Abstract: A method includes: receiving an emergency call request; initiating, according to the emergency call request, n emergency calls by simultaneously using n call modes, where n is an integer not less than 2; and when a connection is established for one of the n emergency calls, releasing other emergency calls for which no connection has been established. By means of the embodiments of the present invention, multiple emergency calls may be simultaneously made, and when any one of the multiple emergency calls is connected, other emergency calls are released, reducing an emergency call time.

Abstract: A registration method applied in a terminal device includes sending a first request, where the first request is used to request to register in a first cell, receiving a first message, where the first message is used to indicate that the terminal device is successfully registered in the first cell, when the first message does not carry a first network slice identifier and the terminal device cannot establish a protocol data unit (PDU) session on a first network slice corresponding to the first network slice identifier, sending a second request, where the second request is used to request to register in a second cell, receiving a second message, where the second message carries a second network slice identifier, and establishing the PDU session on a second network slice corresponding to the second network slice identifier.

Abstract: A wireless communication method is applied to a communications system including a UE, a RAN, a first core network entity, and at least one network slice. The wireless communication method includes: establishing, by the first core network entity, a signaling connection to the UE; receiving, by the first core network entity and from the UE via the signaling connection, network slice information and a non-access stratum NAS message; determining, by the first core network entity and based on the network slice information, a target network slice from the at least one network slice, where the target network slice includes a second core network entity, and the UE performs NAS communication with the second core network entity using the RAN and the first core network entity; and sending, by the first core network entity, the NAS message to the second core network entity.

Abstract: Embodiments provide a core network selection method, an apparatus, and a system. The method includes the following steps: obtaining first dedicated core network (DCN) information from an access network device, where the first DCN information includes information about at least one DCN that can be accessed by the access network device. The method also includes selecting a to-be-accessed DCN from the at least one DCN according to the first DCN information, and sending information about the to-be-accessed DCN to the access network device, so that the access network device determines a core network device according to the information about the to-be-accessed DCN.
