Further, the information sharer 320 acquires information on the other device 300 indicating a situation of the connection between the other device 300 and the radio terminal 400 as the other device information, which is also referred to as the first connection information, from the other device 300 through the communication processor 310 and records the other device information that has been acquired.

Each of the self device information and the other device information indicates the situation of the connection between the radio terminal 400 and one of the radio communication devices 300 as the connection information. Accordingly, the self device information and the other device information are collectively referred to as the “device information” when suitable. The information sharer 320 causes the device information to be recorded in, for example, a terminal management table stored in the information sharer 320. The terminal management table is described in detail below.

The switch determiner 330 determines whether or not to switch the connection destination of the radio terminal 400 currently connecting to the radio communication device (self radio communication device) 300, which is also referred to as the “connecting terminal” 400 hereinafter when suitable, to the other device 300. At this time, the switch determiner 330 determines of which connecting terminal 400 the connection destination is switched and to which one of the other devices 300 the connection destination of the determined connecting terminal 400 is switched. Criteria in determining the switch is described in detail below.
