Description

Method and device for checking rationality of serving cell coverage direction

technical field

The invention relates to the field of communication technology, in particular to a method and device for checking the rationality of the coverage direction of a serving cell.

Background technique

The mobile communication system is a communication system composed of cellular structure cell coverage. Ideally, each base station is divided into three sectors, and each sector covers a certain area. For example, in the case of three sectors, each sector covers a range of 120 degrees. In this way, the three sectors complete the comprehensive coverage of 360 degrees around.

In this way, the angle between the antennas of the three sectors should be 120 degrees. However, affected by factors such as user distribution, geographical environment, building group pattern, and coordination with surrounding base station cells, the three sectors of the same base station During the planning process of each sector, the included angle of the antennas between the three sectors may not be 120 degrees.

Considering the influence of factors such as interference and capacity, the angle between the antennas of two adjacent sectors should not be designed too small. For example, if the angle between the antennas of two adjacent sectors is too small, the two The coverage overlapping area of the high-intensity signals of each sector is larger, and the coverage overlapping area is mainly completed by the side lobes of the antennas of the two adjacent sectors. Generally speaking, the energy radiated by the antenna is mainly concentrated in the direction of the main lobe. The main lobe angle is conventionally defined as the angle corresponding to the lobe at which the antenna energy is attenuated by 3dB. The two sides next to the main lobe coverage are called side lobes. The radiation energy in the direction of the main lobe is the largest, and the penetration ability to buildings is the best. An antenna with excellent performance needs to effectively suppress the energy of the side lobes. Therefore, the energy of the side lobes is limited and the penetration ability is not good. Moreover, the interference of the overlapping areas of the two side lobes is relatively strong.

In this case, if the coverage overlapping area just corresponds to a densely distributed area of users and densely populated buildings, it may cause a problem of weak signal strength and large interference for a large number of users.

However, due to actual installation problems, some of the existing base stations have the phenomenon that two adjacent sectors use angled areas to cover densely built areas, resulting in unreasonable coverage of the serving cells corresponding to the sectors. However, in the prior art, there is no accurate evaluation solution for whether the coverage of each cell is reasonable.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

In conjunction with Fig. 1, the coverage of a cell with a cellular structure is exemplarily described. The base station is deployed in the center of a regular hexagon. The base station has three antennas, and the angle between each antenna is 120 degrees. Correspondingly, Each antenna covers a 120-degree sector. In this way, the three sectors composed of three antennas complete the full coverage of 360 degrees around. Each sector can be logically divided into one or Multiple cells, each sector corresponds to a cell at the same frequency point.

However, in an actual situation, the deployment of the three antennas of a base station may not be completely at a 120-degree angle between each other. In the existing antenna deployment, the angle between the two antennas of some base stations may be less than 120 degrees. In conjunction with Figure 2, the coverage of another cellular structure cell is exemplarily described. In Figure 2, the base station is deployed at the center of a regular hexagon, and the base station has three antennas, where the clip between antenna 1 and antenna 2 angle is 80 degrees, and the angle between antenna 1 and antenna 3 is 100 degrees. In this way, the angle between the serving cell corresponding to the first sector and the serving cell corresponding to the second sector is relatively large. This overlapping area It may be called the first overlapping area, and the angle between the serving cell corresponding to the first sector and the serving cell corresponding to the third sector is relatively small, and this overlapping area may be called the second overlapping area.

The first overlapping area is at the position of the side lobe of antenna 1 and antenna 2 and the back lobe of antenna 3, and the second overlapping area is at the position of the side lobe of antenna 1 and antenna 3 and the back lobe of antenna 2, which is easy to produce The signal strength is weak and the interference is strong. If the coverage of the first overlapping area and the second overlapping area is too large, or if the first overlapping area and the second overlapping area are facing an area where users and buildings are relatively dense, it may cause a large number of The signal of the mobile terminal of the user is poor. In this case, it is necessary to adjust the coverage direction of the serving cell corresponding to the corresponding sector.

