The indoor distribution system fault monitoring method based on MDT data can be applied to an application environment shown in fig. 1. Wherein the terminal 102 communicates with the server 104 via a network. The server 104 may acquire the room-division user identifier in the MDT data to further acquire the MDT data corresponding to the room-division user identifier in the total MDT data, and screen out the room-division MDT data corresponding to the room-division fixed user identifier in the total MDT data according to the MDT data corresponding to the room-division user identifier, so as to acquire the historical room-division MDT data corresponding to the room-division fixed user identifier, compare the historical room-division MDT data with the room-division MDT data, and finally determine a fault probability value of the indoor distribution system according to a classification comparison result of the historical room-division MDT data and the room-division MDT data. The terminal 102 may be, but not limited to, various personal computers, notebook computers, smartphones, tablet computers, and portable wearable devices, and the server 104 may be implemented by a stand-alone server or a server cluster composed of a plurality of servers.

In one embodiment, as shown in fig. 2, there is provided an indoor distributed system fault monitoring method based on MDT data, which is illustrated by taking the application of the method to the server 104 in fig. 1 as an example, and includes the following steps:

step 202, acquiring a room division user identifier in MDT data; and the indoor user identification is determined according to the cell identification in the MDT data.

The MDT (Minimization of Drive-tests, minimization of drive tests) is an automatic drive test technology introduced in the 3gpp r10 stage, and the technology mainly carries user information and accurate longitude and latitude data information in a measurement report, so that the application value of the technology for evaluating network coverage based on users and positions is high.

The indoor user identification refers to a user identification with a global unique field in MDT data, and the indoor user identification can be defined to comprise 'MME Group ID, MME Code, MME UE S1AP ID and IMSI'; "MME" (Mobility Management Entity) is the mobility management node of the TLE network, responsible for the part of the signaling process; "MME Group ID" means MME Group identity, unique in one PLAN; "MME Code" means MME number, unique in one MME Group; "MME UE S1AP ID" means the unique identity of the UE (user terminal) on the MME side S1 interface; "IMSI" (International Mobile Subscriber Identity) represents an international mobile subscriber identity. It should be noted that, because the IMSI field is empty after the MDT data is desensitized with respect to the user privacy data, the present application proposes to use "MME Group id+mme code+mme UE S1AP ID" as the indoor user identifier with global uniqueness in a certain time interval (e.g. 1 to 3 hours).

Specifically, the MDT data includes not only information such as a time identifier (timestamp), a user identifier, a cell identifier, an RSRP (Reference Signal Receiving Power, reference signal received power), and the like, but also service cell measurement information, neighbor cell measurement information, and the like, and various information can be used as a primary key by using the user identifier to form an MDT sampling point data. Before obtaining the indoor user identifier, the server 104 needs to obtain MDT data first, and because the MDT data includes a plurality of pieces of sampling point data, and each piece of sampling point data includes information such as a cell identifier and a time identifier corresponding to the user identifier as a primary key, considering whether the indoor distribution system has a fault to be monitored, the MDT data needs to be screened out of sampling point data with a primary service cell type of "indoor" (the cell type includes "indoor" and "outdoor"), that is, the sampling point data with a cell type belonging to "outdoor" is screened out, so that the user identifier, that is, the indoor user identifier in the remaining sampling point data can be obtained.

And 204, obtaining MDT data corresponding to the indoor division user identification in the total MDT data, and screening out indoor division MDT data corresponding to the indoor division fixed user identification in the total MDT data according to the MDT data corresponding to the indoor division user identification.

The total amount of MDT data may be MDT sampling data under wider conditions set in terms of sampling time, sampling range, and the like, with respect to the MDT data.

Specifically, after screening and acquiring the indoor division user identifiers in the MDT data, the server 104 may extract, in time sequence, MDT sampling data corresponding to each indoor division user identifier, that is, MDT data corresponding to the indoor division user identifier, from the total MDT data, and then associate a base station basic information table and a base station cell neighbor table, analyze behavior characteristics of each user under the indoor distributed system site, that is, according to the MDT data corresponding to each indoor division user identifier, first screening out an indoor division fixed user identifier in the total MDT data, and further extract indoor division MDT data corresponding to each indoor division fixed user identifier.

And 206, acquiring historical room-division MDT data corresponding to the room-division fixed user identification, and comparing the historical room-division MDT data with the room-division MDT data.

The historical indoor distribution system MDT data refers to indoor distribution system MDT data correspondingly recorded by each indoor distribution system in a preset historical time period (for example, the historical period of the same acquisition period as the MDT data).

