Update Service Operation Towards hSMF Call Flow
The NF Service Consumer, such as vSMF, updates a PDU session in the hSMF. The NF Service Consumer also provides the hSMF with information that NF Service Consumer receives from vSMF in the N1 SM signalling from the UE. The NF Service Consumer uses the HTTP POST method to receive this information.
This section describes the Update service operation towards hSMF call flow.

Step | Description |

1 |
NF Service Consumer, such as vSMF, sends a POST request to modify a PDU session to the resource representing a PDU session resource in the hSMF. |
