    • Provided is a system, method, and computer program for transmitting, across a mobile communication network, the occurrence of silence in a communication channel. The system generally comprises a first Media Gateway (MGW), which could be a transmission control node (first TCN), for executing a silence transmission algorithm, and a second MGW, such as a second transmission control node (second TCN), for executing a comfort noise generating algorithm. One method detects silence in a communications channel and then transmits a network silence indicator (SID). Another method receives the network SID and then produces a comfort noise. The computer program utilizes a query module for detecting a comfort noise production module in a destination MGW, and a network SID transmission module to send a network SID across a PLMN.
    • 提供了一种用于在移动通信网络中发送通信信道中的静音的系统,方法和计算机程序。 该系统通常包括可以是用于执行静默传输算法的传输控制节点(第一TCN)的第一媒体网关(MGW)和诸如第二传输控制节点(第二TCN)的第二MGW,用于执行 舒适噪声生成算法。 一种方法检测通信信道中的静音,然后发送网络静音指示符(SID)。 另一种方法接收网络SID,然后产生舒适噪声。 计算机程序利用查询模块来检测目的地MGW中的舒适噪声产生模块,以及网络SID传输模块,用于跨PLMN发送网络SID。
