基于IMS移动终端的即时通信联系人列表管理器

The Instant Message Contact list Management Based on IMS Mobile Endpoint

本文主要介绍基于IMS移动终端的即时通信联系人管理器,该管理器主要由XML搜索器、XML解析器、XML管理模块、XCAP通信模块构成。分析联系人列表中联系人的XML片段的定长特性,设计了XML搜索器,实现了节点的快速查找。在XML管理器模块中,以节点路径和消息片段的方式提交联系人修改,减少XML消息传输的字节数,从而提高了消息的传输速率。

This paper will introduce the Instant Message Contact list Management.The Instant Message Contact list Management includes XML Query Model,XML Parser Model,XML Management Model,and XCAP Communicate Model.Through analyzing XML segment of Contact list,we could find the length of the contact in the list is constant,and according to this characteristic we could design the XML Query Model to find node quickly.This paper also implements XML Management Model to modify contact.This Model will put XML node routing and XML segment to the XCAP server to reduce the transport byte quantity of XML message and improve the transport speed for XCAP request.
