Abstract
With the rapidly growing Internet and the evolving wireless communications, both E-Mail and SMS have been widely used for messaging in fixed and wireless networks respectively. SMS and EMS have been very popular in the 2nd Generation (2G) of wireless communication systems, but with limited contents; moreover, E-Mail does not take advantages of mobility in wireless networks, neither is capable enough to fulfill the present and future demands of wireless messaging. MMS evolved from SMS, which allows mobile device users to send and retrieve messages with a rich combination of media elements, compared with SMS and EMS, such as text, color image, audio and video. Essentially, these messages are transferred through certain message centers. In this thesis, we design and implement one Multimedia Messaging Service Center according to MMS elements and interfaces as defined in 3GPP MMS-related standardizations. Besides already having MM transferred; moreover, this designed MMS Center can interoperate with other external servers and thus enables the integration of external messaging systems. The interworking with theses heterogeneous messaging systems may be available. Furthermore, the handling of messages may be based on user settings in the user databases while providing personalization and customization of services.
