METHOD AND APPARATUS FOR PERFORMING A HAND-OFF IN A WIRELESS COMMUNICATION SYSTEM

摘要

A method and apparatus for performing a hand-off in a wireless communication system (100) comprise a plurality of fixed communication units (102) and a controller (104) coupled to the plurality of fixed communication units (102), and further comprise a portable communication unit (120). The method comprises the steps of: receiving (504) from the controller a common master synchronization signal, and receiving (524) from the controller a request to monitor receivable transmissions from the portable communication unit (120) on the original channel. The method further comprises perfoming (526) synchronous monitoring of the receivable transmissions from the portable communication unit (120) on the original channel, the synchronous monitoring being synchronized by the common master synchronization signal.
