Embodiment 1

[0022] figure 1 It is a flow chart of a wireless roaming method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of quickly performing Wifi roaming switching on a mobile terminal. The method can be executed by a wireless roaming device, which can be implemented by software and or hardware, and generally integrated in mobile terminals that support wireless roaming.

[0023] Such as figure 1 As shown, the technical solution of the embodiment of the present invention specifically includes the following steps:

[0024] S110. If it is determined that the roaming search trigger condition is met, acquire a current frequency band matching a channel of the current wireless access point.

[0025] In the prior art, based on the roaming search trigger mechanism of Wifi firmware, the period for Wifi firmware to detect the current signal strength is relatively long, which may easily cause the triggering of roaming search not in time. At th...

Embodiment 2

[0041] figure 2 It is a flow chart of a wireless roaming method provided by Embodiment 2 of the present invention. On the basis of the above embodiments, the embodiment of the present invention specifies the specific conditions for triggering roaming search and obtains the current frequency band that matches the channel of the current wireless access point. The process, the process of determining the optimal wireless access point, and the process of roaming handover according to the optimal wireless access point are further specified, and the process of constructing the roaming search channel learning list is added.

[0042] Correspondingly, such as figure 2 As shown, the technical solution of the embodiment of the present invention specifically includes the following steps:

[0043]S210. Determine whether a preset available channel is received, if yes, execute S220, otherwise execute S230.

[0044] In the embodiment of the present invention, effective search for available...

Embodiment 3

[0096] image 3 It is a structural diagram of a wireless roaming device in Embodiment 3 of the present invention, and the device includes: a current frequency band determination module 310 , a candidate channel determination module 320 and an optimal wireless access point determination module 330 . in:

Abstract

The invention discloses a wireless roaming method, device, computer equipment and storage medium. The method is performed by a mobile terminal with a wireless roaming function, and includes: if it is determined that the roaming search trigger condition is met, then obtaining the current frequency band that matches the channel of the current wireless access point; in the roaming search channel learning list, determining that it matches the current frequency band Candidate channels; wherein, the roaming search channel learning list includes the available channels determined according to the channel learning algorithm; among the available wireless access points matching the candidate channels, the optimal wireless access point is determined, and the optimal wireless access point is determined according to the optimal wireless access point. The entry point performs roaming switching. Using the technical scheme of the invention, it is possible to realize fast and accurate wireless roaming switching of terminal equipment.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of wireless communication, and in particular, to a wireless roaming method, device, computer equipment, and storage medium. Background technique [0002] Wireless roaming refers to the situation where a user crosses from one AP (Access Point, access point) coverage area to another AP coverage area during the movement process within the coverage area of ​​the wireless network. [0003] At present, the wireless roaming mechanism of the terminal device is mainly to set the roaming trigger mechanism in the Wifi firmware. When the terminal device is lower than the triggered signal strength or signal quality, it searches for available wireless APs around, and performs roaming authentication after searching for a wireless AP that meets the conditions. Switch and connect to AP. The existing wireless roaming mechanism mainly relies on the signal reception of Wifi firmware and periodic AP se...
