As a private mobile communication system, The digital trunkingmobile communication system was boomed in 1990's, and before this, the appliedprivate mobile communication systems in market are almost the analog systemwith analog voice and digital signalling. And there are no data referring to thesystem design and parameters chosen. It includes the wireless channel accessalgorithm of the mobile terminals, single base station capacity in large regional networks, link designing schemes between the switching control center and basestation as well as the study of the service quality for the multiple traffic. Theseindispensable parameters in design a digital trunking communication system arestudied in this dissertation and some instructive achievements can be got. To provethe correction of the theoretical study, the result was tested with the popularsystem of pan-European digital trunking communication system.
