The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The indoor distribution system is a construction means for coverage extension, is a scheme for improving mobile communication environment in a building aiming at indoor user groups, and particularly utilizes an indoor antenna distribution system to uniformly distribute signals of a mobile base station at each corner in a room, so that an indoor area is ensured to have ideal signal coverage.
However, since a large number of antennas, passive devices and the like are distributed under the indoor distribution system, the antennas and the devices have the problem of missing effective monitoring means, namely, when a local area fails, the network management platform and the performance platform cannot discover the failure in time, cannot quickly eliminate network hidden trouble, and has great influence on the indoor network quality, thereby influencing the user experience.
In addition, in the existing scheme, generally, when the faults are processed, field measurement is carried out by using manpower and instruments so as to position the fault, and in the mode, for the areas with larger coverage areas of the indoor cells, such as the cells with more floors or more buildings, a large amount of manpower is required for checking, so that the fault positioning accuracy is lower and the positioning efficiency is lower.
In view of the above, embodiments of the present application provide a method and an apparatus for positioning a fault in a cell, which analyze signal quality by using location information of a resident user in the cell and signal parameter information reported by a terminal used by the resident user, so as to position the fault in the cell without manual measurement and positioning, thereby improving accuracy of fault positioning and further improving user experience.
As shown in fig. 1, which is a flowchart of a method for positioning a cell failure in a cell, the execution body of the method shown in fig. 1 may be a device for positioning a cell failure, and referring to fig. 1, the method includes:
s101: and acquiring the position information of the resident user in the indoor cell.
Specifically, the location information of the user in the cell may include: building information, floor information, and floor azimuth information where the resident user is located.
In addition, in the embodiment of the application, the resident user of the cell is selected as a sample, and a large amount of sample data is utilized to locate faults in the cell, so that the locating accuracy can be improved.
It should be noted that, in the embodiment of the present application, the resident user includes a plurality of users, that is, at least one user.
S102: and acquiring signal parameter information reported by terminal equipment used by a resident user.
In the embodiment of the application, the signal quality of the position of the resident user can be determined by acquiring the signal parameter information reported by the terminal equipment used by the resident user, so that whether the position of the resident user has a fault or not can be judged.
S103: and carrying out cell fault positioning according to the signal parameter information reported by the terminal equipment used by the resident user and the position information of the resident user.
Specifically, the signal parameter information in the embodiment of the present application may include at least one of the following parameters: measurement reports (Measurement Report, MR coverage rate, MR average level, MR weak coverage sampling point, MR weak coverage sampling point duty ratio, number of 2G (second generation mobile communication system) fallbacks, number of 3G (third generation mobile communication system) fallbacks, long term evolution (Long Term Evolution, LTE) call completing rate, LTE call dropping rate, and LTE handover success rate.
Acquired in step S101 is the location information of the resident users within the cell, it is then necessary to determine which users within the cell belong to the resident users before acquiring the location information.
In the embodiment of the application, before the position information of at least one resident user in the indoor partition cell is obtained, the user with the stay time length longer than the preset time length in the indoor partition cell within the set time length can be identified as the resident user in the indoor partition cell.
Specifically, the identification of the resident user of the cell can be performed by extracting relevant information such as the international mobile subscriber identification number (International Mobile Subscriber Identification Number, IMSI), time, evolved node B cell identifier (eNodeB Cell Identifier, ECI) and the like of the user, so as to obtain data such as the IMSI, ECI, average residence time, residence time period and the like of the resident user in the cell.
Typically, sites where the user resides for a longer period of time include home and work sites, and the cell division cells are typically home sites or work sites, depending on factors such as the geographic location of the cell and the lifestyle habits of most users. Thus, in embodiments of the present application, resident user identification includes both resident user identification of a work site and resident user identification of a home site.
As shown in fig. 2, a schematic diagram of resident user identification provided in an embodiment of the present application is provided, for resident user identification of a workplace, the resident time of a user in each cell may be according to the last period of time, for example, the last two weeks of working day time, and if the average resident time of the user in the cell exceeds a preset time, it may be determined that the user is the resident user of the workplace of the cell.
