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: 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.

Abstract: 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.

Abstract: Provided in one disclosure of the present specification is a method selecting a network and routing traffic by a user equipment (UE). The method may comprise a step of receiving, from a base station, radio access network (RAN) support information, wherein the RAN support information may include RAN support parameters and a timer value. The method comprises the steps of: receiving, from an upper layer, an evaluation request; evaluating the RAN support parameters according to the request from the upper layer; delivering, to the upper layer, an indication which indicates a detour to wireless local area network (WLAN) access and a detour to 3GPP access according to the result of the evaluation, and/or an indication which indicates maintaining current access; and performing feedback to the step of evaluating when the timer expires.

Abstract: One disclosure of the present specification provides a method by which a network entity, which controls a control plane, determines whether to offload traffic of a user equipment (UE) to a wireless local area network (WLAN). The method can comprise a step of acquiring subscriber information on the UE from a subscriber information server, wherein the subscriber information can include a WLAN offloadability indication for a specific packet data network (PDN) connection. The method can comprise the steps of: determining WLAN offloadability for the specific PDN connection on the basis of the WLAN offloadability indication and configuration information; transmitting the WLAN offloadability indication to network nodes according to the determination; and transmitting the WLAN offloadability indication to the UE according to the determination.
