Embodiment
In order that those skilled in the art more fully understand the scheme of the embodiment of the present invention, the embodiment of the present invention is described in further detail with embodiment below in conjunction with the accompanying drawings.Present invention is generally directed to the detection and management that the access point apparatus that operator divides into is disturbed.By above-mentioned, it is known that the access point apparatus that operator divides into very likely is disturbed by other access point apparatus, and testing result is not accurate enough in certain special cases for existing Interference Detection.The purpose of the present invention is to be to solve the above problems.Some embodiments are placed under the application scenarios below. A kind of interference detection method disclosed in the present embodiment.Methods described takes the technical scheme that Interference Detection is directly carried out using user equipment to solve to carry out Interference Detection, the technical problem that its testing result accurately can not be consistent with the actual disturbed condition being subject to of user equipment at access point apparatus.User equipment need to coordinate the base station of cellular network and cellular network to complete detection process in the present embodiment methods described.Referring in particular to shown in Fig. 2, the present embodiment methods described specifically includes following steps：
Step 201, user equipment receive the detection instruction of base station.
In the present embodiment, user equipment is located at a certain ad-hoc location, and directly carries out Interference Detection at the position, so the testing result measured accurately illustrates disturbed condition actual at the position.
The base station is cellular network base station, and the cellular network namely refers to the 2G/ 3G/4G networks that operator provides at this stage, such as GSM network or cdma network, or LTE network.Base station described in the present embodiment can be understood as base station or base station controller in the evolution base station in the base station of broad sense, such as LTE network, and 2G/ 3G/4G networks, in the present embodiment within the scope of the base station.Within the scope of the cellular network that one base station is provided, the access point apparatus that may be divided into comprising multiple operators, the Interference Detection for these access point apparatus is required to coordinate the base station to complete.In this step, the communication between the base station and user equipment is that the cellular network provided by base station is realized；During existing Interference Detection, related communication is completed using WLAN, and the defect for influenceing WLAN normally to use.That is normal work of the method described in the present embodiment in the detection completely not on WLAN produces influence.
The information of access point apparatus to be detected is included in the detection instruction；Access point apparatus title to be detected, access point apparatus I D to be detected or channel number to be detected etc. can specifically be included.In general channel to be detected is exactly the channel that access point to be detected is used.If not comprising channel number to be detected, the numbering of user equipment channel according to used in access point apparatus ID voluntarily searches for the access point apparatus to be detected.Whether Testing index can also be set in detection instruction reports thresholding, be disturbed with the communication for defining access point apparatus to be detected.Thresholding is reported subsequently to will be explained on Testing index.
The core concept of the present embodiment is using user equipment to realize described Interference Detection process in itself；And the control action for user equipment is only played in base station in detection process in the present embodiment, and it is not involved in actual detection.So the user equipment described in step 201 receives the detection instruction of base station, and then start follow-up testing process.
In the communication channel of step 202, user equipment according to detection command detection access point apparatus to be detected Testing index, obtain Testing index information.
User equipment then starts testing process after detection instruction is received according to detection instruction.Specifically, user equipment searches channel to be detected, and the signal intelligence in channel to be detected is detected according to the access point apparatus information to be detected and channel information to be detected that are included in detection instruction.In addition, the interference in channel to be detected not only may be from channel to be detected in itself, it is also possible to come from adjacent channel.It is advantageous to, a user equipment also pair adjacent channel overlapping with channel frequency to be detected is detected；To ensure the comprehensive and accuracy of Interference Detection.
It is specific for defining with the presence or absence of interference in detection process, will be according to Testing index information.For access point apparatus to be detected and channel to be detected, other near it of user equipment searches measure in channel to be detected Testing index from access point apparatus to be detected and from there may be the Testing index of the access point apparatus of interference or channel there may be the access point apparatus of interference or channel；Testing index information is finally given, and judges whether these really generate interference there may be the access point apparatus of interference or channel to access point apparatus to be detected and channel to be detected.
