Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.

In the description of the present application, unless otherwise indicated, the meaning of "a plurality" means two or more.

At present, with the development of mobile internet, more and more base stations are built by operators, overlapping coverage between the base stations is also more and more, and in an area where the overlapping coverage has serious influence, throughput performance of end users is greatly influenced. Statistical results of network optimization test data show that compared with areas not affected by overlapping coverage, the overlapping coverage area has more than 70% of performance loss, and as the overlapping coverage degree is increased, the performance loss caused by co-channel interference is further increased.

In addition, from the influence scope of overlapping coverage, the proportion occupied by different scenes is different, the site height and the site distance in the actual network are different from those of an ideal cellular network, the building fluctuation in the coverage area of the actual network is variable, and the influence on signal propagation is various, so that the overlapping coverage problem is necessarily present. With the increase of the overlapping coverage, the planning index of network construction cannot be reached, and the use experience of users is greatly influenced.

In the prior art, when the overlapping coverage is analyzed, MR data acquisition is performed first to obtain a long term evolution measurement report (long Term Evolution Measurement Report, LTE MR) data file and a cell information table; the method comprises the steps of carrying out cell overlapping coverage analysis and screening, respectively forming overlapping adjacent cell pairs by the screened overlapping adjacent cells and a main cell, calculating weights of the overlapping adjacent cell pairs according to the number of signal points of the overlapping adjacent cells, determining the priority of the overlapping adjacent cells according to weight sequencing, carrying out coverage distance analysis on cells after the weight sequencing, and determining high overlapping coverage cells to be optimized; finally, multi-factor association analysis is carried out on the cell, including weak coverage association analysis, useful signal duty ratio analysis and user concentration association analysis, and maintenance personnel are notified to schedule processing, and waiting for the maintenance personnel to process consumes a lot of time, so that the overall processing process is low in efficiency.

In order to solve the problem of low processing efficiency of the overlapping coverage area network in the prior art, the application provides an overlapping coverage processing method, which can firstly acquire Resource Block (RB) utilization rate and auxiliary positioning measurement report (Assisted Global Positioning System, AGPS MR) of N cells of a base station, then determine an area corresponding to overlapping sampling points of the N cells according to the AGPS MR, then calculate N target values according to RB and AGPS MR of the N cells in a first preset time period when the user equipment is in the area, and finally switch the user equipment to a second cell with the minimum target value in the N cells. Because the obtained resource RB utilization rate and the auxiliary positioning measurement report AGPS MR can influence the network performance of the cell, the integrity of data is ensured; and the calculated target value can represent the overall network performance intensity of the cell, so that the user equipment is switched to the second cell with the minimum target value, the user equipment can be accessed to the cell with stronger comprehensive network performance, the network problem of the overlapped coverage area is solved in time, and the overall processing efficiency is improved.

As shown in fig. 1, a flowchart of an overlapping coverage processing method according to an embodiment of the present application includes the following steps S101 to S104:

s101, acquiring network history data of N cells of a base station.

Wherein N is an integer greater than 1.

In the embodiment of the present application, the base station may be a fourth Generation mobile communication (Fourth Generation, 4G) base station or a Fifth Generation mobile communication (5G) base station.

In the embodiment of the application, one cell corresponds to one network history data, and the network history data corresponding to different cells are different.

In the embodiment of the present application, the network history data includes resource RB utilization and assisted positioning measurement report AGPS MR.

Illustratively, the above-described RB is a resource used by the 4G base station or the 5G base station to transmit data. The larger the bandwidth of the cell, the greater the number of RBs of the cell.

It should be noted that, RB utilization=the number of RBs actually used by the cell/the total number of RBs in the cell, when the RB utilization reaches 100%, it indicates that all RBs are fully utilized, and no more resources are available in the cell.

In an example, the MR is measurement data that all user equipments of the cell require to report periodically, and one user equipment is a sampling point, where each sampling point includes complete MR data, and includes information such as a Timing Advance (TA), a reference signal received power (Reference Signal Receiving Power, RSRP) of a serving cell, a reference signal received quality (Reference Signal Received Quality, RSRQ), neighbor information, and neighbor signal strength.

It should be noted that, the RSRP refers to signal strength, and is used to measure the quality of a cell signal.

