Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a method, device, equipment and storage medium for determining the position of a high-speed railway test terminal. Background Art

[0002] With the continuous increase in the operating mileage of domestic high-speed railways, the number of passengers traveling by high-speed railways has increased rapidly. High-speed railways have become the main means of transportation for domestic travel. High-speed railway trains are characterized by high speed and dense users. The fully enclosed metal carriages of high-speed railways have large losses on electromagnetic signals, affecting the quality of wireless signals such as mobile networks and GPS satellites. At the same time, when high-speed railways pass through some special terrains such as mountainous areas, canyons, tunnels, and urban high-rise buildings, GPS terminals cannot receive satellite signals. The above situations will affect the accuracy of GPS satellite positioning and the quality of mobile network communications. In the case of missing GPS positioning data and poor positioning accuracy of the high-speed railway test terminal, the coverage range of the high-speed railway base station and the network quality of the line location cannot be effectively determined due to the loss of support for location information, which brings great difficulty to the optimization and adjustment of high-speed railway network coverage, network parameters, and network expansion.

[0122] Reference Figure 1 , shows a flowchart of the steps of a method for determining the position of a high-speed rail test terminal provided by an embodiment of the present invention, and the method may specifically include the following steps:

[0123] Step 101, obtaining the engineering parameter data and measurement data of the high-speed railway line base station.

[0124] In an embodiment of the present invention, the engineering parameter data of the high-speed railway line base station may include the base station number, cell number, longitude and latitude, and the measurement data may include time, main cell data, neighboring cell data, and location data.

[0125] The base station cell data in the measurement data and the engineering parameter data of the high-speed railway line base station can be correlated and matched to obtain the user terminal information of different stations on the high-speed railway line.

[0126] Specifically, the measurement data can be sorted into time, user number, longitude and latitude, base station_cell number, frequency, RSRP, SINR, TA, neighboring area 1 PCI, neighboring area 1 frequency, neighboring area 1 RSRP, neighboring area 2 PCI, neighboring area 2 frequency, neighboring area 2 RSRP, neighboring area 3 PCI, neighboring area 3 frequency, neighboring area 3 RSRP, neighboring area 4 PCI, neighboring area 4 frequency, neighboring area 4 RSRP, neighboring area 5 PCI, neighboring area 5 frequency, neighboring area 5 RSRP, neighboring area 6 PCI, neighboring area 6 frequency, neighboring area 6 RSRP.

[0127] Step 102, determining the time that the user terminal spends between different base stations on the high-speed railway line based on the engineering parameter data and the measurement data.

[0128] In the embodiment of the present invention, the time at which the user terminal arrives at different base stations on the high-speed rail line is different, and the time at which the user terminal is between different base stations on the high-speed rail line can be determined based on the base station number and measurement data in the collected measurement data.

[0129] Step 103, determining the movement speed of the user terminal at different base stations on the high-speed rail line according to the time the user terminal spends between different base stations on the high-speed rail line.

[0130] In the embodiment of the present invention, the movement speed of the user terminal at different base stations on the high-speed rail line can be calculated respectively according to the time the user terminal spends between different base stations on the high-speed rail line.

[0131] In one embodiment of the present invention, the movement speed of the user terminal in different base stations of the high-speed rail line is determined according to the time the user terminal spends between different base stations of the high-speed rail line, including: obtaining the distance between the base stations of the high-speed rail line; determining the movement speed of the user terminal in different base stations of the high-speed rail line according to the distance between the base stations of the high-speed rail line and the time the user terminal spends between different base stations of the high-speed rail line.

[0132] In an embodiment of the present invention, the distance between different base stations of the high-speed rail line can be obtained, and then the movement speed of the user terminal in different base stations of the high-speed rail line can be calculated based on the rate calculation formula and the obtained distance between the base stations of the high-speed rail line and the time the user terminal spends between different base stations of the high-speed rail line.

[0133] Step 104, determining the high-speed rail user terminal among the user terminals according to the movement speed of the user terminal at different base stations on the high-speed rail line.

[0134] In an embodiment of the present invention, a high-speed rail user terminal refers to a user terminal located on a high-speed rail. Since ordinary user terminals and high-speed rail user terminals have different movement speeds, the high-speed rail user terminal among the user terminals can be determined based on the movement speeds of the user terminals at different base stations on the high-speed rail line.

