Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to an antenna feeder system adjustment method, an antenna feeder system adjustment apparatus, an electronic device, and a storage medium.
Background
The antenna, which is an indispensable part of wireless communication, has a basic function of radiating and receiving radio waves. In order to make the main lobe direction of the antenna feed system of the base station point to the direction in which the user demand is concentrated as much as possible, so that the user can obtain a base station useful signal as strong as possible, and simultaneously suppress the same-frequency and adjacent-frequency interference signals, so that the user can obtain gain as large as possible in the service using process, and the user perception is ensured, the antenna feed system needs to be adjusted.
After the initial network construction of the conventional mobile communication system is completed, the base station antenna feeder system of the whole network is generally adjusted according to a propagation model used in network planning, so that the network planning of each batch of newly-added network-accessing base stations is parameters such as an antenna feeder azimuth angle, a downtilt angle, a half-power angle and the like which are obtained by strictly calculating according to simulation planning. However, since the mobile communication construction speed is fast, the antenna feeder system adjustment is not performed on the existing base station after each batch of base stations are constructed and accessed to the network, which causes the situations of wireless signal overlapping coverage, cross-area coverage and the like, and the later optimization adjustment is usually only local, so that it is difficult to perform uniform adjustment on the network antenna feeder from the whole network level.
In some cases, antenna feeder system adjustments may also be made based on user complaints. For example, the aggregation degree of complaints reflected by the user is roughly judged according to the information that the coverage signals reflected in the complaints of the user are weak, then a field test is carried out to find out that the signal of the base station in the signal difference region reflected by the user is relatively strong, and the signal strength is improved by optimally adjusting the antenna feeder azimuth angle or the downtilt angle of the base station. However, the weak coverage reflected by the complaints of the users cannot accurately distinguish the complaints from the general weak coverage, and the users cannot be accurately positioned, so that the adjustment process of the base station antenna feeder system is judged by estimation, and the adjustment process may have a large deviation, and in addition, the use perception of other users is influenced in the adjustment process.
In some cases, antenna feeder system adjustments may also be made based on weak coverage or overlapping coverage in road testing. For example, in the road test process, a weak coverage road section or a road section with overlapped coverage and without a master control cell is found, a test instrument is used for repeatedly testing on the road to determine a relatively strongest base station signal, and the signal strength is improved by optimally adjusting the antenna feeder azimuth angle or the downward inclination angle of the base station. The base station antenna feeder system adjusting scheme can be accurately implemented by adjusting the azimuth angle or the downward inclination angle of the antenna feeder of the relevant base station according to the record of the road test, however, the mobile user service demand model indicates that 70% of user demands occur indoors and are not on outdoor roads, and the traditional optimization method using the road test as the base station antenna feeder system adjusting basis for communication is made on the basis of using the road test index as the examination basis and cannot really meet the service demands of users.
In some cases, antenna feeder system adjustments based on handoff coverage may also be made. For example, in a road test or a fixed point test, a cross-area coverage signal of a base station far away from the test point is found, co-channel interference is caused to base station signals near the test point, a relatively strong base station signal in the signals of the near base station near the test point is found through a field test, and the signal strength is improved by optimally adjusting an antenna feed azimuth angle or a down inclination angle of the base station. However, the road test or the spot test cannot find all the handover coverage points, and there is no method for determining whether there is handover coverage in the area where the road test or the spot test cannot.

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.
First, technical terms involved in the present invention will be briefly described below.
MR (Measurement Report) is one of the main bases for evaluating the quality of a wireless environment. MR is a method for transmitting data once every 480ms (470 ms on a signaling channel) on a traffic channel, and for GSM (Global System for Mobile Communication), MR is a main means for a network side to obtain terminal wireless information, and the wireless information mainly includes two parts: uplink signal information and downlink signal information. For example, the MR measurement report data in the embodiment of the present invention may be a measurement report generated by calculation in a Radio resource management process, and the measurement report may be from a physical layer of a UE (User Equipment) and an eNodeB (Evolved Node B, a name of a base station in LTE is sometimes abbreviated as eNB), an RLC (Radio Link Control, Radio Link layer Control) layer. The original measurement data is either reported to the OMC-R base station subsystem operation maintenance center through statistical calculation (statistics can be realized on eNodeB or OMC-R) to be stored in a statistical data form, or directly reported to the OMC-R to be stored in a sample data form.
