Detailed description of the invention
Below in conjunction with accompanying drawing, the embodiment of the present invention is described in detail.
The embodiment of the present invention one provides a kind of AP fault detection method, be applied to comprised multiple AP andIn the WLAN of at least one AC composition, in this WLAN, AC can with multiple AP wireless connections.In the present embodiment, the Trouble Report information that AC can report according to AP, determines the neighbours that AP detectsWhether fault of AP, particularly, as shown in Figure 2, the AP fault detect side that the embodiment of the present invention one providesMethod can comprise the following steps:
Step 201, AC receives the Trouble Report information that reports of AP, described in described Trouble Report information isAP reports the information of described AC when the neighbor AP fault that described AP need to detect detected, described inTrouble Report information is used to indicate described neighbor AP fault.
In this step, AP can detect one or more AP, the neighbor AP that AP need to detectCan be one or more. Wherein, the neighbor AP that AP need to detect, can be specifically predefined,Or by AP oneself selected, or be handed down to AP by AC, in the present embodiment with AC issue intoExample describes.
If it will be understood by those skilled in the art that AP only detect a neighbor AP (be AC to AP onlyIssue the neighbor AP that needs detect), AC receives after Trouble Report information, just can basisThe information self issuing, determines the neighbor AP of the fault that this AP detects; If it is multiple that AP detects simultaneouslyNeighbor AP (being that AC issues multiple neighbor AP that need detection to AP), the fault report that AP sendsIn announcement information, should carry the identification information of the neighbor AP breaking down, such as neighbor AP is usedBSSID(BasicServiceSetIdentifier, basic service set identification) etc., so that the judgement of AC equipmentThere is fault in which AP equipment specifically.
Step 202, described AC, according to described Trouble Report information, determines described neighbor AP fault.
Corresponding to step 201, if AC only detects for each AP distributes respectively and issued needsNeighbor AP, the neighbor AP that each AP need to detect only has one, AC is receiving APAfter the Trouble Report information sending, can determine this Trouble Report according to the AP that sends this Trouble Report informationThe AP that information pointer is right, the i.e. AP of fault. If AC is for each AP has distributed, more than one AP doesFor its neighbor AP that need to detect, AC need to be according to the mark of the AP carrying in Trouble Report informationInformation is determined the AP that this Trouble Report information pointer is right.
In the present embodiment, after making AP judge that neighbor AP breaks down, send Trouble Report to ACInformation, notices AC this neighbor AP and breaks down, can avoid each AP to AC frequent send a large amount of,Useless heartbeat message, has saved the bandwidth resources between AP and AC. Simultaneously also without AC to eachWhether AP breaks down judges, has reduced the work load of AC. And, in the embodiment of the present invention,AP reports AC immediately detecting after neighbor AP fault, makes AC equipment can know in time this neighboursAP fault, the time of having reduced AC and detect AP fault, improves AP fault detect efficiency. This realityExecute example in reaching quick raising AP fault detect efficiency, can avoid the carrying out between AP and ACThe message interaction quantity of fault detect, saves bandwidth resources.
Another one embodiment bis-of the present invention provides a kind of AP fault detection method, be applied to comprised manyThe WLAN of individual AP and at least one AC composition, in the embodiment of the present invention two, AP can be in real time to needsThe neighbor AP detecting detects, and in the time neighbor AP fault being detected, real-time report is to AC, withMake AC determine whether fault of this neighbor AP, particularly, as shown in Figure 3, the embodiment of the present invention two is carriedThe AP fault detection method of confession can comprise the following steps:
Step 301, AP determines the neighbor AP that self need to detect, and described in judging and receiving apart from the last timeThe time of the wireless signal that neighbor AP sends, while exceeding preset value, is determined described neighbor AP fault.
