Abstract: The disclosure relates to a communication technique of converging a 5th generation (5G) communication system for supporting higher data rates after a 4th generation (4G) system with Internet of things (IoT), and a system therefor. The disclosure provides a method performed by a first network entity managing a packet data network (PDN) session in a wireless communication system supporting interworking between a first and second networks. The method comprises receiving subscription update information of a user equipment (UE) for which a PDN connection associated with a network slice is established in the second network, the network slice being subscribed in the first network, determining whether to release the PDN connection if the subscription update information includes information notifying that network slice related information of the UE is changed, and performing a release of the PDN connection associated with the network slice if the release of the PDN connection is determined.

Abstract: The disclosure relates to a method and a device for controlling a data rate in a network slice of a wireless communication system. A method for controlling a bit rate of a network slice by a session management function (SMF) device of a wireless communication system is provided. The method includes receiving a slice control policy information from a policy and charging function (PCF) device, transmitting, to a user plane function (UPF) device, a parameter for controlling each slice based on the received slice control information, and receiving, from the UPF device, a response signal for whether the transmitted parameter is acceptable.

Abstract: A method and an apparatus for installing a profile in a terminal including a universal integrated circuit card (UICC) corresponding to a smart card security module, which is inserted into a mobile communication terminal and then used are provided. More particularly, a method and an apparatus for remotely installing or removing mobile communication subscriber information in/from a profile of a terminal are provided. The terminal can remotely download the profile from a network server (subscription manager data preparation (SM-DP) or subscription manager secure routing (SM-SR)) without any change in a mobile network operator information technology (IT) system interface rather than downloading the profile of the terminal by the network server.

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.
