Abstract
A telecommunications system and method for minimizing interruptions to voice transmissions due to the transmission of overriding control signals is disclosed. Since FACCH and other control signals replace or block-out speech data, the quality of speech transmissions deteriorates the longer the control transmission. Through modifications to the FACCH protocol, lengthy sequential FACCH or other control transmissions are divided into a plurality of discrete control segments, which are transmitted non-sequentially throughout a speech transmission, and queued at the receiving end. After receipt of all of the control segments, the original control message is reconstructed and forwarded for processing.
