In the embodiment of the invention, the slice ordering interface of the display terminal displays the preset grid map, and a user selects the target grid of the service to be opened on the slice ordering interface of the display terminal. Illustratively, as shown in fig. 3, fig. 3 is a schematic diagram of a slicing ordering interface provided by an embodiment of the present invention. The user can directly select the target grid by using a mouse on the slice ordering interface, and the display terminal receives the target grid selected by the user and confirms the grid identification of the target grid. Or the user inputs the grid identification of the target grid in the slice ordering interface. The user enters service requirements, illustratively including data transfer rate and bandwidth, through the slice ordering interface. Illustratively, in the slice ordering interface, the selectable grid is displayed green and the non-selectable grid is set to red.

Illustratively, the base station information includes at least one of a base station equipment version, base station manufacturer information, and base station equipment model. All base stations to be opened contained in each grid can be determined according to the base station information of each target base station. Specifically, if the base station information of the base station is inquired in a pre-stored slice deployment base station list, the base station is used as a base station to be activated, wherein the slice deployment base station list stores the base station information of all base stations supporting the slice deployment function.

Illustratively, screening can be performed according to the basic data transmission function of the base station, and the base station with the data transmission function meeting the slice provisioning requirement of the base station is selected as the base station capable of slice deployment. Illustratively, each base station includes 3 cells, and then all cells to be deployed included in the grid can be determined according to all base stations to be deployed included in each grid, and network slice deployment is completed for users according to all cells to be deployed, so that end-to-end provisioning of rasterized slices is realized.

Specifically, the radio evaluation parameters of all cells included in all base stations to be deployed in each grid are obtained. Specifically, the wireless evaluation parameter of the cell is determined according to a wireless data model, wherein the wireless data model is a model which is constructed according to the characteristics of the cell and can evaluate the wireless signal strength of the cell. Illustratively, the expression for determining the cell radio estimation parameter according to the radio data model is shown in formula (1):
V＝t1*S+t2*W (1)
where V in formula (1) is a score of the wireless evaluation parameter, V is a decimal number greater than or equal to 0 and less than or equal to 1, W is a slicing capability evaluation value, S is a score, and the sum of t1 and t2 is 1.
The higher the score S of formula (1), the more the distance and signal strength of the cell to be evaluated satisfy the condition of slice deployment, and the calculation method of the score S is as shown in formula (2):
S＝L1*L2 (2)

illustratively, the preset threshold Q may be-105 dbm with a maximum value of 0.
W in formula (1) is an estimated slicing capability value, and specifically, the value of W is as shown in formula (5):
W＝w1+w2+w3 (5)
in formula (5), w1 represents a 5QI capability score of the cell, w2 represents an RB reservation capability score of the cell, and w3 represents a slice-specific carrier capability score of the cell, and specifically, when the base station supports 5QI, w1 takes a first percentage, and does not support a value of 0:

w2 ═ second percentage (number of reserved RB resources/theoretical maximum number of RB resources) (6)
The value of W3 is shown in equation (7):

Wherein, the values of the first percentage, the second percentage and the third percentage are limited according to specific conditions, and the rule is as follows: the sum of the first percentage, the second percentage and the third percentage is 1, and specifically, values of the first percentage, the second percentage and the third percentage can be set to be 1/3 according to requirements. When the bandwidth is 100M and the subcarrier spacing is 30kHZ, the theoretical maximum RB resource number is 263, the theoretical maximum carrier bandwidth is 100M, the configuration of the reserved RB resource number and the dedicated carrier bandwidth depends on the utilization rate of PRBs in busy hours of a cell, the reserved RB resource number can be 100, and the dedicated carrier bandwidth can be 10M.
