Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a communication configuration method and electronic device. Background Technology

[0002] Industrial applications are complex and diverse, with varying communication needs. As 5G penetrates from auxiliary production to core production, reliability requirements are gradually increasing. For example, industrial production involves numerous actions such as flipping, lifting, clamping, and conveying. The bending caused by the connection method of drag chain cables can lead to cable failures, resulting in production line downtime and difficulties in fault location.

[0003] In existing technologies, in order to ensure the safe and stable operation of industrial production, based on 5G communication systems, dual-transmission and reception are often achieved through collaboration between external dual-transmission and reception equipment on the terminal and the network-side UPF.

[0004] However, in the existing scheme, when a terminal connected to a dual-transmitter selector device changes its SIM card, the subscription 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. Summary of the Invention

[0005] The purpose of this application is to address the shortcomings of the prior art by providing a communication configuration method and electronic device that can achieve automated configuration, improve configuration efficiency, and avoid configuration errors.

[0006] To achieve the above objectives, the technical solutions adopted in the embodiments of this application are as follows:

[0007] In a first aspect, the present invention provides a communication configuration method applied to a network management server, wherein the management server is communicatively connected to the Network Open Function (NEF), the method comprising:

[0008] The client terminal device receives a first virtual network group modification request sent after determining that the user permanent identifier (SUPI) of any target terminal module has changed. The first virtual network group modification request carries the second SUPI corresponding to the updated target terminal module. The client terminal device includes multiple terminal modules that support dual-transmit selective reception service.

[0009] Based on the first virtual network group modification request, query and obtain the first SUPI corresponding to the target terminal module. The first SUPI is the one that the target terminal module corresponds to before the update.

[0010] Based on the second SUPI, the first SUPI, and the first VLAN ID, the first VLAN group modification request is forwarded to the NEF, so that the NEF deletes the first SUPI from the first VLAN group corresponding to the first VLAN ID and adds the second SUPI into the first VLAN group. The first VLAN ID is the VLAN ID corresponding to the target terminal module pre-configured in the network management server.

[0011] In an optional implementation, after forwarding the first virtual network group modification request to the NEF based on the second SUPI, the first SUPI, and the first virtual LAN identifier, the method further includes:

[0012] The first virtual network group modification response corresponding to the first virtual network group modification request is returned to the client terminal device. The first virtual network group modification response is generated by the NEF after receiving the first subscription data modification response sent by the Unified Data Management UDM. The first subscription data modification response is generated by the UDM after modifying the subscription data according to the first subscription data modification request sent by the NEF. The first subscription data modification request is generated by the NEF according to the first virtual network group modification request.

[0013] In an optional implementation, the UDM is further configured to generate a modification event based on 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.

[0014] In an optional implementation, the method further includes:

[0015] The client terminal device receives a third virtual network group modification request sent by the client terminal device. The third virtual network group modification request carries the SUPI corresponding to each terminal module in the client terminal device. The third virtual network group modification request is generated by the client terminal device when it does not receive data sent by industrial equipment within a preset time period. The client terminal device is equipped with multiple industrial devices.

[0016] Based on each third SUPI in the third virtual network group modification request, query and obtain the third virtual local area network identifier corresponding to each third SUPI;

[0017] Based on each of the third SUPIs and the third VLAN ID, the third VLAN group modification request is forwarded to the NEF so that the NEF can remove each of the third SUPIs from the third VLAN group corresponding to the third VLAN ID.

[0018] In an optional implementation, the client terminal device is configured to: if it receives a successful modification response or a successful creation response for the first virtual network group, start a preset timer to wait for data sent by the industrial device; if it receives data sent by the industrial device within a preset time period, reset the preset timer and start timing; if it still does not receive data sent by the industrial device after the preset timer expires, the client terminal device sends the third virtual network group modification request to the management server.

