Embodiment

For making the purpose, technical solutions and advantages of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.

Fig. 1 is the flow chart of the method for testing embodiment one of WLAN (wireless local area network) of the present invention, and as shown in Figure 1, present embodiment specifically comprises the steps:

Step 100, the test WAP (wireless access point) of wireless terminal scanning neighboring, and the identification information of each WAP (wireless access point) that will scan sends to the wireless controller of connection;

The method of testing of WLAN (wireless local area network) of the present invention is based on the wireless network topology structure of existing wireless terminal STA, wireless access point AP and wireless controller AC and carry out, need not to change existing WLAN (wireless local area network) topological structure, need not in network topology structure to add on the basis of any extra hardware device, based on the existing to each other situation that communicates to connect of each wireless device in the existing WLAN, realized automatic exploration to the network condition of wireless network.

Particularly, in the present invention, in order targetedly the performance condition of certain location or the WLAN (wireless local area network) that certain is regional to be surveyed, with timely discovery and solve the variety of issue that WLAN may exist or exist in disposing and being provided with, the wireless terminal STA of a test usefulness can be set in location to be surveyed or zone in advance.This test can be the STA terminal arbitrary common, that be provided with wireless network card in this location or the zone with STA.Based on the wireless network card that self is provided with, this test can be when being linked in the WLAN (wireless local area network) for the first time with STA, all contiguous attachable AP are scanned, specifically refer to receive beacon (beacon) frame that all contiguous attachable AP send by wireless network card, the basic identification information that has comprised each AP equipment in this beacon frame, test can be according to each the beacon frame that receives with STA, scans and knows all contiguous attachable AP equipment.

And after scanning each contiguous AP equipment, learn this scanning result in order to make the AC equipment in this location or the zone, so that AC equipment carries out unified management to each AP equipment, among the present invention, the identification information of each AP that test also will scan with STA, refer to that specifically the address identification message of each AP sends to the AC of connection,, thereby can arrive corresponding AP according to the identification information pathfinding of each AP that receives so that AC is known the quantity of its pairing AP and the sign of each AP.

Particularly, test can be decided the mode that scanning result sends to AC according to the connected mode of existing STA and AC with STA, when if STA is connected with AC equipment indirectly by AP, STA will be forwarded to scanning result in the AC equipment by AP indirectly, and if STA is the connected mode by other, when for example directly being connected with AC equipment by cable network, STA can also pass through these other connected mode, directly scanning result is sent to AC equipment.

Step 101 when wireless controller receives the test request that test sends with wireless terminal, sends data to each WAP (wireless access point) corresponding with the identification information that receives and obtains instruction;

After AC equipment receives the identification information of test with each AP of STA transmission, the identification information of each AP of receiving is preserved, these and each identification information one to one each AP just among the present invention, be used for the network equipment that the data of the performance condition of reflection WLAN (wireless local area network) are gathered and added up.Thereby, when AC equipment receives the test request that test sends with STA, can be according to each the AP equipment mark information that receives before, be addressed to each corresponding AP, in order to respond the test request that STA sends, AC equipment obtains instruction to each the AP equipment sending data that is addressed to, and returns with the network performance status data of indicating each AP equipment to gather and to count on simultaneously, so that AC equipment is analyzed current network state according to these network performance status datas.

Particularly, the test request that test sends to AC equipment with STA can automatically periodically be sent to AC equipment, so that AC equipment periodic ground is tested current wireless network state for the default request transmission frequency of this STA terminal basis; Simultaneously, this test request can also for survey crew at the Local or Remote end, control this test and send, and in this case with the STA terminal, when survey crew sent test request for Long-distance Control STA, the present invention had also realized the Long-distance Control exploration to WLAN (wireless local area network).

