  • Publication number: 20210007043
    Abstract: The present disclosure relates to a method and an apparatus for stopping an SI request, user equipment, a base station, and a computer readable storage medium. The method for stopping an SI request includes: if a first system information block (SIB1) indicates that an SI to be acquired by a UE is not being broadcast, sending an SI request to the base station by means of a first message (MSG1) or a third message (MSG3); during waiting for the base station to return an SI response, if an updated SIB1 is acquired and the updated SIB1 indicates that the requested SI is being broadcast, stopping the SI request procedure. In the embodiments of the present disclosure, the SI request can be terminated in advance, thereby reducing wasted UE power consumption and avoiding unnecessary operations.

    Abstract: The present disclosure relates to an information recording method. The method is applicable to user equipment, and includes: receiving indication information from a base station, wherein the indication information includes mode indication information indicating a mode for recording Minimized Driving Test (MDT) information; and when the user equipment is in an inactive state, recording the MDT information according to the mode indication information. According to examples of the present disclosure, the user equipment may record the MDT information when it is in the inactive state, such that the user equipment transmits the MDT information recorded in the inactive state to the base station when the user equipment establishes or restores a communication connection with the base station later. Thus, the base station can determine various failures of the user equipment in the inactive state, thereby facilitating the base station to perform troubleshooting accurately.
