Improving Handover Performance in Wireless Mobile Networks
In this paper, the authors propose an enhanced packet scheduling scheme to favour UEs that experienced HandOver (HO) in wireless mobile networks. The main idea of the proposed scheme is not only prioritized the HO connections at the CAC level but also prioritized the HO connections at the scheduler level. At the CAC level, a guard code scheme favours HO calls over new calls. At the scheduler level, a Packet Scheduler based-HandOver Class (PS-HOC) scheme makes use of the elapsed time of HO connections to classify the HO requests into prioritized HO and non-prioritized HO calls. Further, PS-HOC sorts the connections based on their delay sensitivity and their channel quality.
