METHOD AND APPARATUS FOR FAST INTER-SYSTEM HANDOVER

摘要

Systems and methodologies are described that facilitate inter-system hand over in a wireless communication system. Various aspects described herein pr ovide for handover techniques that enable a target system to be prepared by a mobile device via a source system in order to minimize specific changes re quired to source system and/or target system. Techniques are described herei n in which the radio link of a source system can be utilized to tunnel signa ling messages which are in a format understood by a destination node in a ta rget system. Further, fast inter-access handover can be facilitated by estab lishing a simple generic transmission tunnel between respective network node s in source and target systems that handle intra-system mobility and providi ng a Layer 2 (L2) tunneling mechanism over the radio interface of each invol ved system technology.
