    Abstract: The present invention relates to a method and an apparatus for a first mobility management entity (MME) to activate a terminal in a wireless communication system. According to the present invention, it is possible to provide a method and an apparatus of receiving a notification message transmitted from a service gateway (S-GW) to a terminal managed by the first mobility management entity, for notifying an occurrence of a first downlink data; determining whether there exists at least one terminal linked with the terminal on a basis of a first context information of the terminal; and performing a paging procedure for transitioning the terminal and the at least one terminal to a connection state when the at least one terminal linked to the terminal exists.

    Abstract: A method for performing a security procedure by a terminal in a wireless communication system, and an apparatus thereof. The method includes transmitting a first access request message for accessing a first network of a core network to a first radio access network (RAN) node, performing an authentication procedure for mutual authentication with a node performing an authentication server function (AUSF) of the core network, generating a common key commonly used in one or more networks included in the core network based on an authentication vector obtained through the mutual authentication procedure, generating a first base key of the first network based on the common key and a network code corresponding to a type of the first network, and receiving an access accept message indicating an access accept of the first network from the first RAN node.
