Abstract

A system for providing location data for determining which service provide is to receive a location based telephone call from a wireless telephone set. A list of call routing parameters for a wireless telephone is generated from the location of a wireless telephone. Each call routing parameter is a location descriptor which indicates location of a caller. A switching system then read each calling parameter from the list and attempts to find a service provider to receive the call. The switching system repeats the process until a service provider is determined. The call is then extended to the service provider.