Next need to prove, in the present invention, adopt AP equipment to be: because in WLAN (wireless local area network) as the reason of the network equipment of collection network performance state data, AP equipment directly is connected with each wireless terminal, and the effect of AP equipment is, be responsible for each wireless terminal is accessed in the Ethernet, and the data service of each wireless terminal is transmitted and handled.Thereby for AP equipment, after its all wireless terminals that can get access to correspondence access to wireless network, with all mutual control message and business datum messages of wireless network, thereby it carries out statistical analysis by control message and the business datum message that self is handled and transmits, and the result that statistical is separated out can reflect the Business Processing situation of each wireless terminal in wireless network exactly.And after all the AP equipment in this location or the zone all carry out same statistical analysis, to reflect the gathering of statistic analysis result the network communication state of the interior WLAN (wireless local area network) in this location or zone further exactly.

Step 102, each WAP (wireless access point) is obtained instruction according to the data that receive separately, returns the network performance status data of gathering separately and counting to wireless controller;

Each AP equipment receives after data that AC issues obtain instruction, learn that AC equipment need obtain the network performance status data relevant with self, thereby obtain instruction in order to respond these data, network performance status data that each AC equipment will be preserved separately, that from the network service running, gather and count on, return to AC equipment, so that AC equipment is known relevant network operation situation according to these network performance status datas.

Particularly, for each AP equipment, its network performance status data of gathering in running and counting should comprise following two types at least:

Primary sources are for can reflect the transmission performance situation of this AP equipment self and the data of state status intuitively, and this class data message can reflect the transmission performance situation of this corresponding AP equipment to the data message intuitively.Particularly, these class data can comprise: the data messages such as quantity, type and speed of self radio frequency mouth of going out of this AP device statistics all data messages of sending out and receiving for example, according to this data message, AC equipment can know intuitively that this AP equipment is in the transmission performance situation of running to the data message; Secondly, these class data can also comprise that the data message of various abnormalities appears in this AP equipment of reflection that the AP device statistics goes out, data messages such as the occurrence frequency that for example resets, cpu busy percentage and Packet Error Rate, and according to these abnormality data messages, AC equipment can obtain this AP equipment intuitively and the frequency of various abnormal conditions and the intensity of abnormal conditions occur in running.

Second class is for reflecting the data of all STA terminals transmission performance state separately that this AP equipment is entrained intuitively.For example: the quantity information of all STA terminals that this AP equipment is entrained, according to this quantity information can know intuitively each AP equipment all separately correspondence managed what STA terminals; Further, these state performance data can also comprise pairing each the STA terminal of AP equipment signal strength signal intensity, flow, connection speed, wrong data messages such as quantity that wrap number and send various rate frame separately, according to these data messages, AC equipment can be known data service flow and the situation such as signaling traffic of the pairing STA terminal of each AP equipment in WLAN (wireless local area network) intuitively, and these condition informations relevant with STA can also be from reflecting the network service quality of WLAN (wireless local area network) on the one hand further.

Need to prove, in this step, the network performance status data that is returned when the data of each AP device responds AC equipment are obtained instruction, can for each AP equipment by in running, in real time various performance parameters being gathered and are added up, and the related data information in a period of time that draws, and this a period of time be generally and received data from last time and obtain to instruct and receive data specifically and obtain blanking time the instruction.Promptly for most of data that AP equipment returns, the quantity of the data message that for example sends and receive for the radio frequency mouth, data such as type and speed, each AP equipment is not to be to receive data that AC equipment issues when obtaining instruction at this, just begin these data messages are added up, on the contrary, in the present invention, each AP equipment carries out in running with statistics in real time to the collection of each performance data, and obtaining when instruction receiving data, AP equipment only is that each the network performance status data that will count in during this period of time feeds back to AC equipment.

Step 103, wireless controller is according to default statistical analysis strategy, and the network performance status data that each WAP (wireless access point) is returned carries out statistical analysis, to know the current running status of WLAN (wireless local area network).

Each AP device responds data is obtained instruction, the data message relevant with own performance condition that to gather and count separately is uploaded to after the AC equipment, be equivalent to the relevant data message of diverse network behavior that fed back in each comfortable wireless network running to participate in relating to AC equipment, these data messages have reflected the network operation situation of each AP equipment and pairing STA terminal well and intuitively, have been equivalent to reflect the ruuning situation of whole WLAN.Thereby receive these network performance status datas at AC equipment, and according to default statistical analysis strategy, after these network performance status datas are carried out statistical analysis, according to The result of statistics, the operation conditions of whole WLAN can be understood and know to AC equipment accurately, is equivalent to the operation conditions of WLAN has been carried out once effectively test.

