Context transfer in a communication network comprising plural heterogeneous access networks
First Claim
1. A method for a context transfer in a communication network comprising a plurality of heterogeneous access networks wherein a mobile terminal is attached to one of the access networks, the method comprising:
- receiving location information at a context transfer manager, wherein the context transfer manager is common to the plurality of heterogeneous access networks in the communication network,determining by the context transfer manager neighboring access networks for the mobile terminal based on the location information,generating by the context transfer manager at least one context for the neighboring access networks and the mobile terminal,transmitting by the context transfer manager a context to each of the neighboring access networks and the mobile terminal,wherein the generation of the at least one context is 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, andwherein the context transfer manager common to the plurality of heterogeneous access networks performs the context transfers related to said mobile terminal.

Abstract
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.