[0135] In one embodiment of the present invention, a high-speed rail user terminal is determined among user terminals based on the movement speed of the user terminal in different base stations of the high-speed rail line, including: judging whether the movement speed of the user terminal in different base stations of the high-speed rail line is higher than a preset high-speed rail rate threshold; if the movement speed of the user terminal in different base stations of the high-speed rail line is higher than the preset high-speed rail rate threshold, the user terminal is determined as a high-speed rail user terminal.

[0136] In one example, the preset high-speed rail speed threshold can be set to 150km / hour, and the calculated movement speed can be compared with the preset high-speed rail speed threshold. The user terminal with a speed higher than the preset high-speed rail speed threshold can be identified as a high-speed rail user terminal, and the measurement data between the high-speed rail user sites can be further identified as high-speed rail line measurement data, and the measurement data can be marked with a high-speed rail line label.

[0137] Step 105, obtaining the high-speed rail line track geographic information, and determining a corrected high-speed rail line track map based on the high-speed rail line track geographic information and the high-speed rail user terminal.

[0138] In an embodiment of the present invention, the corrected high-speed rail line trajectory map refers to a map generated after precise adjustment and optimization of the original high-speed rail line trajectory. The corrected trajectory map can more accurately reflect the actual situation of the high-speed rail line and provide more reliable basic data for the subsequent high-speed rail test terminal position determination.

[0139] In one embodiment of the present invention, high-speed rail line trajectory geographic information is obtained, and a corrected high-speed rail line trajectory map is determined based on the high-speed rail line trajectory geographic information and the high-speed rail user terminal, including: determining the measurement data of the site where the high-speed rail user terminal is located as the high-speed rail line measurement data; determining a line trajectory point data table based on the high-speed rail line trajectory geographic information; determining a first distance from the longitude and latitude of the high-speed rail line measurement data to the longitude and latitude of the line trajectory point data table; associating the high-speed rail line measurement data to a high-speed rail line trajectory point whose first distance is less than a first preset distance threshold; determining the base station cell with the most high-speed rail line measurement data associated with the high-speed rail line trajectory point as the main service cell of the high-speed rail line trajectory point; and determining a corrected high-speed rail line trajectory map based on the main service cell.

[0140] In the embodiment of the present invention, the high-speed rail line track geographic information is determined according to the high-speed rail line test direction and the line geographic layer, and a line track point data table can be generated according to the station sequence and the preset length interval. The line track point data contains: sequence number, starting station name, end station name, longitude and latitude. Specifically, Table 1 shows a line track point data table provided by the embodiment of the present invention:

[0141]

[0142] Table 1

[0143] The trajectory point data in Table 1 contains: serial number, starting station name, ending station name, longitude and latitude, for example: 1, Dianjiang Station, Liangping South Station, 107.374084, 30.309514.

[0144] After determining the line trajectory point data table, the first distance from the longitude and latitude of the high-speed rail line measurement data to the longitude and latitude of the line trajectory point data table can be calculated, and then the high-speed rail line measurement data can be associated with the high-speed rail line trajectory point that satisfies the first minimum distance with the measurement data and the first distance is less than the preset first preset distance threshold, and then all high-speed rail measurement data associated with the high-speed rail line trajectory point are processed, and the base station cell with the largest number of measurements is selected as the main service cell of the high-speed rail line trajectory point, and the main service cell field such as base station_cell number is added to the line trajectory point data, such as: 28273_27, and then the corrected high-speed rail line trajectory map is further determined based on the main service cell.

[0145] In one embodiment of the present invention, a corrected high-speed rail line trajectory diagram is determined according to a main service cell, including: determining a time advance average value and a reference signal receiving power average value of each trajectory point of the main service cell; determining a first trajectory diagram according to the time advance average value and the reference signal receiving power average value of each trajectory point, the first trajectory diagram including a time advance curve and a reference signal receiving power curve; selecting a first trajectory point set with the largest time advance from the trajectory points of the time advance curve, and selecting a trajectory point with the smallest reference signal receiving power from the first trajectory point set as a time advance far-end signal feature point; generating a far-end signal feature point key-value pair list of the main service cell according to the time advance far-end signal feature point; selecting a second trajectory point set with the smallest time advance from the trajectory points of the time advance curve, and selecting a trajectory point with the largest reference signal receiving power from the second trajectory point set as a time advance near-end signal feature point; generating a near-end signal feature point key-value pair list of the main service cell according to the time advance near-end signal feature point; determining a corrected high-speed rail line trajectory diagram according to the far-end signal feature point key-value pair list and the near-end signal feature point key-value pair list.

