1. A method performed by a session management function (SMF) in a mobile communication system, the method comprising:
obtaining information on a data forwarding in an evolved packet system (EPS)-to-5th generation system (5GS) handover;
generating N2 session management (SM) information which is transparent to an access and mobility management function (AMF), the N2 SM information indicating that the data forwarding is not possible or whether a direct forwarding path for the data forwarding is available, based on the information on the data forwarding; and
transmitting a message for providing a created SM context towards a new generation-radio access network (NG-RAN) node, wherein the N2 SM information is included in the message for providing the created SM context.
