ABSTRACT:
In a method of routing a call to a wireless telephone service subscriber entitled to the call routing service, the subscriber is assigned a numbering plan number. The number of the nearest fixed station is determined. The number of the nearest fixed station is written into the database of a service control point serving the subscriber. For each call to be routed, the nearest fixed station number is read from the database of the service control point. A word identifying the telephone is then sent to the fixed station designated by the nearest fixed station number. This fixed station then sends at least one call message containing the word identifying the telephone of the subscriber and the number of the fixed station. The call message is received by the telephone of the subscriber, the word identifying that telephone is recognized and the subscriber is alerted. A call is set up between the subscriber and the fixed station by sending from the subscriber's telephone to the fixed station a response message containing the word identifying the telephone and the number of that fixed station.
