ABSTRACT:
The present invention discloses a method for releasing a service tunnel in WLAN. This method comprises: an originating end point that desires to release a service tunnel in a WLAN sending a release tunnel request to a corresponding end point of the service tunnel; the corresponding end point returning a release acknowledgement to the originating end point, and releasing resources of the service tunnel, a Packet Data Gateway (PDG) sends a tunnel disconnection report to a service authentication and authorization unit, and upon receiving the tunnel disconnection report, the service authentication and authorization unit updates self-stored information related to the released service tunnel. The method in accordance with the present invention makes it possible to implement the release of a designated service tunnel and release or update the related resources and information in time.