Specifically, after obtaining the historical room-score MDT data corresponding to each room-score fixed user identifier, the server 104 may establish a historical statistical model by using the historical room-score MDT data as a model sample, so as to use the historical statistical model to input the room-score MDT data, compare the room-score MDT data with the historical room-score MDT data, and finally output a classification comparison result.

More specifically, the historical statistical model is built by sampling data of a historical time period, but the historical time period needs to be close to the current sampling time and has enough quantity, so that MDT data corresponding to room division user identifiers with 3 historical same phases from the current sampling time can be obtained as historical room division MDT data.

For example, if the sampling time of the MDT data obtained in step 202 is "10" on monday: 00-11:00 "period, the historical time period may be the current monday period" 10:00-11: the first three monday periods of 00", that is, the sampling time of the MDT data, the total MDT data, and the historical chamber fraction MDT data may all be the sampling data of the same time interval.

Step 208, determining a fault probability value of the indoor distribution system according to the classification comparison result of the historical indoor distribution MDT data and the indoor distribution MDT data; and the fault probability value is used for prompting that the indoor distribution system has faults.

The historical indoor distribution MDT data comprises a historical average fixed user number, a historical fixed user sampling point number, a historical user occupation proportion, a historical average coverage level, a historical average coverage quality and historical traffic (historical uplink traffic and historical downlink traffic).

Specifically, the historical indoor distribution MDT data and the indoor distribution MDT data are subjected to classification comparison, after classification comparison results are obtained, the duty ratio of each classification comparison result in preset weights can be counted, so that the fault probability value of the indoor distribution system is determined, when the fault probability value reaches a preset fault prompt threshold, the fault probability value indicates that a fault exists in a passive device in the indoor distribution system which is analyzed currently, the server 104 can further generate a system fault prompt and send the system fault prompt to the terminal 102, and after the terminal 102 receives the system fault prompt, workers are prompted to process the fault in time.

According to the indoor distribution system fault monitoring method based on the MDT data, the indoor distribution user identification in the MDT data is obtained, the indoor distribution user identification is utilized to obtain the MDT data corresponding to the indoor distribution user identification in the total MDT data, the indoor distribution MDT data corresponding to the indoor distribution fixed user identification in the total MDT data is screened out according to the MDT data corresponding to the indoor distribution user identification, the historical indoor distribution MDT data corresponding to the indoor distribution fixed user identification is obtained, the historical indoor distribution MDT data is compared with the indoor distribution MDT data, so that the fault probability value of the indoor distribution system is determined according to the classification comparison result, and finally the indoor distribution system is prompted to have faults. By adopting the method, whether the passive devices in the indoor distribution system are faulty or not can be effectively monitored, and the accuracy of fault monitoring of the indoor distribution system is improved.

In one embodiment, as shown in FIG. 3, step 202 includes:

step 302, obtaining MDT data in a preset period;

step 304, extracting cell division cell MDT data in the MDT data according to the cell identification in the MDT data;

step 306, determining the user identification in the cell MDT data as the cell user identification.

Wherein, the MDT data within the preset period may refer to monday "10:00-11: the MDT data collected during the 00 "period, it is understood that in other embodiments, the MDT data during other predetermined periods may be used.

Specifically, the server 104 may acquire the indoor division user identifier in the MDT data, which may be the manner of acquiring the MDT data in the preset period, and because the MDT data includes a plurality of user identifiers and corresponding cell identifiers thereof, and the cell types of different cell identifiers are different, the indoor division cell MDT data in the MDT data may be extracted by screening the cell identifiers, that is, after the cell types of each cell identifier are determined by matching the MDT data with a pre-stored base station basic information table, the cell type is screened out as the "indoor" cell identifier, and then the corresponding MDT data is the indoor division cell MDT data, and the user identifier of the indoor division cell MDT data is the indoor division user identifier.

More specifically, since the MDT data may have a situation that the user identifier is repeated, after the MDT data of the indoor partition cell is obtained, the repeated user identifier in the MDT data of the indoor partition cell may be subjected to the deduplication processing, so that the different indoor partition user identifiers may be obtained.

