Description

Technical Field

[0002] In the fifth generation (5G) communication system, 5G local area network (5GLAN), also known as 5G virtual network (5GVN), is a service of 5G network defined by the third generation partnership project (3GPP), which is mainly used in home communication, corporate office, factory manufacturing, Internet of Vehicles, power grid transformation and public security organs. The 5GVN service can provide private communication of Internet protocol (IP) type or non-IP type (such as Ethernet type) for two or more terminals in a group. For example, the office equipment of employees in a department of an enterprise can form a group, and the office equipment in the group communicates with each other, while the office equipment outside the group cannot communicate with each other.

[0003] For the 5G LAN service, the 3rd generation partnership project (3GPP) proposed to support one-to-one and one-to-many communications of 5G LAN. Specifically, to support one-to-one and one-to-many communications of 5G LAN, the 3GPP network is required to support group-based unicast, multicast and broadcast; support the replication and distribution of multicast and broadcast messages; and support any terminal as a multicast source.

[0004] Currently, 3GPP 23.501 defines that a 5G VN is managed by only one Session Management Function (SMF) network element, which also manages one or more User Plane Function (UPF) network elements.

[0045] In addition, the network architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. Ordinary technicians in this field can know that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0046] like Figure 1As shown, the embodiment of the present application provides a service processing system 10, which includes: a capability open network element 101 and a first service management device 102. The capability open network element 101 and the first service management device 102 can communicate directly or through forwarding of other devices, which is not specifically limited in the embodiment of the present application.

[0047] In a specific implementation, the first service management device 102 may exist independently or be integrated into other network elements, such as a session management network element, a user data warehouse 104, or a user data management device 105, which is not limited in this application.

[0048] In a possible implementation, the capability opening network element 101 is used to receive a first message from an application function network element, the first message carries a terminal identifier and first network information of a first virtual network, the first network information includes a first virtual network identifier, and the first message is used to request that a terminal corresponding to the terminal identifier be added to a first virtual network corresponding to the first virtual network identifier; the capability opening network element 101 is used to determine a first service management device 102 serving the first virtual network according to the first network information; the capability opening network element 101 is used to send a second message to the first service management device 102, the second message carries the terminal identifier and the first network information, and the second message is used to request that the terminal be added to the first virtual network so that the correspondence between the terminal identifier and the first network information is saved; the first service management device 102 is used to receive the second message. Through this solution, it can be realized that in a network with multiple service management devices, the capability opening network element 101 can also address the first service management device serving the terminal, thereby adding the terminal to the virtual network.

[0049] The first virtual network identifier may also be referred to as a first virtual network group identifier; a virtual network may sometimes also be referred to as a virtual network group, or a virtual group, etc., and the names are not limited here.

[0050] In another possible implementation, the system 10 further includes a network storage function network element 103. The capability opening network element 101 is used to send the first network information to the network storage function network element 103; the network storage function network element 103 is used to send the first service management device identification information corresponding to the first network information to the capability opening network element 101 according to the correspondence between the stored first network information and the first service management device identification. In this way, the capability opening network element 101 addresses the first service management device serving the terminal.

[0051] In another possible implementation, the first virtual network identifier includes the identification information of the first service management device, and the capability open network element 101 obtains the identification information of the first service management device from the first virtual network identifier. Through this solution, the capability open network element 101 can address the first service management device serving the terminal. In this way, when allocating the first virtual network identifier, the first service management device 102 also embeds the identification of the first service management device into the first virtual network identifier. In this way, the first virtual network identifier includes the identification of the first service management device. In a specific implementation, a certain coding rule can be used to allocate the first virtual network identifier, and then the coding rule is pre-configured in the capability open network element 101, or the first service management device 102 sends the coding rule to the capability open network element 101. Then, the capability open network element 101 obtains the identification of the first service management device from the first virtual network identifier according to the coding rule.

