobile wireless communication system ensures failover and highly available mobile wireless communication via mobile wireless networks and network technologies, particularly via network slices of a 5G system architecture.

The data of the respective mobile radio communication device is identified by the respective subscriber identifier of the mobile radio communication device, so that it can be associated with the respective mobile radio subscriber at any time in the mobile radio network. The subscriber identifier is a unique identifier in the Mobile radio network, such as an IMSI (International Mobile subscriber identity).

In an exemplary embodiment of the mobile radio communication system, the data bus may connect the second bus communication interface to the first bus communication interface bypassing the mobile radio network.

The communication path between the two communication devices may be, for example, a sidelink communication path that enables a direct mobile wireless communication connection between the two communication devices, such as one that conforms to the mobile wireless standard 5G NR V2X (5G New radio Vehicle-to-analysis, 5G New Wireless Vehicle-to-the-outside interaction), as AN alternative to a mobile wireless connection, a W L AN connection or a Bluetooth connection may also be implemented as a bus communication interface.

In an exemplary embodiment of the mobile radio communications system, the second bus communication interface is configured to: the master signal is received from the first bus communication interface and, in response to receiving the master signal, the second mobile radio communication interface is instructed to discontinue sending the network identification and the network address of the mobile radio network to the network address of the mobile radio network together with the second data and the second mobile radio subscriber identifier, and to send the network identification and the network address of the mobile radio network together with the second data and the second mobile radio subscriber identifier to the first bus communication interface of the first mobile radio communication device via the data bus.

This achieves the advantage that one of the two mobile radio communication devices can be configured as a master communication device, by means of which mobile radio communication with the network will be carried out. The primary communication device may, for example, be equipped with very high resources for mobile wireless communication, or it may be set up in a location where the wireless channel to the mobile wireless network is excellent, such as on the roof of a house, while other mobile wireless communication devices may be set up in other locations where wireless reception is poor. The data can then be transmitted to the primary communication device via the bus interface, for example from the basement to the rooftop via the power line of the house. Other mobile wireless communication devices may then be set up, for example, in basements with a lot of measurement data. Alternatively, the other mobile radio communication devices may be set up in a secure area in which security-related data can be detected, which data can be transmitted to the master communication device via the bus communication interface.

In an exemplary embodiment of the mobile radio communications system, the first mobile radio communications interface is configured to: when the received second data is sent to the network address of the mobile radio network together with the second mobile radio subscriber identifier and the network identification, the first mobile radio subscriber identifier is additionally added.

This achieves the advantage that the mobile radio network knows, on the basis of the received data, both from which device the data came from and by which device the data was transmitted. The mobile radio network is aware that the wireless accessibility of the second mobile radio communication device via the mobile radio communication interface is or has been compromised, so that it can initiate appropriate service measures, such as changing the radio resource, for example by transmitting on another radio channel, or notifying a service technician to perform a service on the second mobile radio communication device.

In an exemplary embodiment of the mobile radio communications system, the first mobile radio communications interface is configured to: transmitting first data to a network address of the mobile radio network together with a first mobile radio subscriber identifier and a network identification during a first time interval; and the first mobile wireless communications interface is configured to: the received second data is transmitted to the network address of the mobile radio network together with the second mobile radio subscriber identifier and the network identification within a second time interval, wherein the first time interval and the second time interval are different from each other.

This achieves the advantage that the two communication devices transmit their data to the mobile radio network at different time intervals. This allows for efficient use of the wireless interface of the mobile wireless network and two or more communication devices do not become overloaded with their data since the transmissions do not occur simultaneously. Furthermore, the design of the communication system can be planned better and the system can be operated in a resource efficient manner.

In an exemplary embodiment of the mobile radio communications system, the second bus communication interface is configured to: the network identification and the received network address of the mobile radio network are transmitted together with the second data and the second mobile radio subscriber identifier to a first bus communication interface of the first mobile radio communication device via a data bus within a first time interval.

This achieves the advantage that both interfaces, i.e. the mobile radio communication interface and the bus communication interface, can be used together and are therefore particularly efficient. During the transmission of data of the first mobile radio communication device to the mobile radio network by the mobile radio communication interface within the first time interval, data of the second mobile radio communication device is transmitted simultaneously (i.e. within the first time interval) to the first mobile radio communication device via the bus communication interface. This makes particularly efficient use of both interfaces possible.

In an exemplary embodiment of the mobile radio communications system, the second mobile radio communications interface is configured to: sending a registration request to register the second mobile wireless communication device in the mobile wireless network to a network address of the mobile wireless network when the received network signal reaches a threshold; and the second mobile wireless communication interface is configured to: transmitting a registration request to register the second mobile wireless communication device in the mobile wireless network to the network address of the mobile wireless network via the second bus communication interface, the first bus communication interface, and the first mobile wireless communication interface when the received network signal is below the threshold; and the first mobile wireless communications interface is configured to: an acknowledgement from the mobile radio network of a registration request to register the second mobile radio communication device in the mobile radio network is passed to a second bus communication interface of the second mobile radio communication device via the first bus communication interface.

