Embodiment Construction

[0048] The embodiments of the present application may be applied to a scenario where a terminal performs handover and roaming in a highway Wireless Fidelity (Wireless Fidelity, WiFi) network, and may also be applied to other scenarios, which are not limited in this application.

[0049] The system architecture of the embodiment of the present application may include a switching device, an access point, and a terminal. The access point may be a WLAN wireless access point or a wireless router, and may be used to provide basic access services and to access the Internet. Access points may include current access points, neighbor access points, and target access points. The current access point may have two neighbor access points, which may be a face-to-face neighbor access point and a back-to-back neighbor access point respectively. The target APs can be face-to-face neighbor APs or back-to-back neighbor APs. The switching device may be an AP, an AC, a switch, a router or an inde...

Abstract

The embodiment of the invention provides a wireless network switching method and device and relates to the field of communication. The packet loss problem when a terminal carries out switching can besolved. The method comprises the steps that a switching device obtains the distance between the terminal and a current access point, thereby determining change trend of the distance between the terminal and the current access point; and if the switching device determines a target access point to which the terminal is about to be switched according to a corresponding relationship between the changetrend and neighbor access points of the current access point, the switching device switches the terminal from the current access point to the target access point. The embodiment of the invention is applied to a scene in which the terminal carries out switching and roaming within an expressway WiFi network.

Description

technical field [0001] The present invention relates to the communication field, in particular to a wireless network switching method and device. Background technique [0002] With the development of technology, wireless local area network (Wireless Local Area Network, WLAN) can be customized high-gain directional antenna, for example, customized 18dBi antenna can make the coverage distance reach more than 600 meters, so that WLAN can be deployed on the side of the highway. A relatively simple and feasible deployment method is as follows: figure 1 As shown, the WLAN wireless access point (Access Point, AP) is placed on the roadside of the expressway, and the user uses a wireless terminal in the car to connect to the roadside AP, and then the AP sends data to the switch or router, so that the The terminal can access the Internet (Internet). On the expressway, the terminal will move rapidly with the high-speed car, so the terminal needs to roam quickly among APs. [0003] T...
