Abstract: Provided are a random access method and apparatus. The method can include: a first cluster head in a first cluster formed by multiple UEs selects a preamble from a preset preamble set, and transmits the preamble to a base station, each preamble in the preamble set indicating the number of UEs corresponding to the each preamble, and the number of UEs corresponding to the selected preamble being equal to the number of cluster members in the first cluster; the first cluster head receives a response message transmitted by the base station in response to the preamble; and the first cluster head broadcasts, to each cluster member in the first cluster, the resource information for establishing the RRC connection and the C-RNTI.
