Abstract: A communication device (40) is provided. A communication device (40) includes a transceiver (41) and a processor (43). The processor (43) receives, via the transceiver (41), execution trigger information regarding a trigger for executing a handover. After executing a detachment procedure on a first non-terrestrial station (30) having a first cell, the processor (43) performs an evaluation for the trigger using the execution trigger information. The processor (43) connects to a second non-terrestrial station (30) having a second cell different from the first cell on a basis of the evaluation.
