Method and system for using low data rate vocorder packets to multiplex signaling packets into a CDMA traffic channel for high quality CDMA voice transmission

摘要

In a CDMA based wireless digital communications system, a CDMA communications station. The CDMA communications station includes a signal encoder adapted to encode signaling information into a series of signaling packets, wherein the signal encoder process the signal information into variable size signaling packets in accordance with an amount of the signaling information. A voice encoder is included in the station and is adapted to encode voice information and process the voice information into a series of voice packets, wherein the voice encoder processes the voice information into variable size voice packets in accordance with an amount of the voice information. A multiplexer is included in the station wherein the multiplexer is coupled to receive the voice packets and coupled to receive the signaling packets and for combining the voice packets and the signaling packets into a traffic frame. A transmitter is coupled to the multiplexer for transmitting the traffic frame as received from the multiplexer. The multiplexer is further adapted to include the signaling packets into the traffic frame with the voice packets such that more signaling information is included in traffic frames having smaller voice packets with respect to signaling information included in traffic frames having larger voice packets such that the size of the voice packets are not constrained by the transmission of signaling packets.
