method and device for accelerated connection during the weiterreichens in advanced cellular networks

摘要

A method and apparatus for speeding up AAL2 connection setup during handover in advanced cellular networks. Connection parameters for the current AAL2 connection are bundled and transferred in a single message to be used setting up a new AAL2 connection in the coverage area. The method includes requesting a new AAL2 connection from a destination access network to a remote AAL2 peer by a serving access network, initiating an AAL2 connection setup by the destination access network upon receiving a handover request from a serving access network, bundling AAL2 connection parameters associated with an old AAL2 connection by the serving access network, transferring the bundled AAL2 connection parameters to the destination access network and establishing a new AAL2 connection to the remote AAL2 peer connection by the destination access network using the transferred AAL2 connection parameters. The transferring comprises encapsulating the AAL2 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.
