摘要	This paper gives out a PUB/SUB-based application server software, which aims at improving the coarse granularity of the pushed information in current LBS systems. Taking the advantage of PUB/SUB system's asynchronous, loosely-coupled and multiplex communication mechanism, the server software pushes LBS information with its granularity refined. By combining position information and the PUB/SUB paradigm, users can easily focus on his points of interest. In this paper, three message formats, which are used in the communication between client app and server, are introduced and overall architecture is presented. Furthermore, in order to support indoor and outdoor service, a positioning middleware is also applied. The process of subscription matching utilizes a hash table to speed up the rate. Experimental result shows that the software could offer an efficient service to users. © 2012 IEEE.; This paper gives out a PUB/SUB-based application server software, which aims at improving the coarse granularity of the pushed information in current LBS systems.