The method of testing of the WLAN (wireless local area network) of present embodiment, based on existing by STA, the wireless network topology structure that AP equipment and AC equipment are formed and realizing, need not in WLAN (wireless local area network), to increase on the basis of hardware device, by initiating test request with STA to AC equipment by test, AC equipment obtains each AP equipment collection and counts to each AP equipment of correspondence, with each autocorrelative network performance status data, and by the performance state data of AC equipment according to each AP equipment that gets access to, corresponding AP equipment is carried out statistical analysis and test, thereby statistical test result based on AC equipment, AC equipment can be analyzed the current running status that draws WLAN (wireless local area network), compare with present exploration instrument, method of testing of the present invention has not only reduced hardware cost, and this method of testing is possessed based on the AP equipment self, to the collection statistical power of self performance status data and carry out, the performance state data that AP equipment is directly gathered and counted can reflect the performance state and the disposal ability of each AP equipment intuitively, greatly reduce the probability of erroneous judgement.

Fig. 2 is the flow chart of the method for testing embodiment two of WLAN (wireless local area network) of the present invention, and as shown in Figure 2, present embodiment specifically comprises the steps:

Step 200, test scans contiguous AP equipment with STA;

Step 201, whether test has exceeded default signal strength threshold with the signal strength values that STA detects each the AP equipment that scans;

Step 202, the AP equipment mark information that test exceeds default signal strength threshold with STA with signal strength values sends to the AC equipment of connection;

In the present embodiment, test with STA when just accessing in the wireless network, at the beacon frame that sends according to each AP equipment of the vicinity that receives, after scanning each contiguous AP equipment, each AP equipment mark information that directly will not scan sends to the AC of connection, but can at first once filter all AP equipment that scan, to filter out to the exploration of the WLAN (wireless local area network) less AP equipment of influence power as a result, select those to the exploration AP equipment that capability of influence is bigger as a result, and these AP equipment mark information that will select send to the AC equipment of connection.

Particularly, in this step, according to the capability of influence of each AP equipment to the exploration result, the concrete grammar that AP equipment is filtered can be beacon frame that test receives in basis with STA, scan attachable each AP equipment mark information, specifically refer to scan media interviews control (the Media Access Control of each AP equipment, be called for short MAC) address time, test can also test out the signal strength values of each corresponding AP equipment according to the relevant information of carrying in each beacon frame that receives automatically with the receiving circuit of the inner wireless network card that is provided with of STA.The height of this signal strength values has reflected that each corresponding AP equipment is to the size of test with the effect of signals ability of STA.

Particularly, when testing with STA according to a certain beacon frame that receives, test out the signal strength values of the AP equipment that sends this beacon frame when higher, represent this AP equipment bigger with the effect of signals ability of STA to test, possible this AP equipment distance test close together of STA, thereby when test is tested with the performance condition of the WLAN (wireless local area network) of STA region, this AP equipment must also have considerable influence to the communication operation of wireless network in this zone, it need be listed in to a plurality of AP equipment of assisting test usefulness; And on the contrary, if a certain beacon frame that test receives with the STA basis, test out the signal strength values of the AP equipment that sends this beacon frame when low, represent this AP equipment less with the effect of signals ability of STA to test, possible this AP equipment distance test is far away with the distance of STA, thereby when test is tested with the performance condition of the WLAN (wireless local area network) of STA region, because this AP equipment is less to the influence of the communication operation of wireless network in this zone, when need not to consider the associated transport ability of this AP equipment, also can test this regional wireless channel conditions exactly, thereby can need not this AP equipment is listed in to a plurality of AP equipment of assisting test usefulness, and filter out this AP equipment.

