Section: 13.4.1.1A Service access authorization in interconnect scenarios
Content: In the inter-PLMN interconnect scenario, OAuth 2.0 roles are as follows: a. The NF Service Consumer's Network Repository Function (cNRF) shall be the OAuth 2.0 Authorization server for the PLMN of the NF Service Consumer (cPLMN) and authenticates the NF Service Consumer. b. The NF Service Producer's Network Repository Function (pNRF) shall be OAuth 2.0 Authorization server for the PLMN of the NF Service Producer (pPLMN) and generates the access token. c. The NF Service Consumer in the cPLMN shall be the OAuth 2.0 client. d. The NF Service Producer in the pPLMN shall be the OAuth 2.0 resource server. As an example of the inter-PLMN interconnect use case, service access authorization in the roaming scenario where the service consumer NF is located in the visiting PLMN and the service producer NF is located in the home PLMN is specified in clause 13.4.1.2.
