Embodiment approach 1

[0146] Embodiment 1, the above access token request message may also carry the network function type of the client and / or the network function type of the first server, the network function type of the second server and a list of expected service names, so that the authorization server can The function type and / or the network function type of the first server, the network function type of the second server and the expected service name list, determine the second server that authorizes the client and / or the first server to access the network function type, and generate access token. The access token also includes a list of network function types and desired service names of the second server.

Embodiment approach 2

[0147] Embodiment 2, the above access token request message may also carry the instance identifier of the second server and a list of expected service names. For example, the desired server's service name list may include one or more second server's service names. So that the authorization server determines, according to the instance identifier of the second server and the expected service name list, that the client and / or the first server are authorized to access the second server corresponding to the instance identifier of the second server. Therefore, optionally, the above-mentioned access token may also include an instance identifier and a list of service names of the second server.

[0148]Optionally, in the above two implementation manners, the access token may further include an instance identifier of the authorization server, which is used to indicate the identity information of the authorizer of the access token.

[0149] Optionally, in the above two implementation m...

Abstract

The embodiment of the invention discloses a service authorization method and a communication device, and can solve the problem that a first server accesses a second server and does not obtain serviceauthorization in a scene that the second server is discovered by a client, so as to reduce the security risk of a servitization network. The method comprises the following steps that: a client replaces an access token for applying for a first server to access a second server and informs the first server; or, the first server applies for the access token by itself according to an instance identifier or resource identifier of the second server provided by the client.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a service authorization method and a communication device. Background technique [0002] In a network deployed with a service-based architecture (SBA), such as the core network (CN) of the fifth generation (5G) mobile communication system, different network functions are usually based on the client ( client) / server (server) communication mode for communication. The requester is the client and the responder is the server. In order to prevent any client from accessing the server and bring security risks to the mobile communication system, and to support limited access to resources by third-party clients, the service architecture also supports service authorization functions. Specifically, the server may include an authorization server (authority server) and a function server (function server). The client applies to the authorization server for the authoriz...
