ABSTRACT:
A hand-off method for reducing probability of call disconnection during hand-off in a digital personal communication service (PCS) system, comprising the steps of: forming a link path between a plurality of gateway communication interconnection networks (GCINs) by using interprocess communication (IPC) to connect base station controllers (BSCs) to each other; allocating a high capacity IPC node board assembly (HINA) address for distinguishing between the GCINs in order to perform the hand-off by means of the interprocess communication between the various GCINs; and handing-off a call by using the HINA address and a link path between the GCINs, in response to a hand-off request.
