[0041] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0042] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0043] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0044] In the prior art, in order to ensure the safe and stable operation of industrial production, based on the 5G communication system, the terminal external dual-transmitter and selective-receiver device and the network-side UPF often collaborate to achieve dual-transmitter and selective-receiver. However, in the existing solution, when a terminal connected to the dual-transmitter and selective-receiver device changes the SIM card, the contract data in the UDM needs to be manually changed. Therefore, the existing configuration method has the problems of low configuration efficiency and easy configuration errors.

[0045] In view of this, an embodiment of the present application provides a communication configuration method, which enables the client terminal device to automatically modify the corresponding UDM contract data through the network management server when it detects that the SIM card information in its built-in target terminal module has changed, thereby ensuring that the new SUPI of the changed target terminal module still resides in the first VN group. Compared with the existing implementation method, no manual maintenance is required, and automatic configuration can be achieved, configuration efficiency is improved, and configuration errors are avoided.

[0046] The technical solutions of the embodiments of the present application can be applied to various local communication systems, such as: global system for mobile communications (GSM) system, code division multiple access (CDMA) system, wideband code division multiple access (WCDMA) system, general packet radio service (GPRS), long term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD), universal mobile telecommunication system (UMTS), worldwide interoperability for microwave access (WiMAX) communication system, fifth generation (5G) communication system or future new radio access technology (NR), etc.

[0047] Figure 1 Schematic diagram of a network architecture applicable to the method provided in the embodiment of the present application. Figure 1 As shown, the network architecture may be, for example, a non-roaming architecture. The network architecture may specifically include the following network elements:

[0048] 1. Client terminal equipment (user equipment, terminal): can be called user equipment, terminal, access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, wireless communication equipment, user agent or user device. The terminal can also be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication function, a computing device or other processing equipment connected to a wireless modem, a vehicle-mounted device, a wearable device, a client terminal device in a 5G network or a client terminal device in a public land mobile communication network (PLMN) to be evolved in the future, etc. It can also be an end device, a logical entity, an intelligent device, such as a mobile phone, a smart terminal and other client terminal devices, or a server, a gateway, a base station, a controller and other communication equipment, or an Internet of Things device, such as a sensor, an electric meter, a water meter and other Internet of Things (IoT) devices. The embodiments of the present application are not limited to this.

[0049] 2. Access network (AN): provides network access functions for authorized users in a specific area, and can use transmission tunnels of different qualities according to the user level, business requirements, etc. The access network can be an access network that uses different access technologies. There are currently two types of wireless access technologies: 3rd generation partnership project (3GPP) access technology (such as the wireless access technology used in 3G, 4G or 5G systems) and non-3GPP access technology. 3GPP access technology refers to access technology that complies with 3GPP standards and specifications. The access network that uses 3GPP access technology is called a radio access network (RAN), where the access network equipment in the 5G system is called the next generation Node Base station (gNB). Non-3GPP access technology refers to access technology that does not comply with 3GPP standards and specifications, for example, air interface technology represented by access points (APs) in WIFI.

[0050] An access network that implements access network functions based on wireless communication technology can be called a radio access network (RAN). The radio access network can manage wireless resources, provide access services to terminals, and then complete the forwarding of control signals and user data between terminals and the core network.

[0051] The access network equipment may include equipment in the access network that communicates with the wireless terminal over the air interface through one or more sectors. The access network system may be used to convert received air frames to and from Internet Protocol (IP) packets, acting as a router between the wireless terminal and the rest of the access network, which may include an IP network. The wireless access network system may also coordinate the management of attributes of the air interface. It should be understood that the access network equipment includes but is not limited to: evolved node B (eNB), radio network controller (RNC), node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (for example, home evolved node B, or homenode B, HNB), base band unit (BBU), access point (AP) in wireless fidelity (WIFI) system, wireless relay node, wireless backhaul node, transmission point (TRP or transmission point, TP), etc., and can also be a gNB in ​​5G, such as NR, system, or a transmission point (TRP or TP), one or a group of (including multiple antenna panels) antenna panels of a base station in a 5G system, or, it can also be a network node constituting a gNB or a transmission point, such as a baseband unit (BBU)), or a distributed unit (DU), etc.

