Embodiment one

Please refer to Fig. 1, the embodiment of the present application provides a kind of wireless network detection method, and described method comprises:

S101: server receives the first measurement parameter that AP scans wireless terminal acquisition, and the second measurement parameter that the described AP scanning adjacent AP adjacent with described AP obtains;

S102: described server is according to N number of described first measurement parameter received in the first preset time period and/or M described second measurement parameter, determine and export wireless network covering quality corresponding to described AP, interference type or fault business, wherein said N, M be greater than 1 integer.

In specific implementation process, server is the wireless Optimization Platform of WLAN, comprises acquisition module, processing module.Wherein, server receives the first measurement parameter of wireless access node (AP:Access Point) scanning acquisition and the second measurement parameter of AP scanning neighbor AP acquisition when performing S101 by acquisition module.Concrete, AP is with form record first measurement parameter of log parameters and the second measurement parameter, and the interface A then specified according to HTML (Hypertext Markup Language) by access controller (AC:Access Controller) sends to server.The incompatible situation of interface A may be there is in the AC due to different vendor, therefore when acquisition module receives the first measurement parameter and the second measurement parameter, can decode to the first measurement parameter and the second measurement parameter further and uniform format conversion, to obtain the first measurement parameter and second measurement parameter of uniform format.

First measurement parameter and the second measurement parameter are wireless measurement parameter (WMP:Wireless MeasureParameter), and multiple first measurement parameter received and the second measurement parameter are used for analyzing the wireless network ruuning situation of AP by the embodiment of the present application.Therefore, S102 is performed: the processing module of server is according to N number of first measurement parameter received in the first preset time period and/or M the second measurement parameter after S101, determine and export wireless network covering quality corresponding to AP, interference type or fault business, wherein N, M be greater than 1 integer.

Wherein, first measurement parameter is after AP associates with each wireless terminal, AP eats dishes without rice or wine to scan the wireless measurement parameter that wireless terminal obtains, and comprising: the MAC Address of wireless terminal, received signal strength (RSSI:Received Signal Strength Indication) i.e. the first received signal strength, signal to noise ratio, channel frequency, type of service i.e. the first type of service, and negotiated speed i.e. the first negotiated speed, correlation time, the authenticated time etc. of wireless terminal.Same, AP also can obtain the second measurement parameter by the adjacent AP that is adjacent of periodic scanning, and the second measurement parameter specifically comprises the MAC Address of adjacent AP, the second received signal strength, signal to noise ratio, frequency channel isolation i.e. the second frequency Signal segregation degree, sweep time etc. with AP.

Please refer to Fig. 2, processing module specifically comprises following seven submodules: data prediction submodule, database, device type be equipped with submodule, statistics submodule, judge submodule, optimize submodule, optimization represent submodule.For the ease of processing module, statistical analysis is carried out to N number of first measurement parameter and/or M the second measurement parameter, before statistical analysis, the first measurement parameter received acquisition module by data prediction submodule and the second measurement parameter carry out structuring parsing, formation take the MAC Address of AC, WLAN hot spot and AP as the in chronological sequence tactic wireless measurement parameter list of three latitudes, and is write in database by the C interface that data prediction submodule communicates with database.Device type is equipped with submodule then for providing the equipment configuration parameter of AP under different manufacturers, different working modes.As AP has indoor conjunction road type, indoor 100mW self, outdoor common 500mW type, base station type AP etc., coverage, the protocol type of dissimilar AP are different, the prioritization scheme produced is also different, and device type matched sub-block is by writing corresponding optimization data in database with the D interface between database for this reason.

Submodule is added up for carrying out statistical analysis to the first measurement parameter received and the second measurement parameter in processing module; Judge that submodule is used for judging whether the data of adding up the acquisition of submodule statistics meet preset rules according to preset rules; Optimize submodule to be used for according to judging that submodule judges that the judged result obtained is determined and exports positioning problems.Concrete, server can determine following problem according to multiple first measurement parameter and multiple second measurement parameter: one, covering problem; Two, interference problem; Three, potential faults problem.