[0052] There are multiple encoding methods for encoding rules, such as: defining the first 8 bytes of the first virtual network identifier as the device identifier of the first business management device, and the third party obtains the device identifier of the first business management device through the first virtual network identifier, and then can find the business management device based on the device identifier of the first business management device. The device identifier here can be an Internet Protocol (IP) address or a fully qualified domain name (FQDN). There is no limitation here.

[0053] In another possible implementation, the system 10 further includes a user data warehouse 104. The first service management device 102 is used to send the first network information and the terminal identifier to the user data warehouse 104; the user data warehouse 104 is used to store the correspondence between the first network information and the terminal identifier.

[0054] In a specific implementation, if the first service management device 102 and the user data warehouse 104 are integrated together, or jointly configured, the first service management device 102 stores the corresponding relationship between the first network information and the terminal identifier.

[0055] In another possible implementation, the system 10 further includes a user data management device 105. The first service management device 102 is configured to send a third message for modifying the subscription to the user data management device 105, wherein the third message carries the terminal identifier and the first virtual network identifier; and the user data management device 105 is configured to add the first virtual network identifier to the subscription data of the terminal corresponding to the terminal identifier.

[0056] In a specific implementation, if the first service management device 102 and the user data management device 105 are integrated (or co-installed) together, the first service management device 102 does not need to send the third message. Instead, the first service management device 102 adds the first virtual network identifier to the contract data of the terminal corresponding to the terminal identifier.

[0057] like Figure 2 As shown, the embodiment of the present application provides another service processing system 20, which includes: a session management network element 201 and a first service management device 202. The session management network element 201 and the first service management device 202 can communicate directly or through forwarding of other devices, which is not specifically limited in the embodiment of the present application.

[0058] In a possible implementation, the session management network element 201 is used to receive a session establishment request message from a terminal, the session establishment request message carries the terminal identifier of the terminal; the session management network element 201 is used to obtain the first virtual network identifier of the first virtual network where the terminal is located from the user data management device; determine the first service management device serving the first virtual network according to the first virtual network identifier; send a notification message to the first service management device 202, the notification message carries the terminal identifier and the first virtual network identifier, and is used to notify the first service management device that the terminal joins the first virtual network. Through this solution, it can be achieved that in a network with multiple GSMFs, the session management network element 201 can also address the first service management device serving the terminal, so as to notify the first service management device 202 of the terminal going online message.

[0059] In another possible implementation, the system 20 further includes a network storage function network element 203. The session management network element 201 is used to send first network information of the first virtual network to the network storage function network element 203, wherein the first network information includes a first virtual network identifier; the network storage function network element 103 is used to send the first service management device identifier information corresponding to the first network information to the session management network element 201 according to the correspondence between the stored first network information and the first service management device identifier. In this way, the session management network element 201 addresses the first service management device 202 serving the terminal.

[0060] In another possible implementation, the first virtual network identifier includes the identification information of the first service management device, and the session management network element 201 is used to obtain the identification information of the first service management device from the first virtual network identifier. Through this solution, the session management network element 201 can address the first service management device serving the terminal. The coding rules for allocating the first virtual network identifier can be found in Figure 1 Description in .

[0061] In a specific implementation, in an embodiment of the present application, the first network information may include, in addition to the first virtual network identifier, a first data network name (Data network name, DNN) and first single-network slice selection assistance information (Single-Network Slice Selection Assistance Information, S-NSSAI).

[0062] The specific implementation of the above solution will be described in detail in the subsequent method implementation examples and will not be repeated here.

[0063] Figure 1 and Figure 2 The system shown can be used in Figure 3 The 5G network architecture shown can, of course, also be used in future network architectures, such as 6G network architecture, etc., and this application does not limit it.

[0064] Below Figure 3 The 5G network architecture shown in FIG. 1 is used as an example for explanation. Among them, the capability exposure network element 101 corresponds to the network exposure function (NEF) network element in 5G, the network storage function network element 103 corresponds to the network storage function (NRF) network element in 5G, the user data warehouse 104 corresponds to the unified data repository (UDR) network element in 5G, the session management network element corresponds to the session management function (SMF) network element in 5G, the user data management device corresponds to the unified data management (UDM) network element in 5G, and the application function network element corresponds to the application function (AF) network element in 5G.