[0052] In some deployments, the gNB may include a centralized unit (CU) and a DU. The gNB may also include a radio unit (RU). The CU implements some functions of the gNB, and the DU implements some functions of the gNB, for example, the CU implements the functions of the radio resource control (RRC) and packet data convergence protocol (PDCP) layers, and the DU implements the functions of the radio link control (RLC), media access control (MAC) and physical (PHY) layers. Since the information of the RRC layer will eventually become the information of the PHY layer, or be converted from the information of the PHY layer, therefore, under this architecture, high-level signaling, such as RRC layer signaling, can also be considered to be sent by the DU, or by the DU+CU. It can be understood that the access network device can be a CU node, a DU node, or a device including a CU node and a DU node. In addition, the CU may be classified as an access network device in a radio access network (RAN), or the CU may be classified as an access network device in a core network (CN), and no limitation is made here.

[0053] 3. Access and mobility management function (AMF) entity: mainly used for mobility management and access management, etc., and can be used to implement other functions of the mobility management entity (MME) except session management, such as lawful interception or access authorization (or authentication). In the embodiment of the present application, it can be used to implement the functions of the access and mobility management network element.

[0054] 4. Session management function (SMF) entity: mainly used for session management, UE Internet Protocol (IP) address allocation and management, selection of endpoints for manageable user plane functions, policy control, or charging function interfaces, and downlink data notification, etc. In the embodiment of the present application, it can be used to implement the function of the session management network element.

[0055] 5. User Plane Function (UPF) entity: i.e., data plane gateway. It can be used for packet routing and forwarding, or quality of service (QoS) processing of user plane data, etc. User data can be accessed to the data network (DN) through this network element. In the embodiment of the present application, it can be used to implement the function of the user plane gateway.

[0056] 6. Policy control function (PCF) entity: a unified policy framework used to guide network behavior and provide policy rule information to control plane functional network elements (such as AMF, SMF network elements, etc.).

[0057] 7. Unified data management (UDM) entity: used to process user identification, access authentication, registration, or mobility management, etc.

[0058] 8. N3IWF (Non-3GPP Inter Working Function): Responsible for connecting untrusted non-3GPP access networks (such as Wi-Fi) to the 5G core network. The terminal establishes an IPsec tunnel with the N3IWF, and the N3IWF accesses the control plane and user plane of the 5G core network through the N2 interface and the N3 interface respectively.

[0059] 9. Network exposure function (NEF) network element: It serves as the interface between the 5G core network and other external services so that third-party applications and services can securely access network resources and services. Its main functions include: Service exposure: NEF is responsible for exposing services and functions in the 5G network so that external applications and services can call these services; Policy and permission management: NEF ensures that only authenticated and authorized applications and services can access specific network functions; Data conversion: NEF handles the conversion of data formats to ensure compatibility and interoperability between different systems; Traffic filtering and monitoring: NEF can filter and monitor the traffic passing through it to protect the network from malicious behavior; Event notification: NEF can send event notifications to external entities, such as applications, when certain important events occur in the network.

[0060] In this network architecture, Figure 1As shown, the N1 interface is the reference point between the terminal and the AMF entity; the N2 interface is the reference point between the AN and the AMF entity, which is used for sending non-access stratum (NAS) messages, etc.; the N3 interface is the reference point between the (R)AN and the UPF entity, which is used for transmitting user plane data, etc.; the N4 interface is the reference point between the SMF entity and the UPF entity, which is used for transmitting information such as tunnel identification information of the N3 connection, data cache indication information, and downlink data notification messages; the N6 interface is the reference point between the UPF entity and the DN, which is used for transmitting user plane data, etc.

[0061] In addition, if Figure 1 As shown, NEF network elements, network storage function (Network Repository Function, NRF) network elements, application function (Application Function, AF) network elements, PCF network elements, unified data repository (Unified Data Repository, UDR) network elements, UDM network elements, AMF network elements and SMF network elements can use the service-oriented interfaces provided to the outside to achieve communication. For example, the service-oriented interface provided by the NEF network element to the outside is the Nnef interface, the service-oriented interface provided by the UDM network element to the outside is the Nudm interface, the service-oriented interface provided by the AMF network element to the outside is the Namf interface, the service-oriented interface provided by the AF network element to the outside is the Naf interface, the service-oriented interface provided by the SMF network element to the outside is the Nsmf interface, the service-oriented interface provided by the PCF network element to the outside is the Npcf interface, and the service-oriented interface provided by the UDR network element to the outside is the Nudr interface.

