A comprehensive and reasonable configuration of neighboring cells can maximize network performance and enhance user experience. Use perception. However, the current configuration of adjacent cells is mostly through software simulation and manual adjustment, so there will be omissions and redundancy in the configuration of adjacent cells. Therefore, checking the omissions and redundancy in the configuration of adjacent cells has become the current technology development trend. At present, there are mainly two methods for checking the configuration of adjacent cells: the first method is based on the drive test results to find the call drops caused by the missing configuration of adjacent cells, and to detect the phenomenon of missing configuration of adjacent cells, redundancy, etc.; The second is to use the distance of the adjacent cell to judge and detect the wrong configuration of adjacent cells such as missing configuration and redundancy.

The first method consumes too much manpower and material resources, and requires road testing of the entire network. Areas such as residential areas, streets, and scenic spots cannot be tested, and the testing scope is limited by geography. The second method must test all the cells, and the calculation process is time-consuming. At the same time, the current WCDMA technology allows the cells to be farther away. If the distance judgment is used completely, it will fail in many remote coverage areas, and test errors will occur, misleading daily network optimization. and maintenance staff.

Therefore, how to eliminate the geographical limitation of the test range in the neighboring cell configuration verification, simplify the test to save time, and avoid the test error caused by the distance between the cells, so as to conduct the neighbor cell configuration verification comprehensively, accurately and quickly, is the current need to solve The problem.

Embodiment one

The implementation of the present invention provides a neighboring cell configuration verification method, which can be applied to the communication field and can be applied to neighboring cell configuration verification. Specifically, it can be used in conjunction with the neighboring cell configuration verification device provided in the following embodiments of the present invention, as shown in FIG. 1 , including the following steps:

101. Acquire the number of source handovers between a source cell and a target cell, and acquire an average number of handovers between cells in a communication network, where the communication network includes the source cell and the target cell.

Wherein, the source cell is a cell that needs to be checked for neighbor cell configuration, and the target cell is any one of the adjacent cells of the source cell.

The number of handovers may be the number of handover requests or the number of successful handovers. Therefore, the number of source switching times may be the number of source switching requests or the number of successful source switching; the average number of switching times may be the average number of switching requests or the average number of successful switching.

The number of source handover requests is the number of handover requests sent by the source cell to the target cell, and the number of successful source handovers is the number of successful handovers after the source cell sends handover requests to the target cell. The average number of handover requests is the average number of times that one cell in every two adjacent cells of the communication network sends a handover request to another cell, and the average number of successful handovers is the number of times that every two adjacent cells The number of successful handovers after one cell sends a handover request to another.

When the number of source switching times is the number of source switching requests, the average number of switching times is the average number of switching requests; when the number of source switching times is the number of successful source switching times, the average number of switching times is the average number of successful switching times.

Specifically, both the source handover times and the average handover times may be obtained from inter-cell handover times recorded in a database of the communication network.

102. According to the number of times of source handovers and the number of times of average handovers, check whether there is missing configuration of adjacent cells or redundancy of adjacent cells between the source cell and the target cell.

Wherein, for the source cell and the target cell, it may be checked whether there is an unreasonable configuration of adjacent cells such as missing configuration of adjacent cells or redundant adjacent cells.

Specifically, the optional implementation methods are:

Firstly, it is judged whether the number of times of source switching is greater than or smaller than a reference range of the average number of switching times, and the reference range has an upper limit of a reference range and a lower limit of a reference range. For example, the upper limit of the reference range can be set as 1.5 times of the average switching times, and the lower limit of the reference range can be set as 0.8 times of the average switching times, at this time, the reference range is the average switching times 0.8 times to 1.5 times. The purpose of setting the reference range is to reasonably evaluate the configuration status of neighboring cells between cells (for example, whether there is missing or redundant neighboring cells). The specific upper limit and lower limit of the reference range can be set according to actual needs.

