Description
Technical Field

Background
With the continuous development and upgrade of mobile networks, mobile communication networks enter the 5G era, 5G is large-scale to enter the network, 5G investment construction meets the unprecedented challenges, and 4G networks are developed after several years of construction, so that mature independent networks with quite large scale are formed, and in consideration of cost factors and technical factors, the initial stage of 5G construction is mainly based on NSA (non-independent networking), namely 4G core networks are used, and the 5G networks are transmitted to the core networks from a wireless side or are transmitted upwards through the 4G core networks, so that corresponding anchor point station cells are matched in 5G construction at the present stage, and the current 5G anchor point station selection strategy can be roughly divided into 4 steps: 1. determining the longitude and latitude of a 5G cell; 2. according to the longitude and latitude of the 5G cell, manually selecting a 4G cell within a certain range nearby; 3. manually inquiring the frequency point information of the nearby 4G cells; 4. selecting a cell with an anchor point frequency point and closest to the anchor point frequency point as an anchor point cell, and directly creating an anchor point if no anchor point frequency point exists nearby.
The existing 5G anchor point station selection strategy mainly has the following three defects: 1. timeliness aspect: the existing strategy is that the aspects of 4G cell selection, frequency point inquiry, distance calculation and the like are manually calculated and manually checked, and the manual detection of 5G anchor points inevitably reduces the working efficiency along with the network access of a large number of 5G sites; 2. overall aspects: at present, only the cells which can be directly used as the anchor point are considered when the anchor point is selected, but the cells which do not contain the frequency point of the anchor point can be directly removed, however, the cells can be changed into the cells of the anchor point through upgrading, so that the cost for greatly building the anchor point is saved; 3. in terms of accuracy, the existing strategy is to select a cell which is closest to the cell and has an anchor point station frequency point, but if the cell is worse, the performance index is seriously deteriorated, and the cell is continuously used as the anchor point station cell, so that a larger side effect is generated when 5G falls back to a 4G core network, and the actual use perception of a user is further influenced.

The health degree of each candidate 4G cell in the first candidate level list can be calculated based on the first type index, so that a cell with better health degree is selected as a target cell. In addition, when the first candidate level list is empty or the health degree of each cell in the first candidate level list is poor, whether a candidate 4G cell capable of being upgraded to an anchor station exists or not is judged based on the second type index, and upgrading processing is performed 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, and different acquisition indexes are respectively set for the different candidate levels, so that whether the cell is suitable to serve as the anchor point or not is evaluated from different dimensions for the different candidate levels, and the setting result is more reasonable.

step S210: and determining a candidate 4G cell set corresponding to the 5G cell to be detected according to the latitude and longitude information of the 5G cell to be detected and a preset search radius.
The preset searching radius can be flexibly set according to factors such as building density of the 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 searching radius.
Step S220: and collecting frequency point information of each candidate 4G cell in the candidate 4G cell set.
Specifically, the base station apparatus collects frequency point information of each candidate 4G cell in the candidate 4G cell set.

The preset anchor point station frequency point is as follows: specific frequency point values of frequency points corresponding to anchor points needing to be set for 5G cells to be detected depend on actual service requirements, and the invention is not limited to the specific frequency point values. Specifically, candidate 4G cells with frequency point information matched with the frequency point of the preset anchor point station are added into a first candidate level list, and candidate 4G cells with frequency point information not matched with the frequency point of the preset anchor point station are added into a second candidate level list. Wherein at least one of the first candidate level list and the second candidate level list is not empty.
Step S240: a first class of indicators corresponding to candidate 4G cells in the first candidate level list is acquired and/or a second class of indicators corresponding to candidate 4G cells in the second candidate level list is acquired.
Specifically, for candidate 4G cells in the first candidate level list, a first type of indicator related to cell health is collected. All kinds of indexes which can be used for calculating the health degree of the cell can be used as the first kind of indexes, and the invention is not limited to the first kind of indexes. In this embodiment, the first type of index includes: a status information index; and the status information index further includes an overlay class index, a capacity class index, and a quality class index. Wherein, the coverage class index includes: cell downlink MR coverage; the capacity class index includes: the method comprises the steps of (1) using an uplink PRB in a cell busy period, using a downlink PRB in the cell busy period, and using the same-gait user number in the cell busy period; the quality class index comprises: cell uplink signal-to-noise ratio.
And acquiring a second type of index related to the equipment aiming at the candidate 4G cells in the second candidate level list.