[0062] It should be understood that the above-mentioned network architecture applied to the embodiments of the present application is merely an example of a network architecture described from the perspective of a traditional point-to-point architecture and a service-oriented architecture. The network architecture applicable to the embodiments of the present application is not limited to this. Any network architecture that can realize the functions of the above-mentioned network elements is applicable to the embodiments of the present application.

[0063] It should also be understood that Figure 1 The AMF entity, SMF entity, UPF entity, PCF entity, and UDM entity shown in the figure can be understood as network elements used to implement different functions in the core network, for example, they can be combined into network slices as needed. These core network network elements can be independent devices or integrated into the same device to implement different functions, which is not limited in this application.

[0064] In the following text, for the sake of convenience, the entity used to implement AMF will be denoted as AMF, and the entity used to implement PCF will be denoted as PCF. It should be understood that the above naming is only used to distinguish different functions, and does not mean that these network elements are independent physical devices. The present application does not limit the specific form of the above network elements. For example, they can be integrated in the same physical device, or they can be different physical devices. In addition, the above naming is only for the convenience of distinguishing different functions, and should not constitute any limitation on the present application. The present application does not exclude the possibility of using other names in 5G networks and other future networks. For example, in a 6G network, some or all of the above network elements may use the terminology in 5G, or other names may be used. A unified explanation is given here, and no further details will be given below.

[0065] It should also be understood that Figure 1 The interface name between the network elements is only an example. The interface name in the specific implementation may be other names, and this application does not specifically limit this. In addition, the name of the message (or signaling) transmitted between the above network elements is only an example and does not constitute any limitation on the function of the message itself.

[0066] See above Figure 1 It should also be noted that the network structure also includes a network management server, which is connected to the NEF and UPF respectively. The NEF can be used to cooperate with the UDM network element to complete the contract data modification; the UPF can be used to forward the message sent by the client terminal device about creating and modifying the virtual network group. Of course, it should be noted that the functions of the NEF and UPF are not limited to this.

[0067] In addition, see above Figure 1 , the customer premises equipment (CPE) may include multiple terminal modules (UE) supporting dual-transmit selective reception service, for example, it may include two or more, and the customer premises equipment may be mounted with multiple industrial devices. It should be noted that by applying the dual-transmit selective reception service, when the customer premises equipment integrates multiple terminal modules, it can provide multiple transmission selective reception capability guarantee for the downstream industrial equipment, that is, during the data communication process, the original data message can be copied multiple times to ensure higher reliability of data transmission.

[0068] Of course, it should also be noted that the present application does not limit the number of CPEs, and multiple CPEs can be set according to actual application scenarios. The number of industrial devices mounted on a CPE is also not limited, and can be flexibly set according to actual application scenarios.

[0069] Optionally, CPE can be a device installed at the user end, such as a router, modem, telephone, etc.; each terminal module (UE) is a 5G communication module on the CPE, and may include a SIM card, and have a dual-transmit and selective receiving function; industrial equipment can be: including PLC equipment, sensors, actuators (for example, robotic arms, pumps, valves), smart meters, etc., which are not limited here.

[0070] Figure 2 A flow chart of a communication configuration method provided in an embodiment of the present application, which can be applied to Figure 1 A network management server in a network architecture. Figure 2 As shown, the method includes:

[0071] Step 101: receiving a first virtual network group modification request sent by a client terminal device after determining that a user permanent identifier SUPI of any target terminal module has changed, wherein the first virtual network group modification request carries a second SUPI corresponding to the updated target terminal module.

[0072] The client terminal device includes a plurality of terminal modules supporting dual-send and selective-receive services.

[0073] Among them, if the SIM card information of any target terminal module in the client device changes, and causes the SUPI of the target terminal module to be updated from the first SUPI to the second SUPI, the client device can send a first virtual network group (Virtual Network, VN) group modification request to the network management server after detecting the change, and carry the second SUPI through the first VN group modification request, so that the network management server modifies the corresponding UDM subscription data according to the first VN group modification request to ensure that the changed target UE module still resides in the first VN group. The specific modification process is as follows.

[0074] Step 102: According to the first virtual network group modification request, query and obtain a first SUPI corresponding to the target terminal module, where the first SUPI is the corresponding SUPI of the target terminal module before being updated.

[0075] Step 103: forward the first virtual network group modification request to the NEF according to the second SUPI, the first SUPI and the first virtual local area network identifier, so that the NEF deletes the first SUPI from the first virtual network group corresponding to the first virtual local area network identifier according to the first virtual network group modification request, and adds the second SUPI to the first virtual network group.

