基于无线网络控制器的嵌入式操作系统支撑层设计与实现

Design and implementation of support layer of embedded operating system based on radio network controller

针对无线网络控制器的应用特点给出了一种操作系统支撑层方案,并对其中的调度、定时器、内存管理、I/O驱动和任务间通信等封装机制及实现进行了深入的分析与研究。该方案为无线网络控制器中的ATM传输网络子系统、无线信令子系统、数据库子系统和操作维护子系统的软件提供了一个统一的分布式编程平台和运行平台。通过无线网络控制器产品的实际软件开发实践证明,该方案具有较高的应用价值。

This paper suggested a schema of the operating system support layer oriented to radio network controller （RNC）, and deeply studied and analyzed its scheduler, timer, memory management, I/O driver and internal process communication （IPC） encapsulation mechanism. This schema supplied a uniform distributed programming and running platform to ATM transform network subsystem, radio signal sub system, database subsystem and operation and maintenance subsystem. The software development practice of communication product ZXW10-RNC proves that this schema has high application value.