One, covering problem

(1), described server is according to N number of first measurement parameter received in the first preset time period and/or M the second measurement parameter, determine and export wireless network covering quality corresponding to AP, interference type or fault business, specifically can: first being added up to obtain in N number of first received signal strength corresponding to N number of first measurement parameter by statistics submodule has J the first received signal strength to be less than first threshold, and determining that J accounts for first ratio of N, J is positive integer; Then by judging that submodule judges whether the first ratio is greater than Second Threshold, the first judged result is obtained; Judge that the first judged result of submodule shows that the first ratio is greater than Second Threshold when optimization submodule receives, optimize submodule and determine and export wireless network covering quality corresponding to AP to be the weak covering of wireless network, otherwise optimization submodule then needs statistics submodule to do further statistical analysis to determine the ruuning situation of AP.

Such as: suppose that the first predetermined period is that continuous two time-of-weeks are interior, first threshold is-75dBm, Second Threshold is 80%, so add up the number J being less than first received signal strength of-75dBm in N number of first received signal strength in continuous two time-of-weeks of submodule statistics acquisition, and determine that J accounts for first ratio of N, if N=140, J=120, determines that the first ratio is about 85.71%; Judge that submodule judges that the first ratio is greater than Second Threshold, now optimize submodule according to the judged result receiving the first ratio and be greater than Second Threshold, determining and exporting wireless network covering quality corresponding to AP is the weak covering of wireless network.

(2), described server is according to N number of first measurement parameter received in the first preset time period and/or M the second measurement parameter, determine and export wireless network covering quality corresponding to AP, interference type or fault business, concrete also can: first being added up to obtain in N number of first received signal strength corresponding to N number of first measurement parameter by statistics submodule has i the first received signal strength to be greater than the 3rd threshold value, and determining that i accounts for second ratio of N, i is positive integer; Then by judging that submodule judges whether the second ratio is greater than the 4th threshold value, obtains the second judged result; Then determine according to the second judged result the ruuning situation that AP is current by optimization submodule, if the second judged result shows that described second ratio is greater than the 4th threshold value, optimize submodule and determine and export wireless network covering quality corresponding to AP to be that wireless network crosses covering; Otherwise the second judged result shows that the second ratio is less than or equal to the 4th threshold value, optimize submodule and determine that AP does not exist the problem that wireless network crosses covering, need statistics submodule to do further statistical analysis.

Such as: suppose that the cycle very first time is in continuous two weeks, 3rd threshold value is-30dBm, 4th threshold value is 80%, so add up submodule and then can add up the quantity i being greater than first received signal strength of-30dBm in continuous two weeks in N number of first received signal strength, and determine that i accounts for second ratio of N, if N=140, i=70, second ratio of determining is 50%, next, judge that submodule just can judge whether the second ratio is greater than the 4th threshold value, because 50% is less than 80%, therefore obtain the second judged result and show that the second ratio is not more than the 4th threshold value, now optimize submodule and determine that AP does not exist the problem that wireless network crosses covering, statistics submodule is needed to do further statistical analysis to determine whether AP exists other problems.

(3), described server is according to N number of first measurement parameter received in the first preset time period and/or M the second measurement parameter, determine and export wireless network covering quality corresponding to AP, interference type or fault business, specifically all right: first being added up to obtain in N number of first received signal strength corresponding to N number of first measurement parameter by statistics submodule has k the first received signal strength to be less than the second corresponding received signal strength, and determine that k accounts for the 3rd ratio of N, wherein, described AP scans acquisition first received signal strength and obtains the sweep time of the second corresponding received signal strength in same scan cycle with scanning, k is positive integer, then by judging that submodule judges whether the 3rd ratio is greater than the 5th threshold value, the 3rd judged result is obtained, next, optimize submodule determines AP ruuning situation according to the 3rd judged result: if the 3rd judged result shows that the 3rd ratio is greater than the 5th threshold value, optimize submodule and determine and export wireless network covering quality corresponding to AP to be the weak covering of wireless network, if the 3rd judged result shows that the 3rd ratio is less than or equal to the 5th threshold value, optimize the ruuning situation that submodule temporarily cannot determine AP, instruction statistics submodule does further statistical analysis.

