Abstract :
We present a novel model for group speech communications. This model includes timing parameters as well as parameters for spatial distribution and communication topology. Parameter values for this model are derived from the German terrestrial trunked radio (TETRA) trial in Aachen. In order to derive generalized parameter values, we study statistical relationships between model parameters and other measured values. Finally, we apply the new traffic model to a queuing model of a TETRA system and study quality of service (QoS) aspects.
