PDA, 노트북, 팜탑, 데스크탑 등 다수의 단말기에 분산되어 있는 동일한 데이타들에 대해 가장 최신 값으로 일치시키는 것을 동기화(synchronization)라고 한다. 2000년 12월 노키아, 에릭슨, IBM등에 의해 데이타 동기화에 대한 산업계 표준 프로토콜 규격이 발표되었다. 본 논문에서는 SyncML 프로토콜을 구현하고 PIMS(Personal Information Management System) 서비스 데이타 동기화 기능을 지닌 서버의 개발 연구 내용을 소개한다. 서버 구조 설계와 각 프레임 별 기능, 그리고 각 프레임에서의 SyncML 메시지 처리 절차를 제시하였다. 구현한 서버에 대해 적합성 시험과 상호운용성 시험을 수행하였으며 PIMS 서비스에 대해 복수 개 장치 간에 효과적으로 데이타 동기를 수행함을 확인하였다. 또한 세션매니저라는 모듈에서 여러 세션에 대한 정보를 신속히 액세스하도록 관리함으로써, 우리가 구현한 이전 버전 서버에 비해 우수한 성능을 지님을 확인하였다.
