1. A system information transmission method, performed by a terminal side, comprising:
sending request information to a network device in the case that target Other System Information (Other SI) is to be requested, wherein the target Other SI is at least one of Other SI requested by a random access message one or Other SI requested by a random access message three, the Other SI is system information other than minimum system information;
receiving a random access message two or a random access message four which is sent by the network device based on the request information and carries preset indication information; and
determining whether to receive subsequent broadcast information based on the random access message two or the random access message four;
wherein the indication information is ACK information, and the ACK information is configured to indicate that the subsequent broadcast information comprises all or a part of system information of the target Other SI;
wherein the determining whether to receive the subsequent broadcast information based on the random access message two or the random access message four comprises:
receiving the subsequent broadcast information through a preset transmission resource, in the case that the random access message two or the random access message four carries the ACK information; or ignoring the subsequent broadcast information, in the case that the random access message two or the random access message four does not carry the ACK information; or
detecting the identity information for indicating the Other SI in the minimum system information, in the case that the random access message two or the random access message four does not carry the ACK information, wherein the identity information of the Other SI is configured to indicate the identity information of the Other SI broadcasted by the subsequent broadcast information;
receiving the subsequent broadcast information through a preset transmission resource, in the case that the identity information of the Other SI comprises the identity information of all or a part of system information of the target Other SI;
and/or,
the ACK information comprises at least one of: Other SI identity information, system information block identity information corresponding to the Other SI, system information block group identity information corresponding to the Other SI and system information block function identity information corresponding to the Other SI;
the indication information is non-acknowledgement (NACK) information, and the NACK information is configured to indicate that the subsequent broadcast information does not include any system information in the target Other SI within a preset time period.