[0076] The first virtual local area network identifier is a virtual local area network identifier corresponding to the target terminal module pre-configured in the network management server.

[0077] After receiving the first VN group modification request, the network management server can retrieve the local data record according to the first SUPI corresponding to the target terminal module before updating, and determine whether there is a matching first virtual network group. If so, a new data record is generated.<SUPI_new,SUPI_old,VLAN ID_1> , and forwards the first virtual network group modification request to the NEF to request modification of the contract data of the target terminal module. SUPI_new is the second SUPI corresponding to the target terminal module after the update, SUPI_old is the first SUPI corresponding to the target terminal module before the update in the local data record, and VLAN ID_1 is the virtual local area network identifier corresponding to the first SUPI pre-configured in the network management server.

[0078] Among them, after receiving the modification request of the first virtual network group, the NEF can make modifications with network elements such as UDM and SMF to delete the first SUPI corresponding to the target terminal module from the first virtual network group corresponding to the first virtual local area network identifier, so that when the client terminal device detects that the SIM card information in its built-in target terminal module has changed, the network management server can automatically modify the corresponding UDM contract data to ensure that the new SUPI of the changed target terminal module still resides in the first VN group. Compared with the existing implementation method, no manual maintenance is required, and automatic configuration can be achieved, configuration efficiency is improved, and configuration errors are avoided.

[0079] In summary, an embodiment of the present application provides a communication configuration method, which is applied to a network management server, and the management server is communicatively connected with a network opening function NEF. The method includes: receiving a first virtual network group modification request sent by a client terminal device after determining that a user permanent identifier SUPI of any target terminal module has changed, the first virtual network group modification request carrying a second SUPI corresponding to the target terminal module after being updated; querying and acquiring the first SUPI corresponding to the target terminal module according to the first virtual network group modification request; forwarding the first virtual network group modification request to the NEF according to the second SUPI, the first SUPI and the first virtual local area network identifier, so that the NEF deletes the first SUPI from the first virtual network group corresponding to the first virtual local area network identifier according to the first virtual network group modification request, and adds the second SUPI to the first virtual network group, so that when the client terminal device detects that the SIM card information in the built-in target terminal module has changed, the corresponding UDM subscription data can be automatically modified through the network management server to ensure that the new SUPI of the changed target terminal module still resides in the first VN group. Compared with the existing implementation method, no manual maintenance is required, and automatic configuration can be achieved, configuration efficiency is improved, and configuration errors can be avoided.

[0080] Figure 3A flow chart of another communication configuration method provided in an embodiment of the present application, in an optional implementation manner, such as Figure 3 As shown, after forwarding the first virtual network group modification request to the NEF according to the second SUPI, the first SUPI and the first virtual local area network identifier, the method further includes:

[0081] Step 201: Return a first virtual network group modification response corresponding to a first virtual network group modification request to a client terminal device.

[0082] Among them, the first virtual network group modification response is generated by NEF after receiving the first contract data modification response sent by the unified data management UDM, the first contract data modification response is generated by UDM after modifying the contract data according to the first contract data modification request sent by NEF, and the first contract data modification request is generated by NEF according to the first virtual network group modification request.

[0083] Optionally, after receiving the first virtual network group modification request sent by the network management server, NEF can generate a first contract data modification request and send it to UDM, requesting that the first SUPI (ie, SUPI_old) be deleted from the first VN group and the second SUPI (ie, SUPI_new) be added to the first VN group.

[0084] After receiving the first contract data modification request from the NEF, the UDM modifies the local contract data and returns the generated first contract data modification response to the NEF. The NEF can generate a first virtual network group modification response based on this, and further return the first virtual network group modification response to the network management server. The network management server returns the first virtual network group modification response to the client terminal device. Then, at this time, the client terminal device can know that the first SUPI has been deleted from the first virtual network group corresponding to the first virtual local area network identifier, and the second SUPI is added to the first virtual network group, and then the client terminal device can subsequently perform related communications based on the first virtual network group.

[0085] By using the embodiments of the present application, it is possible to ensure that a virtual network group can be successfully created through communication between NEF and UDM.

[0086] In an optional implementation, the UDM is further configured to generate a modification event according to the first subscription data modification response and send it to the session management function SMF, so that the SMF initiates a first PDU session modification process for the target terminal module.

