## Abstract

Provided is a Network Service (NS) descriptor management method performed by a Network Functions Virtualization Orchestrator (NFVO), the method including receiving a request message for a Hypertext Transfer Protocol (HTTP) method for a NS descriptor from an Operation Support System/Business Support System (OSS/BSS); and responding to the OSS/BSS with respect to the received request message. If the HTTP method for the NS descriptor is POST, a new NS descriptor is created, and if the HTTP method for the NS descriptor is GET, query information about a plurality of network descriptors is processed.

## Claims

### Claim 1

A Network Service (NS) descriptor management method performed by a Network Functions Virtualization Orchestrator (NFVO), the method comprising:
receiving a request message for a Hypertext Transfer Protocol (HTTP) method for an NS descriptor from an Operation Support System/Business Support System (OSS/BSS); and
responding to the OSS/BSS with respect to the received request message,
wherein, if the HTTP method for the NS descriptor is POST, a new NS descriptor is created, and if the HTTP method for the NS descriptor is GET, query information about a plurality of network descriptors is processed.

### Claim 2 (depends on 1)

The method of claim 1, wherein, in the created NS descriptor, NSDOperationalState is set as “DISABLED”, NSDUsageState is set as “NOT_IN_USE”, and NSDOnboardingState is set as “CREATED”.

### Claim 3

A method of managing each Network Service (NS) descriptor, performed by a Network Functions Virtualization Orchestrator (NFVO), the method comprising:
receiving a request message for a Hypertext Transfer Protocol (HTTP) method for each NS descriptor from an Operation Support System/Business Support System (OSS/BSS); and
responding to the OSS/BSS with respect to the received request message,
wherein, if the HTTP method for each NS descriptor is GET, information about each NS descriptor is read, if the HTTP method for each NS descriptor is PATCH, information about each network descriptor is modified, and if the HTTP method for each NS descriptor is DELETE, each NS descriptor is deleted.

### Claim 4 (depends on 3)

The method of claim 3, wherein, in the created NS descriptor, NSDOperationalState is set as “DISABLED”, NSDUsageState is set as “NOT_IN_USE”, and NSDOnboardingState is set as “CREATED”.

### Claim 5

A Network Service (NS) descriptor management method performed by a Network Functions Virtualization Orchestrator (NFVO), the method comprising:
receiving a POST request message from an Operation Support System/Business Support System (OSS/BSS);
creating an NS descriptor in response to the received POST request message; and
sending, to the OSS/BSS, a response message indicating that the NS descriptor is created.

### Claim 6 (depends on 5)

The method of claim 5, wherein, in the created NS descriptor, NSDOperationalState is set as “DISABLED, NSDUsageState is set as “NOT_IN_USE”, and SDOnboardingState is set as “CREATED”.

### Claim 7 (depends on 5)

The method of claim 5, wherein the POST request message includes a data structure of “CreateNsdInfoRequest” in a payload.
