摘要：A method of transmitting inband signaling messages in a mobile

telecommunications network using SACCH burst. In order to avoid puncturing a fixedamount of bits out of every SACCH burst for inband signaling, the 40-bit FIRE code of the

SACCH is replaced with a shorter CRC code, thereby creating unused bits for carrying themessages. After the SACCH block is shortened, a plurality of dummy bits are insertedinto the shortened block prior to applying a ½ convolutional code to obtain the codedblock. The coded block is further interleaved, reordered and mapped into 4 SACCHbursts. The dummy bits in each SACCH block are then replaced by the inband signalingfor transmission.
