본 고에서는 5G 시대를 대비한 네트워크의 기술전개 방향성에 대하여 알아본다. 현재의 4G이동통신 네트워크는 이동통신네트워크를 통하여 데이터서비스가 시작되었던 GPRS(General Packet Radio System) 기술을 승계하고 있으나, GPRS구조는 향후 도래할 5G에 대응하기에는 다양한 문제점을 가지고 있다. 또한, 기존의 이동 통신 네트워크는 무선기술 세대별로 별도의 네트워크를 구축해야 하는 문제점을 가지고 있다. 본 고에서는 기존 이동통신 네트워크의 다양한 문제점을 제시하고 이의 해결을 위한 기술전개 방향성을 제시하고자 한다.
