Abstract

Channel scanning method and device, storage medium and terminal are provided. The method includes: during scanning of a current channel, determining whether to prolong a minimum channel time of the current channel in a time interval before a probe request frame is sent on the current channel; if it is determined to prolong the minimum channel time of the current channel, updating the minimum channel time of the current channel, or else, maintaining the minimum channel time of the current channel, and on the current channel, contending for channel usage right based on CSMA, and when the channel usage right is acquired, sending a probe request frame, and starting a minimum channel time timer, wherein a timing duration of the minimum channel time timer is set based on the minimum channel time. With embodiments of the present disclosure, channel scanning is optimized and efficiency of the channel scanning is improved.
