| 摘 要： | 随着下一代网络（NGN）各种技术的遥步发展，如何在NGN中使用户不受干扰地享受各种业务将成为未来应用的热点，目前研究的上下史感知（context—aware）技术正好可以实现这个目的，因此，设计一种协议来实现各种基于context的自适应业务是至关重要的。考虑到SIP协议灵活且易于扩展，结合当前一些广泛应用的context—awsre业务，提出了一个基于SIP扩展的CASIP。通过对context的研究，引入context服务器，给出了增强的网络架构，详细阐述了基于CASIP协议的上下文感知业务的实现技术。

| Abstract: | With the gradually development of various technologies for NGN,how to make users receive diverse services with minimal intrusiveness becomes a popular issue in future.The current research on context-aware technology just answers for such issue.The context information is very rich.It can be obtained by various devices.Therefore,it is very important for us to design a protocol based on context information for various adaptive services.Considering SIP which is flexible and extensible together with some context-aware services to have been widely used now,the authors propose a protocol based on the extension of SIP.At first,this paper does some research into the context,secondly,introduce the context server,and then propose the enhanced network framework..Finally,the authors depict the CASIP in details. |
