Abstract
The present invention provides a method for improving the communication coverage in a multi-cell communication system (,) which employs neighbor cell lists. A cell site (,) provides a communication unit (,) within its cell (,) with communication and a neighbor cell list. The neighbor cell list (,) 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 (,) has entered another cell and/or needs to hand-off its communication to another cell site but has been denied, the cell site (,) sends the communication unit the neighbor cell list related to the new cell. With a new neighbor cell list (,), the communication unit (,) 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.