[0019] In an optional implementation, the method further includes:

[0020] The system receives a fourth virtual local area network (VLAN) identifier creation request sent by a client terminal device based on an ARP response sent by a target industrial device. The ARP response is generated by the target industrial device based on an 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 requiring dual-transmission / selective reception service, as issued by the management server, and the fourth VLAN identifier associated with the target industrial device. The client terminal device has multiple industrial devices mounted on it.

[0021] Based on the fourth VLAN ID creation request, a fourth subscription data modification request is sent to the NEF to create a fourth virtual network group corresponding to the fourth VLAN ID through the NEF, and each fourth SUP is added to the fourth virtual network group.

[0022] In an optional implementation, before receiving the fourth Virtual LAN Identifier Creation Request sent by the client terminal device based on the ARP response sent by the target industrial equipment, the method further includes:

[0023] Receive the fourth SUPI identifier of each terminal module reported by the customer terminal equipment;

[0024] Based on each fourth SUPI identifier, the client terminal device sends the target device address of the target industrial device for which dual-transmit selective reception service is required, and the fourth virtual LAN identifier associated with the target industrial device, so that the client terminal device sends ARP requests to each industrial device it is connected to based on the target device address, and receives ARP responses sent by the target industrial device.

[0025] In an optional implementation, the client terminal device is configured to detect whether the user permanent identifier SUPI of each terminal module has changed according to a preset frequency.

[0026] In a second aspect, the present invention provides a communication configuration method applied to a client terminal device, the client terminal device including multiple terminal modules supporting dual-transmit selective reception service, the method comprising:

[0027] If it is determined that the User Permanent Identifier (SUPI) of any target terminal module has changed, a first Virtual Network Group (VNR) modification request is sent to the network management server. The network management server then queries and obtains the first SUPI corresponding to the target terminal module based on the first VNR modification request. The first SUPI is the one corresponding to the target terminal module before the update. Based on the second SUPI, the first SUPI, and the first Virtual Local Area Network (VLAN) identifier, the first VNR modification request is forwarded to the Network Open Function (NEF).

[0028] The NEF is used to delete the first SUPI from the first VN group corresponding to the first virtual LAN identifier and add the terminal corresponding to the second SUPI into the first VN group according to the first virtual network group modification request. The first virtual LAN identifier is pre-configured by the network management server for the target terminal module. The first virtual network group modification request carries the second SUPI corresponding to the target terminal module after the update.

[0029] Thirdly, the present invention provides an electronic device, comprising: a processor, a storage medium, and a bus, wherein the storage medium stores machine-readable instructions executable by the processor, and when the electronic device is running, the processor communicates with the storage medium via the bus, and the processor executes the machine-readable instructions to perform the steps of the communication configuration as described in any of the foregoing embodiments.

[0030] The beneficial effects of this application are:

[0031] The communication configuration method and electronic device provided in this application include: receiving a first virtual network group modification request sent by a client terminal device after determining that the 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; querying and obtaining the first SUPI corresponding to the target terminal module according to the first virtual network group modification request; and forwarding the first virtual network group modification request to the NEF according to the second SUPI, the first SUPI, and the first virtual LAN identifier, so that the NEF deletes the first SUPI from the first virtual network group corresponding to the first virtual LAN identifier and adds the second SUPI into the first virtual network group. This enables the client terminal device to automatically modify the corresponding UDM subscription data through the network management server when it detects that the SIM card information in its built-in target terminal module has changed, ensuring that the new SUPI of the changed target terminal module still resides in the first VN group. Compared with the existing implementation, this eliminates the need for manual maintenance, achieves automated configuration, improves configuration efficiency, and avoids configuration errors.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0042] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0043] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0044] In existing technologies, to ensure the safe and stable operation of industrial production, 5G communication systems often employ external dual-transmission and reception devices on the terminal and network-side UPF collaboration to achieve dual-transmission and reception. However, in existing solutions, when a terminal connected to the dual-transmission and reception device changes its SIM card, the subscription data in the UDM needs to be manually modified. Therefore, existing configuration methods suffer from low configuration efficiency and are prone to configuration errors.