The present invention will be described in detail with reference to the following examples.
Fig. 1 is a schematic flow chart of an antenna feeder system adjustment method according to an embodiment of the present invention. As shown in fig. 1, an antenna feeder system adjusting method includes: s110 to S130.
In S110, MR measurement report data is acquired, and the position information of the MR sampling points is obtained based on the position information of the base station acquiring the MR measurement report data and the direction arrival angle information AOA and the time advance TA of the MR sampling points in the MR measurement report data.
In some examples, partial data information of the MR measurement report data is given in table 1.
TABLE 1 partial data of MR measurement report data
Aoa (Angle of Arrival) in table 1 defines an estimated Angle of a user counterclockwise with respect to a reference direction.
In some examples, the AOA value range is given in table 2, e.g., one interval of 0 degrees to less than 5 degrees, corresponding to mr.aoa.00; 355 degrees to less than 360 degrees is an interval corresponding to mr.aoa.71, and so on. In some examples, it may be specified that the reference direction should be north, counterclockwise, and the reported value range may be: and 0-719, the distribution precision of the measured data interval can be 0.5 degrees, the direction of the user can be determined, and the direction positioning of the user is realized.
TABLE 2 AOA value ranges
Time Advance (TA) in table 1 may be defined as the time for the UE to adjust uplink transmission of the primary cell PUCCH/PUSCH/SRS. The specific calculation method may be: in the random access process, the eNodeB determines a time advance value by measuring a received pilot signal, wherein the time advance value range is (0,1, 2.., 1282) × 16 Ts; in the RRC connected state, the eNodeB determines a TA adjustment value for each UE based on measuring uplink transmissions of the corresponding UE, which adjustment value ranges from (0,1,2,.., 63) × 16 Ts. The latest time lead obtained this time is the sum of the time lead recorded last time and the adjustment value obtained by the measurement of the eNodeB this time.
In some examples, the TA value range is given in table 3, e.g., one interval every 16Ts from 0 to 192Ts, corresponding to mr.tadv.00 to mr.tadv.11; an interval from 192Ts to 1024Ts every 32Ts, corresponding to MR.Tadv.12 to MR.Tadv.37; every 256Ts from 1024Ts to 2048Ts is an interval corresponding to MR.Tadv.38 to MR.Tadv.41; each 1048Ts is an interval from 2048Ts to 4096Ts, corresponding to mr.tadv.42 and mr.tadv.43; ts greater than 4096 is an interval corresponding to mr. tadv.44.

TA characterizes the distance between the UE and the antenna port. The distance corresponding to the TA command value is calculated with reference to 1 Ts. The time advance distance corresponding to 1Ts is equal to: (3 x 10 x 8 x 1/(15000 x 2048))/2 ═ 4.89 m. Meaning the distance is the propagation speed (speed of light) 1Ts/2 (sum of up and down paths). The TA range is 0-1282, and according to the TA value in the RAR (random access response), the UE adjusts the uplink transmission time Nta to TA 16, and the value is constant positive. For example: TA is 1, Nta is 1, 16Ts, and the characterized distance is 16, 4.89m, 78.12m, and at the same time, the maximum access distance between the UE and the network is 1282, 78.12m, 100.156km, and the distance accuracy is 78.12 m.
In some examples, the location information of the base station may be GPS latitude and longitude information of the base station. And acquiring the longitude and latitude information of the MR sampling points based on the GPS longitude and latitude information of the base station for acquiring the MR measurement report data, the direction arrival angle information AOA of the MR sampling points in the MR measurement report data and the time advance TA.
