Dynamic channel allocation strategy based on priority and group call service
一种基于优先级组呼业务的动态信道分配策略

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 datanot dispatching data when reaching the thresholdthreshold 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 systemDCA .
