[0030] like figure 1 As shown, the first embodiment of the present invention provides a method for switching a wireless access point, the method comprising:

[0031] Step S101, when the mobile terminal is connected to the first wireless access point, it is judged whether a preset switching condition is satisfied.

[0032] In the first embodiment of the present invention, the mobile terminal may be a smart phone, a tablet computer or the like.

[0033] Step S102, when the preset switching condition is satisfied, the performance index of one or more wireless access points that the mobile terminal has connected to is acquired.

[0034] In the first embodiment of the present invention, the implementation manner of triggering step S102 to acquire the performance indicators of one or more wireless access points that the mobile terminal has connected to will be described in detail later.

[0035] Step S103, selecting a second wireless access point from the one or more wireless acce...

Abstract

The embodiment of the invention provides a wireless access point switching method and a mobile terminal. The method comprises: when the mobile terminal is connected with a first wireless access point, determining whether a presetting switching condition is satisfied or not; when the presetting switching condition is satisfied, obtaining the performance indexes of one or more than one wireless access points having been connected with the mobile terminal; selecting a second wireless access point from one or more than one wireless access points according to the performance indexes of one or more than one wireless access points; determining whether the first switching condition is satisfied or not according to the performance index and the first wireless access point and the performance index of the second wireless access point; and when the first switching condition is satisfied, performing switching processing of wireless connection of the mobile terminal. According to the embodiment of the invention, the wireless access point switching method is able to allow the mobile terminal to rapidly switch to an optimal wireless access point in the environment of multiple wireless access points so as to improve the user internet experience.

Description

technical field [0001] The present invention relates to the technical field of intelligent terminals, and more specifically, to a method for switching wireless access points and a mobile terminal. Background technique [0002] In wireless fidelity (WiFi, WIreless FIdelity) communication, a mobile terminal (STA) realizes Internet access through a wireless access point (AP, ACCESS POINT). Due to the limited coverage of an AP, usually only 50 to 300 meters, The support for terminal mobility is very limited, so it is necessary to perform fast switching between different APs to reduce the network interruption time caused by switching between APs. [0003] The research results show that more than 90% of the handover delay between APs comes from the two phases of the scanning phase and the interconnection protocol (IP, Internet Protocol) acquisition between the Dynamic Host Configuration Protocol (DHCP, Dynamic Host Configuration Protocol) network, which reduces the delay of the sc...
