Abstract


Currently, the mobile network has entered the 3G era, the technical feasibility of the wireless network to provide higher bandwidth for mobile data value-added services. With the popularity of e-mail and SMS SMS development, mobile users have been satisfied with the application of these two have their own shortcomings, came into being with the development of mobile user demand for data services and mobile network technology, multimedia message service. Multimedia Messaging Service (Multimedia Message Service Center, hereinafter referred to as MMS) beyond the limitations of e-mail and short messages SMS (Short Message Service, hereinafter referred to as SMS), to better meet the needs of mobile users. Contrast SMS, MMS business support messages containing multimedia content, the length of the message is no limit, and can provide Internet Email service interworking; contrast Email, MMS is more suitable in a wireless network environment, PUSH business phone push message notification, send a status report and read the reports, and the contents of the multimedia message can be more perfectly displayed on the mobile terminal. The multimedia message service center (Multimedia Message Service Center, MMSC), also known as an MMS relay server, which is the core of the system of the entire multimedia message, the multimedia message to be stored and processed, including the input and output of the message, address resolution, notification, reports, etc., at the same time, responsible for multimedia messages between different MMSC transfer operation. The MMSC can also generate business service use record CDR (Call Detail Record, hereinafter referred to as the CDR) for billing CDRs. , MMSC can be connected to other network and carry out a variety of value-added services. MMS Relay System IP interface, the system connected to the various networks, which support multiple protocols through it. Multimedia message service center business processes, in-depth analysis; master data caching, message queuing technology, clustering technology, on the basis of the flow control mechanism based on the Java language, cross-operating system platform multimedia message service center system, the use of these technologies to the multimedia message service to provide a stable and efficient platform and business security, thereby enabling carriers to improve operational productivity, reduce construction costs and improve customer satisfaction. Thesis the following aspects: (1) the study of multimedia message service, multimedia messaging business process analysis; (2) of the key technologies of the multimedia message service center system analysis, Research cache cluster the application of the technology in the system; (3) the system architecture of the multimedia message service center system design; (4) Design and Implementation of the main module of the multimedia message service center system; (5) of the multimedia message service center were tested, and analyzing the results. Current 3G network construction has been formed. The launch of the MMS business applications greatly expand the use of mobile data services operators provide reliable business growth. With the further improvement of the 3G network, MMS will also be one of its mainstream business. Therefore, the multimedia message service for Chinese carriers to enhance their core competitiveness, continue to make important contributions to maintain a dominant position in the the fierce telecom operator services market competition.
