METHOD FOR DETERMINING WHEN A COMMUNICATION UNIT IS LOCATED WITHIN A PREFERRED ZONE

摘要

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.
