In an exemplary embodiment, the foregoing method for updating broadcast system information may be, but is not limited to, applied to a cell or a node capable of performing a communication connection, for example, a macro base station, a micro base station, a pico base station, a distributed base station, a macro cell, a small cell, TRP and TP, etc.

After obtaining the changed broadcast system information of the cell or the node, the system information table (SIT) is updated based on the changed broadcast system information, and then the change indication message is sent to the cell or the node, so that the cell or the node can be timely The user equipment broadcasts the message that the SIT is changed, and solves the problem that the user equipment cannot obtain the updated SIT in time in the related art, thereby improving the success rate of the user equipment acquiring the updated SIT.

In the above embodiment of the present application, the broadcast system information of multiple cells or multiple nodes may be acquired by a certain cell or node (for example, cell 1). Then, the cell 1 can assemble the acquired broadcast system information to form an SIT and broadcast it. It should be noted that, in the embodiment of the present invention, the broadcast system information of the cell or the node may be assembled into a SIT by using a functional entity (Functionality) other than the cell or the node, where the functional entity may be combined with multiple cells or Each of the plurality of nodes performs information interaction with each of the nodes.

In the following embodiments of the present application, a cell is taken as an example for description.

For example, the cell 1 acquires broadcast system information (SITn) of a cell or a node (for example, cell 2 and cell 3), wherein the broadcast system information SIT2 of the cell 2 and the broadcast system information SIT3 of the cell 3 may be generated by the same base station, or Different base stations.

If the broadcast system information SIT1, SIT2, and SIT3 of the cell 1, cell 2, and cell 3 are generated by different base stations, that is, there is an external communication interface between the cell 1 and the cell 2 and the cell 3, the cell 2 and the cell 3 may pass through the external The communication message of the communication interface transmits SIT2 and SIT3 to the base station 1 corresponding to the cell 1. If the broadcast system information SIT1, SIT2, and SIT3 of Cell 1, Cell 2, and Cell 3 are generated by the same base station, Cell 2 and Cell 3 can transmit SIT2 and SIT3 to Cell 1 through the internal communication message of the base station.

In the embodiment of the present invention, the broadcast system information of the node (or the cell) is obtained by a node (or a cell) to broadcast, thereby avoiding waste of resources caused by continuous broadcast of the node or the cell.
