Japanese Patent JP6798582
Kind Code:
B2
Abstract:
A Machine-to-machine (M2M) terminal (11) is configured to receive a first notification from a base station (13) and to transmit a second notification to the base station (13) when establishing a radio connection with the base station (13) after reception of the first notification or while performing a procedure for establishing a bearer between the M2M terminal (11) and a core network (14) after reception of the first notification. The first notification indicates whether specific coverage enhancement processing is supported in a cell (130) of the base station (13) in which the M2M terminal (11) is located. The second notification indicates that the specific coverage enhancement processing is required or being executed by the M2M terminal (11). It is thus possible to provide an improvement to allow the M2M terminal to determine necessity of special coverage enhancement processing for M2M terminals.
