The eMBB performs guarantee and performance enhancement of communication service through a large bandwidth and MU-User Multiple-Input Multiple-Output (MU-MIMO) technology, and is generally used for carrying services such as AR (Augmented Reality ), VR (Virtual Reality), high-definition video, high-definition live broadcast and the like; the uRLLC is used for guaranteeing the communication quality of the service with higher time delay requirement, such as remote operation and fine control; mctc is generated due to the requirement of massive user access capability, and is mainly used for solving the problem that the traditional mobile communication cannot well support the application of the internet of things and the vertical industry, and is mainly used for application scenes targeting sensing and data acquisition, such as smart cities, environment monitoring, smart home and forest fire prevention, and the like, and the scenes have the characteristics of small data packets, low power consumption, massive connection and the like.

Such as: and acquiring a scene map and configuration parameters of the access network equipment 1 to be built, and guaranteeing the bandwidth of the preset service which can be initiated by the terminal 2.

The following describes the method for evaluating the number of accessible users provided in the embodiment of the present invention, taking the device for evaluating the number of accessible users as a server 3 and the device for planning access network as a planning base station in connection with the communication system shown in fig. 1.

As shown in fig. 2, the method for evaluating the number of accessible users includes the following steps S11-S15:

s11, the server 3 acquires a scene map and configuration parameters of the planned base station, and service parameters and rated service duty ratio of each service in at least one service to be accessed by the planned base station. Wherein the configuration parameters include device type and access network device parameters.

In one implementation, the server 3 determines whether the number of accessible users of the proposed base station can be evaluated by analyzing the nominal service duty cycle of each of the at least one service to which the proposed base station is to access.

Specifically, by collecting the occupation proportion of different services in the to-be-constructed area (i.e. the coverage area of the to-be-constructed base station), by defining the occupation proportion of typical services in the to-be-constructed area, several types with the largest occupation proportion of the services can be selected for analysis, and the services with less occupation proportion, such as TOP3, are abandoned as the effective occupation proportion of the services. The service duty ratio is the service duty ratio of extracting the actual service duty ratio according to the user's requirement as shown in table 1 or the service duty ratio of the typical positions (good point, middle point and bad point) as shown in table 2. Two services are:

Table 1 actual traffic duty cycle

Service class	A	B	C
				Service duty cycle	P _A	P _B	P _C

Table 2 traffic duty cycle for typical locations

Service class	A	B	C
				Good point service duty cycle	P ^G	P ^G	P ^G
Service duty cycle of midpoint	P ^M	P ^M	P ^M
				Service duty cycle of difference point	P ^B	P ^B	P ^B

In practical applications, if the service duty ratio of the typical location cannot be provided, the service duty ratio of the typical location (such as the good point, the middle point, and the bad point) may be represented by the actual service duty ratio. Wherein the actual service ratio of any one of the service in the first section (also called good point), the service in the second section (also called middle point) and the service in the third section (also called difference point) satisfies the following formula:

P＝P ^G +P ^M +P ^B 。

when P is greater than or equal to the preset threshold, the determination server 3 may evaluate the number of accessible users of the proposed base station. For example, the preset threshold may be 0.6.

In one implementation, the access network device parameters include one or more of the following: simulation scene, inter-station Distance (english full name: inter-Site Distance, abbreviated as: ISD), number of sites (total number of surrounding base stations), base station antenna height, channel model, subcarrier spacing, traffic model, number of users per sector, user distribution, indoor and outdoor user distribution (different penetration loss duty ratio), user mobility, frequency band, system bandwidth, physical resource block (english full: physical Resource Block, abbreviated PRB), frame structure, evolved node B (abbreviated eNB) transmit power, number of antenna elements, number of antenna element radiation pattern, number of transmit/receive units, base station noise figure, antenna downtilt, UE antenna height, minimum Distance between base station and user, number of UE receive antennas, UE noise figure, number of UE transmit antennas, UE transmit power, downlink Single user Multiple-Input Multiple-Output antenna system (abbreviated DL SU-MIMO) maximum number of streams, downlink Multi-user Multiple-Input Multiple-Output antenna system (abbreviated DL MU-MIMO) maximum number of streams, uplink Single user Multiple-Input Multiple-Output antenna system (abbreviated DL-MU-MIMO) maximum number of streams, uplink Single user Multiple-Input Multiple-Output Multiple antenna system (abbreviated DL-MU-MIMO) maximum number of streams, uplink Multiple-MIMO maximum number of streams, uplink Multiple-Output Multiple-Output antenna system (hereinafter abbreviated DL-MIMO) maximum number of streams, uplink Multiple-Output system (SU-Multiple-Output system, uplink Multiple-Output system (SU-Multiple, one or more of a propagation model and a handover margin.

