摘要: 为了实现无线蜂窝网的区域化节能，该文基于自主管理技术提出了区域化的自主节能管理机制(AESMM)。首先分析了无线蜂窝网的节能模型，之后提出AESMM流程。针对AESMM中核心问题，提出了区域化双基站补偿法和智能自主覆盖优化算法，以在保证区域覆盖率的同时实现区域节能的最大化。该机制在WCDMA/HSDPA 城区场景中进行了仿真，并与参考文献中的两种算法进行对比，验证了该机制能够在保证有效业务质量和良好的覆盖情况下，节约区域约17%的能量，实现最大化的节能。Abstract: An Autonomic Energy-Saving Management Mechanism (AESMM) based on autonomic management is proposed for saving energy in wireless cellular networks. Energy-saving model is analyzed firstly, and then procedures of AESMM are introduced. As two key issues of AESMM, regional BS opposite-pair compensation method and autonomic intelligent optimization algorithm for coverage compensation are proposed. Objective is maximizing regional saving energy and meanwhile guaranteeing regional coverage and service quality. AESMM is simulated under WCDMA/HSDPA scenario. Comparing to other two methods adopted in the references, results show that AESMM can save maximal energy (about 17% of regional energy consumption) while keep regional coverage and service quality acceptable.
