Data is transferred between a DECT terminal and an LTE base station. A base unit includes a DECT communication unit and an LTE communication unit, the DECT communication unit performing DECT communication with a DECT terminal, and the LTE communication unit transmitting and receiving data with the DECT communication unit and performing LTE communication with an LTE carrier gateway through an LTE base station. The DECT communication unit, in a case where an adjacent frequency bandwidth that is adjacent to one of DECT communication sub-bands is used in the LTE communication, controls the DECT communication to be performed by using the other sub-band.

Communication device

Data is transferred between a DECT terminal and an LTE base station. A base unit includes a DECT communication unit and an LTE communication unit, the DECT communication unit performing DECT communication with a DECT terminal, and the LTE communication unit transmitting and receiving data with the DECT communication unit and performing LTE communication with an LTE carrier gateway through an LTE base station. The DECT communication unit transmits a connection verification request to the LTE communication unit in order to verify a connection state of an LTE link with the LTE carrier gateway. The LTE communication unit transmits a connection verification response to the DECT communication unit in response to the connection verification request in a case where an LTE link is connected. The DECT communication unit, in a case where the DECT communication unit receives a DECT connection request for requesting connection of an DECT link from the DECT terminal and receives the connection verification response from the LTE communication unit, transmits a DECT connection response to the DECT terminal in response to the DECT connection request.