In one embodiment, as shown in FIG. 4, step 304 includes:

step 402, obtaining a base station basic information table; the base station basic information table comprises a plurality of base station cell identifications; the plurality of base station cell identifiers respectively have corresponding cell types;

step 404, the cell identifier in the MDT data is matched with the cell identifiers of the plurality of base stations, and the target base station cell identifier is determined; the target base station cell identifier is a base station cell identifier matched with the cell identifier;

and step 406, if the cell type corresponding to the target base station cell identifier is an indoor cell type, extracting MDT data of the cell identifier matched with the target base station cell identifier from the MDT data, and taking the MDT data as the indoor cell MDT data.

The base station basic information table comprises a plurality of base station cell identifications, each base station cell identification is provided with a corresponding cell type, the base station basic information table is pre-stored in a database or obtained from other servers, and the base station basic information table can be used for identifying the type of each cell identification in the MDT data obtained at present.

Specifically, since the cell types to which the cell identifier belongs include "indoor" and "outdoor", after obtaining the MDT data in the preset period, the cell identifier needs to be matched with a plurality of base station cell identifiers included in the base station basic information table, and the cell type to which the cell identifier corresponds can be determined by obtaining the target base station cell identifier matched with the cell identifier in the base station basic information table, that is, when the cell type to which the target base station cell identifier corresponds is the indoor cell type, the cell type to which the cell identifier corresponds to be matched is determined to be "indoor", and the MDT data corresponding to the cell identifier is screened out, so that the cell division cell MDT data can be obtained.

In one embodiment, as shown in FIG. 5, step 204 includes:

step 502, obtaining the total MDT data in a preset period;

step 504, extracting the MDT data corresponding to the indoor user identifier from the total MDT data according to a time sequence, and taking the MDT data as indoor user MDT data;

step 506, according to the cell identifier corresponding to the indoor division user identifier, indoor division fixed user MDT data in the indoor division user MDT data are screened out;

and step 508, extracting the MDT data of the indoor fixed user, wherein the cell type corresponding to the cell identifier is the MDT data of the indoor cell type, and the MDT data is used as the indoor MDT data corresponding to the indoor fixed user identifier.

Specifically, after the server 104 screens the room user identifiers in the MDT data, the room user identifiers may be further used to screen the room user MDT data corresponding to the room user identifiers in the total MDT data, where the screening manner may be to extract the room user MDT data corresponding to the room user identifiers one by one in a time sequence by using the room user identifiers as primary keys, so as to obtain room user MDT data corresponding to the room user identifiers, and further analyze the cell identifiers corresponding to the room user identifiers in the room user MDT data, for example, the number of the cell identifiers and/or the information such as the adjacent relation and the distance between the cells corresponding to the cell identifiers, so as to screen the room fixed user MDT data in the room user MDT data.

At this time, the user identification included in the compartment fixed user MDT data is not an accurate compartment fixed user identification because: since there is a high probability that there is also non-cell MDT sampling data corresponding to the cell id among the cell-specific MDT data, that is, the cell-specific MDT data acquired by the server 104 may include MDT data sampled when the cell id is not the cell-specific MDT data, although the cell-specific MDT data is the MDT data corresponding to the cell id. Therefore, after obtaining the MDT data of the indoor fixed user, in order to further determine the indoor MDT data corresponding to each indoor fixed user identifier, it is also necessary to analyze the cell identifier in the indoor MDT data, and screen out the MDT data of which the cell type to which the cell identifier belongs is "indoor cell type", that is, screen out the MDT data of which the cell identifier in the indoor fixed user MDT data belongs to which the cell type is "outdoor cell type", where the remaining MDT data is the indoor MDT data corresponding to the indoor fixed user identifier.

In one embodiment, as shown in FIG. 6, step 506 includes:

step 602, performing deduplication processing on the cell identifier corresponding to the indoor user identifier;

step 604, a base station basic information table and a base station cell neighbor table are obtained, and the base station basic information table and the base station cell neighbor table are respectively subjected to association analysis processing with cell identifiers corresponding to the room division user identifiers after duplication removal, and room division fixed user MDT data in the room division user MDT data are screened out.

Specifically, after obtaining the indoor unit MDT data of the indoor unit user identifier, the server 104 may perform deduplication processing on the cell identifier corresponding to each indoor unit user identifier in the indoor unit MDT data to obtain a unique cell identifier corresponding to each indoor unit user identifier, so as to analyze the unique cell identifier subsequently, and further screen out indoor unit fixed user MDT data included in the indoor unit MDT data.

