Towards Seamless Mobility Support with Cross-Layer Triggering

This paper presents mechanisms for collecting and processing cross-layer information from mobile devices and networks. That information is further used to feed the handover decisions as a part of the seamless mobility support. This paper presents a mechanism called Trigger Management, developed within the EU's Ambient Network project, for collecting and processing cross-layer trigger information. The trigger management system is bound to the VERHO vertical handover controller system, enabling the handover decisions based on several input parameters.
