An Integrated Services Management Protocol for a Short-Range Mobile Radio Network Using Multiple Access

Future pan-european road-traffic communication networks will use high capacity short-range radio networks with a large number of mobiles. There, many different communication demands arise, especially if we assume a many-services network, where continuous, bursty and/or priorized communication has to be supported. We define an Integrated Services MAnagement Protocol (ISMA-protocol) using multiple access, designed for an efficient use of the limited channel capacity available. The protocol comprises capacity management of direction of movement oriented decoupling of channels via the Decentral Channel Assignment Protocol (DCAP), a packet radio facility using S-ALOHA, handling of priorized emergency warning and in addition provides high capacity channel of 100 kbit/s.
