Abstract

PS-LTE, which is mentioned as a next-generation disaster network technology, is a communication technology that supports communication between terminals and group communication necessary for public safety communication based on LTE technology. Currently, Korea is establishing a PS-LTE network construction plan and installing a PS-LTE system. The world is currently making a lot of efforts to build a disaster network system using PS-LTE. However, due to the characteristics of the closed network that only the related persons can access, it can not be operated like the existing commercial network, so it is necessary to build a new network. And it is expected that many periods and costs will be required. In order to establish a disaster safety communication network efficiently, it is necessary to consider the linkage of PS-LTE network, which is newly constructed by complementing the problems such as security and access priority to existing LTE network rather than unconditional new construction.

차세대 재난망 기술로서 언급되고 있는 PS-LTE는 LTE 기술을 근간으로 공공안전 통신에 필요한 단말 간 통신, 그룹통신 등을 지원하는 통신기술이다. 현재 우리나라는 구축계획을 수립하여 PS-LTE 시스템을 설치하고 있으며, 국제적으로도 PS-LTE를 활용한 재난망 시스템 구축에 많은 노력을 하고 있다. 그러나, 관련자만 접속할 수 있는 폐쇄망의 특성상 기존 상용망과 별도 구축이 필요하며 많은 기간과 비용의 소요가 예상된다. 효율적으로 재난안전통신망을 구축하기 위해서는 무조건적인 신규 구축보다는 기존 LTE망에 보안 및 접속우선권 등의 문제를 보완하여 신규 구축하는 PS-LTE망의 연동을 고려해야 할 것이며 이를 위한 사전 검토가 매우 필요하다.
