FIG. 3 is a diagram showing an example of content of the communication management information 52. The communication management information 52 is, for example, information in which a wireless communication scheme and connected vehicle information are associated with a communication mode. The communication mode includes, for example, communication in the P cell by the base station 10, communication in the S cell by the access point AP connected to the base station 10, and the like. The wireless communication scheme is a communication scheme set for each communication mode. As shown in the example of FIG. 3, the wireless communication schemes of the base station 10 and the access points AP1 and AP3 are “4G” and the wireless communication scheme of the access point AP2 is “5G.” The wireless communication scheme may be set by, for example, a server device SV and information may be acquired from the access points AP1 to AP3. For example, the connected vehicle information is identification information for identifying a communication mode of the base station 10, the access point AP, or the like and the vehicle M in which the communication device 100 in a connected state is mounted. In the communication management information 52, instead of (or in addition to) the connected vehicle information, identification information (connected communication terminal information) for identifying the communication device 100 in the connected state may be associated with the communication mode.