For example, if the first overlapping area is facing a dense user area, causing a large number of users to receive poor signals, the coverage directions of the serving cell corresponding to the first sector and the serving cell corresponding to the second sector are different. Reasonable, needs to be adjusted.

It should be noted that a sector is a physical concept, and a cell is a logical concept, and the concepts of a sector and a cell are common knowledge of those skilled in the art.

Specifically, an embodiment of the present invention provides a method for checking the rationality of the coverage direction of a serving cell. Referring to FIG. 3 , the method includes:

301. Acquire a measurement report MR reported by the terminal, where the MR includes the identity of the primary serving cell of the terminal, the signal strength information of the primary serving cell, the identity of other cells, and the signal strength information of the other cells.

Wherein, the terminal periodically or aperiodically measures the cells in which the terminal can detect signals, and the cells in which the terminal can detect signals include the main serving cell of the terminal and other cells. Then, the terminal forms an MR to report the detected measurement results of each cell to the equipment on the access network side, such as base station, RNC and other equipment.

Wherein, the MR includes the identifier of the primary serving cell of the terminal and the signal strength information of the primary serving cell, the identifier of the other cell and the signal strength information of the other cell.

The signal strength information of the main serving cell and the signal strength information of other cells may specifically be the signal level strength or the proportion of useful signals.

For example, if the primary serving cell and other cells in the MR are cells of a WCDMA communication system, the signal strength information is: received signal code power RSCP, signal-to-interference ratio Ec/Io, signal-to-noise ratio Ec/Io No;

If the other cells in the MR are cells of the GSM communication system, the signal strength information may be: level strength Rex level, signal-to-interference ratio C/I, etc.;

If the other cell in the MR is a cell of the LTE communication system, the signal strength information may be: cell-specific reference signal strength RSRP, signal-to-noise ratio RSRQ, signal-to-interference-noise ratio SINR, and the like.

Referring to Figure 2, for a mobile terminal that uses the serving cell corresponding to the first sector as the primary serving cell, the signals that it can detect include not only the signal of the serving cell corresponding to the first sector, but may also include signals from the second sector Signals of serving cells corresponding to the third sector, and signals of serving cells of some other base stations.

Moreover, the antenna transmits signals in a wide range, and the antenna that transmits signals may radiate to sectors covered by other antennas in addition to the sector it covers. For example, referring to FIG. 2 , the mobile terminal in the first overlapping area may also detect the signal of the serving cell corresponding to the third sector.

Specifically, referring to FIG. 2 , the network side acquires 100 measurement reports reported by the terminal. Among the 100 MRs, the 1st to 40th MRs include the identifier of the primary serving cell as the identifier of the serving cell corresponding to the first sector, the strength information of the primary serving cell, and the identifiers and information of other cells. The signal strength information of the other cell, wherein the other cell is the same base station or a different base station from the main serving cell;

The identity of the primary serving cell included in the 41st-70th MRs is the identity of the serving cell corresponding to the second sector and the strength information of the primary serving cell, as well as the identity of other cells and the signal strength information of the other cells , wherein the other cell is the same base station or a different base station from the main serving cell;

The 71st to 90th MRs include the identity of the primary serving cell as the identity of the serving cell corresponding to the third sector, as well as the identity of other cells and the signal strength information of the other cells, wherein the other cells are the same as the The main serving cell is the same base station or different base stations;

The identity of the main serving cell of the terminal in the 91st-100th MR is the identity of other base station cells.

302. Acquire a first reference sampling point number according to the primary serving cell identifier, where the first reference sampling point is an MR where the primary serving cell is a first cell.

Specifically, it may be judged whether the coverage direction of the primary serving cell and the cell with the same base station as the primary serving cell is reasonable according to the influence of the cell with the same base station as the primary serving cell on the primary serving cell.

