In order to simplify the process for establishing Mesh link between FatAP, the embodiment of the invention provides a kind of Mesh links to build
Cube method, device, fat AP and storage medium.
It is introduced in the following, being provided for the embodiments of the invention Mesh link establishing method first.
Mesh link establishing method provided by the embodiment of the present invention can be applied to the FatAP in Mesh network, specifically
, it can be the AP in WDS (Wireless Distribution System, wireless distribution system), WDS is Mesh network
A kind of application, as shown in Figure 1, by two independent local area networks of Mesh link connection between AP1 and AP2, and at them
Between provide data transmission.FatAP in Mesh network can provide Mesh service.It realizes provided by the embodiment of the present invention
The mode of Mesh link establishing method can be at least one in the software, hardware circuit and logic circuit being set in FatAP
Kind.
As shown in Fig. 2, a kind of Mesh link establishing method provided by the embodiment of the present invention, may include steps of:
S201 selects a channel from available channel, and the channel selected is determined as odd-job channel；It will face
When working channel as current sounding channel, the broadcast probe request message on current sounding channel.
For the Mesh network of AC+FitAP (thin AP) network environment, AC can be MPP (Mesh by modification role
Portal Point, Mesh Ingress node) AP working channel, other roles (MP (Mesh Point, Mesh node) and
MAP (Mesh Access Point, Mesh access node)) AP be arranged to automatic channel (that is, by AP oneself from available channel
Middle selection working channel), the working channel change of Mesh network can be realized.But for being similar to FatAP network environment
For Mesh network, each FatAP needs individually modification channel configuration, leads to the process that Radio Link is established between FatAP
Too complex.
In embodiments of the present invention, FatAP is configured to automatic channel, FatAP after an initial power up, can be supported from itself
Available channel (for example, can be embodied in a manner of available channel list) in select one channel as odd-job channel, it is sharp
Regular traffic (such as terminal access service etc.) processing is carried out with this channel.At the same time, this channel is also used as first detection
Channel (that is, current sounding channel), broadcast probe request message, starts to detect whether to exist to can establish Mesh on this channel
The fat AP of link.It is subsequent if there is and if being successfully established Mesh link, fat AP will continue to monitor simultaneously in this multi-channel operation
The channel quality of this channel.
It is subsequent that this channel can be considered as to unavailable channel when the channel quality for monitoring this channel is poor, for example, can incite somebody to action
This channel is removed from available channel list, later, is disconnected Mesh link, can be executed since S201 again；It can also be straight
It connects and is switched on the preferable channel of channel quality (as odd-job channel), start to execute to broadcast on current sounding channel and visit
The step of surveying request message；It can also be directly switch on the preferable channel of channel quality, before switching channel, can notice
The fat AP in the opposite end of Mesh link allows the fat AP in opposite end to be also switched to the channel that will switch, so as to after switching channel, as early as possible and
The fat AP in opposite end establishes Mesh link again, shortens detection time again.
It should be noted that the odd-job channel of each fat AP selection may be identical, it is also possible to different when initial.
S202 is rung on current sounding channel with detection if receiving detection response message in default detection duration
The fat AP negotiation in the source of message is answered to establish Mesh link, and after being successfully established Mesh link, the probe requests message of going off the air,
It is carried out wireless communication using current sounding channel and the fat AP in source.
After a length of FatAP issues the probe requests message when default detection, between the maximum time for receiving detection response message
Every usually by shorter (such as the 50ms) of default detection duration setting, to reduce channel detection to the business of odd-job channel
The influence of processing.
If receiving detection response message in default detection duration, illustrate the source for sending detection response message
There are neighborhoods between FatAP and the FatAP for sending the probe requests message, and the FatAP of transmission the probe requests message in this way can
To negotiate to establish Mesh link on current sounding channel with these sources FatAP, negotiate the process such as Fig. 3 for establishing Mesh link
Shown (Probe Request message being sent with FatAP1, FatAP2 is received for Probe Request message), it is main to wrap
Include following steps:
The first step, FatAP1 report Mesh Profile (Mesh configuration) Information encapsulation of itself to Probe Request
Wen Zhong sends Probe Request message, on current sounding channel to find neighbours FatAP.
Second step after FatAP2 receives Probe Request message, checks the Mesh that Probe Request message carries
Profile information whether with local Mesh Profile information matches.
Third step, if Mesh Profile information and local Mesh Profile information matches, and Probe
Accepting Peer Links (receiving opposite end connection) set of Request message, then FatAP2 establishes the neighbour with FatAP1
Relationship is occupied, and the Mesh Profile Information encapsulation of FatAP2 itself is sent out into Probe Response (probe response) message
Give FatAP1.
