Abstract: A user equipment (UE) may receive or transmit a protocol data unit (PDU). The PDU includes a service data unit (SDU) type field. The SDU type field may be set to a value indicating a vehicle-to-everything (V2X) type. When the SDU type field is set to a value indicating a V2X type, the PDU may include an additional field indicating an application or protocol type for data of an SDU in the PDU.

Abstract: One disclosure of the present specification provides a method for a terminal creating a session, the terminal supporting next-generation mobile communication. The method may comprise the steps of: determining that a session must be newly created if the creation of a session is not included in a process of attaching to a core network of a next-generation mobile communication; on the basis of service type information, determining that the session being newly created needs to be always-on, or in other words, always-connected; and transmitting, to a control plane (CP) function node for managing the session, a connectivity request message including information indicating that the session that needs to be always-on, or in other words, always-connected, has been requested.

Abstract: Disclosed herein are a method and apparatus for monitoring UE reachability in a wireless communication system. A method for monitoring UE reachability may include receiving, by a Mobility Management Entity, a monitoring request message for UE reachability including a maximum response time from a Home Subscriber Server, detecting, by the MME, the UE reachability if it is expected that paging is able to be transmitted to UE when extended Discontinuous Reception is applied to the UE, and sending, by the MME, a UE reachability notification to a Service Capability Exposure Function before a next paging occasion of the UE, wherein the maximum response time may indicate a time during which the UE maintains a reachable state so that downlink data is reliably delivered to the UE, and wherein an occasion when the UE reachability notification is transmitted may be determined by taking into consideration the maximum response time.

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 for controlling mobile terminated (MT) data in a wireless communication system and a device therefor are disclosed. The method for controlling MT data by a user equipment (UE) in a wireless communication system includes receiving paging from a network and transmitting a tracking area update (TAU) request message to a mobility management entity (MME) in response to the paging when an EPS update status of the UE is EU2 NOT UPDATED due to an unsuccessful attempt of a last TAU procedure of the UE upon receiving the paging, wherein when the UE is using only signaling optimization to enable delivery of user data over a control plane via the MME, a first active flag in the TAU request message is set.
