The switch determiner 330 determines whether or not all of the connection switch determination condition, the switch source candidate terminal condition, and the switch destination candidate device condition are satisfied by referring to the integrated terminal management table 550 (see FIG. 7) that the information sharer 320 retains.

When all of the three conditions are satisfied, the switch determiner 330 determines the connecting terminal 400 that satisfies the switch source candidate terminal condition as the switch source candidate terminal 400 and determines one of the other devices 300 that satisfies the switch destination candidate device condition as the switch destination candidate device 300. The switch determiner 330 outputs the switch determination information indicating the result of the determination to the connection switcher 340.

For example, the terminal ID 542 of the first terminal management table 540₁ (see FIG. 7) indicates that the first radio communication device 300₁ is connected to three radio terminals, that is, the first to third radio terminals 400₁ to 400₃ (STA1 to STA3). Accordingly, the switch determiner 330 of the first radio communication device 300₁ determines that the connection switch determination condition is satisfied.