Afterwards, when the number of source handovers is greater than the upper limit of the reference range of the average number of handovers (that is, when the number of source handovers is greater than the reference range), it is determined that there is a neighbor between the source cell and the target cell. Area missing. At this time, it may be necessary to add a cell between the source cell and the target cell.

Alternatively, when the number of source handovers is less than the lower limit of the reference range of the average number of handovers (that is, when the number of source handovers is less than the reference range), it may be determined that there is a neighbor between the source cell and the target cell. zone redundancy. At this time, it may be necessary to reduce the number of cells between the source cell and the target cell.

Because the inventor finds that when there is missing neighbor cell configuration between two cells, the number of cells available for handover of communication services is less than the normal demand, and the number of handovers between these two cells will be greater than the upper limit of the reference range of the average number of handovers. Conversely, if there are redundant adjacent cell configurations between the two cells, this is neighbor cell redundancy, and there are more cells available for communication service switching than normal demand, and the number of handovers between these two cells will be less than the average number of handovers. The lower limit of the reference range.

In places where the demand for communication services is high, even if the cells are densely populated, there may not necessarily be redundancy of neighboring cells. In places where the demand for communication services is small, even if the cells are sparse, there may not necessarily be missing adjacent cells. Therefore, it is necessary to carry out the above-mentioned adjacent cell configuration check according to the actual situation, so as to know the actual demand according to the adjacent cell configuration check result, adjust the cell configuration, and make full use of communication resources such as communication cells.

The neighbor cell configuration verification method provided by the embodiment of the present invention can obtain the number of source handovers between the source cell and the target cell, and obtain the average number of handovers between the cells in the communication network, the communication network includes the source cell and the target cell. The target cell; according to the source handover times and the average handover times, check whether there is missing neighbor cell configuration or neighbor cell redundancy between the source cell and the target cell. Because the verification process does not require a drive test and is not restricted by geographical conditions, it can eliminate the geographical limitations of the test range in the verification of neighboring cell configurations; and the verification is carried out by combining the handover records of each cell with the geographical location information, which can Avoid the trouble of having to detect all cells when judging only by distance, and simplify the test to save time; it can also avoid the failure of the neighboring cell configuration verification scheme that only uses distance judgment to fail in many areas with extended coverage, so it can avoid excessive distance between cells. test error, so that the neighboring cell configuration verification can be carried out comprehensively, accurately and quickly.

Embodiment two

The implementation of the present invention provides a method for checking the configuration of adjacent cells. This method can be regarded as proposed on the basis of the method for checking the configuration of adjacent cells provided in Embodiment 1. It can be applied to the field of communication and can be applied to checking the configuration of adjacent cells. Specifically It can be used in conjunction with the neighboring cell configuration checking device provided in the following embodiments of the present invention, as shown in FIG. 2 , including the following steps:

201. Acquire the number of source handovers between a source cell and a target cell, and acquire an average number of handovers between cells in a communication network, where the communication network includes the source cell and the target cell.

Wherein, the source cell is a cell that needs to be checked for neighbor cell configuration, and the target cell is any one of the adjacent cells of the source cell.

The number of handovers may be the number of handover requests or the number of successful handovers. Therefore, the number of source switching times may be the number of source switching requests or the number of successful source switching; the average number of switching times may be the average number of switching requests or the average number of successful switching.

The number of source handover requests is the number of handover requests sent by the source cell to the target cell, and the number of successful source handovers is the number of successful handovers after the source cell sends handover requests to the target cell. The average number of handover requests is the average number of times that one cell in every two adjacent cells of the communication network sends a handover request to another cell, and the average number of successful handovers is the number of times that every two adjacent cells The number of successful handovers after one cell sends a handover request to another.

When the number of source switching times is the number of source switching requests, the average number of switching times is the average number of switching requests; when the number of source switching times is the number of successful source switching times, the average number of switching times is the average number of successful switching times.

