Abstract: User equipment may send a channel allocation request (hereinafter referred to as a first channel allocation request) to a network for transmission of data. When the transmission of data has backed off, the user equipment may send a channel allocation request (hereinafter referred to as a second channel allocation request) again for the transmission of data. At this time, the second channel allocation request may be transmitted to the network together with a priority raise request if a remaining timeframe Tremain of an upper timeframe T is smaller than a certain guard time.

Abstract: The present description discloses a method for performing network selection and traffic routing by a user equipment (UE). The method can comprise the steps of: a non-access stratum (NAS) of the UE receiving from a mobility management entity (MME) an indication, for wireless local area network (WLAN) offloadability for a first public data network (PDN) connection, and information about a network-based IP flow mobility (NBIFOM); the NAS of the UE determining whether or not a collision exists between the indication and information; the NAS of the UE deciding for a suspension of the NBIFOM on the basis of the existence of collision; and the NAS of the UE transmitting to a PDN gateway (P-GW) a message or information, notifying the suspension of the NBIFOM, on the basis of the decision for the suspension of the NBIFOM.

Abstract: A method for transmitting and receiving data in a wireless communication system, and a device therefor are disclosed. Particularly, a method for transmitting downlink data in a packet data network gateway (P-GW) in a wireless communication system can comprise the steps of: receiving, from an application server, downlink data in which an Internet protocol (IP) header including an IP address of a terminal is encapsulated; removing the IP header from the downlink data; and transmitting, to a serving gateway (S-GW), the downlink data from which the IP header is removed through a bearer identified by the IP address of the terminal, so as to transmit, to the terminal, the downlink data from which the IP header is removed.

Abstract: Disclosed are a serving node relocating method in a wireless communication system and a device for same. In detail, a method for relocating, by a first serving node, a serving node in a wireless communication system can include: receiving a tracking area update (TAU) request message from a terminal; transmitting an update location request to a home subscriber server (HSS), when the first serving node having received the TAU request message is different from a second serving node that is an old node; and transmitting an update location message to a service capability exposure function (SCEF), when the first serving node is different from the second serving node that is the old node and a connection for transmitting/receiving non-internet protocol (non-IP) data via the SCEF is configured in the terminal.

Abstract: A method of transmitting data and an eNB are disclosed. The method of transmitting data, which is received from a user equipment and transmitted to a network entity by an eNB, can include the steps of receiving a data packet of the user equipment from a first layer different from an IP layer of the eNB in the IP layer, checking whether or not the data packet corresponds to a data packet transmitted by the first layer using a header of the data packet, if the data packet corresponds to the data packet transmitted by the first layer, adding an IP header selected using a pre-stored mapping table to the data packet, delivering the data packet to which the IP header is added to a second layer corresponding to a lower layer, and transmitting the data packet to which the IP header is added to the network entity.
