Abstract

Recently, as the consumer market of the mobile device is explosively getting bigger and bigger, both of the usability and applicability of the mobile device are also growing rapidly. The customers prefer to transfer data between the different mobile devices and download multimedia data via the wireless connection even wherever they are. The trend of mobile devices also shows the tendency of employing the various connectivity technologies such as Bluetooth, Wi-Fi, W-USB, NFC, and so on in a single mobile device. With this market trend, the importance of the technology associating different devices is getting increased gradually. In this paper, we present how to support the NFC association of the W-USB technology by extending the existing NFC's handover protocol. We also explain the differences between the NFC association and the handover protocol, and propose the method to resolve the differences by extending the handover protocol of the NFC technology. Finally, we describe how to implement the NFC system supporting the W-USB handover protocol.

최근 모바일 장치 시장이 급격히 성장하면서 모바일 장치의 기능성 또한 빠르게 발전하고 있다. 소비자는 모든 환경에서 이기종 모바일 장치간 데이터 전송 또는 무선 인터넷을 통한 멀티미디어 데이터 전송이 가능하기를 원한다. 이와 더불어, 단일 모바일 장치가 블루투스, 와이파이(Wi-Fi), W-USB, NFC와 같은 다양한 connectivity 기술을 채용하는 경향도 보인다. 이와 같은 시장의 흐름에 따라 이기종간 association 기술의 중요성이 점차 부각되고 있다. 본 논문은 기존 NFC handover 프로토콜을 확장하여 W-USB 기술의 NFC association을 지원하는 방법을 다룬다. 또, W-USB 기술의 NFC association 표준과 NFC handover 프로토콜 간의 차이점을 설명하고 기존 NFC handover 프로토콜을 확장하여 이를 해결할 수 있는 방법을 제시한다. 마지막으로 본 논문은 W-USB handover 프로토콜 지원을 위한 NFC 시스템 구현에 대해 기술한다.
