Abstract

A wireless communication device installed in a flying vehicle, includes a wireless communication part configured to receive a wireless signal transmitted from a wireless base station, a cell counter configured to count the number of cells corresponding to wireless base stations identified by wireless signals received by the wireless communication part, and a communication controller configured to change a communication party selecting method to select the wireless base station serving as a communication party from among a plurality of wireless base stations serving as communication party candidates when an increment or a decrement of a unit-time cell count representing the counting result of the cell counter in a predetermined time is equal to or more than a predetermined threshold.

First claim

The invention claimed is:

1. A wireless communication device installed in a flying vehicle, the wireless communication device comprising:
a wireless communication part configured to receive a wireless signal transmitted from a wireless base station; and
a communication controller configured to change a communication party selecting method by changing a handover parameter for controlling handover between a plurality of wireless base stations serving as communication party candidates, in accordance with an altitude of the wireless communication device,
wherein the communication controller is configured to change the handover parameter in accordance with the altitude, in response to a successful authentication performed by the wireless base station connected to the wireless communication device and having an authentication function that authenticates the wireless communication device.

2. The wireless communication device according to claim 1 , wherein the handover parameter includes a trigger time.

3. The communication control method according to claim 2 , wherein the trigger time is a time to trigger (TTT).

4. The wireless communication device according to claim 1 , wherein
the wireless communication device is connected to a network that provides the changed handover parameter according to the altitude to the wireless communication device, in a case where authentication performed by the wireless base station is successful.

5. The wireless communication device according to claim 1 , wherein
the communication controller is configured to acquire the changed handover parameter according to the altitude, in a case where authentication performed by the wireless base station is successful.

6. The wireless communication device according to claim 1 , wherein
the communication controller is allowed to acquire the changed handover parameter, in response to successful authentication performed by the wireless base station.

7. The wireless communication device according to claim 1 , wherein
the communication controller is configured to change the communication party selecting method by changing the handover parameter in accordance with a change in the altitude at which the wireless communication device is positioned.

8. The wireless communication device according to claim 1 , wherein the communication controller is configured to change the communication party selecting method by changing the handover parameter in accordance with an increase in the altitude at which the wireless communication device is positioned.

9. The wireless communication device according to claim 1 , wherein the communication controller is configured to change the communication party selecting method by changing the handover parameter in a case where the wireless communication device is determined to be positioned at the altitude in a sky.

10. A communication control method for a wireless communication device installed in a flying vehicle, the communication control method comprising:
receiving a wireless signal transmitted from a wireless base station; and
changing a communication party selecting method by changing a handover parameter for controlling handover between a plurality of wireless base stations serving as communication party candidates, in accordance with an altitude of the wireless communication device,
wherein in the changing, the handover parameter is changed in accordance with the altitude, in response to a successful authentication performed by the wireless base station connected to the wireless communication device and having an authentication function that authenticates the wireless communication device.

11. The communication control method according to claim 10 , wherein the handover parameter includes a trigger time.

12. The communication control method according to claim 10 , wherein the trigger time is a time to trigger (TTT).

13. The communication control method according to claim 10 , wherein
the wireless communication device is connected to a network that provides the changed handover parameter according to the altitude to the wireless communication device, in a case where authentication performed by the wireless base station is successful.

14. The communication control method according to claim 10 , wherein
the changing of the communication party selecting method includes acquiring the changed handover parameter according to the altitude, in a case where authentication performed by the wireless base station is successful.

15. The communication control method according to claim 10 , wherein the changing of the communication party selecting method comprises:
allowing an acquisition of the changed handover parameter, in response to successful authentication performed by the wireless base station connected to the wireless communication-device and having an authentication function that authenticates the wireless communication-device.

16. The communication control method according to claim 10 , wherein the changing of the communication party selecting method comprises:
changing the handover parameter in accordance with a change in the altitude at which the wireless communication device is positioned.

17. The communication control method according to claim 10 , wherein the changing of the communication party selecting method comprises:
changing the handover parameter in accordance with an increase in the altitude at which the wireless communication device is positioned.

18. The communication control method according to claim 10 , wherein the changing of the communication party selecting method comprises:
changing the handover parameter in a case where the wireless communication device is determined to be positioned at the altitude in a sky.
