| 摘 要： | 在分层蜂窝网络中，为改善网络容量，同时部署宏基站和家庭基站. 本文对该网络中家庭基站的接纳控制进行研究.根据数据业务的到达/离开和用户移动性之间的时序关系，将家庭基站小区接受的数据业务分成4类. 基于部分可观测的马尔可夫决策过程理论，提出针对分层网络的接纳控制分析模型，同时考虑带宽资源利用时间和信令开销.仿真结果证明了所提算法的有效性.

| Abstract: | This paper addresses the case of hierarchical cellular network environment where both macrocell and femtocell are deployed to improve network capacity. The accepted service access to the femtocell is classified into four categories based on the timing relationship between its packet arrival/departure and mobility. An analytical framework is developed for admission control based on partially observable Markov decision process. The admission control decision scheme takes into account both bandwidth resource occupancy time and signaling cost. Simulation experiments corroborate the effectiveness of the developed algorithm. |
