    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: A method of a central unit-control plane (CU-CP) included in a base station in a wireless communication system and an apparatus therefor are provided. The method includes identifying information on a radio link of at least one cell associated with the base station, transmitting, to a central unit-user plane (CU-UP), information indicating downlink transmission stop or resume of the CU-UP included in the base station based on the information on the radio link, and transmitting, to a distributed unit (DU), information indicating downlink transmission stop or resume of the DU based on the information on the radio link. The method relates to converging a 4th-Generation (4G) or a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4G system with a technology for Internet of Things (IoT), and may be applied to intelligent services based on the 5G communication technology and the IoT-related technology.

    Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure 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. The present disclosure further relates to a method by a session management function (SMF) in a network including a session that is established via a first user plane function (UPF). The method includes determining whether to change the first UPF to a second UPF, and transmitting, to a terminal via an access and mobility function (AMF), a first message including a maintain time of the session established via the first UPF, when the first UPF needs to be changed.

    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). According to various embodiments of the disclosure, an operating method of a user plane function (UPF) in a wireless communication system and an apparatus therefor are provided. The operating method includes receiving a first parameter for clock synchronization from a base station, and performing the clock synchronization with a neighboring network system using the received first parameter and a second parameter. The first parameter may include information relating to a link delay time between the neighboring network system and a network system comprising the UPF, and a residence time of a terminal, a base station and the UPF of the network system comprising the UPF, and the second parameter may include information relating to a backhaul delay time between the base station and the UPF.