[0087] Based on the above description, after completing the contract data modification, UDM can generate the first modification event (ie, Nudm_SDM_Notification_1), triggering SMF to initiate a PDU session modification process for the target terminal module in the customer terminal device, so that the above-configured first virtual network group can take effect and ensure subsequent reliable communication.

[0088] Figure 4 A flow chart of another communication configuration method provided in an embodiment of the present application, in an optional implementation manner, such as Figure 4 As shown, the above method also includes:

[0089] Step 401: Receive a third virtual network group modification request sent by a client terminal device, where the third virtual network group modification request carries a third SUPI corresponding to each terminal module in the client terminal device.

[0090] The third virtual network group modification request is generated when the client terminal device does not receive data sent by the industrial device within a preset time period, and the client terminal device is mounted with multiple industrial devices.

[0091] Based on the above description, in some embodiments, during the communication process, the client terminal device can communicate with multiple industrial devices mounted thereon based on the created third VN group. It can be understood that if the client terminal device does not receive the data sent by the industrial device within the preset time period, it means that the industrial device is offline or the data sending is completed. At this time, the client terminal device can send a third virtual network group modification request to the management server. The third virtual network group modification request can carry the third SPUI corresponding to each terminal module, so as to remove the third SUPI corresponding to each terminal module integrated in the client terminal device from the third virtual network group through the management server, so as to avoid continuing to occupy the third virtual network group after the industrial device is offline, thereby affecting the normal communication between the client terminal device and other devices.

[0092] Step 402: According to each third SUPI in the third virtual network group modification request, query and obtain a third virtual local area network identifier corresponding to each third SUPI.

[0093] Step 403: forward the third virtual network group modification request to the NEF according to each third SUPI and the third virtual LAN identifier, so as to delete each third SUPI from the third virtual network group corresponding to the third virtual LAN identifier through the NEF.

[0094] After receiving the third virtual network group modification request, the management server uses each third SUPI (SUPI_3) as an index to retrieve the corresponding third virtual local area network identifier (VLAN ID_3) locally, and generates a data record if there is a matching record:<SUPI_3,VLAN ID_3> , obtain the third virtual local area network identifier (VLAN ID_3) corresponding to each third SUPI.

[0095] Furthermore, the network management server may send a third virtual network group modification request to the NEF, requesting modification of the third VN group with an external identifier of VLAN ID_3, so as to delete the third SUPI corresponding to each terminal module in the client terminal device from the third VN group.

[0096] Optionally, after receiving the third virtual network group modification request, NEF initiates a third contract data modification request to UDM, requesting that each third SUPI be removed from the third VN group; UDM can modify the contract data according to the third contract data modification request, remove each third SUPI from the third VN group, and generate a third contract data modification response and return it to NEF. NEF can generate a third virtual network group modification response according to the third contract data modification response and return it to the network management server, and the network management server further returns the third virtual network group modification response to the client terminal device. It can be understood that at this time, the client terminal device can know the modification status of the current third virtual network group according to the third virtual network group modification response, and realize the synchronous update of the modification result.

[0097] By applying the embodiments of the present application, if the client terminal device does not receive the data sent by the industrial equipment within a preset time period, the corresponding contract data can be modified through the network management server, and the third SUPI corresponding to each terminal module in the client terminal device can be removed from the third VN group, thereby modifying the third VN group and avoiding continuing to occupy the third virtual network group after the industrial equipment is offline, which affects the normal communication between the client terminal device and other devices.

[0098] In an optional embodiment, the client terminal device is configured to: if a modification success response or a creation success response of the first virtual network group is received, start a preset timer to wait for receiving data sent by the industrial device; if data sent by the industrial device is received within a preset time period, reset the preset timer and start timing; if no data sent by the industrial device is received after the preset timer expires, the client terminal device sends a third virtual network group modification request to the management server.

[0099] Based on the above description, after the client terminal device receives a modification success response or a creation success response of the third VN group from the network management server, it can create a start timer locally. If data sent by any industrial device is received within a preset time period (for example, 1 group, 5 minutes, etc.), the preset timer is reset and the timing is started, that is, it is cleared and started, waiting to receive new data, and the process is repeated; if no data sent by the industrial device is received after the preset timer expires, it can be considered that the industrial device is offline. At this time, the client terminal device can send a third virtual network group modification request to the management server.