More specifically, the method for obtaining the MDT data of the indoor fixed user may be to obtain the base station basic information table and the base station cell neighbor table first, where the base station basic information table and the base station cell neighbor table may be obtained by directly reading a database pre-stored in the server 104, or may be obtained by storing the base station basic information table and the base station cell neighbor table in other servers to request for obtaining. The purpose of obtaining the base station basic information table is to inquire the cell longitude and latitude information of the corresponding cell of each cell identifier in the indoor division fixed user MDT data, and the distance between the corresponding cells of each cell identifier can be calculated by using the cell longitude and latitude information; the purpose of acquiring the neighbor cell list of the base station is to query the cell neighbor information of the corresponding cell of each cell identifier in the MDT data of the indoor division fixed user, and determine whether the cells corresponding to each cell identifier are adjacent or not by using the cell neighbor information; and finally analyzing and extracting the indoor division fixed user MDT data in the indoor division user MDT data through the cell spacing and cell adjacent relation.

In one embodiment, as shown in FIG. 7, step 604 includes:

step 702, obtaining a base station basic information table and a base station cell neighbor table; the base station cell neighbor list comprises cell neighbor information; the base station basic information table comprises cell longitude and latitude information;

step 704, if the number of the cell identifiers after de-duplication is less than or equal to a first number threshold, and the cell identifiers have adjacent cell adjacent information in the base station cell adjacent table, screening out the MDT data of the indoor user identifiers in the indoor user MDT data, and using the MDT data as the indoor fixed user MDT data;

step 706, if the number of the cell identifiers after the duplication removal is greater than or equal to a second number threshold, the cell fixed user MDT data in the cell user MDT data is screened out according to the cell longitude and latitude information of the cell identifiers in the base station basic information table.

The cell neighbor information may refer to cell information having a neighbor relation, for example, cell a is adjacent to cell B.

The longitude and latitude information of the cell may refer to longitude and latitude information of the cell, for example, longitude and latitude information of the cell a is "29 ° 58 ° north latitude, 115 ° east longitude 05'".

Wherein the first number threshold may be a value of 2 in the present embodiment; the second number threshold may be a value of 3 in this embodiment. It will be appreciated that in other embodiments the corresponding threshold may be set in accordance with traffic requirements.

Specifically, the server 104 performs association analysis processing on the obtained base station basic information table and the obtained base station cell neighbor table and the cell identifier after de-duplication, which actually includes:

(1) When the cell identifier corresponding to the indoor user identifier does not exceed the first quantity threshold after the duplication is removed, and the cells corresponding to the cell identifiers are adjacent cells (determined by the cell adjacent information in the base station cell adjacent cell list), the MDT data corresponding to the indoor user identifier can be used as indoor fixed user MDT data, and the server 104 can screen the indoor user MDT data according to the analysis processing.

For example, the first number threshold is 2, when the cell identity corresponding to the single indoor user identity exists Σdeduplication (cell ID ₁ Cell ID ₂ Cell ID _n ) And less than or equal to 2', and the cells represented by the 2 cell identifiers are adjacent cells, the MDT data corresponding to the indoor division user identifier can be used as indoor division fixed user MDT data.

(2) And when the cell identification corresponding to the indoor division user identification is de-duplicated and reaches a second quantity threshold value, acquiring the corresponding cell longitude and latitude information of the cell identification in the base station basic information table, and screening indoor division fixed user MDT data in the indoor division user MDT data by analyzing the cell longitude and latitude information corresponding to each cell identification.

For example, the second number threshold is 3, when the cell identity "Σduplicate removal (cell ID ₁ Cell ID ₂ The cell IDn) is more than or equal to 3", and the latitude and longitude information of the cells corresponding to all the cell identifiers meet the preset conditions, the MDT data corresponding to the indoor unit user identifiers can be used as indoor unit fixed user MDT data.

In one embodiment, as shown in FIG. 8, step 706 includes:

step 802, if the cell identifier has the cell longitude and latitude information meeting the first preset distance threshold range in the base station basic information table, screening out the MDT data of the indoor unit user identifier in the indoor unit user MDT data, and using the MDT data as the indoor unit fixed user MDT data;

step 804, if the cell identifier has the cell longitude and latitude information meeting the second preset distance threshold range in the base station basic information table, obtaining MDT data of the indoor user identifier in a period adjacent to the preset period before and after the preset period, and determining whether the cell identifier corresponding to the indoor user identifier has the cell longitude and latitude information meeting the third preset distance threshold range in the base station basic information table in the period adjacent to the preset period before and after the preset period; and if yes, screening out MDT data of the indoor division user identification in the indoor division user MDT data, and taking the MDT data as the indoor division fixed user MDT data.

