Information processing device, communication device, and information processing method

1 . An information processing device comprising a control unit that:

determines, for a communication path, a communication period in which wireless communication and wired communication are performed by using the communication path between terminal devices connected to different base stations, the communication path including a wireless section between a terminal device and a base station and a wired section between the different base stations; and

notifies the terminal device and the base station of information on the communication period that has been determined.

2 . The information processing device according to claim 1 ,

wherein the control unit determines the communication period based on a communication allowed time in accordance with an application and a number of the communication path.

3 . The information processing device according to claim 1 ,

wherein the communication path includes a relay station that relays communication between different base stations.

4 . The information processing device according to claim 3 ,

wherein the control unit determines timing when at least one of the base station and the relay station starts the wired communication in accordance with propagation delay of the wired section.

5 . The information processing device according to claim 3 ,

wherein the terminal device, the base station, and the relay station are mutually time-synchronized.

6 . The information processing device according to claim 3 ,

wherein the control unit:

determines a total wired period that is allowed to be used in the wired communication among communications between a plurality of terminal devices in accordance with a communication allowed time, signal processing times in the terminal device, the base station, and the relay station, and a communication time in the wireless section; and

determines, for each of the plurality of terminal devices, an individual wired period that is allowed to be used in the wired communication in accordance with the total wired period and a number of the plurality of terminal devices.

7 . The information processing device according to claim 3 ,

wherein the control unit:

determines a total wireless period that is allowed to be used in the wireless communication among the communications between the plurality of terminal devices in accordance with a communication allowed time, signal processing times in the terminal device, the base station, and the relay station, and a communication time in the wired section; and

determines, for each of the plurality of terminal devices, a wireless resource that is allowed to be used in the wireless communication in accordance with the total wireless period and a number of the plurality of terminal devices.

8 . The information processing device according to claim 1 ,

wherein, when a communication time in a case where the terminal device performs communication in the communication period that has been determined is longer than a communication time requested in an application, the control unit redetermines the communication period.

9 . The information processing device according to claim 8 ,

wherein, when redetermining the communication period, the control unit changes wireless information to be used in the wireless section, and redetermines the communication period.

10 . The information processing device according to claim 1 ,

wherein the terminal device uses the communication path as the communication path of traffic in which low delay is required.

11 . A communication device comprising a control unit that:

acquires information on a communication period in which wireless communication and wired communication are performed by using a communication path between terminal devices connected to different base stations, the communication path including a wireless section between a terminal device and a base station and a wired section between the different base stations, the communication period having been determined for the communication path; and

performs communication in the communication period that has been acquired.

12 . An information processing method comprising:

determining, for a communication path, a communication period in which wireless communication and wired communication are performed by using the communication path between terminal devices connected to different base stations, the communication path including a wireless section between a terminal device and a base station and a wired section between the different base stations; and

notifying the terminal device and the base station of information on the communication period that has been determined.
