    Abstract: 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 control base station (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 data base station (DBS) identification (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.
