Abstract

This paper deals with the analysis of SON (Self Organization Network) technology in LTE networks. SON is a unique LTE feature compared to previous cellular systems UMTS and GSM, and is a cost-effective tool for achieving the best performance in a changing environment. In addition, SON has the function of automating the settings of the network, enabling centralized planning and reducing the need for manual tasks. SON is largely divided into three categories: Self-Configuration, Self-Optimization, and Self-Healing. Each large category has a detailed description, and all the technologies in each category come together to complete the technology called SON. In this paper, we analyzed intensively about ANR among the techniques of Self-Configuration in each of the three categories.

본 논문에서는 LTE 네트워크에서 SON(: Self Organization Networks) 기술 분석을 다룬다. SON은 이전 셀룰러 시스템인 UMTS, GSM과 비교되는 LTE 만의 차별적인 기능이고, 무선 라디오가 변화하는 환경에서 비용 효율적으로 최고의 성능을 도출하는 도구이다. 또한, SON은 운영자가 네트워크의 설정들을 자동화하는 기능이 있으며, 중앙 집중적 계획이 가능하여 수작업에 대한 요구를 감소시켰다. SON은 크게 Self-Configuration, Self-Optimization, Self-Healing의 3가지 범주로 나누어진다. 각각의 큰 범주는 세부적인 기술 내용을 가지고 있고 각 범주의 기술들이 모두 모여서 SON이라는 기술을 완성시키게 된다. 본 논문에서는 각 3가지 범주에서 Self-Configuration의 기술 중 ANR에 대해서 집중적으로 분석하였다.
