Summary:This invention relates to a wireless communications system providing call transfer for an incoming call to a mobile subscriber unit. A wireless communications system provides call transfer capability for an incoming call to a mobile subscriber unit. The mobile subscriber unit requests the call transfer to a serving MSC. The serving MSC relays the request to a home location register, and the home location register executes the request by initiating the call transfer in conjunction with an originating MSC. This arrangement obviates the need for supporting call transfer on the serving MSC and the need for inter-MSC facilities once the call transfer is completed. Moreover, the approach of the present invention enables call transfer to be ubiquitously supported within a wireless communications system.
