Abstract

The invention is a position service system and method of wireless local-area network (WLAN), and the system has a management server, a locating server and a carriable terminal, uses signal strength data sustainedly sent by the carriable terminal as locating basis, and determines actual position of the carriable terminal and generates and returns corresponding request service content to the carriable terminal for using, according to corresponding coordinate data expressed by the signal strength data in a signal distribution diagram. By the position service based on the signal strength data in the WLAN, it can not only avoid position blind spot but also provide higher locating accuracy.

Description

technical field [0001] The present invention relates to a location-based service (Location Based Service, LBS) system and method thereof, in particular to an application in a wireless local area network environment, using signal strength to locate a portable terminal to provide corresponding service content systems and methods. Background technique [0002] With the rapid development of wireless local area network technology, many wireless local area network applications have begun to emerge accordingly. At present, the most widely used in wireless local area network is wireless Internet roaming, web browsing, sending and receiving e-mail and other applications. These service mechanisms have been developed and matured in the past wired network era, and can be used in today's wireless network era. Or the convenience of wireless use anytime, anywhere. [0003] However, the real wireless local area network application should not stop here. In fact, going further, the wireless...