If it is judged that the coverage direction of the primary serving cell and the cell with the same base station as the primary serving cell is unreasonable, you can adjust the coverage of the primary serving cell and the cell with the same base station as the primary serving cell Direction, to rationalize the coverage direction of the main serving cell and the cell with the same base station as the main serving cell, so as to achieve the purpose of network optimization.

For example, referring to FIG. 2 , when the cell corresponding to the first sector is used as the primary serving cell, that is, the first cell. Another cell A is a cell with the same base station as the first cell, that is, a second cell. To determine the impact of the second cell on the first cell, an MR whose primary serving cell is the first cell may be selected from the above 100 MRs as the first reference sampling point. Since among the 100 MRs, the primary serving cell in the 1st-40th MR is the cell corresponding to the first sector, that is, the first cell, at this time, the 1st-40th MR is the first reference Sampling point.

Further, when the signal strength of the primary serving cell is weak, even if the coverage direction of the primary serving cell is unreasonable, changing the coverage direction of the primary serving cell will not have great significance for network optimization. Therefore, it is also possible to only Consider using the MR whose signal strength of the primary serving cell is greater than the second preset threshold as the first reference sampling point.

For example, the primary serving cell reported by the terminal in the 1st-40th MRs among the 100 MRs is the first cell, and the signal strength of the first cell in the 1st-30th MRs is greater than that of the second cell. The preset threshold, where assuming that the second preset threshold is -50dBm, at this time, the 1st to 30th MRs are the first reference sampling points, and the number of the first reference sampling points is 30.

303. According to the signal strength information of the second cell of the same base station as the first cell, acquire the number of sampling points of coverage overlap influence degree.

When the identity of the primary serving cell in an MR is the identity of the first cell, and the other cells include cells that are in the same base station as the first cell, that is, the second cell, the coverage overlap influence degree is the The degree of influence of the second cell on the primary serving cell.

When the signal strength of the second cell satisfies a certain condition, it may be considered that the second cell has a greater influence on the primary serving cell, that is, the first cell.

For example, when the primary serving cell is the first cell and the signal strength of the second cell is greater than a first preset threshold, it may be considered that the second cell has less influence on the first cell. big.

For example, using RSCP as a basis for signal strength, when the RSCP of the second cell is greater than -75dBm, it may be considered that the second cell has a greater impact on the second cell.

At this time, the sampling point of coverage overlap influence means that the primary serving cell is the first cell, other cells include the second cell, and the signal strength of the second cell is greater than the MR of the first preset threshold.

Assuming that the MRs satisfying this condition are the 1st to 10th MRs among the 100 MRs, then the 1st to 10th MRs are the sampling points of the coverage overlap influence degree.

It should be noted that, if in the process of obtaining the first reference sampling points, the limiting condition that the signal strength of the first cell is greater than the second preset threshold is taken into account, in the process of obtaining the coverage overlap influence degree sampling points , the condition that the signal strength of the first cell is greater than the second preset threshold also needs to be taken into consideration.

For example, if the 1st to 10th MRs satisfy that the primary serving cell is the first cell, the other cells include a second cell that is the same base station as the primary serving cell, and the signal strength of the second cell is greater than that of the first cell. A preset threshold, then in the case of meeting the above conditions, the MRs that also meet the signal strength of the first cell greater than the second preset threshold are the 3rd-10th MRs, then the 3rd-10th MRs are the coverage overlap Influence sampling point.

It should be noted that there is no sequence between step 302 and step 303, that is, the acquisition of the first reference sampling points and the coverage overlapping influence degree sampling points. Specifically, taking the case where the signal strength of the first cell is not considered to be greater than the second preset threshold as an example, the following method may be adopted:

Method 1: first obtain the number of first reference sampling points, and then obtain from all the first reference sampling points the second cell that includes the same base station as the first cell in other cells, and the signal strength of the second cell is greater than that of the first cell. The MR of the preset threshold is used as the number of sampling points for coverage overlap influence degree.

