Abstract: Disclosed is a method of transmitting/receiving a signal in a Mobile Management Entity (MME) of a mobile communication system, the method comprising: transmitting a subscriber information request message including information of a UE, to a Home Subscriber Server (HSS); receiving, from the HSS, a response message which corresponds to the request message and includes an indicator indicating whether it is possible to perform traffic offloading using a Wireless Local Area Network (WLAN) with regard to an Access Point Name (APN) connection or a Packet Data Network (PDN) connection of the UE; determining whether it is possible to perform the traffic offloading using the WLAN, on the basis of at least one of information included in the received response message and information configured in the MME; and; and transmitting, to the UE, a message including information on whether it is possible to perform the traffic offloading using the WLAN. A communication method according to an embodiment of the present specification can generate one or more PDN connections with regard to one APN when the UE accesses a PDN through the WLAN. Further, the communication method according to the present invention can effectively be subjected to a traffic offloading control by the eNB even when the UE is roaming.

Abstract: The present disclosure relates to a 5G or pre-5G communication system for supporting a data transmission rate higher than that of a 4G communication system such as LTE. According to one embodiment of the present invention, the present invention comprises the steps of: an access and mobility management function (AMF) of a 5G core network determining whether a terminal has moved to an area in which packet transmission/reception is possible, or an area in which packet transmission/reception is impossible; transmitting a message including information on the determination result to a session management function (SMF); and transmitting a response message including information associated with a change in the state of a session to the terminal. In addition, the present invention relates to a method and a device for blocking or allowing the transmission/reception of a packet transmission session (PDU session) according to the position of a terminal in a 5G system. In a 5G system, a local area data network service by which a packet session is valid only in a specific area will be supported, and a method is required for allowing the transmission of a packet of a session only in an area that can be divided into a cell or a tracking area. Additionally, in a 5G system, an allowed area in which the transmission/reception of a packet of a session according to each position of a terminal is allowed, and a non-allowed area in which same is not allowed are present, and thus packet transmission may be allowed or not according to area. In order to provide such service, the present invention provides a procedure whereby the state of a session is defined in a packet transmission non-allowed area, and a change in the state of the session occurs when moving from a packet transmission-allowed area to the non-allowed area.

Abstract: The present invention defines signaling required for separating a network entity (NE) responsible for mobility management (MM) and session management (SM), which are main function of a control plane (CP) in a next generation (NextGen) mobile communication system, and presents a basic procedure for providing mobile communication services including the signaling. Therefore, complexity of core equipment responsible for the CP is reduced in order to implement a network slice function and provide various levels of mobility, and an effect of minimizing a signaling load therebetween can be obtain. In addition, it is possible to efficiently manage the resources of a base station (radio access network (RAN)) and a user plane network entity (UP NF).

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 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). A method for preventing a loss of data packets of a transmission end is provided. The method includes performing a path switching operation, receiving, from a reception end, a switching status report that includes information related to the data packets that were not received by the reception end, and retransmitting the data packets that were not received by the reception end, where the path switching operation is an operation of switching a data transmission path from a first communication system to a second communication system or from the second communication system to the first communication system, and where the first communication system is a fourth generation (4G) communication system, and the second communication system is a fifth generation (5G) communication system that uses a millimeter-wave (mm-wave) band.

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.
