自组织无线网络中的移动负载均衡技术

[摘要] 文章认为基于人工进行的网络优化方法难以适应未来网络发展需要，为此LTE系统引入了自组织网络技术。自组织网络技术涉及网络部署、运行的各个环节，其中移动负载均衡技术是自组织网络技术的一个关键技术。移动负载均衡技术通过用户在不同小区之间的切换实现负载的转移，从而实现负载的均衡分布，提高网络性能。针对很多移动负载均衡算法没有考虑用户的服务质量（QoS）要求，文章介绍了一种保证QoS要求的移动负载均衡算法。

[Abstract] Artificial network optimization does not adequately allow networks to adapt to future developments. In this paper, we introduce self-organizing network (SON) technology in LTE systems. SONs are involved in all aspects of network deployment and operation, and mobility load balancing is a key technology in an SON. The load can be transferred by switching users between different cells. In this way, MLB can distribute the load in a balanced way and can improve network performance. In this paper, a QoS-guaranteed MLB scheme is introduced in detail.
