ABSTRACT:
The present invention provides a method for improving the communication coverage in a multi-cell communication system (100) which employs neighbor cell lists. A cell site (114) provides a communication unit (128) within its cell (112) with communication and a neighbor cell list. The neighbor cell list (200) informs the communication unit of other cells which are possible hand-off targets. When the fixed network equipment (FNE) detects that a particular communication unit (128) has entered another cell and/or needs to hand-off its communication to another cell site but has been denied, the cell site (114) sends the communication unit the neighbor cell list related to the new cell. With a new neighbor cell list (300), the communication unit (128) can now attempt to maintain its communication by handing-off to cells unknown before. In this manner the effective communication coverage of the system is improved.
