  • Inter-network handoff method
    Patent number: 7477625
    Abstract: An inter-network handoff system and method are disclosed, and include determining, by a setting BS, whether or not there exists a pilot stronger than a threshold value according to a PSMM received from a mobile station (MS), selecting a BS of which pilot is stronger than the threshold value as a target BS, determining whether or not the MS can accommodate a packet data service provided by the target BS, configuring the MS so as to accommodate the packet data service of the target BS, starting communication between the MS and the target BS, and terminating communication between the MS and the serving BS. Accordingly, a soft handoff can be performed between two systems having different data rates.
