Traffic engineering of trunked land mobile radio dispatch systems

The authors present an investigation of methods for land mobile radio (LMR) channel loading in voice dispatch systems. Queuing models for trunked LMR dispatch systems are reviewed. A decomposition approach is proposed. The decomposed models take into account waiting times both at the system level and at the fleet level, as well as the traffic characteristics of many practical situations, within a consistent methodological framework. Model validation is presented, and some desiderata for monitoring these systems are formulated
