Multimedia Messaging Service (MMS) has been seen as the key application in its entry into 3G services. Recently, the combination of WLAN and 3G wireless technologies will make MMS service more ubiquitous, bringing benefits to both service providers and their customers. To realize ubiquitous 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 MMS Center (MMSC) with many existing components such as SMSC, PPG, HLR, HA, AAA, PDSN, WLAN Gateway, and so on. Based on our proposed platform architecture, we also present seamless MMS delivery scenarios that can't be possible within the current MMS reference architecture. This paper will make a contribution for service providers to provide their customers with seamless MMS service over WLAN and CDMA2000 networks.
