Embodiment Construction

[0103] The embodiments of the present application provide an authorization method and device of a service-based architecture, which are used to implement the service provider network function to verify the validity of the service request after introducing the SCP in the authorization process. Wherein, the method and the device are based on the same inventive concept, and since the principles of the method and the device to solve problems are similar, the implementation of the device and the method can be referred to each other, and the repetition will not be repeated.

[0104] Some of the terms involved in the embodiments of the present application are explained below for easy understanding.

[0105] 1) Certificate (certificate): Refers to a digital certificate, a document digitally signed by a Certificate Authority (CA) that contains public key owner information and a public key, and is used for identity authentication of both communication parties. The certificate contains c...

Abstract

The embodiment of the invention discloses a service architecture authorization method and device. The method comprises the steps: generating a token by a first network storage function network element after receiving a token request, and writing the service communication proxy (SCP) certificate information in the token by the first network storage function; returning the token carrying the certificate information to a sender of the token request; receiving a service request by the service provider network function, wherein the service request carries a token containing the SCP certificate information or carries the token and a certificate information verification result; if the service request does not contain a certificate information verification result, verifying the certificate information of the SCP by the service provider network function; and if the verification result is successful, continuing the authorization process. According to the technical scheme, the problem that after a service communication agent is introduced, the network function of a service provider cannot verify the certificate information in the token can be solved.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular to a method for service-based architecture authorization. Background technique [0002] The fifth generation mobile communication system (the Fifth Generation, 5G) adopts a service-based architecture (Service Based Architecture, SBA). The 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) also proposes an enhancement of Service Based Architecture (eSBA). In the SBA or eSBA, all network functions (Network Function, NF) support transport layer security (Transport Layer Security, TLS). NFs allow other authorized NFs to access their services. The network storage function (NF Repository Function, NRF) provides services such as management, discovery and authorization for NF. The service requester NF obtains the token corresponding to the service by requesting authorization from the NRF, and the NRF also writes the certificate information ...
