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 either an initial codec rate of a second interface or an initial codec rate of a third interface, wherein the first interface is an A interface between a base station subsystem (BSS) and the MGW, the second interface is an Nb interface between the MGW and a peer MGW, and the third interface is an Iu interface between a radio network subsystem (RNS) and the MGW;
adjusting, by the MGW, either 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 when the initial codec rate of the first interface is inconsistent with either the initial codec rate of the second interface or the initial codec 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 lu 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.

8. An apparatus for codec rate adjustment, comprising:
-
a determining unit configured to determine whether an initial codec rate of a first interface is consistent with either an initial codec rate of a second interface or an initial codec rate of a third interface, wherein the first interface is an A interface between a base station subsystem (BSS) and a media gateway (MGW), the second interface is an Nb interface between the MGW and a peer MGW, and the third interface is an Iu interface between a radio network subsystem (RNS) and the MGW; an adjusting unit configured to adjust either 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 when the determining unit determines that the initial codec rate of the first interface is inconsistent with either the initial codec rate of the second interface or the initial codec rate of the third interface. - View Dependent Claims (9, 10)