[0065] like Figure 3 As shown, the 5G network architecture may also include a user plane function (UPF) network element, which is not specifically limited in the embodiments of the present application.

[0066] Among them, the terminal equipment communicates with the AMF network element through the next generation network (next generation, N) 1 interface (referred to as N1), the radio access network (RAN) equipment communicates with the AMF network element through the N2 interface (referred to as N2), the RAN equipment communicates with the UPF network element through the N3 interface (referred to as N3), the UPF network element communicates with the DN through the N6 interface (referred to as N6), the AMF network element communicates with the SMF network element through the N11 interface (referred to as N11), the AMF network element communicates with the UDM network element through the N8 interface (referred to as N8), the SMF network element communicates with the UPF network element through the N4 interface (referred to as N4), the SMF network element communicates with the UDM network element through the N10 interface (referred to as N10), and the UPF network elements communicate with the UPF network elements through the N9 interface (referred to as N9).

[0067] In addition, it should be noted that Figure 4 The AMF network element, NRF network element, NEF network element, AF network element, SMF network element, or UDM network element in the 5G network architecture shown can also interact using service-oriented interfaces. Figure 4 As shown, the service interface provided by the AMF network element to the outside can be Namf; the service interface provided by the NRF network element to the outside can be Nnrf; the service interface provided by the NEF network element to the outside can be Nnef; the service interface provided by the AF network element to the outside can be Naf; the service interface provided by the SMF network element to the outside can be Nsmf; the service interface provided by the UDM network element to the outside can be Nudm. For related descriptions, please refer to the 5G system architecture in the 23.501 standard, which will not be repeated here.

[0068] Among them, the service management device corresponds to the GSMF network element in 5G, and the GSMF network element can also be called a 5GVN controller (5GVNcontroller), and the name is not limited. In this application, the GSMF network element is used as an example for explanation. GSMF can be deployed separately, or it can be integrated or co-located in a UDR network element, a UDM network element, or an SMF network element, and of course it is not limited to these network elements. Figure 3 and Figure 4 The above takes the deployment of GSMF network elements alone as an example, and other scenarios are not shown. Figure 4 In the example, the service interface Ngsmf provided by GSMF is taken as an example. Of course, the name of this interface can also be other names in the future, and there is no limitation here.

[0069] Among them, the virtual network identifier in 5G can be used to represent the 5GVN identifier, referred to as the 5GVN identifier (Identity, ID), and sometimes also called the 5G Identifier. The 5GVN ID can be used to identify a 5GVN.

[0070] Among them, the GSMF network element is responsible for the global management of the information of the entire 5GVN, including the SMF where each member (i.e. each terminal device in the network) is located, and / or is responsible for the global management of the routing information of each member of a 5GVN, such as the information of the UPF where each member is located. The UDR network element here is used to save the configuration information of the 5GVN, such as 5GVN member information, etc.; it can also save the 5GVN content defined by a third party through the NEF network element. The GSMF network element can call the 5GVN content stored by the UDR network element.

[0071] When the GSMF network element and the UDR network element are co-located, the UDR network element stores the routing information of each member of the 5GVN, and the GSMF network element is responsible for external interaction; the NEF network element is open to third parties to define the 5GVN and add or delete members for the 5GVN. The UDM network element is used to sign the 5GVN identity of the member.

[0072] In actual networking, operators can deploy multiple 5GVN networks. A 5GVN network is sometimes also called a 5GVN instance. A GSMF network element can manage or serve two or more 5GVN instances. A 5GVN instance is served by a GSMF network element.

