CONTEX TRANSFER IN A COMMUNICATION NETWORK COMPRISING PLURAL HETEROGENEOUS ACCESS NETWORKS

摘要

The present invention relates to a method for a context transfer in a communication network comprising a plurality of heterogeneous access networks, (220, 221, 222) wherein a mobile terminal is attached to one of the access networks. Further, the present invention relates to a context transfer manager performing the method (220, 600). Moreover, the present invention relates to a mobile terminal specially adapted to perform the provided method for a context transfer. To facilitate a context transfer between heterogeneous access networks, the present invention introduces a context transfer manager generating at least one context based on capabilities and parameters associated to the mobile terminal and capabilities and parameters of the neighboring access networks taking into account the respective access technology (Fig.5). Further the context transfer manager is common to the heterogeneous access networks in the communication network and performs the context transfers related to a particular mobile terminal.
