Abstract

In this paper, we have designed and implemented mobile instant messenger which has extensible presence service capability. Most previous work on instant messaging system has some limitation with regard to interoperability and extensibility. To solve these problems, we have employed the presence service architecture of IETF. In order to provide extensible presence capability in the wireless mobile communication, we have employed the presence service attributes which are defined in OMA's IMPS architecture. In particular, we have designed and implemented the presence service libraries for manipulating the presence information in response to user's requirement. finally, we have developed the wireless E-mail service, employing the presence service architecture, to verity the extensibility.

본 논문에서는 확장성 있는 프레전스 서비스를 제공하는 모바일 인스턴트 메신저를 설계 및 구현하였다. 기존의 여러 가지 인스턴트 메시징 시스템은 상호연동성과 확장성에 문제가 있다. 상호연동성 문제를 해결하기 위하여 국제표준인 IETF의 프레전스 서비스 구조를 채택하였다. 그리고 무선 이동통신에서 다양한 새로운 프레전스 기능을 수용하기 위하석 OMA의 IMPS 구현모델에서 정의된 확장성있는 프레전스 서비스 속성을 구현하였다. 그리고 인스턴트 메시징에서 사용자의 임의 설정에 따라 프레전스 정보 표현이 가능하도록 확장성 있는 프레전스 서비스 라이브러리를 설계 및 구현하였다. 구현된 라이브러리를 무선 E-mail 시스템 구현에 적용하여 확장성 있는 프레전스 서비스 기능을 확인하였다.