[0073] A 5GVN instance can have an SMF network element or instance, which manages a single or multiple UPF network elements at the same time and configures corresponding forwarding rules on the UPF network element. Taking the one-to-one communication between UE1 and UE2 as an example, if UE1 and UE2 are served by the same UPF network element, such as UPF1 network element, the transmission is carried out through the UPF local switch. Taking the one-to-one communication between UE2 and UE3 as an example, if UE2 and UE3 are served by different UPF network elements, such as UE2 is served by UPF1 network element and UE3 is served by UPF2 network element, then the transmission between UE1 and UE3 needs to be carried out through the tunnel between UPF1 network element and UPF2 network element. However, the service area of ​​the SMF network element is limited. If the coverage of 5GVN is large, for example, a company has branches in Beijing and Shenzhen, both branches belong to this 5GVN, the Beijing branch is managed by the SMF1 network element, and the Shenzhen branch is managed by the SMF2 network element. In order to simplify the processing of the control plane, the SMF1 network element and the SMF2 network element can be managed by one GSMF network element.

[0089] The following will be combined Figures 1 to 5 The business processing method provided in the embodiment of the present application is specifically described.

[0090] Figure 6 A flowchart of a business processing method is provided.

[0091] S601: The AF network element sends a first message to the NEF network element, and the NEF network element receives the first message.

[0092] Specifically, the first message carries the first network identifier and terminal identifier of 5GVN. Here, the terminal identifier takes the absolute identifier (Generic Public Subscription Identifier, GPSI) of UE as an example. The first network identifier of 5GVN can be identified by 5GVN ID; it can also be identified by 5GVN ID, DNN and S-NSSAI together.

[0093] Among them, the first message is used to request that the terminal UE1 corresponding to GPSI be added to 5GVN1 (corresponding to the first virtual network) corresponding to the 5GVN ID, that is, to add a new member UE1 to 5GVN1.

[0094] S603, the NEF network element sends the first network identifier of the 5GVN to the NRF network element, and the NRF network element receives the 5GVN ID.

[0095] S605, the NRF network element sends the GSMF1 identifier corresponding to the first network identifier of 5GVN stored in itself to the NEF, and the NEF network element receives the GSMF1 identifier.

[0096] In the embodiment of the present application, a 5GVN is taken as an example by a GSMF network element. However, in actual implementation, if 5GVN1 is served by multiple GSMF network elements, the NRF network element may return the address set or FQDN of these multiple GSMF network elements. If the NRF network element returns a GSMF address set, the NEF selects a GSMF address randomly or according to a certain strategy; if the NRF network element returns an FQDN, the NEF network element then finds an IP address list from the domain name server (DNS) according to the FQDN, and the NEF network element finds an address from the IP address list as the target instance of the GSMF.

[0097] S607, the NEF network element sends a second message to GSMF1 according to the identifier of GSMF1, and sends the first network identifier and the terminal identifier received in S601 to the GSMF1 network element. The GSMF1 network element receives the second message. The second message is used to request that UE1 be added to 5GVN1.

[0098] S609, the GSMF1 network element sends the first network identifier and the terminal identifier to the UDR network element, and the UDR network element receives the first network identifier and the terminal identifier.

[0099] Optionally, the UDR network element stores the correspondence between the terminal identifier and the first network information, so that UE1 can use it when performing services in the 5GCN1 network later.

[0100] Optionally, if the GSMF1 network element and the UDR network element are jointly provided, S609 may not be executed, and the GSMF1 saves the correspondence between the terminal identifier and the first network information.

[0101] In actual implementation, step S611 may also be included.

[0102] S611, the GSMF1 network element sends a third message for modifying the subscription to the UDM network element, wherein the third message carries the GPSI and the first virtual network identifier of UE1, and the UDM network element receives the GPSI and the first virtual network identifier of UE1.

[0103] Optionally, the UDM network element adds the first virtual network identifier to the subscription data of UE1 corresponding to the GPSI.

[0104] There is no time limit for the execution of S609 and S611. S609 can be executed first, then S611; or S611 can be executed first, then S609.

