Study And Application Of Symbian Platform Based On OSGi

More and more applications of Software technology have been found in production environment, which make production more efficient. However, software function updation and easy extension become an important issue in research of software architecture, because of the great challenge by weighted software system and changing demands. As the industry standard of Java modular, OSGi has found its usage in many application systems. When used as the underlying of a software system, OSGi can easily handle the problems brought by requirement changing demands. Each function module is defined as different bundle in OSGi. The bundles is easily reusable and can be installed, started and stopped by software developer and maintainer. The usage of OSGi makes software development more efficient and makes the system more flexible.An embedded environment based OSGi framework is developed in this paper, and a vehicle monitoring and management system based on the OSGi framework is proposed. The client software system contains an OSGi framework and a reusable bundle, while the server software system is a vehicle monitoring and management system based on Eclipse RCP technology. Analysis of OSGi specifications and other popular OSGi frameworks is firstly accomplished and OSGi specifications are resized for J2ME platform and Symbian operating system. Then, a suit of bundles are also developed to meet the demand of the client-side vehicle monitoring and management system. A server-side software system is developed by referencing the features of other vehicle monitoring and management systems. Finally, the client and server software systems successfully passes the software testing. At the end of the paper, a prospect is made for future researches.
