The authors describe an integrated mobile communications traffic analysis of voice, data and image by a cellular mobile telephone system. They report the results of lost-call and simulation analysis under various traffic conditions. A newly developed universal protocol, an ARQ-based protocol adopted for land data transmission, is considered, along with an forward error corection (FEC)-based protocol which is the adaptive error control protocol adopted for mobile high-speed data transmission. It is found that the integrated mobile communications service can be provided by the present analog cellular system. When used with a 4800-bit/s CCITT V.27 ter modem, this newly developed protocol increases the throughput to 120%. This new protocol can handle data transmission on burst error-prone radio channels if the bit error rate (BER) is less than about 5 × 10 -2.