[0105] As an implementation method, the correspondence between the first network identifier of 5GVN and the GSMF identifier stored on the NRF network element can be implemented by S600a and S600b described below. Of course, other methods can also be used to implement it. For example, the above correspondence can be saved on the NRF network element by configuration. This application is not limited.

[0106] S600a, the GSMF1 network element sends a registration message to the NRF network element, and the NRF network element receives the registration message.

[0107] Specifically, the registration message carries the identifier of GSMF1 and the network information of at least one virtual network served by GSMF1. The network information of each virtual network in the network information of the at least one virtual network includes the identifier of the virtual network; or, the network information of each virtual network includes the identifier of the virtual network, DNN and S-NSSAI. The at least one virtual network includes 5GVN1.

[0108] S600b: The NRF network element saves the correspondence between the identifier of GSMF1 and the network information of at least one virtual network.

[0109] Like GSMF1, other GSMF network elements can also send their own identification and network information of at least one virtual network they serve to the NRF network element by sending a registration message. The NRF network element maintains a list of these GSMF network elements.

[0110] For example, there are four virtual networks 5GVN1, 5GVN2, 5GVN3 and 5GVN4. GSMF1 serves 5GVN1. GSMF2 serves 5GVN2, 5GVN3 and 5GVN4. The network identifier of 5GVN1 is 5GVN1 ID. The network identifier of 5GVN2 is 5GVN2 ID+DNN1+S-NSSAI1; optionally, the network identifier of 5GVN2 can also be 5GVN2 ID+ DNN1+S-NSSAI1+group number. The network identifier of 5GVN3 is 5GVN3 ID+ DNN1+S-NSSAI1; optionally, the network identifier of 5GVN2 can also be 5GVN3ID+ DNN1+S-NSSAI1+group number. The network identifier of 5GVN4 is 5GVN3 ID+ DNN2+S-NSSAI2; optionally, the network identifier of 5GVN4 can also be 5GVN3 ID+ DNN2+S-NSSAI2+group number. The information stored in NRF is shown in Table 1 below.

[0113] Based on the service processing method provided in this embodiment, it is possible to accurately address the GSMF network element serving the terminal in a network with multiple GSMF network elements, thereby adding the terminal to the virtual network 5GVN1.

[0114] The actions of the NEF network element or the GSMF1 network element or the NRF network element in the above steps S601-S611 and S600a-S600b can be performed by Figure 5 The processor 501 in the communication device 500 shown calls the application code stored in the memory 503 for execution, and this embodiment does not impose any limitation on this.

[0116] S701, same as S601.

[0117] S703, the NEF network element obtains the identification information of GSMF1 from the 5GVN ID.

[0118] specific, same as Figure 1 As described in the illustrated embodiment, the GSMF1 identifier is embedded in the 5GVN ID. Therefore, the NEF network element can obtain the GSMF1 identifier information from the 5GVN ID according to the encoding rules.

[0119] S705-S709, same as S607-S611.

[0120] Based on the service processing method provided in this embodiment, it is possible to accurately address the GSMF serving the terminal in a network with multiple GSMFs, thereby adding the terminal to the virtual network 5GVN1.

[0121] The actions of the NEF network element or the GSMF1 network element in the above steps S701-709 can be performed by Figure 5 The processor 501 in the communication device 500 shown calls the application code stored in the memory 503 for execution, and this embodiment does not impose any limitation on this.

[0122] Figure 8 A flowchart of another business processing method is provided.

[0123] S801, UE sends a first message to an SMF network element. The SMF network element receives the first message.

[0124] The first message carries the terminal identifier GPSI, and may also carry DNN and S-BSSAI. The first message is used to request the establishment of a protocol data unit (PDU) session.

[0125] S803, the SMF network element requests the terminal's contract data from the UDM network element, and the UDM network element sends the terminal's contract data to the SMF network element.

[0126] Among them, the subscription data includes the group identifier of 5GVN1 where the terminal is located, that is, 5GVN ID.

[0127] S805, the SMF network element controls the establishment of an N4 session with the UPF network element. The specific process refers to the standard process and will not be described in detail here.

