Method for controlling codec mode in all-IP network and terminal using the same

摘要

A method of controlling the codec mode of a convergence internet protocol (IP) network and a terminal using the method are provided. The terminal may include a variable bit-rate/mode codec controller including a channel status measurement and management (CSMM) unit which measures the status of a wireless channel and provides the results of the measuring of the wireless channel status as channel quality information, and which measures the transfer performance of a received packet and provides the results of the measuring of the packet transfer performance as packet measurement parameter information, and a service quality control (SQC) unit which measures the quality of a multimedia service based on the channel quality information and the packet measurement parameter information, provides the results of the measuring of the multimedia service quality as service quality information and determines a codec mode of the terminal or a counterpart terminal communicating with the all-IP terminal based on the service quality information. Therefore, it is possible to improve the quality of multimedia services.

1. A terminal, comprising:
a processor; and a codec controller, controlled by the processor, including a channel status measurement and management (CSMM) unit adapted to measure a status of a wireless channel as a first measurement and provide results of the first measurement as channel quality information, and measure a transfer performance of a received packet as a second measurement and provide results of the second measurement as packet measurement parameter information, and a service quality control (SQC) unit adapted to measure a quality of a service based on the channel quality information and the packet measurement parameter information, provide results of the measuring of the service quality as service quality information and determine a codec mode of the terminal in a convergence IP network communicating with the terminal based on the service quality information, wherein the status of the wireless channel and the transfer performance of a received packet are measured via a PHY/MAC(physical/media access control)-layer processor of a receiver.
