Selection system and selection method of wireless network access point

Abstract

The invention discloses a selection system and a selection method of wireless network access point. The selection system comprises user equipment and a central server, wherein the user equipment is used for transmitting the user equipment information and the information of the accessible wireless network access point to the central server for querying, then, receiving the querying result of the central server, selecting the access point with optimal network connection data as a linkage target from the querying result, and sequentially building linkage; the central server is used for receiving the user equipment information and the information of the accessible wireless network access point, and for each accessible wireless network access point, searching the historic record data matched with the receiving signal strength indication and the application program transmission type of the corresponding wireless network access point in a historic usage database of the central server, using the historic record data and the searching result, and returning back the searching result to the user equipment. The system and the method can be used for realizing low-overhead and low-delay selection of the wireless network access point.

Description

technical field [0001] The invention relates to the field of wireless local area networks, in particular to a selection system and a selection method of a wireless network access point. Background technique [0002] Wireless Local Area Network (WLAN for short) is a local area network that uses radio waves instead of any wires or transmission cables to connect as a data transmission medium. The backbone network of the wireless local area network usually uses wired cables, and users of the wireless local area network connect to the wireless local area network through one or more wireless network access points (Wireless Access Point, AP for short), so as to access the Internet. figure 1 It is a schematic diagram of the architecture of a wireless local area network. Such as figure 1 As shown, multiple wireless network access points 12 are stored, and the user equipment 11 can select different wireless network access points to connect to the central server 13 . [0003] With t...

Problems solved by technology

However, this type of method has a disadvantage that the measurement overhead is very large. Because each access point needs to be used to download relatively large test data from the remote server, it causes unnecessary network traffic overhead, and because the download takes time, the user needs a long time. It takes tens of seconds to test the optimal wireless network access point, which is unacceptable for ordinary users

[0009] It can be seen from the above that the selection system and selection method of wireless network access points in the prior art have problems such as large measurement error, high overhead, and high delay.