The cell with better health degree is selected as a target cell, so that the working efficiency of the anchor point station is improved.
Step S260: if the first candidate level list is empty or the cell health degree of each candidate 4G cell in the first candidate level list does not reach the standard; judging whether the candidate 4G cells capable of being upgraded to the anchor point stations are contained in the second candidate level list according to the second type index of the candidate 4G cells in the second candidate level list; if yes, the candidate 4G cell which can be upgraded to the anchor point station is determined to be a target cell, and the target cell is upgraded to the anchor point station.
Wherein, the cell health degree of each candidate 4G cell in the first candidate level list does not reach the standard means that: the cell health of each candidate 4G cell in the first candidate hierarchy 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 urban areas where building concentration is large, the search radius is set to be small; for suburban areas, where building concentration is small, the search radius is set to be large.
Therefore, the embodiment can automatically traverse all 4G cells of the network manager by reasonably setting the searching radius and combining the longitude and latitude of the 5G cells to be detected; and, the concept of candidate hierarchy is proposed: dividing the preliminary candidate cell into a first candidate level and a second candidate level according to whether the anchor point station frequency points are contained or not so as to realize differentiation processing aiming at different levels; moreover, algorithms for cell health are proposed: the current health degree of the evaluation cell is calculated by collecting performance indexes of coverage class, capacity class and quality class, so that the quality of the anchor point station is ensured.
For easy understanding, the following details of implementation of the second embodiment of the present invention are described in detail by taking a specific example as an example:
the method and the device for selecting the anchor point from the 5G anchor point start point selection are improved, a selection strategy and a method for deciding the anchor point are improved, an analysis processing device (namely an execution main body of each step in the invention) is added between the eNODEB (namely the Evolved Node B, also called the Evolved Node B, for short, eNB, which is the name of a base station in LTE) and the network manager, the device can traverse the 4G cell in the search range, collect relevant information of frequency points, performance and hardware class to the eNODEB, the selection strategy is improved, the comprehensiveness, timeliness and accuracy of the anchor point selection are improved, and therefore user perception is improved.
Fig. 5 shows a 5G anchor station selection diagram. As shown in fig. 5, the present example mainly performs the following processing by an analysis processing apparatus (specifically including a search module and a decision module) installed between eNODEB and a network manager:
(1) inputting longitude and latitude of a 5G cell to be detected;
(2) the device acquires a 4G cell CI within a search radius according to an algorithm;
(3) collecting cell frequency point information, and incorporating the searched cell into different candidate levels;
(4) collecting different information of a cell according to different candidate levels;
(5) and outputting final anchor point information according to the decision.
Therefore, the device traverses all cells of the current network in the network management according to the longitude and latitude of the 5G cell to be detected, acquires the cell CI within the searching radius range through distance judgment, acquires the cell frequency point information from the eNODEB according to the acquired cell CI, brings the searched cell into different candidate levels, acquires the different cell information from the eNODEB again according to the different candidate levels, and finally outputs the final anchor point information to the user through calculating the cell health degree or checking the cell hardware information so that the terminal can fall back better.
The method mainly comprises the following steps of:
step one: the user inputs the longitude and latitude information (X) of the 5G cell to be detected to the device 5G ,Y 5G )；
Step two: the device acquires a 4G cell set meeting the condition according to the search radius D:
firstly, the device acquires longitude and latitude information omega of all cells of the current network 1 ＝{(X i ,Y i ) I=1, …, n }, n being the number of cells of the current network 4G;
then, the device calculates the distance omega between the 5G cell to be detected and the current network cell dis ＝{D i |i＝1,...,n}
D i ＝R×arcos[cos(Y i )×cos(Y 5G )×cos(X i -X 5G )+sin(Y i )×sin(Y 5G )]
Where r= 6371.004km is the average radius of the earth.
Finally, the device is according to Ω dis Acquiring a set Ω of cells CI within a search radius D CI So that the aggregate Ω CI D corresponding to any cell in i The method meets the following conditions:
D i ≤D,i＝1,…,m
where m is the number of current network 4G cells satisfying the condition, the search radius D may be set by the user according to the scenario, for example, the urban area may properly reduce the search range, and the suburban area may properly expand the search range.
Step three: the device gathers omega according to the acquired CI CI Acquiring frequency point information of a corresponding cell from the eNODEB, and converting omega into omega according to different frequency point information CI Incorporating different candidate levels:
1. if the frequency point of the cells is FDD1800, F1 or F2, the cells are brought into a first candidate level omega CI1 ；
2. If the cell frequency point is not FDD1800, F1 or F2, the cell frequency point is included in the second candidate level omega CI2 。