Such as: suppose that the first preset time period is in continuous one week, 5th threshold value is 60%, statistics submodule statistics obtains the number k of the first received signal strength being less than the second corresponding received signal strength in N number of first received signal strength, determine that k accounts for the 3rd ratio of N, namely the received signal strength of statistics acquisition AP reception wireless terminal signals is less than the probability that AP in same scan cycle receives the situation generation of the received signal strength of adjacent AP, if N=100, k=65, statistics submodule determines that the 3rd ratio is 65%, again by judging that submodule judges that the 3rd ratio 65% is greater than the 5th threshold value 60%, obtain the 3rd judged result and show that the 3rd ratio is greater than the 5th threshold value, so optimize submodule and then determine and export wireless network covering quality corresponding to AP to be the weak covering of wireless network with the judged result of the 5th threshold value according to the 3rd ratio, determine simultaneously and export the adjacent AP adjacent with AP to there is the problem that wireless network crosses covering.

Two, interference problem

(1), the interference problem of wireless network mainly comprises co-channel interference and alien frequencies interference, for the detection of problem of co-channel interference, can be added up to obtain in N number of first received signal strength corresponding to N number of first measurement parameter by statistics submodule has t the first received signal strength to be greater than first threshold, and determine that t accounts for the 4th ratio of N, t is positive integer, wherein, individual first negotiated speed of the t that individual first received signal strength of t is corresponding is all lower than the 6th threshold value, and t the agreement protocol type that individual first received signal strength of t is corresponding is not all preset kind; Then by judging that submodule judges whether the 4th ratio is greater than the 7th threshold value, the 4th judged result is obtained; Then the ruuning situation of AP is determined according to the 4th judged result by optimization submodule: if the 4th judged result shows that the 4th ratio is greater than the 7th threshold value, determining and exporting interference type corresponding to AP is co-channel interference; Otherwise the further statistical analysis of instruction statistics submodule.Concrete, 6th threshold value can be set to 11M, preset kind can be set to 80% for 11b type, the 7th threshold value, first threshold can be set to-75dBm, and wherein the 7th threshold value and first threshold can be adjusted according to the actual conditions of AP accordingly by designer.

Such as: in continuous two time-of-weeks, under AP, first received signal strength of online wireless terminal of 80% is all greater than-75dBm, but wireless terminal negotiated speed is lower than 11M, and the non-11b type of agreement protocol, then can determine that the wireless network of this AP may exist problem of co-channel interference.Therefore add up submodule statistics and to obtain in continuous two time-of-weeks in N number of first received signal strength corresponding first negotiated speed lower than 11M and agreement protocol type is not 11b type, and received signal strength is less than the quantity t of first received signal strength of-75dBm, determine that t accounts for the 4th ratio and the t/N of N; Then by judging that submodule judges whether t/N is greater than 80% acquisition the 4th judged result, if the 4th judged result shows that t/N is greater than 80%, optimize submodule and then determine and export interference type corresponding to AP to be co-channel interference, otherwise then temporarily cannot determine the interference problem that AP is current, need the further statistical analysis of statistics submodule.

(2), for the detection of problem of co-channel interference, can also be added up by statistics submodule and obtain corresponding N number of first being associated in power and having r first to be associated to power to be less than the 8th threshold value of N number of first measurement parameter, and r first is associated to r corresponding to power the first received signal strength is all greater than first threshold, determine that r accounts for the 5th ratio of N, r is positive integer; Then by judging that submodule judges whether the 5th ratio is greater than the 9th threshold value, the 5th judged result is obtained; Then by judging that submodule determines the ruuning situation of AP according to the 5th judged result: if the 5th judged result shows that the 5th ratio is greater than the 9th threshold value, determining and exporting interference type corresponding to AP is co-channel interference; Otherwise then temporarily cannot determine the interference problem that AP is current, need the further statistical analysis of statistics submodule.

