Abstract: The present disclosure relates to code scanning methods based on vehicle-mounted cameras. One example method includes collecting a first image by using a vehicle-mounted camera, parsing a target encoding pattern included in the first image, and when no parsing information is obtained, collecting, based on image data obtained by the vehicle-mounted camera, another image that is close to the first image in a time relationship for parsing to attempt to obtain parsing information in the target encoding pattern.

Abstract: Embodiments of the present invention provide a cell handover method, a base station and a system, which relate to the field of wireless communications technologies. The method includes: determining, by a source eNB according to uplink RSRP of a UE in a serving cell and a target cell, whether to hand over the UE from the serving cell to the target cell; and if yes, acquiring UE parameters including TA of the UE in the target cell, and sending UE data and the UE parameters to a target eNB, where the TA is used for uplink synchronization between the target eNB and the UE.
