摘要

According to an aspect, a communication device includes a communicator configured to perform communication with a base station and a plurality of access points having narrower communication ranges than the base station, a first acquirer configured to acquire vehicle information from in-vehicle equipment, a second acquirer configured to acquire information about communication quality for each of the plurality of access points, and a connection adjuster configured to release a connected state associated with a determined access point when the access point whose connected state is released is determined on the basis of the information about the communication quality acquired by the second acquirer if communication with the plurality of access points by the communicator is in the connected state.

說明書

Next, the vehicle M transmits the corresponding vehicle information for each selected access point. For example, when the vehicle information has been transmitted from the vehicle M to the access point AP2 (step S120), the access point AP2 transmits the received vehicle information to the base station 10 (step S122). The base station 10 receives the vehicle information transmitted from the access point AP2 and outputs the received vehicle information to the server device SV (step S124). The server device SV receives the vehicle information transmitted from the base station 10, stores the received vehicle information in the storage, performs various types of processes on the vehicle information, and transmits provision information to the base station 10 when there is information to be provided to the vehicle M (for example, driving control information) (step S126). The base station 10 receives the information transmitted from the server device SV and transmits the received information to the access point AP2 (step S128). The access point AP2 receives the information transmitted from the base station 10 and transmits the received information to the vehicle M (step S130).
