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: 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: 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.

Abstract: The present invention relates to a mobile communication system, and more particularly relates to a method for transmitting a small-sized control signal (also known as “small data”) using a control plane in a MTC (machine-type communication) service in a mobile communication system. In the present invention, MTC data is encapsulated in an existing control procedure or control message or the like, on a control signal, without performing packet data bearer setup, and the control signal having the encapsulated MTC data is sent between a network and a terminal, thereby optimizing network resource efficiency and reducing the wireless channel load.

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.
