1. An access and mobility management Function, AMF, node configured to enable at least one congestion control process, the AMF node comprising:
processing circuitry configured to:
receive a first message including a modification request message, the first message including a first indication indicating that the modification request message is exempt from the at least one congestion control process, the first indication being provided by a predefined request type included in the modification request message;
forward the modification request message to a session management function, SMF, with a second indication indicating the at least one congestion control process is enabled at the AMF node; and
receive, from the SMF, a notification of a determination of whether the first message is accepted, the determination being one of:
the message being accepted based on the request type being for reporting Data Off status change; and
rejected based on the request type being not for reporting Data Off status change.
