Claim 0:
1. A method for enabling a network data analytics function (NWDAF) to transmit and receive signals in a wireless communication system comprising:
receiving, by the NWDAF, a notification message based on a change of a user plane congestion status from operations and maintenance (OAM); and
transmitting, by the NWDAF, a user plane congestion analytics notification based on the notification message to a V2X application server through a network exposure function (NEF),
wherein the change of the user plane congestion status is determined based on at least one information including specific information indicating whether a QoS Notification Control (QNC) notification has been transmitted; and
wherein the specific information indicating whether the QNC notification has been transmitted is determined based on a counter value that increases when an NG-RAN transmits ‘GFBR cannot be fulfilled/guaranteed’ to a session management function (SMF) and decreases when the NG-RAN transmits ‘GFBR cannot be fulfilled/guaranteed’ to the SMF.
