Abstract

Concurrent with the more widespread usage of smart devices, mobile users' desires are becoming much more complex. Most IT experts insist that smart devices should have additional functions to satisfy these requirements. In particular, research has concentrated on LBS (Locationbased Service), because it is considered one of the most common mobile service types. Generally, Wi-Fi has a critical limitation for use for LBS services, because it requires new network connection points whenever its location (Network Zone) changes. Unfortunately, GPS also has a systematic problem in providing LBS service in the indoor environment, because of its inaccuracy in processing data. So, to redress these limitations, iBeacon technology has been designed, and is currently used for LBS service instead of Wi-Fi or GPS. By using iBeacon, which is based on Bluetooth 4.0 LE technology, we propose a M-SAS (Mobile-Subway-Alarm-Service System) that could accurately and timely provide its users with various mLBS (micro LBS) services, such as current user location, and subway arrival time.

현재 스마트 디바이스의 활용도가 높아짐에 따라 사용자의 요구는 점점 복잡하게 되어가고 있다. 대부분의 IT 전문가들은 이러한 요구사항을 만족시키기 위해서 추가적인 기능들이 추가되어야 할 것으로 주장한다. 모바일 서비스 형태의 대부분이 위치 기반 서비스(LBS: Location-based Service)를 고려하기 때문에 이는 특히 중요한 연구로서 집중되고 있다. 일반적으로 Wi-Fi 기술은 위치 즉, 네트워크 존(Network Zone)이 변경됨에 따라 새로운 연결을 요구하기 때문에 위치 파악이 제한적일 수밖에 없다. 또한, GPS는 부정확한 실내 데이터를 가지기 때문에 실내 환경에서 LBS 서비스를 제공하는 것은 여전한 시스템적인 문제가 있다. 따라서 이러한 한계를 극복하기 위해 iBeacon 기술이 설계되고 Wi-Fi 혹은 GPS 대신에 LBS 서비스를 위해 사용되고 있다. Bluetooth 4.0 LE 기술 기반 iBeacon을 사용하여 우리는 현재의 사용자 위치와 지하철 도착 시간을 활용할 수 있는 다양한 mLBS(micro LBS) 서비스를 정확하고 알맞게 제공하기 위한 M-SAS(Mobile-Subway Alarm Service System)을 제안한다.
