Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The embodiments in the present disclosure allow to transfer remaining data between different base stations in a dual-registration interworking process, which provides terminal mobility between 4G and 5G networks without a data loss. Further, it provides the terminal mobility with no data loss without changing 5G and 4G base station implementation through addition of a simple function of new equipment, such as SMF and UPF. Further, it supports different QoS and forwarding path units in the 5G/4G networks without changing 5G and 4G base station functions. Further, it exempts additional function implementation costs for re-ordering in a terminal and a network through in-order delivery of packets to the terminal without changing the packet order during 4G-5G network movement.

Abstract: A method performed by an application function (AF) in a wireless communication system is provided. The method includes receiving, from a session management function (SMIF), a late notification message indicating a change of a data network access identifier (DNAI), identifying whether an AF change is needed based on the late notification message, and transmitting, to the SMIF, a response message including information for change to a target AF for a target DNAI based on a result of identifying that the AF change is needed.
