MMS has been seen as the key application in its entry into the 3G mobile markets. Furthermore, the combination of WLAN and 3G wireless technologies will make MMS service more popular, bringing benefits to both service providers and their customers. To realize seamless MMS service over WLAN and CDMA2000 networks, we design and implement new platform architecture by reusing the existing standards and network elements at the same time. We employ loose coupling approach and Mobile IP approach to propose new platform architecture, interfacing MMSC with many existing components. Based on our platform architecture, we also present seamless MMS delivery implementations that can't be possible within the current MMS reference architecture. This paper will make a contribution for service providers to offer their customers with seamless MMS service over WLAN and CDMA2000 networks.