The RSRP refers to, for example, the average value of all received Signal powers on all Resource Elements (REs) used for carrying a cell-specific Reference Signal (cell-specific Reference Signal) within a received identifier of a Reference Signal (RS) within a bandwidth used by a cell measured by a user equipment, which represents the Signal power of the cell.

Illustratively, the RSRQ described above may reflect and indicate the signal-to-noise ratio and interference level of the current channel quality. RSRQ is the change of network load and interference, and the larger the network load, i.e. the larger the load on the RE transmitting service data, the larger the interference, the smaller the RSRQ measurement value.

Illustratively, the above MR contains data as shown in table 1 below, and it should be noted that only a part of the data in the MR is shown in table 1. In practical applications, further data may be included, and will not be described here.

TABLE 1

Wherein TDD in table 1 is time division duplex (Time Division Duplexing, TDD), and FDD is frequency division duplex (Frequency Division Duplexing, FDD), MRS, MRO, MRE each represent a measurement report sample data file.

In addition, the AGPS MR according to the embodiment of the present application reports one more data, i.e. the longitude and latitude of the location of the ue, in addition to the basic MR data.

S102, according to AGPS MR, determining the overlapping coverage areas of N cells.

In the embodiment of the present application, the overlapping coverage area is an area corresponding to the overlapping sampling points of the N cells.

It should be noted that one cell corresponds to at least one sampling point.

In the embodiment of the application, a region is generally covered by a cell, and only a few regions between cells are covered by a plurality of signals.

Illustratively, as shown in fig. 2, the above-mentioned N cells include a cell a, a cell B, and a cell C. The area 4 has signals of 3 cells, namely, cell a, cell B, and cell C, and the areas 1, 2, and 3 have signals of 2 cells, respectively. If the signal strengths of the plurality of cells in the area 1, the area 2, the area 3 and the area 4 are not greatly different, the network speed of the terminal in the areas is reduced, and the area 1, the area 2, the area 3 and the area 4 are overlapping coverage areas of the N cells.

If the areas 1, 2, 3, and 4 are reasonable in range, and only one dominant signal is present in these areas, the other signals are weak, and there is no overlapping coverage area.

In the embodiment of the present application, the coverage area of each cell may be determined according to the location information of each cell in the AGPS MR, and then, according to the signal strength of the overlapping portion of the coverage area, it is determined whether the overlapping portion is overlapping the coverage area.

And S103, under the condition that the user equipment is in an overlapped coverage area, calculating N target values according to the RBs and AGPS MRs of N cells in a first preset time period.

In the embodiment of the present application, the first preset time period may be a manually set time period, and may be flexibly adjusted according to an actual scene. For example, the first preset time period is 10 minutes elapsed.

In the embodiment of the present application, the target value is used to indicate the network performance strength of the cell.

Illustratively, one cell corresponds to one target value.

For example, when determining that the location of the user equipment is within the above coverage area, RB and AGPS MR of the cell corresponding to the coverage area may be acquired within the past 10 minutes, and then the target value of each cell may be calculated from the acquired data.

S104, switching the user equipment to a second cell with the smallest target value in the N cells.

In the embodiment of the application, the smaller the target value of the cell is, the stronger the network performance of the representative cell is.

Alternatively, in the embodiment of the present application, as shown in fig. 3, the step S104 may include the following steps S104a and S104b:

and S104a, determining a second cell with the smallest target value from the N cells according to the N target values.

In the embodiment of the application, after the target value of each cell is calculated, the target value of each cell can be compared first, and the cell with the minimum target value is used as the second cell.

And S104b, switching the user equipment to the second cell.

In the embodiment of the application, after the second cell is determined, when the second cell receives the connection request sent by the user equipment, the user equipment is switched to the second cell.

In this way, since the target value is used to indicate the network performance intensity of the cell, and the smaller the target value is, the stronger the network performance is, so that the user equipment is switched to the second cell with the smallest target value, and the network performance used by the user equipment can be improved.

