Wireless terminal locating method, system and device

Abstract

The invention discloses a positioning method of wirless terminal. AP is accessed into network by the a wireless controller. The positioning method includes the following steps: after the wireless terminal is accessed into the network by the wireless terminal, AC notifies at least an AP near the accessing AP to supervise the wireless terminal; AC receives the information of the wireless terminal which is collected by the neighbor AP, and reports the information to the positioning server; the positioning server positions the wireless terminal according to the information of the wireless terminal. The present invention can make the positioning testing to the wireless terminal by harmorizing a plurality of the APs, to get the enough positioning information, finally realize the accurate positioning of the wireless terminal in the centralizing WLAN network.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a positioning method, system and device for a wireless terminal. Background technique [0002] With the popularization of the network, WLAN (Wireless Local Area Network, wireless local area network) emerges at the historic moment, and it is a kind of local area network that does not need the connection of cable equipment. Wireless local area network uses electromagnetic waves to send and receive data without the need for cable media. It is an important supplement and extension to the wired network, which enables the networked computers to be mobile, and can quickly and conveniently solve network connectivity problems that are difficult to achieve with wired access. WLAN provides a local area network wireless connection service, which can provide high-speed wireless data access in a small area, is one of the more popular technologies in the IT industry, and ...

Problems solved by technology

In the network described above, AP1 can provide the information of wireless terminal 1; in addition, if AP4 can also receive the message of wireless terminal 1, then AP4 can also provide the information of wireless terminal 1; but because AP4 is far away, and AP2 and AP3 work on different channels from the wireless terminal, so neither can provide the positioning server with the information of the wireless terminal for accurate positioning

[0007] In the process of implementing the embodiment of the present invention, the inventor found at least the following problems in the prior art: Although the network has adopted a centralized management method to provide WLAN access services, it cannot make full use of the APs in the WLAN when performing wireless positioning resources for network positioning

Because according to the planning requirements of the WLAN network, adjacent APs need to use different channels as much as possible, so only a single AP can be used to locate the connected wireless terminal, so accurate positioning cannot be performed, which seriously affects the positioning effect of the wireless terminal position
