Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The indoor distribution system is a construction means of coverage extension, is a scheme for improving a mobile communication environment in a building aiming at an indoor user group, and particularly, the indoor distribution system uniformly distributes signals of a mobile base station at each indoor corner by utilizing an indoor antenna distribution system so as to ensure that an indoor area has ideal signal coverage.
However, because a large number of antennas, passive devices, and the like are distributed under an indoor distribution system, and these antennas and devices all have the problem of missing effective monitoring means, that is, when a local area fails, a network management platform and a performance platform cannot find the failure in time, cannot rapidly eliminate network hidden dangers, and have a great influence on indoor network quality, thereby affecting user experience.
In addition, in the existing scheme, when a fault is usually processed, the site measurement is generally performed by using manpower and instruments to locate the position where the fault occurs, and in this way, for an area with a large coverage area of a cell divided into rooms, for example, a cell with a large number of floors or a large number of buildings, a large amount of manpower is required to perform troubleshooting, so that the fault location accuracy is low, and the location efficiency is low.
In view of this, the embodiment of the present application provides a method and an apparatus for locating a fault of an indoor sub-cell, where signal quality is analyzed by using location information of a resident user in the indoor sub-cell and signal parameter information reported by a terminal used by the resident user, so as to locate the fault of the indoor sub-cell, and manual measurement and location are not needed, thereby improving accuracy of fault location, and further improving user experience.
As shown in fig. 1, which is a flowchart of an indoor cell fault location method provided in an embodiment of the present application, an execution subject of the method shown in fig. 1 may be an indoor cell fault location device, and referring to fig. 1, the method includes:
s101: and acquiring the position information of the resident user in the indoor sub-cell.
Specifically, the location information of the user in the indoor cell may include: and resident building information, floor information and floor direction information of the user.
In addition, in the embodiment of the application, the resident user of the indoor sub-cell is selected as the sample, and the fault in the indoor sub-cell is positioned by using a large amount of sample data, so that the positioning accuracy can be improved.
It should be noted that the resident user in the embodiment of the present application includes a plurality of users, that is, at least one user.
S102: and acquiring signal parameter information reported by the terminal equipment used by the resident user.
In the embodiment of the application, the signal quality of the position where the resident user is located can be determined by acquiring the signal parameter information reported by the terminal equipment used by the resident user, so that whether a fault exists in the position where the resident user is located can be determined.
S103: and carrying out the indoor sub-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 Report (Measurement Report, MR coverage, MR average level, MR weak coverage sampling point number, MR sampling point, MR weak coverage sampling point ratio, 2G (second generation mobile communication system) fallback times, 3G (third generation mobile communication system) fallback times, Long Term Evolution (LTE) call completing rate, LTE call dropping rate, and LTE handover success rate.
In step S101, the location information of the resident user in the indoor sub-cell is acquired, and it is necessary to determine which users in the indoor sub-cell belong to the resident user before acquiring the location information.
In the embodiment of the application, before the position information of at least one resident user in the indoor sub-cell is obtained, the user whose staying time in the indoor sub-cell is longer than the preset time within the set time is identified as the resident user in the indoor sub-cell.
Specifically, the Identification of the resident user in the cell of the indoor sub-cell can be performed by extracting the relevant information such as the International mobile subscriber identity Number (IMSI), time, evolved base station cell identity (eNodeB cellidentity, ECI), and the like of the user, so as to obtain the data such as the IMSI, the ECI, the average residence time, the residence time, and the like of the resident user in the cell of the indoor sub-cell.
Generally, according to the geographic location of the cell and the living habits of most users, the places where the residence time of the users is long include the home and the work place, and the indoor sub-cell is usually the home place or the work place. Therefore, the resident user identification performed in the embodiment of the present application includes a resident user identification of a work place and a resident user identification of a home place.
As shown in fig. 2, for the resident subscriber identification of the work place, the resident subscriber identification of the work place is determined that the subscriber is a resident subscriber of the work place of the cell, according to the residence time of the subscriber in each cell during a recent period of time, for example, the last two weeks of work day time, if the average residence time of the subscriber in the cell per day exceeds a preset time.
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.
For the home location resident user identification, the user is determined to be a resident user at the home location of the cell if the average residence time per day of the user in the cell exceeds a preset time according to the residence time of the user in the cell in the latest period of time, for example, the residence time of the user in each cell in the morning of the latest two weeks.
It can be understood that, when the resident user at the home location identifies, the early morning time is selected for identification according to the living habits of the user, and the preset time duration may also be 2 hours, which is not limited in the embodiment of the present application.
