Abstract
The present invention provides an architecture for a media gateway to identify and register with multiple media gateway controllers for various types of voice and data services, along with having the media gateway appear to each of these media gateway controllers as a single, dedicated control entity. A logical layer, referred to as a virtualizer, is associated with each media gateway and appears to the media gateway as a single media gateway controller. To each media gateway controller the virtualizer supports, the virtualizer appears as a single media gateway. In essence, the virtualizer is a protocol manager and message router. The virtualizer supports the registration of multiple media gateways and then creates virtual gateways based on requirements of the media gateway controllers serving these virtual gateways. Preferably, subscribers associated with endpoints handled by the media gateway are grouped into a virtual gateway being served by a select media gateway controller or group thereof.