This achieves the advantage that the second mobile radio communication device can automatically register in the network via its mobile radio communication interface when the connection to the network is good, and can register in the network via the first mobile radio communication device when the connection to the network is poor, in which case the acknowledgement of the registration request is forwarded from the first mobile radio communication device to the second mobile radio communication device via the bus communication interface.

In an exemplary embodiment of the mobile radio communication system, the mobile radio communication system comprises a further mobile radio communication device which is constructed analogously to the second mobile radio communication device, but which does not have an own mobile radio communication interface to the mobile radio network, but communicates with the mobile radio network via a bus communication interface to the first mobile radio communication device or the second mobile radio communication device and via their mobile radio communication interface to the mobile radio network.

This has the advantage that the additional mobile radio communication device can be of a particularly cost-effective design, since it does not require its own mobile radio communication interface and does not require any protocol for communication with the mobile radio network via this interface, instead a simple communication protocol via a bus communication interface (such as USB or power line or bluetooth or W L AN) is sufficient, so that a low-cost mobile radio communication device can be designed in the IoT domain, for example, a large number of different sensor data can be collected and its measurements transmitted to the mobile radio network via a master mobile radio communication device specifically designed for this purpose.

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

This provides the technical advantage of being able to employ two integrated subscriber identity modules or iSIM modules in a 5G communication network (especially a network slice) and transmit its data to the mobile radio network with higher availability and lower error susceptibility based on the cooperation of the two communication devices. This allows the advantages of a 5G system architecture to be exploited, i.e. a virtual network architecture on a common physical infrastructure specifically tailored to the requirements of the application, service, device, customer or operator, supporting logical network functions, assigning functions such as speed, capacity, connectivity and network coverage to the application to meet the specific requirements of each application scenario, and sharing functional components across various network slices, etc. Based on the cooperative use of two or more mobile wireless communication devices, failover and availability in a 5G communication network can be significantly improved.

According to a second aspect, the invention relates to a second mobile radio communication device for cooperative communication via a mobile radio network, wherein the mobile radio network has a network identification, wherein the second mobile radio communication device has the following features: a second mobile wireless communication interface for communicating with a mobile wireless network, wherein the second mobile wireless communication interface has a second integrated subscriber identity module, wherein the second integrated subscriber identity module is implemented as an embedded integrated circuit and permanently stores a second mobile wireless subscriber identifier, a network identification, and a network address of the mobile wireless network, wherein the second mobile wireless subscriber identifier identifies the second integrated subscriber identity module in the mobile wireless network; a second data store configured to store second data for transmission to the mobile wireless network; a second bus communication interface, wherein the second bus communication interface is connected to the first bus communication interface of the first mobile wireless communication device via a data bus; wherein the second mobile wireless communication interface is configured to: receiving a network signal from the mobile wireless communications network and comparing a signal strength of the received network signal to a threshold, wherein the second mobile wireless communications interface is further configured to: reading the network identification and the network address of the mobile radio network and the second mobile radio subscriber identifier from the second integrated subscriber identity module and sending the second mobile radio subscriber identifier together with the network identification, the network address of the mobile radio network and the second data to the network address of the mobile radio network when the received network signal reaches or exceeds the threshold; passing the network address of the mobile radio network to the second bus communication interface together with the network identification, the second data and the second mobile radio subscriber identifier when the received network signal is below the threshold; wherein the second bus communication interface is configured to transmit the received network address of the mobile radio network together with the network identification, the second data and the second mobile radio subscriber identifier via the data bus to the first bus communication interface of the first mobile radio communication device.

Such a second mobile radio communication device ensures particularly secure and highly usable communication due to the cooperative data transmission with the first mobile radio communication device. If the wireless signal of the second communication device is poorly received, for example because the second communication device is in a shielded position, data can be transmitted via the bus communication interface to the first mobile wireless communication device and thus via its mobile wireless communication interface to the mobile wireless network. The second mobile wireless communications device can allow for failover mobile wireless communications and ensure low failure rates and high availability when communicating between people, human-machines and/or machines due to cooperative communications with the first mobile wireless communications device. In particular, as described in the present disclosure, the second mobile radio communication system ensures a highly available mobile radio communication via the mobile radio network and the network technology, in particular via the network slice of the 5G system architecture.

In an exemplary embodiment of the second mobile wireless communications device, the second data store is configured to: when above the threshold, deleting the second data after sending the second data to the network address of the mobile radio network; alternatively, when below the threshold, the second data is deleted after being transmitted to the first bus communication interface of the first mobile wireless communication device.

This ensures a particularly efficient recording of data. Once the second data is forwarded to the mobile radio network (in case the radio channel of the second mobile radio communication device is good) or to the first mobile radio communication device (in case the radio channel of the second mobile radio communication device is bad), it can be deleted from the second memory in order to provide room for receiving more data. The second memory always provides space for new second data so that the second mobile radio communication device can record measurement data for a long period of time or even continuously.

