SYSTEM AND METHOD OF SUPPORTING PACKET-SWITCHED HANDOVER

摘要

A system and method of supporting packet-switched handover of a mobile st ation (MS) from a GERAN/UTRAN cell to a Generic Access Network (GAN) cell wi thin a GAN. If the MS is within coverage of the GAN cell, the MS registers w ithin the GAN, triggering initiation of the packet-switched handover from th e GERAN/UTRAN cell to the GAN cell. A preparation phase is then conducted fo r executing the packet-switched handover. The preparation phase includes ide ntifying the MS context as part of the preparation phase and activating the GA-PSR TC towards the MS. Next, the packet-switched handover is executed, re sulting in the MS switching to GAN mode . The MS then begins transferring pa ckets via the GAN cell. The system and method also supports a packet-switche d handover from the GAN cell to the GERAN/UTRAN cell.
