Abstract: A disclosure of the present specification provides a method for transmitting a paging message to a communication device by a first network node. The method may comprise the steps of: receiving a second message relating to downlink data to be transmitted to the communication device, from a second network node; in a case where the second message is related to a first service and the communication device is in an idle state for 3GPP access, transmitting a paging message and a NAS notification message to the communication device; and receiving a service request message relating to the downlink data from the communication device through the 3GPP access.

Abstract: A method for controlling a protocol data unit (PDU) session and a device therefor in a wireless communication system are disclosed. More specifically, a method for a session management function (SMF) to control a PDU session for low latency service in the wireless communication system includes receiving a request message related to the PDU session from a user equipment (UE), determining whether the request message related to the PDU session is a request for low latency service, and sending the UE a response message for the request message related to the PDU session based on the request message related to the PDU session including the request for low latency service, the response message including low latency information for a PDU session related to the request message related to the PDU session.

Abstract: A disclosure in the present specification provides a method for user equipment initiating a service request procedure. The method includes a step of the UE receiving a paging message. The UE may be registered to both of a 3rd generation partnership project (3GPP) access and a non-3GPP access within the same PLMN. The paging message may include access type information that is used so as to indicate the non-3GPP access. The method may include a step of initiating a UE triggered service request procedure. The UE triggered service request procedure may be initiated by transmitting a service request message including a list of permitted protocol data unit (PDU) sessions. The service request message may include an empty list of the permitted PDU sessions if there is no PDU sessions that can be reactivated in the 3GPP access.

Abstract: Provided is a tracking area assignment method by an access and mobility management function (AMF) in a wireless communication system. The method may include receiving, from a session management function (SMF), service and session continuity (SSC) mode indication information for a protocol data unit (PDU) session generated for a user equipment (UE), obtaining serving area information for a serving area of a serving user plane function (UPF) associated with the PDU session, determining the assignment of a new tracking area to the UE is necessary based on a tracking area pre-assigned to the UE and the serving area, and performing tracking area update for the assignment of the new tracking area to the UE if it is determined that the assignment of the new tracking area is necessary.

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 are a method for selecting a session and a service continuity mode in a wireless communication system and a device therefor. Specifically, a method for selecting a session-and-service continuity (SSC) mode associated with a protocol data unit (PDU) session by a user equipment (UE) in a wireless communication system supporting a plurality of SSC modes may comprise the steps of: receiving a data transmission request from an application; checking whether a first PDU session can support an SSC mode associated with the application; and when the first PDU session can support the SSC mode associated with the application, transmitting data of the application to a network by using the first PDU session without sending a request for establishment of a new second PDU session to the network, although an SSC mode of the first PDU session does not match the SSC mode associated with the application.
