Based on same inventive concept, position, the covering radius of the AP of the WIFI network providing according to the above embodiment of the present invention are determined system, and correspondingly, the embodiment of the present invention also provides the position of a kind of AP of WIFI network, covering radius to determine method, as shown in Figure 2, comprising:
The AP that step S201, WIFI network node reception AP send identifies and the corresponding affiliated WIFI network of network mark of AP, and AP corresponding to AP that determines non-WIFI network in the AP receiving identifies identifies; And identify corresponding AP transmission Location measurement request to this AP determining, and receive this corresponding A P positional information that the request of measuring is returned according to this Location; And send to upper system server the positional information that WIFI network of network mark and corresponding A P are returned under the AP mark determined, corresponding A P.
The AP mark that step S202, upper system server corresponding record receive, affiliated WIFI network of network mark and positional information.
Below in conjunction with accompanying drawing, describe method provided by the invention with specific embodiment, and in the said system therein embodiment of the present invention being provided, WIFI network node and the function of upper system server and the step of execution are described in detail.
Figure 3 shows that in the location determining method of AP of the WIFI network that the embodiment of the present invention provides, the steps flow chart that WIFI network node is carried out, comprising:
Step S301, WIFI network node adopt the determining of position of setting strategy and determine whether to initiate to measure the AP to carry out non-WIFI network, if, entering step S302 starts to measure, otherwise, temporarily do not initiate to measure, specifically can adopt various ways, for example, be set measuring period, in the time that arrive in measuring period, determine and initiate; Also can determine according to the currency of some parameter indexs relevant to self, specific as follows:
In this step, the parameter index of foundation can be in important level, traffic carrying capacity, customer complaint amount and the QoS index of the online quantity of user, location of this WIFI network node one or any number of, and corresponding each parameter index is set metrics-thresholds, and according to each parameter index the relation with corresponding setting metrics-thresholds, determine whether to initiate to measure, for example, when a setting quantity parameter index in multiple parameter indexs all exceedes corresponding setting metrics-thresholds, determine and initiate to measure; Or when a certain parameter index exceedes corresponding setting threshold, determine and periodically initiate to measure; For example: in the time that the online quantity of busy user exceedes 200, determine and periodically initiate to measure; When busy number of users exceedes 150, and location is important service area, and the complaint amount of user average every day is when more than 20 times, determines and initiates single measurement flow process; When the traffic carrying capacity of every day is greater than 2000MByte, and packet loss in QoS index is while being greater than 15%, determines and initiates single measurement flow process.
In step S302, this step, find that the AP of non-WIFI network can adopt following two kinds of modes:
First kind of way: WIFI network node can obtain BSSID and the ESSID of the AP that sends this pilot information from the pilot information receiving, wherein, can determine according to the BSSID obtaining whether this AP is the AP of this WIFI network, can determine according to the ESSID obtaining which WIFI network this AP belongs to, and then can determine whether this AP is the AP of non-WIFI network.
The second way: WIFI network node can also send Beacon and measure request, and receive the beacon message that AP returns, and obtain BSSID and the ESSID of this AP from the beacon message receiving, in like manner, determine according to the BSSID obtaining and ESSID whether this AP is the AP of non-WIFI network.
In this step, if this WIFI network node is newly-built AP, lack basic understanding for the environment of periphery, can find by initiating the second way AP of non-WIFI network; If this WIFI network node is not newly-built AP, but find that online user's quantity obviously declines, also can find by initiating the second way AP of non-WIFI network; In addition, can find the AP of non-WIFI network of part by first kind of way, but may not be all, thus can be according to actual needs, consider to omit the second way.
When the AP that only adopts non-WIFI network of first kind of way discovery can be synchronizeed and carry out with above-mentioned steps S301, and directly enter subsequent step S303 by above-mentioned steps S301.
Step S303, WIFI network node send Location to the AP of newfound non-WIFI network and measure request and Noise Histogram measurement request, specifically can selectively initiate, for example:
Initiate successively Location and measure request and Noise Histogram measurement request; Also can not be newly-built AP at WIFI network node, the network change of location be more stable, only initiates NoiseHistogram and measures request.
The Noise information of returning is asked in positional information and corresponding Noise Histogram measurement that the corresponding Location request of measuring of step S304, newfound this AP of WIFI network node reception is returned.