In some examples, the maximum user location of 840 sampling points can be obtained in a theory of 1 hour and 10 minutes according to the MR measurement report data, and the longitude and latitude information of the user activity center is obtained by utilizing the longitude and latitude average value of all the user location.
For example, obtaining latitude and longitude information of MR sampling points may be: sample point 1: 113. x, 34. x; sample point 2: 113. x, 34. x; sample point 3: 113. x, 34. x; … … sample point n: 113.*****,34.*****.
The latitude and longitude information of the user activity center point can be obtained based on the following formula:
in S120, clustering the position information of the difference points in the MR sampling points in the preset range by adopting a clustering algorithm to obtain a difference point position clustering set Mi。
In some examples, to filter out the difference points in the MR sampling points, before S120, the method may further include:
and recording sampling points of which the Reference Signal Received Power (RSRP) of the main serving cell is lower than a threshold value in the MR measurement report data as difference points.
The mr.rsrp (Reference Signal Receiving Power) in the collected MR measurement report data is one of the key parameters that can represent the wireless Signal strength in the LTE network and the physical layer measurement requirement, and is the average value of the received Signal Power on all REs (resource elements) that carry Reference signals within a certain symbol. Is a main index reflecting the coverage of the serving cell.
In some examples, it is desirable to select a suitable range of MR sample points as the range of original MR sample points for difference selection and clustering. Therefore, before S120, the method may further include:
based on number threshold value N of preset sampling points1And a preset sampling point distance threshold value N2Determining MR sampling points of a preset range, wherein the preset sampling points are away from a threshold value N2And obtaining the central sampling point according to the position information of the MR sampling point for the distance threshold value which is required to be met by the MR sampling point in the preset range and is away from the central sampling point.
In some examples, a K-means clustering algorithm may be adopted to perform position information clustering on difference points in MR sampling points of a preset range to obtain a difference point position clustering set Mi。
For example, the distance between each sampling point and each other can be calculated according to the GPS longitude and latitude information of the MR sampling points, and the distance between each sampling point and a central sampling point is calculated to be lower than a threshold N by using a K-means clustering algorithm2Is classified into a set MiThe minimum required number N of MR sampling points of each difference point position clustering set can be set1。
In some examples, cluster set M is clustered at the computing difference point locationiIn order to improve the accuracy of the adjustment of the antenna feeder system, the method for adjusting the antenna feeder system may further include:
comparing average uplink transmission power margin PHR of MR sampling points in MR measurement report data with preset value N4；
If the average uplink transmission power margin PHR of the MR sampling points in the MR measurement report data is lower than the preset value N4Then the downlink power value is increased.
In some examples, it can be appreciated that the average PHR (Power Head Room) at the MR sample points is below a threshold value N4And according to the uplink and downlink balance principle, the situation that the downlink power is increased firstly to improve the RSRP of the coverage reference signal of the MR sampling point can be considered.
In S130, collecting and difference point position clustering set MiCorresponding primary relevant cell set CiAntenna feeder value of the first target main relevant cellClustering set M for calculating horizontal lobe normal and vertical lobe normal of antenna of target main relevant cell and difference point positioniThe azimuth angle value and the declination angle value of the antenna feed value of the first target main relevant cell to be adjusted are obtained.
In some examples, the selection of the first target primary relevant cell may be obtained by:
before S130, a set M of clusters of difference positions is calculatediCorresponding primary relevant cell set CiAccording to the primary relevant cell set CiThe ratio of the intermediate difference point is from high to low to the main related cell set CiAnd sequencing and determining the nth main related cell in the sequencing as the nth target main related cell. For example, it may be in terms of primary associated cell set CiThe ratio of the intermediate difference point is from high to low to the main related cell set CiAnd sequencing, determining the 1 st main related cell in the sequencing as a first target main related cell, and determining the 2 nd main related cell in the sequencing as a second target main related cell.
