摘　　要：为了提高3G-H.324M终端间的会话建立速度,开发了一种高效地移动多媒体传输协议栈。其中,每个信令实体属于一个类,每个类维护两个独立的状态机。不同的信息驱动不同的状态转换,不同信令实体的不同的类可以独立运行。这样一个3G-H.324M终端能够同时处理两个或者更多的信息,使得多个3G-H.324M终端间能够加速会话建立、进行多媒体通信。同时将该会话建立方法与3G-H.324M中推荐的方法进行了比较,结果显示,新方法更加快速和有效。In order to speed up the session establishment between two or more 3G-H.324M terminals,an efficient mobile multimedia transmission protocol stack is developed based on 3G-324M standards using C＋＋.Each SE is related to one C＋＋ class,which maintains two independent state machines,and state transition is driven by different messages,thus different class for different SE can runs inde-pendently,which means that one 3G-H.324M terminal can process two or more messages simultaneously.Comparison is also made between the presented method and the recommended one in the recommendation 3G-H.324,and comparison result show that the previous method is really better and more efficient than the latter one.