Positional information and Noise information that this AP that step S305, the processing of WIFI network node receive returns, be only specifically as follows the positional information of reception and Noise information directly sent to upper system server;
Also can, for the Noise information receiving, obtain information wherein, and determine coverage and the covering radius of this AP according to the information of obtaining, and the coverage of this AP determining and covering radius are sent to upper system server, specific as follows:
The Noise information that WIFI network node returns from this AP, obtain the transmitted power of this AP, and according to the signal propagation model of this transmitted power and one's respective area, determine the covering radius of this AP, then in conjunction with the antenna type of this AP, determine the coverage of this AP;
Wherein, the signal propagation model of one's respective area can be according to the signal to noise ratio of the received signal to noise ratio indicating device RSNI instruction of this WIFI network node, estimate the signal propagation model of one's respective area, for corresponding signal propagation model, adopt corresponding algorithm to determine covering radius, taking free space model as example, adopt following formula to determine covering radius:
RL=38.11+20*log10 (R); Wherein, RL is path loss; R is the covering radius of this AP; This formula is to determine according to free space model;
RP=SP-RL+Ag; Wherein, RP is received power; SP is the transmitted power of this AP; Ag is the antenna gain of this AP;
The received power of supposing WIFI network node could normally receive signal when being greater than set point, for example, be greater than 3dBm, establishing RP is this set point 3dBm, the value of Ag can be estimated according to WIFI network standard, SP obtains from the Noise information receiving, and brings above-mentioned formula into, can determine the covering radius of this AP;
Further, according to the antenna type of this AP, for example, be omnidirectional antenna or directional antenna, determine the coverage of this AP.
In this step S305, WIFI network node can also pass through the RCPI receive channel power indicator of self, obtain the received power of the information that receives this AP transmission, and the transmitted power of obtaining is sent to upper system server, relevant information is processed according to this received power by upper system server, referred to the description of the follow-up steps flow chart of carrying out about upper system server side.
This step WIFI network node sends relevant information to upper system server, can be by WIFI network node active reporting, also can, for initiatively being obtained from WIFI network node by upper system server, in the embodiment of the present invention, this not limited.
Flow process shown in above-mentioned Fig. 3 is the position that WIFI network node is determined the AP of non-WIFI network, a kind of scheme of covering radius and coverage, but for a WIFI network node, there is the AP of non-WIFI network in possible its periphery, but due to signal strength signal intensity, the reasons such as self strategy of landform and other non-WIFI network, the measurement request that it sends is (as Location measures request, Noise Histogram measures request, Beacon measures request) can not be received by the AP of non-WIFI network of its periphery, and then also just cannot return to accordingly response message, to this, in the embodiment of the present invention, provide again by flow process shown in Fig. 4 in the location determining method of a kind of AP at WIFI network, the steps flow chart that WIFI network node is carried out, address this problem, comprise:
Step S401, this step can be identical with above-mentioned steps S301.
Step S402, WIFI network node are by the WIFI network associate under known AP and this known AP of non-WIFI network.
After step S403, association, this WIFI network node sends Neighbor Report to this known AP and measures request.
Step S404, this WIFI network node receives the AP list that the corresponding Neighbor Report request of measuring of this known AP is returned.
Step S405, according to existing WIFI technical standard, in this AP list of returning, carry the information of multiple AP of this known AP periphery, for example, for the each AP carrying, comprise the BSSID of AP, ESSID, positional information, use channel information, transmitted power etc., wherein, the BSSID of AP, ESSID, positional information and use channel information are generally more accurate, the accuracy of transmitted power is relatively lower, so, in the embodiment of the present invention, WIFI network node can obtain BSSID and the ESSID of the AP carrying from the AP list receiving, and determine the AP of non-WIFI network according to the BSSID obtaining and ESSID, and obtain the positional information corresponding with the AP of non-WIFI network from this AP list, preferably, can also obtain corresponding use channel information, and send the BSSID of the AP of non-WIFI network in this AP list to upper system server, ESSID, positional information and use channel information, also can only the AP list of reception be sent to upper system server, be processed again by upper system server, refer to the description of the follow-up steps flow chart of carrying out about upper system server side.
Although the transmitted power accuracy of the AP carrying in this AP list is relatively low, but comprehensive for what ensure to measure, also can be according to the transmitted power of the AP carrying in this AP list, adopt the same procedure shown in above-mentioned Fig. 3 to determine covering radius and the coverage of the AP carrying, and send to upper system server, or the transmitted power of the AP carrying is sent to upper system server, and covering radius and the coverage of the AP that this AP list of determining is carried, or whether transmitted power is as final valid data, can be made a decision again by upper system server, refer to the description of the follow-up steps flow chart of carrying out about upper system server side.
In this step S405, WIFI network node can also pass through the RCPI receive channel power indicator of self, obtain the received power of the information that receives this AP transmission, and the transmitted power of obtaining is sent to upper system server, relevant information is processed according to this received power by upper system server, referred to the description of the follow-up steps flow chart of carrying out about upper system server side.
