|Applicants:||HUAWEI TECHNOLOGIES CO., LTD.
|Title:||METHOD AND DEVICE FOR SELECTING CHANNEL|
Disclosed is a method and device for selecting a channel, comprising: obtaining a 5G WiFi channel list corresponding to a current area; calculating an assessment score of each channel belonging to a first channel set in the 5G WiFi channel list, each channel in the first channel set being an outdoor non-DFS channel; and if the highest assessment score of the channels belonging to the first channel set in the 5G WiFi channel list is larger than a first preset threshold, selecting the channel with the highest assessment score as a current working channel. The present application preferably selects a channel with the best quality from outdoor non-DFS channels as the current working channel, thereby avoiding a violation of control domain requirements of some countries in the case that a device works outdoors when an indoor channel is selected, avoiding impacts on user experience caused by that a user terminal that do not support an indoor channel cannot scan an AP, and avoiding the case that, when a DFS channel is selected, the user terminal cannot scan and access the AP during a radar signal detection process of the device.
