Abstract
An apparatus and method for processing a corrupted frame. The corrupted frame is analyzed to ascertain whether the rate can be determined. If the rate can be determined, steps for identifying the rate are executed. After the rate is identified, the method scans the corrupted frame by checking the MM/TT/TM or MM/FM bits (depending on the radio configuration) to determine whether signaling is present in the frame. If the scan finds potential signaling information, the BTS informs the transcoder of the frame rate, that signaling is present in the frame and that the outer CRC failed. The transcoder attempts to recover the signaling information based upon the inner CRC and discards the bearer information. If the signaling message is spread over multiple frames, the entire frame is discarded to avoid confusion when the signaling message has to be reassembled. The entire frame is also discarded if the inner CRC fails.
