Method and device for switching WiFi access point

Abstract

The invention discloses a method of switching a WiFi access point. The method comprises steps: a to-be-accessed WiFi access point is selected, the selected WiFi access point serves as a target WiFi access point of a terminal, and access to the target WiFi access point is carried out; the target WiFi access point is locked as a terminal WiFi access point; and when the terminal meets a preset switching condition, the locked terminal WiFi access point is relieved, and a to-be-accessed WiFi access point is reselected. The invention also discloses a device for switching a WiFi access point. By adopting the method and the device of the invention, the terminal can use the network normally, and the user experience is improved.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method and device for switching a WiFi access point. Background technique [0002] WiFi (Wireless Fidelity, wireless fidelity) is a technology that can wirelessly connect terminals such as personal computers and handheld devices (eg, Pads, mobile phones) to a network, and is held by the WiFi Alliance (WiFi Alliance). The traditional switching method of WiFi access point (AP, Access Point) is usually, the user enters the corresponding authentication information to connect the terminal to the corresponding WiFi access point, and the terminal according to the currently received WiFi signal strength value of each WiFi access point to decide whether to perform WiFi roaming. The WiFi roaming refers to that the terminal switches from the currently accessed WiFi access point to other WiFi access points, so that the terminal can access the network through the WiFi access poi...

Problems solved by technology

However, due to the different private protocols adopted by ACs or BRASs of different manufacturers, the AC can only report the pre-roaming terminal information to the BRAS it accesses, but cannot pre-synchronize the information to other BRASs or ACs of other brands. Therefore, when a terminal roams between ACs and the terminal roams to another BRAS or an AC of another brand manufacturer, the implementation methods provided by related technologies still have the possibility that the terminal may need to disconnect from the network, wait for the passive logout to succeed, and perform login authentication again process, so that the terminal cannot use the network normally

[0005] To sum up, due to the traditional switching method of WiFi access points, when the terminal can access the network through the already connected WiFi access point, WiFi roaming may also occur, and because when WiFi roaming occurs on the terminal, The terminal needs to go through the process of disconnecting from the network, waiting for a successful passive offline, and re-login authentication, so that the terminal cannot use the network normally, which brings inconvenience to users and reduces user experience.