Specifically, Figure 2 A first trajectory diagram provided by an embodiment of the present invention is shown. The horizontal axis in the base station target trajectory diagram is the trajectory point serial number, and the trajectory points are arranged from left to right on the horizontal axis in the order of the trajectory point serial number. The vertical axes in the base station target trajectory diagram are TA value and RSRP value, respectively. The TA average value of the trajectory points constitutes the TA curve of the base station target trajectory diagram, and the RSRP average value of the trajectory points constitutes the RSRP curve of the base station target trajectory diagram.

[0147] A first trajectory point set with the largest TA value is selected from the trajectory points associated with the main service cell on the TA curve of the first trajectory diagram of TA-RSRP of the base station, and a trajectory point with the smallest signal strength RSRP is further selected from the first trajectory point set with the largest TA value as the base station TA remote signal feature point, and a TA remote signal feature point key-value pair list of the main service cell of the entire high-speed railway line is generated. The TA remote signal feature point key-value pair includes data: base station_cell number, remote feature trajectory point number, TA value, RSRP value, for example: 28273_27, 2, 3, -92, Then, a second trajectory point set with the smallest TA value is selected from the trajectory points associated with the main service cell on the TA curve of the first trajectory diagram of the base station TA-RSRP, and a trajectory point with the largest signal strength RSRP is further selected from the second trajectory point set with the smallest TA value as the base station TA near-end signal feature point, and a TA near-end signal feature point key-value pair list of the main service cell of the entire high-speed rail line is generated. The TA near-end signal feature point key-value pair contains the following data: base station_cell number, near-end feature trajectory point number, TA value, RSRP value, for example: 28273_27, 4, 1, -87.

[0148] Finally, the corrected high-speed rail line trajectory map is determined based on the far-end signal feature point key-value pair list and the near-end signal feature point key-value pair list.

[0149] In one embodiment of the present invention, a corrected high-speed rail line trajectory map is determined based on a far-end signal feature point key-value pair list and a near-end signal feature point key-value pair list, including: determining a second distance from a trajectory point in a line trajectory point data table to a primary service cell; determining a base station distance distribution map based on the second distance from a trajectory point in a line trajectory point data table to a primary service cell; selecting a trajectory point with the smallest second distance in the base station distance distribution map as a base station near-end position reference point; correcting the position of a trajectory point in the near-end signal feature point key-value pair list through the base station near-end position reference point, and adding a first reference point number to the trajectory point in the corrected near-end signal feature point key-value pair list; selecting a trajectory point with the largest second distance in the base station distance distribution map as a base station far-end position reference point; correcting the position of a trajectory point in the far-end signal feature point key-value pair list through the base station far-end position reference point, and adding a second reference point number to the trajectory point in the corrected far-end signal feature point key-value pair list; forming a trajectory point set according to a trajectory point numbering sequence consisting of the first reference point number and the second reference point number; and determining a corrected high-speed rail line trajectory map based on the trajectory point set.

[0150] In an embodiment of the present invention, the longitude and latitude positions and the main service cell of the line trajectory point data table can be obtained, and combined with the longitude and latitude positions of the base station cell in the high-speed rail engineering parameter data, the second distance between each line trajectory point and the main service cell can be calculated, and a base station distance distribution map of the high-speed rail line trajectory point is generated. For the main service cell of the high-speed rail line trajectory point, for example: 28273_27, the trajectory point with the smallest second distance is selected from the trajectory points associated with the main service cell on the high-speed rail base station distance distribution map as the base station proximal position reference point, and the position of the base station proximal position reference point is used to correct the geographical location of the TA proximal signal feature point corresponding to the main service cell, and a correction feature anchor point number field is added to the TA proximal signal feature point key-value pair, and the base station proximal position reference point number after the position correction of the TA proximal feature trajectory point number is recorded.

