METHODS AND NODES FOR IN-ADVANCE QOS PREDICTION NOTIFICATION

摘要

An SMF node (140) and a method (900) therein are described. The SMF node (140) is configured to receive a request for an IQN and receive IQN distribution policy; determine that QoS of the PDU session handled by the SMF node (140) is predicted to be affected according to the request and to the distribution policy; and send the IQN to a recipient associated with the PDU session in a NAS message when the recipient is a UE (110), or a SBA message when the recipient is an AF or another NF. Also, a Network Data Analytics Function Node (150) and a method (1000) therein, and a UE (110) and a method (1100) therein are disclosed.
