摘要： 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.

摘要： A method for managing an area of a terminal in a wireless communication system and an apparatus therefor are disclosed. Specifically, a method for performing, by a terminal, location area update in a wireless communication system may comprise the steps of: transmitting, to a network node, a first request message including an additional cell list comprising one or more neighboring cells of a serving cell of the terminal; receiving, from the network node, a first accept message including information indicating acceptance of the use of the additional cell list; and, when a changed serving cell of the terminal belongs to a tracking area configured to the terminal and does not belong to the additional cell list, performing a cell-based area update procedure.

摘要： A method for resuming an RRC connection performed by a UE in a wireless communication system may include entering an EMM-IDLE mode with a suspend indication as the RRC connection is suspended; generating an initial NAS message when a procedure using the initial NAS message is triggered; requesting a resume of the RRC connection from an upper layer of the UE to a lower layer; and switching from the EMM-IDLE mode with the suspend indication to an EMM-CONNECTED mode when the upper layer receives an indication that the RRC connection is resumed from the lower layer.

摘要： 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.

摘要： Provided are a method and a device for processing a network slice-specific authentication and authorization (NSSAA) failure caused by a network error or timeout. An access and mobility management function (AMF): starts an NSSAA procedure for an NSSAA function (NSSAAF) and single network slice selection assistance information (S-NSSAI); and restarts the NSSAA procedure after waiting for a certain period, on the basis that the Hypertext Transfer protocol (HTTP) status code “504 Gateway Timeout” is received from the NSSAAF, and/or a response regarding the NSSAA procedure could not be received from the NSSAAF.

摘要： Provided are a method and device for efficient public land mobile network (PLMN) selection upon authentication failure for each network slice in a roaming network. A user equipment (UE) receives a registration rejection message from an access and mobility management function (AMF) of a first PLMN. The registration rejection message includes rejected network slice selection assistance information (NSSAI) including first single NSSAI (S-NSSAI) and cause value #62 for the rejected NSSAI. The UE: generates second requested NSSAI including second S-NSSAI on the basis that i) the UE does not have allowed NSSAI and configured NSSAI, and ii) default configured NSSAI includes the second S-NSSAI that is not included in the rejected NSSAI and corresponds to a network slice of which the UE requests registration; and transmits a second registration request message including the second requested NSSAI to the AMF of the first PLMN.

摘要： In one embodiment of the present invention, a method for enabling a UDM (Unified Data Management) to perform a registration related procedure of an AMF (Access and Mobility Management Function) in a wireless communication system comprises the steps of: receiving, by the UDM, a message related to serving AMF registration of a UE, which includes access type information and ID (Identity) information, from a first AMF; transmitting, by the UDM, a deregistration related message to a second AMF when the second AMF exists, wherein the second AMF is registered as a serving AMF of the UE and related to the access type information.
