Communication control device and communication control method

Abstract

Provided is a communication control device that is installed in a moving body, the communication control device including: a detecting means for detecting, on the basis of image data in which the direction of a base station to which the moving body connects is captured, a blocking object between the moving body and the base station to which the moving body connects; and a predicting means for predicting, on the basis of the position and the size of the detected blocking object, changes in communication quality of a first wireless network utilized by the moving body for external communication.

Claims

1. A communication control device mounted on a mobile body, comprising: detection means for detecting an obstruction between the mobile body and the base station to which the mobile body is connected, based on image data of the direction of the base station to which the mobile body is connected; A prediction means predicts changes in the communication quality of the first wireless network used by the mobile body for communication with the outside, based on the position and size of the detected obstruction. The system includes switching means that switches to communication using a second wireless network different from the first wireless network based on the communication quality of the first wireless network, The prediction means further refers to map information and predicts changes in the communication quality of the first wireless network based on the length of tunnels located ahead of the moving object. The switching means further refers to the map information and, based on the presence or absence of a base station in the tunnel, switches from the connected first wireless network to communication using the second wireless network via the base station in the tunnel. Communication control device.

2. The communication control device according to claim 1, wherein the switching means switches to communication using the second wireless network when the deterioration of the communication quality of the first wireless network continues for a predetermined period of time.

3. The communication control device according to claim 1 or 2, wherein the frequency band used in the first wireless network is a frequency band that is more susceptible to the influence of obstacles than the frequency band used in the second wireless network.

4. The communication control device according to any one of claims 1 to 3, wherein the prediction means further predicts the period during which the deterioration of the communication quality of the first wireless network continues, based on the relative speed between the moving object and the shielding object.

5. The communication control device according to any one of claims 1 to 4, wherein the detection means detects other moving objects that are moving around the moving object as the shielding object.

6. Based on image data capturing the direction of the base station to which the mobile body is connected, an obstruction between the mobile body and the base station to which the mobile body is connected is detected. Based on the location and size of the detected obstruction, the change in the communication quality of the first wireless network used by the mobile body for communication with the outside is predicted. In predicting changes in the communication quality of the first wireless network, further, by referring to map information and based on the length of the tunnel located ahead of the moving object, the changes in the communication quality of the first wireless network are predicted. Based on the communication quality of the first wireless network, the system switches to communication using a second wireless network different from the first wireless network. In switching to communication using the second wireless network, the system further refers to the map information and, based on the presence or absence of a base station in the tunnel, switches from the currently connected first wireless network to communication using the second wireless network via the base station in the tunnel. Communication control method.
