Abstract

If RCS-e subscribers and SMS subscribers want to exchange instant messages between each other, RCS-e app should know the presence information of the SMS subscribers. However, a RCS-e specification does not have the way to identify the information. This paper propose a software framework that makes RCS-e app can identify the information without having to modify RCS-e app. It describes the call flows between network equipments to manage the information. Also, it defines RCS-e service tags and service tuple for SMS subscribers. Performance evaluation proves that the proposed framework does not add loads to the existing network.

RCS-e 사용자와 SMS 사용자간 메시지를 주고받기 위해서는 RCS-e 사용자가 메시지를 보내기 전 SMS 사용자의 프레즌스 정보를 알 수 있어야 한다. 그러나 RCS-e 표준 규격 상으로는 SMS 사용자의 프레즌스 정보를 조회할 수 없는 한계가 있다. 본 논문은 RCS-e 관련 서버 기능을 일부 수정하여 기존 RCS-e 클라이언트 기능의 수정 없이 SMS 사용자의 프레즌스 정보를 RCS-e 사용자가 클라이언트를 통해 조회할 수 있는 소프트웨어 프레임워크를 제안한다. 이를 위해 각 장비 간 호 처리 흐름을 정의하였으며 SMS 가입자에 대한 RCS-e 서비스 별 Tag 및 서비스 튜플을 정의하였다. 또한 성능 평가를 통해 제안하는 방법이 네트워크에 추가적인 부하를 주지 않는다는 것을 증명하였다.
