Windows CE6.0嵌入式操作系统新增了对移动通信更强大的支持。这篇文章实现并优化了基于Windows CE6.0操作系统、Monahans310处理器、SIM300D芯片的电话系统。不同于通常的直接在应用程序中发送AT命令以实现电话功能,此设计基于RIL架构,屏蔽底层设备硬件细节。这篇文章利用TAPI实现电话功能,并引入电话管理层管理电话系统、封装TSP消息,使上层应用和底层硬件设备完全剥离。采用此方案实现的电话系统功能稳定、可移植性高。
Windows CE6.0 embedded operating system has added more powerful support for mobile communications. This article implements and optimizes the phone system based on Windows CE6.0 operating system, Monahans310 processor, SIM300D chip. Rather than sending AT commands directly in the application for phone functionality, this design is based on the RIL architecture and shields underlying hardware details. This article uses TAPI to implement telephony features and introduces a telephony management-managed telephony system that encapsulates TSP messages to completely strip the top-level applications from the underlying hardware. The telephone system implemented with this solution has stable functions and high portability.
