蜂窝网络中切换业务优先的资源调度算法

Handover Priority Based Recource Scheduling Algorithm for Wireless Cellular Network

下一代无线蜂窝网络将提供具有不同服务质量要求的多种类型的业务,同时为了提高频率资源利用率,小区的划分越来越小,切换也越来越频繁。本文在针对多业务类型、切换频繁的蜂窝网络,提出了一种切换业务优先的分层资源调度策略。在调度过程中,优先考虑切换业务的数据包,从而降低了切换掉话率,系统整体性能得到提高。

Multiple services with different QoS requirements will be provided in next-generation wireless cellular networks, simultaneously in order to improve the utilization of frequency resources, the cell is more and more small, and the handover phenomenon is frequent also. For the Multiple services and frequent handover cellular networks, this paper proposes a handover services priority based stratified resouree scheduling strategy , which gives the packets of handoff services higher priority. Analysis results show that the algorithm can reduce the dropping probability, and improve system performance.
