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.

Abstract: The present invention relates to a method and a device by which first user equipment (UE) that is located out of the range of a group communication service determines a relay through a proximity service (ProSe) in a wireless communication system. Particularly, the method comprises the steps of: receiving traffic transmitted by second UE which already relays group communication; determining whether the traffic is information bound to group communication; determining relay UE by using a discovery procedure for a relay for the group communication, when the traffic is not recognized as the information bound to the group communication; and determining the second UE as the relay UE for the group communication, when the traffic is recognized as the information bound to the group communication.
