Abstract
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.