4th step after FatAP1 receives Probe Response message, checks what Probe Response message carried
Mesh Profile information whether with local Mesh Profile information matches.
5th step, if Mesh Profile information and local Mesh Profile information matches, and Probe
The Accepting Peer Links set of Response message, then FatAP1 establishes the neighborhood with FatAP2.
After 6th step, FatAP1 and FatAP2 establish neighborhood mutually, Link Open (link can be sent to opposite end
Open) message, and using the Link Open message of Link Confirm (link acknowledgement) message response opposite end, it is all sent out in the two
After having sent Link Open message and all having received Link Confirm message, Mesh link between the two is successfully established.
After being successfully established Mesh link, FatAP1 can go off the air the probe requests message, utilize current sounding channel
It is carried out wireless communication with FatAP2.
Optionally, following steps can also be performed in Mesh link establishing method provided by the embodiment of the present invention:
If detection response message is not received in default detection duration, alternatively, stopping if Mesh link establishment fails
Broadcast probe request message works on odd-job channel；
When default detection cycle reaches, using next unexplored channel in available channel as current detection letter
Road, and after being switched to current sounding channel from odd-job channel, execute the broadcast probe request message on current sounding channel
The step of, until being successfully established Mesh link, wherein default detection cycle is greater than default detection duration.
If detection response message is not received in default detection duration, alternatively, saying if Mesh link establishment fails
Bright this detection neighbours FatAP failure can not establish Mesh link, need the probe requests message of going off the air, and continuation is being faced
When working channel on work.If current sounding channel and odd-job channel are same channels, without switching channel；
If current sounding channel and odd-job channel are different channel, need to switch back into odd-job from current sounding channel
Channel works on.
In embodiments of the present invention, unexplored channel can be selected from available channel in such a way that poll scans
As current sounding channel, i.e., default detection cycle reach when, using unexplored channel next in available channel as
Odd-job channel is switched to current sounding channel by current sounding channel, the broadcast probe request report on current sounding channel
Text, until being successfully established Mesh link；If detection response message is not received in default detection duration, alternatively, if Mesh
Link establishment failure, then can switch back into odd-job channel and work on, and when next default detection cycle reaches, selection is again
Next unexplored channel is detected as current sounding channel.A length of FatAP broadcast issues detection when default detection
The maximum time interval that detection response message is received after request message is needed since FatAP is when selecting next sounding channel
The time for receiving detection response message is reserved, therefore, default detection cycle can be set greater than to default detection duration.
Optionally, default detection cycle is the multiple of default detection duration, which is greater than or equal to 1 and is less than or waits
In 2.
Since FatAP each in Mesh network may be in the state of channel detection simultaneously, in order to avoid FatAP is visited in broadcast
When surveying request message, other FatAP are also in sounding channel, without the current sounding channel the case where, default detection cycle is not answered
More than 2 times of default detection duration, specifically, default detection cycle TsWith default detection duration TtBetween relationship can be with are as follows: Ts
=(1+ β) Tt, wherein β is the random number that FatAP itself is generated, and range is 0 to 1, can avoid FatAP by random number β and is working as
When scanning is to opposite end FatAP on preceding sounding channel, opposite end FatAP is scanning other channels without in current sounding channel just
Situation occurs.
It further, in embodiments of the present invention, can be on current sounding channel after broadcast probe request message
Execute following steps:
If receiving the probe requests message that other fat AP are sent, in the current detection letter for receiving the probe requests message
Detection response message is sent to other fat AP on road, and suspends broadcast probe request message；
If receiving the link that other fat AP are sent in preset pause duration opens message, established with other fat AP
Mesh link, and after being successfully established Mesh link, it is carried out wireless communication using current sounding channel and other fat AP；If pre-
If not receiving the link that the fat AP in other sources is sent in pause duration opens message, then continue to broadcast on current sounding channel
The probe requests message.
In above process, current sounding channel can be first sounding channel, may not be.It is carried out in FatAP
During detection, which is possible to will receive the probe requests message from other FatAP, in order to avoid simultaneously with one another
Channel switching is carried out, which can suspend broadcast probe request after the probe requests message for receiving other FatAP transmission
Message, time out are set to default pause duration (such as 3s), to improve the success rate for establishing Mesh link.If in default pause
The link for not receiving other FatAP transmission in duration opens message, then explanation can not establish Mesh link, will continue to current
Broadcast probe request message on sounding channel.If the link for having received other FatAP transmission in default pause duration is beaten
Message is opened, then explanation can establish Mesh link each other, after being successfully established Mesh link, can use current detection letter
Road is carried out wireless communication with other FatAP.
