Abstract

A system and method is provided for establishing a call to a wireless directory number that comprises either a non-geographic directory number or a non-diable directory number. A call is placed from a wireline telephone to a preselected geographic-based access directory number (DN). The originating switching node, which may be an AIN-capable SSP, recognizes the access DN as an AIN trigger, and thereafter identifies a signaling node, which may be an AIN-capable SCP, that is associated with the dialed access DN. The originating switching node is then controlled to provide dialtone and collect digits from the caller, the collected digits corresponding to the non-geographic or non-dialable wireless directory number. Thereafter, the originating switching node transmits the collected digits to the signaling node. The signaling node sends a location request that includes the wireless DN to an HLR, which returns a temporary local directory number (TLDN) in accordance with ANSI-41 processing protocols. The call connection is thereafter performed directly from the originating switching node in the end office to a visited cellular switch using the TLDN. The method and system allows mobile location and call delivery using non-geographic directory numbers with a single call from any end-point.
