    Abstract: The present invention is a novel and improved method and system that prevents RLP3E from generating unnecessary NAKs, thus preventing unnecessary data frame retransmissions. The present invention is efficient, neither delaying the delivery of data frames to the higher data services layer nor delaying the delivery of necessary NAKs to the multiplex sublayer. Additionally, the present invention can be implemented with minimal changes to an existing RLP3E implementation. The present invention is applicable to systems such as cdma2000, W-CDMA, and EDGE, wherein data is transferred using an ARQ (automatic request for retransmission) mechanism, and wherein data packets are sometimes received in an order different from that in which they were transmitted.

    Abstract: Un procedimiento en un sistema de comunicaciones inalámbricas (100) que soporta transmisiones de radiodifusión, presentando el sistema un nodo origen de radiodifusión y al menos un nodo de transmisión de radiodifusión, estando caracterizado el procedimiento porque comprende las etapas de: reconocer un detonante de radiodifusión en el nodo de transmisión de radiodifusión (503, 802); enviar (504) un indicador de radiodifusión desde el nodo de transmisión de radiodifusión al nodo origen de radiodifusión; establecer una trayectoria de transmisión de radiodifusión hacia el nodo de transmisión de radiodifusión desde el nodo origen de radiodifusión (804); enviar un mensaje de radiodifusión a través de la trayectoria de transmisión de radiodifusión al nodo de transmisión de radiodifusión; transmitir el mensaje de radiodifusión desde el nodo de transmisión de radiodifusión (806), en el que el mensaje de radiodifusión no se proporciona por el nodo origen de radiodifusión hasta que el nodo de transmisión de radiodifusión reconozca el detonante de radiodifusión.

    Abstract: A novel method and apparatus for transmitting voice traffic and data traffic over a circuit-switched network and a packet-switched network are presented. A new service option is introduced that allows a circuit-switched network to strip off IP/UDP/RTP header information from an internet protocol packet that may or may not be carrying multimedia payloads. Selectively eliminating the reliability measures in the RLP layer allows the circuit-switched network to reduce the delay associated with data traffic, and thus satisfy the more stringent delay requirements of voice traffic.

    Abstract: A method and apparatus for reducing transmission delay in a wireless communication system that carries packetized voice and data information. Interruptions in the traffic channels cause loss of synchronization between a header compressor and a header decompressor. Rather than transmitting resyinchronization information on the traffic channel, the information dropped by an interruption is re-transmitted on a non-traffic channel in parallel with the traffic channel. At the remote station, information from the traffic channel and the non-traffic channel is reassembled before input into the decompressor. Alternatively, the non-traffic channel can be used to carry overflow information so that a higher average data rate can be achieved than the average data rate of the traffic channel alone.

    Abstract: A method for managing audio during a conference includes receiving, at a first buffer of a mobile device, a first audio stream from a first device associated with a first participant of the conference. The method also includes receiving, at a second buffer of the mobile device, a second audio stream from a second device associated with a second participant of the conference. The method further includes generating a control signal at a delay controller of the mobile device. The control signal is provided to the first buffer and to the second buffer to synchronize first buffered audio that is output from the first buffer with second buffered audio that is output from the second buffer.
