Analysis of Raspberry PI as a presence server / Mohd Safuan Elias

Presence server is a part of services in IP Multimedia Subsystem (IMS) service layer. Presence Server collects, manages, and distributes real-time presence information of users. The server supports SIP protocols to provide the awareness of presence to users. Presence Server includes two major components: Presence Server and Group List Server. This research focuses on Presence Server. Presence Server also provides much richer presence information of each registered entity by integrating the information retrieved from external service providers, such as calendar systems and location servers. The presence server develop to solve several problem such as the efficiency of communication, presence and messaging running on Presence Server and call back notification. So, the general objective in this research are to set up and ensure Presence Server can be running using Raspberry Pi, to evaluate quality of services and to ensure continuity of communication. There are six phases in this research methodology which are information gathering phase, analyzing information phase, design phase, testing phase, data collection phase and documentation phase. In the end of this research, end user will get the benefit of presence services which can get the present and latest user’s information. The presentity will show the information such as communication address, accessibility of terminal and communication status. Observer will get the information in real time and will know how and when they can communicate each other based on the presentity information display.
