Method and system for providing mobile handover across multiple media gateways controlled by the same call server

摘要

The present disclosure describes a system and method for handing off a mobile device from ananchor wireless media gateway (WMG) to a target WMG, where both WMGs are controlled by a single call server. In one example, the anchor WMG includes first and second termination points connecting the first WMG to the mobile device and another party, respectively. The method includes creating fourth and fifth termination points in the target WMG to provide an interface for the target WMG to communicate with the mobile device and the anchor WMG, respectively. A third termination point may be established in the anchor WMG, and the third and fifth termination points may link the first and second WMGs. A context may be created using the second and third termination points, and the third termination point may be made bi-directional.