[0045] In view of this, the present application provides a communication configuration method that enables a client terminal device to automatically modify the corresponding UDM subscription data through a network management server when it detects a change in the SIM card information in its built-in target terminal module. This ensures that the new SUPI of the changed target terminal module still resides in the first VN group. Compared with the existing implementation method, it eliminates the need for manual maintenance, achieves automated configuration, improves configuration efficiency, and avoids configuration errors.

[0046] The technical solutions of this application embodiment 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) system, Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication system, 5th Generation (5G) communication system, or future new radio access technology (NR), etc.

[0047] Figure 1 This is a schematic diagram of the network architecture applicable to the methods provided in the embodiments of this application. For example... Figure 1 As shown, this network architecture can be, for example, a non-roaming architecture. Specifically, this network architecture may include the following network elements:

[0048] 1. User equipment (terminal): This can be referred to as 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. A terminal can also be a cellular phone, cordless phone, session initiation protocol (SIP) phone, wireless local loop (WLL) station, personal digital assistant (PDA), handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, vehicle-mounted device, wearable device, user equipment in a 5G network, or user equipment in a future public land mobile network (PLMN), etc. It can also be an end device, logical entity, smart device, such as a mobile phone, smart terminal, or other user equipment; or a server, gateway, base station, controller, or other communication device; or an Internet of Things (IoT) device, such as a sensor, electricity meter, water meter, etc. This application does not limit this specific type of device.

[0049] 2. Access Network (AN): Provides network access functionality for authorized users in a specific area and can use transmission tunnels of different quality depending on the user's level and service requirements. Access networks can employ different access technologies. Currently, there are two types of radio access technologies: 3rd Generation Partnership Project (3GPP) access technologies (such as those used in 3G, 4G, or 5G systems) and non-3GPP access technologies. 3GPP access technologies refer to access technologies that conform to 3GPP standards and specifications. Access networks using 3GPP access technologies are called radio access networks (RANs). In 5G systems, access network equipment is called next-generation node base stations (gNBs). Non-3GPP access technologies refer to access technologies that do not conform to 3GPP standards and specifications, such as air interface technologies represented by access points (APs) in Wi-Fi.

[0050] An access network that uses wireless communication technology to implement access network functions can be called a radio access network (RAN). A RAN manages radio resources, provides access services to terminals, and facilitates the forwarding of control signals and user data between terminals and the core network.

[0051] The access network equipment may include devices within the access network that communicate with wireless terminals via one or more sectors on the air interface. The access network system may be used to convert received air frames to and from Internet Protocol (IP) packets, and act 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 attribute management of the air interface. It should be understood that 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 (e.g., home evolved node B, or home node B, HNB), base band unit (BBU), access point (AP), wireless relay node, wireless backhaul node, transmission and reception point (TRP or transmission point, TP) in a wireless fidelity (WIFI) system, and can also be gNB in ​​5G, such as NR, or transmission point (TRP or TP), one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G system, or can also be network nodes constituting a gNB or transmission point, such as base band unit (BBU) or distributed unit (DU), etc.

[0052] In some deployments, a gNB may include a centralized unit (CU) and a DU. The gNB may also include a radio unit (RU). The CU implements some of the gNB's functions, and the DU implements others. For example, the CU implements radio resource control (RRC) and packet data convergence protocol (PDCP) layer functions, while the DU implements radio link control (RLC), media access control (MAC), and physical (PHY) layer functions. Since RRC layer information ultimately becomes PHY layer information, or is derived from PHY layer information, in this architecture, higher-layer signaling, such as RRC layer signaling, can be considered to be sent by the DU, or by the DU+CU. It is understood that access network equipment can be a CU node, a DU node, or a device including both CU and DU nodes. Furthermore, the CU can be classified as an access network device in the radio access network (RAN) or as an access network device in the core network (CN), without any restrictions.

