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 after 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. The present invention using Generic Authentication Architecture can achieve management of the UE accessing the network and prevent unauthorized users from using the services in the network, especially the visited network.
