A Radio Resource Control (RRC) message transmission method and apparatus for a wireless communication system operating in TTI and acknowledge mode is configured to reduce interruption time by minimizing retransmission times of RRC message. The message transmission method for a wireless communication system includes generating, at a transmitter, a message; transmitting the message two or more times consecutively from the transmitter to a receiver; analyzing, at a receiver, the message transmitted by the transmitter; transmitting an acknowledge message or a negative-acknowledge from the receiver to the transmitter depending on the analysis result; and terminating, at the transmitter, a retransmission process of the message upon receipt of the acknowledgement message.

The present invention relates to an apparatus and method of improving intelligibility of a voice signal. A method of improving intelligibility of a voice signal according to an embodiment of the present invention includes analyzing a background noise signal on a call receiving side, classifying a received voice signal into a silence signal, an unvoiced sound signal, and a voiced sound signal, and intensifying the classified unvoiced sound signal and voiced sound signal on the basis of the analyzed background noise signal on the call receiving side.

An audio/vide bridging (AVB) system using an extended AVB reservation protocol, and a resource reservation method are provided where an AVB system using an extended AVB reservation protocol includes an egress device for transmitting a Generic Attribute Registration Protocol (GARP) or Multiple Registration Protocol (MRP) message comprising an AVB stream identifier or an application stream identifier to a relay device, the relay device for registering the AVB stream identifier or the application stream identifier according to the GARP/MRP message, and transmitting the GARP/MRP message comprising the application stream identifier, to an ingress device, and the ingress device for allocating the AVB stream identifier corresponding to the application stream identifier via the GARP/MRP message comprising the application stream identifier, and transmitting a reservation signal to the relay device.

Extension of audio/video bridging reservation protocol

A system and method of providing a quality of service (QoS) is provided. The method of providing the QoS in the link layer includes receiving, by a stream providing device, minimum and maximum resource requirement information of a stream receiving device; transmitting, by the stream providing device, a reservation message including the minimum and maximum resource requirement information; allocating a resource, by at least one bridge, based on the reservation message transmitted from the stream providing device; and receiving, by the stream receiving device, a stream transmitted from the stream providing device via the resource.

In this application, the invention is a novel heuristic mechanism of working path and backup path reservation for highly utilizable WDM mesh networks, which we call dynamic-network adapted cost selection (DAC-selection) mechanism. One of its characteristics is simple traffic distribution mechanism, and the performance of DAC-selection mechanism is superior to that of Random selection (R-selection) and Advanced Combined Min-cost selection (ACM-selection) mechanism. DAC-selection mechanism provides simple cost function by assigning proper weights to each component of the cost function and the total cost is obtained by just summing up the individual cost. Therefore, it is possible to select a best pair of working path and backup path which consumes least wavelength for reservation.
