Abstract
A method and apparatus for speeding up AAL connection setup during handover in advanced cellular networks. Connection parameters for the current AAL connection are bundled and transferred in a single message to be used setting up a new AAL connection in the coverage area. The method includes requesting a new AAL connection from a destination access network to a remote AAL peer by a serving access network, initiating an AAL connection setup by the destination access network upon receiving a handover request from a serving access network, bundling AAL connection parameters associated with an old AAL connection by the serving access network, transferring the bundled AAL connection parameters to the destination access network and establishing a new AAL connection to the remote AAL peer connection by the destination access network using the transferred AAL connection parameters. The transferring comprises encapsulating the AAL connection parameters within Radio Network System Application Part signaling. The serving access network may be a Base Station or a radio network controller. The destination access network may be a Base Station or a radio network controller.
