Abstract: The present invention relates to a communication system and method for merging, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system. The present invention provides a system and method by which a user equipment (UE) transmits, to an access and mobility management function (AMF), a first message including information related to a network slice in a first authentication, and receives, from the AMF, a third message including a result of a second authentication, wherein whether to require the second authentication is determined by the AMF based on the information and subscription information, and wherein the second authentication between the UE and a server is triggered based on the determination.

Abstract: The disclosure relates to a method and apparatus for providing an AM policy for a UE in a wireless communication system. The disclosure is applicable to apply a consistent policy to a UE in a system in which 4G and 5G networks co-exist. According to the disclosure, a BS in a wireless communication system may include a transceiver, and at least one controller coupled to the transceiver. The at least one controller may be configured to determine handover for a UE based on a communication state of the UE, transmit a handover request message for the UE to an AMF, receive a handover command for the UE from the AMF in response to transmitting the handover request message, and perform a handover procedure with the UE. The handover request message may include information related to a rule used to select a network and a frequency applied to the UE.

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.
