Abstract

Device-to-Device communication is a very important essential feature in PPDR(Public Protection Disaster Relief) communication, but it has not yet been implemented in LTE-based PPDR communication. In this study, we propose a solution to implement the LTE-based domestic PPDR communication network by evolving the terminals into D2D in-band terminals and effectively operating the current PS-LTE terminals and digital radios in the transitional period.

재난통신에서 직접통화는 매우 중요한 필수 기능이지만 LTE 기반 재난통신에서는 아직 구현되지 못하고 있다. 본 연구에서는 LTE 기반의 국내 재난안전통신망의 단말기가 D2D In-band 단말기로 진화하여 구현할 수 있는 방안을 제시하고, 과도기적으로 현재의 PS-LTE 단말기와 디지털 무전기를 효과적으로 운영하는 방안을 제시한다.
