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 some, not all, embodiments of the present invention. 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 reference numbers in the present application are only used for distinguishing the steps in the scheme and are not used for limiting the execution sequence of the steps, and the specific execution sequence is described in the specification.
The indoor users serve as key groups of wireless communication service objects, network optimization can be assisted by effective identification of the wireless communication service objects to find network problems of indoor scenes in time, resource allocation is intelligently carried out, optimization measures are provided in a targeted mode, and practical significance is achieved for guiding network optimization work. However, due to the particularity of the indoor environment, it is often difficult to realize high efficiency and high accuracy for indoor user identification.
In practical application, network parameters of various indoor positions can be collected in a manual testing mode. For example, a professional network optimization person holds a terminal device to a target building to test the terminal device layer by layer or extract partial floors, so as to obtain network indexes such as coverage, quality difference, uplink and downlink speed and the like in the building. However, this manual testing method requires a lot of manpower and is inefficient, and it is difficult to fully evaluate the building due to the fact that a private site does not allow access to the test, it is difficult to cover all areas in the building when walking in the building, and the like.
If a manual testing method is adopted, each professional can only test 3-5 indoor buildings every day. If the network is to be regularly evaluated and monitored for massive buildings, the workload and the cost are extremely high.
In order to solve the problems in the prior art, the present application provides a method for backfilling data based on measurement reports, as shown in fig. 1, including the following steps:
s11: acquiring minimization drive test data of a target user, wherein the minimization drive test data comprises a geographical position of the target user and a user identifier of the target user;
s12: obtaining at least one measurement report of the target user according to the user identification, wherein the measurement report is associated with the user identification;
s13: judging whether the at least one measurement report meets the measurement report standard corresponding to the indoor user or not based on the MDT data;
s14: and backfilling the geographic position of the target user with the measurement report meeting the measurement report standard corresponding to the indoor user.
In step S11, Minimization Drive Test (MDT) provides a possibility for an operator to collect a dynamic fluctuation process of a wireless network through a commercial terminal, provides a comprehensive reference view for a network optimization, analysis, and diagnosis process, and can partially replace manual Drive Test. The minimization of drive tests data comprises a geographical position of a target user and a user identification of the target user, wherein the geographical position of the target user can be coordinates of the target user and can comprise longitude and latitude of a point location where the target user is located. The user identification of the target user may be an identification code comprising numbers and/or letters, usually the user identification of different users being different at the same time.
In step S12, at least one test report of the target user is obtained according to the user identifier, and typically, each test report includes a user identifier. And if the user identifier in the minimization of drive test data is the same as the user identifier in the measurement report, indicating that the minimization of drive test data and the measurement report are from the same target user. According to the user identification, associated measurement reports from target users corresponding to the minimization of drive test data can be obtained.
In step S13, it may be determined whether the measurement report meets the measurement report standard corresponding to the indoor user based on the minimization of drive test data in various ways, for example, the measurement report may be determined by using parameters such as Angle-of-Arrival (AOA), maximum Time Advanced (TA), Reference Signal Receiving Power (RSRP), and the like. When the number of the measurement reports is multiple, each measurement report may be sequentially determined in this step, and which measurement reports meet the measurement report standard corresponding to the indoor user is determined.
In step S14, the geographical location of the target user is backfilled with measurement reports that meet the measurement report criteria corresponding to the indoor user. Specifically, after the measurement reports meeting the measurement report standards corresponding to the indoor users are determined, the geographical positions of the target users in the minimization of drive test data are backfilled into the measurement reports, so that the measurement reports contain the geographical positions of the target users. Alternatively, the measurement reports may be associated with the geographical location of the target user, such that each measurement report meeting the above criteria corresponds to a geographical location.
Through the scheme provided by the application, the geographical position backfilling can be performed on the measurement reports without positions based on the minimized drive test data, and then the communication conditions of the corresponding areas of the measurement reports can be known, so that targeted optimization measures can be performed on the areas with communication problems. The scheme has high backfilling efficiency and high backfilling data accuracy, and the backfilled measurement report can accurately reflect the communication condition of the position of the target user.