Thereby, according to above-mentioned principle, in the present embodiment, can preset a signal strength threshold in test with STA inside, the size of this signal strength threshold can be a critical value that rule of thumb is provided with, and when testing with STA according to each beacon frame that receives, after detecting the signal strength values of each corresponding AP equipment, this test can compare detected each signal strength values and the signal strength threshold of presetting with STA, the AP equipment that has only signal strength values to be higher than this signal strength threshold just can exert an influence to the wireless communication operation conditions of one's respective area, thereby test gets final product with the AC equipment that STA only needs the AP equipment mark information that signal strength values exceed this signal strength threshold to be sent to connection.And when carrying out the test of WLAN (wireless local area network), AC equipment also only can be analyzed the performance state of this regional WLAN (wireless local area network) according to the network performance status data of these AC equipment feedbacks.In the practical application, this signal strength threshold can be set to 65Dbm usually.

Step 203, test sends test request with STA to AC equipment;

Step 204, AC device responds test request is obtained instruction to each AP equipment sending data corresponding with each identification information that receives;

After AC equipment receives the identification information of test with each AP of STA transmission, the identification information of each AP of receiving is preserved, thereby when receiving the test request that test sends with STA, can be according to these identification informations of preserving, be addressed to each corresponding AP equipment, obtaining instruction to these AP equipment sending datas, that these data are obtained is that instruction is used to indicate these AP equipment to return respectively and gathers separately and count, with oneself relevant network performance status data.

Identical with a last embodiment, in the present embodiment, the test request that test sends to AC equipment with STA, can be the default transmission frequency of this STA terminal basis equally, periodically the test request of sending to AC equipment periodically sends test request AC equipment periodic ground is tested current wireless network state; Simultaneously, this test request can also for survey crew at the Local or Remote end, control this test and send, in this case with the STA terminal, when the test of survey crew's Long-distance Control was sent test request with STA, the present invention had also realized the Long-distance Control exploration to WLAN (wireless local area network) of remote port control.

Step 205, each AP equipment obtains instruction according to the data that receive separately, returns the network performance status data of gathering separately and counting to AC equipment;

And the content that specifically comprises about the network performance status data, can be with reference to the associated description among the last embodiment, particularly, for each AP equipment, its network performance status data relevant with self of gathering in running and counting should comprise two types data usually: first kind is the transmission performance data relevant with this AP equipment oneself, these transmission performance data have reflected the transmission performance of this AP equipment self, for example this AP equipment sends and the quantity of total data message of reception, type and speed, the perhaps reset rate of this AP equipment, cpu busy percentage and Packet Error Rate etc.; Second kind of data is and the relevant performance state data of the pairing STA terminal of this AP equipment, these performance state data have reflected total performance state of all STA terminals that this AP equipment is managed, the quantity of signal strength signal intensity, flow, wrong bag number and various rate frame that for example total quantity of the pairing STA terminal of this AP equipment, and pairing all the STA terminals of this AP equipment is total etc.

Step 206, AC equipment is according to default statistical analysis strategy, and the network performance status data that each AP equipment is returned carries out statistical analysis, to know the current running status of WLAN (wireless local area network);

After AC equipment receives the network performance status data relevant with self that each AP equipment returns, for the operation conditions of the WLAN (wireless local area network) for the treatment of test zone is tested, need be according to the statistical analysis strategy that sets in advance, these network performance status datas that get access to are carried out corresponding statistical analysis, thereby according to The result of statistics, the operation conditions of the whole WLAN in the zone to be tested can be understood and know to AC equipment accurately.

Particularly, because each network performance status data that AC equipment gets access to is and the device-dependent network performance status data of single AP, it is the performance state that every piece of data has all only reflected an AP equipment, thereby, for the whole WLAN for the treatment of in the test zone is tested, promptly treat the performance state of all the relevant AP equipment in the test zone and test, AC equipment needs pointedly to be added up the network performance status data of some AP equipment that are associated.For example: at the performance state data of the same kind of each AP equipment, as the quantity of the pairing STA of AP equipment, flow size etc., the AC equipment statistics that can simply superpose to the performance data of these equal types is with total performance state data sum of some the AP equipment that obtains appointment; And for some from the network performance status data that each AP equipment returns, the transmission performance that can't intuitively draw, size of channel seizure ratio etc. for example, because each AP equipment can't directly be gathered and add up and draw, thereby also can't directly feed back to AC equipment, thereby for this class performance data, AC equipment then need obtain by computational analysis based on the existing performance state data that get access to.

