Description
Technical Field

Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

Step S120: and acquiring the frequency point information of each candidate 4G cell in the candidate 4G cell set.

The preset anchor point station frequency points refer to: specific frequency point values of the frequency points corresponding to anchor point stations which need to be set in the 5G cell to be detected depend on actual service requirements, and the invention is not limited to the specific frequency point values. Specifically, candidate 4G cells whose frequency point information matches the frequency point of the preset anchor station are added to a first candidate hierarchical list, and candidate 4G cells whose frequency point information does not match the frequency point of the preset anchor station are added to a second candidate hierarchical list. Wherein at least one of the first candidate level list and the second candidate level list is not empty.
Step S140: a first type of metric corresponding to a candidate 4G cell in the first candidate hierarchical list is acquired and/or a second type of metric corresponding to a candidate 4G cell in the second candidate hierarchical list is acquired.
Specifically, for candidate 4G cells in the first candidate hierarchical list, a first type of indicator related to cell health is collected. All the indexes which can be used for calculating the health degree of the cell can be used as the first-class index, and the invention is not limited to this.
A second type of indicator associated with the device is collected for the candidate 4G cells in the second candidate hierarchical list. All the various indexes capable of reflecting the cell equipment information can be used as the second index, which is not limited in the present invention.
Step S150: and selecting a target cell from the candidate 4G cell set according to the first-type index and/or the second-type index, and setting an anchor point station based on the target cell.
The health degree of each candidate 4G cell in the first candidate hierarchical list can be calculated based on the first type of indexes, so that the cell with better health degree is selected as the target cell. In addition, when the first candidate hierarchical list is empty or the health degree of each cell in the first candidate hierarchical list is poor, whether a candidate 4G cell capable of being upgraded to the anchor station exists is judged based on the second type of index, and the upgrade processing is executed on the candidate 4G cell.
Therefore, according to the method, each candidate 4G cell is divided into two different candidate levels according to whether the frequency point information of the candidate 4G cell is matched with the frequency point of the preset anchor point station, and different acquisition indexes are set for different candidate levels respectively, so that whether the cell is suitable for being used as the anchor point station or not is evaluated from different dimensions according to different candidate levels, and the setting result is more reasonable.
Example two
Fig. 2 shows a flowchart of an anchor point station setting method for a 5G cell according to a second embodiment of the present invention. As shown in fig. 2, the method includes:
step S210: and determining a candidate 4G cell set corresponding to the 5G cell to be detected according to the longitude and latitude information of the 5G cell to be detected and a preset search radius.
The preset search radius can be flexibly set according to factors such as building density of a region where the 5G cell to be detected is located, and a plurality of 4G cells adjacent to the 5G cell to be detected can be screened from a plurality of 4G cells to form a candidate 4G cell set through the search radius.
Step S220: and acquiring the frequency point information of each candidate 4G cell in the candidate 4G cell set.
Specifically, the base station device acquires frequency point information of each candidate 4G cell in the candidate 4G cell set.
Step S230: and judging whether the frequency point information of each candidate 4G cell is matched with the frequency point of the preset anchor point station, and adding each candidate 4G cell into the first candidate hierarchical list and/or the second candidate hierarchical list according to the judgment result.
The preset anchor point station frequency points refer to: specific frequency point values of the frequency points corresponding to anchor point stations which need to be set in the 5G cell to be detected depend on actual service requirements, and the invention is not limited to the specific frequency point values. Specifically, candidate 4G cells whose frequency point information matches the frequency point of the preset anchor station are added to a first candidate hierarchical list, and candidate 4G cells whose frequency point information does not match the frequency point of the preset anchor station are added to a second candidate hierarchical list. Wherein at least one of the first candidate level list and the second candidate level list is not empty.
Step S240: a first type of metric corresponding to a candidate 4G cell in the first candidate hierarchical list is acquired and/or a second type of metric corresponding to a candidate 4G cell in the second candidate hierarchical list is acquired.
Specifically, for candidate 4G cells in the first candidate hierarchical list, a first type of indicator related to cell health is collected. All the indexes which can be used for calculating the health degree of the cell can be used as the first-class index, and the invention is not limited to this. In this embodiment, the first type of index includes: a status information indicator; and the status information indicators further include a coverage type indicator, a capacity type indicator, and a quality type indicator. Wherein, the coverage class index comprises: cell downlink MR coverage; the capacity class indexes include: the method comprises the following steps that the uplink PRB utilization rate of the busy cell segment, the downlink PRB utilization rate of the busy cell segment and the number of synchronous state users of the busy cell segment are obtained; the quality class indexes comprise: the cell uplink signal-to-noise ratio.