Based on the solution provided in the foregoing embodiment, preferably, the minimization of drive test data includes a signal arrival angle, where, as shown in fig. 2, the foregoing step S13 includes the following steps:
s131: and when the difference value between the signal arrival angle in the measurement report and the signal arrival angle in the minimization of drive test data is within a preset signal arrival angle range, determining that the measurement report meets the measurement report standard corresponding to an indoor user.
In this step, the difference between the signal arrival angle in the measurement report and the reference value is calculated using the signal arrival angle in the minimization of drive test data as the reference value. For example, first, a reference AOA in the minimization of drive test data is determined, then, AOAs in the first measurement report, the second measurement report, and the third measurement report of the acquired target user are determined, and a difference between the AOA in the first measurement report and the reference AOA, a difference between the AOA in the second measurement report and the reference AOA, and a difference between the AOA in the third measurement report and the reference AOA are respectively calculated. The preset signal arrival angle range may be greater than or equal to-30 and less than or equal to 30, and in fact, the preset signal arrival angle range may be adjusted according to actual requirements. And determining the measurement report with the difference value between the AOA and the reference AOA within the preset signal arrival angle range as the measurement report meeting the measurement report standard corresponding to the indoor user.
In the scheme, the arrival direction of the signal of the transmitting node is sensed by a target user, the relative direction or angle between the receiving node and the anchor node is calculated, and then the position of an unknown node is calculated by utilizing a triangulation method or other methods. The positioning algorithm based on the signal arrival angle has low communication overhead and higher positioning precision. When the difference value between the AOA and the reference AOA is within the preset signal arrival angle range, it can be determined that the position of the target user does not change obviously when the target user sends the minimization drive test data and the target user sends the measurement report, so that the wireless communication related parameters in the measurement report can be used for describing the communication condition of the geographic position in the minimization drive test data, and further, corresponding communication optimization measures can be executed according to the communication condition of the area.
Based on the solution provided in the foregoing embodiment, preferably, the minimization of drive test data includes a maximum time advance, where, as shown in fig. 3, the foregoing step S13 includes the following steps:
s132: and when the difference value between the maximum time advance in the measurement report and the maximum time advance in the MDT data is within a preset maximum time advance range, determining that the measurement report meets the measurement report standard corresponding to an indoor user.
In this step, the maximum time advance in the minimization of drive test data is used as a reference value, and a difference between the maximum time advance in the measurement report and the reference value is calculated. For example, a reference TA in the minimization of drive test data is determined, then TAs in the first measurement report, the second measurement report, and the third measurement report of the target user are determined, and a difference between the TA in the first measurement report and the reference TA, a difference between the TA in the second measurement report and the reference TA, and a difference between the TA in the third measurement report and the reference TA are calculated, respectively. The preset maximum time advance range may be greater than or equal to 0 and less than or equal to 78, and in fact, the preset maximum time advance range may be adjusted according to actual requirements. And determining the measurement report of which the difference value between the TA and the reference TA is within the preset maximum time advance range as the measurement report meeting the measurement report standard corresponding to the indoor user.
Preferably, the present solution may also determine whether the measurement report meets a measurement report standard corresponding to an indoor user according to two standards, namely, a maximum time advance in the measurement report and the signal arrival angle. Specifically, when the difference between the AOA in the measurement report and the reference AOA is within the preset signal arrival angle range, and the difference between the TA in the measurement report and the reference TA is within the preset maximum time advance range, it is determined that the measurement report meets the measurement report standard corresponding to the indoor user.
In this scheme, the maximum time advance may refer to a difference between an actual time when a signal transmitted by a target user reaches a base station and a time when a mobile station signal reaches the base station when the distance between the target user and the base station is assumed to be 0. When the difference value between the TA and the reference TA is within the preset signal arrival angle range, it can be determined that the location of the target user does not change significantly when the target user sends the minimization drive test data and the target user sends the measurement report, so that the wireless communication related parameters in the measurement report can be used for describing the communication situation of the geographic location in the minimization drive test data, and further, corresponding communication optimization measures can be executed according to the communication situation of the area.
