Abstract: En una modalidad particular, se describe un método que incluye recibir un mensaje de realimentación en un transmisor, el mensaje de realimentación incluye una indicación de una magnitud de congestión y un índice sostenible de transmisión de datos en un receptor. El método también incluye determinar un índice de descongestión y un tiempo de descongestión basándose por lo menos en uno del índice sostenible de transmisión de datos y la magnitud de congestión cuando la magnitud de congestión cumple con un valor de umbral. El método además incluye enviar datos en el índice de descongestión desde el transmisor hasta el receptor durante el tiempo de descongestión. El método además incluye ajustar un índice de transmisión de datos en el transmisor para el índice sostenible de transmisión de datos después de que se finaliza el tiempo de descongestión.

Abstract: Systems and methods for adapting a de-jitter buffer to conform to air link conditions. An air link characteristic may be detected before that characteristic begins to affect packet delivery, such as by slowing or speeding delivery delay at a subscriber station. A receiver-side de-jitter buffer, which adds delay to received packets, may adaptively adjust its size based upon the detected air link characteristic, such that the de-jitter buffer is appropriately sized for anticipated data packets before they are received at the subscriber station.

Abstract: Adaptive De-Jitter Buffer for Voice over IP (VoIP) for packet switched communications. The de-jitter buffer methods and apparatus presented modify the playback of packets dependent upon whether silence periods are detected inter-sentence or intra-sentence to optimize voice quality in a communication system. In one example, a de-jitter buffer determines the length of at least one silence period associated with a plurality of received packets and determines a time to transmit a portion of the packets based on the determined length of the silence period. In another example, a silence characterizer unit performs this function.