S12, the server 3 carries out simulation according to the scene map, the equipment type and the access network equipment parameters, and determines the simulation point duty ratio in the intervals of different signal to interference plus noise ratios (Signal to Interference plus Noise Ratio, SINR).

In one implementation, the device types include 6 transceiver components (transmitter and receiver, TR for short), 8TR, 16TR, 32TR, and 64TR.

In one implementation, the scene map includes a three-dimensional (3D) map and a layout diagram.

It should be noted that, in practical application, the server 3 performs simulation according to the scene map, the device type and the access network device parameter, and determining the simulation point duty ratio in different SINR intervals includes:

1. scene reproduction method

The server 3 obtains a 3D map with specified precision (for example, a 3D map with the precision of 2 m×2 m), and after importing the 3D map into simulation software (for example, atoll), configures device type and access network device parameters, performs user point scattering simulation, and then determines SINR of at least one simulation point.

2. Scene false seeking method

The method is suitable for a scene without base station construction, and under the condition that only buildings and other building information (such as a planning chart) are known, the duty ratio conditions of different types of penetration loss need to be calculated, and the specific conditions are shown in a table 3:

TABLE 3 Table 3

Type of penetration loss	Penetration loss duty cycle
		Outdoor (outoor)
Indoor low penetration loss
		Indoor high penetration loss

Then, the server 3 performs simulation using system simulation software (e.g., matlab, etc.) based on the penetration loss ratio, the device type, and the access network device parameters, performs user spreading point simulation, and then determines SINR of at least one simulation point. The penetration loss ratio is determined by scene construction by different penetration loss models defined in 38.901 standard.

Then, according to the SINR of at least one simulation point, the simulation point duty ratio in different SINR intervals is determined.

Illustratively, the different SINR intervals may be (- + -infinity, 4.5] (4.5, 12.5), and (12.5, + -infinity), then the respective duty cycles of the simulation points within the different SINR intervals are:

wherein ,P_G The total number of simulation points representing SINR greater than 12.5dB is N _all The ratio of P _M Representing that SINR is less than or equal to 12.5dB and that the total number of emulation points with SINR greater than 4.5dB is N _all The ratio of P _B The total number of simulation points representing SINR less than 4.5dB is N _all The ratio of N _all The total number of simulation points when the server 3 performs the simulation according to the scene map, the device type and the access network device parameters is represented.

S13, the server 3 determines actual throughput of different SINR intervals according to the simulation point duty ratio of the different SINR intervals and rated throughput of the different SINR intervals corresponding to the equipment type.

In one possible way, the actual throughput of the different SINR intervals satisfies the following equation:

/>

The nominal downlink throughput of the proposed base station of the device type tpye in the third interval is indicated, and the type may be any one of 6TR, 8TR, 16TR, 32TR and 64 TR.

S14, the server 3 determines the actual service duty ratio of each service in each SINR interval according to the rated service duty ratio of each service.

In one embodiment, the actual traffic ratio satisfies the following formula:

P＝P ^G +P ^M +P ^B ；

S15, the server 3 determines the rated number of users of the planned base station which can access the preset service according to the duty ratio of the simulation points in different SINR intervals, the actual throughput of the different SINR intervals and the actual service duty ratio of each service in each SINR interval. The preset service is a service in at least one service.

Based on the above technical solution, in the case that the proposed base station is to deploy a plurality of different types of services to be deployed, the embodiment of the present application first obtains a scene map and configuration parameters of the proposed base station, and service parameters and rated service duty ratio of each service in at least one service to be accessed by the proposed base station. And then, simulating according to the scene map, the equipment type and the access network equipment parameters, and determining the simulation point duty ratio in different SINR intervals. Determining actual throughput of different SINR intervals according to the simulated point duty ratio in the different SINR intervals and rated throughput in the different SINR intervals corresponding to the equipment type; and determining the actual service duty ratio of each service in each SINR interval according to the rated service duty ratio of each service. And finally, determining the rated user number of the preset service accessible to the planned base station according to the actual throughput of different SINR intervals and the actual service duty ratio of each service in each SINR interval.

In an implementation manner, referring to fig. 2, as shown in fig. 3, the method for evaluating the number of accessible users according to the embodiment of the present invention further includes S16 and S17.

S16, the server 3 carries out typical scene simulation according to typical scene simulation parameters corresponding to the equipment type, and determines second SINR and throughput acquired at least one typical position. The typical scene simulation data are obtained by simulating a typical scene under the first mobile communication technology, wherein the typical scene comprises at least one of a dense urban area, a suburban area and an open area.

