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 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: The present disclosure relates to a communication method and system for converging a 5 th-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.A method for a base station to perform communication in a wireless communication system includes transmitting an interface setup request message related to tracking area information to at least one mobility management entity (MME) in a first MME pool. The method includes identifying whether an interface setup response message related to the tracking area information is received from the at least one MME in the first MME pool, and storing mapping information between the tracking area information and the first MME pool if the interface setup response message is received.
