If the matching is unsuccessful, the next frame of message will continue to be read. If it matches the general call message For success, the count is incremented by one until all messages of the previous day are read. Then read the message of another channel frame by frame and match the message with the general call message. If the matching is unsuccessful, continue to read the next frame of message. If the match with the general call message is successful, The count is incremented by one until all messages of the previous day have been read.