Based on the solution provided in the foregoing embodiment, preferably, the geographic location of the target user is located in an area where a target building is located, a shortest distance between the geographic location and the periphery of the target building is smaller than a preset distance, and the minimization of drive test data includes target reference signal received power, where, as shown in fig. 4, the foregoing step S13 includes the following steps:
s133: and when the reference signal received power in the measurement report is not greater than the target reference signal received power, determining that the measurement report meets the measurement report standard corresponding to the indoor user.
The reference signal received power, also denoted as RSRP, is one of the key parameters that may represent the radio signal strength in a communication network and the physical layer measurement requirements, and is the average of the received signal power over all resource elements that carry the reference signal within a certain symbol.
Generally, the reference signal received power of an electronic device is not uniform in various areas within a building, and in areas near the edges of the building, such as the window edges, the signal is stronger than the signal inside the building. This is because signals from electronic equipment located near the window can propagate to the communication base station through the outer wall of the building or through the window to the outside of the building. Signals from electronic equipment located inside a building often need to pass through multiple walls to reach the outside of the building and propagate to a communication base station. When the signal passes through the wall, the signal strength is weakened, and the more walls and obstacles pass through, the more the signal is reduced. Similarly, when the base station sends a signal to the electronic device in the building, if the electronic device is located at the window side of the building, the reference signal receiving power of the electronic device is high, and the communication quality is relatively good, and if the electronic device is located inside the building, the reference signal receiving power of the electronic device is low, and the communication quality is relatively poor.
In the scheme of the application, whether the target user is indoors is determined according to the reference signal received power in the measurement report. In practical application, the target building may be determined first by combining with the map, for example, the area occupied by the target building may be determined according to the map, and the outline of the periphery of the target building on the map may be determined. The users whose geographical locations are within the area occupied by the target building are then determined, and which user or users are within the area occupied by the target building can be determined based on the coordinates of the outline of the target building. After the users located in the target building are determined, the target users are determined according to the shortest distance between the users and the outline of the target building, and the users in the building, the shortest distance between which and the periphery of the target building is smaller than the preset distance, are determined as the target users. The preset distance can be preset according to actual conditions, for example, the preset distance can be determined by combining factors such as the occupied area of a target building, the material of the outer wall of the target building, the position of the building and the like.
The determined target user is located near the window of the target building and closer to the outer wall of the target building, and the reference signal received power of the target user is stronger than that of other users in the target building. In step S133, the reference signal received power in the measurement report is not greater than the target reference signal received power, and it is determined that the measurement report meets the measurement report standard corresponding to the indoor user.
In addition, the scheme of the application can also determine whether the measurement report meets the measurement report standard corresponding to the indoor user based on the reference signal received power in combination with the AOA and/or the TA in the measurement report. Specifically, if the present solution determines whether the measurement report meets the measurement report standard corresponding to the indoor user by combining the reference signal received power, the AOA, and the TA, when the reference signal received power in the measurement report is not greater than the target reference signal received power, the difference between the AOA and the reference AOA in the measurement report is within the preset signal arrival angle range, and the difference between the TA and the reference TA in the measurement report is within the preset maximum time advance range, it is determined that the measurement report meets the measurement report standard corresponding to the indoor user.
In the scheme provided by the application, when the reference signal received power in the measurement report is not greater than the target reference signal received power, it can be determined that when the target user sends the minimization of drive test data and the target user sends the measurement report, the target user is indoors and the position of the target user is not changed obviously. And then, backfilling the position information in the minimization of drive test data into the measurement report, wherein the wireless communication related parameters in the measurement report can be used for describing the communication condition of the geographic position in the minimization of drive test data, and further, corresponding communication optimization measures can be executed according to the communication condition of the area.
Based on the solution provided by the above embodiment, preferably, when the number of the measurement reports of the target user is multiple, as shown in fig. 5, the method further includes the following steps:
s15: determining an occupied cell set of the target user according to a plurality of measurement reports, wherein the occupied cell set comprises cells occupied by the target user when the target user sends the measurement reports, and each cell corresponds to at least one measurement report;
s16: sequencing the cells in the occupied cell set according to the number of the measurement reports corresponding to the cells, and determining a first target cell with a first preset number according to a sequencing result;
wherein, the step S14 includes the following steps:
s141: and when the ratio of the number of the measurement reports corresponding to the first target cell to the total number of the measurement reports of the target user is greater than a preset measurement report ratio, backfilling the geographical position of the target user for each measurement report meeting the measurement report standard corresponding to the indoor user.
