If Interference Detection is carried out at A points, since A points are except dashed circle range, so can't detect access point The interference of equipment 2.But in fact, although the user equipment at C points is in the WLAN of access point apparatus 1, but since it is in The region that coverage area is intersected, and air line distance of the C points away from B points is obviously smaller than the air line distance away from A points.That is due to Distance is closer to so if two access point apparatus have chosen cochannel or phase Adjacent Channel, C points receive access point apparatus 2 Signal instead can be stronger, and interference will be extremely serious；And this interference can not be found by the Interference Detection at A points.

It can be seen that existing WLAN Interference Detections and management have a defect that, examined by access point apparatus central point It surveys, testing result can not accurately match with the practical interference being subject to of user equipment.

Specific implementation mode

In order to make those skilled in the art more fully understand the scheme of the embodiment of the present invention, below in conjunction with the accompanying drawings and implement Mode is described in further detail the embodiment of the present invention.

Present invention is generally directed to detections and management that the access point apparatus that operator divides into is interfered.By it is above-mentioned Know, the access point apparatus that operator divides into very likely is interfered by other access point apparatus, and existing Interference Detection exists Testing result is inaccurate under certain specific conditions.The purpose of the present invention is to solve the above problems.Several embodiments below It is placed under the application scenarios.

A kind of interference detection method is disclosed in the present embodiment.The method is to solve to carry out interference inspection at access point apparatus The technical issues of survey, testing result can not accurately be consistent with the practical disturbed condition being subject to of user equipment, and take profit The technical solution of Interference Detection is directly carried out with user equipment.User equipment need to coordinate cellular network in the present embodiment the method And detection process is completed in the base station of cellular network.Shown in Fig. 2, the present embodiment the method specifically includes following step Suddenly：

Step 201, user equipment receive the detection instruction of base station.

In the present embodiment, user equipment is located at a certain specific position, and directly carries out Interference Detection at this location, so The testing result measured accurately illustrates actual disturbed condition at the position.

The base station is cellular network base station, and the cellular network namely refers to the 2G/3G/4G that operator provides at this stage Network, such as GSM network or cdma network or LTE network.Base station described in the present embodiment can be understood as the base of broad sense It stands, such as the evolution base station in LTE network and the base station in 2G/3G/4G networks or base station controller, in this implementation Within the scope of base station described in example.May include multiple operators within the scope of the cellular network that one base station is provided The access point apparatus divided into is required to the Interference Detection of these access point apparatus the base station is coordinated to complete.In this step In, the communication between the base station and user equipment is to be realized by the cellular network that base station provides；This also avoids existing During Interference Detection, relevant communication is completed using WLAN, and influences the defect of WLAN normal uses.That is this implementation Method does not have an impact the normal work of WLAN completely in the detection described in example.

Include the information of access point apparatus to be detected in the detection instruction；It can specifically include access point apparatus to be detected Title, access point apparatus ID to be detected or channel number to be detected etc..In general channel to be detected is exactly access to be detected The channel that point uses.If not including channel number to be detected, user equipment voluntarily searches for institute according to access point apparatus ID State the number of channel used in access point apparatus to be detected.Testing index can also be arranged in detection instruction reports thresholding, Whether the communication to define access point apparatus to be detected is disturbed.Report thresholding subsequently will specifically about Testing index It is bright.

The core concept of the present embodiment is to realize the Interference Detection process using user equipment itself；And this reality It applies base station in example and only plays control action for user equipment in detection process, and be not involved in actual detection.So User equipment described in step 201 receives the detection instruction of base station, and then starts subsequent testing process.

Step 202, user equipment refer to according to the detection in the communication channel of detection command detection access point apparatus to be detected Mark, obtains Testing index information.

User equipment then instructs according to detection after receiving detection instruction and starts testing process.Specifically, user sets The access point apparatus information to be detected for including in the standby instruction according to detection and channel information to be detected, search channel to be detected, And the signal intelligence in channel to be detected is detected.In addition, the interference in channel to be detected not only may be to be checked Survey channel itself, it is also possible to come from adjacent channel.It is advantageous to, user equipment is also pair Chong Die with channel frequency to be detected Adjacent channel is detected；To ensure the comprehensive and accuracy of Interference Detection.

It, will be according to Testing index information specifically for defining with the presence or absence of interference in detection process.For to be checked Survey access point apparatus and channel to be detected, other near it of user equipment searches there may be the access point apparatus of interference or Channel, and measure in channel to be detected Testing index from access point apparatus to be detected and from connecing there may be interference Enter the Testing index of point device or channel；Testing index information is finally obtained, and judges these accesses there may be interference Whether point device or channel really produce interference to access point apparatus to be detected and channel to be detected.

