Title: BASE STATION, TERMINAL, COMMUNICATION SYSTEM, AND COMMUNICATION METHOD
Abstract:
A first base station (120) is provided with a receiving unit (121) and a control unit (122). The receiving unit (121) receives, from a terminal (110) connected to a first cell of the local station, a value that indicates discrepancy between the wireless signal transmit timing of the terminal (110) and the reference timing of a second cell different from the first cell. The control unit (122) selects a handover method on the basis of the value received by the receiving unit (121) from a first handover method that includes a random access procedure and a second handover method that does not include at least a portion of the random access procedure. The control unit (122) exercises control for switching a connection destination of the terminal (110) to the second cell by the selected handover method.