According to a third aspect, the invention relates to a method for cooperative communication by a first mobile radio communication device with a second mobile radio communication device via a mobile radio network, wherein the mobile radio network has a network identification, wherein the first mobile radio communication device has the following features: a first mobile wireless communication interface for communicating with a mobile wireless network, wherein the first mobile wireless communication interface has a first integrated subscriber identity module, wherein the first integrated subscriber identity module is implemented as an embedded integrated circuit and permanently stores a first mobile wireless subscriber identifier along with a network identification and a network address of the mobile wireless network, wherein the first mobile wireless subscriber identifier identifies the first integrated subscriber identity module in the mobile wireless network; a first data store configured to store first data for transmission to a mobile wireless network; a first bus communication interface; and wherein the second mobile wireless communications device has the following features: a second mobile wireless communication interface for communicating with a mobile wireless network, wherein the second mobile wireless communication interface has a second integrated subscriber identity module, wherein the second integrated subscriber identity module is implemented as an embedded integrated circuit and permanently stores a second mobile wireless subscriber identifier along with a network identification and a network address of the mobile wireless network, wherein the second mobile wireless subscriber identifier identifies the second integrated subscriber identity module in the mobile wireless network; a second data store configured to store first data for transmission to a mobile wireless network; a second bus communication interface, wherein the second bus communication interface is connected to the first bus communication interface via a data bus; wherein the method comprises the steps of: receiving a network signal from the mobile radio communications network via the second mobile radio communications interface; comparing a signal strength of the received network signal to a threshold; reading a second mobile wireless subscriber identifier, a network identification and a network address of the mobile wireless network from the second integrated subscriber identity module; when the received network signal is above a threshold: sending the second mobile radio subscriber identifier to the network address of the mobile radio network together with the network identification, the network address of the mobile radio network and the second data; when the received network signal is below a threshold: passing the network identification and the network address of the mobile radio network to the second bus communication interface together with the second data and the second mobile radio subscriber identifier; transmitting the received network identification and the network address of the mobile radio network together with the second data and the second mobile radio subscriber identifier via a data bus to a first bus communication interface of the first mobile radio communication device via a second bus communication interface; and transmitting the received second data together with the second mobile radio subscriber identifier and the network identification to the network address of the mobile radio network via the first mobile radio communication interface.

Such an approach ensures particularly secure and highly available communication due to the cooperative data transfer of the two mobile wireless communication devices. If the wireless signal of the second communication device is poorly received, for example because the second communication device is in a shielded position, data can be transmitted via the bus communication interface to the first mobile wireless communication device and thus via its mobile wireless communication interface to the mobile wireless network. The same applies to the opposite direction and to designs with more than two mobile wireless communication devices. In the case of a plurality of mobile radio communication devices, the data can be forwarded, for example via the respective bus communication interface, to the communication device which receives the best network signal and transmitted thereby to the mobile radio network. This allows for a very high availability of data transmission to the mobile radio network. The method allows for failover mobile wireless communications and ensures low failure rates and high availability when communicating between people, human-machines and/or machine-machines due to cooperative communication of the mobile wireless communication devices. In particular, as described in the present disclosure, the method will ensure failover and highly available mobile wireless communications via mobile wireless networks and network technologies, especially via network slices of a 5G system architecture.

Fig. 1 shows a block diagram of a communication system 100 including two mobile

wireless communication devices

131, 132 for cooperative communication via a mobile wireless network 110, according to an example embodiment. Mobile radio network 110 has a network identification 111 that uniquely identifies mobile radio network 110.

The mobile wireless network 110 is identified by its network identification (ID1)111 and is addressable via its network address 112. For example, a network access entity exists in the mobile wireless network 110 that coordinates access to the mobile wireless network 110. The mobile wireless network 110 may then be addressed or accessed via the network address of the network access entity. Which recognizes the network identification 111 of the mobile radio network 110 and can manage access to the mobile radio network 110.

The Network Access entity of the mobile wireless Network 110 may be, for example, a RAN (Radio Access Network) entity, such as a base station or a Radio Access entity in a 5G Network or an AMF (Access and mobility management Function) entity.

The first mobile radio communication device 131 has a first mobile radio communication interface 141 for communicating with the mobile radio network 110. The first mobile radio communication interface 141 comprises a first integrated subscriber identity module (iSIM1)151 implemented as an embedded integrated circuit and permanently storing a first mobile radio subscriber identity 113, a network identity 111 and a network address 112 of the mobile radio network 110. The first mobile wireless subscriber identifier 113 identifies the first integrated subscriber identity module 151 in the mobile wireless network 110.

The second mobile radio communication interface 142 comprises a second integrated subscriber identity module (iSIM2)152 implemented as an embedded integrated circuit and permanently storing a second mobile radio subscriber identity 123, a network identity 111 and a network address 112 of the mobile radio network 110. The second mobile wireless subscriber identifier 123 identifies a second integrated subscriber identity module 152 in the mobile wireless network 110.

The second mobile wireless communication device 132 has a second data store 182 configured to store second data 124 for transmission to the mobile wireless network 110.

The second mobile wireless communications device 132 further has a second bus communications interface 172 that is connected to the first bus communications interface 171 via a data bus 173.

Persistent storage represents: even if the power supply is switched off, the first mobile wireless subscriber identifier 113 is stored in the first integrated subscriber identity module 151 together with the network identification 111 and the network address 112 of the mobile wireless network 110. The same applies to the data being permanently stored in the second integrated subscriber identity module 152.

