System and method for a wireline-wireless network interface

Abstract

A single-number service for providing integrated wireless and wireline communication networks for forwarding a call incoming to a subscriber's designated single telephone number to a routing destination number based on the subscriber's current location is provided. The single-number service includes storing subscriber mobile registration status in a wireline location register (WLR) of the wireline communication network. The subscriber mobile registration status is retrieved upon receiving the call incoming to the subscriber's designated single telephone number. The call is routed to a wireline destination stored in the WLR in response to the subscriber mobile registration status indicating that the subscriber is wireline registered. A subscriber location request is sent from the WLR to the Home Location Register (HLR) of the wireless network in response to the subscriber mobile registration status indicating that the subscriber is wireless registered. A routing request is sent from the HLR to the MSC where the subscriber is registered in response to receiving the subscriber current location request. A wireless routing destination number (TLDN) is communicated from the MSC to the WLR. The call incoming to the subscriber's directory number is routed by the WLR to the wireless routing destination number (TLDN).