Those skilled in the art can be appreciated that the wireless signal here specifically can refer to radio communication systemWireless communication signals in system, such as beacon frame etc. Particularly, the wireless signal in the present embodiment canTo comprise Frame for carrying actual data content and mutual or time synchronized for carrying out stateBeacon frame, if AP does not receive within the default time, the neighbor AP that self need to detect sendsAny wireless signal, thinks and within time corresponding to this preset value, needs the neighbor AP detecting outwards not haveSend any wireless signal, now, AP just can determine described neighbor AP fault. In actual applications,Each AP in WLAN must according to the default cycle (this default cycle is set voluntarily by user,Generally between 20-1000ms) outwards send beacon frame and carry out the synchronous of wireless network connection, or logicalAccuse the status information of self. Therefore, in the preferred embodiment of the present invention, if AP is when defaultIn do not receive need detect neighbor AP send beacon frame, can judge neighbor AP fault.
In concrete application, the neighbor AP that can make AP detect for needs arranges corresponding timer, andReceiving after the wireless signal of neighbor AP transmission, timer corresponding this neighbor AP is set to 0. AsFruit AP does not receive the wireless signal of certain neighbor AP transmission self detecting, this neighbor AP alwaysThe counting of corresponding timer can increase gradually until exceed preset value, and now, AP thinks at this preset valueIn the corresponding time period, this neighbor AP does not send wireless signal, and now, this AP thinks this neighbor APFault.
Step 302, described AP is to described AC reporting fault report information, and described Trouble Report information is usedIn the described neighbor AP fault of instruction, so that described AC determines described neighbours according to described Trouble Report informationAP fault.
In the embodiment of the present invention, by AP is being judged after neighbor AP device fails, on ACReport fault message, avoids each AP to a large amount of, the useless heartbeat message of the frequent transmission of AC, savesBandwidth resources between AP and AC, the work load of reduction AC. In the while embodiment of the present invention, canAllow not receive by turning down AP the mode of the Preset Time value that neighbor AP allows, improve APThe promptness of fault detect.
Based on above-described embodiment one or two, the embodiment of the present invention three also provides another AP fault detectMethod, in the embodiment of the present invention, supposes that described wireless signal is specially beacon frame, and supposes that AP2 is AP1The neighbor AP of required detection, as shown in Figure 4, can comprise the steps:
Step 401, AP1 judge apart from the last time that receives the beacon frame that neighbor AP 2 sends whetherExceed preset value; If so, turn to step 402, if not, process ends.
In the embodiment of the present invention, can be by AP for example, at Preset Time (being above-mentioned preset value), 3 beaconsIn frame period, whether receive the beacon frame judgement of whether breaking down as neighbor AP that neighbor AP sendsStandard, like this, if AP in Preset Time, does not receive the beacon frame that neighbor AP sends, justCan determine neighbor AP fault.
Step 402, AP1 sends Trouble Report information to AC equipment.
Step 403, AC receives the Trouble Report information that AP1 sends, and determines according to Trouble Report informationAP2 fault.
Step 404, AC issues replacement notification message to AP1, has wherein carried the front institute of AP2 fault and has madeWith BSSID.
In practical application, the upper BSSID that can record the actual use of each AP of AC. In this step, ACIssue to replace in notification message to AP1 and carried the BSSID that all AP2 use before fault, for tableShow neighbor AP, i.e. AP2 fault, instruction AP1 replaces AP2 to send the client of information to access AP2,Notice AP2 fault.
Step 405, AP1 receives after the replacement notification message of AC transmission, with used before AP2 faultEach BSSID is as BSSID Broadcast Fault information, and the client of noticing access AP2 reselects APAccess.
Wherein, fault message is used to indicate each client neighbours' fault of access AP2, like this, and access AP2Each client just can reselect new AP access of radio network, avoid communication disruption.
After this step, the client that is linked into AP2 for those, can receive AP1 transmissionBeacon frame after enter roaming state, select new AP again to access. And be not linked into for thoseThe client of AP2, unaffected.
In the embodiment of the present invention three, by AC is being judged after AP2 fault, send to replace to AP1 and lead toKnow message, notice AP1 broadcast is used for noticing the disabled fault message of AP2, can make client at itAfter the AP accessing breaks down, automatically select other AP access, improved user's access and experienced,Ensure the stability of network service.
