WiFi access point switching method and device

Abstract

The invention discloses a WiFi access point switching method and device. The method includes the following steps that: a first access point receives terminal position information transmitted by a mobile terminal, and the first access point judges whether the mobile terminal is moving to a second access point according to the terminal position information and adjacent access point position information which is pre-stored locally; when the mobile terminal moves to the second access point, and the first access point confirms that the mobile terminal is closer to the second access point, the first access point obtains the access information of the second access point; the access information is transmitted to the mobile terminal; and when the mobile terminal successfully establishes a connection with the second access point according to the access information, the first access point disconnects the connection with the mobile terminal. With the WiFi access point switching method and device provided by the technical schemes of the invention adopted, the smoothness of a network and reasonable allocation of network resources can be benefitted, and user's experience can be improved.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and device for switching a WiFi access point. Background technique [0002] Wireless Fidelity (Wireless Fidelity, referred to as WiFi) is a technology that can connect terminals such as personal computers and handheld devices (eg tablet computers, mobile phones) to each other in a wireless manner. [0003] The basic units that make up a WiFi network include an access point (Access Point, referred to as AP), a wireless network card (Wireless Network Interface Card, referred to as WNIC) and a wireless bridge. [0004] An AP is a device that can connect to a wireless network or a wired network (that is, Ethernet). It can be used as an intermediary point to connect wired and wireless Internet devices to transmit data and so on. When several APs are running, the transmitted data is connected to another access point through one access point, making the wireless network ex...

AI Technical Summary

Problems solved by technology

[0006] The data transmission rate and signal coverage of each AP device are limited. When there are too many access devices, the communication quality of the access devices will be affected; the signal will attenuate as the distance increases. When the access devices are far away from the AP , it will also seriously affect the communication quality of this device

In the prior art, when a mobile device is connected to a WiFi access point, other access points will be reselected only when the signal disappears and the network is interrupted; if the mobile device needs to reconnect to a new WiFi access point, Need to know the access password of the new access point, which reduces the user experience
