Abstract
A method implemented in an access and mobility management function, AMF, node that implements at least one congestion control process is provided. A message including a first indication that the message is exempt from the at least one congestion control process is received by a UE. The message is forwarded to the SMF either with the exempt indication or, if this is missing, an indication that the AMF applies a congestion control. The SMF, only when receiving the forwarded message with the additional information inserted by the AMF, carries out a validation of the message of the UE, thus preventing that a UE tags a message to be exempted from congestion control, when it should be not be exempt.
