  • 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”;
  • the base station 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.
  • the terminal 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.
  • the method for determining the number of system information requests and the monitoring of the network status determine that the system information is sent by the terminal for request or broadcast.
