As shown in fig. 3, 5G is a brand new technical system, and a Massive MIMO technology is used, so that a LTE wide beam coverage mode is changed, and a narrow beam is used for coverage, so that the device type of the wireless side device is largely changed, where the most varied device type is that the number of receiving channels of the AAU device is largely changed, and a single 2TR device is changed into a device type with diversified channel numbers such as 64TR, 32TR, 16TR, 8TR, and the like. However, how to select a proper equipment type for the area where the 5G base station is to be built becomes a difficult point at present, and is an important problem of balancing the network deployment cost of operators; in order to solve the above problem, in the device type selection method provided in the embodiment of the present invention, the user may determine the corresponding relationship between the SINR interval of 5G and the device type by using the historical CQI of the target area in the fourth generation mobile communication technology (the 4th generation mobile communication technology, which is abbreviated as 4G); then, determining a second target SINR of the designated area under a second mobile communication technology through a scene map in the designated area; further, the type of the equipment to be deployed in the scene where the 5G base station is deployed is determined according to the corresponding relation and the second target SINR, and the problem of how to select appropriate AAU equipment according to the user requirement of the base station area to be built is solved.
Illustratively, taking the first mobile communication technology as 4G, the second mobile communication technology as 5G, the device types include 16TR device, 32TR device, and 64TR device, and the designated area is the proposed base station area, and the specific implementation process is as follows:
example one
An embodiment of the present invention provides an apparatus model selection method, as shown in fig. 4, including:
s101, acquiring historical CQI of a target area under a first mobile communication technology and a scene map in a designated area.
It should be noted that, in practical applications, the following relationship exists between the target area and the designated area:
firstly, a designated area belongs to (here, the designated area is based on the division of an administrative division) a target area, such as: the designated area is a Changan area in the city of Xian, and the target area is the city of Xian; or the designated area is a Changan area in the city of Western Ann, and the target area is an Amaran area in the city of Western Ann; or the designated area is the Changan area Guo Du in Xian city, and the target area is the Changan area in Xian city.
When the target area and the designated area have the relationship, the actual requirements of the user in the designated area can be determined more accurately.
Secondly, the designated area does not belong to the target area, such as: the designated area is Changan area in Xian city, and the target area is Beijing city; or, the designated area is the city of Xian, and the target area is the city of Beijing.
When the target area and the designated area have the relationship, the actual requirements of the users in the designated area can be estimated.
It should be noted that, in an actual application, in order to more accurately determine the actual demand of the user in the designated area, MR data of all urban areas, suburban areas and open areas in the jurisdiction area (target area) to which the designated area belongs in a preset time period (for example, the preset time period may be data of an all-day measurement report (hereinafter, referred to as "MR") of one working day and one holiday in a next week) may be obtained. Because of the correlation between the coverage and capacity of the base station and the sinr (cqi), we choose 4G of MR data as the decision parameter. The method comprises the following steps:
the following table is header information about 4G CQI in MR:
and selecting MR data in the 4G current network within a preset time period (such as 3 months) to determine the distribution condition of the CQI (namely historical CQI). Table 1 shows header information about CQI in MR data.
TABLE 1
The average occurrence of each CQI on weekdays and holidays was calculated by table 1:
Figure BDA0002204903640000072
wherein i represents the total times of reporting the full-bandwidth CQI by the air interface, and i belongs to [0, 15 ]],CQIwCQI indicating a working dayeCQI indicating holidays.
S102, according to the historical CQI and the first mapping relation between the SINR under the second mobile communication technology and the CQI under the first mobile communication technology, the SINR under the second mobile communication technology is determined.
Optionally, determining the SINR in the second mobile communication technology according to the historical CQI and the first mapping relationship between the SINR in the second mobile communication technology and the CQI in the first mobile communication technology, as shown in fig. 5, includes:
s1020, determining the SINR under the second mobile communication technology according to the historical CQI and a first mapping relation between the SINR under the second mobile communication technology and the CQI under the first mobile communication technology; wherein the first mapping relationship comprises:
SINR=1.9346×CQI-6.799;
wherein SINR represents SINR in the second mobile communication technology, and CQI represents CQI in the first mobile communication technology.
It should be noted that, in practical applications, when the mapping relationship between the CQI in the first mobile communication technology and the SINR in the second mobile communication technology is obtained, the relationship between the 4G and the CQI may be obtained by comparing the relationship between the CQI of the 4G and the SINR; further combining the relationship between the 4G and the CQI, the corresponding relationship between the 4G CQI and the 5G SINR is determined, as shown in fig. 6 below, and basically satisfies a linear relationship, and can be estimated by using the following formula:
SINR=1.9346×CQI-6.799。
s103, clustering SINRs under the second mobile communication technology, and determining a central value of each category under the second mobile communication technology.
Optionally, the SINR under the second mobile communication technology is clustered, and a central value of each category under the second mobile communication technology is determined, where fig. 7 includes:
s1030, clustering the SINRs under the second mobile communication technology according to a K-means clustering algorithm (K-means for short), and determining the central value of each category under the second mobile communication technology.
