Abstract: A dual mode device detects when its presence within a home wireless LAN. The dual mode device sends a message containing the BSSID of the HWLAN to an application on a WWC server, which associates the BSSID with the subscriber's identity in a dynamic database. When a call is dialed to the dual mode device, the WWC server application determines that the dual mode device is within the HWVLAN and causes the dual mode device and the HWLAN devices to ring. If a call is dialed to the HWLAN, the WWC server application looks up in a static database the user identity associated with the HWLAN and determines that the user subscribes to dynamic modification of the dial plan. The dynamic database, indexed on identity, is searched and determines that the user is within their HWLAN. Therefore, the dual mode device also rings when the HWLAN devices ring.