A second type of indicator associated with the device is collected for the candidate 4G cells in the second candidate hierarchical list. All the various indexes capable of reflecting the cell equipment information can be used as the second index, which is not limited in the present invention. In this embodiment, the second type of index includes: an equipment model index; and the equipment model index is used for reflecting whether the equipment supports the preset anchor point station frequency point.
Step S250: and if the first candidate hierarchical list is not empty, calculating the health degree of the cell according to the first type index of the candidate 4G cells in the first candidate hierarchical list, selecting a target cell from the first candidate hierarchical list according to the health degree calculation result, and setting the target cell as an anchor station.
And selecting the cell with better health degree as the target cell so as to improve the working efficiency of the anchor point station.
Step S260: if the first candidate level list is empty or the cell health of each candidate 4G cell in the first candidate level list does not meet the standard; judging whether the second candidate level list comprises candidate 4G cells capable of being upgraded to the anchor point station or not according to the second type indexes of the candidate 4G cells in the second candidate level list; if yes, determining the candidate 4G cell capable of being upgraded to the anchor point station as a target cell, and upgrading the target cell to the anchor point station.
Wherein, the fact that the cell health degree of each candidate 4G cell in the first candidate hierarchical list does not meet the standard means that: the cell health of each candidate 4G cell in the first candidate hierarchical list is poor or the health value is less than a preset health threshold.
In this embodiment, the preset search radius may be determined according to the building density of the region where the 5G cell to be detected is located. For example, for an urban area, where the building density is large, the search radius is set small; for suburbs where the building density is small, the search radius is set larger.
Therefore, the embodiment can automatically traverse all 4G cells of the network management by reasonably setting the search radius and combining the longitude and the latitude of the 5G cell to be detected; also, a concept of candidate hierarchies is proposed: dividing the preliminary candidate cell into a first candidate level and a second candidate level according to whether the preliminary candidate cell contains the anchor station frequency point, so as to realize differential processing aiming at different levels; moreover, an algorithm of the cell health degree is provided: the current health degree of the cell is calculated and evaluated by collecting performance indexes of a coverage class, a capacity class and a quality class, so that the quality of the anchor point station is ensured.
For convenience of understanding, the following describes specific implementation details of the second embodiment of the present invention in detail by taking a specific example as an example:
in the example, starting from the desirability of 5G anchor station selection, a selection strategy and a method when anchor station decision is improved, an analysis processing device (namely an execution main body of each step in the invention) is added between an eNODE (namely Evolved Node B, also called Evolved Node B, eNB for short, and is the name of a base station in LTE) and a network manager, the device can traverse 4G cells in a search range, collect frequency points, performance and hardware related information from the eNODE, improve a selection strategy, improve the overall anchorability, timeliness and accuracy when the anchor station is selected, and accordingly improve user perception.
Fig. 5 shows a 5G anchor station selection diagram. As shown in fig. 5, the present example mainly executes the following processing by an analysis processing apparatus (specifically including a search module and a decision module) installed between the eNODEB and the network manager:
firstly, inputting the longitude and latitude of a 5G cell to be detected;
acquiring 4G cell CI within the search radius according to the algorithm;
collecting cell frequency point information, and bringing the searched cells into different candidate levels;
fourthly, collecting different information of the cell according to different candidate levels;
and fifthly, outputting final anchor point information according to the decision.
Therefore, the device traverses all cells of the current network in a network management system according to the latitude and longitude of the 5G cell to be detected input by a user, obtains the cell CI within the search radius range through distance judgment, collects cell frequency point information to the eNODE B according to the obtained cell CI, brings the searched cells into different candidate levels, collects different cell information to the eNODE B again according to the different candidate levels, and finally outputs final anchor point station information to the user through calculating the cell health degree or checking cell hardware information so that the terminal can fall back better.
