    • The present invention relates to a message service method and a message service system. The message service method receives a message and a message transmission request from an open service application user and transmits the message to an appropriate transmission infrastructure such that the message arrives at a destination terminal. To achieve this, the message service system includes an open service application server which sends the message and the message transmission request, an open service gateway which reconstructs the message as one of a short message, a WAP Push message and a multimedia message through message analysis, and transmission infrastructures which transmits messages.

    • Provided is a method and apparatus for controlling congestion of a node in an ad-hoc network comprising: classifying a channel state into a busy channel state and an idle channel state and then monitoring the channel state; performing contention for acquiring a channel with neighboring nodes when data to be transmitted is present during the monitoring of the channel state; calculating an available bandwidth on the basis of the channel state when wins the contention; and determining the amount of data to be transmitted on the basis of the available bandwidth. The nodes in the ah-hoc network monitor their own wireless channel state so as to obtain channel contention information, calculate an available bandwidth from the channel contention information, and control a transmission amount on the basis of the available bandwidth. Accordingly, the nodes can avoid excessive traffic which exceeds channel capacity. Channel contention, which is the most immediate and important cause of a decrease in network performance, can be loosened.
    • 提供了一种用于控制自组织网络中的节点的拥塞的方法和装置,包括:将信道状态分类为忙信道状态和空闲信道状态,然后监视信道状态; 当在监视信道状态期间存在要发送的数据时,执行与相邻节点获取信道的竞争; 在赢得竞争时基于渠道状态计算可用带宽; 以及基于可用带宽确定要发送的数据量。 ah-hoc网络中的节点监视其自身的无线信道状态,以获得信道争用信息,从信道争用信息中计算可用带宽,并根据可用带宽控制传输量。 因此,节点可以避免超过信道容量的超量业务。 频道争用是网络性能下降最直接和最重要的原因,可以放宽。

    • Provided are a method and an apparatus for decoding an audio signal. A method for decoding an audio signal encoded by a layered sinusoidal pulse coding scheme using one or more sinusoidal pulses includes decoding the encoded audio signal, setting a smoothing frequency band of the decoded audio signal according to a layer structure of the layered sinusoidal pulse coding scheme, dividing the smoothing frequency band into one or more subbands, and smoothing the decoded audio signal on a subband-by-subband basis. Accordingly, a decoding operation time can be reduced and the quality of a synthesized signal can be improved by variably setting a frequency band to be smoothed, when decoding an audio signal encoded by a layered sinusoidal pulse coding scheme using one or more sinusoidal pulses.
    • 提供了一种用于对音频信号进行解码的方法和装置。 一种使用一个或多个正弦脉冲对由分层正弦脉冲编码方案编码的音频信号进行解码的方法包括解码编码音频信号,根据分层正弦脉冲编码方案的层结构设置解码音频信号的平滑频带 将平滑频带划分成一个或多个子带,并且以逐个子带为基础平滑解码的音频信号。 因此,当使用一个或多个正弦脉冲对由分层正弦脉冲编码方案编码的音频信号进行解码时,可以通过可变地设置要平滑的频带来改善解码操作时间并且可以提高合成信号的质量。
