System and method for providing codec information in a mobile communication network

摘要

A method and system for improving a codec negotiation procedure so that a call setup time can be reduced in an International Mobile Telecommunications (IMT)-2000 network. A media gateway (MGW) connects a radio network controller (RNC) of a radio access network accessed by at least one user equipment (UE) to another network. A mobile switching center (MSC) server controls connections of the RNC and the MGW, determines the codec information for the UE through codec negotiation when the UE makes a call setup request, and directly provides the determined codec information to the MGW through an additional request message based on a MEGACO interface so that the codec information can be used when the MGW sets up a path associated with a requested call.
