AI Technical Summary

Technical Problem

In WiFi Direct technology, when the sharer's device is off, the device's operating system will automatically sleep on WiFi Direct's service broadcast, resulting in the accessor's device not being able to search for the service broadcast and being unable to access.

Method used

Auxiliary discovery is performed through a cloud server, the device discovery request of the first device is received, and the WiFi information list scanned there is compared with the WiFi information list of the stored second device, to determine whether there is a target device that meets the WiFi direct connection discovery conditions, and to send the hotspot access information of the target device to the first device.

Benefits of technology

It realizes that the sharer's device can still detect and access hotspots normally when the screen is turned off, improves the access success rate, and solves the problem of broadcast interruption of WiFi Direct service.

Abstract

The present application belongs to the technical field of communications. Disclosed are a device discovery method and apparatus, and an electronic device and a storage medium. In the method, a cloud server stores hotspot access information of each second device which serves as a group owner, and Wi-Fi information obtained by means of scanning the surroundings; subsequently, when a first device requests the discovery of a device, a target device meeting a discovery condition is selected from the second devices on the basis of the Wi-Fi information obtained by the first device by means of scanning the surroundings, and Wi-Fi information of the second devices, and the stored hotspot access information of the target device is sent to the first device. The method is a new cloud-assisted device discovery solution, in which a discovery process does not depend on Wi-Fi direct service broadcast, and therefore even if a screen of the target device that shares a hotspot is turned off, the first device can still discover the target device as usual.
