Dynamic Priority Queue Handover Scheme for Multi-Service

Mobile service will be more various and handover have to adapt different quality-of-service (QoS) requirements of all kinds of service in 4G mobile communication systems. In the paper, a dynamic priority queue handover scheme is proposed. With the scheme, a common queue manager (CQM) is appended and the priority in the queue can be changed according to the variety of waiting delay. Furthermore, the resource is graded and reserved, which can insure the access of high priority service. The proposed handover scheme, which is adapted to different QoS requirements, can significantly improve the system performance, and reduce the drop rate and the block rate.
