    Abstract: A method and apparatus for allowing a transparent service option transition between at least two wireless communication devices (WCDs). A first communication between a first WCD and a second WCD is established using a first service option. At some point during the first communication, a transition to a second service option, such as an asynchronous data service option, is initiated. At least one of the WCDs provides an identification code to the other WCD using a signaling protocol over the first service option. The first communication is then terminated. A second communication using the second service option is then initiated by one of the WCDs, resulting in a seamless transition to the second service option.

    Abstract: A method and apparatus for efficient data retransmission in a voice-over-data communication system between a first wireless communication device and a second wireless communication device, without affecting existing infrastructure. When a data frame containing audio information is received in error by the first wireless communication device, n negative-acknowledgement messages are sent from the first wireless communication device to the second wireless communication device which sent the frame, the n negative acknowledgement messages transmitted interleaved with normal data frames. When a negative-acknowledgement message is received by the first wireless communication device from the second wireless communication device, n copies of the frame identified by the negative-acknowledgement message is transmitted by the first wireless communication device, the copies transmitted interleaved with normal data frames.

    Abstract: A method and apparatus for reducing transmission overhead in a wireless communication system. In one embodiment, the apparatus is directed to a communication device comprising a processor for transmitting a data origination message, the data origination message initiating a data communication with a receiving station. Information needed to construct datagrams are also transmitted by the apparatus to the receiving station. The receiving station receives the data origination message and the information needed to construct datagrams and configures a packet data generator for sending datagrams to a destination device. Data network header information is constructed from information provided by the information needed to construct datagrams.

    Abstract: A method and apparatus for reducing voice latency in a voice-over-data wireless communication system. In a transmitter, audio information to be transmitted is first encoded using a voice encoder operating in a first mode of operation. At least one operating parameter in the transmitter is measured by a processor, the least one operating parameter proportional to a latency between the transmitter and receiver. If the at least one operational parameter exceeds a predetermined threshold, the voice encoder is instructed to operate in a second mode of operation. When the at least one operational parameter falls below a second predetermined threshold, the voice encoder is instructed to operate in the first mode of operation.
