摘要
频率规划是GSM网络规划和优化中的关键问题,也是难点。如何通过有效的规划设计,使得整个网络各个扇区载频的频点都能够满足要求,保证通话质量,提高系统承载容量是频率规划的核心内容。本文首先简单介绍频率规划的主要问题及之前在此领域所作的研究成果,然后采用图论的分析方法寻找近优的频率规划方案,同时对采用的算法进行了分析和相应的仿真,最后,与之前研究的GSM频率规划方案进行比较,证明其优越性。
Frequency planning is very important and hard in GSM network planning and optimizing. The key problem in frequency planning is to ensure that frequency planning satisfies the need of the whole network, call quality, and improves the whole capacity through effective planning design. This article introduces the problem of frequency planning and the previous research results firstly. Then it proposes graph theory analysis to search better frequency planning methods. At last, it simulates and analysis the proposing algorithm, and compare the algorithm with the exiting GSM frequency planning, ensure that this algorithm is of superiority.