[0128] S807, the SMF network element sends the first network identifier of 5GVN to the NRF network element, and the NRF network element receives the 5GVN ID.

[0129] S809, the NRF network element sends the GSMF1 identifier corresponding to the first network identifier of 5GVN stored in itself to the SMF network element, and the SMF network element receives the GSMF1 identifier.

[0130] S811, the SMF network element sends a notification message to the GSMF1 network element, and the GSMF1 network element receives the notification message.

[0131] The notification message carries GPSI and 5GVN ID, and is used to notify GSMF1 that a new terminal, that is, a terminal identified by GPSI, has joined the 5GVN1 network. The notification message may also carry routing information of the UPF to which the terminal accesses, such as the port or address of the UPF network element.

[0132] Optionally, S813 may also be included. In S813, the GSMF1 network element sends a notification message to other SMF network elements to notify other SMF network elements that a new terminal has joined.

[0133] As an implementation method, the correspondence between the first network identifier of 5GVN and the GSMF identifier stored on the NRF network element can be implemented through steps S800a and S800b. Of course, other methods can also be used to implement it. For example, the above correspondence can be saved on the NRF network element by configuration. This application is not limited.

[0134] The specific implementation of S800a and S800b is the same as S600a and S600b.

[0135] Based on the service processing method provided in this embodiment, it is possible to accurately address the GSMF network element serving the terminal in a network with multiple GSMFs, thereby realizing member online services.

[0136] The actions of the SMF network element or the NRF network element in the above steps S801-S813 and S800a-S800b can be performed by Figure 5The processor 501 in the communication device 500 shown calls the application code stored in the memory 503 for execution, and this embodiment does not impose any limitation on this.

[0137] Fig. 9 A flowchart of another business processing method is provided.

[0138] S901-S905, same as S801-S805.

[0139] S907, SMF obtains the identification information of GSMF1 from 5GVN ID.

[0140] specific, same as Figure 1 As described in the illustrated embodiment, the identification of GSMF1 is embedded in the 5GVN ID. Therefore, the SMF can obtain the identification information of GSMF1 from the 5GVN ID according to the encoding rules.

[0141] S909-S911, same as S811-S813.

[0142] Based on the service processing method provided in this embodiment, it is possible to accurately address the GSMF network element serving the terminal in a network with multiple GSMFs, thereby realizing member online services.

[0143] Among them, the actions of the SMF network element in the above steps S901-S911 can be Figure 5 The processor 501 in the communication device 500 shown calls the application code stored in the memory 503 for execution, and this embodiment does not impose any limitation on this.

[0144] As a way to achieve this, Figure 6 , Figure 7 , Figure 8 or Fig. 9 Based on the embodiment shown, a process of defining a new 5GVN may also be included. Of course, the process of defining a new 5GVN may also exist independently. Fig.10 To explain.

[0145] S1001, the AF network element sends a request message to the NEF network element, and the NEF network element receives the request message. The request message is used to add a new virtual network 5GVN1, which can also be said to be a request message for adding a new virtual network. The request message carries the DNN and S-NSSAI information corresponding to the newly added 5GVN1, and optionally, can also carry a member list.

[0146] S1003, the NEF network element obtains GSMF information from the NRF network element.

[0147] Specifically, after receiving the DNN and S-NSSAI, the NEF network element cannot know which GSMF instance serves the 5GVN1 based on the DNN, so the NEF network element sends the DNN and S-NSSAI information to the NRF network element, and the NRF network element receives the DNN and S-NSSAI message. The NRF network element sends a list of all GSMF instances corresponding to the DNN+S-NSSAI to the NEF. Among them, the GSMF instance list includes GSMF1. Then, the NEF network element randomly selects, or selects the GSMF1 network element according to a certain strategy as the GSMF network element serving 5GVN1.

[0148] In a specific implementation, the NRF network element may also select GSMF1 from a list of all GSMF instances corresponding to DNN+S-NSSAI, and then send the identification information of GSMF1 to the NEF network element.

