摘要： 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.

摘要： According to one disclosure of the present specification, provided is a method in a network node that manages mobility in a second public land mobile network (PLMN). According to the method, an access request message from a terminal may be received through a base station in the second PLMN. In addition, a response message to an access request of the terminal may be transmitted. The response message may include information indicating rejection to the access request of the terminal, on the basis of the terminal that joined a third PLMN and on the basis of the base station that transmitted system information including information about a first PLMN on behalf of a base station of the first PLMN.

摘要： 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.

摘要： Provided are a method and device for efficient public land mobile network (PLMN) selection upon authentication failure for each network slice in a roaming network. A user equipment (UE) receives a registration rejection message from an access and mobility management function (AMF) of a first PLMN. The registration rejection message includes rejected network slice selection assistance information (NSSAI) including first single NSSAI (S-NSSAI) and cause value #62 for the rejected NSSAI. The UE: generates second requested NSSAI including second S-NSSAI on the basis that i) the UE does not have allowed NSSAI and configured NSSAI, and ii) default configured NSSAI includes the second S-NSSAI that is not included in the rejected NSSAI and corresponds to a network slice of which the UE requests registration; and transmits a second registration request message including the second requested NSSAI to the AMF of the first PLMN.

摘要： In a wireless communication system of the present disclosure, when activation of a protocol data unit (PDU) session of a user equipment (UE) is needed, the UE performs an access control check to determine whether an access attempt for the PDU session is allowed. If the access attempt is allowed, the UE transmits a service request for the PDU session. The access control check for the PDU session is performed even if the UE is in a connected state.

摘要： An embodiment of the present invention provides a method for supporting non-access stratum (NAS) signaling of a user equipment (UE) by a base station in a wireless communication system, the method comprising the steps of: transmitting, to the UE, information for supporting a connection to a next generation (NG) core; receiving a NAS-related message from the UE; performing one of MME selection and AMF selection according to whether the NAS-related message includes information regarding the use of NAS; and transmitting an NAS message to an MMF or an AMF which is determined as a result of performing one of the MME selection and the AMF selection.

摘要： A first network device receives a request associated with data notification for a user equipment (UE). When the UE is in a mode in which communication of mobile terminated data is restricted and the first network device detects that the UE is in a non-allowed area, the first network device rejects the request unless the data notification is for a regulatory prioritized service.

摘要： A core network to which a cell of a base station can be connected may not be specified to be one. For example, a cell may be connected to an EPC, may be connected to a next-generation core network, or may be connected to both an EPC and a next-generation core network. The base station may transmit core network information relating to a core network to which the cell is connected, on the cell. A user equipment may determine whether to camp on the cell on the basis of the core network information.
