Abstract
A paging system (10) includes any number of spaced apart transmitters (12), each of which has its own area (15) of coverage. A population of subscriber units (24) freely roams between the areas (15). When a subscriber unit (24) roams to a new area (15), a call is placed from a telephone instrument (22) to a destination controller (28) through the public switched telecommunication network (21). A subscriber ID and location data are transferred to the system (10) during this call. The location data are used internally by the system (10) to route pages to only the transmitters (12) whose areas (15) correspond to the location data, and only these transmitters (12) broadcast the pages. Subscriber units (24) may generate the location data which the system (10) uses in routing pages to transmitters (12). A position-determining receiver (42) may directly obtain location data from a positioning system (34). Alternatively, location data may be obtained from transmissions broadcast by the transmitters (12).