[0053] 3. Access and Mobility Management Function (AMF) Entity: Primarily used for mobility management and access management, it can implement functions of the Mobility Management Entity (MME) other than session management, such as lawful interception or access authorization (or authentication). In the embodiments of this application, it can be used to implement the functions of the access and mobility management network element.

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

[0055] 5. User Plane Function (UPF) Entity: This is the data plane gateway. It can be used for packet routing and forwarding, or for quality of service (QoS) processing of user plane data. User data can access the data network (DN) through this network element. In this embodiment, it can be used to implement the functions of a user plane gateway.

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

[0057] 7. Unified Data Management (UDM) entity: Used to handle user identification, access authentication, registration, or mobility management, etc.

[0058] 8. N3IWF (Non-3GPP Interworking 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, which accesses the control plane and user plane of the 5G core network through the N2 and N3 interfaces, respectively.

[0059] 9. Network Exposure Function (NEF) Element: Serving as the interface between the 5G core network and other external services, enabling third-party applications and services to securely access network resources and services. Its main functions include: Service Exposure: The NEF is responsible for exposing services and functions in the 5G network, allowing external applications and services to invoke these services; Policy and Access Management: The NEF ensures that only authenticated and authorized applications and services can access specific network functions; Data Conversion: The NEF handles data format conversion to ensure compatibility and interoperability between different systems; Traffic Filtering and Monitoring: The NEF can filter and monitor traffic passing through it to protect the network from malicious attacks; Event Notification: The NEF can send event notifications to external entities, such as applications, when certain important events occur in the network.

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

[0061] In addition, such as Figure 1 As shown, NEF network elements, Network Repository Function (NRF) network elements, Application Function (AF) network elements, PCF network elements, Unified Data Repository (UDR) network elements, UDM network elements, AMF network elements, and SMF network elements can communicate using externally provided service interfaces. For example, the externally provided service interface for NEF network elements is the Nnef interface, for UDM network elements it is the Nudm interface, for AMF network elements it is the Namf interface, for AF network elements it is the Naf interface, for SMF network elements it is the Nsmf interface, for PCF network elements it is the Npcf interface, and for UDR network elements it is the Nudr interface.

[0062] It should be understood that the network architecture described above in the embodiments of this 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 this application is not limited to this, and any network architecture that can realize the functions of the above-mentioned network elements is applicable to the embodiments of this application.

[0063] It should also be understood that Figure 1 The AMF, SMF, UPF, PCF, and UDM entities shown can be understood as network elements in the core network used to implement different functions, such as network slices that can be combined as needed. These core network elements can be independent devices or integrated into the same device to implement different functions; this application does not limit this.

[0064] In the following text, for ease of explanation, the entity used to implement AMF will be referred to as AMF, and the entity used to implement PCF will be referred to as PCF. It should be understood that the above naming is only for distinguishing different functions and does not mean that these network elements are independent physical devices. This application does not limit the specific form of the above network elements; for example, they can be integrated into the same physical device or they can be different physical devices. Furthermore, the above naming is only for distinguishing different functions and should not constitute any limitation on this application. This application does not exclude the possibility of using other naming in 5G networks and other future networks. For example, in 6G networks, some or all of the above network elements may use the terminology from 5G, or they may use other names, etc. This is explained uniformly here and will not be repeated below.

[0065] It should also be understood that Figure 1 The interface names between the various network elements are merely examples; in actual implementations, the interface names may differ, and this application does not impose any specific limitations on them. Furthermore, the names of the messages (or signaling) transmitted between the aforementioned network elements are also merely examples and do not constitute any limitation on the function of the messages themselves.

[0066] See above Figure 1 It should also be noted that this network structure includes a network management server, which communicates with both the NEF and UPF. The NEF can be used in conjunction with UDM network elements to modify subscription data; the UPF can be used to forward messages sent by client terminal devices regarding the creation and modification of virtual network groups. Of course, it should be noted that the functions of the NEF and UPF are not limited to these.

