Android平台增加专用无线模块的设计与实现

Design and Implementation of Special Wireless Module Added on Androi d Platform

通过研究Android无线框架并借鉴其原生操作系统技术框架,修改原生操作系统RIL框架,实现专用无线模块在Android操作系统下的运行,为终端设备的多样化、专用化提供技术积累。在Android系统中修改相应AT命令及上层framework函数处理流程,实现专用终端从UI调用至底层BP Modem设备正常工作的整个流程,最终实现了专用无线模块的添加,为研制各种专用终端提供了技术前提和技术积累。

This paper studies the Android wireless framework, and modifies the native operating system RIL framework by using for reference its native operating system technical framework. Based on research and modification, the operation of special wireless module is implemented under the Android operating system, and the technical accumulation is provided for the diversification and customization of terminal equipment. The entire work procedure from UI to BP modem is implemented by modifying the AT statements and upper framework functions in Android system. The special wireless modules are added in terminal equipment and worked properly. The technological precondition and technological accumulation are provided for developing various terminal equipment.
