In the present embodiment, the terminal device mounted on a vehicle performs wireless communication to perform traveling control of the vehicle, such as remote driving. However, this is merely an example, and an arbitrary terminal device having a wireless function of being able to connect to a cellular communication network such as a smart phone, a mobile phone, a personal computer, and the like may be used. Furthermore, an example in which one base station forms one cell is shown, but generally, one base station may form a plurality of cells.
In the example of FIG. 1, the terminal device 111 exists within a range of the cell 121 formed by the base station 101, and connects to the base station 101 to perform wireless communication. The terminal device 112 exists within a range of the cell 124 formed by the base station 104, and connects to the base station 104 to perform wireless communication. Although the position of the terminal device 112 is also within the range of the cell 123 formed by the base station 103, the terminal device 112 may connect to the base station 104 due to reasons such as, for example, the wireless or radio quality of the radio signal from the base station 104 being higher than the radio quality of the radio signal from the base station 103.
