Abstract: One disclosure of the present specification provides a method in which an access and mobility management function (AMF) node processes a packet data unit (PDU) session establishment procedure. The method may include a step of determining whether to reject a PDU session establishment request or not. Here, the determining step may be performed when the PDU session establishment request includes an identifier of an existing PDU session. On the basis of the identifier of the existing PDU session, an identifier of a session management function (SMF) node may be obtained. If it is determined that the SMF node and the AMF node both belong to the same public land mobile network (PLMN) on the basis of the identifier of the SMF node, the PDU session establishment request can be accepted. If it is determined that the SMF node and the AMF node both belong to a home PLMN (HPLMN) on the basis of the identifier of the SMF node, the PDU session establishment request can be accepted.

Abstract: Disclosed are a method and appraraus 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.

Abstract: A disclosure of the present invention provides a method for supporting a power saving mode (PSM) in a radio device. According to the method, the radio device may transmit a first message including a first activation time value to a network entity when the radio device requires the PSM. Then, the radio device may receive a second message including a second activation time value from the network entity. The radio device may enter a PSM state on the basis of the second activation time value. When it is necessary to stop the PSM or change the second activation time, the radio device may transmit a third message at the very time point.
