Abstract: A method for adjusting a timer value for a device includes determining, by a home subscribing server (HSS), a timer value for a routing area update (RAU) or a tracking area update (TAU) based on a maximum time period, wherein the timer value for the RAU or the TAU is determined to be a smaller value than the maximum time period, wherein the maximum time period is related to a loss of a connectivity indicating the device is no longer possible to be signaled, and delivering, by the HSS, information regarding the determined timer value for the RAU or the TAU to a Mobility Management Entity (MME)/Serving General Packet Radio Service (GPRS) Supporting Node (SGSN).

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: 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: The present description discloses a service request method. The service request method comprises the steps of: increasing a counter whenever a service request message has been transmitted multiple times to a first network node in a first public land mobile network (PLMN), but an acceptance message has not been received by the time a first timer expires; comparing the counter value with an upper threshold value; and running a second timer if the counter value is equal to or greater than the upper threshold value, wherein the transmission of the service request message can be prevented until the second timer expires.

Abstract: Disclosed are a serving node relocating method in a wireless communication system and a device for same. In detail, a method for relocating, by a first serving node, a serving node in a wireless communication system can include: receiving a tracking area update (TAU) request message from a terminal; transmitting an update location request to a home subscriber server (HSS), when the first serving node having received the TAU request message is different from a second serving node that is an old node; and transmitting an update location message to a service capability exposure function (SCEF), when the first serving node is different from the second serving node that is the old node and a connection for transmitting/receiving non-internet protocol (non-IP) data via the SCEF is configured in the terminal.

Abstract: One embodiment of the present specification provides a method for managing subscriber information to respond to a network failure in a home subscriber server (HSS). The method can comprise the steps of: receiving a packet data network (PDN) failure indication; updating subscriber information related to a PDN on the basis of the PDN failure indication; and transmitting a message that indicates the update of the subscriber information.

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: A method is provided for determining an access based on policy. A user equipment (UE) receives a plurality of policies including a wireless local area network (WLAN) selection rule from a plurality of access network discovery and selection functions (ANDSFs) at a plurality of public land mobile networks (PLMNs). The UE receives specific information from at least one PLMN of the plurality of PLMNs. The UE selects a policy among the plurality of policies based on the specific information if there is no user configuration The selected policy is used to select a WLAN access. The plurality of PLMNs include a home PLMN (H-PLMN) and a visited PLMN (V-PLMN).