In this scheme, the number of measurement reports of the target user is multiple, and these measurement reports may be periodically and actively reported by the target user. In step S15, the cells occupied by each user when sending each measurement report may be determined according to a plurality of measurement reports, and the occupied cell set of the target user may be determined according to the cells. Each measurement report corresponds to one cell in the occupied cell set, and one cell in the occupied cell set may correspond to one or more measurement reports.
Subsequently, in step S16, the cells in the occupied cell set are sorted, and the cells are sorted in descending order of the number of corresponding measurement reports. In the ranking result, the cell ranked at the top is the cell with the largest number of corresponding measurement reports, and the cell ranked at the last is the cell with the smallest number of corresponding measurement reports. Then, at least one first target cell is determined according to the sorting result, and a plurality of cells ranked at the top can be determined as the first target cell in general. For example, five cells ranked in the top five are determined as the first target cell.
Next, in step S141, the total number of measurement reports corresponding to the first target cell is determined. For example, there are five first target cells, the number of measurement reports corresponding to the five first target cells is determined, and then the sum of the number of measurement reports corresponding to the first target cells is determined as the number of measurement reports corresponding to the first target cells. Meanwhile, the total number of measurement reports of the target user is determined, which may be the number of all received measurement reports including the user tag of the target user. The total number of measurement reports of the target user may also be understood as the sum of the number of measurement reports corresponding to each cell in the above-mentioned occupied cell set.
In this step, a ratio of the number of measurement reports corresponding to the first target cell to the total number of measurement reports of the target user is calculated, and if the ratio is greater than a preset measurement report ratio, it indicates that the cell occupied by the target user is relatively fixed, and further indicates that the geographic location of the user has no significant change, and at this time, the geographic location of the target user may be refilled with each measurement report meeting the measurement report standard corresponding to the indoor user.
In practice, the signal coverage area of each base station is limited, and if a user is in the signal coverage area of the base station, the user tends to occupy the base station for communication. If a user moves out of the signal coverage area of a base station, a new base station is occupied. If the target user moves continuously and the geographical location changes greatly, the number of base stations occupied by the target user should be large, and after the above sorting, the number of measurement reports corresponding to the first target cell is lower in the total number. At this time, since the user is moving continuously, the location in the minimization of drive test data is often not the location where the user sent the measurement report, and the geographic location of the target user cannot be backfilled with the measurement report at this time.
According to the scheme provided by the application, whether the target user moves in a large range or not can be further confirmed through the number of the cells occupied by the target user when the measurement report meets the measurement report standard corresponding to the indoor user, so that the accuracy of backfilling the geographical position of the target user is improved, and the accuracy of information in the backfilled measurement report is improved.
Based on the solution provided in the foregoing embodiment, preferably, when the number of the measurement reports of the target user is multiple, as shown in fig. 6, the method further includes:
s17: determining an occupied cell set of the target user according to a plurality of measurement reports, wherein the occupied cell set comprises cells occupied by the target user when the target user sends the measurement reports, and each cell corresponds to at least one measurement report;
s18: determining the time length for the target user to occupy each cell in the occupied cell set according to the measurement report corresponding to the cell;
s19: sequencing the cells in the occupied cell set according to the time length of each cell occupied by the target user, and determining a second preset number of second target cells according to the sequencing result;
wherein, the step S14 includes the following steps:
s142: and when the ratio of the time length of the target user occupying the second target cell to the time length of the target user occupying each cell in the occupied cell set is greater than the preset occupied time length ratio, backfilling the geographical position of the target user for each measurement report which accords with the measurement report standard corresponding to the indoor user.
In step S17, the cell occupied by each user when sending each measurement report may be determined according to a plurality of measurement reports, and the occupied cell set of the target user may be determined according to the cells. Each measurement report corresponds to one cell in the occupied cell set, and one cell in the occupied cell set may correspond to one or more measurement reports.
