Method for creating network service ns and related apparatus

A method for creating a network service (NS), comprising:

• receiving, by a network functions virtualization orchestrator (NFVO), a network service descriptor (NSD) query request sent by a management device, wherein the NSD query request is used to request information about an NSD from the NFVO;
• sending, by the NFVO, the information about the NSD to the management device, wherein the information about the NSD comprises information about a network service deployment flavour indicating a deployment flavour of a user for a network service;
• receiving, by the NFVO, an NS instantiation request sent by the management device based on the information about the network service deployment flavour;
• and
• creating, by the NFVO, an NS instance related to the NSD based on the NS instantiation request.

A management device, comprising:

• a processor,
• a bus,
• a transceiver, and
• a memory coupled to the memory to store instructions, which when executed by the processor, cause the processor to perform operations, the operations comprising:
• sending, by a management device, a network service descriptor (NSD) query request to a network functions virtualization orchestrator (NFVO), wherein the NSD query request is used to request information about an NSD from the NFVO;
• receiving, by the management device, the information about the NSD sent by the NFVO, wherein the information about the NSD comprises information about a network service deployment flavour indicating a deployment flavour of a user for a network service;
• and
• sending, by the management device, an NS instantiation request to the NFVO based on the information about the network service deployment flavour, to request the NFVO to create an NS instance related to the NSD.