The first Mobile radio Subscriber identifier 113 is, for example, an identifier of a first Subscriber in the Mobile radio network 110, such as an IMSI (International Mobile Subscriber Identity), i.e. a number for uniquely identifying a network Subscriber in the Mobile radio network 110. The first mobile wireless subscriber identifier 113 may include parameters for identifying and authenticating a first subscriber of the first mobile wireless communication device 131 in the mobile wireless network 110. The same applies to the second mobile wireless subscriber identifier 123 and the second subscriber of the second mobile wireless communication device 132.

The second mobile wireless communication interface 142 is configured to receive the network signal 115 from the mobile wireless communication network 110 and compare the signal strength of the received network signal 115 to the threshold 116. The mobile wireless communication interface 142 is configured to read the network identification 111, the network address 112 of the mobile wireless network 110 and the second mobile wireless subscriber identifier 123 from the second integrated subscriber identity module 152.

When the signal strength of the received network signal 115 is above the threshold value 116, the network identification 111, the network address 112 of the mobile radio network 110 and the second mobile radio subscriber identifier 123 are transmitted to the network address 112 of the mobile radio network 110 together with the second data 124 via the second mobile radio communication interface 142.

When the signal strength of the received network signal 115 is below the threshold 116, the network address 112 of the mobile radio network 110 is passed to the second bus communication interface 172 via the second mobile radio communication interface 142 together with the network identification 111, the second data 124 and the second mobile radio subscriber identifier 123.

The second bus communication interface 172 is configured to transmit the received network address 112 of the mobile wireless network 110 along with the network identification 111, the second data 124, and the second mobile wireless subscriber identifier 123 to the first bus communication interface 171 of the first mobile wireless communication device 131 via the data bus 173.

The first mobile radio communication interface 141 is configured to send the received second data 124 to the network address 112 of the mobile radio network 110 together with the second mobile radio subscriber identifier 123 and the network identification 111.

Such a mobile radio communication system 100 ensures particularly secure and highly usable communication due to the cooperative data transmission of the two mobile

radio communication devices

131, 132. If the wireless signal 115 of the second communication device 132 is poorly received, for example because the second communication device 132 is in a shielded position, the second data 124 can be transmitted to the first mobile wireless communication device 131 via the second bus communication interface 172 and thus to the mobile wireless network 110 via the mobile wireless communication interface 141 of the first mobile wireless communication device 131. The same applies to the opposite direction and designs having more than two mobile

wireless communication devices

131, 132.

In the case of a plurality of mobile radio communication devices, the data can be forwarded, for example via the respective bus communication interface, to the communication device receiving the best network signal and transmitted thereby to the mobile radio network 110. This allows for a very high availability of data transmission to the mobile radio network 110. Thereby realizing the fail-over mobile wireless communication of the mobile wireless communication system 100 and ensuring a low failure rate and high availability at the time of communication among human beings, human-machines and/or machine-machines due to cooperative communication of the mobile

wireless communication devices

131, 132. In particular, the mobile radio communication system 100 ensures a highly available mobile radio communication with failover via mobile radio networks and network technologies, especially via network slices of the 5G system architecture, as detailed in fig. 4.

The communication system 100 is shown only by way of example in this figure and may also include additional mobile wireless networks that may be configured similarly to the network 110 shown in this figure, in addition, or instead of the mobile wireless network 110, networks having other radio access technologies may be implemented, such as a W L AN or WiFi network.

In addition to the first and second integrated

subscriber identity modules

151, 152 shown in fig. 1, the mobile

wireless communication devices

131, 132 may each include further subscriber identity modules, e.g., isims for accessing other mobile wireless networks, e.g., based on other network access technologies.

Here, the second data 124 may be associated with a second subscriber identity module 152. For example, the second data 124 may be data that may no longer be stored in the second subscriber identity module 152 and thus transferred to the second data storage 182. Such data may for example relate to measured values, such as recorded image or voice data, measured by the second subscriber identity module 152, or temperature values, pressure values, level values, current strengths, voltage values, etc. The same applies to the first data 114 of the first subscriber identity module 151.

The first mobile radio communication device 131 and the second mobile radio communication device 132 can each comprise an actuator or an interface for an actuator, which is configured to derive or read out a control command for actuating the actuator from the first data 114 or the second data 124 in the first data memory 181 or the second data memory 182 and to forward the control command to the actuator or the interface for the actuator in order to actuate the actuator accordingly.

The actuator may be, for example, a machine component that may be controlled by the first data 114 or the second data 124. The actuator can be, for example, an automated or home-only household appliance that can be controlled via the first data 114 or the second data 124 in a house or a residence. Alternatively or additionally, the actuator may be, for example, a speaker or a vibration device of the first mobile wireless communication device 131 or the second mobile wireless communication device 132 that can be actuated and activated via the first data 114 or the second data.

The mobile wireless network 110 may be, for example, a subnet or slice of a 5G mobile wireless network, as detailed, for example, with reference to fig. 4.

The first mobile wireless communication device 131 and the second mobile wireless communication device 132 may each include a sensor configured to detect a value of a physical quantity and store the value as the first data 114 or the second data 124 in the first data memory 181 or the second data memory 182. The physical quantity may be, for example, a temperature value, a pressure value, a level value, a current intensity, a voltage value, etc.

