Abstract

The invention discloses a method and system for real-time positioning of a WiFi terminal. The PORTAL server receives the HTTP access request sent by the WiFi terminal, and identifies the access server accessed by the WiFi terminal according to the IP address of the WiFi terminal. , and the access server port and VLAN information returned by the access server, determine the wireless access point AP device that the WiFi terminal accesses, and realize the real-time positioning of the WiFi terminal according to the deployment position of the AP device. The method and system of the present invention can reversely identify the uplink of a WiFi user, and use the logical link information composed of the three elements of the access server, the access server port, and the AP service VLAN to communicate with the AP devices on the entire network. The unique corresponding relationship established can locate WiFi users in real time and accurately, without installing any application software on the terminal, and has no special requirements for the bearer network. Therefore, it has strong applicability and can effectively improve the WiFi positioning capabilities of telecom operators and their related services. coverage.

Description

technical field [0001] The invention relates to the technical field of mobile positioning, in particular to a method and system for real-time positioning of a WiFi terminal. Background technique [0002] The user spatial location positioning service in the field of mobile communication has been widely used in social and economic activities such as transportation, mobile e-commerce, and emergency rescue, and has become the most promising mobile Internet service at present. The currently commonly used GPS (Global Positioning System) positioning service is limited by its technical principles and is only suitable for outdoor open areas such as deserts and oceans. It is not effective for common application scenarios in cities such as indoors and densely populated areas. [0003] With the construction of wireless broadband cities and the popularization of user WiFi terminals, WiFi networks have been widely deployed in urban indoor and outdoor business hot spots. WiFi technology h...
