提出了一种新型的基于业务转移的多小区联合负载均衡方法(MLB).通过多小区协作,MLB在繁忙小区的邻小区范围内执行一跳或两跳业务转移,有效地进行了负载均衡.通过建立基于多维马尔可夫链的MLB理论模型分析了系统阻塞率.仿真结果表明,与现有的负载均衡技术相比,MLB能很大程度地降低热点小区和系统的阻塞率,验证了理论分析的正确性. A new multi-cell joint load balancing method based on service transfer (MLB) is proposed.Multi-cell cooperation enables MLB to perform one-hop or two-hop service transfer in the adjacent cell of the busy cell and effectively load balance. The system blocking rate is analyzed by establishing MLB theoretical model based on multidimensional Markov chain.The simulation results show that compared with the existing load balancing technology, MLB can greatly reduce the blocking rate of hot cells and systems, verifying that the theory The correctness of the analysis.
