Embodiment Construction

[0019] In order to solve the problems existing in the prior art, the present invention provides a Mesh neighbor scanning method and device, which can enable the AP providing the Mesh service to first determine at least one channel corresponding to the first bandwidth supported by the AP, and then scan the unseen channel in the at least one channel. The channel included in the scanning forbidden list is used as the channel to be scanned; when the AP does not scan the Mesh neighbor from the channel to be scanned, the channel to be scanned can be added to the scanning forbidden list. Compared with the prior art, the present invention can add the channels of the scanned Mesh neighbors that have not been found to the scanning forbidden list, so that when scanning the channel corresponding to the subsequent bandwidth, the channels in the scanning forbidden list can be excluded, thereby Repeated scanning of the same channel can be avoided, so the channel scanning cycle can be greatly ...

Abstract

The invention provides a Mesh neighbor scanning method and device. An AP firstly determines at least one channel corresponding to a first bandwidth supported by the AP, and then channels which are notincluded in a scan forbidden list in the at least one channel are used as to-be-scanned channels; when the Mesh neighbor is not scanned from the to-be-scanned channels, the to-be-scanned channels areadded to the scan forbidden list to avoid repeated scanning of the same channel, so that the channel scanning cycle is greatly reduced and the scanning efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a Mesh neighbor scanning method and device. Background technique [0002] As a new type of wireless network connection, WLAN Mesh (wireless mesh network) gets rid of the shackles of wired networks affected by the environment. APs (Access Points, Access Points) providing Mesh services in the WLAN Mesh network can directly establish wireless connections with each other, and multi-hop wireless links can also be established between distant APs. APs that provide Mesh services can discover Mesh neighbors and establish Mesh links by scanning channels only when they have the same working channel. [0003] In the prior art, according to the regulatory requirements of different regions, different channel resources are available in different regions, and APs in different radio frequency modes, such as 802.11ac, 802.11an, 802.11a, etc., have different working bandwidths. In an exist...