The data bus 173 may connect the second bus communication interface 172 to the first bus communication interface 171 around the mobile wireless network 110.

This achieves the advantage that the two mobile

radio communication devices

131, 132 are directly connected via the two bus communication interfaces 171, 172 without first establishing communication via the mobile radio network 110. This ensures high availability because the communication path between the two

communication devices

131, 132 is necessarily bridged over a shorter distance than the path for communication via the uplink and downlink of the mobile radio network. The communication path between the two

communication devices

131, 132 may thus be, for example, a sidelink communication path, which enables a direct mobile Radio communication connection between the two

communication devices

131, 132, for example, in accordance with the mobile Radio standard 5G NR V2X (5G New Radio Vehicle-to-authentication, 5G New Radio Vehicle-to-outside interaction).

The use of wired connections may be beneficial in situations where the

communication devices

131, 132 are IoT devices, such as IoT sensors or IoT actuators that are not remote from each other in a home network or factory, and transmit different data, such as temperature, pressure, switch positions, orientation of machine components, control signals, etc.

Fig. 1 also shows a second mobile radio communication device 132 for cooperative communication via the mobile radio network 110, wherein the mobile radio network 110 has a network identification 111.

The second mobile radio communication device 132 comprises a second mobile radio communication interface 142 for communicating with the mobile radio network 110, wherein the second mobile radio communication interface 142 comprises a second Integrated Subscriber Identity Module (iSIM) 152, wherein the second Integrated Subscriber Identity Module 152 is implemented as an embedded Integrated circuit and permanently stores the second mobile radio Subscriber identifier 123, the network identification 111 and the network address 112 of the mobile radio network 110, wherein the second mobile radio Subscriber identifier 123 identifies the second Integrated Subscriber Identity Module 152 in the mobile radio network 110.

The second mobile wireless communication device 132 includes a second data store 182 configured to store second data 114 for transmission to the mobile wireless network 110.

The second mobile wireless communications device 132 includes a second bus communications interface 172 that is connected to the first bus communications interface 171 of the first mobile wireless communications device 131 via a data bus 173.

The second mobile wireless communication interface 142 is configured to receive the network signal 115 from the mobile wireless communication network 110 and compare the signal strength of the received network signal 115 to the threshold 116.

The second mobile wireless communication interface 142 is further configured to: when the signal strength of the received network signal 115 is above the threshold 116, the network identification 111 and the network address 112 of the mobile radio network 110 and the second mobile radio subscriber identifier 123 are read from the second integrated subscriber identity module 152 and the second mobile radio subscriber identifier 123 is sent to the network address 112 of the mobile radio network 110 together with the network identification 111, the network address 112 of the mobile radio network 110 and the second data 124.

The second mobile wireless communication interface 142 is further configured to: when the signal strength of the received network signal 115 is below the threshold 116, the network address 112 of the mobile wireless network 110 is passed to the second bus communication interface 172 together with the network identification 111, the second data 124 and the second mobile wireless subscriber identifier 123.

The second data store 182 may be configured to: above the threshold 116, deleting the second data 124 after sending the second data 124 to the network address 112 of the mobile wireless network 110; or when below the threshold 116, the second data 124 is deleted after the second data 124 is sent to the first bus communication interface 171 of the first mobile wireless communication device 131.

This ensures a particularly efficient recording of data. Once the second data 124 is forwarded to the mobile wireless network 110 (in the case of a good wireless channel of the second mobile wireless communication device 132) or to the first mobile wireless communication device 131 (in the case of a bad wireless channel of the second mobile wireless communication device 132), it can be deleted from the second memory 182 to provide room for receiving additional second data. The second memory 182 always provides space for new second data 124 so that the second mobile wireless communications device 132 can record measurement data for a long period of time, or even continuously.

Fig. 2 shows a block diagram of a communication system 200 for cooperative communication in which two mobile

wireless communication devices

131, 132 transmit data at

different time intervals

201, 202, according to an example embodiment.

The communication system 200 may be constructed in accordance with the communication system 100 described in fig. 1.

In the communication system 200, the second bus communication interface 172 of the second mobile wireless communication device 132 is configured to: receives the master signal from the first bus communication interface 171 and, in response to receiving the master signal, instructs the second mobile radio communication interface 142 to discontinue sending the network identification 111 and the network address 112 of the mobile radio network 110 to the network address 112 of the mobile radio network 110 together with the second data 124 and the second mobile radio subscriber identifier 123 and to send only the network identification 111 and the network address 112 of the mobile radio network 110 together with the second data 124 and the second mobile radio subscriber identifier 123 to the first bus communication interface 171 of the first mobile radio communication device 131 via the data bus 173.

This achieves the advantage that one of the two mobile wireless communication devices, here for example the first mobile wireless communication device 131 in fig. 2, can be configured as a master communication device, through which mobile wireless communication with the network 110 is accomplished.