In the overlapping coverage processing method provided by the embodiment of the application, the resource RB utilization rate of the N cells of the base station and the assisted positioning measurement report AGPS MR can be acquired first, then the region corresponding to the coincident sampling points of the N cells is determined according to the AGPS MR, then N target values are calculated according to the RBs and AGPS MR of the N cells in the first preset time period when the user equipment is in the region, and finally the user equipment is switched to the second cell with the minimum target value in the N cells. Because the obtained resource RB utilization rate and the auxiliary positioning measurement report AGPS MR can influence the network performance of the cell, the integrity of data is ensured; and the calculated target value can represent the overall network performance intensity of the cell, so that the user equipment is switched to the second cell with the minimum target value, the user equipment can be accessed to the cell with stronger comprehensive network performance, the network problem of the overlapped coverage area is solved in time, and the overall processing efficiency is improved.

Optionally, in the embodiment of the present application, the AGPS MR includes reference signal received powers RSRP of the N cells, and the step S102 may include the following step S102a:

s102a, determining coverage areas meeting a first preset condition in the coverage areas of N cells as overlapping coverage areas.

In an embodiment of the present application, the first preset condition includes the following D and E:

D. the RSRP of the serving cell is greater than a first preset threshold.

E. The number of neighbor cells whose RSRP difference from the first cell is smaller than the second preset threshold is greater than or equal to the third preset threshold.

It should be noted that, when D and E are satisfied at the same time, the first preset condition is satisfied.

In the embodiment of the present application, the serving cell is a cell to which the ue is connected in the N cells.

In the embodiment of the present application, the first cell is a cell with the largest RSRP among the N cells.

In the embodiment of the present application, the neighbor cell is a cell other than the serving cell and the first cell among the N cells.

In the embodiment of the present application, the first preset threshold, the second preset threshold, and the third preset threshold may be manually set values, and may be flexibly set according to an actual scene. For example, the first preset threshold is-110 db (decibel relative to one milliwatt, dBm); the second preset threshold value is 3dB; the third preset threshold is 2.

In the embodiment of the application, whether the sampling points of the cells overlap the coverage sampling points can be determined according to the signal strength information of the serving cell RSRP and the plurality of neighbor cells in the AGPS MR.

Illustratively, the first preset threshold is-110 dBm, the second preset threshold is 3dB, and the third preset threshold is 2. On the premise that the RSRP of the serving cell is stronger than-110 dBm, if the number of adjacent cells with the RSRP difference value smaller than 3dB with the strongest current RSRP is more than or equal to 2, the sampling point of the serving cell is overlapped with the coverage sampling point. I.e. the serving cell and the neighbor cell both belong to cells involved in the overlapping coverage area.

In this way, when determining whether the coverage of a cell includes an overlapping coverage area, the accuracy of determining the overlapping coverage area is improved by calculating the RSRP of each cell.

Optionally, in the embodiment of the present application, in combination with the step S102a, the AGPS MR further includes location information of sampling points of the N cells, and before the step S103, the overlapping coverage processing method provided in the embodiment of the present application may further include the following step S102b:

s102b, determining that the user equipment is in the overlapping coverage area under the condition that the position information of the user equipment and the position information of the coincident sampling points meet a second preset condition.

In an embodiment of the present application, the second preset condition includes: and the number of coincident sampling points, in which the distance between the coincident sampling points and the user equipment in the second preset time period is smaller than a fourth preset threshold value, is larger than a fifth preset threshold value.

In the embodiment of the present application, the second preset time period may be a manually set time period, and may be flexibly adjusted according to an actual scene. For example, the second preset time period is the past 3 days.

For example, the location information of the user equipment and the location information of the coincident sampling point may be obtained from the AGPS MR.

The above-mentioned location information may be longitude and latitude, for example.

In the embodiment of the present application, the fourth preset threshold and the fifth preset threshold may be manually set values, and may be flexibly set according to an actual scene. For example, the fourth preset threshold is 10 meters; the fifth preset threshold is 1000.

Illustratively, taking the second preset time period as the last 3 days, the fourth preset threshold value as 10 meters, and the fifth preset threshold value as 1000 as an example. The longitude and latitude of the user equipment and the longitude and latitude of the overlapped sampling points can be obtained according to AGPS MR data in the past three days, and then the distance between the user equipment and the overlapped sampling points is calculated according to the longitude and latitude. When the distance from the user equipment to the overlapping coverage sampling points is within 10 meters and the above overlapping coverage sampling points exceed 1000, the situation is continued for a period of time T ₀ (e.g., 5 minutes), the user equipment is considered to be in an overlapping coverage area.

