An electronic apparatus in a wireless communications system, and a mobility measurement method. The electronic apparatus includes a communications device and a mobility measurement device. The communication device is configured to separately perform dual-connection communication with two connection nodes by different carriers. The mobility measurement device is configured to perform mobility measurement, for determining a connection switching mode, on the connection nodes in the dual connections in a case in which connection service quality of at least one of the current dual connection nodes is lower than a preset level. The mobility measurement device is further configured to determine a reporting mode of a mobility measurement result according to the measurement condition of at least one of the current dual connection nodes.
