Abstract
A random access method and a device are provided, to enable a device in the Internet of Things to implement random access. The method includes: selecting, by a terminal from at least two frequencies, frequencies used to send a physical random access channel PRACH signal, as frequencies occupied by target PRACH resources, where the at least two frequencies each have a preset bandwidth, and there is no intersection between frequency bands of the at least two frequencies; generating, by the terminal, a target PRACH signal based on the frequencies occupied by the target PRACH resources, a root allocated by a base station, and a cyclic shift corresponding to the root allocated by the base station; and sending, by the terminal, the target PRACH signal to the base station on the target PRACH resources.
