随着即时通信类应用,诸如微信,阿里钉钉,易信等类似应用在当下移动互联网时代的不断涌现,如何在融合通信的现有体系中高效的支持该类应用,是需要考虑的问题.SIP作为应用层的信令协议,在处理会话类业务上具有优势,但在处理消息类业务上却显得不足.本文在研究和分析SIP的基础上,设计并实现了一种新的SIP服务器系统,可以更好的支持消息类业务的处理.并可通过集群的方式完成多个SIP Broker服务器的分布式部署,具有良好的开放性,为未来业务的发展提供了支撑.%In the Mobile Internet era, many Instant Messaging applications such as WeChat, Ali DingTalk, YiXin and other similar applications have emerged. How to serve for Instant Messaging applications effectively in the current system is a problem to be considered. Session Initiation Protocol is a signaling protocol in application layer. It has advantages in dealing with session, but inadequate in dealing with instant message. This paper describes the design and implementation of a new SIP server system based on the research and analysis of SIP which can deal with instant message better. In addition, SIP Broker can be deployed through the cluster, which can provide supports for future services expansion.
