Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a service-oriented interaction method, device, user plane service and network service. Background Art

[0002] The 5G core network adopts a service-oriented architecture. NF (Network Function) completes service registration, update, and deregistration through NFR (Network Function Registry function), and NFs are called through service-oriented interfaces. Service-oriented design brings many advantages to the 5G core network, such as independent upgrade, expansion and contraction, flexible orchestration, and easy expansion. However, the 5G user plane is not yet fully service-oriented. The control signaling interaction interface between the 5G core network and UPF (User Plane Function) has a preliminary definition of service-oriented, but lacks specific definitions of interface protocol stacks, message flows, etc. UPF and SMF (Session Management Function) still interact through the traditional interface. The control plane signaling uses the PFCPA (Packet Forwarding Control Protocol) protocol, and the user plane data uses the GTP-U (User plane of GPRS Tunneling Protocol) protocol. They interact by establishing and dismantling tunnels. The address of the other end of the tunnel requires multiple interactions to obtain. Once updated, it needs to be reconfigured, which makes the process complicated and inefficient. Summary of the invention

[0235] In order to more clearly describe the service-oriented interaction method provided by the embodiment of the present invention, several examples are provided below for illustration.

[0236] Example 1: UPF performs service registration process with NFR, such as Figure 4 As shown:

[0240] Example 2: UPF performs service update process to NFR, such as Figure 5 As shown:

[0241] Step 51, when the UPF update is triggered (such as UPF expansion), a service update request (Nfr_NFService_Update_Request) message is sent to the NFR, carrying the updated service information of the UPF service (such as traffic routing and forwarding; PDU session tunnel management; policy control; anchor point; customized service), UPF serving area; UPF network slice type indicator; UPF data network name (DNN); UPF interface information (interface); UPF ID; UPF address;

[0242] Step 52, NFR updates UPF service information and notifies UPF service users that the UPF service has been updated.

[0243] Step 53, NFR sends a service update response (Nfr_NFService_Update_Response) message to UPF to notify UPF that the service update is completed.

[0244] Example 3: UPF performs service deregistration process with NFR, such as Figure 6 As shown:

[0245] Step 61, UPF sends a service deregistration request (Nfr_NFService_Deregistration_Request) message to NFR, notifying NFR that the UPF service is no longer available, and carries a list of unavailable UPF services;

[0246] Step 62, NFR marks the UPF service in the unavailable UPF service list as unavailable, notifies the UPF service user, and deletes the UPF unavailable service information.

[0247] Step 63, NFR sends a service deregistration response (Nfr_NFService_Deregistration_Response) message to UPF, notifying UPF that the service deregistration is successful.
