Provided are a method and a device for processing network slice selection assistance information (NSSAI) rejected due to a network slice-specific authentication and authorization (NSSAA) failure. A user equipment (UE) receives a UE configuration update command message from an access and mobility management function (AMF). On the basis of failure of NSSAA with respect to single NSSAI (S-NSSAI0, the UE configuration update command message includes time information related to a timer. The UE adds the S-NSSAI to a rejected NSSAI, starts the timer on the basis of the time information, and deletes the S-NSSAI included in the rejected NSSAI after the timer expires.

Processing of NSSAI rejected due to NSSAA failure

One disclosure of the present specification provides a method for a UE to perform communication. The method includes transmitting a NAS request message to a first AMF; receiving a NAS response message from the first AMF; transmitting a registration request message to a second AMF; and receiving a registration acceptance message including LADN information from the second AMF.

Provided are a method and device for obtaining, managing, and verifying user consent for external provision of user analytics. Unified data management (UDM) receives, from a network data analytics function (NWDAF), a first request message for whether consent of a specific user has been received with respect to data request collection for the specific user, which is requested by an application function (AF), and transmitting a first response message including a parameter indicating the presence or absence of user consent to the NWDAF. In this case, the parameter indicates that there is no consent of the specific user. The UDM also receives, from the AF, a second request message including an ID of the specific user, consent acquired from the specific user, and HASH, and updating the parameter indicating the presence or absence of user consent, based on the consent acquired from the specific user.

Method and device for obtaining, managing, and verifying user consent for external provision of user data analysis information

Provided are a method for managing a prohibited PLMN list during disaster roaming, and an apparatus supporting same. User Equipment (UE) determines, when there is no available public land mobile network (PLMN) other than PLMNs included in a first list, whether the PLMNs included in the first list can provide a disaster roaming service, and includes in a second list at least one PLMN that can provide the disaster roaming service, from among the PLMNs included in the first list. On the basis that a disaster condition is applied to a home PLMN (HPLMN), the UE i) performs PLMN selection for the at least one PLMN included in the second list, and ii) selects a disaster roaming PLMN from among the at least one PLMN and receives the disaster roaming service provided from the disaster roaming PLMN.

Method for managing prohibited PLMN list during disaster roaming, and apparatus supporting same

A method and apparatus for utilizing analytics on power consumption information. A Network Function (NF) supporting a Service Function Chaining (SFC) receives an N4 rule generated by a Session Management Function (SMF) from the SMF. The N4 rule includes information related to change of an SFC path based on power consumption of a UE. The NF supporting the SFC determines an SFC path based on the information related to the change of the SFC path, and communicates with the UE based on the determined SFC path.

Method for utilizing analytics on power consumption information

One disclosure of the present specification provides a method in which a UE performs communication related to PS Data Off. The method may comprise: a step for transmitting a first PDU session establishment request message in order to establish a PDU session associated with non-3GPP access or 3GPP access; and a step for transmitting a second PDU session establishment request message in order to perform a handover between the non-3GPP access and the 3GPP access for the PDU.

Communication related to PS data off

A disclosure of the present specification provides a method for performing, by a visited public land mobile network-policy control function (V-PCF), communication using edge computing. The method comprises the steps of: establishing UE policy association with a home public land mobile network-policy control function (H-PCF); receiving a first subscription message from the H-PCF; and transmitting a second subscription message to a visited public land mobile network-unified data repository (V-UDR). The first subscription message is a message that requests a notification, according to edge application server (EAS) information being updated or modified, the second subscription message is a message that requests a notification, according to the EAS information being updated or modified, the second subscription message is based on the first subscription message, and the EAS information may be information that is generated by an application function (AF) and transmitted to the V-UDR.

Communication associated with edge computing

One disclosure of the present specification provides a communication method related to a change of an application server performed by an SMF node. The method may comprise: a step for transmitting a notification message related to a change of a user plane path to an AF node; a step for receiving a response message from the AF node in response to the notification message; and a step for transmitting a message including information on an IP address of the changed application server to a terminal through an AMF node.

Communication related to change of application server

A disclosure of the present specification provides a method of performing communication related to a network slice by a network node. The method may comprise the steps of: receiving a registration request message from a UE; determining, on the basis of information on a network slice, whether the UE is allowed to access the network slice; and when it is determined that the UE is not allowed to access the network slice due to a network slice limit control, transmitting, to the UE, a registration acceptance message including information on a waiting network slice.

Communication related to network slice

One disclosure of the present specification provides a method by which UE performs communication related to a network slice. The method may comprise steps in which: a registration request message including information about a network slice which the UE wants to access is transmitted to a network node; a registration acceptance message including information about a standby network slice is received; and information notifying that the standby network slice has been accessed is displayed on the display of the UE on the basis of the information about the standby network slice.

A disclosure of the present specification provides a method for performing relay communication by a first UE. The method may comprise the steps of: transmitting a request message including UE ID, relay information, UE type information, and UE public key information to an application server through a 5G core network; receiving, from the application server, a security-related message in response to the request message; establishing a security link with the relay UE on the basis of first credential information; and receiving an IP message for configuring a security channel in an IP layer from a second UE.

Relay communication

A method performed by a terminal operating in a wireless communication system. Based on that the terminal is located in a non-allowed area, and based on the terminal having a pending uplink signaling to inform a change in a Packet Switch (PS) data off status of the terminal, the terminal transmits a service request message to a network node. The service request message includes service type information that is related to the change in the PS data off status of the terminal. The terminal then receives, from the network node, a response message to the service request message.

Method for performing communication related to packet switch (PS) data off

One disclosure of the present specification provides a method by which a terminal that joined a first public land mobile network (PLMN) performs a connection. The method may comprise a step for transmitting a first request message to a network node through a base station. The base station may be a base station of a second PLMN that broadcasts system information including information about the first PLMN.
