The present disclosure provides a method for broadcasting system information. The method includes: obtaining preset global system information, the global system information including pre-divided basic system information and terminal-related system information; broadcasting the basic system information on a broadcast channel; receiving a message uploaded by User Equipment (UE) through an uplink channel, and extracting a system information requirement message included in the message; determining target system information in the terminal-related system information according to an indication of the system information requirement message. By adopting the present disclosure, there is no need to send all system information to a terminal at one time, thereby occupying less capacity resources of a base station broadcast channel and improving resource utilization of the broadcast channel.
