Fingerprint type intelligent switching decision method based on fuzzy logic and system

Abstract

The invention relates to a fingerprint type intelligent switching decision method based on fuzzy logic. Switching decision is divided into two stages: the first stage is a switching decision study stage during network deployment and the second stage is a switching decision executing stage during network operation. The first stage comprises the following steps of: carrying out fuzzy treatment on accurate measurements of various switching indicators to form a fingerprint; and the set of fingerprints forms a decision reference knowledge base which is also called a fingerprint base. The second stage comprises the following steps of: carrying out fuzzy treatment on real-time input accurate measurements of various switching indicators; carrying out fuzzy logic matching computation with the fingerprints of the decision reference knowledge base; and switching the decision. The invention also discloses a system using the method. The method and the system disclosed by the invention can be used for transferring a part of treating expense after switching the decision from an operating stage to a network deployment stage, and therefore, the real-time treating expense of the operating stage is reduced and the operating speed and efficiency are enhanced. 本发明涉及一种基于模糊逻辑的指纹式智能切换判决方法，将切换判决分解成两个阶段：第一阶段是网络部署时的切换判决学习阶段，第二阶段是网络运行时的切换判决执行阶段；第一阶段包括如下步骤：对各类切换指示器的精确测量值进行模糊处理，形成一条“指纹”；“指纹”的集合构成判决参考知识库，也即“指纹库”；第二阶段包括如下步骤：对实时输入的所有类别切换指示器的精确测量值进行模糊化处理；与判决参考知识库的“指纹”进行模糊逻辑匹配计算；切换判决。本发明还公开了使用上述方法的系统。利用本发明公开的方法和系统，可以把切换判决的一部分处理开销从运行阶段转移到网络部署阶段，从而降低了运行阶段的实时处理开销，提高了运行速度和效率。