On the basis of the embodiment of the present invention one or two, the AP fault detect side that the embodiment of the present invention four providesIn method, can also be by AC automatically for AP distributes its neighbor AP that will detect, in the embodiment of the present inventionFour one that provide preferred embodiment in, can make as follows AP determine that self will detectNeighbor AP, as shown in Figure 5, can comprise the steps:
Step 501, AP1 detects each adjacent AP, obtains the detection letter to each adjacent APBreath, described detection information comprise the wireless signal that each adjacent AP of receiving sends RSSI andThe identification information of adjacent AP.
The identification information of the adjacent AP here uses can send wireless signal for adjacent AP timeBSSID, the BSSID carrying in the wireless signal that AP receives, or can also be this BSSIDCorresponding bridge MAC Address. Below only take in the wireless signal receiving taking the identification information of adjacent APThe BSSID of band describes.
For convenience of description, in each step after this step of the embodiment of the present invention, all with described simultaneouslyWireless signal is that beacon frame describes.
Step 502, AP1 by the detection information reporting to each adjacent AP to AC.
In practical application, (be less than default if the signal strength signal intensity of certain beacon frame that AP1 receives is weakValue), the AP of this beacon frame of explanation transmission is probably distant from AP1, and is not suitable for being monitored by AP1,Therefore the one of the embodiment of the present invention preferred embodiment, is detecting after each beacon frame AP1,According to beacon frame or the selection signal strength signal intensity of strong (being greater than preset value) of RSSI selection portion sub-signal intensityThe strongest several beacon frames and corresponding BSSID thereof report AC.
Report two AP(to be respectively AP2, AP3 so that AP1 is actual below) beacon frame that sendsBSSID and RSSI describe. Certainly in practical application, for fear of BSSID corresponding to certain APSituation about not reported by other AP, the quantity of the BSSID also can AP1 reporting is set to oneLarger value, the present embodiment does not limit.
Step 503, AC receives the detection information to adjacent AP that each AP reports, and according to receptionTo detection information in identification information and the corresponding RSSI of the adjacent AP that carries be each AP distributionNeed the neighbor AP detecting.
In this step, AC is receiving after the BSSID of AP1 transmission, and need to determine according to BSSID shouldThe adjacent AP that BSSID is corresponding, i.e. AP2 or AP3, recording respectively adjacent AP is that AP2 and AP3 send outThe RSSI of the beacon frame sending, and report the AP of the detection information of this AP2 and AP3, i.e. AP1. PressAccording to this mode, AC records each adjacent AP, the RRSI of each neighbor AP that each AP reports, andReport the corresponding relation between the AP of each neighbor AP, like this, just can be according to each AP for sameThe RSSI that individual adjacent AP reports, distributes to this same adjacent AP on this same adjacent APThe strongest AP of RSSI of report, such as reporting in the AP of detection information at all BSSID for AP2,If the RSSI corresponding to AP2 that AP1 reports is the strongest, AP2 is distributed to AP1, using asThe neighbor AP that AP1 need to detect.
Certainly in practical application, with regard in order to realize with regard to technical scheme of the present invention, AC might not pass throughAforesaid way is that AP distributes its neighbor AP that need to detect, the BSSID correspondence that also AP can be reportedAP directly distribute to the neighbor AP that reports the AP of this BSSID need to detect as AP1, orThe neighbor AP of the required detection of upper directly each AP of configuration of AC is also handed down to each AP.
For convenience of description, in the present embodiment, being only assigned to AP1 using AP2 needs to detect as AP1Neighbor AP describe.
Step 504, AC sends neighbor advertisement message to AP1, has wherein carried the identification information of AP2.
Accordingly, the identification information carrying in the neighbor advertisement message that in this step, AC issues to AP1 canThink the BSSID using before AP2 fault, or the bridge MAC Address of AP2.
Step 505, AP1 receives the neighbor advertisement message that AC sends, according to carrying in neighbor advertisement messageAP2 identification information determine need to carry out fault detect to AP2.