Such as: statistics submodule statistics obtains in continuous two time-of-weeks, N number of first measurement parameter corresponding N number of first be associated to power medium and small in first quantity that is associated to power of the 8th threshold value as 80% be r, and this r the first the first received signal strength being associated to power corresponding is greater than first threshold as-75dBM, determine that r accounts for the 5th ratio of N, suppose to determine that the 5th ratio is 70%, 9th threshold value is 60%, so judge that submodule then judges that acquisition the 5th judged result is that the 5th ratio is greater than the 9th threshold value, under showing AP, more than 60% wireless terminal existence is associated to power lower than 80%, but received signal strength is greater than-75dBM, therefore optimize submodule then to determine and the interference type exporting this AP is co-channel interference.

(3), for the detection of alien frequencies interference problem, can add up by statistics submodule M the second frequency channel isolation obtaining M the second measurement parameter corresponding and all be less than the tenth threshold value; Then by judging that submodule judges whether N number of first received signal strength that N number of first measurement parameter is corresponding is all greater than first threshold, the 6th judged result is obtained; The ruuning situation of AP is determined again according to the 6th judged result: if the 6th judged result shows that N number of first received signal strength is all greater than first threshold by optimization submodule, determining and exporting interference type corresponding to AP is alien frequencies interference, otherwise temporarily cannot determine the interference problem of AP, need statistics submodule to carry out further statistical analysis.

Such as: statistics submodule statistics obtains in continuous two time-of-weeks, M the second frequency channel isolation that M the second measurement parameter that AP scanning neighbor AP obtains is corresponding is all less than 3; Again by judging that submodule judges in this cycle, whether N number of first received signal strength of AP is all greater than first threshold-75dBm, if judge, N number of first received signal strength is all greater than-75dBm, there is the first received signal strength under so showing same AP and be all greater than-75dBm, but the frequency channel isolation of frequency channel is less than 3, so optimizes submodule and determine and export AP to there is the interference problem that interference type is alien frequencies interference.

Three, potential faults problem

(1), AP operationally may run into the inadequate wireless terminal of address pool and frequently to go offline or business configuration shortage of data and terminal such as cannot to be successfully associated at the problem.For the problem that address pool is inadequate, server can be confirmed whether to there is this problem by following steps: first add up by statistics submodule the record that goes offline for p time obtained in N number of first measurement parameter, and p writing time of the record correspondence that goes offline for this p time concentrates in the time period, determine that p accounts for the 7th ratio of N, p is positive integer; Then, by judging that submodule judges whether the 7th ratio is greater than the 11 threshold value, obtain the 7th judged result; Then, the potential faults problem of AP is determined according to the 7th judged result: if when the 7th judged result shows that the 7th ratio is greater than 11 threshold value by optimization submodule, determine and the fault business exporting AP to be address pool inadequate, otherwise confirm concrete potential faults problem again after then doing further statistical analysis by statistics submodule.

Such as: suppose that the first preset time period is in continuous week age, 11 threshold value is 60%, so add up in the continuous week age of submodule statistics acquisition and have 69 records that go offline in 100 the first measurement parameters, the time that namely goes offline writing time that record is corresponding and this goes offline for 69 times all concentrates on and causes ten two points at ten one at noon, so determine that the 7th ratio is 69%, judge that submodule judges that 69% is greater than the 7th judged result that 60% acquisition the 7th ratio is greater than the 11 threshold value, show in continuous week age, under same AP there is frequent lost line in more than 60% wireless terminal, and fault time possesses centrality, optimize submodule thus to confirm and the fault business exporting AP is that address pool is inadequate.

(2) the detection, for AP business datum lacked, specifically first can add up acquisition AP by statistics submodule cannot be successfully associated with arbitrary wireless terminal; And by judging that submodule judges in N number of first measurement parameter, whether N number of first received signal strength is all greater than first threshold, obtain the 8th judged result; If the 8th judged result shows that N number of first received signal strength is all greater than first threshold, optimize submodule and to determine and the fault business exporting AP is business configuration shortage of data, otherwise then need to do further statistical analysis by statistics submodule.

