As described above, the present disclosure proposes a method and system for 6G network subnet interconnection, aiming at the requirement of user-centric subnet interconnection of 6G network. By introducing a 6G subnet attachment service node, a 6G subnet registration service node, a subnet module of a user database, an edge gateway and the like, a 6G network system architecture supporting multi-subnet access is formed. And a method and a flow for user subnet registration and inter-subnet routing are provided based on the architecture.
The 6G user identification based on the subnet is routed, so that the problems of insufficient number and service type perception can be effectively solved, the user experience is improved, and the operation management difficulty of the network is reduced. For example, the technical solution of the present disclosure may be implemented by the following embodiments.
Fig. 1 illustrates a flow chart of some embodiments of a subnet interconnection method of the present disclosure.
As shown in fig. 1, in step 110, a first edge gateway of a 6G subnet initiates a registration request to a registration service node. The registration request includes a gateway identification of the first edge gateway and an IP (Internet Protocol, network protocol) address.
In some embodiments, the first edge gateway initiates an attach request to the attachment service node before the first edge gateway registers. The attach request includes a gateway identification of the first edge gateway. And the attaching service node authenticates and authenticates the first edge gateway according to the attaching request.
For example, the attachment service node requests authentication information of the first edge gateway from the 6G user database; and the attachment service node authenticates and authenticates the first edge gateway according to the authentication information returned by the user database.
In some embodiments, the 6G edge gateway first receives a configuration template issued by the 6G subnet-service provisioning node. The configuration template contains user ID, edge gateway identification, registration authentication information, attachment and registration service node address, etc. The subnet registration module of the edge gateway initiates an attach request to the 6G subnet attachment service node using the configuration template. The request information contains the edge gateway identification.
For example, the 6G subnet attachment service node requests authentication information of the edge gateway from the 6G user database; the subnet module in the 6G user database returns authentication information; the 6G subnet attachment service node completes authentication according to the signed authentication requirement, and returns attachment response information including the edge gateway identification and the IP address to the registration gateway.
In some embodiments, in the case that the first edge gateway passes the authentication, the first edge gateway receives the attachment response information returned by the attachment service node. The attachment response information includes a gateway identification and an IP address of the first edge gateway.
For example, the subnet registration module of the edge gateway initiates a registration request to the 6G subnet registration service node, carrying the edge gateway identification and the IP address.
In step 120, the registration service node requests service subscription information of the first edge gateway according to the registration request.
In some embodiments, the registration service node requests service subscription information of the first edge gateway from the 6G user database.
For example, the registration service node of the 6G subnet requests edge gateway service subscription information from the 6G user database; and the subnet module of the 6G user database responds to the service subscription information.
In step 130, in the case that a response to the service subscription information is received, the registration service node updates the state of the first edge gateway to registered.
In some embodiments, in the case of receiving a response of the service subscription information returned by the user database, the registration service node will initiate an update request to the user database, and update the state of the first edge gateway in the user database to registered.
For example, the 6G subnet registration service node informs the edge gateway that registration was successful; the 6G subnet registration service node initiates a request to the 6G user database, updates the gateway state to registered, and associates an IP address; the subnet module of the 6G user database returns an update success response.
In step 140, the first edge gateway and other edge gateways implement subnet interconnection according to the registration information of the first edge gateway.
In some embodiments, the registration service node broadcasts registration information of the first edge gateway to at least one second edge gateway. The registration information includes a gateway identification and an IP address of the first edge gateway. The second edge gateway routes according to the registration information.
For example, the second edge gateway stores registration information and routes according to the registration information.
In some embodiments, the 6G subnet registration service node broadcasts the correspondence of the edge gateway identification and the IP address of the registration gateway to other edge gateways; other edge gateways store broadcast information; the other edge gateway returns a broadcast success response.
In some embodiments, the second edge gateway forwards the service connection request of the subnet-interconnected originating terminal to the first edge gateway. The service connection request includes a gateway identification of the first edge gateway.
For example, the 6G terminal 1 (corresponding to an originating terminal) initiates a service connection request for a specific service (such as voice, message, service control, etc.) to the edge gateway 1 (corresponding to a second edge gateway). The request information contains the destination edge gateway identification, namely edge gateway 2 identification.
