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.

Abstract: A method and apparatus for reducing voice latency in a voice-over-data wireless communication system. In a transmitter, data frames are created from audio information by a vocoder and stored in a queue. Prior to storage, some of the data frames are eliminated, or dropped, and are not stored in the queue. In a receiver, data frames are generated from received signals and stored in a queue. Prior to storage in the receiver queue, some of the data frames are dropped. Data frames are dropped either at a single fixed rate, a dual fixed rate, or a variable rate, generally depending on a communication channel latency. By dropping data frames at the transmitter, the receiver, or both, voice latency due to data frame retransmissions is reduced.

Abstract: Un procedimiento de comunicaciones inalámbricas entre un primer dispositivo (10) y un segundo dispositivo (12) que comprende: transmitir una trama desde el primer dispositivo hasta el segundo dispositivo; recibir un mensaje de reconocimiento negativo, también denominado NAK, del segundo dispositivo, en el que el NAK identifica la trama transmitida; y retransmitir varias copias de la trama en dos etapas en respuesta a la recepción del NAK, comprendiendo la retransmisión: transmitir una primera copia de la trama inmediatamente tras la recepción del NAK; y caracterizado por transmitir al menos una segunda copia de la trama cuando ya no quedan tramas normales ulteriores aguardando transmisión; siendo las tramas normales tramas que no han sido transmitidas aún.

Abstract: A method and apparatus for rejecting a request for call initialization a device capable of multi-mode communications. A user of the multi-mode wireless communication device enters one or more desired communication modes into the wireless communication device, where an indication of the selected mode(s) are stored in a memory. When a page message is received by the wireless communication device, it is examined to determine if a communication mode of an incoming call associated with the page message matches the indication of the selected communication mode(s) as stored in the memory. If a match is determined, the incoming call is accepted by the wireless communication device. If the communication mode of the incoming call does not match the indication of the selected communication mode(s), the call is rejected by the wireless communication device without interrupting the user or a call already in progress.

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 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: Un procedimiento para reducir la latencia de voz en un sistema de comunicación inalámbrica de voz sobre datos, que comprende las etapas de: generar (800) una pluralidad de tramas de datos; descartar (806, 806) una o más de dicha pluralidad de tramas de datos para producir una pluralidad de tramas de datos restantes, en el cual la etapa de descartar una o más de dicha pluralidad de tramas de datos comprende las etapas de: determinar una latencia (802) del canal de comunicación; y descartar (806, 808) cada una de dicha pluralidad de tramas de datos que tenga una tasa codificada igual a una primera tasa de codificación si dicha latencia del canal de comunicación supera un umbral predeterminado; y almacenar (810) dicha pluralidad de tramas de datos restantes en una cola.

Abstract: A method and system for transmitting digital data by extending the sequence numbering range for a selective repeat transmission protocol are described. In accordance with one embodiment of the invention, data frames (70) are transmitted including an eight-bit sequence number (72) and a one-bit retransmit flag (74). The one-bit retransmit flag (74) indicates whether the frame is newly transmitted or retransmitted due to a failed first transmission. Transmit (50) and receive (52) systems each maintain a twelve-bit sequence number referred to as a "long sequence number" comprised of the eight-bit sequence number transmitted with each frame and a four-bit extension. The long sequence number is transmitted within a control frame (82) and the eight-bit sequence number is transmitted within the data frame (72).
