In order to ensure in many AC scene, AC can the radio frequency environment information of AP real-time collecting of other AC of perception management, it is thus possible to control the Radio transmit power of this AP with reference to the signal receiving strength of other AP all covered of AP in scene, to optimize radio frequency resource control effect under many AC scene, in embodiments of the present invention, neighbours' radio-frequency information that mutual themselves capture arrives it is required between many scenario As C.

As the optional embodiment of one, in embodiments of the present invention, in order to achieve the above object, it is possible to the AP of AC and management thereof regards as an EVI website, and AC is as ED (EdgeDevice, edge device), AP, as equipment in private network, sets up EVI neighborhood, and sets up EVI connection between AC, and then, this EVI neighbours' Radio information connecting the AP of mutual collected self-management can be passed through between AC.

Correspondingly, in one embodiment, after above-mentioned AC collects neighbours' Radio information of the AP of self-management, it is also possible to including:

Neighbours' Radio information is sent to neighbours AC by AC, so that neighbours AC controls the Radio transmit power of the AP of self-management according to neighbours' Radio information of the AC the received neighbours' Radio information sent and themselves capture.

As the optional embodiment of one, in embodiments of the present invention, by LSP message transmissions neighbours' Radio information between AC and neighbours AC;Wherein, LSP (LinkStatePacket, Link State Packet) message carries neighbours' Radio information by MAC-Reachability (accessibility) TLV (Type, Length, Value, type lengths values).

Table 2

What deserves to be explained is, in embodiments of the present invention, between above-mentioned steps 201 and step 202 and be absent from inevitable sequential relationship, namely can first carry out step 201, rear perform step 202; Can also first carrying out step 202, rear execution step 201, it implements and does not repeat them here.

Neighbours' Radio information that step 203, AC send according to neighbours' Radio information and the neighbours AC of themselves capture, controls the Radio transmit power of the AP of self-management.

In the embodiment of the present invention, AC collects neighbours' Radio information of the AP of self-management, and after receiving the neighbours AC neighbours' Radio information of AP being connected this neighbours AC management sent by EVI, the neighbours' Radio information that can send according to neighbours' Radio information of this themselves capture and neighbours AC, controls the Radio transmit power of the AP of self-management.

As the optional embodiment of one, in above-mentioned steps 203, neighbours' Radio information that AC sends according to neighbours' Radio information and the neighbours AC of themselves capture, control the transmit power of the Radio of the AP of self-management, it is possible to comprise the following steps:

11), for the Radio mouth of arbitrary AP of AC management, neighbours' Radio information that AC sends according to neighbours' Radio information and the neighbours AC of themselves capture, it is determined that the appointment Raido mouth of the Raido mouth of this AP;

12), AC adjust threshold value according to the predetermined power of the Radio mouth that this appointment Radio mouth detects the signal receiving strength of Radio mouth that the Radio mouth of this AP sends and this AP, adjust the Radio transmit power of the Radio mouth of this AP.

In this embodiment, AC has collected neighbours' Radio information of the AP of self-management, and after receiving neighbours' Radio information of AP of neighbours AC this neighbours AC sent management, it is possible to the appointment Radio mouth of the Radio mouth of this AP is determined according to neighbours' Radio information of neighbours' Radio information of themselves capture and neighbours AC transmission.

Alternatively, above-mentioned steps 11) in, neighbours' Radio information that AC sends according to neighbours' Radio information and the neighbours AC of themselves capture, it is determined that the appointment Radio mouth of the Raido mouth of this AP, it is possible to including:

When neighbours' Radio mouth number of the Raido mouth of this AP reaches minimum neighbours' number that trigger power adjusts, AC detects the signal receiving strength of the Raido of the Radio mouth transmission of this AP according to each neighbours' Radio mouth of the Raido mouth of this AP, and neighbours' Raido mouth strong for signal receiving strength K is defined as the appointment Raido mouth of the Radio mouth of this AP; Wherein, K is for presetting neighbours' factor, and K is positive integer.

Further, in order to select neighbours' Radio mouth strong for K more easily, AC can also detect the signal receiving strength of the Raido of the Radio mouth transmission of this AP by by force to weak order according to each neighbours' Radio mouth of the Raido mouth of this AP, each neighbours' Raido mouth is ranked up, and AC selects neighbours' Radio mouth strong for K to be defined as the appointment Raido mouth of Radio mouth of this AP according to presetting neighbours' factor from the neighbours' Radio mouth after sequence.

