Methods, systems, and computer program products for providing transcoder free operation (TrFO) and interworking between unlicensed mobile access (UMA) and universal mobile telecommunications system (UMTS) call legs using a media gateway
First Claim
1. A media gateway for establishing a transcoding free connection between unlicensed mobile access (UMA) and universal mobile telecommunications service (UMTS) legs of a connection, the media gateway comprising:
- (a) at least one broadband interface for sending media packets to and from a UMA leg and a UMTS leg of a connection;
(b) a packet switching fabric for forwarding media packets between the at least one broadband interface and at least one internal processing resource of the media gateway;
(c) at least one voice server for performing voice processing functions for media packets received from the UMA leg and the UMTS leg; and
(d) a UMA-UMTS transcoder free operation controller for establishing a transcoding free connection within the media gateway between the UMA and the UMTS legs via the at least one broadband interface, the packet switching fabric, and the at least one voice server.

Abstract
Methods, systems, and computer program products for establishing transcoding free connections between UMA and UMTS call legs are disclosed. According to one method, a media gateway determines whether codec configurations used by UMA and UMTS legs of a call are compatible. In response to determining that the configurations are compatible, media gateway determines whether rate control is necessary to establish a transcoding free connection. In response to determining that rate control is necessary, the media gateway issues rate control requests on the UMA and UMTS legs as appropriate. The media gateway determines whether the rate control requests are successful. In response to determining that the requests are successful, the media gateway establishes a transcoding free connection between the UMA and the UMTS legs of the call.