[0151] like Figure 3 As shown, the horizontal axis in the base station distance distribution map is the trajectory point number, which is arranged from left to right on the horizontal axis in the order of the trajectory point number. The vertical axis in the high-speed rail base station distance distribution map is the second distance between the trajectory point and the main service cell.

[0152] Furthermore, the trajectory point with the second largest distance can be selected from the trajectory points associated with the main service cell on the high-speed railway base station distance distribution map as the base station remote position reference point, and the base station remote position reference point position can be used to correct the geographical location of the TA remote signal feature point corresponding to the main service cell, and a correction feature anchor point number field is added to the TA remote signal feature point key-value pair to record the base station remote position reference point number after the TA remote feature trajectory point number is corrected.

[0153] Finally, according to the sequence of feature trajectory point numbers formed by the proximal feature trajectory point numbers and the distal feature trajectory point numbers in the TA proximal and distal signal feature point key-value pairs, a trajectory point set consisting of a section of trajectory points between adjacent feature trajectory points is determined, and then based on the trajectory point set, the corrected high-speed rail line trajectory map is determined.

[0154] In one embodiment of the present invention, a corrected high-speed rail line trajectory map is determined based on a trajectory point set, including: determining the distance ratio between the measurement data of each trajectory point in the trajectory point set and the adjacent trajectory points; based on the distance ratio, uniformly mapping the measurement data of each trajectory point to the corrected feature points of the adjacent trajectory points to obtain a corrected high-speed rail line trajectory map.

[0155] In an embodiment of the present invention, the distance ratio between the measurement data associated with the trajectory point set and the adjacent feature trajectory points can be calculated. The distance ratio calculation formula is: distance ratio = distance (MR, feature trajectory point A) / (distance (MR, feature trajectory point A) + distance (MR, feature trajectory point B)), for example: distance ratio = 120 / (120 + 80) = 0.6, according to the distance ratio, the measurement data is evenly mapped to the trajectory points between the feature anchor points of the adjacent feature trajectory points after position correction, and the corrected high-speed rail line trajectory map is obtained.

[0156] like Figure 4 , showing a corrected high-speed rail line trajectory map provided by an embodiment of the present invention, a high-speed rail base station coverage segment sequence is obtained according to the trajectory point processing associated with the main service cell in the corrected high-speed rail line trajectory map, and the high-speed rail base station coverage segment sequence data includes: segment number, base station_cell number, starting point trajectory number, end point trajectory number, near-end trajectory anchor point number, and far-end trajectory anchor point number, wherein the near-end trajectory anchor point number is the base station TA near-end signal feature point selected through the base station correction trajectory map, and the far-end trajectory anchor point number is the base station TA far-end signal feature point selected through the base station correction trajectory map.

[0157] Step 106, obtaining sampling point data of the high-speed rail test terminal.

[0158] In an embodiment of the present invention, network test data generated by a high-speed rail line test terminal can be obtained, and then processed to generate sampling point data, the sampling point data containing: number, test time, base station_cell number, TA, RSRP, SINR, frequency.

[0159] Step 107, determining the location information of the high-speed rail test terminal according to the corrected high-speed rail line trajectory map and sampling point data.

[0160] In the embodiment of the present invention, the location information of the high-speed rail test terminal can be determined through the corrected high-speed rail line trajectory map and sampling point data.

[0161] In one embodiment of the present invention, the location information of the high-speed rail test terminal is determined according to the corrected high-speed rail line trajectory map and sampling point data, including: generating a high-speed rail base station coverage segment sequence according to the trajectory points associated with the main service cell in the corrected high-speed rail line trajectory map; determining the location information of the high-speed rail test terminal according to the high-speed rail base station coverage segment sequence and sampling point data.

[0162] In an embodiment of the present invention, the high-speed rail base station coverage segment sequence can be obtained according to the trajectory points associated with the main service cell in the corrected high-speed rail line trajectory map. The high-speed rail base station coverage segment sequence data may include: segment number, base station_cell number, starting trajectory number, end trajectory number, proximal trajectory anchor point number, and distal trajectory anchor point number, for example: 1, 28273_27, 1, 5, 1, 5.

