System and method for controlling media gateways that interconnect disparate networks

A method for selecting a circuit service call channel, comprising:

• receiving a request for a circuit service call channel, said request comprising information identifying a media gateway selected out of a plurality of media gateways, said selected media gateway having a Time Division Multiplexed (TDM) circuit selected out of a plurality of TDM circuits associated with it;
• and
• selecting an Asynchronous Transfer Mode (ATM) Virtual Circuit Channel Connection (VCC) from a plurality of ATM VCCs associated only with said selected media gateway;
• and
• transmitting an Establish Request (ERQ) to a Q.2630 module of a signaling gateway.

A method for controlling media gateways, comprising:

• receiving a circuit service call setup request from a mobile system;
• selecting, by a Mobile Switching Center (MSC), a Time Division Multiplexed (TDM) circuit of a plurality of TDM circuits associated with a media gateway of a plurality of media gateways in response to receiving said circuit service call setup request;
• transmitting a request for a circuit switched channel to a Radio Network Controller (RNC) via a signaling gateway, said request including an address of said selected TDM circuit;
• selecting an ATM Virtual Channel Connection (VCC) of a plurality of ATM VCCs associated only with said media gateway;
• and
• transmitting information regarding an ATM channel of said selected ATM VCC to said MSC for establishment of said circuit service call.

A system for controlling media gateways, comprising:

• a plurality of media gateways, each of said plurality of media gateways having a plurality of TDM circuits associated with it;
• a call originating node operable to select a Time Division Multiplexed (TDM) circuit associated with a media gateway of said plurality of media gateways in response to receiving a circuit service call setup request from a mobile system;
• a signaling gateway comprising a Q.2630 module operable to control said plurality of media gateways;
• and
• a call terminating node operable to select an ATM Virtual Channel Connection (VCC) of a plurality of ATM VCCs associated only with said media gateway, in response to receiving a request for a channel, said call terminating node further operable to transmit information regarding a selected channel of said selected ATM VCC to said call originating node for establishment of said circuit service call.

A system for controlling media gateways, comprising:

• a Mobile Switching Center (MSC) operable to select an Application Adaptation Layer type 2 (AAL-2) path associated with a media gateway of a plurality of media gateways in response to receiving a circuit service call setup request from a mobile system;
• a signaling gateway operable to translate an address of said selected AAL-2 path into an address of said media gateway with which said selected AAL-2 path is associated;
• and
• a Radio Network Controller (RNC) operable to select an ATM Virtual Channel Connection (VCC) of a plurality of ATM VCCs associated only with said media gateway based at least in part on said address of said selected media gateway, in response to receiving a request for a channel, said RNC further operable to transmit information regarding a selected channel of said selected ATM VCC to said MSC for establishment of said circuit service call.
