Research And Development Of The Key Technologies Of Business Data Exchange For Mobile IPTV Platform

With the gradual evolution of mobile communication networks to the 3G,the mobile IPTV platform,which is able to provide content-rich,high quality multimedia video services to end users,has been the main direction of development of mobile communication Value Added Services.This thesis researches on and further realizes the key technologies of data exchange for mobile IPTV platform,to provide the underlying technology support for the realization of efficient and reliable mobile IPTV platform.Based on the SOAP(Simple Object Access Protocol),this thesis mainly researches on the efficient data exchange technology in heterogeneous platforms for mobile IPTV systems.To sum up,at first this thesis studies the technical elements of the SOAP;on the basis of the analysis and design of mobile IPTV core data exchange processes,and then the thesis researches into mutual service calling technology on the heterogeneous platforms with SOAP,reusable templates based efficient serialization/deserialization techniques and the anti-theft link technique in the SOAP message exchange.These specific contributions of the thesis are as follows:(1)Based on the analysis of some related key technologies in mobile IPTV platform,this thesis analyzes the key technology of data exchange in SOAP,and mainly focuses on the discussion of the principles and elements for both Web services component called technology with SOAP and serialization/deserialization of SOAP messages.(2)Furthermore,this thesis researches and realizes several key technologies of business data exchange in mobile IPTV.It provides an analysis and design of the general architecture and workflow for mobile IPTV,and focuses on the analysis and design of several core data exchange processes and SOAP message exchange interfaces.(3)In addition,this thesis turn to research on the several key technologies of business data exchange in mobile IPTV.The thesis plays an emphasis on the research and realization of data exchange techniques with SOAP on heterogeneous platforms(including the calling and SOAP message chain techniques),reusable templates based efficient serialization/deserialization techniques and the anti-theft link technique in the SOAP message exchange,so as to ensure the performance of SOAP messages exchange while maintaining system reliability.(4)Consequently,the thesis evaluates the performance of the developed SOAP message handling engine-MSOAP.The experimental results show that compared to CXF and Axis,the MSOAP has improve the response time and throughput by using the reusable templates based serialization/deserialization methods.Therefore the MSOAP has met the requirements of mobile IPTV system design.Finally,the thesis shows the applications of the developed mobile IPTV platform.