[0163] In one embodiment of the present invention, the sampling point data includes a test time and a cell number, and the location information of the high-speed rail test terminal is determined according to the high-speed rail base station coverage segment sequence and the sampling point data, including: segmenting the sampling point data according to the test time sequence and the cell number of the sampling point data to obtain test segment data; selecting a target high-speed rail base station coverage segment that matches the cell number of the test segment data in the high-speed rail base station coverage segment sequence; determining a position similarity value between the test segment data and the target high-speed rail base station coverage segment; taking the trajectory anchor point position in the target high-speed rail base station coverage segment whose position similarity value is greater than a preset similarity value as the high-speed rail line position of the sampling point, and generating a test anchor point position list, the test anchor point position list including a feature sampling point number, a trajectory anchor point number, and a position similarity value; mapping continuous test sampling points in the test anchor point position list to the high-speed rail line trajectory point position according to a time interval relationship to obtain the location information of the high-speed rail test terminal.

[0164] In an embodiment of the present invention, for example, the sampling point data is: 1, 2024-7-10 9:31:21, 27734_17, 2, -85, 10, 1850. The high-speed rail test sampling point data is segmented according to the test time sequence of the sampling points and the base station_cell number, and the test segment data is processed to obtain the test segment data. The test segment data contains: segment sequence number, base station_cell number, starting point sampling point number, end point sampling point number, test duration, proximal feature sampling point, and distal feature sampling point. The proximal feature sampling point is a sampling point with the largest signal strength RSRP selected from the sampling point data with the smallest TA value in the test segment, and the distal feature sampling point is a sampling point with the smallest signal strength RSRP selected from the sampling point data with the largest TA value in the test segment.

[0165] Furthermore, the generated high-speed railway base station coverage segment sequence data can be obtained, and the high-speed railway base station coverage segment that matches the base station_cell number of the test segment data is selected. According to the TA value and RSRP value of the sampling point data in the test segment data, the position similarity value between the proximal feature sampling point of the test segment data and the proximal trajectory anchor point of the high-speed railway base station coverage segment, and the position similarity value between the distal feature sampling point of the test segment data and the distal trajectory anchor point of the high-speed railway base station coverage segment are calculated. The position similarity value calculation formula is: Similarity value = W1*(1-Abs((TA feature sampling point-TA trajectory anchor point) / TA trajectory anchor point))+W2*(1-Abs((RSRP feature sampling point-RSRP trajectory anchor point) ... point) / RSRP trajectory anchor point)), where W1 and W2 are weight coefficients, W1+W2=1, for example: W1=0.6, W2=0.4, similarity value=0.6*(1-Abs((3-2) / 3))+0.4*(1-Abs((-91+89) / -91))=0.79, the preset similarity value is 0.80, the trajectory anchor point position with a similarity value greater than or equal to the preset similarity value is selected as the high-speed rail line position of the feature sampling point, the position positioning processing of the feature sampling points of all test segment data is completed, and a test anchor point position data list of the feature test sampling point data is generated, and the test anchor point position data contains: feature sampling point number, trajectory anchor point number, and position similarity value.

[0166] Finally, according to the sequence of feature sampling point numbers in the test anchor point position data list, the continuous test sampling points between adjacent feature sampling point numbers are mapped to the high-speed rail line trajectory point positions according to the sampling point time interval relationship, and the position information of the high-speed rail test terminal on the high-speed rail line is obtained.

[0167] The present invention can accurately calculate the movement speed of the user terminal between different base stations by combining the working parameter data and measurement data of the high-speed railway line base station, and then identify the high-speed railway user terminal, and use the corrected high-speed railway line trajectory map and the sampling point data of the test terminal to achieve accurate positioning of the high-speed railway test terminal, thereby improving the accuracy and reliability of the high-speed railway test terminal position determination; the high-speed railway user terminal can be effectively identified by the movement speed of the user terminal at different base stations of the high-speed railway line, and combined with the high-speed railway line trajectory geographic information, a corrected high-speed railway line trajectory map can be generated, thereby improving the accuracy of the trajectory; the present invention uses the high-speed railway line trajectory geographic information to cover the entire high-speed railway line, and ensure the positioning effect in long-distance, high-speed movement scenarios.