Therefore, the longitude and latitude of the user equipment and each sampling point are obtained through AGPS MR, the distance between the user equipment and the sampling points can be accurately calculated, and the judgment accuracy is improved.

Optionally, in the embodiment of the present application, in combination with the step 102b, the AGPS MR further includes reference signal received qualities RSRQ of the N cells, as shown in fig. 4, and the step 103 "calculating N target values according to RBs and AGPS MRs of the N cells in the first preset time period" may include the following steps S103a to S103c:

s103a, determining a target sampling point with the distance between the target sampling point and the user equipment being smaller than or equal to a sixth preset threshold value from sampling points of N cells in a first preset time period.

In the embodiment of the present application, the ue is in a radio resource control (Radio Resource Control, RRC) connected state.

Illustratively, the RRC connection state described above is used to indicate that the user equipment is in use.

In the embodiment of the present application, the sixth preset threshold may be a manually set value, and may be flexibly set according to an actual scene. For example, the sixth preset threshold is 2 meters.

Example 1, in which the first preset time period is 10 minutes, the N cells are 3 cells, and the sixth preset threshold is 2 meters is an example. AGPS MR data of the 3 cells within 10 minutes can be acquired, and then all sampling points (i.e., the target sampling points) within 2 meters from the ue are screened out according to the longitude and latitude in the AGPS MR data.

S103b, respectively calculating the RSRP average value and the RSRQ average value of each of the N cells according to the RSRP and the RSRQ of the target sampling point.

In the embodiment of the present application, the one cell corresponds to one RSRP average and one RSRQ average.

In example 2, in combination with example 1, after the target sampling points are determined, RSRP and RSRQ of the target sampling points in each cell may be screened from AGPS MR data of the 3 cells, and then RSRP average and RSRQ average of all the target sampling points in each cell may be calculated respectively.

And S103c, calculating N target values according to the RB, the RSRP average value and the RSRQ average value of each cell.

In the embodiment of the present application, the RB may be a load index of the cell in the first preset period.

Illustratively, the load index of the cell is L _i The average value of the RSRP of the cells is RSRP _i The average value of the RSRQ of the cells is RSRQ _i For example, the target value W _i Can be calculated according to formula (1), formula (1) is as follows:

W _i ＝L _i *RSRP _i *RSRQ _i formula (1)

Where i is the number of the cell.

The above L _i Is positive, L _i The smaller the cell load is, the smaller the user experience is; the RSRP described above _i And the RSRQ described above _i All have negative values, the RSRP _i The larger the cell, the better the signal of the cell; similarly, the RSRQ _i The larger the cell the better the signal. Thus, the above W _i Is positive, W _i The smaller the cell network performance the better.

Therefore, the RB, RSRP, RSRQ can reflect the network quality of the cell, so that the overall performance of the cell can be accurately and comprehensively expressed according to the target value calculated by RB, RSRP, RSRQ, the user equipment is switched to the cell with better overall performance, and the network experience of the user equipment is improved.

Further alternatively, in the embodiment of the present application, the above steps S103a to S103c may be illustrated by the following examples:

example 3 uses the ue as terminal k, and the N cells include cell a, cell B, and cell C as examples. If the terminal k is in the overlapping coverage area of the cell a, the cell B and the cell C, the terminal k receives signals with little difference in the 3 signal strengths of the 3 cells.

It is assumed that the user initially accesses the cell A, and at this time, the load index L of the cell i (i is 1, 2, 3) related to the overlapping coverage area for 10 minutes in the past is acquired first _i And acquires the RSRP of the cell i currently measured by the terminal k _i Average and RSRQ _i Average value then according to L _i 、RSRP _i 、RSRQ _i Calculating to obtain a target value W _i 。

The RSRP is as described above _i The average value is calculated as follows: acquiring AGPS MR data of the 3 cells for 10 minutes, screening RSRP data of all sampling points within 2 meters of the distance from the terminal k from the AGPS MR data, and calculating RSRP _i Average value. Similarly, the RSRQ _i The average value is calculated as follows: acquiring AGPS MR data of the 3 cells for 10 minutes, screening RSRQ data of all sampling points within 2 meters of the distance from the terminal k from the AGPS MR data, and calculating RSRQ _i Average value.

In the embodiment of the present application, if the user initially accesses the cell B or the cell C, the calculation method may be the calculation method according to the above example 3.
