The Design And Implementation Of Value-added Services Of Telematics Platform

In recent years, telematics technology and industry rapid development, the rapid increase of the number of vehicles, vehicle mobile Internet successfully meet the people in the process of driving demand for information on the Internet and the rapid development. Domestic and foreign auto manufacturers have proposed their own brand car information and entertainment system, for the owners to provide a variety of value-added services. Because the automobile manufacturers to develop vehicle information system technology is not open. The product can be used in different platform ability is poor, poor compatibility, other developers could not be added to the service provided by the team inside to, and then the platform lack of creativity. Combining with the present situation of the current vehicle information system, design and development of the Android mobile value-added service information system platform architecture based on, integration of all kinds of value-added services and basic services, to provide third-party developers to develop interface is necessary.This thesis mainly studies the design and implementation of a robust, scalable, reusable, and integrated service mobile vehicle networking value-added service platform.. Based on the MVC design pattern to move the car network value-added services platform architecture, and the oriented object analysis OOA and OOD object design oriented to realize the voice group chat, sharing traffic, vehicle remote diagnosis of value-added services. The contents of this thesis are as follows:1 proposed the construction of mobile client and server software architecture. Realize service hierarchical classification, configure flexible management, communication module independent package, extensible service interface design and other important structure optimization. 2 the characteristics of the TCP protocol in mobile environment, the heartbeat mechanism and the upper protocol encapsulation are adopted to guarantee the data transmission stability.. 3 the principle of typical value-added services is analyzed, and several service modes with distinctive features are proposed.. 4. Client software architecture design on the details of the optimization processing: multi activity management, the IOC implementation initializes the control and view customization and encapsulation, NDK achieve large amounts of information push-pull, voice priority management.In this paper, a comprehensive Internet service model, mobile network communication technology and the design idea of the software, combined with mobile vehicle characteristics of value-added services network, realizes the mobile car networking value-added service platform model and architecture design, to provide a comprehensive information service platform for the majority of the owners, provide market access for the majority of businesses, for operators to provide the new profit model.
