一种状态呈现机制中企业通信录的设计与实现方法

Method for the Design and Implementation of the Addressbook in Presence Mechanism

企业通讯录和状态呈现都是4G电信网络的基础业务.在IMS标准体系中,企业通讯录和状态呈现独立运行,当企业通讯录发生人员或权限变动时,需要客户端手动更改其用户列表并进行状态订阅的更新,这不仅加大了网络消耗和状态呈现服务器的负载,还影响用户体验.针对这个问题,本文提出了一种将企业通讯录与状态呈现融合的方法,该方法通过定时访问企业通讯录,获取客户端权限范围内的用户列表并写入状态呈现服务器,随后状态呈现服务器将该用户列表发送给客户端,客户端即可一次性获得其用户列表及状态的更新.最后,使用SIPHello软终端和抓包工具验证了该方法的正确性.

Addresssbook and presence are all the basic business of the 4G telecom netw ork,in the IM S standard system,addresssbook and presence run independently,w hen personnel or permissions of the addressbook changes,it needs the client to change his userlist manually and update his state subscription,this not only increases the netw ork consumption and the load of the presence server,but also impacts the user experience. To the problem,this article raises a kind of method that makes the addressbook and presence integrate.It gets the userlist w ithin the authority scope of the client by accessing the addressbook regularly and w rites the presence server,then the presence server sends the userlist to the client,thus the client gets his userlist and state updated once. At last,this article verifies the correctness of the method using SIPHello and w ireshark tools.