Specifically, both the source handover times and the average handover times may be obtained from inter-cell handover times recorded in a database of the communication network.

202. Acquire an inter-cell direction angle between the source cell and the target cell;

Specifically, it may be: obtaining the source latitude and longitude information of the source cell and the target latitude and longitude information of the target cell, and obtaining the direction angle of the source cell of the source cell; then, according to the source latitude and longitude information, the target latitude and longitude information and the obtained The direction angle of the source cell is calculated, and the inter-cell direction angle between the source cell and the target cell is calculated.

For example, as shown in Figure 3, the center points of the source cell and the target cell correspond to the latitude and longitude indicated by the respective latitude and longitude information, and the center point of the source cell is the starting point, along the direction of the central axis of the sector A of the source cell. The direction is the cell direction of the source cell. The direction angle corresponding to this direction ray is the direction angle β of the source cell. The direction angle β of the source cell is already set when the cell sector is configured. ) is represented by the direction angle of the cell, so obtaining the direction angle β of the source cell is equivalent to obtaining the spatial information of the ray in this direction. The line segment formed by the line connecting the center points of the source cell and the target cell is regarded as the azimuth line segment. The inter-cell direction angle α is the angle between the direction ray and the azimuth line segment.

Of course, if the inter-cell direction angle between the source cell and the target cell has been recorded during the configuration of each cell, it can be directly retrieved.

203. Determine whether the inter-cell direction angle exceeds a preset angle range.

Optionally, when the inter-cell direction angle exceeds a preset angle range, step 204 may be performed; when the inter-cell direction angle does not exceed a preset angle range, step 205 may be performed.

Specifically, as shown in FIG. 3 , the preset angle range may be set to a range of ±90°. If the direction angle α between the cells is outside the range of ±90°, it means that the two cells are facing away from the neighboring cells, then step 204 can be performed; if the direction angle α between the cells is within the range of ±90°, it means that the two cells are is a forward neighboring cell, step 205 may be performed.

204. When the direction angle between the cells exceeds the preset angle range, according to the number of source handovers and the average number of handovers, determine whether there is a missing adjacent cell or adjacent cell between the source cell and the target cell Check for redundancy.

This step can be regarded as a specific implementation of "checking whether there is missing neighbor cell configuration or neighbor cell redundancy between the source cell and the target cell according to the source handover times and the average handover times" Way.

Specifically, if the preset angle range can be set to a range of ±90°, and the inter-cell direction angle α is outside the range of ±90°, it means that the two cells face away from neighboring cells.

When the direction angle between the cells exceeds the preset angle range, it can be known by referring to step 102, according to the number of source handovers and the average number of handovers, whether there is a missing neighbor cell between the source cell and the target cell or adjacent cell redundancy check, which may specifically include:

204a. Determine whether the number of times of source switching is greater than or smaller than a reference range of the average number of times of switching.

Specifically, the reference range has an upper limit of the reference range and a lower limit of the reference range. For example, the upper limit of the reference range can be set as 1.5 times of the average switching times, and the lower limit of the reference range can be set as 0.8 times of the average switching times, at this time, the reference range is the average switching times 0.8 times to 1.5 times.

Optionally, when the number of source switching times is greater than the upper limit of the reference range of the average switching times, step 204b may be performed; when the number of source switching times is smaller than the lower limit of the reference range of the average switching times, step 204c may be performed.

204b. When the number of source handovers is greater than the upper limit of the reference range of the average number of handovers (that is, when the number of source handovers is greater than the reference range), determine that there is a neighboring cell between the source cell and the target cell Missing allocation; at this time, it may be necessary to add a cell between the source cell and the target cell.

Specifically, taking the number of handovers as the number of handover requests and the upper limit of the reference range as 1.5 times the average number of handovers as an example, if the inter-cell direction angle exceeds the preset angle range, the number of handover requests at the source is greater than the average When the number of handover requests is 1.5 times, it is determined that there is a need for cell handover between the source cell and the target cell, and there is a lack of adjacent cell configuration between the source cell and the target cell, and a cell needs to be added.