In the present embodiment, the quantization parameter for weighing disturbed condition will be used as using Testing index；The index such as signal intensity rate or difference, signal quality ratio or difference, path loss or available frame count ratio is possibly as Testing index.
It is signal intensity of the detection in the channel from access point apparatus to be detected if being used for Testing index with signal intensity ratio or signal quality（Or quality）With the signal intensity from other access point apparatus（Or quality）Ratio or difference, using this ratio or difference as Testing index information, with annoyance level of the Testing index Information definition from other access point apparatus.
If being used for Testing index with available frame count, available frame count ratio has following two calculations：One is that the ratio is defined into annoyance level as Testing index information as available frame count ratio as available frame count, and using the ratio of totalframes in available frame count and channel using the frame number from access point apparatus to be detected in channel.Another is to regard the frame number from access point apparatus to be detected in channel as available frame count, it regard other frame numbers in channel as non-effective frame number, using the ratio of available frame count and non-effective frame number as available frame count ratio, the ratio is defined into annoyance level as Testing index information.
Step 203, according to Testing index information and it is default report thresholding, judge whether to need to report examining report；When needs report then user equipment to report examining report.
Pre-set in the present embodiment in detection instruction and report thresholding, user equipment reports door by comparing Limit and Testing index information determine whether to report examining report, it is such as described to report thresholding to represent, when Testing index information is above or below the thresholding, then think there is interference in now access point apparatus to be detected and channel to be detected, user equipment need to report testing result to base station, so that base station performs subsequent treatment.
And for different Testing index, it is corresponding to report thresholding to be also required to set respectively.One or more Testing index can be preselected in the present embodiment, and setting reports thresholding accordingly according to different Testing index, and report thresholding to judge Testing index information respectively according to corresponding.In the present embodiment, what different Testing index correspondence was different reports thresholding, so described report thresholding to be probably upper limit thresholding, it is also possible to offline thresholding.For upper limit thresholding, when beyond report thresholding when report examining report.For offline thresholding, examining report is reported less than when reporting thresholding.In a word, as long as Testing index information does not meet the limitation for reporting thresholding, then examining report is reported.
For example, being upper limit thresholding when reporting thresholding, the Testing index information of user equipment detection reports thresholding beyond default, then it is assumed that now there is interference in the communication channel of access point apparatus to be detected；User equipment is in this, as detection judged result, and by this judged result reporting base station in the form of examining report.The cellular network still provided on the communication process for reporting examining report by base station is completed.
In addition, following content can be included in the blunt announcement of detection：
Location of user equipment, the positional information of user equipment can be absolute location information, such as is latitude and longitude information；Or relative position information, such as the position relative to cellular network；User can measure the signal of cellular network, and its relative position in cellular networks is determined by measuring cellular network signals.
Testing index and Testing index information；Explanation has been given among foregoing teachings on Testing index and Testing index information, narration is not repeated herein.
The information of access point apparatus to be detected, the information is consistent with the access-in point information to be detected included in detection instruction；Detection data for access point apparatus to be detected are reported in the lump included in the Testing index information.
The information of relation access point apparatus, by the foregoing description for reporting thresholding, it is known that reporting the limitation of thresholding when Testing index information is not met（Exceed or to reach thresholding）, then examining report is reported.And according to for calculating the measured data of Testing index information, specific be result in from which access point apparatus signal or data frame in the limitation that Testing index information is unsatisfactory for reporting thresholding, the present embodiment it is considered that the access point apparatus for the limitation for causing Testing index information to be unsatisfactory for thresholding has interference to access point apparatus to be detected can be learned.User equipment is according to Testing index information and default reports thresholding, it is determined that cause inspection After the access point apparatus for surveying the indication information limitation that is unsatisfactory for thresholding, as relation access point apparatus and the information of relation access point apparatus, such as title of relation access point apparatus and address are reported.Specific detection data for relation access point apparatus will be contained in and be reported in the lump in the actually detected value information.Base station can learn that the interference for having which access point apparatus to treat detection device near user equipment is stronger according to relation node device information in the present embodiment.
