Abstract: This application provides an interference measurement method and an apparatus. The interference measurement method includes: A network device sends first indication information to a terminal device. The first indication information indicates the terminal device to measure signal quality of a first signal. The network device sends the first signal to the terminal device by using N analog beams. N is an integer greater than or equal to 1, and the analog beam meets a first preset condition. The network device receives a measurement result from the terminal device. The measurement result is the signal quality of the first signal. According to the interference measurement method and the apparatus provided in this application, measurement overheads can be reduced.

Abstract: Embodiments of the present invention provide a method for controlling UE to access a communications network of a high-speed moving vehicle, a core network control plane node device, a base station, UE, and a communications system. The method includes: determining that UE accessing the communications network is first-type UE, allocating a temporary identifier that includes a first sequence to the UE, and sending the temporary identifier to the UE, where when the UE accesses a public network, the first sequence is used to instruct the base station to transfer the UE to the communications network. In the embodiments of the present invention, user experience of the UE is improved.
