For example, the base station corresponding to the user terminal includes a base station a and a base station B, after the network slice management apparatus receives the subscription template, the network slice management apparatus obtains the recent service conditions of the base station a and the base station B according to the service type in the subscription template, for example, obtains the slice deployment condition and the service condition of the last week or last several days, and determines whether a slice corresponding to the service type exists, and whether the usage rate of the slice is within a set range, if the usage rate of the slice is within the set range, the determination result is that the current slice can satisfy the service requirement; and if the utilization rate of the slice is not in the set range, judging that the current slice cannot meet the service requirement.
Step 905, when the current slice can meet the service requirement, sending a slice reservation request to a base station, wherein the slice reservation request comprises a user identifier, a service time, a service identifier and a slice type; and simultaneously returning a message of successful reservation to the user.
When the user accesses the base station, the base station verifies the user through the user identification, and when the user passes the verification, the base station accesses the terminal.
And 908, when the current slice cannot meet the service requirement, customizing the slice according to the slice requirement of the user.
And step 909, acquiring a user group with the same type of slicing requirements at preset time and preset position, arranging the slicing requirements of the user group, and generating the customized slices.
After step 910, step 906 is performed until the end.