After this step, if AP2 breaks down, no longer outwards broadcast beacon frame, can trigger as stepThe AP fault detect flow process of rapid 201-step 202 or step 401-step 406. Do not repeat them here.
In embodiments of the present invention, be each AP distribution neighbours by the RSSI information reporting according to APInformation, can ensure that each AP is detected by rational AP.
In above-mentioned arbitrary embodiment, the Trouble Report information that AC reports according to AP is determined neighbor AP fault,Specifically can be in the following manner:
Described AC, according to described Trouble Report information, determines the described neighbour of breaking down that described AP detectsOccupy AP, and determine that described AC receives the fault of the described neighbor AP fault of instruction that other AP reportWhen report information, determine described neighbor AP fault;
Or described AC receives being used to indicate of predetermined number that described AP reports in Preset TimeWhen the Trouble Report information of described neighbor AP fault, determine described neighbor AP fault.
Particularly, in the time that multiple AP detect same AP, AC receive an AP report forAfter the Trouble Report information of one adjacent AP, AC can judge whether to have received other AP for this phaseThe Trouble Report information of adjacent AP, if so, judges this AP fault, if not, preserve this eventBarrier report information; Or AC receives the Trouble Report for neighbor AP that AP reports for the first timeAfter information, do not determine immediately neighbor AP fault, preserve this Trouble Report information, if in the default timeInside again receive the Trouble Report information that this AP reports, think this neighbor AP fault. By thisMode, can avoid causing the erroneous judgement of AC to its neighbor AP fault because the mistake of AP reports. Certainly,It will be appreciated by persons skilled in the art that above-mentioned preferred embodiment in, also can make AC receiveJust think these neighbours after the Trouble Report information for same neighbor AP that two AP report to exceedingAP fault, or make that AC receives in default time range that same AP reports for same neighbourOccupy AP Trouble Report information and exceed twice, just think that this neighbor AP reports. Above-mentioned embodiment is only thisApply for preferred embodiment, and should not be construed as the restriction to the embodiment of the present invention.
Below in conjunction with concrete application scenarios, AP fault detection method provided by the invention is said in detailBright, suppose in the embodiment of the present invention five, in WLAN, comprise AP1, AP2, AP3, AP4, AP5 fivePlatform AP and an AC, be connected by LAPP between AC and each AP, has 3 on each APAt the BSSID of use, as shown in Figure 6, the preferred embodiment of AP fault detection method provided by the inventionSchematic flow sheet can comprise the steps:
Step 601, the signal that AP1 detects current each beacon frame that can receive according to predetermined period is strongDegree RSSI.
In practical application, this predetermined period can be set arbitrarily as required by keeper. But due to respectivelyIndividual AP disposes, and possibility extensive, high-frequency variation is less, for fear of the burden causing to AP,Can a suitable larger value be set for this predetermined period.
Step 602, AP1 reports the RSSI of each beacon frame detecting and corresponding BSSIDAC。
In this step, suppose that AP1 selects two RSSI the strongest detecting after the RSSI of each beacon frameAnd corresponding BSSID reports. For convenience of description, in following steps, all suppose what AP1 reportedBSSID belongs to respectively AP2 and AP4.
In practical application, can also make AP that the RSSI detecting and corresponding BSSID are reported to ACAfter, judge that this need to report several (such as two the strongest) whether RSSI and corresponding BSSIDWith the last time report identical, if the judgment is Yes, do not report, if not, report.So just can avoid in the space at this AP place AP to dispose while changing reports and detects letter to ACBreath, saves the bandwidth resources between AC.
Particularly, the adjacent AP's that the AP in network can detect oneself according to the interval of time T 0Detect information reporting to AC, this adjacent AP refers in particular to the in running order AP being connected on this AC.Wherein, the detection information reporting specifically can comprise: the MAC Address of adjacent AP, nearest 3 continuous lettersThe RSSI mean value of mark frame (Beacon).
The message format of the detection information that AP reports can be by following form:
Wherein, T is self-defined message type, has preserved the message content of AP notice AC in (E); MsgElement is the content of concrete interactive information; The relevant information of the adjacent AP that E inclusion test arrives. AC receivesAfter this message, need to send response message to AP, and E is set to sky.
