摘要： 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.

摘要： 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).

摘要： 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.
