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.