Particularly, in this step, AC equipment can be unit with the frequency range, to the pairing network performance status data of the AP equipment in the same frequency range, according to the stack statistical analysis of classifying of different data types, to obtain total performance state data of each frequency range.Wherein specifically can comprise:

The network performance status data that AC equipment can at first return based on each AP equipment, carry out the book of final entry at different data types, the record that the data messages such as quantity of the STA that for example quantity that signal strength signal intensity, flow size, speed size, re-transmission or the mistake of each AP are wrapped, and single AP is carried are classified.And in the book of final entry after every type the performance state data of each AP equipment, AC equipment can be at all the AP equipment in the same frequency range, according to different performance data types, to the performance data of the same type of the book of final entry statistics that simply superposes, to count various types of total performance state data in each frequency range.For example stack counts the data messages such as quantity of number, the re-transmission in the same frequency range or the wrong bag of STA included in the same frequency range.

And for the data message that can not adopt the simple superposition statistical method to obtain, for example for the channel seizure ratio of each frequency range, then need obtain by computational analysis based on various types of total performance state data message of this frequency range that counts.Particularly, for the channel seizure ratio ρ of frequency range, can calculate by following formula:

ρ = \frac{Σ_{k = 1}^{n} (T_{fk} + T_{rk} - T_{sk} - T_{ak}) + MIN (T_{s 1}, T_{s 2}, Λ, T_{sn})}{T} %

In above-mentioned formula, ρ is the channel seizure ratio of frequency range, and T is the testing time, and n is the quantity with the AP equipment in the frequency range, T _FkAnd T _RkBeing respectively k AP equipment sends message and receives the time that message takies respectively, T in testing time T _SkBe that k AP equipment receives the shared time of broadcast frame that STA sends, T in testing time T _AkBe that k AP equipment receives the shared time of broadcast frame that other AP equipment sends in the corresponding frequency band in testing time T

Particularly, testing time T is essentially the network performance status data time corresponding of AP equipment feedback, be the blanking time that the network performance status data of twice pair of AP equipment of AC equipment obtains, because the carrying out of the network performance status data of AC Equipment Control AP equipment feedback, thereby this testing time T can be controlled and learn to AC equipment; And n, T _Fk, T _Rk, T _SkAnd T _AkThen can be from the network performance status data of each AP equipment feedback, the statistical method statistics that superposes by above-mentioned classification obtains.

Suppose for the pairing a certain frequency range of AC equipment, comprising the AP equipment of same frequency have n, for k AP, its holding time to this frequency range channel is T so _Fk+ T _Rk-T _Sk-T _Ak, and all STA in this frequency range are when sending broadcast frame, the T that the holding time of this frequency range channel is then collected for each AP _SkMinimum value, i.e. MIN (T _S1, T _S2, Λ, T _Sn).Its reason is: because test is in the middle of the WLAN (wireless local area network) equally with STA, thereby the STA of the broadcast frame STA that receives with to(for) test, other AP equipment in this Local Area Network also can both receive, and therefore need get minimum value.

Step 207, AC equipment be according to default optimisation strategy, and the current running status of the WLAN (wireless local area network) of separating out according to statistical generates the optimization suggestion adaptive with current running status;

Step 208, AC equipment carries out corresponding performance adjustment according to the optimization suggestion that generates to the WAP (wireless access point) of appointment.

The various performance state data and afterwards of AC equipment in statistical has been separated out each corresponding frequency range, based on the pairing various types of performance state data messages of each frequency range, the network operation state in this frequency range can fully be understood and know to AC equipment, thereby can understand the current running status of the WLAN in zone to be tested fully.On this basis, the situation of the current appearance of WLAN (wireless local area network) of this frequency range that is reflected at the performance state data in each frequency range, AC equipment can be according to the optimisation strategy that sets in advance, generate the optimization suggestion adaptive, to be used for that the performance of the WLAN of corresponding frequency band is optimized adjustment with the current network state that analyzes.

