Abstract: A network slice selection method, a radio access device, and a terminal, where the method includes obtaining, by a radio access network (RAN) device, network slice information, sending, by the RAN device, a first message to a terminal, where the first message includes the network slice information, receiving, by the RAN device, a first access request message from the terminal after the terminal selects, based on the network slice information, first attribute information of a first network slice to be accessed by the terminal, and selecting, by the RAN device based on the first attribute information of the first network slice, a second network slice to be accessed by the terminal. The method enables an operator to flexibly configure a network slice, and reduces a communication latency and signaling overheads in a process in which a terminal selects a network slice.
