Abstract
A location method and system for a mobile communication system having a plurality of zones and a plurality of sectors in each zone. The location method and system locate a zone and sector in a zone where a mobile station is located. In the location system a base station associated with each zone transmits a control channel signal and transmits a sector signal for each sector in the zone. Each control signal of a zone differs from control channel signals of other zones. Each sector signal differs from other sector signal and control channel signals. A mobile station controller associated with each mobile station receives the control channel signals, determines which zone the mobile station is in as a location zone based on the received control channel signals, receives sector signals for sectors within the location zone, and determines which sector of the location zone the mobile station is in as a location sector based on the received sector signals.