Concrete, in this embodiment, Radio mouth for arbitrary AP of AC management, AC can determine neighbours' Radio mouth number of the Raido of this AP according to neighbours' Radio information that neighbours' Radio information of themselves capture and neighbours AC send, and determines if to reach minimum neighbours' number that trigger power adjusts.

Such as, Radio1 for the AP1 in table 2, the minimum neighbours' number assuming trigger power adjustment is 2, then AC1 may determine that according to the whole network NRDB of self maintained neighbours' Radio mouth of the Radio1 of AP1 includes the Radio1 of Radio1 and the AP4 of Radio1, AP3 of AP2, namely the quantity of neighbours Radio mouth is 3, reaches minimum neighbours' number that trigger power adjusts.

When AC determines that neighbours' Radio mouth number of the Radio mouth of AP reaches minimum neighbours' number that trigger power adjusts, AC can detect the signal receiving strength of the Radio of the Radio mouth transmission of this AP according to each neighbours' Radio mouth of the Radio mouth of this AP, and neighbours' Raido mouth strong for signal receiving strength K is defined as the appointment Raido mouth of the Radio mouth of this AP. Wherein, the signal receiving strength K of neighbours Radio mouth shows by force to exist the signal receiving strength of the Radio that K-1 the Radio mouth detecting this AP sends and is better than other neighbours' Radio mouth of this neighbours' Radio mouth.

Such as, still for the Raido1 of above-mentioned AP1, AC1 may determine that the Radio1 of this AP1 that each neighbours' Raido mouth of the Radio1 of AP1 the detects signal receiving strength respectively-50dBm (Radio1 of AP2) of the Radio ,-75dBm (Radio1 of AP3) sent and-55dBm (Radio1 of AP4) according to the whole network NRDB of self maintained, then by by force to weak order ranking results be-50dBm >-55dBm >-75dBm.

Assume that the neighbours' factor preset is 2, then AC can by neighbours' Radio mouth of signal receiving strength the last 2, and namely corresponding for-55dBm Raido mouth (i.e. the Raido1 of AP4) is defined as the appointment Radio mouth of the Radio1 of AP1.

Alternatively, in above-mentioned steps 12) in, the predetermined power of the signal receiving strength of the Raido that AC sends according to the Radio mouth specifying Radio mouth to receive this AP and the Raido mouth of this AP adjusts threshold value, adjusts the Radio transmit power of the Raido mouth of this AP, it is possible to comprise the following steps:

21), AC compares signal receiving strength and the described predetermined power adjustment threshold value of the Raido specifying the Radio mouth that Radio mouth detects this AP to send;

22) if this appointment Radio mouth detects the signal receiving strength of Raido that the Radio mouth of this AP sends and adjusts threshold value more than predetermined power, and difference is more than the first preset value (such as 6), then AC reduces the Raido transmit power of the Raido mouth of this AP;

23) if this appointment Radio mouth detects the signal receiving strength of Raido that the Radio mouth of this AP sends and adjusts threshold value less than predetermined power, and difference is more than the second preset value (such as 3), then AC increases the Raido transmit power of the Raido mouth of this AP.

For example, still for the Raido1 of above-mentioned AP1, assume that predetermined power adjusts threshold value for-65dBm, the signal receiving strength of the Radio detecting the Radio1 transmission of AP1 due to the appointment Radio mouth (i.e. the Raido1 of AP4) of the Radio1 of AP1 is-55dBm, threshold value (-55dBm >-65dBm) is adjusted more than predetermined power, and difference is more than 6, therefore, AC can increase the transmit power of the Radio1 of AP1.

Further, in embodiments of the present invention, when neighbours' Radio information that AC determines the AP of self-management changes, the neighbours' Radio information after change can be sent to neighbours AC by this AC.

Such as, when the signal receiving strength of AP detection to neighbours' Radio mouth changes, AP can report the AC managing this AP, and then, AC can pass through EVI and connect the message sending the neighbours' Radio information after carrying change to neighbours AC, so that neighbours AC updates the whole network NRDB of self maintained according to this message.

