Streamlined initiation of a call transfer within a cellular telephone network is effectuated by having the transfer-to C-number request include not only an identification of the B-number for the called mobile station, but also an identification number of a switching node presently handling the call. Responsive to receipt of this request, the home location register processes the B-number to identify one or more C-numbers for forwarding of the call. The home location register then determines which switching nodes currently serve the identified C-numbers and directly generates a routing request message, including the received present switching node identification number, to each of those switching nodes. This action bypasses the conventional TIA IS-41 signaling actions of returning the identified C-numbers to the present switching node and generating a location request message for delivery back to the home location register. |