It is understood that the working day refers to monday through friday, and the preset time period may be set to 2 hours, for example, which is not limited in the embodiment of the present application.
The home location resident user identification is based on the resident time of the user in each cell in the last period of time, for example, in the morning of the last two weeks, and if the average resident time of the user in the cell per day exceeds the preset time, the user can be determined to be the home location resident user in the cell.
It can be understood that when the resident user at the home location is identified, the user selects the early morning time for identification according to the living habit of the user, and the preset time length can be 2 hours, which is not limited by the embodiment of the application.
In a possible implementation manner, the embodiment of the present application may refer to a method shown in fig. 3 to obtain location information of a resident user in a cell, and as shown in fig. 3, a flowchart of a method for obtaining location information of a resident user in a cell according to an embodiment of the present application may include:
s1011: and determining building information and floor information of a part of resident users by using an OTT (on-the-fly) positioning technology and a WIFI layering technology which are provided based on the Internet.
S1012: and acquiring neighbor cell information of a service cell where a part of resident users are located, and determining floor azimuth information of a part of resident users according to configuration parameter information in the neighbor cell information.
S1013: and acquiring characteristic parameter information of a part of resident users, performing characteristic clustering according to the characteristic parameter information of the part of resident users, and determining the position information of the other part of resident users.
It should be noted that, steps S1011, S1012 and S1013 involved in the method shown in fig. 3 are not in a fixed sequence, and S1013 may be performed first and then S1011 and S1012, which is not limited in the embodiment of the present application.
The steps involved in fig. 3 described above will be described in detail with reference to other drawings.
In step S1011, the internet television (Over-The-Top) positioning technology refers to services provided to a large number of users by internet Application, obtains location information of The users based on Application (APP) software, extracts longitude and latitude information of The location service users through data analysis in an LTE network S1-U interface, correlates with MR data at The moment by using a user identifier, and realizes accurate indoor and outdoor segmentation and positioning of The MR data by using a specific algorithm.
In the embodiment of the application, the longitude and latitude information of the user is positioned by using the OTT positioning technology, so that the accuracy of fault positioning can be improved.
Specifically, the user uses some APP used for positioning the position information on the terminal device, and the position information of the user can be obtained by using OTT technology. For example, the user opens the beauty take-out on the mobile phone, and at this time, the OTT positioning technology is utilized to obtain the position information of the user.
Furthermore, the WIFI layering technology is used for positioning the building where the user is located by excavating longitude and latitude information of the user, and performing WIFI layering by utilizing a plurality of pieces of WIFI network information acquired by the same building, so that building, floor and WIFI information of the resident user are obtained.
After the user is connected to the WIFI, positioning of the building floors of the user can be achieved.
As shown in fig. 4, a schematic diagram of building floor positioning is provided in an embodiment of the present application, specifically, a user may collect local area networks (Media Access Control, MAC) and received signal strength indication (Received Signal Strength Indication, RSSI) values of a plurality of wireless access points (Wireless Access Point, AP) of the building at the same location point.
It should be noted that, the RSSI ranging may use a formula in the prior art, and will not be described in detail herein.
Building floor information of the user is determined, and floor azimuth information of the user is also required to be determined so as to determine the specific position of the user.
Specifically, referring to the positioning schematic diagram of the floor azimuth shown in fig. 5, the resident user positioned to the floor of the building locates the floor azimuth of the user by associating with the neighbor information of the resident user and combining with the configuration information of other outdoor base stations in the neighbor.
For example, the nearest neighbor to the serving cell may be determined by a parameter (latitude and longitude information) in the configuration information, so as to determine the floor azimuth where the resident user is located.
Because the OTT positioning technology can position the position information of the user only after the user opens the APP on the terminal, only a part of the position information of the resident user can be positioned by using the OTT positioning technology and the WIFI layering technology.
