Abstract: A method for discarding at least one packet by a user equipment (UE) in a wireless communication system is disclosed. The method includes steps of storing the at least one packet received from an upper layer in a buffer; determining whether or not a number of packets in the buffer is equal to or greater than a threshold value; and discarding the at least one packet from the buffer when the number of packets in the buffer is equal to or greater than the threshold value.

Abstract: Disclosed herein are a method for tracking area update in a wireless communication system and an apparatus therefor. Specifically, a method for user equipment (UE) to perform a tracking area update (TAU) procedure in a wireless communication system comprises: a step of transmitting a TAU request message to a mobility management entity (MME); and a step of receiving a TAU accept message from the MME, wherein if the UE uses signaling optimization to enable the delivery of user data through a control plane over the MME, and the UE does not have pending user data to be transmitted through a user plane and has pending user data to be transmitted through the control plane over the MME, then a first active flag can be set in the TAU request message.

Abstract: One disclosure of the present specification provides a method for a proxy-call session control function (P-CSCF) of a home public land mobile network (H-PLMN) to register a roaming user equipment with an IP multimedia subsystem (IMS) network. The method may comprise the steps of: receiving an identifier of a visited public land mobile network (V-PLMN) in which a user equipment is roaming, wherein the identifier of the V-PLMN is received in a state where packet data network (PDN) connection for the user equipment is established but the user equipment is not registered with the IMS network; receiving, from the user equipment, a REGISTER message for registration with the IMS network; adding the identifier of the V-PLMN to a header of the REGISTER message; and transmitting the REGISTER message to which the identifier of the V-PLMN is added to an Interrogating-CSCF (I-CSCF).

Abstract: An aspect of the present invention relates to a UE-initiated de-registration method by an AMF in a wireless communication system, and comprises the steps of: receiving, from UE, a de-registration request message that requests de-registration, wherein the de-registration request message includes de-registration type information and first access type information indicating a target access to which the de-registration is to be applied; requesting, when the UE has an established protocol data unit (PDU) session through the target access, an SMF to release the established PDU session; and transmitting a de-registration accept message to the UE depending on the de-registration type

Abstract: One disclosure of the present specification provides a method for a proxy-call session control function (P-CSCF) to obtain an identifier of a visited public land mobile network (V-PLMN) in order to register a user equipment (UE) roaming in the V-PLMN into an IP multimedia subsystem (IMS) network. The method may comprise the steps of: receiving a response message from an Interrogating-CSCF (I-CSCF) in response to the transmission of a REGISTER message for registering a user equipment into an IMS network; determining whether the received response message is a 401 unauthorized message; when the received response message is a 401 unauthorized message, transmitting the response message to the user equipment and generating an interface for transmitting and receiving data to and from an entity of an EPC network; and receiving an identifier of the V-PLMN from the entity of the EPC network.