[0149] S1005, the NEF network element sends the DNN and S-NSSAI to the GSMF1 network element, and the GSMF1 network element receives the DNN and S-NSSAI.

[0150] S1007, GSMF1 network element allocates 5GVN1 ID according to DNN and S-NSSAI.

[0151] As an implementation method, when GSMF1 allocates 5GVN1 ID, the GSMF1 identifier can be embedded into 5GVN1ID, so that GSMF1 can be found according to 5GVN1 ID later. Optionally, it can be embedded according to certain encoding rules.

[0152] S1009, the GSMF1 network element sends the 5GVN1 ID to the AF network element through the NEF.

[0153] Specifically, the GSMF1 network element sends the 5GVN1 ID to the NEF network element, and the NEF network element sends a response message to the AF network element. After the AF network element receives the 5GVN1 ID, the AF network element will use the ID to interact with the same 5GVN in the future.

[0154] Optionally, NEF may forward the content sent by the GSMF1 network element to the AF network element; or convert the content sent by the GSMF1 network element into a message format and send it to the AF network element; or send the 5GVN1 ID therein to the AF network element in these two ways.

[0155] As an implementation method, the virtual network identifier received by the NEF network element from the GSMF1 network element is different from the virtual network identifier sent to the AF network element, but these two identifiers can identify the same virtual network. Optionally, the correspondence between the two virtual network identifiers can be saved in the NEF network element. For example: the two virtual network identifiers are identifier A and identifier B, both of which are used to identify virtual network 1. Among them, the NEF network element receives identifier A from the GSMF1 network element and sends identifier B to the AF. When the AF network element subsequently uses identifier B to perform services, the NEF network element receives identifier B sent by the AF network element, and obtains identifier A corresponding to identifier B based on the saved correspondence between identifier A and identifier B. Then the NEF network element uses identifier A to interact with the GSMF network elements, NRF network elements or UDR network elements in the network. If this is the implementation method, then Figure 6 or Figure 7 In the example, the 5GVN identifier carried in the message sent by the AF network element to the NEF network element will be converted into another form of the 5GVN identifier when passing through the NEF, and then the converted 5GVN identifier will be used to interact with network elements such as the NRF. The details will not be described in detail here.

[0156] Optional, Fig.10 The illustrated embodiment may further include S1101, where the GSMF1 network element sends DNN, S-NSSAI and 5GVN1 ID to the UDR network element, and the UDR network element receives these three parameters. Optionally, the UDR network element may also save these three parameters.

[0157] There is no order of precedence for S1009 and S1011. S1009 may be executed first, and then S1011; or S1011 may be executed first, and then S1009.

[0158] Based on the service processing method provided in this embodiment, a new 5GVN can be defined. By sending the new 5GVN ID to the AF, communication between terminals in the network can be implemented later through the 5GVN.

[0159] The actions of the NEF network element or the GSMF1 network element in the above steps S1001-S1011 can be performed by Figure 5 The processor 501 in the communication device 500 shown calls the application code stored in the memory 503 for execution, and this embodiment does not impose any limitation on this.

[0160] It can be understood that, in each of the above embodiments, the methods and / or steps implemented by the capability openness network element can also be implemented by components (such as chips or circuits) that can be used for the capability openness network element; the methods and / or steps implemented by the session management network element can also be implemented by components (such as chips or circuits) that can be used for the session management network element.

[0161] The above mainly introduces the scheme provided by the embodiment of the present application from the perspective of interaction between various network elements. Accordingly, the embodiment of the present application also provides a communication device, which can be the capability open network element in the above method embodiment, or a device including the above capability open network element, or a component that can be used for the capability open network element; or, the communication device can be the session management network element in the above method embodiment, or a device including the above session management network element, or a component that can be used for the session management network element. It can be understood that in order to implement the above functions, the communication device includes a hardware structure and / or software module corresponding to each function. Those skilled in the art should easily realize that, in combination with the units and algorithm steps of each example described in the embodiments disclosed in this article, the present application can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of the present application.