In some examples, a primary set of related cells C may be providediThe longitude and latitude positions (x, Y) of the cell A are based on the position of the base station as a reference system, and the true north direction is the Y axis. For example, the a cell is a first target primary relevant cell.
Cluster set MiThe preset position in (1) may be a difference position clustering set MiThe longitude and latitude position (x1, y1) of the center; clustering set M of difference point positionsiThe central effective range is the primary associated cell set CiThe antenna direction angle of the antenna feed system of the cell A is taken as the center, and the positive and negative 90 degrees are effective ranges; calculating the counterclockwise angle α from the north to the MR sampling point under different conditions can be classified as the following:
case 1: if x1> x and y1> y, then the MR sample point is in the first quadrant.
According to tan α ═ x1-x)/(y1-y), α ═ arctan [ (x1-x)/(y1-y) ], then the MR sampling point is away from the north and the counterclockwise direction angle is α;
case 2: if x1> x and y1< y, then the MR sample point is in the second quadrant.
According to tan α ═ y1)/(x-x1), α ═ arctan [ (y-y1)/(x-x1) ], then the MR sampling point is away from north by an angle α +90 ° counterclockwise;
case 3: if x1< x and y1< y, then the MR sampling point is in the third quadrant. According to tan α ═ x1)/(y 1), α ═ arctan [ (x-x1)/(y-y1) ], then, the MR sampling point is at an angle α +180 ° counterclockwise from true north;
case 3: if x1< x and y1> y, then the MR sample point is in the fourth quadrant.
According to tan α ═ x1)/(y1-y), α ═ arctan [ (x-x1)/(y1-y) ], then the MR sampling point is located 360 ° - α counterclockwise from true north.
In the method for adjusting the antenna feeder system provided by the embodiment of the invention, the position information of the MR sampling points is obtained by the position information of the base station based on the collected MR measurement report data, the direction arrival angle information AOA and the time advance TA of the MR sampling points in the MR measurement report data, and a clustering algorithm is adopted to obtain the difference point position clustering set, so that the adjustment of the antenna feeder system from the whole network layer is facilitated, and the conditions of overlapping coverage and cross-area coverage of wireless signals are effectively avoided. And because the scheme is based on the analysis and adjustment of the user equipment by using the perceived opportunity data condition, the problem of inaccurate analysis and adjustment of the antenna feed system caused by uneven or omitted data acquisition can be effectively avoided.
Different from the prior art, in the prior art, the information that the coverage signal is weak and is reflected in the complaint of the user or the signal strength data obtained in the road test process can only be used for roughly evaluating the wireless environment quality in a certain area or roughly adjusting the antenna feeder system, so that the problems of inaccurate analysis and adjustment of the antenna feeder system caused by uneven data acquisition or omission easily occur. And after the initial construction of the network is completed, the traditional mobile communication system adjusts the whole network base station antenna feeder system according to the propagation model used in the network planning, and because the construction speed of the mobile communication is very high, the antenna feeder system adjustment is not performed on the existing base stations after each batch of base stations are constructed and accessed, and the problems of wireless signal overlapping coverage and cross-area coverage exist.
Similarly, the target primary associated cell is given a name for convenience of explanation of specific operations. In other embodiments of the present invention, similar to the above, the same names are given for convenience of description and specific operations, and are used for convenience of description and not for essential limitation. There is no longer a single row.
In some examples, in order to further improve the accuracy of the adjustment of the antenna feeder system, the method for adjusting the antenna feeder system may further include a verification process.
Fig. 2 is a schematic flow chart of an antenna feeder system adjusting method according to another embodiment of the present invention, and as shown in fig. 2, the antenna feeder system adjusting method may further include: s210 to S240.
In S210, based on the difference position clustering set obtained multiple times, an azimuth value and a downtilt value of the antenna feed value of the nth target main relevant cell, which are obtained through multiple computations, to be adjusted are respectively compared with a preset angle range.