[0067] In addition, see the above. Figure 1 Customer Premises Equipment (CPE) can include multiple terminal modules (UEs) supporting dual-transmit selective reception service. For example, it can include two or more, and the CPE can be connected to multiple industrial devices. It should be noted that by applying the dual-transmit selective reception service, when the CPE integrates multiple terminal modules, it can provide downstream industrial devices with dual-transmit selective reception capability assurance. That is, during data communication, the original data packets can be copied multiple times, ensuring higher reliability of data transmission.

[0068] Of course, it should also be noted that this application does not limit the number of CPEs. Multiple CPEs can be set according to the actual application scenario, nor does it limit the number of industrial devices mounted on each CPE. The number of CPEs can be set flexibly according to the actual application scenario.

[0069] Optionally, the 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 dual transmit and receive functions; the industrial equipment can include PLC equipment, sensors, actuators (such as robotic arms, pumps, valves), smart meters, etc., without limitation.

[0070] Figure 2 This is a flowchart illustrating a communication configuration method provided in an embodiment of this application. This method can be applied to... Figure 1 Network management servers in a network architecture. For example... Figure 2 As shown, the method includes:

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

[0072] The customer terminal equipment includes multiple terminal modules that support dual-transmit and selective reception services.

[0073] If the SIM card information of any target terminal module in the client device changes, causing 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 (VN) group modification request to the network management server after detecting the change. The second SUPI is carried in the first VN group modification request, so that the network management server can modify the corresponding UDM subscription data according to the first VN group modification request, ensuring that the target UE module that has changed still resides in the first VN group. The specific modification process is as follows.

[0074] Step 102: Based on the modification request of the first virtual network group, query and obtain the first SUPI corresponding to the target terminal module. The first SUPI is the one that the target terminal module corresponds to before the update.

[0075] Step 103: Based on the second SUPI, the first SUPI, and the first VLAN ID, forward the first virtual network group modification request to NEF, so that NEF can delete the first SUPI from the first virtual network group corresponding to the first VLAN ID and add the second SUPI into the first virtual network group according to the first virtual network group modification request.

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

[0077] Upon receiving a modification request for the first VN group, the network management server can retrieve local data records based on the first SUPI corresponding to the target terminal module before the update, determine whether a matching first virtual network group exists, and if so, generate a new data record.<SUPI_new,SUPI_old,VLAN ID_1> The system then forwards the first virtual network group modification request to NEF to request modifications to the subscription data of the target terminal module. Here, 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 LAN identifier corresponding to the first SUPI pre-configured in the network management server.

[0078] Upon receiving the modification request for the first virtual network group, NEF can modify network elements such as UDM and SMF to remove the first SUPI corresponding to the target terminal module from the first virtual network group corresponding to the first virtual LAN identifier. This enables the client terminal device to automatically modify the corresponding UDM subscription data through the network management server when it detects a change in the SIM card information in its built-in target terminal module. This ensures that the new SUPI of the changed target terminal module still resides in the first VN group. Compared with the existing implementation method, it eliminates the need for manual maintenance, achieves automated configuration, improves configuration efficiency, and avoids configuration errors.

[0079] In summary, this application provides a communication configuration method applied to a network management server. The management server is connected to the Network Open Function (NEF) for communication. The method includes: receiving a first virtual network group modification request sent by a client terminal device after determining that the User Permanent Identifier (SUPI) of any target terminal module has changed. The first virtual network group modification request carries a second SUPI corresponding to the updated target terminal module. Based on the first virtual network group modification request, the method queries and obtains the first SUPI corresponding to the target terminal module. Based on the second SUPI, the first SUPI, and the first virtual LAN identifier, the method forwards the first virtual network group modification request to the NEF, so that the NEF deletes the first SUPI from the first virtual network group corresponding to the first virtual LAN identifier and adds the second SUPI to the first virtual network group. This enables the client terminal device to automatically modify the corresponding UDM subscription data through the network management server when it detects a change in the SIM card information in its built-in target terminal module. This ensures that the new SUPI of the changed target terminal module still resides in the first VN group. Compared with existing implementations, this method eliminates the need for manual maintenance, achieves automated configuration, improves configuration efficiency, and avoids configuration errors.

