If the second timer is not overtime, waiting for the second timer to be overtime, and if the target system information sent by the network side equipment is received before the second timer is overtime, stopping the second timer from timing and resetting, and stopping sending the request; and if the second timer is overtime, the request is retransmitted. Since the second timer is set to extend the time for retransmitting the request in the present embodiment, the number of times of retransmitting the request can be reduced in the same period of time, and thus the power consumption of the user terminal is reduced.
Optionally, referring to fig. 3, before the step of retransmitting the request, the method further includes:
step 106, starting a third timer to start timing when the request is sent;
step 107, if the target system information is received before the third timer times out, stopping the third timer from timing and resetting, and stopping sending the request;

receiving broadcast messages sent by network side equipment;
if the broadcast message carries target indication information, stopping sending the request, wherein the target indication information is used for indicating the target system information to be sent through broadcast;
and if the broadcast message does not carry the target indication information, executing the step of resending the request.
In this embodiment, after sending the request for obtaining the target system information, if the target system information sent by the network side device is not received, the user terminal needs to resend the request, before resending the request, broadcast information sent by the network side device may be received, and it is determined whether the broadcast message carries target indication information, where the target indication information is used to indicate that the target system information is sent by broadcast, and of course, may also indicate that the target system information is sent by broadcast, and receive the target system information according to the scheduling information, and if the broadcast message carries the target indication information, the target system information may be received from broadcast information.
For example, before sending the request, the network side device does not send the target system information as an broadcast message, and after sending the request, the network side device sends the target system information as a broadcast message and sends the target indication message in broadcast message, at which point the sending of the request may be stopped.
Step , in order to ensure timeliness of obtaining the target system information, when the broadcast message carries the target indication information, it may be determined whether the target system information is received within time, if the target system information is received, the request is stopped from being sent, and if the target system information is not received, the request is sent again.
If the broadcast message carries the target indication information, receiving the target system information in a preset time period;
if the target system information is received within the preset time period, stopping sending the request;
and if the target system information is not received within the preset time period, executing the step of retransmitting the request.
In this embodiment, if the broadcast message carries the target indication information, a fifth timer may be started, and before the fifth timer expires, the target system information is received from the broadcast message.
