Abstract
The present invention provides a communication system (100) and a method for determining when a communication unit (105) is located within a preferred zone in the cellular communication system (100). The cellular communication system (100) includes a plurality of cells. A preferred zone for a communication unit (100) is created. Radio characteristics associated with the preferred zone, such as pilot signal, cell ID, and distance, are obtained. It is then determined, based at least in part upon the radio characteristics, when the communication unit (100) is located within the preferred zone.

A method for determining when a communication unit is located within a preferred zone in a cellular communication system, the cellular communication system including a plurality of cells, the method comprising the steps of:
- creating a preferred zone for a communication unit, wherein the preferred zone is defined by a specific cell, a pilot channel information, a pseudo-random (PN) offset code, and a range offset value corresponding to a distance of the preferred zone from a center of a cell;
- obtaining radio characteristics associated with the preferred zone;
- and
- determining, based at least in part upon the radio characteristics, when the communication unit is located within the preferred zone.
