Document Type and Number:
WIPO Patent Application WO/2022/174433
Kind Code:
A1
Abstract:
Disclosed in embodiments of the present application are a service authorization method, a system, and a communications device. The method comprises: a first network element obtains a first access token from a token generating network element, and sends to a second network element a first service request for a specified service, the first service request comprising the first access token. The first access token is used for indicating that an NF service consuming network element has the permission to access the specified service provided by an NF service providing network element and belonging to a specified service domain, and the first access token comprises an identifier of the NF service consuming network element, an identifier of the specified service, and first service domain information associated with the specified service domain. By carrying the first service domain information in the first access token, access control based on a service domain can be implemented, thereby facilitating improving the security of service authorization.
