Abstract: A first network device receives a request associated with data notification for a user equipment (UE). When the UE is in a mode in which communication of mobile terminated data is restricted and the first network device detects that the UE is in a non-allowed area, the first network device rejects the request unless the data notification is for a regulatory prioritized service.

Abstract: An embodiment of the present specification provides a method for acquiring an identifier of a visited public land mobile network (V-PLMN), in which a user equipment is roaming, by a proxy-call session control function (P-CSCF) of a home public land mobile network (H-PLMN). The method may comprise the steps of: receiving a register message from the user equipment; generating a first V-PLMN identifier on the basis of the register message; and transferring the first V-PLMN identifier to a home subscriber server (HSS), wherein whether the first V-PLMN identifier corresponds to an identifier of the V-PLMN which is serving the user equipment is verified by the HSS through comparison with a second V-PLMN identifier acquired in an initial attach procedure for an evolved packet core (EPC) of the user equipment.

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.

Abstract: One embodiment of the present specification provides a method for supporting a power saving mode in a wireless device. The method can comprise the steps of: transmitting a request message including a first active time value to a network entity, if a PSM is necessary; and receiving a rejection message for the request message from the network entity. Here, the rejection message includes the reason for rejection, and can include a second active time value determined by considering the first active time value. The method can comprise the steps of terminating the transmission procedure of the request message after receiving the reject message, and entering a PSM state on the basis of the second active time value.

Abstract: The present invention relates to a method and an apparatus for determining a path switch in a wireless communication system. Specifically, the present invention relates to a method for determining a path switch of a first network entity, the method comprising the steps of: receiving bearer setup information including a bearer type regarding at least one bearer; transmitting a path switch request to a second network entity on the basis of the bearer setup information; receiving a path switch response corresponding to the path switch request from the second network entity; and determining a path switch depending on whether the path switch response indicates admission of a default bearer.

Abstract: A disclosure of the present specification provides a method for transferring downlink data by a serving gateway (S-GW). The method may comprise the steps of: transmitting a downlink data notification (DDN) message to a mobility management entity (MME) and a serving general packet radio service (GPRS) supporting node (SGSN), when downlink data arrives at a wireless device in a state where an idle mode signaling reduction (ISR) is activated; receiving a message notifying of a DDN refusal from any one of the MME and SGSN when the wireless device, being in a power saving mode (PSM), cannot receive the downlink data; and transmitting a paging stop request message to any one of the MME and SGSN when the message indicating the refusal of the DDN is received.
