A Hierarchical Framework for Fine-Grained SIP-Based Location-Aware Integrated System

Abstract

In recent years, wired and wireless network communication technology has progressed at a rapid rate. The evolution of communication technology has accomplished the well-devoloped network environment. The communication speed and bandwidth both increase. As everyone can take advantages of wired or wireless internet services, two issues should be taken into consideration: what kind of information is to be provided to internet users and how to provide active or passive information services. Obviously, the location of users and the characteristics of the access network are very important. Therefore, this study focuses on the acquisition of the information of the user’s location and the network environment. In this study, the system architecture was suggested to acquire the location information of the user’s location in SIP environment. Based on the information, the active or passive intelligent services can be provided. Hopefully, this study can be a pioneer in development of the intelligent campus information system.
