摘要:
A system and method for improved mobile assisted handoff in a digital cellular communication system that gives the mobile station the ability to synchronize to candidate base station transmissions in order to read the transmitted digital voice color code (DVCC) of the candidate station. This process is performed during the idle period between two designated time slots in a TDMA frame. The invention is an enhancement to the existing mobile assisted handoff procedures described in the existing IS-136 standard. The present invention improves on the IS-136 standard's use of received signal strength measurements in that it allows the mobile station to acquire and report information regarding the digital verification color code (DVCC) of the candidate base station channels. Since the DVCC uniquely identifies the cell site to which a channel belongs, it is used to distinguish the candidate base station channel from its co-channel interferers, allowing the network to make a more informed handoff decision.
