Abstract

The embodiment of the present application discloses a communication method, a terminal device, and a core network device, wherein the method includes: the terminal device sends a registration request message including first network slice information to the core network device via the radio access network device, and the first network slice The information is the information of the first network slice corresponding to the PDU session that the terminal device expects to establish; the terminal device receives the information including the first registration area allocated for the terminal device and the second network slice information sent by the core network device via the wireless access network device In the registration receiving message, the second network slice information is the information of the second network slice allowed to be used by the terminal device in the first registration area; wherein, the second network slice information includes the first network slice information. By adopting the present application, it is possible to better meet the communication requirements of terminal devices by using network slicing.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a wireless communication method, terminal equipment, and core network equipment. Background technique [0002] The fifth generation (5th Generation, 5G) communication system introduces the concept of network slicing, and the network slicing technology can divide a physical network into multiple virtual networks. A virtual network is regarded as a "network slice", and each network slice is independent of each other. Different sessions in an end device may require network slices corresponding to each session to provide services. In practical applications, the terminal device needs to send the requested network slicing information to the core network device, and the core network device will feed back the allowed network slicing information to the terminal device. If the network slicing information requested by the terminal device is not in the allowed networ...
