Abstract: A system and method for hand-off maintenance is disclosed. The present invention relates to communication networks and particularly, to network interfaces in communication networks. In existing hand-off mechanisms, when a restart occurs in a Media Gateway, the Media Gateway always tries to register back to the primary Media Gateway Controller, which is under maintenance. As the primary Media Gateway Controller cannot address the request, calls running on the Media Gateway will be affected leading to abrupt release of calls. The method provides a solution to the problem by rejecting service requests from the Media Gateway that are already handed off at the Media Gateway. Further, at Media Gateway level not to register requests to the primary Media Gateway Controller, when a primary Media Gateway Controller is under maintenance. When the primary Media Gateway Controller is under maintenance, requests are directed to the secondary Media Gateway Controller.

Abstract: Handoff of a media gateway (MG) from a primary media gateway controller (MGC) to a secondary MGC includes the primary MGC identifying a secondary MGC for performing MG handoff; and the primary MGC identifying a group of MGs, including at least one MG, to be handed off to the secondary MGC. If the group of MGs includes more than one MG, the following sequence is repeated—the primary MGC selecting a MG in the group; the primary MGC sending a handoff request to the MG, including identification of the secondary MGC; and the primary MGC standing by for a predetermined duration depending upon configuration of the MG.