In S220, it is determined whether the azimuth value and the downtilt value of the antenna feed value of the nth target main relevant cell, which are obtained through multiple calculations, that need to be adjusted are both within a preset angle range. If so, in S230, an average value of azimuth angle values to be adjusted of the antenna feed values of the nth target main relevant cell obtained through multiple calculations and an average value of downtilt angle values to be adjusted of the antenna feed values of the nth target main relevant cell obtained through multiple calculations are respectively obtained, so as to finally determine the azimuth angle values and downtilt angle values to be adjusted of the antenna feed values of the nth target main relevant cell.
Otherwise, S240 is entered, the azimuth angle value to be adjusted of the antenna feed value of the nth target main relevant cell obtained by multiple computations within the preset angle range is selected as the azimuth angle value to be adjusted of the antenna feed value of the nth target main relevant cell, the downtilt angle value to be adjusted of the antenna feed value of the nth target main relevant cell obtained by multiple computations within the preset angle range is selected as the downtilt angle value to be adjusted of the antenna feed value of the nth target main relevant cell, and the azimuth angle value to be adjusted and/or the downtilt angle value to be adjusted of the antenna feed value not within the preset angle range is/are based on the difference position value corresponding to the azimuth angle value to be adjusted of the antenna feed value not within the preset angle range and/or the downtilt angle value to be adjusted of the antenna feed valueCollecting and collecting the (N + 1) th target main relevant cell, and calculating the azimuth angle value and the downtilt angle value of the (N + 1) th target main relevant cell, wherein the antenna feed value of the (N + 1) th target main relevant cell needs to be adjusted, and N +1 is less than or equal to a preset value N3。
In some examples, in S210, the azimuth value and the downtilt value to be adjusted for the antenna feed value of the first target primary relevant cell obtained through multiple computations may be respectively compared with a preset angle range based on the difference position clustering set obtained through multiple computations. Wherein the preset angle range may be 0 ° to 90 °.
In S220, it may be determined whether the azimuth angle value and the downtilt angle value, which are to be adjusted, of the antenna feed value of the first target main relevant cell obtained through multiple computations are both within a preset angle range.
If so, in S230, an average value of azimuth angle values to be adjusted of the antenna feed values of the first target main relevant cell obtained through multiple calculations and an average value of downtilt angle values to be adjusted of the antenna feed values of the first target main relevant cell obtained through multiple calculations are respectively obtained, so as to finally determine the azimuth angle values and downtilt angle values to be adjusted of the antenna feed values of the first target main relevant cell.
Otherwise, the operation goes to S240, selecting an azimuth value to be adjusted of the antenna feed value of the first target main relevant cell obtained through multiple computations within the preset angle range as the azimuth value to be adjusted of the antenna feed value of the first target main relevant cell, selecting a downtilt value to be adjusted of the antenna feed value of the first target main relevant cell obtained through multiple computations within the preset angle range as the downtilt value to be adjusted of the antenna feed value of the first target main relevant cell, and calculating an azimuth value to be adjusted and a downtilt value to be adjusted of the antenna feed value of the second target main relevant cell based on the difference position cluster set and the second target main relevant cell corresponding to the azimuth value to be adjusted of the antenna feed value not within the preset angle range and/or the downtilt value to be adjusted of the antenna feed value.
In some examples, when it is determined that the azimuth angle value and the downtilt angle value of the antenna feed value of the second target main relevant cell obtained through multiple calculations and needing to be adjusted are not both within the preset angle range, selecting the azimuth angle value and the downtilt angle value within the preset angle rangeAnd calculating the azimuth angle value to be adjusted of the antenna feed value of the third target main relevant cell based on the difference point position clustering set and the third target main relevant cell corresponding to the azimuth angle value to be adjusted of the antenna feed value of the second target main relevant cell not in the preset angle range and/or the declination angle value to be adjusted of the antenna feed value. And so on until the ordering of the target main related cell is more than N3Therefore, more accurate adjustment value of the antenna feeder system is obtained.