[0080] Figure 3This is a flowchart illustrating another communication configuration method provided in an embodiment of this application. In optional implementations, such as... Figure 3 As shown, after forwarding the first virtual network group modification request to NEF based on the second SUPI, the first SUPI, and the first virtual LAN identifier, the process further includes:

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

[0082] Specifically, the first virtual network group modification response is generated by NEF upon receiving the first subscription data modification response sent by the Unified Data Management (UDM). The first subscription data modification response is generated by UDM after modifying the subscription data according to the first subscription data modification request sent by NEF. The first subscription 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 subscription data modification request and send it to UDM, requesting that the first SUPI (i.e., SUPI_old) be deleted from the first VN group and the second SUPI (i.e., SUPI_new) be added to the first VN group.

[0084] After receiving the first subscription data modification request from NEF, UDM modifies its local subscription data and returns the generated first subscription data modification response to NEF. NEF can then generate a first virtual network group modification response and further return it to the network management server. The network management server then returns the first virtual network group modification response to the client terminal device. At this point, the client terminal device can know from the first virtual network group corresponding to the first virtual LAN identifier that the first SUPI has been deleted and the second SUPI has been added to the first virtual network group. Subsequently, the client terminal device can perform relevant communications based on the first virtual network group.

[0085] By applying the embodiments of this application, communication between NEF and UDM can ensure that virtual network groups can be successfully created.

[0086] In an optional implementation, the UDM is further configured to generate a modification event based on 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 modification of the subscription data, UDM can generate a first modification event (i.e., Nudm_SDM_Notification_1), triggering SMF to initiate a PDU session modification process for the target terminal module in the client terminal device, so that the first virtual network group configured above can take effect and ensure reliable communication thereafter.

[0088] Figure 4 This is a flowchart illustrating another communication configuration method provided in an embodiment of this application. In optional implementations, such as... Figure 4 As shown, the above method also includes:

[0089] Step 401: Receive the third virtual network group modification request sent by the client terminal device. The third virtual network group modification request carries the 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 equipment within a preset time period. The client terminal device is connected to multiple industrial devices.

[0091] Based on the above description, in some embodiments, during communication, the client terminal device can communicate with multiple industrial devices connected to it based on the created third VN group. It is understood that if the client terminal device does not receive data sent by the industrial device within a preset time period, it indicates that the industrial device is offline or the data transmission is complete. 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 that the management server can remove the third SUPI corresponding to each terminal module integrated in the client terminal device from the third virtual network group, so as to avoid the industrial device continuing to occupy the third virtual network group after it goes offline, which would affect the normal communication between the client terminal device and other devices.

[0092] Step 402: Based on each third SUPI in the third virtual network group modification request, query and obtain the third virtual LAN identifier corresponding to each third SUPI.

[0093] Step 403: Based on each third SUPI and third VLAN ID, forward the third VLAN group modification request to NEF so that NEF can remove each third SUPI from the third VLAN group corresponding to the third VLAN ID.

[0094] Upon receiving a modification request for the third virtual network group, the management server searches locally for the corresponding third virtual LAN identifier (VLAN ID_3) using each third SUPI (SUPI_3) as an index. If a matching record exists, a data record is generated.<SUPI_3,VLAN ID_3> This yields the third virtual local area network identifier (VLAN ID_3) corresponding to each third SUPI.

