Design And Implementation Of The SMS Module For CDMA Terminal Based On BREW Platform

With the development of mobile communication technology, mobile terminalshave become daily necessities in our daily life. The faster completed development of thephone software, which has better functions and interaction, becomes the mostcompetitive field in mobile phone manufacturer. As a mobile data communicationservice, SMS is always essential function of the phone. As a result, the technology ofdeveloping SMS module has a very good research and application value.In this paper, the background is based on CDMA terminal customization projectwhich use Qualcomm BREW platform. First the paper describes the BREW platformarchitecture, multi-tasking real-time operating system (REX), mechanisms of BREWand management of the applications. Then, according to customer’s customizationrequirements of CDMA mobile communication terminal, produce a detailedrequirements analysis. Next, design the SMS module’s software architecture based onMVC framework. The SMS module is divided into three layers, including the viewlayer, control layer and data layer. View layer is responsible for the display of UI.Control layer is responsible for the view layer and data layer’s interaction. Data layer isthe abstraction for SMS, providing the interface functions for operations to SMS data.Finally, it implements all forms using IWindow mechanism in view layer. It realizeseach function of SMS module using the concept of affair in control layer.It implementsdata interface of SMS in data layer.After the implement of SMS module, it complies the whole module and downloadsinto the phone. According to test cases, the SMS module was tested. The test resultsshow that the SMS module is stable.
