Example four
Fig. 4 is a schematic view of a fourth implementation flow of the parameter obtaining method according to the embodiment of the present invention, as shown in fig. 4, the parameter obtaining method according to the embodiment of the present invention includes:
step S401: acquiring a measurement report and/or frequency sweep data of a target cell group;
the target cell group is a pilot frequency adjacent cell, and the pilot frequency adjacent cell comprises a cell to be optimized.
Specifically, the terminal may obtain a measurement report and/or frequency sweep data of the target cell group in the drive test process, that is, obtain a measurement report and/or frequency sweep data of the inter-frequency neighboring cell.
Step S402: detecting whether the cell to be optimized and the specified same-frequency adjacent cell are covered continuously according to the measurement report and/or the sweep frequency data to obtain a detection result;
specifically, as shown in fig. 5, the detecting, by the terminal, whether the cell to be optimized and the specified co-frequency neighboring cell continuously cover according to the measurement report to obtain a detection result includes:
step S4021: acquiring a measurement report and/or frequency sweep data from the cell to be optimized to a specified same-frequency adjacent cell;
step S4022: and when detecting that the measurement report and/or the sweep frequency data meet the preset coverage judgment condition, obtaining a detection result that the cell to be optimized and the specified same-frequency adjacent cell are continuously covered.
In an example, a terminal determines whether a cell a to be optimized and a specified co-frequency neighboring cell b continuously cover or not by using a measurement report and scanning data of the cell a to be optimized, which are obtained as follows:
here, the obtained measurement report and scanning data of the cell a to be optimized are recorded as a; and B, taking the data which is measured in the step A and has the designated same-frequency adjacent region b and the received RSRP difference value of the a and the b is within x dB, and recording the data as AB.
When the AB meets the following preset coverage judgment conditions, obtaining a detection result that the cell to be optimized and the specified same-frequency adjacent cell are continuously covered: 1) the probability median of the RSRP of the cell a to be optimized in the AB is greater than a threshold _ RSRP; wherein, a typical value of the threshold _ rsrp can be-110 dBm; 2) RSRP maximum-RSRP minimum > threshold _ extreme value in AB; wherein, a typical value of the threshold _ extreme value may be 20 dB; 3) AOA maximum-AOA minimum > threshold _ AOA in AB; wherein, a typical value of the threshold _ aoa may be 40 degrees; 4) the proportion of the number of the sampling points in the AB to the number of the sampling points in the A exceeds a threshold _ ratio; wherein a typical value for the threshold _ ratio may take 5%.
In an example, a terminal determines whether a cell a to be optimized and a specified co-frequency neighboring cell b are covered continuously by an acquired measurement report of the cell a to be optimized, which is specifically as follows:
step 1, obtaining measurement report sampling point data from a cell a to be optimized to a specified same-frequency adjacent cell b;
step 2, counting the total number of all sampling points meeting the following preset coverage judgment conditions, and if the proportion of all sampling points is more than 10%, judging that the cell a to be optimized to the specified same-frequency adjacent cell b is in continuous coverage: 1) the RSRP of the cell a > to be optimized is not less than-95 dBm; the RSRP of the specified same-frequency adjacent cell b > adjacent cell is between-95 dBm and-110 dBm and is more than 3dB greater than the RSRP of the cell a to be optimized.
In an example, a terminal determines whether a cell a to be optimized and a specified same-frequency neighboring cell b are covered continuously by acquired scanning data of the cell a to be optimized, which is specifically as follows:
step 1 a: according to longitude and latitude parameter information of the cell a to be optimized and the specified same-frequency adjacent cell b, a switching zone area between the cell a to be optimized and the specified same-frequency adjacent cell b is defined;
step 2 a: acquiring all frequency sweep data of the same-frequency adjacent regions in the switching zone region;
and step 3 b: calculating the median of all RSRP values in the sweep frequency data;
and step 3 d: and when the sweep frequency data is detected to meet a preset coverage judgment condition, namely the median is not less than-95 dBm, determining whether the cell a to be optimized and the specified same-frequency adjacent cell b are continuously covered.
Step S403: and determining the adjustment soft handover parameters of the pilot frequency adjacent cell when the detection result indicates that the cell to be optimized and the specified same-frequency adjacent cell are covered continuously.
Specifically, when the terminal determines that the cell to be optimized and the specified co-frequency neighboring cell are covered continuously, the terminal may determine an adjusted soft handover parameter (CIO) of the inter-frequency neighboring cell according to the cell frequency band to which the terminal belongs.
In an example, if a cell a to be optimized and a specified same-frequency neighboring cell b are both D-frequency-band adjacent continuous coverage cells, a cell c is an F-frequency-band cell, and b and c share a station and cover in the same direction, the CIO of the cell a to be optimized to the different-frequency neighboring cell c can be considered as y, and the value is 4.9; if the cell a to be optimized and the specified same-frequency neighboring cell b are F-frequency-band adjacent continuous coverage cells, the cell c is a D-frequency-band cell, and the cells b and c share stations and cover in the same direction, the CIO from the cell a to be optimized to the pilot frequency neighboring cell c can be considered as 0 or set as x; where x is a negative number that can be set, i.e. the probability of the UE switching from the cell a to be optimized to the inter-frequency neighbor c is increased from the cell load point of view.
Therefore, the parameter acquisition method can accurately set the switching among the pilot frequency cells, and can improve the user throughput of the whole network and the power consumption of the battery; meanwhile, the frequency of pilot frequency switching is effectively reduced, so that the switching of cells with the same frequency is realized as much as possible, and the user perception is good.
