Abstract

A method for managing codec information of Media Gateways (MGWS) in a Mobile Switching Center (MSC) server, comprising receiving a registration request from at least one or more MGWs, registering the request MGW, and transmitting a codec information request message to the registered MGW to thus update MGW codec information that the MSC server itself manages using the codec information received from the MGW.

Claims

1. A Media Gateway (MGW) codec information managing method in a Mobile Switching Center (MSC) server which interworks with at least one or more MGWs, comprising:

receiving a registration request from the MGW;

registering the requested MGW; and

transmitting a codec information request message to the registered MGW, and thus updating MGW codec information using the codec information received from the corresponding MGW.

2. The method of claim 1, wherein the MGW codec information is codec information used in each MGW.

3. The method of claim 1, wherein the codec information request message is a message used when desiring to know information with respect to a termination of the MGW.

4. The method of claim 3, wherein the codec information request message is an AuditValue.

5. The method of claim 1, wherein the codec information request message is created when the MGW is registered, the MSC server generates a new codec type using a Man Machine Command (MMC) command, or an operator manually requests an updating of the MGW codec information.

6. The method of claim 1, wherein the updating includes:

requesting the updating of the codec information from a Media Gateway Control (MEGACO) processing unit by a Man Machine Command (MMC) command processing unit;

transmitting a codec information request message to the MGW by the MEGACO processing unit;

transmitting a codec information reply message to the MEGACO processing unit by the MGW;

using codec information contained in the codec information reply message, by the MEGACO processing unit, to update the codec information used in each MGW; and

notifying the MMC command processing unit of a completion of the updating of the codes information when the codec information is completely updated.

7. The method of claim 6, wherein the codec information updating request is transmitted when the MGW is registered, the MMC command processing unit generates a new codec type, or an operator requests the updating of the codec information.
