Handoff method for a cellular system

摘要

A TDM cellular communication (100) system includes a plurality of repeaters (102) each providing communication coverage for a cell site. A plurality of communication units communicate with the repeaters. The communication units are handed off from one cell site to another by measuring the range of the communication units from the repeaters. If the range exceeds a predetermined range the received signal quality of the adjacent cell site repeaters are measured. An available cell site which provides the best received signal quality is selected by the communication unit for hand off.