Further, in order to avoid mutual neighbours' Radio information frequent between AC, increase cost of device, threshold value can be adjusted according to predetermined power and triggering neighbours' Radio information updating activation threshold value is set, such as 3dBm, namely when AC determines that in neighbours' Radio information of the AP of self-management, signal receiving strength just can trigger neighbours' Radio information updating when varying more than 3dBm, as carried the transmission of the LSP message of the neighbours' Radio information after change.

Visible, in the method flow described by Fig. 2, AC mono-aspect can collect neighbours' Radio information of the AP of self-management, neighbours' Radio information of the AP of the neighbours AC neighbours AC sent management can be received on the other hand, and then, the Radio transmit power of the AP of self-management can be controlled according to neighbours' Radio information that neighbours' Radio information of themselves capture and neighbours AC send, achieve the radio frequency environment information of the AP real-time collecting of other AC of AC perception management, optimize radio frequency resource under many AC scene and control effect.

Radio transmission power control (assuming that AP1 adopts power to adjust thresholding default value-65dBm, configuration neighbours' factor is 2) for AP1.

According to existing WLANRRM scheme, due to only by power adjustment reference could be realized between the same AC AP managed, therefore AP1 detects neighbours' Radio mouth number is 2 (Radio1 of Radio1 and the AP3 of AP2), reaches minimum neighbours' number that trigger power adjusts.Assuming that AP2 detects the signal intensity of AP1 by Radio1 to be-50dBm, AP3 detect the signal intensity of AP1 by Radio1 be-75dBm, AP4 is-55dBm by the Radio1 signal intensity detecting AP1. Due in existing WLANRRM scheme, only adjust reference using the signal receiving strength of the same AC AP managed as power, therefore, AP1 can choose the Radio of AP3 as specifying Radio mouth, through judging that-75dBm adjusts threshold value-65dBm less than power, and difference is more than 3dBm, then AP1 can increase its transmit power.

And the technical scheme provided according to embodiments of the present invention, AC mono-aspect can collect neighbours' Radio information of the AP of self-management, safeguard local NRDB (its form can be as shown in table 1), neighbours' Radio information of the AP (AP4) of neighbours AC (AC2) AC2 sent management can be received on the other hand, and according to local NRDB, and neighbours Radio maintenance of information the whole network NRDB that neighbours AC sends. Assume that the AC1 the whole network NRDB safeguarded is as shown in table 2, then, when AC1 needs the Radio transmit power of AP1 is adjusted, its concrete operation step can be such that

1, with the Radio of AP1 MAC (N) field being key search table 2, it is possible to get the signal receiving strength that all neighbours' Radio mouths of AP1 detect;

2, according to above-mentioned information, signal receiving strength is by being ordered as AP2 > AP4 > AP3 to weak by force;

3, neighbours' factor of AP1 configuration is 2, thus the Radio mouth choosing AP4 is appointment Radio mouth;

4, specify the signal receiving strength of Radio mouth to adjust threshold value with the power of AP1 to compare :-55dBm >-65dBm, and difference is more than 6, therefore AC can adjust, according to certain, the Radio transmit power that step-length tunes up the Radio mouth of AP1.

Visible, in the technical scheme of the embodiment of the present invention, AC is when adjusting the Radio transmit power of AP of self-management, not only allow for the signal receiving strength of the Radio mouth of the AP of same AC management, also contemplate the signal receiving strength of the Radio mouth of the AP of other AC management, achieve the radio frequency environment information of the AP real-time collecting of other AC of AC perception management, with in prior art only using the signal receiving strength of the Radio mouth of the same AC AP managed compared with the realization adjusting reference, optimize under many AC scene radio frequency resource and control effect.

Should be realized that, although this embodiment is all only opened a Radio mouth and is illustrated with each AP, but being not limited to each AP in the technical scheme that the embodiment of the present invention provides and only open a Radio mouth, namely each AP can also open two or more Radio mouth. Wherein, when certain AP opens and has multiple Radio mouth, the plurality of Radio mouth can also be mutually neighbours Radio, and radio frequency resource control realization in this case is similar with the related realization in above-described embodiment, and the embodiment of the present invention does not repeat them here.