For resident users which are not positioned by using OTT positioning and WIFI layering technology, the embodiment of the application can acquire the characteristic parameter information of the resident users which are positioned to the position information, and perform characteristic clustering according to the characteristic parameter information of one part of resident users to determine the position information of the other part of resident users.
It should be noted that, in the embodiment of the present application, positioning by using OTT positioning and WIFI layering technologies may be understood as "building stereotactic positioning".
Specifically, the characteristic parameter information may include: at least one of field intensity characteristic information of a serving cell in which a part of resident users are located, quality information of the serving cell, neighbor field intensity characteristic information of a serving cell in which a part of resident users are located, and neighbor quality.
It is to be understood that the characteristic parameter information is not limited to the above parameters.
In an embodiment of the present application, referring to the method shown in fig. 6, location information of another part of resident users may be determined, as shown in fig. 6, where the method includes:
s201: and acquiring characteristic parameter information of another part of resident users.
S202: and determining the distance similarity between the part of resident users and the other part of resident users according to the characteristic parameter information of the part of resident users and the characteristic parameter information of the other part of resident users.
S203: and determining the position information of the other part of resident users with the distance similarity meeting the preset condition as the position information of the other part of resident users.
Specifically, in the embodiment of the application, the distance similarity between one part of resident users and the other part of resident users can be calculated and determined by adopting a similarity measurement mode between resident user sample data.
Let resident user data set x= { X m M=1, 2, …, total }, sample properties in X describe properties a with d 1 ,A 2 ,…,A d Is represented, and d description attributes are all continuous attributes. Data sample x i ＝(x i1 ,x i2 ,…,x id ),x j ＝(x j1 ,x j2 ,…,x jd ) Wherein x is i1 ,x i2 ,…,x id And x j1 ,x j2 ,…,x jd Respectively sample x i And x j Corresponding to d description attributes A 1 ,A 2 ,…,A d Specific values of (2).
It is understood that d description attributes refer to the above-mentioned characteristic parameter information.
Sample x i And x j The similarity between them is usually determined by the distance d (x i ,x j ) Expressed, the formula is as follows:from the above formulaAnd (3) out: the smaller the distance, sample x i And x j The more similar, the smaller the degree of difference; the greater the distance, sample x i And x j The less similar, the greater the degree of difference.
By calculating the distance similarity between the sample data of the non-located resident users and the located resident users, the non-located resident users with the similarity meeting the preset condition can be classified into the located group.
In the embodiment of the application, the resident users which are not subjected to building three-dimensional positioning are identified and classified in a characteristic clustering mode, so that the sample size is increased, and the positioning accuracy is improved.
It will be appreciated that resident users having a similarity within a certain range may be categorized into the group of resident users that have been located.
In the embodiment of the application, the resident users can be assembled into a set according to the following format: building-floor-azimuth-user group.
Furthermore, in the embodiment of the application, the fault location of the cell can be performed according to the signal parameter information reported by the terminal equipment used by the resident user and the position information of the resident user in the following manner:
specifically, according to the position information reported by the terminal equipment used by the resident user and the change rule of the signal parameter information of the resident user, the fault type of the indoor partition cell is positioned.
The types of failures of the cell may include: a whole building failure, a local building failure, a combiner failure, or a reverse connection.
As described above, signal parameter information reported by the resident user on the terminal device is obtained, and the fault type of the indoor cell is represented by the obtained change rule of the signal parameter information.
It should be noted that, the signal parameter information reported by the resident user at the terminal device is not limited to the above-described parameter information, for example, parameter information such as mobile MR sampling point number, mobile MR average level, mobile MR coverage rate, connected MR sampling point number, connected MR average level, connected MR coverage rate, telecommunication MR sampling point number, telecommunication MR average level, telecommunication MR coverage rate and the like may also be reported, and by reporting signal parameter information of different operators, comparison adjustment may be performed, and network quality of the resident user may be optimized so as to improve user experience.
Specifically, for a whole building fault, the change rule of the signal parameter information is as follows:
1) The historical data of the building shows that each floor occupies a cell with a cell, which indicates that the building has a cell coverage, but the data of the current user group cell occupies more sampling points of a macro station.
