摘要
针对目前CSCL系统在支持“个性化”与移动性等方面灵活度不够的问题,结合信令控制协议SIP具有灵活、方便、易扩展的特性,综合运用CSCL的原理、数据库技术、多媒体通信技术,研究并设计了一种基于SIP协议的CSCL模型系统,着重讨论了该系统的会话模式设计、体系结构设计及其资源层、服务层、SIP服务器与SIP终端的设计.
In allusion to the insufficient of the flexibility of the CSnd scalable characteristic of SIP protocol as a signal control protocol, synthetically using the CSCL principle technology, database technology and the multimedia communication technology, it was studied and designed a SIP-based CSCL model system. It was discussed the design of conversation model, the systemic structure of the CSCL system, the design of its resource layer, SIP server and SIP terminal.