[0100] It should be noted that the creation of the third virtual network group can refer to the following steps 501 and 502. Of course, if modification is required, the above steps 101 and 102 can be referred to.

[0101] By applying the embodiments of the present application, real-time monitoring of the online status of industrial equipment is achieved, and the virtual network group is dynamically modified according to the monitoring results, thereby improving the flexibility and applicability of the method of the present application.

[0102] Figure 5 A flow chart of another communication configuration method provided in an embodiment of the present application, in an optional implementation manner, such as Figure 5 As shown, the above method also includes:

[0103] Step 501: Receive a fourth virtual local area network identifier creation request sent by a client terminal device according to an ARP response sent by a target industrial device.

[0104] Among them, the ARP response is generated by the target industrial device based on the ARP request sent by the client terminal device; the ARP request is generated by the client terminal device based on the target device address of the target industrial device that needs to provide dual-send and selective reception services issued by the management server and the fourth virtual LAN identifier associated with the target industrial device, and the client terminal device is mounted with multiple industrial devices.

[0105] The network management server may be pre-configured with the target device address (eg, IP address) of the target industrial device for which the dual-send and selective-receive service is required and its associated fourth virtual local area network identifier (VLAN ID_4).

[0106] Optionally, the client terminal device can be configured to read the fourth SUPI of each terminal module built into it after accessing the communication network, and report the information to the network management server. After receiving each fourth SUPI, the network management server can send the target device address of the target industrial device and its associated fourth virtual local area network identifier to the client terminal device.

[0107] The client terminal device can generate an ARP request based on the target device address and its associated fourth virtual LAN identifier and send it to each industrial device mounted on it, and receive an ARP response sent by the target industrial device; based on the ARP response, a fourth virtual LAN identifier creation request is sent to the network management server through UPF, requesting the creation of a fourth VN group in UDM.

[0108] Step 502: Send a fourth subscription data modification request to the NEF according to the fourth virtual LAN identifier creation request, so as to create a fourth virtual network group corresponding to the fourth virtual LAN identifier through the NEF, and add each fourth SUP to the fourth virtual network group.

[0109] After receiving the fourth virtual local area network identifier creation request, the network management server generates the following data record:<SUPI_4,VLAN ID_4> SUPI_4 includes the fourth SUPI identifier of each built-in terminal module reported by the client terminal device, and VLAN ID_4 is the fourth virtual local area network identifier.

[0110] Furthermore, the network management server sends a fourth subscription data modification request to the NEF based on the generated data record, requesting to modify the subscription data in the UDM, and through the modification, to create a fourth VN group with VLAN ID_4 as the external identifier, and add each fourth SUPI to the fourth virtual network group.

[0111] It should be noted that, when NEF receives the fourth contract data modification request, it can forward the fourth contract data request to UDM. After receiving the fourth contract data modification request from NEF, UDM modifies the local contract data and returns the modification result to NEF. After UDM completes the contract data modification, it generates the corresponding fourth modification event (Nudm_SDM_Notification_4) event, triggering SMF to initiate two PDU session modification processes for the terminal module in the client terminal device. NEF returns the response of UDM completing the fourth contract data modification to the network management server, and the network management server generates a response for the creation of the fourth VN group and returns it to the client terminal device. For the description of this part, please refer to the aforementioned related content, which will not be repeated here.

[0112] Figure 6 A flow chart of another communication configuration method provided in an embodiment of the present application. In an optional implementation, as Figure 6 As shown, before the receiving of the fourth virtual local area network identifier creation request sent by the client terminal device according to the ARP response sent by the target industrial device, it also includes:

[0113] Step 601: Receive a fourth SUPI identifier of each terminal module reported by a client terminal device.

[0114] Step 602: According to each fourth SUPI identifier, the target device address of the target industrial device for which the dual-send and selective-receive service is required and the fourth virtual local area network identifier associated with the target industrial device are sent to the client terminal device, so that the client terminal device sends an ARP request to each industrial device mounted thereon according to the target device address, and receives an ARP response sent by the target industrial device.

[0115] The target industrial device for which the dual-send and selective-receive service is required may be one or more of the multiple industrial devices mounted on the client terminal device, which is not limited here.

[0116] The client terminal device can be configured to read the fourth SUPI identifier of each terminal module built into it after accessing the communication network, and report the information to the network management server; the network management server returns the target device address (for example, IP address) of the target industrial device that needs to provide dual-send and selective-receive service in the client terminal device and its associated fourth virtual local area network identifier (VLAN ID_4) to the client terminal device.