Particularly, the optimization of this generation suggestion and corresponding optimizing and revising can comprise following several situation at least:

First kind of situation, AC equipment can be according to the channel seizure ratio size of each frequency range and the quantity of the AP equipment that carries, and whether the intensity of analyzing the co-channel interference that draws each frequency range channel has exceeded the scope that can tolerate.Particularly, in AC equipment, can rule of thumb be respectively the channel seizure ratio of frequency range and the quantity of the AP equipment of correspondence corresponding threshold value is set.And work as for a certain frequency range, if AC equipment is based on the rapid The result of statistics of previous step, the quantity of judging the pairing AP equipment of this frequency range has exceeded the threshold value that is provided with, and the channel seizure ratio of this frequency range is when also having exceeded preset threshold value, AC equipment can conclude that the co-channel interference phenomenon of this frequency range this moment is more serious, need make and optimizing and revising.Therefore based on this situation, AC equipment can generate the quantity that indication reduces the AP equipment in this frequency range, and the optimization suggestion that reduces the power of the AP equipment in this frequency range, to adjust the reference value of regulating automatically in this frequency range in the power algorithm.In the practical application, the threshold value of AP quantity is generally 3 in the same frequency range that is provided with in the AC equipment, and the channel seizure ratio threshold value of the same frequency range that is provided with is generally 50.

And after having generated this optimization suggestion, AC equipment then can be optimized suggestion according to this that generates, this is optimized the AP equipment of appointment in the suggestion, specifically refer to the AP equipment that comprises in a certain frequency range of appointment, optimize and revise accordingly, be specially according to optimizing suggestion, reduce the quantity of the AP equipment in the designated frequency band, and reduce the power of the AP equipment in the designated frequency band.

Second kind of situation, AC equipment can be according to the size of the channel seizure ratio of each frequency range correspondence, and the quantity of the low-speed wireless terminal that comprises in this frequency range, whether analysis draws and occurs in this frequency range owing to the low-speed wireless terminal that comprises too much has influence on the total throughput of channel of this frequency range, and has influence on the phenomenon that the network of STA terminal in this frequency range uses.Particularly, herein the low-speed wireless terminal of indication be in the corresponding a certain frequency range, with AP equipment between be connected the STA equipment that speed is lower than the speed threshold value of setting.Thereby for a certain frequency range, add up the quantity of the low-speed wireless terminal in this frequency range, at first need to know the connection speed of each STA terminal that each AP equipment in this frequency range is entrained, and then whether the connection speed of judging these STA terminals be lower than speed threshold value default in this frequency range, and the STA terminal that only is lower than the speed threshold value just is the low-speed wireless terminal in this frequency range.Each STA terminal then can know from the network performance status data of each AP equipment feedback with the connection speed between the corresponding AP equipment, the network performance status data of each AP equipment feedback comprised its with each STA terminal of carrying between be connected speed.

Further, because in same frequency range, when the low-speed wireless terminal is too much, may influence total throughput of this frequency range channel, but whether can be real exert an influence is also relevant with the size of the channel seizure ratio of this frequency range.For example: when the channel seizure ratio of certain frequency range hangs down, because the channel usage space of this frequency range is bigger, thereby the throughput that too much can't influence other STA in this frequency range of low-speed wireless terminal quantity; And when the channel seizure ratio of certain frequency range is higher,, thereby, can't guarantee that then all STA terminals can both enjoy wireless network well if the low-speed wireless terminal quantity still too much in this frequency range because the channel usage space of this frequency range is less.

Thereby based on above-mentioned principle, the channel seizure ratio of each frequency range correspondence that AC equipment can go out according to statistical computation, and the quantity of the low-speed wireless terminal that comprises according to this frequency range, judge whether the low-speed wireless terminal quantity that comprises in this frequency range has exceeded the scope of pairing, the tolerable maximum low-speed wireless terminal quantity threshold value of channel seizure ratio of this frequency range.Particularly, in the present embodiment, can in AC equipment,, the maximum of corresponding admissible low-speed wireless terminal quantity be set at the channel seizure ratio of various different numerical value.

