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

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.