Such as: suppose that the first preset time period is that continuous week age is interior, first threshold is-75dBM, cannot be successfully associated with arbitrary wireless terminal if statistics submodule statistics obtains AP in continuous week age; All normal by judging that submodule judges whether N number of first received signal strength is all greater than-75dBM(further); If judge, N number of first received signal strength is all greater than-75dBM, show in continuous week age, under same AP, all terminals cannot be successfully associated, but received signal strength is all normal, now optimize submodule and to confirm and the fault business exporting AP is business configuration shortage of data.

(3) the detection, for AP business datum lacked, specifically first can also be added up by statistics submodule in N number of first type of service in N number of first measurement parameter of acquisition and there is not the second type of service; Then determine and the fault business exporting AP the second business configuration shortage of data that to be the second type of service corresponding by optimizing submodule.Such as: continuously in week age, under same AP, all wireless terminals cannot be successfully associated for service set (the SSID:Service Set Identifier) business of second service type, but other SSID business are normal, now optimize submodule and determine and export the second type of service configuration data disappearance corresponding to this AP.

Can change according to the effect before and after the actual conditions of different AP and optimization the decision rule of AP ruuning situation above, the application does not limit the concrete decision rule differentiating AP ruuning situation.

In specific implementation process, server is according to N number of first measurement parameter received in the first preset time period and/or M described second measurement parameter, determine and while exporting wireless network covering quality corresponding to AP, interference type or fault business or afterwards, server also represents covering quality, interference type or the fault business correspondence that submodule correspondence determines and exports by optimizing the first optimisation strategy optimizing AP.Concrete, for weak covering problem, export the first optimisation strategy: verify and adjustment AP transmitting power; If transmitting power has reached AP maximum power, then export the first optimisation strategy: suggestion adjustment AP coverage is (as AP installation site uses region, adjustment AP antenna direction near wireless terminal, increases room divided antenna etc.; For crossing covering problem, the first optimisation strategy can be exported: the transmitting power of adjustment AP or adjustment AP antenna direction etc.For potential faults problem, the first optimisation strategy can be exported: verify configuration data by WLAN webmaster whether abnormal or by AP initialization business configuration data etc.

After the covering quality of server corresponding A P, interference type or fault business export the first optimisation strategy optimizing AP, the wireless network detection method that the embodiment of the present application provides also comprises: in the second time cycle after the first preset time period, M the 4th measurement parameter that described in N number of 3rd measurement parameter that server obtains in conjunction with AP surface sweeping wireless terminal in the first optimisation strategy and the second preset time period and/or AP surface sweeping, adjacent AP obtains, determines and exports second optimisation strategy of AP.Concrete, server according to the effect before and after the optimization of the wireless measurement parameter characterization before and after front and back optimisation strategy and optimization, further can optimize AP.

Below in conjunction with specific embodiment, the wireless network detection method that the embodiment of the present application provides is described in detail.Suppose that the WLAN of 3 layers of office building covers, basic condition is: Fig. 3 is individual layer Administrative Area, installs 1 AP and covers.Every floor Administrative Area is identical.1st floor AP names AP1, and 2nd floors AP names AP2, and 3rd floors AP names AP3.

First stage is optimized, and AP radio network problems location and the first optimisation strategy export:

Server receives AP2 and scans the wireless terminal associated with it and the first measurement parameter obtained, count wireless terminal that AP2 associates with it in continuous two weeks, to be less than the occurrence frequency of first threshold as first received signal strength of-75dBm to reach more than 80%, statistics submodule utilizes this WLAN hot spot AP inventory of E interface quick position.Optimization submodule exports this WLAN hot spot according to decision rule and there is the weak covering problem of AP2, and its zone location is this wireless terminal position (little Administrative Area).

Optimization submodule goes out this hot spot coverage according to identical focus numbering quick position and there are three AP.Checked by contiguous AP WMP, AP2 and AP1, AP3 can form mutual interference, but AP1 and AP3 can not form interference.AP2 can be subject to the homogenous frequency signal of other floors AP1 and AP3, but does not reach co-channel interference standard (being less than-90dBm).

