Abstract
A method of establishing call termination to a mobile station of a called subscriber in a fixed wireless communication network which can be only allowed to receive call terminations in one of its HomeZones. The identification and location of the MS is ascertained prior to routing a call to the switching center serving the MS. The radio link between the serving switching center and the MS is maintained and used to terminate a call if the MS is determined to be within a HomeZone. The present invention eliminates the need to page a MS twice thereby speeding up the call termination. The MS provides its location area code and Cell ID to the serving/visited mobile switching center to facilitate the SCP identifying the MS's location prior to routing the call termination to the MS. The HomeZone call may be routed to a mobile station voicemail if it is determined to be outside its HomeZones, or, terminated to the mobile station but at a higher wireless billing rate.
