1. A method for enabling a terminal to accessing a base station, comprising:
broadcasting, by a first Base Station (BS) not supporting a shared carrier, a first priority list, wherein the first priority list comprises information indicating that a priority of a BS that does not support the shared carrier is higher than that of a BS that supports the shared carrier;
receiving, by the first BS, a first access request from a terminal, wherein the first access request indicates that the terminal selects to access the first BS according to the first priority list;
receiving, by the first BS, capability information from the terminal in a process of establishing a connection with the terminal, wherein the capability information comprises information about whether the terminal supports a frequency band of a sharing operator in the shared carrier; and
completing, by the first BS, the connection with the terminal to enable the terminal to access a non-shared network, in a case where the terminal does not support the frequency band of the sharing operator in the shared carrier.
