    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: The present invention relates to a communication method for merging, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system, and a system therefor. The present invention can be applied to an intelligent service (for example, smart home, smart building, smart city, smart car or connected car, healthcare, digital education, retail, security and safety related services, and the like) on the basis of a 5G communication technology and an IoT-related technology. The present invention provides a method by which a terminal requests authentication from a 3rd party server comprises the steps of: transmitting, to a common control function providing device (common control plane network function serving unit), a service request message including a tenant ID and a slice type provided by an application related to the 3rd party server; receiving a service response message including information on the limited data session from the network slice instance management device when a network slice instance management device (network slice instance unit) selected by the common function providing device generates a limited data session (limited packet data unit session) for authentication between the terminal and the 3rd party server on the basis of the service request message; and transmitting an authentication request message requesting authentication of the terminal through the limited data session to the 3rd party server on the basis of the service response message.

    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.
