一种基于WinCE的UMTS呼叫连接协议实现方案

A Plan of UMTS CC Protocol Implementation based on WinCE

针对通用移动通信系统(UMTS)非接入层呼叫连接协议,提出一种基于WinCE嵌入式系统的实现方案。该方案通过WinCE多线程和互斥体机制架构程序框架,以函数指针数组方式实现有限状态机的状态转移,利用WinCE消息队列机制实现原语和消息的传递,并有效地进行内存管理。实践表明,该设计方案具有编程效率高、实时性强的特点。

To program the call connection （CC） sublayer of UMTS protocol, a plan based on Window CE is proposed. The program, whose frame is composed by multi-thread and mutex, depends on tile message queue for reading and sending the primitive and message with managing memory in a dynamic way. Function pointer array is also applied in realizing FSM.The practice proves that the design has the characteristics of programming efficiently with good real time ability.