The first preset distance threshold range may be a numerical range of 0-400 meters in this embodiment; the second preset distance threshold range may be a numerical range of 400-1000 meters in this embodiment; the third preset distance threshold range may be a numerical range of 0-1000 meters in this embodiment. It will be appreciated that in other embodiments the corresponding threshold may be set in accordance with traffic requirements.

Specifically, when the cell identifier corresponding to the indoor user identifier reaches a second number threshold after the duplication is removed, acquiring the longitude and latitude information of the cell corresponding to the cell identifier in a base station basic information table; if the longitude and latitude information of the cell meets the first preset distance threshold range, the server 104 can directly screen out the MDT data of the indoor division user identifier in the indoor division user MDT data, and the MDT data is used as indoor division fixed user MDT data; if the longitude and latitude information of the cell does not meet the first preset distance threshold range but meets the second preset distance threshold range, MDT data of the indoor user identification in a period adjacent to the preset period can be obtained, whether the longitude and latitude information of the cell identified in each cell in the total period meets the third preset distance threshold range is judged, and if so, MDT data of the indoor user identification in the indoor user MDT data can be screened out and used as indoor fixed user MDT data.

For example, when the second number threshold is 3, the first preset distance threshold range is 0-400 meters, the second preset distance threshold range is 400-1000, and the third preset distance threshold range is 0-1000 meters, the cell identifier corresponding to the indoor user identifier has' sigma de-duplication (cell ID) ₁ Cell ID ₂ Cell IDn) is greater than or equal to 3", and the longitude and latitude information of the cells corresponding to all the indoor partition cell identifiers meets a first preset distance threshold range of 0-400 meters, namely, the distance between the indoor partition cells is within a range of 400 meters, the MDT data corresponding to the indoor partition user identifiers can be used as indoor partition fixed user MDT data.

For another example, if the longitude and latitude information of the cells corresponding to all the cell identifications of the indoor user identification meets the second preset distance threshold range of 400-1000 meters, the MDT data of the target user identification in a period adjacent to the preset period (three periods in total, for example, the preset period is 1 hour of 10:00am-11:00am, the total period is 3 hours of 9:00am-12:00 am) needs to be further acquired, and if the longitude and latitude information of the cells corresponding to the cell identifications in the total three periods meets the third preset distance threshold range of 0-1000 meters, the MDT data corresponding to the indoor user identification can be used as the indoor fixed user MDT data.

It should be noted that, after the server 104 screens out all the indoor fixed subscriber MDT data and further screens out the indoor fixed subscriber MDT data with the cell type being the indoor cell type and corresponding to the indoor fixed subscriber identifier, the server may perform deduplication processing with each indoor fixed subscriber identifier as a primary key to determine the indoor MDT data that can be finally used as a basis for subsequent analysis processing.

In one embodiment, as shown in FIG. 9, step 206 includes:

step 902, acquiring historical room division MDT data corresponding to the room division fixed user identification in a preset period; the historical indoor distribution MDT data comprises historical average fixed user numbers, historical fixed user sampling points, historical user occupation ratios, historical average coverage levels, historical average coverage quality, historical uplink traffic and historical downlink traffic;

step 904, comparing the historical average fixed user number, the historical fixed user sampling point number, the historical user occupation proportion, the historical average coverage level, the historical average coverage quality, the historical uplink traffic and the historical downlink traffic with the room-division MDT data respectively.

Specifically, the preset period may be a history period that is contemporaneous with the MDT data acquisition period, for example, the acquisition period of MDT data is 1 month and 5 days "10:00-11:00 "period, the acquisition period of the historical room division MDT data is 10 for the first three periods (1 month 2-4 days): 00-11:00 "period.

More specifically, acquisition ofThe formula for the historical average fixed number of users includes: history period 1 fixed user number = Σdeduplication (fixed user ID ₁ Fixed user ID ₂ Fixed user ID _n ) The method comprises the steps of carrying out a first treatment on the surface of the History period 2 fixed user number = Σdeduplication (fixed user ID ₁ Fixed user ID ₂ Fixed user ID _n ) The method comprises the steps of carrying out a first treatment on the surface of the History period 3 fixed user number = Σdeduplication (fixed user ID ₁ Fixed user ID ₂ Fixed user ID _n ) The method comprises the steps of carrying out a first treatment on the surface of the Historical average fixed user number=avg (history period 1 fixed user number+history period 2 fixed user number+history period 3 fixed user number).
