System and method for managing user equipment to access networks by using generic authentication architecture

摘要

The present invention discloses a method for managing user equipment (UE) to access the network by using Generic Authentication Architecture. The basic technical solution of the present invention is that upon receiving a B-TID query request from a NAF, a network function which provides query information determines whether the UE is authorized to use the service in the network. If yes, the network function returns a successful query response carrying the information queried by the NAF to the NAF, and then, the NAF communicates with the UE according to the successful query response; otherwise, the network function returns a failed query response to the NAF and the NAF rejects the access from the UE. A system for managing user equipment to access networks by using Generic Authentication Architecture is also disclosed, which includes a Network Application Function (NAF) and a network function to control the UE network service utilizing conditions.
