Abstract:
A wireless communication device (22) and method provides for the transmission of multiple data streams in a bandwidth-limited environment such that each of the data streams is afforded access to the transmission function in accordance with a priority. The priority may be determined on the basis of the application type, the TCP/IP four-tuple or other means. A data queue may be established during the active duration of each application and may be eliminated when the application has terminated or when the data queue is empty.
Abstract:
A method and apparatus for reducing access delay in push-to-talk (PTT) over Cellular (PoC) communication sessions is provided in a wireless communication device (120) including a quality level controller (230) which controls the quality level at which the transmit talkburst controller (226) provides talkbursts to transmitter circuitry (206). A processor (208) signals the quality level controller (230) and the transmit talkburst controller (226) to provide a first talkburst to the transmitter circuitry (206) for transmitting at a first quality level (310), and thereafter signals the quality level controller (230) to adjust the quality level from the first quality level to a second quality level (314) so that the transmit talkburst controller (226) will provide at least one subsequent talkburst to the transmitter circuitry (206) for transmitting at the second quality level (316).

Abstract:
A wireless communication terminal (300) including a radio transceiver (320), and a radio link control entity (310) that re-initiates a radio link control reset procedure when the transceiver receives a message containing an instruction to change an uplink or downlink protocol data unit size during an ongoing radio link control reset procedure. For example, the radio access network may initiate an uplink or downlink PDU size change before terminal receives acknowledgement that a previously initiated radio link control reset procedure is complete. The radio link control entity restarts a radio link control reset timer upon re-initiating the radio link control reset procedure after re-establishing radio link control.