The primary communication device 131 may, for example, be equipped with extremely high resources for mobile wireless communications, or it may be set up in a location where the wireless channel to the mobile wireless network 110 is excellent, such as on the roof of a house, while other mobile wireless communication devices (such as the second mobile wireless communication device 132 in fig. 2) may be set up in other locations where wireless reception is poor. Data may then be transmitted to the primary communication device 131 via the bus interfaces 172, 171, for example from the basement to the rooftop via the power lines of the house. Other mobile wireless communication devices may then be set up, for example, in basements with a lot of measurement data. Alternatively, other mobile wireless communications devices may be set up within a secure area where security related data may be detected, which may be transmitted to the primary communications device 131 via the

bus communications interface

172, 171.

The first mobile wireless communication interface 141 may be further configured to: when the received second data 124 is sent to the network address 112 of the mobile radio network 110 together with the second mobile radio subscriber identifier 123 and the network identification 111, the first mobile radio subscriber identifier 113 is additionally added.

Thus, the mobile radio network 110 can know both from which device the data came from and through which device the data was transmitted based on the received data. Thus, when the mobile wireless network 110 has received data accompanied by the first mobile wireless subscriber identifier 113 and the second mobile wireless subscriber identifier 123, it can be known that a problem is occurring or has occurred with the wireless accessibility of the second mobile wireless communication device 132 via the second mobile wireless communication interface 142. The network 110 can initiate appropriate servicing measures such as changing wireless resources, for example by transmitting over another wireless channel, or notifying a service technician to service at the second mobile wireless communications device 132.

The first mobile wireless communication interface 141 may be configured to: during a first time interval 201, the first data 114 is transmitted to the network address 112 of the mobile radio network 110 together with the first mobile radio subscriber identifier 113 and the network identification 111. The first mobile wireless communication interface 141 may be further configured to: within the second time interval 202, the received second data 124 is sent to the network address 112 of the mobile radio network 110 together with the second mobile radio subscriber identifier 123 and the network identification 111. Here, the first time interval 201 and the second time interval 202 may be different from each other.

Thus, the two

communication devices

131, 132 are able to transmit their data to the mobile radio network 110 at different time intervals. This allows for efficient use of the wireless interface of the mobile wireless network 110 and two or more communication devices do not become overloaded with their data since the transmissions do not occur simultaneously. In addition, the design of communication system 200 is better planned and the system can operate in a resource efficient manner.

The second bus communication interface 172 may be configured to: during the first time interval 201, the network identification 111 and the network address 112 of the mobile wireless network 110 are transmitted together with the second data 124 and the second mobile wireless subscriber identifier 123 via the data bus 173 to the first bus communication interface 171 of the first mobile wireless communication device 131.

These two interfaces (mobile

wireless communication interface

141, 142 and bus communication interface 171, 172) can be used in parallel and are therefore particularly efficient. During the transmission of the first data 114 of the first mobile radio communication device 131 to the mobile radio network 110 by the first mobile radio communication interface 141 of the first communication device 131 within the first time interval 201, the second data 124 of the second mobile radio communication device 132 is transmitted simultaneously (i.e. within the first time interval 201) via the bus communication interfaces 172, 171 to the first mobile radio communication device 131. This makes particularly efficient use of both interfaces possible.

Fig. 3 shows a block diagram of a communication system 300 for cooperative communication in which a second mobile wireless communication device 132 can be registered with a mobile wireless network 110 via a first mobile wireless communication device 131, according to an example embodiment.

The communication system 300 may be constructed in accordance with the communication system 100 described in fig. 1 or also in accordance with the communication system 200 described in fig. 2.

The second mobile wireless communication interface 142 is configured to: when the signal quality of the received network signal 115 is above the threshold 116, a registration request 310 to register the second mobile wireless communication device 132 in the mobile wireless network 110 is sent to the network address 112 of the mobile wireless network 110.

The second mobile wireless communication interface 142 is further configured to: when the signal quality of the received network signal 115 falls below the threshold 116, a registration request 310 to register the second mobile wireless communication device 132 in the mobile wireless network 110 is sent to the network address 112 of the mobile wireless network 110 via the second bus communication interface 172, the first bus communication interface 171, and the first mobile wireless communication interface 141.

The first mobile wireless communication interface 141 is configured to: an acknowledgement 311 from the mobile radio network 110 of the registration request 310 for registering the second mobile radio communication device 132 in the mobile radio network 110 is passed via the first bus communication interface 171 to the second bus communication interface 172 of the second mobile radio communication device 132.

In this way, the second mobile radio communication device 132 can automatically register in the network 110 via its mobile radio communication interface 142 when the connection to the network 110 is good, and can register in the network 110 via the first mobile radio communication device 131 when the connection to the network is poor, in which case the acknowledgement B311 of the registration request R310 is forwarded from the first mobile radio communication device 131 to the second mobile radio communication device 132 via the bus communication interfaces 171, 172.

The registration request R310 may, for example, include the second mobile wireless subscriber identifier 123 of the second integrated subscriber identity module 152. The registration request 310 can be transmitted to a network access entity of the mobile wireless network 110 by means of the first mobile wireless communication device 131.

The network access entity may then query subscriber-specific registration data of the second integrated subscriber identity module 152 from a database of the mobile radio network 110 or from an external database based on the second mobile radio subscriber identifier 123 of the second integrated subscriber identity module 152.