2) Building user group main service cell sampling point change ratio > =80%; or (current indoor cell sampling point duty ratio-historical indoor cell sampling point duty ratio)/historical indoor cell sampling point duty ratio < = -80%, are all considered to be adjustable.
3) A global system for mobile communications (Global System for Mobile communication, GSM) cell without co-coverage or a co-coverage GSM cell is considered tunable when the flow rate drops by more than 50%.
4) The cell is considered to be tunable when the MR weak coverage of the user group in all floors rises by 15% or the MR average signal level decreases by more than 15dB or the data traffic decreases by 15%.
For a local building fault, the change rule of the signal parameter information is as follows:
1) More than 80% of the historical data of the building occupy the room to divide cells, and the historical data is considered to be adjustable.
2) The sampling point change ratio of the main service cell of the building user group is less than 80 percent, and the building user group is considered to be adjustable.
3) The MR weak coverage of the user group of the cell at each location in the partial floor is increased by 15% or the data traffic is reduced by 15%, which is considered to be adjustable.
The method can locate the local area of the cell of the room partition to fail, but the prior art can only locate the cell level and can not locate the local area.
For a combiner fault or reverse connection, the change rule of the signal parameter information is as follows:
1) Different user groups in the building can occupy 2/3G cells and 4G (fourth generation wireless communication technology) cells of the room, but the 4G cells occupy a much smaller proportion of time than the 2G cells, and the proportion is considered to be adjustable.
2) The 4G room cell flow occupied by the user group in the building is less than 100M, and the user group is considered to be adjustable.
The 2G room cell flow occupied by the user group in the building is more than 50M, and the user group is considered to be adjustable.
In the embodiment of the application, the fault can be directly analyzed and positioned in the background by the fault method, and the personnel are not required to be arranged for field test positioning, so that the labor cost of a company is greatly saved, and the working efficiency is improved.
As described in detail above for this embodiment of the method, the method for positioning a cell failure in a cell may specifically include a flowchart as shown in fig. 7, and specifically may include:
s301: resident user identification; s302: building three-dimensional positioning of resident users; s303: clustering resident user features; s304: counting resident user group indexes; s305: and (5) identifying room faults.
It should be noted that, for the steps related to fig. 7, in the specific implementation, the steps S302 and S303 may be changed in order, and there is no necessary order between them, that is, some of the resident users may be clustered first, and then building stereotaxic is performed for other resident users.
Where "a portion" is to be distinguished from "another portion" only for the purpose of distinguishing between resident users and not as a sequential order, the meaning will be understood by those skilled in the art.
It can be understood that the resident user group index statistics is to obtain signal parameter information of resident users, and the indoor division fault identification is to perform fault location on indoor division cells, where the location includes location of a position, and can be understood as identification of fault types.
Based on the same conception as the embodiment of the method for positioning the faults of the indoor subareas, the embodiment of the application also provides a device for positioning the faults of the indoor subareas. Fig. 8 is a block diagram of a cell failure location structure according to an embodiment of the present application, including: an acquisition unit 101, a processing unit 102.
The acquiring unit 101 is configured to acquire location information of at least one resident user in the indoor partition cell and signal parameter information reported by a terminal device used by the resident user.
The location information includes building information, floor information, and floor azimuth information where the resident user is located.
And the processing unit 102 is configured to perform cell division fault location according to the signal parameter information reported by the terminal device used by the resident user and the location information of the resident user, which are acquired by the acquiring unit 101.
Specifically, the signal parameter information includes at least one of the following parameters: the method comprises the steps of measuring report MR coverage rate, MR average level, MR weak coverage sampling point number, MR sampling point, MR weak coverage sampling point duty ratio, 2G fallback times, 3G fallback times, long term evolution LTE call completing rate, LTE call completing rate and LTE switching success rate.
Optionally, the apparatus further comprises: the identifying unit is used for identifying that the user with the stay time longer than the preset time length in the indoor cell is the resident user in the indoor cell in the set time length.