Subsequently, in the above step S18, the plurality of cells in the occupied cell set are sorted, and the cells are sorted in the order of the occupied cell market from long to short. In the sorting result, the cell ranked at the top is the cell with the longest occupied time of the target user, and the cell ranked at the last is the cell with the shortest occupied time of the target user. Then, at least one second target cell is determined according to the sorting result, and a plurality of cells ranked at the top can be determined as the second target cell in general. For example, the first three cells are determined as the second target cell.
Next, in step S142, the total duration of the target user occupying the second target cell is determined. For example, there are three second target cells, the time lengths for the target user to occupy the three second target cells are respectively determined, and then the three time lengths are added to obtain the total time length for the target user to occupy the second target cell. And simultaneously, determining the total time length of the target user occupying each cell in the occupied cell set. A
And then, calculating the ratio of the time length of the target user occupying the second target cell to the total time length of each cell, if the ratio is greater than the preset occupied time length ratio, indicating that the cell occupied by the target user is relatively fixed, further indicating that the geographic position of the user has no obvious change, and backfilling the geographic position of the target user for each measurement report meeting the measurement report standard corresponding to the indoor user.
In fact, if the target user moves continuously and the geographic location changes greatly, the time length that the target user occupies each base station is short, and after the above sorting, the time length that the target user occupies the second target cell is lower in the total time length. At this time, since the user is moving continuously, the location in the minimization of drive test data is often not the location where the user sent the measurement report, and the geographic location of the target user cannot be backfilled with the measurement report at this time.
According to the scheme provided by the application, whether the target user moves in a large range or not can be further confirmed through the time length of the target user occupying the cell when the measurement report meets the measurement report standard corresponding to the indoor user, so that the accuracy of backfilling the geographical position of the target user is improved, and the accuracy of information in the backfilled measurement report is improved.
Based on the solution provided by the above embodiment, as shown in fig. 7, the step S11 includes the following steps:
s111: acquiring minimization drive test data of a target user at a first moment;
wherein the method further comprises the steps of:
s20: at a second moment, acquiring at least one first measurement report to be backfilled of the target user according to the user identification, wherein the time interval between the first moment and the second moment is greater than a preset time interval;
s21: and judging whether the first measurement report meets the measurement report standard corresponding to the indoor user or not according to the backfilled second measurement report, and backfilling the geographical position in the second measurement report for the first measurement report meeting the measurement report standard corresponding to the indoor user, wherein the time for acquiring the second measurement report is after the first time and before the second time.
In order to further improve the accuracy of backfilling, the data backfilling is carried out according to the time for acquiring the minimization of drive test data and the measurement report. In step S111 of the present embodiment, the minimization of drive test data of the target user is obtained at the first time. Then, in step S20, a first measurement report to be refilled is obtained at a second time, the preset time interval in this step may be preset according to practical situations, and in general, if the accuracy of the backfilled data is to be improved, the time interval may be set to be shorter, that is, the measurement report is backfilled only for the measurement report received in a short time after the minimization of drive test data is received and the measurement report meets the measurement report standard corresponding to the indoor user.
However, the short preset time interval may cause the backfill rate of the measurement reports to be reduced, so that the number of the backfilled measurement reports is reduced, and the obtained data may not be enough to judge the actual communication condition of an area. If the predetermined time interval is long, a large number of measurement reports may be backfilled with data, but this may cause the accuracy of the backfilled geographic location to be degraded, and thus the communication-related parameters in the measurement reports may not accurately characterize the communication condition of an area. Optionally, the preset time interval may be determined according to the number of communication parameters available in one area, and if the currently acquired data is more, the actual communication quality of one area may be substantially determined, and then a shorter preset time interval may be set to improve the data accuracy. If the currently acquired data is less, a longer preset time interval can be set to increase the data volume and basically grasp the communication quality of an area.
In step S21, since the time interval between the time when the minimization of drive test data is acquired and the time when the measurement report to be backfilled is acquired is long, it may be determined whether to backfill the measurement report to be backfilled based on the already backfilled measurement report.
