Abstract:
The present invention relates to a wireless communication system, and more particularly, to a method and an apparatus for processing a NAS signaling request. A method for performing a non-access stratum (NAS) signaling process by means of a terminal in a wireless communication system according to one embodiment of the present invention comprises: a step of receiving a first message that includes information indicating a network failure from a network node of a first network; a step of starting a timer relating to a network selection; and a step of selecting a second network from among network candidates excluding the first network during the operation of the timer relating to a network selection.
Abstract:
A wireless communication system is disclosed. More particularly, a control method and device based on multiple priorities in a wireless communication system is disclosed. The method of establishing a packet data network (PDN) connection in a terminal configured with multiple priorities includes establishing a first PDN connection set to a first priority level, determining whether the first PDN connection set to the first priority level is present and a second PDN connection set to a second priority level is requested to be established, and transmitting a PDN connection request message for the second PDN connection set to the second priority level if the first PDN set to the first priority level is present and the second PDN connection set to the second priority level is requested to be established.
Abstract:
Proposed is a method for effectively supporting quality of service (QOS) of artificial intelligence (AI) and machine learning (ML) services. An application function (AF) transmits information about an uplink (UL)/downlink (DL) notification request to a session management function (SMF). The SMF generates a QoS profile on the basis of a policy and charging control (PCC) rule including information about the UL/DL notification request, and transmits the QoS profile to a next generation (NG)-radio access network (RAN). The NG-RAN transmits, to the SMF, a notification message including response information with respect to the UL/DL notification request, on the basis of the occurrence of an event related to the UL/DL notification request.
Abstract:
A method and apparatus for service data adaptation protocol (SDAP) configuration for a destination in sidelink communication is provided. A wireless device establishes a service data adaptation protocol (SDAP) entity based on a SDAP configuration per destination of a sidelink communication. This can be achieved by the wireless device receiving a configuration of one or more sidelink radio bearers (SLRBs), which includes an SDAP configuration for each of the one or more SLRBs. Each SDAP configuration, in turn, includes a list of Quality of Service Flow Identities (QFIs) for a corresponding destination, from among one or more destinations, to be mapped to a corresponding SLRB. One or more transmitting SDAP entities can then be established for each of the one or more destinations.
Abstract:
The present disclosure relates to an operating method of an SMF in a wireless communication system, comprising the steps of: determining, by the SMF, whether a UE receiving an MBS within an MBS region leaves the MBS region; when the UE has left the MBS region, starting a timer regarding UE leaving; and providing the MBS on the basis of the timer regarding the UE leaving, wherein, if the UE returns to the MBS region before the timer regarding the UE leaving expires, then the MBS for the UE is resumed, and if the UE is located outside the MBS region until the timer regarding the UE leaving expires, then a UE leaving operation for the MBS may be performed.
Abstract:
One disclosure of the present specification provides a method for establishing communication by a session management function (SMF). The method comprises the steps of: transmitting to a base station a request message requesting resource allocation between a first protocol data unit (PDU) session and a second PDU session, wherein the first PDU session and the second PDU session are established by user equipment (UE) on the basis of the same PDU session pair ID; receiving a response message from the base station, wherein the response message comprises indication information indicating whether or not a disjoint UP path is allocated to the first PDU session and the second PDU session, respectively; and transmitting the indication information to the UE.
Abstract:
A disclosure of the present specification provides a method by which a UE performs measurement-related communication. The method may comprise the steps of: performing access measure-ment for a first QoS flow; determining that the access measurement for the first QoS flow is applied to a second QoS flow; and determining not to perform access measurement for the second QoS flow.
Abstract:
A disclosure of the present specification provides a method for performing, by a first RAN node, communication related to a network slice. The method may comprise the steps of: receiving, from an AMF, a PDU session resource establishment request message including information regarding a second PDU session; on the basis of the first RAN node not supporting a second network slice, determining to move UE to a second RAN node that supports the second network slice; and on the basis of being determined to move the UE to the second node, transmitting a PDU session resource establishment response message to the AMF.
Abstract:
Provided in one embodiment of the present specification is a method by which a UE performs communication related to traffic control. The method may comprise steps in which: the UE transmits, to an SMF node, capability information related to supporting validity criteria for ATSSS rules; the UE receives one or more ATSSS rules from the SMF node; and the UE applies the one or more ATSSS rules.
Abstract:
One disclosure of the present specification provides a method by which a next-generation radio access network (NG-RAN) performs communication. Comprised are the steps of: receiving a message from an access and mobility management function (AMF), wherein the message comprises i) a registration accept message, ii) allowed network slice selection assistance information (NSSAI) including a first network slice already allowed for a user equipment (UE), and iii) target NSSAI including a second; and on the basis of the join request included in the first message being the first join request for the multicast group from among the relay UE and the one or more remote UEs receiving a network connection service from the relay UE, transmitting a second message to a base station.
