A system and method of supporting packet-switched handover of a mobile station (MS) from a GERAN / UTRAN cell to a Generic Access Network (GAN) cell within a GAN. If the MS is within coverage of the GAN cell, the MS registers within the GAN triggering initiation of the packet-switched handover from the GERAN / UTRAN cell to the GAN cell. A preparation phase is then conducted for executing the packet-switched handover. The preparation phase includes identifying 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, resulting in the MS switching to GAN mode. The MS then begins transferring packets via the GAN cell. The system and method also supports a packet-switched handover from the GAN cell to the GERAN / UTRAN cell.

Disclosed is a method for determining Idle mode Signaling Reduction (ISR) activation in a mobile communications system.When a mobility management node decides to activate an ISR feature in an IMS network environment where hetero mobile communications networks (e.g., E-UTRAN and UTRAN / GERAN) interwork with each other, considered are not only whether an ISR feature can be supported, and whether a UE can use IMS voice, but also conditions (information) on whether IMS voice over PS domain can be supported. This may allow a voice call transferred to the UE from the network to be delivered to a domain (PS or CS domain) selected with consideration of an access network state without delay.