204c. When the number of source handovers is less than the lower limit of the reference range of the average number of handovers (that is, when the number of source handovers is less than the reference range), determine that there is a neighboring cell between the source cell and the target cell redundancy. At this time, it may be necessary to reduce the number of cells between the source cell and the target cell.

Specifically, taking the number of handovers as the number of handover requests and the lower limit of the reference range as 0.8 times the average number of handovers as an example, if the inter-cell direction angle exceeds the preset angle range, the number of handover requests at the source is less than the average When the number of handover requests is 0.8 times, it is determined that the demand for cell handover between the source cell and the target cell is insufficient, and the neighbor cell between the source cell and the target cell is redundant. The redundant neighbor cell can be screened out according to the actual situation and the configuration can be canceled.

Because when there is missing configuration of adjacent cells between two cells, the number of cells available for handover of communication services is less than the normal demand, and the number of handovers between these two cells will be greater than the upper limit of the reference range of the average number of handovers. Conversely, if there are redundant adjacent cell configurations between the two cells, this is the neighbor cell redundancy, and there are more cells available for communication service switching than normal demand, and the number of handovers between these two cells will be less than the reference for the average number of handovers The lower limit of the range.

205. Acquire the number of main lobe handovers between the source cell and other cells in the coverage direction of its own main lobe, and acquire the total number of handovers between the source cell and all cells, the other cells excluding the target cell .

Wherein, the source cell and the other cells are adjacent cells, and all the cells are all cells adjacent to the source cell.

Because the number of handovers may be the number of handover requests or the number of successful handovers. Therefore, the number of main lobe switching times may be the number of main lobe switching requests or the number of successful main lobe switching; the total number of switching times may be the total number of switching requests or the total number of successful switching times.

The number of main lobe handover requests is the number of times the source cell sends handover requests to the other cells; the number of successful main lobe handovers is the number of successful handovers after the source cell sends handover requests to the other cells ; The total number of handover requests is the number of times that the source cell sends handover requests to all the cells; the total number of successful handovers is the number of successful handovers after the source cell sends handover requests to all the cells;

206. Calculate a forward handover ratio of the source cell, where the forward handover ratio of the source cell is a ratio of the number of main lobe handovers to the total number of handovers.

207. Determine whether the forward switching ratio is smaller than a preset ratio.

Specifically, the preset ratio can be set according to requirements, for example, set to 50%.

Optionally, when the inter-cell direction angle does not exceed a preset angle range, and the forward switching ratio is smaller than a preset ratio, step 208 is performed.

It should be noted here that the steps 205-207 are not necessarily after the step 203, and such steps are set here only for the convenience of understanding and description.

208. When the direction angle between the cells does not exceed the preset angle range, and the proportion of the forward handover is less than a preset ratio, according to the number of source handovers and the average number of handovers, perform Check whether there is missing neighbor cell allocation or neighbor cell redundancy between the above target cells.

This step can be regarded as a specific implementation of "checking whether there is missing neighbor cell configuration or neighbor cell redundancy between the source cell and the target cell according to the source handover times and the average handover times" Way.

Specifically, if the preset angle range can be set to a range of ±90°, and the inter-cell direction angle α is within ±90°, it indicates that the two cells are forward neighboring cells.

When the inter-cell direction angle does not exceed the preset angle range, and the forward handover ratio is less than the preset ratio, referring to step 102, it can be known that according to the number of source handovers and the average number of handovers, the source Check whether there is missing neighbor cell configuration or neighbor cell redundancy between the cell and the target cell, which may specifically include:

208a. Determine whether the number of times of source switching is greater than or smaller than a reference range of the average number of times of switching.

