Method, apparatus, and media gateway for codec rate adjustment
First Claim
1. A method for codec rate adjustment, comprising:
- determining, by a media gateway (MGW), whether an initial codec rate of a first interface is consistent with an initial codec rate of a second interface when the MGW comprises the first interface and the second interface, wherein the first interface is an A interface between a base station subsystem (BSS) and the MGW, and wherein the second interface is a Nb interface between the MGW and a peer MGW;
determining, by the MGW, whether the initial codec rate of the first interface is consistent with an initial codec rate of a third interface when the MGW comprises the first interface and the second interface, wherein the third interface is an Iu interface between a radio network subsystem (RNS) and the MGW;
adjusting, by the MGW, the initial codec rate of the second interface to the initial codec rate of the first interface, without adjusting the initial codec rate of the first interface, when the MGW comprises the first interface and the second interface and the initial codec rate of the first interface is inconsistent with the initial codec rate of the second interface; and
adjusting by the MGW, the initial codec rate of the third interface to the initial codec rate of the first interface, without adjusting the initial codec rate of the first interface, when the MGW comprises the first interface and the third interface and the initial codec rate of the first interface is inconsistent with the initial code rate of the third interface.

Abstract
The present invention discloses a method for codec rate adjustment. A media gateway (MGW) determines whether an initial codec rate of a first interface is consistent with an initial codec rate of a second interface or an initial codec rate of a third interface, where the first interface is an A interface, the second interface is an Nb interface, and the third interface is an Iu interface; when determining that the initial codec rate of the first interface is inconsistent with the initial codec rate of the second interface or the initial codec rate of the third interface, the MGW adjusts the initial codec rate of the second interface or the initial codec rate of the third interface to the initial codec rate of the first interface. Therefore, quick and convenient codec rate adjustment can be implemented and voice service quality can be improved.
