ABSTRACT:
A method and system are provided which allow a wireline network to dynamically control call redirection at a wireline Service Control Point (SCP) for mobile subscribers. A wireless location register routinely updates the wireline SCP with information indicative of the operational status of a mobile termination unit. The SCP is arranged to maintain the mobile unit status in a resident database. When a call is placed to a subscriber's home telephone number, an SSP will query the SCP for routing instructions, and in response, the SCP will merely access its maintained database to determine the status of the mobile unit. The SCP either sends a mobile identification number or equivalent address to the SSP if the mobile is available, or the home telephone number if the mobile is unavailable.
