An improved re-connection priority dynamic multi-thresholdcall admission control algorithm based on QoS
Zhang Libin, Shi Wenxiao · 2009
In this paper, we considered the request of call admission control (CAC) for re-connection and multi-traffic business in order to improve the quality of service (QoS) of system, and proposed an CAC algorithm based on the priority re-connection and multi-traffic business service thresholds, named re-connection priority dynamic call admission control (R-DMCAC), which dynamically adjusts service thresholds according to the system load. Simulation results showed that compared with existing fixed schemes, the proposed scheme can not only guarantee the priority of traffic, but also maintain better performance with the real-time changes of the traffic volume, and improved the QoS of system.
