Abstract: One disclosure of the present specification provides a method for a terminal creating a session, the terminal supporting next-generation mobile communication. The method may comprise the steps of: determining that a session must be newly created if the creation of a session is not included in a process of attaching to a core network of a next-generation mobile communication; on the basis of service type information, determining that the session being newly created needs to be always-on, or in other words, always-connected; and transmitting, to a control plane (CP) function node for managing the session, a connectivity request message including information indicating that the session that needs to be always-on, or in other words, always-connected, has been requested.

Abstract: Disclosed are a method and apparatus for monitoring User Equipment (UE) reachability in a wireless communication system. More specifically, a method for monitoring UE reachability in a wireless communication system comprises receiving, by a Mobile Management Entity (MME), a message for monitoring the UE reachability including UE reachability related indication from a Home Subscriber Server (HSS); and allocating, by the MME, an Active Time to a UE, wherein the UE reachability related indication is used for setting the Active Time of the UE and wherein the UE reachability indication is used for the UE to stay reachable so that downlink data that a server wants to transmit to the UE can be transmitted to the UE.
