Title:
METHOD AND DEVICE FOR ESTABLISHING WLAN LINK
Document Type and Number:
WIPO Patent Application WO/2019/001568
Kind Code:
A1
Abstract:
A method and a device for establishing a WLAN link. The method comprises: a first network device using an initial bandwidth to broadcast a probe request; detecting whether a probe response corresponding to the probe request and sent by a second network device has been received and, if the probe response has not been received, using an adjusted bandwidth to broadcast the probe request; and then beginning to re-execute from the aforementioned step of detecting whether a probe response corresponding to the probe request and sent by second network device has been received, the adjusted bandwidth being a smaller bandwidth than the previously used bandwidth; and, if a probe response is received, then establishing a WLAN link with the second network device, the bandwidth of the WLAN link being the bandwidth used when receiving the probe response. The solution provided in the embodiments of the present application uses a smaller adjusted bandwidth to re-send a probe request when a probe response corresponding to the probe request has not been received, and thereby expands the scope of the probe, ensuring successful establishment of a WLAN link.