It should be noted that, in practical applications, the k-means algorithm is a very typical clustering algorithm based on distance, and the distance is used as an evaluation index of similarity, that is, the closer the distance between two objects is, the greater the similarity between the two objects is. The algorithm considers clusters to be composed of closely spaced objects, and therefore targets the resulting compact and independent clusters as final targets. The distance formula used is as follows:
Figure BDA0002204903640000081
where V represents the distance, x, of the SINR of 5G from the center value (also called centroid) of the specified classjSINR, μ, representing the jth 5GiRepresenting the center value of the ith category.
The specific implementation process is as follows:
1. k SINRs of 5G are randomly selected from the N SINRs of 5G (the SINR under the second mobile communication technology is determined according to the historical CQI and the first mapping relation between the SINR under the second mobile communication technology and the CQI under the first mobile communication technology).
2. For each remaining 5G SINR (including the SINR determined for the second mobile communication technology based on the first mapping of SINR for the second mobile communication technology to CQI for the first mobile communication technology and the historical CQI), its distance V to each center value is measured and assigned to the category of the nearest center value.
3. And recalculating the obtained central values of the various categories.
4. And iterating for 2-3 steps until the new central value is equal to the original central value or smaller than a specified threshold value, and finishing the algorithm.
The procedure implemented with programming is as follows:
inputting: k, data [ n ];
(1) selecting k initial center values, e.g., c [0] ═ data [0], … c [ k-1] ═ data [ k-1 ];
(2) for data [0] …. data [ n ], compare with c [0] … c [ k-1], respectively, and mark as i assuming minimum difference with ci;
(3) for all points marked as i, recalculating c [ i ] = { the sum of all data [ j ] marked as i }/the number marked as i;
(4) and (3) repeating the steps (2) and (3) until all the changes of the c [ i ] values are smaller than a given threshold value.
In practical application, when the SINR under the second mobile communication technology is clustered by k-means, it is not preferable that the more the center values (each center value corresponds to a category) are selected, as shown in fig. 8 (the abscissa is the number of categories, and the ordinate is the average profile value), the clustering result obtained when the selected center values are 2 is optimal, the clustering result obtained when the selected center values are 3 is slightly poor, and the clustering result obtained when the selected center values are 4 is slightly poor; but according to the cost of the equipment and the requirement of the multi-antenna multi-channel gain of the 5G Massvie MIMO, clustering results need to be divided into 3-4 types; therefore, based on the requirement of optimal cost performance, when clustering is carried out on SINR under the second mobile communication technology through k-means, 3-4 central values are selected so as to obtain 3-4 classes; illustratively, the specific implementation process of clustering the SINRs under the second mobile communication technology is as follows:
1. in terms of the classification into 3 classes, the classification case is given in fig. 9 and the contour case is given in fig. 10.
2. Then, the central value of each category in the clustering algorithm is obtained and is marked as CT1,CT2,CT3
S104, determining an SINR interval under the second mobile communication technology according to the central value, matching the SINR interval with the device type, and determining the corresponding relation between the SINR interval and the device type.
It should be noted that, in practical applications, the center value of each category can be obtained through S103, so that SINR intervals can be divided according to the center value; illustratively, the SINR interval may be divided as follows:
Figure BDA0002204903640000101
then, matching the SINR interval with the equipment type; exemplarily, the corresponding relationship between the device type and the SINR interval may be determined in the following manner; wherein, the corresponding relation includes:
the requirement of the 16TR equipment meets the interval T1;
the requirement of the 32TR equipment meets the T2 interval;
the 64TR device is required to meet the T3 interval.
Specifically, the mobile communication technology to which the SINR interval belongs is the same as the mobile communication technology to which the device type belongs; such as: when all SINR included in the SINR interval is 5G SINR, the mobile communication technology to which the device type belongs is 5G (that is, the device type is the device type of a 5G device).
And S105, simulating the scene map, and determining the cumulative distribution function of SINR of the specified area under the first mobile communication technology.
Optionally, the scene map includes a three-dimensional (3 Dimensions, 3D for short) map or a planning map; simulating a scene map, and determining a cumulative distribution function of SINRs of a specified area under the first mobile communication technology, as shown in fig. 11 and 12, including:
and S1050, simulating the 3D map, and determining the cumulative distribution function of SINR of the specified area under the first mobile communication technology.
Or,
s1051, simulating the planning graph, and determining the cumulative distribution function of SINR of the specified area under the first mobile communication technology;
wherein the cumulative distribution function comprises:
F(CDF)=a×SINR3+b×SINR2+c×SINR+d;
wherein, f (cdf) represents the probability of SINR occurrence of the user in the first mobile communication technology, SINR represents SINR in the first mobile communication technology, and a, b, c and d are all constants.
It should be noted that, in practical applications, determining the cumulative distribution function of SINR according to a 3D map or a planning map includes:
1. scene reproduction method
A 3D map with a specified accuracy (e.g., a 3D map with an accuracy of 2 × 2 m) may be obtained, after the 3D map is imported into simulation software (e.g., Atoll), base station parameters are configured, user point scattering simulation is performed, and then a CDF curve of SINR is calculated, as shown in fig. 13:
F(CDF)=a×SINR3+b×SINR2+c×SINR+d;
wherein a, b, c, d are all constants, SINR represents SINR under the first mobile communication technology, and f (cdf) is the probability of occurrence of the user at the SINR.
2. Scene hypothesis method
The method is suitable for scenes without base station construction, and under the condition that only the information of buildings and other buildings is known, the occupation ratio conditions of different types of penetration loss need to be calculated, and the specific situation is shown in table 2:
