It should be noted that the above-mentioned application scenarios are only presented for the convenience of understanding the spirit and principles of the present application, and the embodiments of the present application are not limited in this respect. Rather, the embodiments of the present application may be applied to any applicable scenario.
The following describes a load identification method of a wireless network according to an embodiment of the present application with reference to application scenarios shown in fig. 1A and fig. 1B.
As shown in fig. 2, an embodiment of the present application provides a load identification method for a wireless network, where the method may be applied to a load identification device for a wireless network, and the method includes:
step 201: and determining the first cell and the second cell as the same coverage cell.
As can be seen from the foregoing description, the co-coverage cells are two cells whose coverage areas of the wireless network signals satisfy the predetermined condition.
It should be noted that there are multiple determination manners for the same coverage cell, for example, the determination manner for the same coverage cell in the same site may be different from the determination manner for the same coverage cell in different sites. The determination method of the co-coverage cell may include, but is not limited to, the following methods:
in embodiment 1, if the first cell and the second cell are located at the same site, the process of determining that the first cell and the second cell are located in the same coverage cell may be: and determining that the difference value between the azimuth angle corresponding to the coverage range of the first cell and the azimuth angle corresponding to the coverage range of the second cell is smaller than a first preset value, and determining that the first cell and the second cell are the same coverage cell.
For example, please refer to fig. 1A again, the first cell takes cell 1 of base station a as an example, the second cell takes cell 4 of base station B as an example, the first preset value takes β as an example, the azimuth angle of the coverage range of cell 1 is ≧ a1, the azimuth angle of the coverage range of cell 4 is × B1, and the difference | < a 1-B1 | < β between the azimuth angles of cell 1 and cell 4, then cell 1 and cell 4 are the same coverage cell.
Similarly, please continue to refer to fig. 1A, the first cell takes cell 3 of base station a as an example, the second cell takes cell 6 of base station B as an example, the first preset value takes β as an example, the azimuth angle of the coverage range of cell 3 is ≥ A3, the azimuth angle of the coverage range of cell 6 is ≥ B3, and the difference ≤ A3- ≥ B3 ≥ β between the azimuth angles of cell 3 and cell 6, then cell 3 and cell 6 are not the same coverage cell.
Similarly, please continue to refer to fig. 1A, the first cell takes cell 1 of base station a as an example, the second cell takes cell 5 of base station B as an example, the first preset value takes β as an example, the azimuth angle of the coverage range of cell 1 is ≥ a1, the azimuth angle of the coverage range of cell 5 is ≥ B2, and the difference value ≤ a1- ≥ B2 ≥ β between the azimuth angles of cell 1 and cell 5, then cell 1 and cell 5 are not the same coverage cell.
In embodiment 2, if the first cell and the second cell have different station addresses, the process of determining that the first cell and the second cell are the same coverage cell may be: determining a connection line between a base station where a first cell is located and a base station where a second cell is located; determining a first included angle between an azimuth angle corresponding to the coverage range of the first cell and the connection line and a second included angle between the azimuth angle corresponding to the coverage range of the second cell and the connection line; and if the sum of the first included angle and the second included angle is smaller than a second preset value, determining that the first cell and the second cell are the same coverage cell.
For example, please refer to fig. 1B, the first cell is a cell 2 of the base station a, the second cell is a cell 5 of the base station B, and the second preset value is a cell 2 of the base station a
For example, the connection line between the base station a and the base station B is d. A first included angle between the azimuth angle of the coverage range of the cell 2 and the connecting line d is ^ A2, a second included angle between the azimuth angle of the coverage range of the cell 5 and the connecting line d is ^ B2, and the sum of the first included angle and the second included angle
Then cell 2 and cell 5 are co-covering cells.
Similarly, please continue to refer to fig. 1B, the first cell is exemplified by the cell 3 of the base station a, the second cell is exemplified by the cell 6 of the base station B, and the second preset value is exemplified by
For example, the connection line between the base station a and the base station B is d. A first included angle between the azimuth angle of the coverage range of the cell 3 and the connecting line d is ^ A3, a second included angle between the azimuth angle of the coverage range of the cell 6 and the connecting line d is ^ B3, and the sum of the first included angle and the second included angle
Then cell 3 and cell 6 are not different coverage cells.
Similarly, please continue to refer to fig. 1B, the first cell is exemplified by cell 1 of base station a, the second cell is exemplified by cell 4 of base station B, and the second preset value is exemplified by
For example, the connection line between the base station a and the base station B is d. Coverage of cell 1A first included angle between the azimuth angle and the connecting line d is ≧ A1, a second included angle between the azimuth angle of the coverage range of the cell 4 and the connecting line d is ≧ B1, and the sum of the first included angle and the second included angle
Then cell 1 and cell 4 are not different coverage cells.