Step 603, AC records RSSI corresponding to BSSID that each AP reports, and searches each BSSIDCorresponding AP.
In practical application, AC can record corresponding relation as shown in table 1.
Table 1
As shown in table 1, AP1 and AP3 have reported two BSSID of AP2, MAC21 and MAC22,Wherein, RSSI corresponding to MAC21 that AP1 reports is that 50db(is that AP1 receives AP2 transmissionThe BSSID of beacon frame is MAC21, and the RSSI that receives this beacon frame is 50db), AP3 reportsThe RSSI of MAC22 is 40db. In table 1, be only a kind of ideal situation, the BSSID that each AP reportsJust do not conflict, and do not belong to same AP, in practical application, the BSSID that AP reports and correspondence thereofThe situation of RSSI may be more than the complexity shown in table 1, corresponding, need to select comparatively complicated calculationMethod is carried out the distribution of neighbor AP, and in the embodiment of the present invention, only associative list 1 describes.
Step 604, the RSSI that AC reports according to each AP is each AP distribution neighbor AP, and willThe identification information of the neighbor AP of distributing for each AP be carried in neighbor advertisement message, send to correspondingAP。
For AP1, the signal strength signal intensity that AP3 receives its beacon frame is the strongest, therefore, using AP1 asThe neighbor AP that AP3 need to detect sends to AP3. For AP2, the signal that AP1 receives its beacon frame is strongSpend the byest force, therefore, the neighbor AP that need to detect AP2 as AP1 sends to AP1. Accordingly,AP3 is distributed to the neighbor AP that AP4 need to detect as AP4, using AP4 distribute to AP5 asThe neighbor AP that it need to detect, distributes to using AP5 the neighbor AP that AP2 need to detect as it. Enter oneStep, report for fear of the mistake of AP, same AP can also be distributed to multiple AP as itNeed the neighbor AP detecting, and other AP is detected this AP. In the embodiment of the present invention,Suppose that AP2 has also distributed to the neighbor device that AP3 need to detect as AP3.
In actual applications, AC also can judge this BSSID institute receiving after the BSSID that AP reportsThe AP that whether manages for self of AP of ownership, if not, this BSSID and corresponding abandonedRSSI, whether the RSSI that can also make AC judge that same AP reports is all less than preset value simultaneously, asBe really, illustrate that this AP is probably far away with the distance of other all AP, the network planning is unreasonable,Now AC sends warning information, and selects maximum several RSSI that this AP reports and correspondingBSSID carries out subsequent treatment. In actual mechanical process, for be embodied as each AP distribute identical orThe neighbor AP that fair amount need to detect, distributes to AP to report the RSSI of this AP the strongest followingWhen the principle of neighbor AP that AP detects as needs, may also need to calculate in conjunction with mathematics such as exclusive methodsMethod, does not repeat them here.
Preferably, in the embodiment of the present invention, can make AC is that each AP distributes maximum two neighbor APThe neighbor AP that need to detect as it ensures that each AP is assigned at most two neighbor AP and does simultaneouslyFor these two neighbor AP that neighbor AP need to detect.
In practical application, the identification information of the AP carrying in neighbor advertisement message can be used by this APBSSID, or the bridge MAC Address of this AP. In the embodiment of the present invention, only with neighbor advertisement messageIn the identification information of the AP that carries describe for the BSSID that this AP uses, and hypothesis is handed down toThe BSSID(MAC21 that the identification information that carries AP2 in the neighbor advertisement message of AP1 is AP2),Be handed down to and in the neighbor advertisement message of AP3, carry another BSSID that the identification information of AP2 is AP2（MAC22）。
Particularly, AC can following form issues neighbor advertisement message to AP:
Wherein, T0 is self-defined message type, has preserved in the message of AC notice AP in (E0)Hold; MsgElement is the content of concrete interactive information; The concrete message that E0 comprises AC notice AP,The MAC Address that comprises two (or one) neighbor AP that this AP should intercept.
