Abstract
A communication system connects stationary and second entities via a cellular radio intermediate network. Each such entity has its own network that is separate from the intermediate network, and connects to the intermediate network by a gateway device. A gateway transfers a message while executing protocol conversion under interpretation of a message header. The conversion maintains in the header at least a predetermined subset of the following: Source Address, Geographic Address, Priority Level, Reliability Level, Delay Requirement, Expiry Time and Repetition Time. A critical distinction exists between connectionless and connection-oriented service.
