摘要： The present invention relates to the field of communications technologies, and discloses a method for accessing a base station by a terminal, and an apparatus. In this provided solution, after a CBS receives an access request message sent by the terminal, the CBS determines, according to received identification information of the terminal and a correspondence between the DBS ID and the identification information of the terminal, a DBS ID that accesses the terminal; then a DBS corresponding to the DBS ID allocates access resource information to the terminal; finally, the terminal accesses the DBS. Therefore, the terminal can also access the DBS even if there is no cell ID in a cell covered by the DBS, thereby avoiding a problem that the terminal cannot access the base station when accessing the base station in a data and signaling separation network, and a problem of a relatively complex access process and a waste of processing resources in the terminal is resolved because there is no process of calculating multiple cell IDs.