In a possible implementation manner, before determining that the first cell and the second cell are the same coverage cell, it may be further determined whether the first cell and the second cell are the same site. For example, the longitude and latitude of two cells can be used to determine whether the two cells are co-located. If the longitude and latitude of the first cell and the second cell are the same, determining that the first cell and the second cell have the same station address; or if the longitude and latitude of the first cell and the second cell are different, determining that the first cell and the second cell have different station addresses. For example, in fig. 1A, if the longitude and latitude of the cell 1 and the cell 4 are the same, the cell 1 and the cell 4 are co-sited. For another example, in fig. 1B, if the longitude and latitude of the cell 1 and the cell 4 are different, the site of the cell 1 and the site of the cell 4 are different.
Optionally, before the same coverage judgment, two adjacent cells can be screened out based on preset parameters, and the same coverage judgment is carried out, so that the identification of the same coverage cell is more targeted, the identification of unbalanced load is more targeted, and the efficiency of load identification is effectively improved. In one possible implementation, a first cell and a second cell may be selected from a plurality of cells based on first information, where the first information includes one or more of: basic engineering parameters, configuration information, key performance indicators KPI in busy hours and measurement report MR coverage rate; the second cell is a neighboring cell of the first cell.
It is understood that basic parameters include, but are not limited to: at least one of an antenna azimuth angle, an antenna downward inclination angle, an antenna pitch angle, a base station longitude and latitude or same-station-site information; configuration information includes, but is not limited to: at least one of base station information, cell information, working frequency band, bandwidth, uplink frequency point, downlink frequency point or cell transmitting power; busy hour KPIs include, but are not limited to: at least one of the switching times of users, the switching success rate, the number of users of RRC connection in wireless resource control, the PRB utilization rate of a downlink physical resource block, the flow rate, the wireless connection success rate or the wireless disconnection rate.
Example 1, a cell 2, a cell 3, and a cell 4 of a wireless network are provided as an example, where antenna azimuth angles of coverage areas of the cell 1 and the cell 2 have an intersection, antenna azimuth angles of coverage areas of the cell 3, the cell 4, and the cell 1 have no intersection, and antenna azimuth angles of coverage areas of the cell 3, the cell 4, and the cell 2 have no intersection, then the cell 1 and the cell 2 are screened as a first cell and a second cell.
Example 2, a cell 1, a cell 2, a cell 3, and a cell 4 of a wireless network are provided, where the number of successful inter-frequency handovers of the cell 1 and the cell 2 is greater than a preset value, and the number of successful inter-frequency handovers of the cell 3 and the cell 4 is less than the preset value, and then the cell 1 and the cell 2 are screened as a first cell and a second cell.
Example 3, a cell 1, a cell 2, a cell 3, and a cell 4 of a wireless network are provided, where the maximum downlink PRB of the cell 1 and the cell 2 is greater than a preset value, and the maximum downlink PRB of the cell 3 and the cell 4 is less than the preset value, and then the cell 1 and the cell 2 are screened as a first cell and a second cell.
Example 4, a cell 1, a cell 2, a cell 3, and a cell 4 of a wireless network are provided, where the maximum number of users of the cell 1 and the cell 2 is greater than a preset value, and the maximum number of users of the cell 3 and the cell 4 is less than the preset value, then the cell 1 and the cell 2 are screened as a first cell and a second cell.
Step 202: and determining whether the loads of the first cell and the second cell are balanced or not based on the frequency band information of the first cell and the second cell and the load indexes corresponding to the frequency band information.
In a possible implementation manner, the frequency band information of the first cell is a first frequency band, the frequency band information of the second cell is a second frequency band, and the process of determining whether the loads of the first cell and the second cell are balanced based on the frequency band information of the first cell and the second cell and the load indexes corresponding to the frequency band information may be: if the utilization rate of the downlink PRB of the first frequency band is greater than a third preset value, the utilization rate of the downlink PRB of the first frequency band is N times that of the downlink PRB of the second frequency band; or if the number of the downlink users in the first frequency band is greater than the fourth preset value, and the number of the downlink users in the first frequency band is M times that in the second frequency band; determining that a load of the first cell is higher than a load of the second cell; wherein N, M is a positive integer greater than 1.
The values of M and N may be the same or different, and the embodiments of the present application are not particularly limited.
Illustratively, the first frequency band may include 1.8G or 2.1G, and the second frequency band may include 1.8G, 2.1G, or 800M.
Example 1, the first frequency band of the first cell is 1.8G, the second frequency band of the second cell is 2.1G, the third preset value is 10% and the fourth preset value is 30. The utilization rate of the downlink PRB corresponding to the 1.8G frequency band is more than 10%, and the utilization rate of the downlink PRB corresponding to the 1.8G frequency band is N times of the utilization rate of the PRB corresponding to the 2.1G frequency band; or, if the number of downlink users corresponding to the 1.8G frequency band is greater than 30 and the number of 1.8G users is M times of the number of 2.1G users, the load of the first cell is higher than that of the second cell, which causes a problem of load imbalance.
Example 2, the first frequency band of the first cell is 2.1G, the second frequency band of the second cell is 1.8G, and the third preset value is 30%.
