Abstract
The third generation (3G) is now enabling faster data rates and various multimedia services. At the moment we are experiencing the fast convergence of fixed and mobile worlds as the penetration of mobile devices is increasing on a yearly basis and soon we will have more than billions of mobile device users. IP Multimedia System (IMS), proposed by 3GPP, is a standard used to design an advanced service platform that can provide a wide range of mobile, multimedia applications on IP infrastructure. From all the IMS components, the User Equipment (UE) is a critical entity for the overall success in the IMS value chain. With this motivation, we have to develop a portable IMS client application on different platforms. With the application, an IMS user could use the services, such as presence, conference, instant messaging, or VoIP, which are provided by IMS. This thesis focuses on the implementation of the IMS Client using a portable library, and presents the details about porting our application from desktop to mobile platforms (Windows Mobile and Nokia Symbian).