Further, carrying out before this step, the AP1 that can also make AC judge to receive reportsWhether detection information is identical with the detection information of the last AP1 receiving, if so, and without carrying outRedistribute, if not, need to redistribute.
Step 605, AP1 receives the neighbor advertisement message that AC sends, and obtains in neighbor advertisement message and carriesThe mark MAC21 of AP2.
Step 606, AP1 arranges the timer for MAC21, and the initial value of this timer is 0, andThis timer is set to 0 receiving after the beacon frame that BSSID is MAC21.
Accordingly, AP3, receiving after the neighbor information of AC transmission, also can arrange meter for MAC22Time device, this timer is set to 0 receiving after the beacon frame that BSSID is MAC22.
After step 606, suppose that AP2 breaks down, AP2 can not send beacon frame, thereby leadsCause timer expired corresponding to MAC21 arranging in AP1, the AP that embodiment of the present invention five providesThe flow process of fault detect also comprises the steps.
Step 607, AP1 judges the timer expired that MAC21 is corresponding, sends Trouble Report letter to ACBreath, has carried the BSSID(MAC21 that AP2 uses in this Trouble Report information).
Wherein, AP can send Trouble Report information to AC by following form:
Wherein, T1 is self-defined message type, has preserved in the message of AP notice AC in (E1)Hold; MsgElement is the content of concrete interactive information; The neighbor information that E1 comprises AP notice AC.
AC does not need to respond after receiving this message; Receive that another one AP has also reported this neighbours' event simultaneouslyBarrier, confirms this AP fault, carries out subsequent treatment; If do not received, if received after stand-by period TArrive the fault message for the second time of identical AP report, confirmed this AP fault, if do not received,Abandon primary Trouble Report information, be left intact.
Step 608, AC receives the Trouble Report information that AP1 sends, and obtains in Trouble Report information and carriesBSSID(MAC21).
Step 609, whether AC determines that the AP that MAC21 is corresponding is AP2, and receive before judgementThe Trouble Report information of AP3 for this AP2, if so, turn to step 610, if not, turnTurn to step 612.
In this step, if so, illustrate that AP3 has also detected the fault of AP2, and reported correspondingFault message. Now, AC confirms AP2 fault, in this way, can avoid sending out because of AP1Raw bug reporting fault information, causes the erroneous judgement of AC.
Step 610, AC issues replacement notification message to AP1, has wherein carried two BSSID of AP2,These two BSSID correspond respectively to MAC21 and MAC22.
In practical application, also can make MAC21 and MAC Address corresponding to MAC22 issue respectivelyGive AP1 and AP3, or MAC21 and MAC Address corresponding to MAC22 are handed down to AP1 simultaneouslyAnd AP3.
Step 611, AP1 receives the replacement notification message that AC sends, taking MAC21 and MAC22 asBSSID Broadcast Fault information, notices the interior client mac 21 of WLAN and MAC22 unavailable.
In practical application, can make AP1 by the value amendment of two BSSID that do not using of selfFor MAC21 and MAC22, and make AP1 use respectively two amended BSSID outwards to broadcast useIn noticing MAC21 and the disabled beacon frame of MAC22. Wherein, the beacon frame of broadcast can comprise and containsBSS(BasicServiceSet) Loadelement(basic service set load unit) and VendorSpecificAppointed information unit of informationelement(producer) etc. the information word of type, wireless client is according to connecingThis type of information territory comprising in the beacon frame (Beacon) of receiving can select suitable AP to go roaming or heavyNew associated.
After this step, client is receiving after the fault message of AP1 broadcast, think MAC21 andThe BSSID that MAC22 is corresponding is unavailable, and the client that is linked into AP2 can reselect otherBSSID accesses.
Step 612, the Trouble Report information of AC recording needle to AP2.
In the present embodiment AP fault detect, when certain AP fault in network, AC can be when the shortestIn confirm fault AP, and can take appropriate measures, can effectively guarantee client access stability andContinuity, has improved to greatest extent user's access and has experienced, and has improved the stability of any wireless network servicesAnd reliability.
