Method for controlling a Media Gateway

摘要

Access gateways in a packet-based network known in prior art have to log onto media gateway controllers that control said access gateways via standard protocols. The problem with said process is that switching to equivalent redundant devices takes too long. In order to minimize the time it takes to switch to equivalent devices, the access gateway simultaneously logs onto the at least two media gateway controllers such that at least two packet-based signaling connections are established while only one thereof is activated from the point of view of network services for the same plurality of users according to a specific selection criterion