Actually detected value information；The actually detected value refers to that Testing index is carried out to detect obtained real data numerical value；The actual detection value information of surveying can include the measured value for access point apparatus Testing index to be detected, can also include the measured value for relation access point apparatus Testing index.
Free channel information, while reporting the information of the idle channel in the absence of interference, deposits in access point apparatus to be detected so as to base station and makes the adjustment such as follow-up channel change in case of interferers.
So far, user equipment side completes WLAN Interference Detection flow, is accurately obtained the disturbed condition of a certain specific location.The above-mentioned embodiment of the method for correspondence, the present invention is also corresponding to disclose a kind of Interference Detection system, and the Interference Detection system is typically disposed among user equipment, shown in reference picture 3, and the system architecture is as follows：Trigger module 301, the detection for receiving base station is instructed, and triggers Interference Detection.
In the present embodiment, user equipment is located at a certain ad-hoc location, and directly carries out Interference Detection using system described in the present embodiment at the position, so the testing result measured accurately illustrates disturbed condition actual at the position.
The base station is cellular network base station, and the cellular network namely refers to what operator at this stage provided
2G/ 3G/4G networks, such as GSM network or cdma network, or LTE network.Base station described in the present embodiment can be understood as base station or base station controller in the evolution base station in the base station of broad sense, such as LTE network, and 2G/ 3G/4G networks, in the present embodiment within the scope of the base station.Within the scope of the cellular network that one base station is provided, the access point apparatus that may be divided into comprising multiple operators, the Interference Detection for these access point apparatus is required to coordinate the base station to complete.Communication between the base station and user equipment is that the cellular network provided by base station is realized；During existing Interference Detection, related communication is completed using WLAN, and the defect for influenceing WLAN normally to use.Also the information of access point apparatus to be detected is just included in the detection instruction；To be detected connect can specifically be included Access point device name, access point apparatus ID to be detected or channel number to be detected etc..In general channel to be detected is exactly the channel that access point to be detected is used.If not comprising channel number to be detected, the numbering of user equipment channel according to used in access point apparatus ID voluntarily searches for the access point apparatus to be detected.Whether Testing index can also be set in detection instruction reports thresholding, be disturbed with the communication for defining access point apparatus to be detected.Thresholding is reported subsequently to will be explained on Testing index.
The core concept of the present embodiment is using user equipment to realize described Interference Detection process in itself；And the control action for user equipment is only played in base station in detection process in the present embodiment, and it is not involved in actual detection.So the trigger module 301 receives the detection instruction of base station, and then start follow-up testing process.
Detection module 302, for the Testing index in the communication channel according to detection command detection access point apparatus to be detected, obtains Testing index information.
After detection instruction is received, then testing process is started according to detection instruction.Specifically, detection module 302 searches channel to be detected, and the signal intelligence in channel to be detected is detected according to the access point apparatus information to be detected and channel information to be detected that are included in detection instruction.In addition, the interference in channel to be detected not only may be from channel to be detected in itself, it is also possible to come from adjacent channel.It is advantageous to, the also pair adjacent channel overlapping with channel frequency to be detected of detection module 302 is detected；To ensure the comprehensive and accuracy of Interference Detection.
It is specific for defining with the presence or absence of interference in detection process, will be according to Testing index information.For access point apparatus to be detected and channel to be detected, other near it of the search of detection module 302 measure in channel to be detected Testing index from access point apparatus to be detected and from there may be the Testing index of the access point apparatus of interference or channel there may be the access point apparatus of interference or channel；Testing index information is finally given, and judges whether these really generate interference there may be the access point apparatus of interference or channel to access point apparatus to be detected and channel to be detected.
In the present embodiment, the quantization parameter for weighing disturbed condition will be used as using Testing index；The index such as signal intensity rate or difference, signal quality ratio or difference, path loss or available frame count ratio is possibly as Testing index.
