1. A method for Xn handover of a multicast/broadcast service (MBS) by a session management function (SMF) in a mobile communication system, the method comprising:
receiving, from a target next generation radio access network (NG-RAN) node through an access and mobility management function (AMF), a first message including information on whether the target NG-RAN node supports the MBS;
determining an individual delivery method for MBS data, in case that the target NG-RAN node does not support the MBS based on the information received from the target NG-RAN node; and
performing an establishment of individual MBS data delivery, wherein the information on whether the target NG-RAN node supports the MBS is N2 session management (SM) information received from the target NG-RAN node to the SMF via the AMF.