In a possible implementation manner, the present application may refer to the method shown in fig. 3 to obtain the location information of the resident user in the indoor sub-cell, and as shown in fig. 3, a flowchart of a method for obtaining the location information of the resident user in the indoor sub-cell provided by the present application may include:
s1011: building information and floor information of a part of resident users are determined by using an OTT (over the top) positioning technology and a WIFI (wireless fidelity) 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 direction information of the part of resident users according to configuration parameter information in the neighbor cell information.
S1013: and acquiring the characteristic parameter information of a part of resident users, performing feature clustering according to the characteristic parameter information of a part of resident users, and determining the position information of another part of resident users.
It should be noted that, steps S1011, S1012 and S1013 in the method shown in fig. 3 are not in a fixed order, and S1013 may be executed first, and then S1011 and S1012 are executed, which is not limited in the embodiment of the present application.
The steps involved in fig. 3 above will be described in detail below with reference to the other figures.
In step S1011, The Over-The-Top (OTT) positioning technology refers to a service provided to a mass user by relying on internet Application, acquires location information of The user based on Application (APP) software, extracts latitude and longitude information of The location service user through data analysis in an LTE network S1-U interface, associates The user identifier with MR data at that moment, and implements accurate indoor and outdoor MR data distinguishing and positioning 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 APPs for positioning location information on the terminal device, and the location information of the user can be acquired by using the OTT technology. For example, when the user opens the beauty group takeout on the mobile phone, the OTT positioning technology can be used to obtain the location information of the user.
Furthermore, the WIFI layering technology is used for positioning a building where a user is located by mining longitude and latitude information of the user, and carrying out WIFI layering by utilizing a plurality of WIFI network information collected by the same building, so that the building, the floor and the WIFI information of the resident user are obtained.
After the user is connected to WIFI, the positioning of the building floor of the user can be achieved.
As shown in fig. 4, a schematic diagram of building floor location provided in this embodiment of the present application is provided, specifically, a user may collect, at a same location Point, a Media Access Control (MAC) value and a Received Signal Strength Indication (RSSI) value of multiple Wireless Access Points (APs) of the building.
It should be noted that the RSSI ranging can use the formula in the prior art, and will not be described in detail herein.
The building floor information of the user is determined, and the floor direction 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 diagram of the floor direction shown in fig. 5, the resident user positioned on the building floor is associated with the neighboring cell information thereof, and is combined with the configuration information of other outdoor base stations in the neighboring cell to position the floor direction of the user.
For example, the nearest neighbor cell to the serving cell can be determined by the working parameters (latitude and longitude information) in the configuration information, so as to determine the floor direction where the resident user is located.
Since the OTT positioning technology is used for positioning the position information of the user 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 the resident users who are not located by the OTT location and WIFI layering technology, the characteristic parameter information of the resident users who have located the position information can be obtained, feature clustering is carried out according to the characteristic parameter information of one part of the resident users, and the position information of the other part of the resident users is determined.
It should be noted that, in the embodiment of the present application, the positioning using OTT positioning and WIFI layering technology may be understood as "building stereo 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 the resident users are located, quality information of the serving cell, neighboring cell field intensity characteristic information of the serving cell in which a part of the resident users are located, and neighboring cell quality.
It is to be understood that the characteristic parameter information is not limited to the above-described parameters.
In the embodiment of the present application, the method shown in fig. 6 may be used to determine location information of another part of resident users, as shown in fig. 6, the method includes:
s201: and acquiring the characteristic parameter information of another part of resident users.
S202: and determining the distance similarity between one part of the resident user and the other part of the resident user according to the characteristic parameter information of one part of the resident user and the characteristic parameter information of the other part of the resident user.
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 present application, the distance similarity between one part of the resident users and another part of the resident users may be calculated and determined in a manner of similarity measurement between sample data of the resident users.
Assume resident user data set X ═ XmSample properties in X describe the attributes a with d number of description attributes 1,2, …, total1,A2,…,AdAnd d description attributes are all continuous type attributes. Data sample xi＝(xi1,xi2,…,xid),xj＝(xj1,xj2,…,xjd) Wherein x isi1,xi2,…,xidAnd xj1,xj2,…,xjdAre respectively a sample xiAnd xjCorresponding to d description attributes A1,A2,…,AdThe specific value of (a).
It is to be understood that the d description attributes refer to the above-mentioned characteristic parameter information.
Sample xiAnd xjThe similarity between them is usually determined by the distance d (x) between themi,xj) Expressed, the formula is as follows:
from the above equation, one can derive: the smaller the distance, the sample xiAnd xjThe more similar, the smaller the degree of difference; the greater the distance, sample xiAnd xjThe more dissimilar, the greater the degree of difference.
By calculating the distance similarity between the sample data of the undetermined resident user and the positioned resident user, the undetermined resident users with the similarity meeting the preset condition can be classified into the positioned group.