[0095] Furthermore, the network management server can send a third virtual network group modification request to NEF, requesting that the third VN group with the external identifier VLAN ID_3 be modified so that the third SUPI corresponding to each terminal module in the customer terminal device can be deleted from the third VN group.

[0096] Optionally, upon receiving a third virtual network group modification request, the NEF initiates a third subscription data modification request to the UDM, requesting the removal of each third SUPI from the third VN group. The UDM, based on this third subscription data modification request, can modify the subscription data, removing each third SUPI from the third VN group, and generate a third subscription data modification response to return to the NEF. The NEF, based on this response, can generate a third virtual network group modification response and return it to the network management server. The network management server then further returns this third virtual network group modification response to the client terminal device. Understandably, at this point, the client terminal device can know the current modification status of the third virtual network group based on this third virtual network group modification response, achieving synchronous updates of the modification results.

[0097] Using the embodiments of this application, if the customer terminal device does not receive data sent by the industrial equipment within a preset time period, the corresponding subscription data can be modified through the network management server to remove the third SUPI corresponding to each terminal module in the customer terminal device from the third VN group, thereby modifying the third VN group and preventing the third virtual network group from continuing to occupy after the industrial equipment goes offline, thus affecting the normal communication between the customer terminal device and other devices.

[0098] In an optional implementation, the client terminal device is configured to: if it receives a successful modification response or a successful creation response for the first virtual network group, start a preset timer to wait for data sent by the industrial device; if it receives data sent by the industrial device within a preset time period, reset the preset timer and start timing again; if it still does not receive data sent by the industrial device 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 explanation, after the client terminal device receives a successful modification response or a successful creation response for the third VN group from the network management server, it can create and start a timer locally. If data is received from any industrial device within a preset time period (e.g., group 1, 5 minutes, etc.), the preset timer is reset and starts counting down, i.e., it is cleared to zero and starts counting down, waiting to receive new data, and this process is repeated. If no data is received from the industrial device 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 be found in steps 501 and 502 below. Of course, if modifications are required, please refer to steps 101 and 102 above.

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

[0102] Figure 5 This is a flowchart illustrating another communication configuration method provided in an embodiment of this application. In optional implementations, such as... Figure 5 As shown, the above method also includes:

[0103] Step 501: Receive the fourth virtual LAN identifier creation request sent by the client terminal device based on the ARP response sent by the target industrial device.

[0104] 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-transmission and selective reception services, as issued by the management server, and the fourth virtual LAN identifier associated with the target industrial device. The client terminal device has multiple industrial devices mounted on it.

[0105] The network management server can pre-configure the target device address (e.g., IP address) and its associated fourth virtual LAN identifier (VLAN ID_4) of the target industrial devices that need to provide dual-transmit and selective-receive services.

[0106] Optionally, the client terminal device can be configured to read the fourth SUPI of each of its built-in terminal modules 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 LAN 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 it is connected to, and receive the ARP response sent by the target industrial device; based on the ARP response, it sends a fourth virtual LAN identifier creation request to the network management server through the UPF, requesting the creation of a fourth VN group in the UDM.

[0108] Step 502: Based on the fourth VLAN ID creation request, send a fourth subscription data modification request to NEF to create the fourth virtual network group corresponding to the fourth VLAN ID through NEF, and add each fourth SUP to the fourth virtual network group.

[0109] After receiving the request to create the fourth virtual LAN identifier, the network management server generates the following data record:<SUPI_4,VLAN ID_4> SUPI_4 includes the fourth SUPI identifier of each terminal module built into the customer terminal device, which is reported by the customer terminal device, and VLAN ID_4 is the fourth virtual LAN identifier.

[0110] Furthermore, based on the generated data records, the network management server sends a fourth subscription data modification request to the NEF, requesting modification of the subscription data in the UDM. Through modification, a fourth VN group with VLAN ID_4 as the external identifier is created, and each fourth SUPI is added to the fourth virtual network group.

