为了减轻小区中断引起的性能下降，本文提出了一种集中式小区中断补偿管理机制和相应的工作流程。提出了一种基于自主粒子群补偿算法（APSCA）的补偿方案生成算法。仿真结果表明，该算法能有效解决中断引起的覆盖问题。在模拟场景中，几乎98.3%的用户将被丢弃，否则将由周围的小区服务，并且补偿小区的阻塞概率仍然保持在可接受的水平上。
To mitigate the performance degradation induced by the cell outage, in this paper, a centralized cell outage compensation management mechanism and the corresponding workflow are proposed. Then a concrete algorithm named autonomic particle swarm compensation algorithm (APSCA) is proposed to generate the compensation scheme. The simulation results show that the proposed APSCA is effective to resolve the coverage problems induced by the outage. In the simulation scenario, almost 98.3% users that would otherwise be dropped will be served by the surrounding cells, and the block probabilities of the compensating cells are still kept on the accepted levels.
