Abstract
A telecommunication system and method for controlling the establishment of payload connections through media gateways. The system receives and aggregates control orders from a plurality of telecommunication nodes such as media gateway controllers. The system uses knowledge of resources in the network to optimize the path of the payload connection. The system also sends control orders to a given media gateway in order to establish the payload connection. The system may be connected to a plurality of other instances of the same type of system in a hierarchical manner.
Claims14
A telecommunication system for controlling media gateways in a telecommunication network, said system comprising:
- a plurality of media gateway proxies connectible to a plurality of media gateway controllers, so as to create pairs, where each of the pairs comprises a media gateway proxy and an associated media gateway controller connectible together by a media gateway controller interface, each media gateway proxy in the telecommunication network receiving signaling messages from the media gateway proxy's associated media gateway controller;
- a media gateway control module having a separate internal interface for each of the plurality of media gateway proxies and a media gateway control layer interface for a telecommunications node which is coupled with the media gateway control module through at least one media gateway;
- wherein the media gateway proxies are configured to extract media gateway control orders in the signaling messages received from the media gateway controller and to send the control orders to the media gateway control module;
- wherein the media gateway control module is configured to:
- aggregate the media gateway control orders received from at least two of the media gateway proxies;
- calculate an optimal path for a payload connection based on the aggregated media gateway control orders and network resources known to the media gateway control module;
- and
- order establishment of the payload connection in the media gateway by sending media gateway control signaling messages to the media gateway on the media gateway control layer interface.
A method of ordering the establishment of a connection in a media gateway in a telecommunication network, said method being executed in a media gateway control module, the method comprising the steps of:
- receiving from a first media gateway proxy on a first internal interface of the media gateway control module, control orders from extracted signaling messages from a first media gateway controller;
- receiving from a second media gateway proxy on a second internal interface of the media gateway control module, control orders extracted signaling messages from a second media gateway controller;
- aggregating the extracted control orders in a connection services portion of the media gateway control module;
- calculating in a connection coordination portion of the media gateway control module, a physical path through the telecommunication network;
- and
- ordering by the connection coordination portion the establishment of the connection in the media gateway by sending media gateway control signaling messages to the media gateway, wherein the connection belongs to the physical path.
