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 communication method and system converges a 5G communication system for supporting higher data rates beyond a 4G system with an IoT technology. The system and method may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Embodiments provide a scheme for efficiently operating an UP connection of a session in case where a terminal has a plurality of sessions in a mobile communication system, such as a 5G system, having a network structure in which an AMF for mobility management and an SMF for session management are separated from each other. A terminal (UE) can optimize a non-access stratum (NAS) signaling message, and can perform data transmission/reception with low latency.

Abstract: Disclosed are a signal transmitting method by a BS and a discovery method by a terminal to perform a WLAN discovery. The signal transmitting method by the BS includes: collecting information including beacon transmission periods and beacon transmission time of one or more WLAN Access Points (APs) within a cell range of the BS; generating grouping information in which beacon transmission time of the WLAN APs is mapped to a time area divided according to a grouping level from a reference time by using the collected information; and transmitting the grouping information to one or more reception terminals within cell range of the BS. Further, the discovery method by the terminal includes: receiving grouping information in which beacon transmission time of one or more WLAN Access Points (APs) is mapped to a time area divided according to a grouping level from a reference time; and discovering a WLAN AP only during a time to which the beacon transmission time is mapped according to the grouping information. Accordingly, the terminal can energy-efficiently discover a WLAN.