In some embodiments, the first edge gateway forwards the service connection request to the destination terminal of the subnet interconnection. And the first edge gateway sends a request success response returned by the destination terminal to the initiating terminal through the second edge gateway so as to enable the initiating terminal to carry out service connection with the destination terminal.
For example, the first edge gateway selects the destination terminal according to the service mapping table and the policy.
For example, the second edge gateway forwards the service connection request of the subnet-interconnected initiator terminal to the first edge gateway. The service connection request includes a gateway identification of the first edge gateway. And the first edge gateway forwards the service connection request to the destination terminal interconnected with the sub-network. And the first edge gateway sends a request success response returned by the destination terminal to the initiating terminal through the second edge gateway so as to enable the initiating terminal to carry out service connection with the destination terminal.
In some embodiments, edge gateway 1's subnetwork routing module forwards the request to edge gateway 2 (corresponding to the first edge gateway). The request information contains the edge gateway 2 identity. The edge gateway 2 selects a terminal 2 (corresponding to the destination terminal) according to the service mapping table and the policy, and forwards the connection request to the 6G terminal 2.
The 6G terminal 2 returns a request success response. Edge gateway 2 returns a request success response to edge gateway 1. The subnet route module of the edge gateway 1 returns a successful response to the 6G terminal 1. And P2P service transfer is established between the user terminal 1 and the user terminal 2.
In the above embodiment, the subnet registration process based on the edge gateway identifier is implemented through interaction among the newly added edge gateway, the 6G subnet attachment service node, the 6G subnet registration service node and the subnet module of the 6G user database. Furthermore, a brand new routing mechanism based on the edge gateway identification is realized through broadcasting of registration information.
Therefore, the 6G terminals are interconnected through the user sub-network, and route is carried out based on the edge gateway identification, so that a large number of terminal access requirements can be met. The 6G network core node only provides the functions of edge gateway attachment, registration, routing information broadcasting, subnet data management and the like, and sinks the functions of terminal attachment, authentication, P2P service control, routing and the like to the edge gateway, thereby improving network efficiency.
Fig. 2 illustrates a schematic diagram of some embodiments of a subnet interconnection system of the present disclosure.
As shown in fig. 2, the 6G user subnetworks include personal subnetworks, home subnetworks, mobile subnetworks, enterprise subnetworks, and the like, each having edge gateways.
The service provisioning node of the 6G subnetwork supports self-service provisioning and management of the subscriber subnetwork.
The attachment service node of the 6G sub-network provides network access service for the edge gateway of the user sub-network, including authentication, IP address allocation and the like.
For example, the attachment service node of the 6G subnetwork supports the following functions: receiving an attachment request of an edge gateway, requesting subscription authentication information from a 6G user database, completing authentication according to the subscription authentication requirement, and returning attachment response information to a registration gateway; an IP address is assigned to the registration gateway.
The registration service node of the 6G sub-network provides a sub-network registration service for the attached edge gateway and provides 6G sub-network services such as registration status, routing information broadcast and the like.
For example, the registration service node of the 6G subnet supports the following functions: receiving a registration request of an edge gateway, requesting service subscription information from a 6G user database, completing authentication according to the subscription authentication information, and returning registration success response information to the registration gateway; initiating an update request to a 6G user database, updating the registration gateway state and associating the IP address; and broadcasting the corresponding relation between the edge gateway identification and the IP address of the registered gateway to other edge gateways.
The subnet module in the 6G user database stores the registration information of the user subnet, including the edge gateway identification, the identity of the user, the service information and the like.
For example, a subnet module in a 6G user database supports the following functions: storing registration information of a user subnet, including an edge gateway identifier, the identity of a user, service information and the like; and responding to authentication requests of the 6G subnet registration service node and the 6G subnet attachment service node.
The edge gateway completes the access authentication of the sub-network terminal, and realizes the service control and routing in and among the sub-networks.
For example, the subnet registration module of the edge gateway supports the following functions: initiating an attachment request to a 6G subnet attachment service node; a registration request is initiated to a 6G subnet registration service node.
For example, the edge gateway subnet routing module supports the following functions: forwarding the terminal specific service connection request to a designated edge gateway; after receiving the appointed service connection request, selecting a terminal according to a service mapping table and a strategy; forwarding the service connection request to the designated terminal.
