Description

TECHNICAL FIELD The disclosure relates to a field of communications, and particularly to a method, an apparatus, a device and a storage medium for a drive test. BACKGROUND Drive test may reflect a network condition of a mobile communication system, and may play a direct role in measuring and evaluating network performance indicators, which helps pinpoint the problems of the network. Conventional network optimization requires drive test personnel to move and measure as much as possible within a network coverage range, and to collect network data such as level and signal quality using a drive test instrument. Third generation partnership project (3 GPP) defines the minimization of drive tests (MDT) technology. The MDT technology is to acquire related parameters required by network optimization through a measurement report reported by a terminal. In the related art, the MDT is activated by operation administration maintenance (OAM). WO2015137656A1 discloses a method and apparatus for reconfiguring multimedia broadcast multicast service (MBMS) minimization of drive test (MDT) in a wireless communication system. A user equipment (UE) receives a value tag for MBMS-MDT, and determines whether to perform MBMS-MDT reconfiguration by comparing the received value tag for MBMS-MDT with a stored value tag for MBMS-MDT. If the received value tag for MBMS-MDT and the stored value tag for MBMS-MDT are different from each other, the UE performs the MBMS-MDT reconfiguration. Alternatively, if a paging message includes an indicator of modification of the MBMS-MDT configuration, the UE acquires the MBMS-MDT configuration and performs the MBMS-MDT reconfiguration.