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

[0112] Figure 6 This is a flowchart illustrating another communication configuration method provided in an embodiment of this application. In optional implementations, such as... Figure 6 As shown, before receiving the fourth Virtual LAN Identifier Creation Request sent by the client terminal device based on the ARP response sent by the target industrial equipment, the process further includes:

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

[0114] Step 602: Based on each fourth SUPI identifier, send the target device address of the target industrial device that needs to provide dual-transmit and selective-receive services and the fourth virtual LAN identifier associated with the target industrial device to the client terminal device, so that the client terminal device can send ARP requests to each industrial device it is connected to based on the target device address and receive ARP responses sent by the target industrial device.

[0115] The target industrial equipment that needs to provide dual-transmission and reception services can be one or more of the multiple industrial equipment mounted on the customer terminal equipment, without any limitation.

[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 (e.g., IP address) of the target industrial device that needs to provide dual-transmit selective reception service in the client terminal device and its associated fourth virtual LAN identifier (VLAN ID_4) to the client terminal device.

[0117] After receiving the IP address of the target industrial device, the client terminal device uses these IP addresses as the query target address and sends an ARP request to the connected industrial device through its local network port. After receiving the ARP request, the industrial device determines whether the query target address is its own address. If it is, 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 this application, targeted configuration can be achieved for target industrial equipment that provides dual-transmission and selective reception services, thereby improving the applicability and flexibility of the method of this application.

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

[0120] In some embodiments, in order to ensure that when the user permanent identifier (SUPI) of any terminal module in the client terminal device changes, it can be set to obtain the SUPI of each terminal module at 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. In this case, the relevant configuration can be performed according to the content of steps 101 to 103 above. The specific configuration method can be found in the relevant content mentioned above, and will not be repeated here.

[0121] In summary, using the embodiments of this application, the client terminal device detects locally connected industrial devices and, in conjunction with the dual-transmission selective reception configuration information of the industrial devices issued by the network management server, determines whether there are industrial devices locally connected that require dual-transmission selective reception guarantees. If so, the client terminal device modifies the corresponding subscription 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 locally connected industrial devices. If it detects that an industrial device requiring dual-transmission selective reception guarantees is offline, it modifies the corresponding UDM subscription data through the network management server to remove the SUPI corresponding to the terminal module from the corresponding VN group. Furthermore, the client terminal device can also continuously detect the SIM card information in its built-in terminal module. If there are changes, it modifies the corresponding UDM subscription data through the network management server to ensure that the terminal module that has changed still resides in the VN group.

[0122] Based on this application, by automatically configuring dedicated subscription data for different terminal modules within the same customer terminal device in the UDM, and assigning them to the same VN group, it is possible to ensure that different terminal modules within the same customer terminal device establish PDU session connections with the same UPF, enabling dual-transmit selective reception services. Compared with existing technologies, this avoids the problem of low configuration efficiency caused by manual configuration when there are many terminal modules to be configured, and avoids configuration errors. Furthermore, this application also supports situations where some terminal modules in the customer terminal device need to have their SIM cards changed, requiring corresponding changes to the subscription data in the UDM, which can achieve automated configuration, improve configuration efficiency, and ensure configuration effectiveness.

[0123] In an optional implementation, the above communication configuration method can be applied to a client terminal device, which includes multiple terminal modules supporting dual-transmit selective reception service. 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. The network management server then queries and obtains the first SUPI corresponding to the target terminal module based on the first virtual network group modification request. The first SUPI is the one that the target terminal module corresponds to before the update. Based on the second SUPI, the first SUPI, and the first virtual LAN identifier, the first virtual network group modification request is forwarded to NEF.

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

[0126] By applying the embodiments of this application, when a customer terminal device detects a change in the SIM card information in its built-in target terminal module, it can automatically modify the corresponding UDM subscription data through the network management server, 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, which can realize automated configuration, improve configuration efficiency, and avoid configuration errors.