[0162] For example, taking the communication device as the capability opening network element in the above method embodiment as an example, Fig.11 The schematic diagram of the structure of a capability open network element 110 is shown. The capability open network element 110 includes a transceiver module 1101 and a processing module 1102. The transceiver module 1101, which may also be called a transceiver unit, is used to implement the transceiver function, and may be a transceiver circuit, a transceiver, a transceiver or a communication interface. The following is an explanation.

[0163] Among them, the transceiver module 1101 is used to receive a first message from an application function network element, the first message carries a terminal identifier and first network information of a first virtual network, wherein the first network information includes a first virtual network identifier, and the first message is used to request that the terminal corresponding to the terminal identifier be added to the first virtual network corresponding to the first virtual network identifier; the processing module 1102 is used to determine a first service management device serving the first virtual network based on the first network information; the transceiver module 1101 is also used to send a second message to the first service management device, wherein the second message carries the terminal identifier and the first network information, and the second message is used to request that the terminal be added to the first virtual network so that the correspondence between the terminal identifier and the first network information is saved.

[0164] In one implementation, the processing module 1102 is specifically configured to send the first network information to a network storage function network element; and receive the first service management device identification information corresponding to the first network information from the network storage function network element.

[0165] In another implementation, the processing module 1102 is specifically configured to obtain identification information of the first service management device from the first virtual network identifier, wherein the first virtual network identifier includes identification information of the first service management device.

[0166] In another implementation, the first network information also includes the first data network name and the first single network slice selection auxiliary information. Then the transceiver module 1101 is used to receive a new virtual network request message from the application function network element, and the new virtual network request message carries the first data network name and the first single network slice selection auxiliary information; send the first data network name and the first single network slice selection auxiliary information to the network storage function network element; receive information from at least one service management device corresponding to the first data network name and the first single network slice selection auxiliary information sent by the network storage function network element, and the at least one service management device includes the first service management device; send the first data network name and the first single network slice selection auxiliary information to the first service management device; receive the first virtual network identifier corresponding to the first data network name and the first single network slice selection auxiliary information assigned by the first service management device; send a new virtual network response message carrying the first virtual network identifier to the application function network element.

[0167] In this embodiment, the capability open network element 110 is presented in the form of dividing various functional modules in an integrated manner. The "module" here may refer to a specific ASIC, a circuit, a processor and a memory that executes one or more software or firmware programs, an integrated logic circuit, and / or other devices that can provide the above functions. In a simple embodiment, those skilled in the art can imagine that the capability open network element 110 can be used Figure 5 The form of a communication device 500 is shown.

[0168] for example, Figure 5 The processor 501 in the communication device 500 shown can call the computer executable instructions stored in the memory 503 to enable the communication device 500 to execute the service processing method in the above method embodiment.

[0169] Specifically, Fig.11 The functions / implementation processes of the transceiver module 1101 and the processing module 1102 can be Figure 5 The processor 501 in the communication device 500 shown calls the computer executable instructions stored in the memory 503 to implement. Or, Fig.11 The function / implementation process of the processing module 1002 in Figure 5The processor 501 in the communication device 500 shown calls the computer execution instructions stored in the memory 503 to implement, Fig.11 The function / implementation process of the transceiver module 1101 can be Figure 5 The communication interface 504 in the communication device 500 shown in FIG.

[0170] Since the capability opening network element 110 provided in this embodiment can execute the above service processing method, the technical effects that can be obtained can refer to the above method embodiment, which will not be described in detail here.

[0171] Or, for example, taking the communication device as the session management network element in the above method embodiment as an example, Fig.12 The diagram shows a structure of a session management network element 120. The session management network element 120 includes a transceiver module 1201 and a processing module 1202. The transceiver module 1201, which may also be called a transceiver unit, is used to implement a transceiver function, and may be, for example, a transceiver circuit, a transceiver, a transceiver or a communication interface.
