현재 디지털 주파수공용통신시스템(Trunked Radio System: TRS)에 대한 표준화가 진행되고 있다. 기존의 아날로그 TRS에 대한 표준화가 무산된 경험이 있는 국내 실정에서는 표준화를 진행하면서 이에 필요한 각 시스템(모토롤라의 IDEN, 지오텍스 FHMA, 에릭슨의 EDACS PRISM)에 대한 특성과 시스템의 구성에 대하여 살펴보았으며, 또한 미국, 유럽 일본에 추진하고 있는 디지털 TRS의 표준화 동향에 대하여 조사하였다. 이들 디지털 TRS에 대한 기술 동향을 살펴보고 디지털 TRS에 대한 표준화에 도움이 되고자 한다.

The Ministry of Science and ICT recently announced its policy direction that involves charging the economic value of radio spectrum for promoting its efficient usage. According to the policy, there will be much efforts to estimate the economic values of various usages of radio spectrum. In this study, the economic value of radio spectrum is estimated for trunked radio system(TRS) by employing the least cost alternative methodology. The proposed methodology estimates the value of radio spectrum according to the cost of an alternative that can be employed for providing the same service. The value of radio spectrum for TRS was determined on the basis of the cost associated with the provision of TRS through the LTE network, wherein the value of radio spectrum for TRS comprises the LTE network cost, capital expenditure for the LTE service, subsidy for the LTE handset, and compensation cost for migration. Results obtained from this study can aid in calculating the economic values of radio spectra for other services and applications.

Radiocommunication systems is very useful method to configure the unified command communication system in case of the disasters. Currently Korea's radiocommunication network against the disasters is operating with TETRA system. This system is very powerful with multifunction to apply in the disaster situation. However, Korea's disaster radiocommunication system is so important to keep and maintain survivability. Therefore this paper study on the alternate systems to TETRA system.