In the embodiment of the application, the resident users who do not perform building three-dimensional positioning are identified and classified in a characteristic clustering mode, so that the sample size is increased, and the positioning precision is improved.
It is understood that resident users with a degree of similarity within a certain range can be categorized into a group of located resident users.
In the embodiment of the present application, the resident users may be grouped into a set according to the following format: building-floor-orientation-user group.
Further, in the embodiment of the present application, the following method may be adopted to perform the indoor partition cell 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:
specifically, the fault type of the indoor sub-cell is located 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 failure types of the cell may include: the fault of the whole building, the fault of the local building and the fault of the combiner or the reverse connection.
As described above, the signal parameter information reported by the resident user on the terminal device is acquired, and the fault type of the indoor sub-cell is represented by the acquired change rule of the signal parameter information.
It should be noted that the signal parameter information reported by the resident user on the terminal device is not limited to the above described parameter information, for example, the parameter information such as the number of mobile MR sampling points, the average level of the mobile MR, the coverage rate of the mobile MR, the number of connected MR sampling points, the average level of connected MR, the coverage rate of connected MR, the number of telecommunication MR sampling points, the average level of telecommunication MR, the coverage rate of telecommunication MR, etc. may also be reported, and by reporting the signal parameter information of different operators, the comparison adjustment may be performed, the network quality of the resident user may be optimized, so as to improve the user experience.
Specifically, for the fault of the whole building, the change rule of the signal parameter information is as follows:
1) the historical data of the building shows that each floor occupies a room sub-cell, which indicates that the building has room sub-coverage, but the current user group cell data occupies more macro-station sampling points.
2) The sampling point change proportion of the building user group main service community is 80 percent; or (the current indoor cell sampling point ratio-the historical indoor cell sampling point ratio)/the historical indoor cell sampling point ratio < -80%, are both considered adjustable.
3) When the traffic of a Global System for Mobile communication (GSM) cell without co-coverage or a GSM cell with co-coverage drops by more than 50%, the traffic is considered adjustable.
4) A room cell is considered adjustable 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 local building faults, the change rule of the signal parameter information is as follows:
1) more than 80% of the floors of the building with historical data occupy the indoor sub-cells and are considered adjustable.
2) The sampling point change proportion of the building user group main service cell is less than 80%, and the sampling point is considered to be adjustable.
3) The MR weak coverage of the user group per position of the room cells in the partial floors rises by 15% or the data traffic drops by 15%, considered adjustable.
The method can locate the local area of the indoor sub-cell to have faults, and the prior art can only locate the local area but not locate the local area at the cell level.
For the combiner fault or the reverse connection, the change rule of the signal parameter information is as follows:
1) different user groups of the building can occupy 2/3G cells and 4G (fourth generation wireless communication technology) cells of indoor partitions, but the 4G cells occupy the time length proportion far less than 2G cells, and the proportion is considered to be adjustable.
2) The flow of 4G indoor sub-cells occupied by user groups in the building is less than 100M, and the flow is considered to be adjustable.
The flow of 2G indoor sub-cells occupied by user groups in the building is more than 50M and is considered adjustable.
In the embodiment of the application, the fault can be directly analyzed and positioned at the background by the fault method, personnel do not need to be arranged for field test positioning, the labor cost expenditure of a company is greatly saved, and the working efficiency is improved.
Through the above detailed description of the embodiment of the method, the method for locating a cell partition fault may specifically include a flowchart shown in fig. 7, and specifically, may include:
s301: identifying a resident user; s302: resident user building three-dimensional positioning; s303: clustering resident user characteristics; s304: counting the resident user group indexes; s305: and identifying the compartment fault.
It should be noted that, in the specific implementation of the steps related to fig. 7, the steps S302 and S303 may be permuted, and there is no necessary sequence between the steps, that is, some of the resident users may be clustered first, and then other resident users may be positioned stereoscopically.
The terms "part" and "another part" are used herein only for distinguishing the resident users and not for distinguishing the order, and those skilled in the art should understand the meaning.
It can be understood that the resident user group index statistics is to obtain the signal parameter information of the resident user, the indoor partition fault identification is to perform fault location on the indoor partition cell, and the location includes location, which can be understood as identification of fault type.
Based on the same concept as the embodiment of the indoor sub-cell fault positioning method, the embodiment of the invention also provides an indoor sub-cell fault positioning device. Fig. 8 is a structural block diagram illustrating a cell location method according to an embodiment of the present application, where the cell location method includes: acquisition unit 101, processing unit 102.
The acquiring unit 101 is configured to acquire location information of at least one resident user in a residential cell and signal parameter information reported by a terminal device used by the resident user.
