摘要：

现有蜂窝移动通信系统支持的业务量相对稳定，不能很好地满足密集用户应急突发业务的需求，在资源综合优化利用方面还存在局限性。无线网络逻辑重构是一种在已有蜂窝系统物理架构上，通过调整或重新配置资源的组织运用方式，以最大限度地提升系统容量的方法。本文首先分析了无线网络重构对于提升蜂窝系统容量的重要性，接着设计了基于SAE的无线网络重构体系架构，在此基础上给出了网络重构的控制方式以及信令实现流程。

Abstract:

The traditional cellular mobile communication network usually supports relatively stable service traffic，can not meet the user needs in the dense user unexpected emergency situation，and still exists limitation in resource utilization optimization. The logical network reconfiguration is a method which re-adjusts and reconfigures the resource allocation scheme based on the existed physical infrastructure of cellular network to maximize the system capacity. This paper firstly analyzes the importance of wireless network reconfiguration for improving the system capacity. Then，the wireless network reconfiguration architecture based on SAE is proposed. Finally，control method and signaling process to support the network reconfiguration is given.

Key words: dense-user area, network reconfiguration, network reconfiguration architecture
