Abstract

In this paper, a simplified uplink transmission procedure is proposed for reducing energy consumption and improving lifetime of CIoT devices. In the proposed procedure, the CIoT devices register information on their service and traffic to the networks, and the networks statically allocate pre-defined amounts of radio resources when the CIoT devices have requested permission for their uplink transmissions. This paper provides details of the proposed procedure comparing with those of the current GSM procedure, and defines detailed operations of the devices and the networks for the proposed one. This shows that the proposed scheme can effectively support CIoT services on GSM networks.

본 논문에서는 네트워크로 데이터를 주기적으로 전송하는 CIoT(Cellular IoT) 디바이스의 에너지 소모를 줄이고, 디바이스의 수명을 증대하기 위한 간소화된 상향링크 전송절차를 제안한다. 제안 방법에서 CIoT 디바이스는 네트워크에 자신의 서비스 및 트래픽 특성을 등록하고, 네트워크는 디바이스가 데이터 전송을 시도할 때마다 고정적으로 무선자원을 할당한다. 본 논문에서는 GSM(Global System for Mobile Communications) 표준의 상향링크 전송절차를 기반으로 한 구체적 절차를 제안하고, 제안 절차에서 수행되는 네트워크 및 디바이스의 동작을 정의한다. 이를 통해 본 연구는 GSM 네트워크에서 높은 에너지 소모 요구사항을 가지는 CIoT 서비스를 지원하는 것에 대한 가능성을 보인다.
