1. a method for Stochastic accessing, is characterized in that, comprises the following steps:

  • User equipment (UE) receives the Stochastic accessing configuration information that base station sends, and determines exclusive random access guiding preamble sequence that the community that needs to carry out Stochastic accessing uses and the dedicated physical Random Access Channel PRACH resource for sending described exclusive preamble sequence according to described configuration information;

    Described UE sends described exclusive preamble sequence by the described exclusive PRACH resource determined to base station on the community needing to carry out Stochastic accessing;

    Described UE is corresponding in the described community that have sent exclusive preamble sequence, in the dedicated search space of the described UE on the community of transmitting the dispatch of described community, detect the PDCCH of described RA-RNTI scrambling, have sent the accidental access response of the community of exclusive preamble sequence described in obtaining from described PDCCH, described accidental access response at least comprises for the described timing advance TA that have sent the uplink synchronous adjustment of the community of exclusive preamble sequence.
