Abstract
A system and method reduces degradation of voice quality due to Fast Associated Control Channel (FACCH) format signaling between a mobile station and a base station on the digital voice channel. The present invention sends FACCH messages either at the expiration of a timer or during breaks in the speech pattern of a mobile user thereby improving digital speech quality while providing flexibility to implement features and services that require intensive FACCH signaling between a base station and a mobile station during voice conversation. Channel associated signaling messages that are not time-critical are synchronized with speech activity detection.
