Abstract

Based on analysis of the MGCP protocol, a DSP-based simplified MGCP stack running on LAN IP telephony system is implemented. The simplified MGCP stack adopts layered structure and session state machine, and accomplishes some functions such as individual calling, group calling, full calling, amplifying calling, storage and parse for MGCP messages. The simplified MGCP task is created with μC/OS-II embedded operating system, which shows the character of simple structure, easy debugging, good stability and low cost in practice.

基于DSP的简化MGCP栈的设计与实现
在分析MGCP协议的基础上,实现了一种基于dsp的简化MGCP栈。简化后的MGCP栈采用分层结构和会话状态机,实现了MGCP消息的个人调用、组调用、满调用、放大调用、存储和解析等功能。采用μC/OS-II嵌入式操作系统创建了简化的MGCP任务,在实际应用中显示出结构简单、调试方便、稳定性好、成本低等特点。
