context: (e.g., username/password) are based on MSGin5G service provider policy. The method chosen by the service provider is neither defined nor limited to the example (username/password) provided in this solution. Step 5: SIM-S verifies the username and password and authenticates the UE. Step 6: SIM-S sends an OpenID Connect Authentication Response to SIM-C containing an authorization code (AuthCode). Step 7: SIM-C sends an OpenID Connect Token Request to the SIM-S, passing the AuthCode. Step 8: SIM-S sends an OpenID Connect Token Response to the UE containing an access token (each uniquely identifies the user of the MSGin5G service). The access token is used by the 5GMSGS UE client to authorize the communication between the 5GMSGS UE client and the MSGin5G server. The access token and ID-token format is the same as the format defined in TS 33.434, Annex A.2.1 and A.2.2. Step 9: 5GMSGS UE client gets the access token from the SIM-C. Step 10: As a procedure for SEAL key management, key
description: The SEAL Identity Management Server (SIM-S) is a network function responsible for managing identities and authenticating users in the 5G network. It verifies usernames and passwords, sends authentication responses, and issues access tokens to authorize communication between the UE client and the MSGin5G server.
explanation: SIM-S is classified as a Network Function based on its role in managing user identities, authenticating users, and issuing access tokens for secure communication within the network, as described in the context from 3GPP TS 33.862.
