Abstract: Disclosed in the present specification is a method by which a user equipment (UE) performs access control. The method can comprise the steps of: transmitting a protocol data unit (PDU) session establishment or modification request message; and receiving a PDU session establishment or modification rejection message. The rejection message can comprise information on a backoff timer and session network slice selection assistance information (S-NSSAI). The method can comprise the steps of: driving the backoff timer while being linked with the S-NSSAI; and performing access control on the basis of the S-NSSAI.

Abstract: One disclosure of the present specification provides a method by which a remote terminal selects any one from among relay terminals in a situation in which access control is applied because of network congestion. The method can comprise the steps of: receiving first information related to the access control from at least one of the relay terminals; comparing the first information with second information which is possessed by the remote terminal; selecting, from among the relay terminals, the relay terminal having transmitted the first information, when the first information completely coincides with the second information; and attempting a connection with the selected relay terminal.

Abstract: A user equipment can send an EPS mobility management (EMM) message including uplink data to a network node. The user equipment can determine that an EMM process complying with the EMM message has successfully been completed or can treat an EMM process complying with the EMM message as having been successfully completed if the user equipment receives an RRC disconnection, downlink data or service acceptance message for the EMM message.

Abstract: When a non-access stratum (NAS) message is generated in an NAS layer of a user equipment, the NAS layer transfers the NAS message and type information to an access stratum (AS) layer of the user equipment. An AS message containing the NAS message is transmitted to a network. The type information indicates whether the NAS message is a first type message containing user data or a second type message without user data.

Abstract: A method of controlling a backoff timer at a user equipment (UE) configured for dual priority, the method includes transmitting a non access stratum (NAS) request message without an access point name (APN) including a low priority indicator set to a first value to a network node, wherein the first NAS request message without the APN is an attach request message transmitted along with a packet data network (PDN) connectivity request without the APN; receiving a reject message for the NAS request message from the network node, and wherein a cause in the reject message is set to insufficient resources; setting the low priority indicator to a second value; and initiating a new attach procedure without the APN, while a session management (SM) backoff timer is running, wherein the first value of the low priority indicates that the UE is configured for NAS signaling low priority.

Abstract: One embodiment of the present invention relates to a method by which a packet data network gateway (PGW) processes data for an UE in a wireless communication system, the method comprising the steps of: receiving a tracking area identifier (TAI) list from a mobility management entity (MME); and receiving downlink data for the UE from a network, wherein the PGW buffers the downlink data when all of the tracking areas (TAs), which belong to the TAI list, are not included in the same serving gateway (SGW) service region.

Abstract: One disclosure of the present specification provides a method for using packet switching (PS) data off function in user equipment (UE). The method can comprise the steps of: determining whether a session management (SM) delay time timer or a mobility management (MM) delay time timer is being operated, in a state in which the transmission of a non-access stratum (NAS) request message for an SM is required according to a request for the activation or the inactivation of the PS data off function; and, according to the result of the determination, allowing an NAS layer of the UE to include activation or inactivation state information of the PS data off function in the NAS request message for an SM and transmit the same.

Abstract: A method and apparatus for performing application specific access control in a wireless communication system is provided. A user equipment (UE) receives access control related system information from a network, identifies initiation of a specific application, and determines whether or not access attempt for the specific application is allowed, based on the received access control related system information. Accordingly, the UE may determine whether or not to skip access control barring (ACB) check for the specific application, or whether or not to skip random access backoff for the specific application.

Abstract: It is disclosed a method and apparatus for controlling Idle-mode Signaling Reduction of a user equipment in a wireless communication system. Particularly, a method for controlling paging of a user equipment (UE) in which Idle-mode Signaling Reduction (ISR) is activated performed by a Serving Gateway (S-GW) in a wireless communication system may include transmitting a Downlink Data Notification (DDN) message to both of a first network node and a second network node, when receiving downlink data from a Packet Data Network Gateway (P-GW); and, when receiving a DDN Reject message from either one network node of the first network node and the second network node in response to the DDN message, transmitting a Stop Paging Indication message to a remaining network node.

Abstract: The present invention relates to a method and a device for performing group communication based on a proximity service (ProSe) in a wireless communication system. More specifically, the method comprises the steps of: enabling a relay terminal (relay user equipment, relay UE, ProSe UE-to-Network relay) to register group communication in a network node; and enabling the relay terminal to perform the group communication with the network node, wherein the group communication is configured to transmit a downlink signal using a multimedia broadcast and multimedia service (MBMS) if the number of terminals, except for a relayed terminal (relayed user equipment, relayed UE) among a plurality of terminals registered in the network node, is not less than a reference value.
