Embodiment 1

[0085] An embodiment of the present invention provides a method for selecting a serial channel, which describes the scheme for selecting a serial channel from the server side, as shown in figure 1 As shown, the method includes:

[0086] Step S11, the server puts each AP to be channel-configured into a silent state;

[0087] In this step, the introduction of the silent state of the AP can avoid mutual interference in the traditional parallel channel selection process, and provide necessary support for the subsequent AP to correctly and quickly lock the best channel.

[0088] Step S12, the server selects a target AP among the APs, and instructs the AP to close the silent state;

[0089] Step S13, the server instructs the selected target AP to select and switch channels one by one in the scan channel list;

[0090] In step S14, after the selected target AP obtains the available channel with the least interference based on channel switching and migrates to the available channel,...

Embodiment 2

[0093] The embodiment of the present invention provides a serial channel selection method, which describes the serial channel selection scheme from the AP side, as follows figure 2 As shown, the method includes:

[0094] Step S21, all APs to be channel configured are turned on the silent state based on the indication of the server;

[0095] Step S22, based on the instructions of the server, the target AP closes the silent state and switches to each channel in the scanning channel list one by one to obtain the available channel with the least interference;

[0096] Step S23, after the target AP migrates to the available channel, notify the server to select the next target AP among the APs to be channel configured for channel configuration.

[0097] In the above step S22, the way to obtain the available channel with the least interference includes but is not limited to: after the selected target AP switches to each channel one by one, calculate the combined RSSI value of each ...

Embodiment 3

[0181] An embodiment of the present invention provides a server, such as Figure 7 shown, including:

[0182] Quiet state indication module 711, is used for putting each AP of channel configuration to be in silent state;

[0183] An AP selection module 712, configured to select a target AP in each AP, and instruct the AP to close the silent state;

[0184] Channel scanning instruction module 713, for instructing the selected target AP to select channels one by one in the scanning channel list and switch;

[0185] The AP traversal module 714 is used to trigger the AP selection module 712 to select the next target AP among the APs to be channel configured after the selected target AP obtains the available channel with the least interference based on channel switching and migrates to the available channel. Channel configuration until all APs are traversed.

[0186] This embodiment describes the process of assisting APs to complete channel serial selection from the server side....

Abstract

Provided are a serial channel selecting method, device and system, the serial channel selecting method comprising: according to a first indication of a server, a target AP deactivates quiescent state and switches to channels one by one in a scanning channel list, and acquires an available channel with minimum interference, the target AP being selected from various APs requiring channel configuration, and the various APs activating quiescent state according to a second indication of the server; after the target AP is migrated to the available channel, notifying the server to select the next target AP from the various APs requiring channel configuration and perform channel configuration. The technical solution provided by the present invention avoids channel uncertainty during concurrent selection, so that the result of channel selection becomes more precise, effectively reducing on-site wireless interference; in addition, determination is made by respective APs as required, so is simple and easy, and the method is not limited by scenarios, facilitating promotion.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method, device and system for selecting a serial channel. Background technique [0002] WLAN (Wireless Local Area Networks, wireless local area network) technology has completed the leap from 11Mbps of 802.11b, to 54Mbps of 802.11a and 802.11g, and then to the highest physical layer rate of 450Mbps of 802.11N, accompanied by AMPDU (Aggregated MAC Protocol Auxiliary technologies such as Data Unit, aggregated MAC layer protocol data unit), AMSDU (Aggregated MAC Service Data Unit, aggregated MAC layer service data unit), and SGI (Short GuardInterval, short guard interval) make the WLAN wireless service rate faster and faster , Gradually become the expansion and supplement of the wired network. [0003] As users' demand for high-speed wireless Internet access becomes stronger, and notebook computers and mobile phones support high-speed WLAN, WLAN technology is more a...
