System and method for a wireline-wireless network interface

A method for providing an interface between wireless and wireline communication networks for exchanging subscriber status information in order to map a call incoming to a subscriber's wireline Directory Number (DN) to a subscriber's wireless mobile location through a Service Switching Point (SSP), the method comprising:

• communicating wireless registration status data from a mobile service controller (MSC) of the wireless communication network to a wireline location register (WRL) located in a Service Control Point (SCP) of the wireline communication network;
• storing the wireline registration status data in the WLR;
• sending a subscriber current location request from the WLR to a Home Location Register (HLR) of the wireless network in response to the wireline registration data indicating that the subscriber is wireless registered;
• sending a query at the HLR to the MSC where the subscriber is located in response to receiving the subscriber current location request, the query requesting a wireless routing destination number;
• communicating a Temporary Location Destination Number (TLDN) from the MSC to the WLR;
• and
• routing the call from the SSP to the MSC for delivery to the TLDN.

A method for providing a single-number service adapted for use in wireless and wireline communication networks for exchanging network status information in order to selectively route a call incoming to a subscriber's single telephone number to either a subscriber's wireless or wireline location depending on the wireless registration status of the subscriber, the method comprising:

• communicating wireless registration data from a mobile switching center (MSC) to a Home Location Register (HLR) in the wireless network;
• communicating the wireless registration data from the HLR to a wireline location register (WLR) when the subscriber becomes registered in the wireless network;
• storing the wireless registration data in the WLR;
• communicating a location request query from the WLR to the HLR to determine a location of the subscriber, in response to receiving notification of an incoming call;
• generating a routing request query from the HLR to the MSC to determine a routing destination for the subscriber;
• responding to the WLR by the MSC the location and the routing destination of the subscriber;
• and
• routing the call to a wireless routing destination number (TLDN) in the wireless network corresponding to the location of the subscriber in response to the subscriber being registered in the wireless network.

For use in an integrated wireless/wireline communication network, a system for providing an exchange of network status information in order to route a call incoming to a subscriber's single telephone number to either a subscriber's mobile unit through a Mobile Services Controller (MSC) or to a subscriber's customer premises equipment (CPE) through a Service Switching Point (SSP) depending on the location of the subscriber, the system comprising:

• a Wireline Location Register (WLR) located in the wireline communication network and in electrical communication with the SSP for storing subscriber routing information and subscriber registration status data;
• a Home Location Register (HLR) located in the wireless communication network and in electrical communication with the WLR and the MSC for storing and communicating to the WLR subscriber routing information and subscriber registration status data;
• and
• a service control point (SCP) located in the wireline communication network and provided in electrical communication with the WLR and the SSP, the SCP operable to retrieve the subscriber routing information and provide the subscriber routing information to the SSP.