The network access data (which is used by the second integrated subscriber identity module 152 to access the mobile wireless network 110) may then be transmitted by the network access entity to the second integrated subscriber identity module 152 and to the second mobile wireless communications device 132 via the first mobile wireless communications interface 141 and the bus communications interfaces 171, 172. The network access data for the second integrated subscriber identity module 152 to access the mobile radio network 110 is for example subscriber specific registration data based on the second integrated subscriber identity module 152, for example the second mobile radio subscriber identifier 123 of the second integrated subscriber identity module 152, or other registration data of the second integrated subscriber identity module 152, for example a name, password, network key, etc.

The network access data indicates the capabilities of the mobile wireless network 110, particularly those available to the second integrated subscriber identity module 152. Finally, based on the network identification 111, the second mobile radio subscriber identifier 123 of the second subscriber identity module 152 and the network access data to the mobile radio network 110, the second integrated subscriber identity module 152 establishes a communication connection with a corresponding network element of the mobile radio network 110.

The network access data may for example indicate the following capabilities of the mobile radio network 110: the number and type of network slices that mobile wireless network 110 can allocate or with which mobile wireless network 110 can establish a communication connection, the ability to support particular network slice functions, transfer data and/or voice, the ability to support 2G/3G/4G and/or 5G roaming, the particular services supported by mobile wireless network 110.

The registration request may also include an identification of the particular service from which the second integrated subscriber identity module 152 made the request to the mobile radio network 110. When mobile wireless network 110 supports a particular service, the particular service may be provided by mobile wireless network 110 based on the identification of the particular service. Otherwise, when it does not support the specific service, the network access entity may transmit the network identification of another mobile wireless network supporting the specific service to the second integrated subscriber identity module 152.

The registration request R310 may further comprise a key for authenticating the second integrated subscriber identity module 152. The network access entity may authenticate the second integrated subscriber identity module 152 via an authentication entity of the mobile wireless network 110 based on the key. This process may be done before querying the subscriber specific registration data.

Fig. 4 shows a schematic diagram of a first mobile wireless communication device 131 and a second mobile wireless communication device 132 for cooperative communication according to the present disclosure in a 5G communication system 400 according to an example embodiment that conforms to the 3GPP TS 23.501 standard. Fig. 4 schematically illustrates the blocks comprised by such a 5G communication system 400.

The first mobile wireless communication device 131 and the second mobile wireless communication device 132 correspond to User Equipment (UE) or a client terminal, respectively, which can be operated by a subscriber to initiate communication in a 5G network, i.e., to start communication (mobile originated, MO) or to accept communication (mobile terminated, MT). The first mobile wireless communications device 131 and the second mobile wireless communications device 132 can also initiate communications without user interaction, for example, the mobile

wireless communications devices

131, 132 can be machine terminals, such as for automobiles, machines, robots, or other devices.

The (R) AN (Radio) Access Network entity 331 represents a (Radio) Access Network used by the first mobile wireless communication device 131 and the second mobile wireless communication device 132 to obtain Access to the 5G communication Network. The interface between each mobile

wireless communication device

131, 132 and the (R) AN can 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.

An AMF (Access and Mobility Management Function) entity 340 represents an Access and Mobility Management Function to manage Access and implement Mobility control. The AMF 340 may also include a network slice selection function. Mobility management is typically not required for wireless access.

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

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

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

A UDM (Unified Data Management) entity 352 provides common Data Management. With this data management, subscriber data and profiles can be saved. This corresponds to the functionality of the HSS in 4G systems, but can be used for mobile and wired access in NGCore networks.

The first communication interface 141 may, for example, transmit the first data 114 to the block UDM352 together with the

network parameters

111, 112, 113 as described above with reference to fig. 1 to 3. This enables, for example, measurements or measurement parameters recorded by the first mobile radio communication device 131 to be stored in the network 400. The same applies to the transmission of the second data 124 by the second mobile wireless communications device 132.

A DN (Data Network) 333 provides a Data Network through which Data is transmitted, for example, from the first mobile wireless communications device 131 to the second mobile wireless communications device 132 or to another mobile wireless communications device or UE. For example, the two

machine terminals

131, 132 as described above with reference to fig. 1 to 3 may communicate with each other via a data network 333.

Thus, the first data 114 may be transmitted from the first mobile wireless communication device 131 to the second mobile wireless communication device 132 or to another mobile wireless communication device or another UE via the DN 333.

An AUSF (Authentication Server Function) entity 351 provides an Authentication Function that a subscriber or first and second mobile

wireless communication devices

131, 132 can use to log onto the network. The first integrated subscriber identity module 151 and the second integrated subscriber identity module 152 may be authenticated, for example, in the 5G network 400 via the block AUSF 351.

The AF (Application Function) entity 351 provides an Application Function with which a specific service, for example, a service set up or used by the first integrated subscriber identity module 151 or the second integrated subscriber identity module 152, can be executed.

An NSSF (Network Slice Selection Function) entity 350 provides a Function of selecting a specific Network Slice. Thus, for example, the first integrated subscriber identity module 151 or the second integrated subscriber identity module 152 may select a first slice or a second slice in the 5G communication system 400 and communicate therewith or transmit

data

114, 124 thereof.

