Problems solved by technology

[0005] In the prior art, after establishing a binding relationship between the service instance 1 of the NF service producer and the service instance 1 of the NF service consumer in the indirect communication mode, the SCP still needs to perform rules based on the address of the service instance 1 of the NF service producer Matching and routing, and ensuring that service requests of service instance 1 are routed to service instance 1, the process is more complicated

Abstract

The embodiment of the invention provides a service binding method and device, relates to the technical field of communication, and aims to simplify the communication process between two network functions for establishing a binding relationship in an indirect communication mode and improve the information forwarding performance. The method comprises the steps that a first network function sends a request of a first service to a first service communication agent SCP, wherein the request of the first service is used for requesting the first service; the first network function receives a response of the first service from the first SCP, wherein the response of the first service comprises first routing information, the first routing information comprises an address of an SCP passed from the first network function to a second network function and an address of a first service instance of the second network function, and the first service instance of the second network function is used for providing service for the first network function.

Description

Technical field[0001]The present application relates to the field of communication technologies, in particular, to a method and apparatus for service binding.Background technique[0002]Third Generation Partner Program (3rd Generation Partnership Project, 3GPP) RELESE 15, fifth generation mobile communication technology (5TH Generation, 5G) The core network system architecture is based on service based architecture (SBA). The main purpose of SBA is to split each network function (NF Service) (NF Service) Each network function service can be interoperable by standard interfaces and other network function services, where NF with service consumer function is called NF service consumers, and has NF with service producers. For NF service producers, NF service producers and NF service consumers can include one or more service instances.[0003]The 3GPP Release 16 further improves and optimizes the service-based architecture of Release 15, and the indirect communication mode is proposed, and ...
