摘要

The base station 13 transmits history information indicating whether a predetermined coverage improvement process has been executed in the previous communication of the M2M (Machine-to-machine) terminal 11 to the M2M terminal 11 or the core network 14 As shown in Fig. The base station 13 also controls the communication using the predetermined coverage improvement processing between the M2M terminal 11 and the base station 13 based on the history information received from the M2M terminal 11 or the core network 14 . This makes it possible to improve the efficiency of determination as to whether or not to apply the special coverage improvement processing to the M2M terminal.