In the present embodiment, using Testing index by as weigh disturbed condition quantization parameter；Signal intensity rate or difference, The indexs such as signal quality ratio or difference, path loss or available frame count ratio are equal may to be used as Testing index.

If it is that detection comes from access to be detected in the channel using signal intensity ratio or signal quality ratio as Testing index The signal strength of point device（Or quality）With the signal strength from other access point apparatus（Or quality）Ratio or difference, with This ratio or difference are as Testing index information, with annoyance level of the Testing index Information definition from other access point apparatus.

If using available frame count ratio as Testing index, available frame count ratio has following two calculations：First, will believe Frame number from access point apparatus to be detected in road is made as available frame count, and by the ratio of totalframes in available frame count and channel For available frame count ratio, which is defined into annoyance level as Testing index information.It is another be will be in channel to be detected The frame number of access point apparatus is as available frame count, using other frame numbers in channel as non-effective frame number, by available frame count with it is non- The ratio of available frame count defines annoyance level as available frame count ratio, using the ratio as Testing index information.

Step 203, according to Testing index information and it is preset report thresholding, judge whether to need to report examining report；When Need to report then user equipment to report examining report.

It is pre-set in detection instructs in the present embodiment and reports thresholding, user equipment reports thresholding and detection by comparing Indication information determines whether to report examining report, for example, it is described report thresholding to indicate, when Testing index information above or below The thresholding, then it is assumed that there is interference in access point apparatus to be detected and channel to be detected at this time, user equipment need to be reported to base station Testing result, so that base station executes subsequent processing.

And for different Testing index, it is corresponding that thresholding is reported to be also required to be respectively set.It can be advance in the present embodiment Selected one or more Testing index, and thresholding is reported according to the setting accordingly of different Testing index, and according on corresponding Report thresholding judges Testing index information respectively.In the present embodiment, different Testing index corresponds to the different thresholdings that reports, institute To report thresholding may be upper limit thresholding with described, it is also possible to offline thresholding.For upper limit thresholding, when beyond thresholding is reported on Report examining report.For offline thresholding, examining report is reported less than when reporting thresholding.In short, as long as Testing index information is less than Foot reports the limitation of thresholding, then reports examining report.

For example, being upper limit thresholding when reporting thresholding, the Testing index information of user equipment detection has exceeded preset report Thresholding, then it is assumed that there is interference in the communication channel of access point apparatus to be detected at this time；User equipment judges in this, as detection As a result, and by this judging result reporting base station in the form of examining report.Still lead to about the communication process of examining report is reported The cellular network for crossing base station offer is completed.

In addition, may include following content in the examining report：

The location information of location of user equipment, user equipment can be absolute location information, for example be latitude and longitude information；Or Person is relative position information, such as relative to the position of cellular network；User can measure the signal of cellular network, pass through measurement Cellular network signals determine its relative position in cellular networks.

Testing index and Testing index information；It has been given in foregoing teachings about Testing index and Testing index information Explanation has been given, has been not repeated narration herein.

The information of access point apparatus to be detected, the information are consistent with the access-in point information to be detected for including in detection instruction； The detection data of access point apparatus to be detected is included in the Testing index information and is reported together.

The information of relationship access point apparatus, by the description above-mentioned for reporting thresholding it is known that working as Testing index information The limitation for reporting thresholding is not met（It is more than or to reach thresholding）, then examining report is reported.And according to for calculating Testing index The measured data of information can learn specifically result in Testing index information from which access point apparatus signal or data frame It is unsatisfactory for reporting the limitation of thresholding, the access for the limitation for causing Testing index information to be unsatisfactory for thresholding is can consider in the present embodiment Point device, which has access point apparatus to be detected, to be interfered.User equipment according to Testing index information and it is preset report thresholding, really After the access point apparatus for having determined the limitation for causing Testing index information to be unsatisfactory for thresholding, simultaneously as relationship access point apparatus Report the information of relationship access point apparatus, such as the title of relationship access point apparatus and address.For relationship access point apparatus Specific detection data will be included in the actually detected value information and report together.Base station is set according to relationship node in the present embodiment Standby information can learn that the interference which access point apparatus user equipment nearby has treat detection device is stronger.

Actually detected value information；The actually detected value refers to the real data number being detected to Testing index Value；The practical detection value information of surveying may include the measured value for access point apparatus Testing index to be detected, can also wrap Include the measured value for relationship access point apparatus Testing index.

Free channel information, while the information for the idle channel that interference is not present is reported, so that base station is in access to be detected Point device is deposited makes the adjustment such as subsequent channel change in case of interferers.

So far, the Interference Detection flow of WLAN is completed in user equipment side, is accurately obtained the dry of a certain specific location Disturb situation.