Specifically, typical scene simulation parameters are second SINR and throughput acquired at different sampling points in a laboratory environment. The throughput may be, for example, an average throughput.

In practical applications, when a single terminal and a plurality of terminals are placed at a single sampling point, the corresponding SINR and throughput data will change. Therefore, in order to more accurately calculate the SINR and average throughput of a single sampling point, a 4-terminal placement for each sampling point is described herein as an example.

First, different sampling points are selected. Then, more than 4 (including 4) terminals are placed at each sampling point, and SINR collected by each terminal is collected, and uplink throughput and downlink throughput of user datagram protocol (User Datagram Protocol, UDP) service are performed. The reason for choosing to place 4 UEs here is that the throughput of a base station when fully loaded can be simulated when placing 4 UEs, since one UE supports at most 4 downlink and each base station supports 16 downlink simultaneously. Of course, in practical application, when the maximum number of uplink times supported by the base station is N and the maximum number of uplink times supported by the UE is N, the number of UEs supported by the base station when the base station is fully loaded is

When the maximum number of downlink times supported by the base station is N and the maximum number of downlink times supported by the UE is N, the number of UE supported by the base station when fully loaded is +.>

For example, assuming 6 points of SINR 22, SINR 18, SINR 9, SINR 6, SINR 0 and SINR-2 are sampling points, the recorded data is shown in Table 4.

The point a, the point b, the point c and the point d are respectively located on the boundary of the same concentric circle o, and the SINR of each UE located on the same concentric circle is the same. Specifically, the correlation degree between the UEs can be placed according to the correlation degree actually required; for example, the correlation between UE-a and UE-b is illustrated as an example, and the calculation manner of the correlation between other UEs is the same as that of the correlation between UE-a and UE-b, which is not described here again.

Specifically, the correlation is equal to an included angle formed by connecting any two UE with the base station antenna respectively; such as: an included angle theta is formed by a connecting line of the point a in the horizontal direction and the circle center o (representing the position of the base station antenna) and a connecting line of the point b in the horizontal direction and the circle center o; or an included angle theta is formed by a connecting line of the point d in the horizontal direction and the circle center o (representing the position of the base station antenna) and a connecting line of the point b in the horizontal direction and the circle center o; or, as shown in fig. 5, the included angle θ is formed by the connection line between the point a and the circle center o in the vertical direction and the connection line between the point b and the circle center o in the horizontal direction.

Specifically, mode 1, mode 2, mode 3, mode 4, mode 5, and mode 6 each represent that 4 UEs are simultaneously placed at positions corresponding to the same SINR.

By measuring the corresponding throughput for SINR 22, SINR 18, SINR 9, SINR 6, SINR 0 and SINR-2 for each correlation, the SINR-average throughput curve for the same correlation is fitted. As shown in fig. 6 (SINR on the abscissa and average throughput on the ordinate), an average throughput curve of SINR at correlation of 0.3 is given; wherein the average throughput of each point is equal to the average of the throughput of each UE at the same SINR.

The SINR-average throughput curves with correlation of 0.3, 0.5 and 0.8 are finally obtained, as shown in the following formula:

T _0.3SINR (SINR)＝f ₁ (SINR)；

T _0.5SINR (SINR)＝f ₂ (SINR)；

T _0.8SINR (SINR)＝f ₃ (SINR)。

based on the formula of single correlation, calculating average throughput under single SINR:

wherein ,n₁ The number of the selected correlation degrees; since the invention selects only three correlations of 0.3, 0.5 and 0.8, n is ₁ Equal to 3.

Illustratively, the descriptions are given by taking SINR of 22, SINR of 18, SINR of 9, SINR of 6, SINR of 0, and SINR of-2, and correlation degrees of 0.3, 0.5, and 0.8 as examples:

average throughput of SINR 22

The average throughput for SINR 18, SINR 9, SINR 6, SINR 0 and SINR-2 is calculated in the same manner as the average throughput for SINR 22, and will not be described here.

For different SINR-average throughput values, calculating average throughput T in a certain SINR interval _{_SINR_gap} ：

Where n_gap is the total number of typical points contained in the SINR interval.

Illustratively, the SINR intervals (- ++4.5 ], (4.5, 12.5), and (12.5, ++infinity) are illustrated as shown in table 5, wherein the points with SINR of-2, -1, 0, 1, 2, 3, and 4 are selected as typical points, respectively, when n_gap is equal to 10, and the points with SINR of 5, 6, 7, 8, 9, 10, 11, and 12 are selected as typical points, when n_gap is equal to 8, and SINR of [12.5, 22.5] are selected as typical points, when n_gap is equal to 10, when n_gap is equal to 8, respectively.
