A system and method is provided for establishing a call to a wireless directory number ( 982 ) which is either a non-geographic directory number or a non-dialable directory number. A call is initiated from a wireline telephone ( 155 ) to a geographic-based local access directory number ( 994, 996 ). An originating switching node ( 810 ) recognizes the local access directory number ( 994, 996 ) as an AIN trigger, and thereafter identifies a signaling node ( 820 ) that is associated with the dialed local access DN ( 994, 996 ). The signaling node ( 820 ) sends a location request that includes the local access DN ( 994, 996 ) to an HLR ( 130 ). The HLR ( 130 ) obtains the wireless DN ( 982 ) from an internal database ( 990 ) in which the wireless DN ( 982 ) is associated with the local access DN ( 994, 996 ). The HLR ( 130 ) utilizes the wireless DN ( 982 ) to receive a temporary local directory number (TLDN) from visitor location register ( 140 ). The HLR ( 130 ) associates the TLDN with the local access DN ( 994, 996 ) and subsequently forwards the TLDN to the signaling node ( 820 ), which in turn relays the TLDN to the originating switching node ( 810 ). The call connection is thereafter established directly from the originating switching node in the end office to a visited cellular switch using the TLDN.