Step four: the device collects different information to enodebs according to different candidate levels:
1. if omega CI1 If the coverage type index is not empty, acquiring the state information index of the cell in the set, specifically, the coverage type index: cell downlink MR coverage M (sampling point proportion of RSRP less than-110 dBm); capacity class index: uplink PRB utilization P in cell busy period Upper part Cell busy period downlink PRB utilization rate P Lower part(s) The number U of users in the same gait in the busy cell period; quality class index: cell uplink signal-to-noise ratio S (SINR less than-3 dB sample point ratio);
2. if omega CI1 If it is empty, collect Ω CI2 RRU device model in the cell.
Step five: the device judges and decides final anchor point station information according to the collected different information:
1. if omega CI1 If the state information index is not empty, i.e. the state information index is acquired, the device firstly calculates omega CI1 Inner cell health Φ:
where i=1, …, k, k is the set Ω CI1 Is a cell number of (a) in the cell. Then the device selects the cell with the best cell health degree as the anchor cell to feed back to the user, so that the cell meets the following conditions:
Φ anchor point ＝max{Φ i |i＝1,…,k}
2. If omega CI1 If the current network equipment is empty, that is, the RRU equipment model is collected, the device outputs information whether the current network equipment can be upgraded to an anchor station according to the equipment model:
A. if the equipment supports the frequency point of FDD1800, F1 or F2, prompting the upgrading to an anchor point station and feeding back the cell information corresponding to the corresponding equipment;
B. if the device does not support FDD1800, F1 or F2 frequency points, or omega CI2 And is also empty, prompting that a new anchor station is needed.
The concrete explanation is as follows: according to the method, an analysis processing device arranged between an eNODEB and a network manager is mainly used, according to 5G cell longitude and latitude information input by a user, all 4G cells of an existing network are traversed through a search radius to obtain primary candidate cells CI, the candidate cells are divided into a first candidate level and a second candidate level through collecting cell frequency point information, finally different information is collected according to different candidate cell levels, and optimal anchor point station information is judged through calculating cell health or checking cell hardware information. In the process of selecting and identifying the 5G final anchor station, the decision algorithm shown in fig. 6 needs to be adopted. Fig. 6 shows a schematic diagram of a decision algorithm in the anchor station selection process.
In summary, the apparatus in this example can ensure timeliness, comprehensiveness, and accuracy of 5G anchor station selection. According to the method, an analysis processing device arranged between the eNODEB and a network manager is used for traversing all the 4G cells possibly becoming anchor points in a search radius according to the longitude and latitude of a 5G cell input by a user, then dividing candidate cells into different levels according to acquired frequency point information, and then calculating the health degree of the cells or checking the equipment information of the cells according to the candidate levels to determine the optimal anchor point information.
The method improves the accuracy and the comprehensiveness of 5G cell anchor point station selection mainly through the determination of the search radius, the division of cell candidate levels and the calculation of cell health degree, thereby improving the actual use satisfaction degree of users. It can be seen that this approach is a major technical improvement over the prior art:
(1) Search radius: the concept of the search radius is provided, all 4G cells of the network manager can be automatically traversed by combining the longitude and latitude of the 5G cells to be detected through the search radius, the preliminary candidate cells are screened out for subsequent calculation, the whole process is automatically executed by the device, manual participation is avoided, and algorithm timeliness is improved;
(2) Candidate hierarchy: the method comprises the steps of providing a candidate level concept, dividing a preliminary candidate cell into a first candidate level and a second candidate level according to whether the anchor point station frequency points are contained or not so as to acquire different information for different candidate levels, introducing the concept not only considers the cell containing the anchor point station frequency points, but also considers the cell which does not contain the anchor point station frequency points but is possibly upgraded to the anchor point station, and improving the comprehensiveness of selection;
(3) Cell health: the device calculates and evaluates the current health degree of the cell by collecting performance indexes of coverage class, capacity class and quality class aiming at the cell containing the anchor point frequency point, thereby selecting the cell with the best health degree as the cell of the anchor point, avoiding the traditional strategy to directly select the cell closest to the cell as the anchor point, and further improving the accuracy of the selection of the anchor point
In summary, the embodiment of the invention overcomes the defects of the existing 5G anchor point station selection technology, and realizes the final 5G anchor point station selection by traversing the search radius, determining the cell candidate level and calculating the cell health degree, thereby improving the selection timeliness, improving the accuracy and optimizing the actual perception of the user on the premise of ensuring that the cells in all the search radii are effectively analyzed.
