The present invention will be described in detail below in conjunction with specific application scenario embodiments.

This embodiment provides a system information transmission method, as shown in FIG. 11, the specific steps are as follows:

Step 1101: The base station responds to the system information requested by the terminal in a terminal request manner.

Here, it is assumed that the current base station sends the system information in the manner requested by the terminal, and the terminal must initiate the system information request to obtain the corresponding system information. The terminal sends a system information request for indicating a certain system information that the base station wishes to obtain. The system information request may carry a system information type, such as SIB1.

In application, the system information request may be notified to the base station by using an RRC connection setup request message, or may be notified to the base station by using a MAC CE, and may also notify the base station by using a preamble code or Msg3 in the RACH procedure.

Step 1102: The base station receives the system information request sent by the terminal, and performs statistics on the number of requests.

Here, the number of requests counted by the base station may be the number of users (terminals) that initiate the system information request, or may be the number of system information requests.

There are two ways for the base station to receive system information requests:

Manner 1: The base station receives the system information request in a fixed time range T.

The fixed time range T can be one or more radio frames. The specific time range depends on the base station implementation. For example, when the fixed time range T is a single radio frame, the base station counts the number of requests in each radio frame range, that is, the base station obtains a corresponding request density in each radio frame.

Manner 2: The base station receives the system information request in the form of a sliding window.

The sliding granularity may be one subframe, or a time unit configured by other base stations.

The sliding window length can be fixed or not fixed:

For the case where the window length is fixed, the base station counts the number of requests in the window for a long time, that is, the request density;

For the case where the window length is not fixed, the base station counts the total number of requests received from the base station in response to the system information mode requested by the terminal in the form of the terminal request form, that is, the requested cumulative number.

Step 1103: The base station determines whether the received system information request quantity exceeds (greater than or equal to) the preset threshold Th. If the preset threshold Th is greater than or equal to the preset threshold Th, step 1104 is performed; otherwise, return to step 1101 to continue the current terminal request mode to respond to the terminal request. system message;

Step 1104: The base station determines to transmit the system information by means of broadcast, and sends a “system information transmission mode change indication”;

Here, the base station may send the “system information transmission mode change indication” in the manner of broadcast, paging, RRC dedicated signaling, or physical layer control channel indication; after receiving the indication, the terminal will not initiate the system information request, and Is receiving system information broadcast by the base station;

The "system information transmission mode change instruction" may be 1 bit. When the indication is 1, it indicates that the base station transmits system information in a broadcast manner; when the indication is 0, it indicates that the base station responds to the system information requested by the terminal in a terminal request manner.

Step 1105: The base station sends the system information in a broadcast manner.

Step 1106: The base station determines whether the current network status is suitable for adopting the system information of the terminal request mode, and if yes, executing step 1107; otherwise, returning to step 1105, continuing to send the system information in a broadcast manner;

Here, the network status corresponding to the terminal request mode may include, but is not limited to:

1) The number of terminals connected by the base station is less than a threshold;

2) During the period when the base station traffic is low or the number of connected terminals is low, the base station actively switches to the terminal request response mode during the period; for example, based on the big data statistics result, the terminal is needed from 24 pm to 6 am Request system information.

3) The core network instructs the base station to change the system message transmission mode from broadcast to terminal request response.

Step 1107: The base station converts the system information transmission mode from the broadcast to the terminal request response, and delivers the “system information transmission mode change indication”;

After transmitting the "system information transmission mode change instruction", the base station will not transmit the system information by broadcast, but will only respond to the terminal requesting the system information request, and return to step 1101.

After receiving the indication, the terminal no longer receives the broadcasted system information, but initiates a request to the base station when some/some system information is needed.