According to weak Mulching treatment rule, solve weak covering problem by adjustment AP2 transmitting power mode, the covering quality of contiguous AP should not be affected.Due to adjustment AP2 transmitting power, contiguous AP1 and AP3 co-channel interference can be increased, affect the wireless coverage quality of 1st floor and 3rd floors.Therefore two prioritization schemes are exported:

(1) adjust the frequency of AP1, AP3, make its AP2 that gets along well form co-channel interference, increase the transmitting power of AP2, the coverage of AP2 is synchronously increased to 1st floor and 3rd floors.

(2) not adjusting the transmitting power of AP2, solving by increasing the directed extension antenna of AP.

Consider that on-site working region number may increase further, in fact simple adjustment AP2 power reduce the covering user capacity of AP2, optimizes submodule and export suggestion further: adopt prioritization scheme 2.Webmaster then can directly be optimized according to prioritization scheme 2.

Second stage is optimized, and exports the second optimisation strategy in conjunction with the first optimisation strategy and wireless measurement parameter:

The wireless terminal being obtained AP2 association by statistics submodule is frequently gone offline in the section sometime concentrated, wireless terminal quantity reaches the maximum quantity restriction of AP, solve weak covering problem owing to increasing extension antenna by the first optimisation strategy AP2, but create the inadequate problem of AP2 address pool.

The capacity of adjacent AP is checked by statistics submodule, find that AP3 average associated terminal number is little, optimize submodule and export the second optimisation strategy: suggestion adjustment AP3 transmitting power and frequency point setting, under not forming the prerequisite of co-channel interference with AP2, absorption portion is from the wireless terminal of 2nd floors Administrative Areas.

Phase III is optimized, and exports the 3rd optimisation strategy in conjunction with the second optimisation strategy and wireless measurement parameter:

The wireless terminal number being obtained AP3 association by statistics submodule statistics is increased to some extent, but the wireless terminal quantity of AP2 association reaches the frequency of maximum quantity restriction, and to reach more than 50%, AP2 address pool still inadequate.Through dam site investigation confirm, 2nd floors wherein an office made meeting room into.Session occurs that part WLAN wireless terminal cannot be surfed the Net.Mode by means of only adjustment wireless coverage still cannot solve capacity problem at all, therefore exports the 3rd optimisation strategy: increase an AP for 2nd floors newly and solve the inadequate problem of address pool.

Above-mentioned wireless network detection method can perform by circulation continuous, i.e. at least S101, S102 again after S102, and according to long historical data accumulation and contrast, and the principle of optimality is constantly perfect, can reach the effect more optimized.The setting of the WLAN Optimization Platform functional module of the embodiment of the present application, by following the tracks of WLAN wireless terminal, can gather the wireless measured data of extensive wlan network, optimization problem location, and Usefulness Pair ratio can be carried out to the historical data of database by statistics submodule, server provides the platform that continues the management of wireless Optimizing Flow for this reason.

In above-described embodiment, scan the first measurement parameter of wireless terminal acquisition by receiving AP, and the second measurement parameter that the described AP scanning adjacent AP adjacent with described AP obtains; According to multiple described first measurement parameter received in preset time period and/or multiple described second measurement parameter, determine and export wireless network covering quality corresponding to described AP, interference type or fault business, thus in solution prior art there is the technical problem that accurately cannot reflect wireless network covering quality in the optimum detection of wireless network, realize the detection to wireless network covering quality, improve radio network optimization quality.

Meanwhile, periodically determined by server and export covering quality, interference type or the fault business to wireless network, and in conjunction with the optimisation strategy in last cycle and the measurement parameter in next cycle, export better optimisation strategy for the problems referred to above, reach preferably running status to enable wireless network.Further, due to server to data-handling efficiency far above artificial treatment efficiency, can operation problem be there is in Timeliness coverage or reduction wlan network running and provide suggestions on Optimization, significantly promote WLAN wireless monitor level and Optimization Work efficiency.
