When it is determined that a terminal is present in a femtocell, a request signal for requesting a network-side device to change a cycle of a cyclic operation is transmitted from the terminal to the network-side device, via a communication path that includes the femtocell. In response to the request signal, the network-side device changes the cycle of the cyclic operation, and transmits, to the terminal, a response signal for notifying of a change to the cycle, via the same communication path. In response to the response signal, the terminal changes the cycle of the cyclic operation. |