Optionally, when the number of source switching times is greater than the upper limit of the reference range of the average switching times, step 208b may be performed; when the number of source switching times is smaller than the lower limit of the reference range of the average switching times, step 208c may be performed.

208b. When the number of source handovers is greater than the upper limit of the reference range of the average number of handovers (that is, when the number of source handovers is greater than the reference range), determine that there is a neighboring cell between the source cell and the target cell Missing allocation; at this time, it may be necessary to add a cell between the source cell and the target cell.

Specifically, taking the number of handovers as the number of handover requests, the preset ratio as 50%, and the upper limit of the reference range as 1.5 times the average number of handovers as an example, if the inter-cell direction angle does not exceed the preset Angle range, when the number of source handover requests is greater than 1.5 times the average number of handover requests, and the proportion of forward handover is less than 50%, it is determined that there is a need for handover between the source cell and the target cell. It is necessary to add a cell for the missing allocation of adjacent cells.

208c. When the number of source handovers is less than the lower limit of the reference range of the average number of handovers (that is, when the number of source handovers is less than the reference range), determine that there is a neighboring cell between the source cell and the target cell redundancy. At this time, it may be necessary to reduce the number of cells between the source cell and the target cell.

Specifically, taking the number of handovers as the number of handover requests, the preset ratio as 50%, and the lower limit of the reference range as 0.8 times the average number of handovers as an example, if the inter-cell direction angle does not exceed the preset Angle range, when the number of source handover requests is less than 0.8 times the average number of handover requests, and the proportion of forward handover is less than 50%, it is determined that the demand for handover between the source cell and the target cell is insufficient, and between the source cell and the target cell is Neighboring cell redundancy, you can filter out redundant neighboring cells and cancel the configuration according to the actual situation.

Because the inventor finds that when there is missing neighbor cell configuration between two cells, the number of cells available for handover of communication services is less than the normal demand, and the number of handovers between these two cells will be greater than the upper limit of the reference range of the average number of handovers. Conversely, if there are redundant adjacent cell configurations between the two cells, this is neighbor cell redundancy, and there are more cells available for communication service switching than normal demand, and the number of handovers between these two cells will be less than the average number of handovers. The lower limit of the reference range.

In places where the demand for communication services is high, even if the cells are densely populated, there may not necessarily be redundancy of neighboring cells. In places where the demand for communication services is small, even if the cells are sparse, there may not necessarily be missing adjacent cells. Therefore, it is necessary to carry out the above-mentioned adjacent cell configuration check according to the actual situation, so as to know the actual demand according to the adjacent cell configuration check result, adjust the cell configuration, and make full use of communication resources such as communication cells.

The neighbor cell configuration verification method provided by the embodiment of the present invention can obtain the number of source handovers between the source cell and the target cell, and obtain the average number of handovers between the cells in the communication network, the communication network includes the source cell and the target cell. The target cell; according to the source handover times and the average handover times, check whether there is missing neighbor cell configuration or neighbor cell redundancy between the source cell and the target cell. Because the verification process does not require a drive test and is not restricted by geographical conditions, it can eliminate the geographical limitations of the test range in the verification of neighboring cell configurations; and the verification is carried out by combining the handover records of each cell with the geographical location information, which can Avoid the trouble of having to detect all cells when judging only by distance, and simplify the test to save time; it can also avoid the failure of the neighboring cell configuration verification scheme that only uses distance judgment to fail in many areas with extended coverage, so it can avoid excessive distance between cells. test error, so that the neighboring cell configuration verification can be carried out comprehensively, accurately and quickly. In addition, according to whether the direction angle between the cells exceeds the preset angle range, different neighbor cell configuration checks can be carried out for the forward neighbor cell and the back face neighbor cell, which avoids not distinguishing between the forward neighbor cell and the backward neighbor cell in the current prior art. The verification result caused by facing away from the adjacent area is inaccurate. The accuracy of neighbor cell configuration verification is further improved.
