摘要：A communications network includes a data network that is coupled to a wirelessaccess network and other devices. The wireless access network enables access by mobile
stations of the data network. Each mobile station, and optionally, one or more of otherdevices coupled to the data network, contains an adaptive multi-rate codec
(coder/decoder) that can be set to operate at a plurality of rates. Based on the selectedone of the plurality of rates, the mobile station or other device sets a quality-of-service(QoS) indicator value in a packet carrying data, such as real-time data, over the wirelessaccess network and/or data network. By varying QoS requirements using the QoSindicator value for different codec rates, bandwidth requirements are varied so that moreefficient usage of the data network is provided.
