LBS 기술은 현재까지 이동통신 기술의 발전 및 측위 기술의 고도화를 통해 다양한 측위 인프라를 기반으로 발전되어 왔다. 측위 환경 및 방식에 따른 다양한 LBS 솔루션이 공존하며 대부분의 표준 단체에서 새로운 기술을 개발하고 있다. 네트워크 기반 측위 기술은 쉽게 접근할 수 있는 인프라임에도 불구하고 상용 수준에서 만족할 만한 성능을 보이고 있지 않다. 따라서 본 논문에서는 네트워크 기반 측위의 중요성 및 범용성을 감안하여 관련 기술 및 표준화 동향을 살펴보고, 현재의 기술 수준을 향상시키고 고정밀 위치인지를 가능하게 하기 위해서 해결되어야 할 과제에 대해 고찰해 보도록 한다.
