Dynamic channel allocation strategy based on priority and group call service

In order to improve the QoS of group call service,the paper aimed at the importance of group call in trunking communication system.This paper gave an algorithm which was proper for dynamic channel allocation.The group call could borrow channel from common data(not dispatching data) when reaching the threshold(threshold could adjust according to different need dynamic).Simulation results show that,the new algorithm reduces call failure probability of large and high priority group and improves the service utility of system.The improved algorithm is suit for trunking system(DCA).
