Description

Information acquisition method, information indication method, information acquisition device and communication equipment Technical Field The application belongs to the technical field of communication, and particularly relates to an information acquisition method, an information indication device and communication equipment. Background The main purpose of the system information block 1 (System Information Blocks, SIB 1) is to provide critical information, including random access parameters, needed by the terminal to access the cell. In addition, SIB1 includes scheduling information for other system information (Other System Information, OSI), which helps the terminal to efficiently acquire and manage system information. For example, the broadcast status of OSI may be indicated in SIB1, such that the terminal may acquire OSI based on the broadcast status of OSI indicated in SIB 1. If the broadcasting state of OSI in SIB1 is set to broadcast, the state should be maintained for one system information modification period, i.e. change to non-broadcast only in the next system information modification period, but if the broadcasting state of OSI in this period is set to non-broadcast, the state may be changed to broadcast in the current system information modification period. In the related art, the terminal is not notified of a short message (short message) by a change in the OSI broadcast status in SIB 1. In addition, in the network energy saving (i.e., on-demand SIB1, OD-SIB 1)) scenario, the network energy saving (network ENERGY SAVING, NES) cell transmits SIB1 On demand, when the terminal in connection state needs to obtain OSI, SIB1 is requested first, after obtaining the requested SIB1, it may be known that the OSI of interest is not broadcast according to the configuration of SIB1 (in the case that SIB1 is a request On demand, OSI is more likely to be requested On demand), then the terminal needs to transmit two requests to obtain the OSI of interest, which increases the time delay and power consumption of the terminal for requesting OSI. The problem also exists for terminals in RRC IDLE/INACTIVE state. It follows that when the terminal acquires the needed OSI, it may need to request SIB1 first, which increases the delay and power consumption for acquiring OSI. Disclosure of Invention The embodiment of the application provides an information acquisition method, an information indication device and communication equipment, which can solve the problems of longer time delay and larger power consumption of acquiring OSI by a terminal in the prior related art.
