Abstract:
A method and apparatus for improved context transfer in heterogeneous networks is presented. Context information is collected from source entities in a first access network by a context transfer manager and transmitted to a context transfer manager of a second access network which forwards the context information to target entities therein. In one of the context transfer managers at least a part of the context information is translated from a format supported in the first access network to another format supported in the second access network. The method may be carried out proactively preceding a handover or reactively following a handover. In one embodiment, context transfer within one access domain is performed directly between access routers, whereas context transfer between different access domains is performed via the context managers. In another embodiment, beacons from access points are counted in order to determine candidates for a pending handover.
