Method and apparatus for creating network slice, and communications system

A system for creating a network slice, comprising a network slice management function (NSMF) entity and a network slice control function (NSCF) entity, wherein

• the NSMF entity comprises
• one or more first non-transitory memory storage comprising first instructions;
• and
• one or more first hardware processors in communication with the one or more first non-transitory memory storage, wherein the one or more first hardware processors execute the first instructions to send a service deployment command to the NSCF entity;
• and
• the NSCF entity comprises:
• one or more second non-transitory memory storage comprising second instructions;
• and
• one or more second hardware processors in communication with the one or more second non-transitory memory storage, wherein the one or more second hardware processors execute the second instructions to:
• receive the service deployment command sent by the NSMF entity;
• obtain, based on the service deployment command, a model, a policy, and one or more of:
• a service-related requirement parameter, a plan of a network slice, or registration information of a network function entity;
• generate a service configuration scheme of the network function entity based on the model and the policy of the network slice and the one or more of:
• the service-related requirement parameter, the registration information of the network function entity, or the plan of the network slice;
• and
• send the service configuration scheme to the network function entity.

An apparatus for creating a network slice, comprising:

• at least one processor and a non-transitory memory storing computer-executable instructions, wherein the computer-executable instructions, when executed by the at least one processor, instruct the at least one processor to:
• receive a service deployment command sent by a network slice management function (NSMF) entity;
• obtain, based on the service deployment command, a model, a policy, and one or more of:
• a service-related requirement parameter, a plan of a network slice, or registration information of a network function entity;
• generate a service configuration scheme of the network function entity based on the model and the policy of the network slice and the one or more of:
• the service-related requirement parameter, the registration information of the network function entity, or the plan of the network slice;
• and
• send the service configuration scheme to the network function entity.
