    Abstract: The disclosure relates to a communication method and a 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 disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as a smart home, a smart building, a smart city, a smart car, a connected car, health care, digital education, smart retail, security and safety services. A user equipment (UE) is provided. The UE includes a transceiver, and at least one processor, wherein the at least one processor controls the transceiver to transmit a first message requesting an event to an opening mediation server, receive event-related information from the opening mediation server in response to the first message, transmit a second message requesting an event to a profile providing server based on the event-related information, and receive information related to event processing from the profile providing server in response to the second message.

    Abstract: The disclosure relates to 5G or 6G communication systems to support a higher data rate after 4G communication systems, e.g., LTE. The disclosure provides a method performed by a user equipment (UE) in a wireless communication system, the method comprising: receiving, by a modem from an embedded universal integrated circuit card (eUICC), a first message including at least one of information related to whether eUICC functionality is supported and information related to whether multiple enabled profiles (MEPs) are supported; and determining, by the modem, to operate with an MEP function based on at least one of the received information related to whether the eUICC functionality is supported and information related to whether the MEPs are supported. Further, various embodiments of the disclosure provide a method and device for providing a dual-SIM function even in a UE equipped with a single eUICC in a wireless communication system.

    IPC: H04W8/18

    Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method and an apparatus for providing a dual subscriber identity module (SIM) function even in a terminal with a single embedded universal integrated circuit card (eUICC) mounted are provided. A method and an apparatus for installing, activating, and managing a plurality of profiles are provided, so that even a terminal with a single eUICC mounted may provide a dual SIM function in a communication system. The method includes the following embodiments to achieve the foregoing aspect, a method in which an eUICC receives a command involving a profile state change from a local profile assistant (LPA), registers a proactive command, and notifies a modem of logical interface information for obtaining the proactive command, a method in which the eUICC determines whether to perform polling on a specific logical interface by combining predetermined information, such as the logical interface information received from the mode, the state of a logical interface collected and possessed by the modem, and the number of an interface on which a corresponding message is received, a method in which the modem receives and processes the proactive command by performing polling on the logical interface, and a method in which the eUICC receives the result of processing the proactive command and completely changes the state of a profile connected to the logical interface. Further, a method in which the eUICC selectively configures a REFRESH message depending on whether the modem supports multiple enabled profiles (MEP) and divisively transmits the message to the modem when the eUICC receives a request for eUICC memory resetting or a profile state change in the terminal may be provided.