The 5G communication system 400 shown in fig. 4 corresponds to a 5G system architecture conforming to the 3GPP TS 23.501 standard and represents the structure of AN NG (Next Generation) Network consisting of Network Functions (NF) and reference points connected to NF, but in the 3GPP TS 23.501 standard, generally only the UE (User Equipment) designates the terminal device, instead of the specific embodiments shown in fig. 1 to 3 with integrated subscriber identity module iSIM1 or iSIM2, the first and second mobile

wireless communication devices

131 and 132 or the UE are connected to a Radio Access Network (Radio Access Network, RAN)331 or AN Access Network (Access Network, AN)331, the first and second mobile

wireless communication devices

131 and 132 or the UE are also connected to AN Access and RAN function (AMF) 340. 331 represents a Network Access Management Function (AMF) 340. a new RAT (Radio Access Technology )351 and AN Access Network (RAN) 340) or a UE 2, 2) authentication function (SMF) is connected to a mobility and RAN 150, (AMF) 2) a UE) is connected to a mobility and a UE management function (SMF) 340 or a UE) 2 Network management function (aff) 340, a UE) may be selected from the Network functions (RAN) 400, 2) and (SMF 2) a UE) 2, or a UE management function (RAN) originating from which may be selected by a UE, (e.g 2) Network management function (RAN) which may be present in which may be represented by a User Equipment (UE) Network management function (UE) Network Access Network management function (2) and a UE (2) Network management function (RAN) 2, 2) Network management function (RAN) Network management function (r 2) 2.

The Network Function (NF) represents the processing function that the 3GPP takes over in the next generation (NextGen or NG). It has both a functional behavior and acts as an interface. The NF can be implemented as a network element on dedicated hardware, run as a software instance on dedicated hardware, or be implemented as a virtualization 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 AMF 340 is independent of access technology, so the mobile wireless communication device 130 connects to a single AMF 340. In other words, even a first mobile wireless communications device 131 or a second mobile wireless communications device 132 that requires multiple access technologies is connected to only a single AMF 340.

The AMF 340 forms, for example, a network entity having a network identification 111 and a network address 112 as described above with reference to fig. 1 to 3 and is responsible for terminating or answering messages or communication requests from the first integrated subscriber identity module 151 or the second integrated subscriber identity module 152 to initiate communication of the first integrated subscriber identity module 151 or the second integrated subscriber identity module 152 in the mobile wireless network 110.

The AMF 340 may further process messages or communication requests from the first integrated subscriber identity module 151 or the second integrated subscriber identity module 152 and forward them to the second mobile wireless network, e.g. the mobile wireless network of the communication system 400, to initiate communication of the first integrated subscriber identity module 151 or the second integrated subscriber identity module 152, e.g. in the mobile wireless network.

The SMF or SMF entity 341 is responsible for session management and assigns one or more IP addresses to the corresponding mobile

wireless communication devices

131, 132. SMF 341 also selects UPF 332 and controls UPF 332 in terms of data transmission (e.g., with respect to transmission data 114, 124). When the mobile

wireless communications device

131, 132 has multiple sessions, a respective SMF 341 may be associated with each session to individually control it and possibly provide multiple functions in each session.

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

The AUSF or AUSF entity 351 stores data used to authenticate each mobile

wireless communications device

131, 132, while the UDM352 stores subscription data or subscriber data for the corresponding mobile

wireless communications device

131, 132. The data network DN 333 is not part of the NG core network and provides internet access and carrier services.

The presentation of various reference points of the architecture can be used to represent a refined message flow in Next Generation (NG) standardization. Reference point N1301 is defined as the transport signaling between the first mobile wireless communication device 131 or the second mobile wireless communication device 132 and the AMF 340. Reference points connecting the AN 331 and AMF 340 and the AN 331 and UPF 332 are defined as N2302 and N3303, respectively. There is no reference point between AN 331 and SMF 341, but there is a reference point N11311 between AMF 340 and SMF 341. This indicates that SMF 341 is controlled by AMF 340. N4304 is used by SMF 341 and UPF 332 so that control signals generated by SMF 341 may be used to set UPF 332, and UPF 332 may report its status to SMF 341. N9309 is the reference point between the different UPFs 332, and correspondingly, N14314 is the reference point between the different AMFs 340. N15315 and N7307 are defined so that PCF 342 may apply its criteria to AMF 340 or SMF 341. The AMF 340 requires N12312 to perform authentication for each mobile

wireless communications device

131, 132. N8308 and N10310 are defined because the AMF 340 and SMF 341 require subscription data for each mobile

wireless communication device

131, 132.

Next generation networks aim to enable separation of the user plane and the control plane or control plane. The user plane carries user data traffic and the control plane carries signalling in the network. In fig. 4, 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 extension 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 functions. For example, AMF 340 and SMF 341 are independent functions in the control plane. The separate AMF 340 and SMF 341 allow independent development and expansion. Other control plane functions, such as PCF 342 and AUSF351, can also be separated. The modular functional design shown in fig. 4 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 for support of modularity. The user plane supports interactions such as forwarding operations between different UPFs 332.

There are two types of application scenarios, one being local routing (HR) and the other being local breakout (L BO) so that the first mobile wireless communications device 131 or the second communications device 132 can also send their
