The Smart Phone Software Based On Component Technology Development Model

The contradictions between the complexity of the smart phone software and the softwaredevelopment cycle, the limited phone system resources and the multi-function user requirements,and the Internet downloads and the potential security issues, make the traditional softwaredevelopment paradigm a serious problem to the smart phone software development.The emerging of Multimedia Message Services (MMS) marks that China mobilecommunication comes into the multimedia era. The emerging and development of MMS willstimulate the market and technology of the mobile communication. MMS has been widelyrecognized as the pivotal impetus for GPRS and 3G by the Industry, as well as an indispensableservice for the future 4G era.Due to these, this article firstly analyzes the current problems that the smart phone softwaredevelopment confronts. Then it provides a component-oriented technology solution, which canreduce the cost of transition from 3G to 4G dramatically. The author of this article participated thesmart phone software development at Shanghai KORETIDE Co. Ltd focusing on MMS editor ofthe MMS client software. This article introduces the CAR technology into the smart phonesoftware development. The development of MMS client software is based on the embeddedoperating system Elastos with patent. So this article introduces the background knowledge ofElastos and MMS related technologies. Finally this article presents the Design Architecture of theMMS Client and the implementation of the MMS editor that the author accomplished in details.This article is based on the Project of the Embedded Operating System (Project Name: theEmbedded Internet Operating System and the Running Platform spanning OS based on thecomponent technology, SN: 2001AA113400) which belongs to "National key Technologies R&DProgram on Software"of the 863 Program launched by Ministry of Science and Technology of thePRC.
