摘　　要：以Presence/IM为代表的OTT业务具有实时在线、随时随地沟通的便利性成了移动互联网时代的应用热点.在当前电信标准体系中,Presence/IM实现机制分为SIMPLE和XMPP两大类,但这两类协议制定较早,在流量、功耗及传输上都没考虑移动互联网的特点,本文将在分析SIMPLE和XMPP协议的基础上,提出一种基于订阅/发布模型的移动互联网Presence/IM机制并给出具体实现,并重点阐述多终端同时在线情况时的消息路由机制.最后将本文提出的协议与SIMPLE和XMPP进行了对比分析.Represented by instant messaging of Over-The-Top business with real-time online,communication anytime,anywhere convenience has become hot spot of the era of mobile Internet applications. In the current telecommunications standards system,Presence and Instant Messaging business implementation is divided into two categories： SIMPLE and XMPP,but these two kinds of protocols developed earlier,and on flow,power consumption and transmission didn’t consider the characteristics of the mobile Internet. This article will be based on the analysis of the SIMPLE and XMPP protocol,put forward a model based on subscription and publish of the mobile Internet Presence / IMprotocols,and gives the specific implementation,also focuses on message routing mechanism when multiterminal online at the same time. At last,comparative analysis the proposed protocol with SIMPLE and XMPP.
