摘要:

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.

关键词: 蜂窝网, 多小区联合负载均衡, 阻塞率, 业务转移

Abstract:

A new traffic transferring based multi-cell load balancing (MLB) scheme is proposed. By multi-cell cooperation, MLB carries out one or two hops traffic transfer among the busy cell and its neighbors and achieves load balancing effectively. A multi-dimensional Markov chain based model is also built for MLB to analyze the system call blocking probability. Simulation verifies that MLB decreases hot cell and system call blocking probabilities greatly comparing to available schemes.

Key words: cellular networks, multi-cell load balancing, call blocking probability, traffic transfer
