Abstract: Embodiments of the present application relates to a method and device for random access, for use in resolving the problem that no current random access process can satisfy requirements of a satellite communication system. The method of the embodiments of the present application comprises: receiving and obtaining a related parameter in a configuration message, the related parameter comprising common cell delay information; generating a physical random access channel random access preamble (PRACH Preamble) sequence, and determining an uplink sending timing location according to the common cell delay information; and sending the PRACH Preamble sequence on a time-frequency resource corresponding to the uplink sending timing location. A relative transmission delay and a multi-path channel delay from a terminal, to a satellite, and to a base station are compensated according to the determined uplink sending timing location, thereby reducing overheads of a PRACH channel.
