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 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: A method and a network node for supporting a connection between a User Equipment (UE) and a Machine Type Communication-interworking function (MTC-IWF) are discussed. The method according to an embodiment includes receiving, by the network node from the MTC-IWF, a mobile terminated (MT) message including a triggering payload by using a specific reference point; forwarding, by the network node to the UE, the trigger payload, if the trigger payload contains an application identifier which allows the network node and which distinguishes the MT message carrying device triggering information from any other type of MT message; and receiving a response message, which corresponds to the trigger payload, for initiating communication with the server, if the application identifier which allows the UE distinguishes the MT message carrying device triggering information from any other type of MT message.

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.

Abstract: The present invention provides a method for processing paging from a server managing mobility in a mobile communication network. The method comprises: receiving from a network node a notification with respect to downlink data to be relayed to user equipment; transmitting a paging signal with respect to the user equipment to one or more base stations; receiving a context request with respect to the user equipment from a different server; recognizing that the paging will fail if the context request with respect to the terminal is received before receiving a reply to the paging; relaying a context reply to the different server depending on the recognition; and transmitting a processing request message with respect to the downlink data to the network node.
