上下文感知业务在移动网络中的应用

随着移动计算和网络的技术的快速发展,通信业务也随着这些变化而改变。当人们之间互相作用的时候,他们之间隐含的使用上下文信息来推断和解释他们的实际情形。和人类相比IT设备不能很方便的使用上下文信息来交互作用。一个业务能够上下文感知,那么它就必须能够透明的适配它们的行为到用户的上下文。在移动网络中,上下文感知业务的应用存在着许多的挑战,在这篇文章中,笔者提出了一种框架概念配置在移动网络中的上下文感知业务的应用。还描述了一个上下文感知消息业务(Context-Aware Messaging Service,CAMS)说明这个框架。

The application of context - aware service in mobile networks

As mobile computing and network technology being developed more and more quickly,communication services should change accordingly.When people interact with each other,they implicitly make use of context information while intuitively deducing and interpreting their actual situation.Compared to humans,IT infrastructure cannot easily take advantage of context information in interaction.For a service to be context-aware,it must be able to transparently adapt its behavior to the user's context.There are many challenges of context-aware service in mobile networks.In this article,the writers propose a conceptual framework for deploying context-aware service application in mobile networks.A context-aware messaging service has been realized,which is also presented in this paper.
