Abstract: A method of transmitting and receiving an emergency PDN connection-related signal, which is transmitted and received by an MME in a wireless communication system, comprising the steps of: receiving a PDN connectivity request message from a UE; determining whether or not an IMS NNI exists between a HPLMN (home public land mobile network) of the UE and a PLMN of the MME and whether or not an anonymous emergency call is permitted; and if the IMS NNI does not exist and the anonymous emergency call is not permitted, transmitting a PDN connectivity reject message to the UE.

Abstract translation: 一种在无线通信系统中发送和接收由MME发送和接收的紧急PDN连接相关信号的方法，包括以下步骤：从UE接收PDN连接请求消息; 确定在所述UE的HPLMN（归属公共陆地移动网络）和所述MME的PLMN之间是否存在IMS NNI以及是否允许匿名紧急呼叫; 并且如果IMS NNI不存在并且不允许匿名紧急呼叫，则向UE发送PDN连接拒绝消息。

Abstract: One disclosure of the present specification provides a method by which a network control node performs communication. The method comprises the steps of: determining whether to request, from a network function (NF), control for a network slice on the basis of a session, which is managed by a network control node, being related to an interworking procedure and on the basis of the network slice being controlled by a provider policy set in the network control node, the network slice being related to the session; transmitting a control request message for the network slice to the NF, on the basis of the determination that the network control node requests control for the network slice; and receiving a response message from the NF, wherein the response message includes information about whether the session is available in the network slice.

Abstract: One embodiment of the present specification can provide a method for performing a protocol data unit (PDU) session-related procedure. The method can comprise the steps of: transmitting, to a session management function (SMF) device, a PDU session-related message including a first indication related to communication through a PC5 link; and receiving a response message from the SMF device. The response message can include: a first quality of service (QoS) rule to be used on a Uu link; a second QoS rule to be used on a PC5 link; and a path selection rule about whether data should be transmitted through the Uu link or the PC5 link.

Abstract: One disclosure of the present specification provides a communication method, for handling a network error, performed by a terminal. The terminal can receive information relating to a second public land mobile network (PLMN) to which the terminal is subscribed from a base station in a first PLMN. The terminal can be connected to the first PLMN by means of the base station in the first PLMN on the basis of the information relating to the second PLMN. Information notifying of an error which has occurred in the second PLMN can be displayed on a display of the terminal.

Abstract: A disclosure according to the present specification provides a method of having an access by a terminal subscribing to a first public land mobile network (PLMN). The method may comprise a step of transmitting a first request message to a network node via 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. The method may comprise a step of receiving, from the network node, a first response message that is a response to the first request message. The first response message may include information indicating that there is a service failure in the first PLMN. The method may comprise a step of transmitting a second request message to the second PLMN or reselecting another PLMN instead of the first PLMN, which has a service failure, on the basis of the first response message including the information.