Mode 2: firstly acquire MRs whose signal strength of the second cell is greater than the first preset threshold from all MRs, and then select from all MRs whose signal strength of the second cell is greater than the first preset threshold The first cell serves as the primary serving cell, and includes the MR identified by the second cell as the number of sampling points of coverage overlap influence degree. From all MRs, an MR that satisfies the need to include the first cell as the primary serving cell is selected as the number of first reference sampling points.

Mode 3: Select an MR from all MRs that simultaneously includes the first cell as the primary serving cell, and includes the identity of the second cell, and the signal strength of the second cell is greater than the first preset threshold as the coverage overlap impact The number of sampling points. From all MRs, an MR that satisfies the need to include the first cell as the primary serving cell is selected as the number of first reference sampling points.

It should be noted that any method for obtaining the first reference sampling points and the sampling points of coverage overlap influence degree that can be easily obtained by those skilled in the art based on the idea of the present invention is within the protection scope of the present invention.

304. Determine whether the coverage directions of the first cell and the second cell are reasonable according to a ratio of the number of sampling points of coverage overlap influence degree to the number of first reference sampling points.

After the first reference number of sampling points and the number of sampling points of the degree of coverage overlap influence are acquired, a ratio of the number of sampling points of the degree of coverage overlap influence to the first reference number of sampling points is obtained.

For example, in the 1st to 40th MRs among the 100 MRs, the first cell is used as the main serving cell, then the first reference sampling points are the 1st to 40th MRs, and the first reference sampling points are The number is 40;

The first cell in the 1st-10th MR is used as the primary serving cell, and the other cells include a second cell that is the same base station as the first cell, and the signal strength information of the second cell is greater than the first preset threshold, then The number of sampling points for coverage overlap influence degree is 1-10 MRs, and the number of sampling points for coverage overlap influence degree is 10.

At this time, the ratio of the number of sampling points of the coverage overlap influence degree to the number of the first reference sampling points is 1/4, which can be considered as the coverage overlap influence degree coefficient of the second cell to the first cell, and the network optimization personnel can According to this ratio, it is judged whether the impact of the second cell on the first cell is serious, and then it is judged that the coverage overlapping area of the first cell and the second cell is facing a dense user area, based on this , judging whether the coverage directions of the first cell and the second cell need to be adjusted.

It should be noted that the greater the coverage overlap influence coefficient of the second cell on the first cell, the greater the impact of the second cell on the first cell, and the first cell and the first cell The more serious the coverage overlap problem of the second cell is, that is, the greater the possibility is that the coverage overlap area of the first cell and the second cell corresponds to a denser area of users or building groups.

Further, by adopting the above solution, the coverage overlap influence degree coefficients between two cells of each base station can be obtained.

Suppose base station 1 has three cells, namely cell A1, cell B1 and cell C1;

Base station 2 has three cells, namely cell A2, cell B2 and cell C2;

Base station 3 has three cells, namely cell A3, cell B3 and cell C3;

When A1 is used as the main serving cell, the coverage overlap influence coefficients of B1 and C1 on A1 are 1/4 and 1/5 respectively;

When A2 is used as the main serving cell, the coverage overlap influence coefficients of B2 and C2 on A2 are 1/6 and 1/5 respectively;

When A3 is used as the main serving cell, the coverage overlap influence coefficients of B3 and C3 on A3 are 1/7 and 1/10 respectively;

From this, it can be judged that cell B1, which is the same base station as the primary serving cell A1, has the largest coefficient of coverage overlap influence on cell A1, indicating that the problem of coverage overlap between cell A1 and cell B1 is serious, and the coverage overlap area of said A1 and said B1 It is more likely to correspond to an area with relatively dense users and building groups, and the coverage directions of the cell A1 and the cell B1 need to be adjusted.

