| Software of CDMA handset module is studied mainly in this paper,the design of main service functions include phone book and short message are finished on the foundation of its underlayer sustentation platform—DMSS system and its superstratum application software platform—Binary Runtime Enviroment for Wireless.BREW is considered the main universal platform to develop the cell-phone application: Connect the value chain of the mobile communication market , including application program developer , publisher , content provider , equipment manufacturer , operator and user, and a complete set of products and service specially offered to the global wireless data market. This is the criterion that QUALCOMM how to use BREW ,and the key that BREW keeps ahead in this trade. Just because of this kind of BREW idea , publishers , developers, operators and handled device manufacturers only need to invest a little resource and fund,then they can develop and provide new wireless data products and service . BREW has provided BREW client end software, transplant tools , test tool , technical support , traffic development support (OEM relation) ,the specification of the equipment and the relevant advisory service of the products function and identifier. And, withal,BREW can make manufacturer provide their products to the market more quickly, they can self-defining his equipment conveniently and flexibly. The operator can write user interface in BREW upper layer , thus upgrade its interface by wireless.In allusion to the fault of complex code construction,bad transplantable capability,bad extendable capability in traditional software of CMDA handset module,this paper give the software design scheme by using BREW platform.Because of bad reusable capability, maintenance difficultly by using traditional dialog control in BREW platform ,this paper propose the design idea of windows control,solve upwards problem efficiently,reduce the cost of development greatly,enhance technology... |
