Design And Implementation Of Handset Applications On BREW Platform

With rapid progress in mobile communication industry, the third generation mobile communication system will be commercialized soon, while new technologies are already in research, such rapid progress made handset developers hard to choose which network to support. The emergence of handset middleware broke the embarrassment. As handset middleware platforms, BREW and J2ME isolated the differences among networks and various kinds of hardware, made great contribution to the mobile communication industry.First this paper introduced software architecture and cross-compiling development environment on BREW platform, illustrated BREW software architecture from REX operating system to software environment, analyzed software development environment in detail.Then software programming mechanisms on BREW platform were analysed in detail. Introduced Dialog mechanism, elaborated BUIT mechanism with the clue of MVC architecture and compared characteristics between Dialog mechanism and BUIT mechanism.Further more implemented a complex handset scheduler with BUIT mechanism. Requirement specification was introduced, states were modelled, vital techniques were analyzed, problem solving approaches were illustrated and optimization topics were considered.Finally test processes in this cross-compiling environment were introduced.This papter summarized software programming mechanism on BREW platform in detail, summarized optimization and test topics on this platform.