An embodiment of the present invention provides a method for judging the rationality of the coverage direction of a serving cell. The method includes: obtaining a measurement report MR reported by a terminal, the MR including the primary serving cell identifier of the terminal and the primary serving cell The signal strength information of other cells, the identification of other cells, and the signal strength information of the other cells; according to the identity of the primary serving cell, the number of first reference sampling points is obtained, and the first reference sampling point is that the primary serving cell is the first The MR of the cell; according to the signal strength information of the second cell of the same base station as the first cell, obtain the number of sampling points of coverage overlap influence; according to the ratio of the number of sampling points of coverage overlap influence to the first reference sampling point, Judging whether the coverage directions of the first cell and the second cell are reasonable. According to the method, the measurement report reported by the mobile terminal and the signal strength of a cell of the same base station as the primary serving cell are used to analyze the degree of influence of the coverage overlap of the primary serving cell by the cell of the same base station as the primary serving cell. Based on this method, Whether the coverage directions of the main serving cell and the cells of the same base station as the main serving cell are reasonable can be quickly and accurately judged.

The embodiment of the present invention provides a method for judging the rationality of the coverage direction of the serving cell. Referring to FIG. 4, the method includes:

401. Acquire a measurement report MR reported by the terminal, where the MR includes the identity of the primary serving cell of the terminal, the signal strength information of the primary serving cell, the identity of other cells, and the signal strength information of the other cells.

402. Acquire a first reference sampling point number according to the primary serving cell identifier, where the first reference sampling point is an MR where the primary serving cell is a first cell.

Specifically, for the detailed implementation process of step 401-step 402, reference may be made to step 301-step 302 in the foregoing embodiment, which will not be repeated in the implementation of the present invention.

403. Obtain that the primary serving cell is the first cell, the other cells include a second cell that is the same base station as the first cell, and the signal strength information of the first cell is the same as the signal strength information of the second cell The MR whose difference value is within the first preset range is used as the sampling point of coverage overlap influence degree.

Specifically, it is judged by whether the difference between the signal strength of the primary serving cell, that is, the first cell, and the cell of the same base station as the primary serving cell, that is, the signal strength of the second cell, is within the first preset range. The degree of influence of the second cell on the first cell.

If the difference between the signal strength of the first cell and the signal strength of the second cell is within a first preset range, it is determined that the degree of influence of the second cell on the first cell is relatively large; if the The difference between the signal strength of the first cell and the signal strength of the second cell is not within a first preset range, and it is determined that the degree of influence of the second cell on the first cell is small.

For example, using RSCP as the basis for signal strength, if the difference between the RSCP of the first cell and the RSCP of the second cell is less than 3dBm, it is considered that the influence of the second cell on the first cell is relatively small. big. Of course, if the signal strength of the second cell is greater than the signal strength of the first cell, the difference between the signal strengths of the first cell and the second cell is negative, and the condition that the difference is less than 3dBm is also satisfied .

Assume that among the 100 MRs, at the same time, the identity of the primary serving cell is the first cell, and the identity of the cell that is the same base station as the primary serving cell, that is, the identity of the second cell, and the identity of the first cell The MR whose difference between the signal strength information and the signal strength information of the second cell is within the first preset range is the 3rd-14th MR, then the 3rd-14th MR is the coverage overlap influence degree Sampling points, the number of sampling points for coverage overlap influence degree is 12.

Specifically, there is no sequence between step 402 and step 403, and the first reference sampling points may be obtained first, or the sampling points of coverage overlap influence degree may be obtained first, which is not limited in this embodiment of the present invention.

404. Determine whether the coverage directions of the first cell and the second cell are reasonable according to the ratio of the sampling points of the coverage overlap influence degree to the first reference sampling points.

Specifically, for the detailed implementation process of step 404, reference may be made to step 304 in the foregoing embodiment, which will not be repeated in this embodiment of the present invention.