When in specific implementation, the method mainly comprises the following steps:
the method comprises the following steps: the user inputs the latitude and longitude information (X) of the 5G cell to be detected to the device5G,Y5G)；
Step two: the device acquires a 4G cell set meeting the conditions according to the search radius D:
firstly, the device acquires longitude and latitude information omega of all cells of the current network1＝{(Xi,Yi) 1, …, n, where n is the number of cells in the current network 4G;
then, the device calculates the distance omega between the 5G cell to be detected and the current network celldis＝{Di|i＝1,...,n}
Di＝R×arcos[cos(Yi)×cos(Y5G)×cos(Xi-X5G)+sin(Yi)×sin(Y5G)]
Wherein R is 6371.004km, which is the average radius of the earth.
Finally, the device is according to ΩdisObtaining a cell CI set omega within the range of the search radius DCISo that the set ΩCID corresponding to any inner celliSatisfies the following conditions:
Di≤D,i＝1,…,m
wherein m is the number of the existing network 4G cells meeting the condition, the search radius D can be set by a user according to the scene, if the urban area can appropriately narrow the search range, and the suburban area can appropriately expand the search range.
Step three: the device collects omega according to the obtained CICIAcquiring frequency point information of corresponding cells from the eNODEB according to the frequency point informationDifferent frequency point information will be omegaCIDifferent candidate levels were included:
1. if the frequency points of the cells are FDD1800, F1 or F2, the cells are included in the first candidate level omegaCI1；
2. If the cell frequency point is not FDD1800, F1 or F2, then it is included in the second candidate level omegaCI2。
Step four: the device collects different information to the eNODEB according to different candidate levels:
1. if omegaCI1If not, acquiring the state information indexes of the cells in the set, specifically the coverage indexes: the downlink MR coverage rate M of the cell (the sampling point proportion of which the RSRP is less than-110 dBm); capacity index: uplink PRB utilization rate P of cell busy periodOn the upper partThe utilization rate P of downlink PRB in the busy period of the cellLower partThe number U of synchronous state users in the busy period of the cell; quality index: the uplink signal-to-noise ratio S (the sampling point proportion of SINR less than-3 dB) of the cell;
2. if omegaCI1If it is empty, collect omegaCI2RRU equipment model in the cell.
Step five: the device judges and decides the final anchor point station information according to the collected different information:
1. if omegaCI1If it is not null, i.e. it is the status class information indicator that is collected, the device first calculates ΩCI1Inner cell health Φ:
where i is 1, …, k, k is the set ΩCI1The number of cells. Then the device selects the cell with the best cell health degree as an anchor cell and feeds back the anchor cell to the user, so that the requirements of the anchor cell are as follows:
Φanchor point＝max{Φi|i＝1,…,k}
2. If omegaCI1If the current network equipment is empty, namely the RRU equipment model is acquired, the device outputs information whether the current network equipment can be upgraded into an anchor point station according to the equipment model:
A. if the equipment supports the FDD1800 frequency point, the F1 frequency point or the F2 frequency point, the upgrading to an anchor point station is prompted, and cell information corresponding to the corresponding equipment is fed back;
B. if the device does not support the FDD1800 frequency point, F1 frequency point or F2 frequency point, or omega frequency pointCI2And if the current station is empty, prompting that an anchor station needs to be newly built.
The concrete description is as follows: in the example, according to latitude and longitude information of a 5G cell input by a user, an analysis processing device installed between an eNODE B and a network manager is mainly used, firstly, all 4G cells of the existing network are traversed through a search radius to obtain a primary candidate cell CI, then, the candidate cell is divided into a first candidate level and a second candidate level by collecting cell frequency point information, finally, different information is collected according to different candidate cell levels, and the best anchor point station information is determined by calculating the cell health degree or checking cell hardware information. Wherein, in the process of 5G final anchor station selection and identification, the decision algorithm shown in fig. 6 needs to be adopted. Fig. 6 shows a schematic diagram of a decision algorithm in the selection process of an anchor station.
In conclusion, the device in the example can ensure the timeliness, comprehensiveness and accuracy of the 5G anchor station selection. The method specifically comprises the steps of traversing all 4G cells possibly becoming anchor points in a search radius according to the longitude and latitude of a 5G cell input by a user through an analysis processing device arranged between an eNODE B and a network manager, dividing candidate cells into different levels according to collected frequency point information, calculating the cell health degree or checking cell equipment information according to the candidate levels, and deciding the best anchor point station information.
The method mainly improves the accuracy and comprehensiveness of the selection of the anchor point station of the 5G cell by determining the search radius, dividing the candidate hierarchy of the cell and calculating the health degree of the cell, thereby improving the satisfaction degree of the actual use of a user.
