Design And Realization On GSM/CDMA Dual Mode Mobil Software System

As the mobile communication network, there are a variety of network standard in the mobile device market, especially the application of GSM and CDMA standard most widely used, so for the market demand, the development of practical, economic support GSM and CDMA dual-mode phone particularly necessary. In this paper, one kind of GSM/CDMA dual-mode mobile phone software solutions, the system baseband the MTK main module and Brew Vice module through the UART port to transfer the AT command to control the main and sub-modules interact.This article describes a three-part hierarchical content:The first part of the drive module. Analysis of GSM/CDMA dual-mode software design, how to achieve the UART driver and how to use the UART to achieve the AT communication between the two modules and interface display function of the drive to achieve.The second part is the application module implementation. Analysis of how to achieve calls, text messages, multimedia messages on the private conversation during a call, the implementation process of the conference call to discuss the SMS PDU encoding, Long SMS stitching of multimedia information SMIL language parsing, content parsing implementation process.The third part is the testing and analysis. Analysis by operating file system to simulate the network data transceiver in order to achieve the simulation debugging Catcher Flash Tool and other tools Log analysis of the mobile phone, and the main modules of the black-box testing processes and test cases.The present design solutions of a GSM/CDMA dual-mode software interacts with the module to control the transceiver and control of data between two modules, i.e. via UART. Dual-mode phone calls, messages, data services and other basic functions, and put into practical commercial proved UART communication can be used as a reliable means of communication platform environment, and voice and data services can cross different platforms to achieve.
