| 摘 要： | 首先介绍了SIP的基本功能和事务层的处理机制,然后在此基础上提出了基于SIP协议的3G无线视频终端的多线程整体设计方案,并给出了实现流程图。按照会话的建立顺序详细描述了视频通信的建立、会话和终止过程中UAC与UAS的交互过程,并给出了详细的软件设计。该方案充分利用了SIP协议基于IP的设计思想和基于文本的协议解析模式,具有很强的可自定义性和扩展性,软件采用多线程设计,具有很强的功能扩展性。

| Abstract: | The basic functions and transaction disposal mechanism of SIP protocol are descrobed first.Then the overall scheme of 3G wireless video terminal based on multithread method is proposed.Finally,the interaction between UAC and UAS is discussed,and the detailed software design of a SIP wireless video terminal is given in accordance with the order of dialog establishment.The design,with IP-based idea and text-based protocol analytical mode of SIP protocol,is of strong self-defination and expanability,while the ... |