And behind channel seizure ratio that counts each frequency range and low-speed wireless terminal quantity, AC equipment can judge whether the quantity of the low-speed wireless terminal that comprises in each frequency range has exceeded the pairing maximum of channel seizure ratio of this frequency range, if exceed, AC equipment then can generate the optimization suggestion that indication reduces the quantity of the low-speed wireless terminal that comprises in this frequency range, by reducing the quantity of low-speed wireless terminal in this frequency range, make the quantity of the wireless terminal that comprises in this frequency range meet the pairing maximum of channel seizure ratio of this frequency range.

And after having generated this optimization suggestion, AC equipment then can be optimized suggestion according to this that generates, the AP equipment of correspondence and each STA terminal be connected speed adjustment, for example by the be connected speed of control raising AP equipment with each STA terminal, reduce the quantity of low-speed wireless terminal in the corresponding frequency band, thereby finally improve the service quality of wireless network in this frequency range.

The third situation, AC equipment can also this frequency range inner control messages and the transmission ratio of data message, and it is too frequent whether to occur controlling message in this frequency range of analysis and judgement, and causes the too high phenomenon of channel seizure ratio.Particularly, the quantity forwarded of each the frequency range inner control message (as the beacon frame) that counts in rapid according to previous step and the quantity forwarded of general data message, AC equipment can calculate corresponding various types of control messages in this frequency range, the transmission ratio value of this control message and general data message, thus calculate the pairing channel seizure ratio of this control message.

And according to the channel seizure ratio of respectively controlling the message correspondence in this frequency range that calculates, AC equipment can also be judged this channel seizure ratio and phenomenon greater than the maximum channel occupancy of this default in this frequency range control message correspondence whether occur, promptly judges whether occur controlling the too frequent phenomenon of message transmission in this frequency range.Normally, corresponding to each frequency range, can set in advance in the present embodiment corresponding to each control message, the maximum channel occupancy that this frequency range is allowed when functional, thereby when if the actual channel occupancy of a certain control message of a certain frequency range of AC device discovery is higher than this default maximum channel occupancy, represent the transmission of this control message too frequent, then need to limit and revise the channel seizure ratio of this control message.

Particularly, optimize and revise in order to realize this, in AC equipment, can add up detected control message at this, generate the optimization suggestion that indication reduces the channel seizure ratio of this control message in this frequency range, so that the transmission frequency of correspondence control message is adjusted, make it produce less influence to channel seizure ratio.And after having generated this optimization suggestion, AC equipment is then optimized suggestion according to this that generates, can adjust the channel seizure ratio of the control message of appointment in the designated frequency band in this optimization suggestion, specifically finger is reduced to a certain concrete value with the transmission frequency of formulating the control message in this frequency range, with the channel seizure ratio of the control message that reduces the transmission appointment in the designated frequency band, improve the service quality of wireless network in this frequency range.

Need to prove, because the complexity of WLAN, for various optimal way, can't all enumerate in the present embodiment, and according to the statistic analysis result of AC equipment to the performance state data of each frequency range, AC equipment can be analyzed at various situations, thereby automatically peripheral AP equipment is optimized adjustment according to analysis result, adjust channel or power or carry out the load balancing adjustment, to improve the correlated performance of WLAN.If realizing that AC equipment can also give the alarm by webmastering software under the situation about can't adjust, personnel handle with the prompting webmaster.

Need to prove, in the present embodiment, in order to alleviate the burden of AC equipment, AC equipment is getting access to the network performance status data that each corresponding AP equipment is gathered and added up, and after each network performance status data added up, can the current state of wireless network be analyzed directly according to the data message that counts, generating corresponding optimization suggestion, but the data message that counts can be returned to test with STA or other STA or a certain terminal equipment.Be provided with on the basis of optimizing analysis software at this equipment, this equipment of the data message that receiving and counting goes out can be based on this analysis software, carry out WLAN (wireless local area network) is optimized analysis accordingly according to the data message that counts, can generate corresponding optimization equally and detect.Thereby in this optimization analytical equipment according to being optimized after the suggestion with above-mentioned same method, the optimization suggestion that this equipment will generate again returns to AC equipment, so that AC equipment carries out the performance adjustment according to the optimization suggestion that receives to the AP equipment in the corresponding frequency range, in the processing burden that has alleviated AC equipment, reached purpose of the present invention equally.
