Abstract
A method for selectively establishing a voice call continuity link between a mobile device and a voice call continuity application server includes the steps of receiving a request to establish a voice over IP call connection at the voice call continuity application server from the mobile device, the request including mobile device location information for the mobile device. The method determines at the voice call continuity application server whether the voice call continuity link is needed between the voice call continuity server and the mobile device responsive to the mobile device location information within the request and network location information stored within a database associated with the voice call continuity application server. The method establishes the voice call continuity link between the mobile device and the voice call continuity application responsive to a determination that the voice call continuity link is needed.
