| Summary: | 碩士 === 國立高雄應用科技大學 === 資訊工程系 === 97 === Traditionally, people usually get the information by PULL way, but this way is unable to let us obtain the information that we want in the first time. Therefore, PUSH is the best solution of this kind of demand.
Session Initiation Protocol takes the multimedia construction and news transmission ability that exist in the Internet as foundation, providing the conformity pronunciation with other multimedia communication service to achieve the goal of multimedia mmunication protocol. Besides the VoIP application, SIP also suitable in the news conference and immediate news scope. Furthermore, when 3GPP standards organization drew up the standard of UMTSR5, SIP became the main protocol of IP Multimedia Subsystem territory.
The progress and popularization of wireless communication technology have the revolutionary influence regarding people's communication manner. The Push Technology is one of the main information dissemination manners, and cell phone also became the present people’s important tool to obtain the news. This research mainly
establishes a system of information push broadcast. Under the present system unchangeably situation, setting an intermediary service system SIP PUSH DATA SERVER as the foundation coordinates IPPBX and the mobile device that take Session Initiation Protocol (SIP) as foundation to achieve the prompt news pushes broadcasts (PUSH) and the penetration audio frequency control to achieve the prompt receive and response, the application domain is quite widespread and has high value of development.