[0117] After the client terminal device receives the IP address of the target industrial device, it uses these IP addresses as query target addresses and sends ARP requests to the mounted industrial devices through the local network port. After the industrial device receives the ARP request, it determines whether the query target address is the local address. If so, the industrial device returns its MAC address to the client terminal device. Otherwise, the industrial device ignores the ARP request.

[0118] By applying the embodiments of the present application, it is possible to carry out targeted configuration of target industrial equipment that provides dual-send and selective-receive services, thereby improving the applicability and flexibility of the method of the present application.

[0119] In an optional implementation manner, the client terminal device is configured to detect and determine whether the user permanent identifier SUPI of each terminal module changes according to a preset frequency.

[0120] In some embodiments, in order to ensure that when a user permanent identifier SUPI of any terminal module in the client terminal device changes, it can be detected in time, the client terminal device can be set to obtain the SUPI of each terminal module according to a preset frequency, and compare it with the historical SUPI of each terminal module. If they are the same, it is determined that the SUPI of the terminal module has not changed. Otherwise, it is determined that the SUPI of the terminal module has changed. At this time, relevant configuration can be performed with reference to the contents of steps 101 to 103 above. The specific configuration method can be referred to the aforementioned related content, which will not be repeated here.

[0121] In summary, by applying the embodiments of the present application, the client terminal device detects the local downstream industrial equipment and, in combination with the dual-transmission and selective reception configuration information of the industrial equipment issued by the network management server, determines whether the local downstream industrial equipment that needs to provide dual-transmission and selective reception protection is connected. If so, the client terminal device modifies the corresponding contract data in the UDM of the 5G network through the network management server to complete the creation of the corresponding VN group; in addition, the client terminal device can also continuously monitor the connection status of the local downstream industrial equipment. If it is detected that the industrial equipment with dual-transmission and selective reception protection is offline, the corresponding UDM contract data is modified through the network management server, and the SUPI corresponding to the terminal module is removed from the corresponding VN group; further, the client terminal device can also continuously detect the SIM card information in its built-in terminal module. If there is a change, the corresponding UDM contract data is modified through the network management server to ensure that the changed terminal module still resides in the VN group.

[0122] Based on the present application, by automatically configuring special contract data for different terminal modules in the same customer terminal device in the UDM so that they belong to the same VN group, it can be ensured that different terminal modules in the same customer terminal device establish a PDU session connection with the same UPF to realize dual-send and selective reception service. Compared with the existing technology, it can avoid the problem of low configuration efficiency when there are many terminal modules to be configured by manual configuration, and avoid configuration errors; furthermore, the present application also supports the situation where the contract data in the UDM needs to be changed accordingly after the SIM card of some terminal modules in the customer terminal device is replaced, so that automatic configuration can be realized, the configuration efficiency is improved, and the configuration effect is guaranteed.

[0123] In an optional implementation, the above communication configuration method may be applied to a client terminal device, the client terminal device includes a plurality of terminal modules supporting a dual-send and selective-receive service, and the method includes:

[0124] If it is determined that the user permanent identifier SUPI of any target terminal module has changed, a first virtual network group modification request is sent to the network management server, so that the network management server queries and obtains a first SUPI corresponding to the target terminal module according to the first virtual network group modification request, where the first SUPI is the corresponding SUPI of the target terminal module before being updated; and forwards the first virtual network group modification request to the NEF according to the second SUPI, the first SUPI and the first virtual local area network identifier.

[0125] Among them, the NEF is used to delete the first SUPI corresponding to the target terminal module from the first VN group corresponding to the first virtual local area network identifier according to the first virtual network group modification request, and add the terminal corresponding to the second SUPI to the first VN group. The first virtual local area network identifier is pre-configured in the network management server, and the first virtual network group modification request carries the second SUPI corresponding to the updated target terminal module.

[0126] By applying the embodiments of the present application, when the client terminal device detects that the SIM card information in its built-in target terminal module has changed, the corresponding UDM contract data can be automatically modified through the network management server to ensure that the new SUPI of the changed target terminal module still resides in the first VN group. Compared with the existing implementation method, no manual maintenance is required, and automatic configuration can be achieved, configuration efficiency is improved, and configuration errors can be avoided.
