Abstract: |
Self-organizing network(SON) technology is an important tool to improve the efficiency of cellular mobile network operation and maintenance,and also reduce operation expenditure.It has been introduced as a basic function in the initial version of 4G standardization and is constantly developing.The automatic management requirement of SON will be further increased in more complex 5G networks.This paper reviews the basic concept,taxonomy and use cases of SON technology in cellular network,and analyzes the main research methodology of SON.Then it summarizes the research results of academic,standardization organizations and research institutions,with focuse on the latest literatures based on machine learning.It also surveys the status quo of industry application,analyzes the main challenges of SON in future,and points out new research directions. |
Key words: self-organizing network network automatic management machine learning |