The embodiment of the present invention provides a method for judging the rationality of the coverage direction of the serving cell. The method judges the signal strength of the primary serving cell and a cell of the same base station as the primary serving cell through the measurement report reported by the mobile terminal. Whether the difference is within the first preset range, and the degree of influence of the coverage overlap of the primary serving cell by the cell of the same base station as the primary serving cell is analyzed. Based on this method, it is possible to quickly and accurately judge the Whether the coverage direction of the primary serving cell and the cell area of the same base station as the primary serving cell is reasonable.

The embodiment of the present invention provides a method for judging the rationality of the coverage direction of the serving cell. Referring to FIG. 5, the method includes:

501. Obtain a measurement report MR reported by the terminal, where the MR includes the identity of the primary serving cell of the terminal, the signal strength information of the primary serving cell, the identity of other cells, and the signal strength information of the other cells.

502. Acquire a first reference sampling point number according to the primary serving cell identifier, where the first reference sampling point is an MR where the primary serving cell is a first cell.

Specifically, for the detailed implementation process of step 501-step 502, reference may be made to step 301-step 302 in the foregoing embodiment, which will not be repeated in this embodiment of the present invention.

503. Obtain that the primary serving cell is the first cell, the other cells include a second cell that is the same base station as the first cell, and the difference between the signal strength information of the third cell and the signal strength information of the second cell An MR whose value is within the second preset range is used as a sampling point of coverage overlap influence, wherein the third cell is the primary serving cell and the first cell, and the other cells include A cell with the largest signal strength information in each MR of the second cell of the base station.

Specifically, the cell with the strongest signal strength in the MR containing the identity of the primary serving cell as the first cell and the identity of the cell with the same base station as the first cell, that is, the identity of the second cell, is Whether the signal strength of the third cell and the difference between the signal strength of the second cell and the signal strength of the second cell are within a second preset range is used to determine the degree of influence of the second cell on the first cell.

Specifically, the third cell is the cell with the strongest signal strength in the MR, which may be the first cell or the second cell, or may be another cell in the same base station as the first cell or in the same base station as the first cell. The first cell is different from other cells of the base station.

In the technical solution provided by step 403 in the above embodiment, the difference between the first cell and the second cell may be a negative value, that is, the signal strength of the second cell may be greater than the signal strength of the first cell . However, in the embodiment of the present invention, since the third cell is the cell with the strongest signal in the MR, the difference between the signal strengths of the third cell and the second cell will not have a negative value.

If the difference between the signal strength of the third cell and the signal strength of the second cell is within a second preset range, it is determined that the degree of influence of the second cell on the first cell is relatively large; if the The difference between the signal strength of the third cell and the signal strength of the second cell is not within a first preset range, and it is determined that the degree of influence of the second cell on the first cell is small.

For example, using RSCP as the basis for signal strength, if the difference between the RSCP of the third cell and the RSCP of the second cell is less than 3dBm, it is considered that the influence of the second cell on the first cell is relatively small. big. Of course, when the cell with the strongest signal is the second cell, the difference between the signal strengths of the third cell and the second cell is 0, which is also within the second preset range.

Assume that among the 100 MRs, at the same time, the identification of the primary serving cell as the first cell is satisfied, and the identification of the cell with the same base station as the primary serving cell, that is, the identification of the second cell, and the identification of the third cell The MR whose difference between the signal strength information and the signal strength information of the second cell is within the first preset range is the 3rd-12th MR, then the 3rd-12th MR is the coverage overlap influence degree Sampling points, the number of sampling points for coverage overlap influence degree is 10.

Specifically, there is no sequence between step 402 and step 403, and the first reference sampling points may be obtained first, or the sampling points of coverage overlap influence degree may be obtained first, which is not limited in this embodiment of the present invention.

504. Determine whether the coverage directions of the first cell and the second cell are reasonable according to a ratio of the number of sampling points of coverage overlap influence degree to the number of first reference sampling points.
