Detailed Description
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, a flowchart illustrating steps of a method for adding a neighbor cell according to an embodiment of the present application is shown, which may specifically include the following steps:
in an example, the first measurement data may include that the terminal detects one or more neighboring cells around and measures signal attribute information thereof after receiving a first measurement request sent by the base station;
the signal attribute information may include signal strength, that is, signal strength information of a neighboring cell.
The base station may query, from the first measurement data sent by the terminal, which neighboring cells are unknown neighboring cells to which no neighboring cell relationship is added, and may prepare to determine whether the unknown neighboring cells meet the addition condition according to signal attribute information in the first measurement data.
in an example, the cell handover success rate may be a cell-level handover success rate, or may also be a handover success rate of a certain frequency band in a cell, where the cell handover success rate may change dynamically, for example, the current cell handover success rate is 90%, but the cell handover success rate at the next time may become 80% with the movement of a terminal or other factors;
the first pilot adding threshold may be a signal strength threshold corresponding to the cell handover success rate, for example, the 4G handover success rate is 79%, and the first pilot adding threshold is greater than-90 db, and is preset by the base station, and is used to determine whether the neighboring cell satisfies the signal condition, and if the signal strength of the neighboring cell is greater than the current signal strength threshold, the signal condition is satisfied, and subsequent determination may be continued.
The base station can periodically count the switching success rate of each frequency band and the switching success rate of the cell-level frequency band, and determine the current first pilot frequency adding threshold.
103, adjusting the first pilot adding threshold to a second pilot adding threshold according to the cell switching success rate, and determining a target neighboring cell of which the signal attribute information meets the second pilot adding threshold;
in an example, the second pilot adding threshold may be a signal strength threshold adjusted according to the current cell handover success rate, for example, when the cell handover success rate is low, the signal strength threshold may be adjusted to be low correspondingly.
Because the cell handover success rate is dynamically changed, when the cell handover success rate changes, the first pilot adding threshold needs to be correspondingly adjusted, for example, the 4G handover success rate is 79%, and the threshold is: greater than-90 db; the success rate of 4G switching is 80% -90%, the threshold is larger than-87 db, the adjusted first pilot frequency adding threshold is used as a second pilot frequency adding threshold, and when the signal attribute information of the adjacent cell meets the second pilot frequency adding threshold, the adjacent cell is used as a target adjacent cell.
In an embodiment of the present application, step 103 may include the following sub-steps:
substep 11, when the cell switching success rate is smaller than a preset success rate threshold, adjusting the first pilot frequency adding threshold to a second pilot frequency adding threshold; wherein the second pilot adding threshold is smaller than the first pilot adding threshold;
in an example, the preset success rate threshold may be a preset cell-level handover success rate threshold, or a frequency-band-level handover success rate threshold, and is used to determine whether the current cell handover success rate is too low, so as to determine whether the current neighbor relation is reasonable.
When the cell switching success rate is smaller than the preset success rate threshold, it is considered that the current neighboring cell relation is unreasonable, and the threshold may be set to be slightly lower than the lower threshold to increase more neighboring cells, if the current 4G switching success rate is smaller than the preset success rate threshold: 80%, add the threshold to the original first pilot: and if the second pilot frequency adding threshold is larger than-87 db, adjusting the second pilot frequency adding threshold to be as follows: and the number of the adjacent cells meeting the signal condition is increased by more than-90 db, the switching success rate is improved on the original basis, and the problems of too late switching, wrong cell switching and the like caused by lack of adjacent cell relations are solved.
Substep 12, when the cell switching success rate is greater than a preset success rate threshold, adjusting the first pilot frequency adding threshold to a second pilot frequency adding threshold; wherein the second pilot adding threshold is greater than the first pilot adding threshold;
in an example, the preset success rate threshold may be a preset cell-level handover success rate threshold, or a frequency-band-level handover success rate threshold, and is used to determine whether the current cell handover success rate is too high, so as to determine whether the current neighboring cell relationship is reasonable.
When the cell switching success rate is greater than a preset success rate threshold, the neighbor cell relation is considered to be basically complete, and only the neighbor cell with a particularly good signal needs to be added, if the current 4G switching success rate is greater than the preset success rate threshold: 90%, add the original first pilot frequency to the threshold: and if the second pilot frequency adding threshold is larger than-87 db, adjusting the second pilot frequency adding threshold to be as follows: greater than-84 db to reduce the number of neighbors that meet the signal conditions.
The embodiment of the invention is not limited to setting the success rate threshold which is too low or too high, and can set the step pilot frequency adding threshold according to the network index, and the cell can select the corresponding threshold to add the adjacent cell according to the index condition of the cell at different cells and different time, thereby ensuring the reasonability of the adjacent cell addition.
And a substep 13 of determining a target neighboring cell for which the signal attribute information satisfies the second pilot frequency adding threshold.
In a specific implementation, when the signal attribute information corresponding to the neighboring cell meets the second pilot adding threshold, if the signal strength corresponding to the neighboring cell is greater than the second pilot adding threshold, the neighboring cell is taken as the target neighboring cell.
In an embodiment of the present application, the signal attribute information may include signal strength, and the substep 13 may include the steps of:
and when the signal intensity is greater than the second pilot frequency adding threshold, taking the adjacent cell corresponding to the signal intensity greater than the second pilot frequency adding threshold as a target adjacent cell.
And after determining the second pilot frequency adding threshold according to the cell switching success rate, when the signal intensity corresponding to the adjacent cell is greater than the second pilot frequency adding threshold, taking the adjacent cell as a target adjacent cell.
And 104, determining neighbor attribute information corresponding to the target neighbor, and adding the neighbor to the target neighbor when the neighbor attribute information meets preset neighbor conditions.
In an example, the neighboring Cell attribute information may include identification information of the target neighboring Cell, such as ECGI (E-UTRAN Cell Global Identifier ) or NRCGI (NR Cell Global Identifier, 5G NR Cell Global Identifier), location information, and frequency point information;
the preset adjacent cell condition may be a distance condition, and if the preset distance threshold of the base station is 200m, the actual distance between the base station and the adjacent cell is 100m, and at this time, the actual distance is smaller than the preset distance threshold, the preset adjacent cell condition is satisfied.
The base station can make the terminal return the neighbor attribute information of the target neighbor by sending the measurement request to the terminal again, and when the neighbor attribute information is judged to meet the preset neighbor condition, the neighbor addition is carried out on the target neighbor.
In an embodiment of the present application, the neighbor cell attribute information includes first location information and first frequency point information corresponding to the target neighbor cell, and whether the neighbor cell attribute information satisfies a preset neighbor cell condition is determined in the following manner:

In an example, the first location information may include current longitude and latitude information of the target neighbor, such as 113 ° 17 'east longitude and 23 ° 8' north latitude;
the first frequency point information may include a frequency point where a target neighboring cell is located, such as 850 MHz;

In an example, the first frequency band coverage radius may include a coverage radius corresponding to first frequency point information of a target neighboring cell, for example, the first frequency point information is 850M, and the coverage radius thereof is 2500M;
the second frequency band coverage radius may include a coverage radius corresponding to second frequency point information of the serving cell;
the preset adjustment coefficient can be configured according to a wireless environment, for example, under the conditions that wireless signals of each frequency band in a coverage hot spot area are dense, the relative neighboring cell relationship is more perfect, and the index is better, the adjustment coefficient can be 1, and under the conditions that the suburb base station distance is large, the coverage range is wide, and the neighboring cell relationship is incomplete, the adjustment coefficient can be set to 1.5.
