(1): According to an aspect of the present invention, there is provided a communication device including: 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.

(2): In the above-described aspect (1), each of the plurality of access points is connected to the base station and the connection adjuster generates a connection release request for releasing the connected state associated with the access point when the access point whose connected state is released is determined and causes the generated connection release request to be transmitted from the communicator to the base station.

(3): In the above-described aspect (1), the communication device further includes a third acquirer configured to acquire a communication requirement for each piece of the vehicle information, wherein the connection adjuster determines the access point whose connected state is released on the basis of the communication requirement acquired by the third acquirer.
