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: 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.
