Abstract
Provided in one embodiment of the present specification is a method by which an NG-RAN node performs communication related to a multicast. The method may comprise the steps of: receiving, from an AMF, a UE context release command message related to a first UE; determining that the first UE moves from a 5GS to an EPS, on the basis of the reception of the UE context release command message; and removing, from a context related to a multicast session, information related to the first UE.
