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.

Abstract: This application relates to the wireless communications field, and discloses a random access method and apparatus, to resolve a problem of how a terminal device selects an uplink to perform random access. The method includes: selecting, by a terminal device, a first uplink from at least two preconfigured uplinks to perform random access; and selecting, by the terminal device when random access performed by using the first uplink fails, a second uplink from the at least two uplinks to perform random access, where the at least two uplinks are communications links between the terminal device and a first network device, the first network device and the terminal device are located in a same cell, the first uplink is a normal uplink NUL, and the second uplink is a supplementary uplink SUL. In this way, the terminal device selects an uplink to perform random access.

Abstract: Solutions for determining subframe configuration of a cell cluster are provided. In one example method, is obtained by a central control node, the radio resource information required by enhanced interference management and traffic adaptation eIMTA terminals and radio resource information required by conventional terminals in the cell cluster, where the cell cluster includes multiple cells. A TDD subframe configuration of the cell cluster is determined according to the radio resource information required by the eIMTA terminals and the radio resource information required by conventional terminals in the cell cluster. Each cell in the cell cluster is notified of the TDD subframe configuration information of the cell cluster, allowing the implementation of flexible TDD subframe configuration for terminals of different types in the cell cluster.
