Document Type and Number:
Japanese Patent JP6700434
Kind Code:
B2
Abstract:
The present invention provides a wireless communication method and a device. The method is applied to a communications system. The communications system includes user equipment UE, a radio access network RAN, a first core network entity, and at least one network slice. The method includes: establishing, by the first core network entity, a signaling connection to the UE; receiving, by the first core network entity, network slice information and a non-access stratum NAS message that are sent by the UE over the signaling connection; determining, by the first core network entity, a target network slice from the at least one network slice based on the network slice information, where the target network slice includes a second core network entity, and the UE performs NAS communication with the second core network entity by 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. In this way, an amount of signaling in a communication process can be reduced, and network management and maintenance efficiency can be improved.
