Abstract:
In a CDMA based wireless digital communications system, a CDMA communications station comprising:a signal encoder adapted to encode signaling information into a series of signaling packets, wherein the signal encoder processes the signal information into variable size signaling packets in accordance with an amount of the signaling information; a voice encoder 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 coupled to receive the voice packets and coupled to receive and buffer the signaling packets and for combining the voice packets and the signaling packets into a traffic frame; and a transmitter coupled to the multiplexer for transmitting the traffic frame as received from the multiplexer; wherein the multiplexer is adapted to determine, based at least in part on an early indication signal, that a less than full rate voice data packet is to be included in an outgoing traffic frame, and is further adapted to include an amount of buffered signal packet in the outgoing traffic frame so as to fill at least a portion of the traffic frame that is unused by the voice data packet; and wherein the early indication signal is provided to the multiplexer by the voice encoder.
