Abstract

The present disclosure provides a radio communication device including a communication processor that connects to at least one first radio terminal through radio communication using beam forming, an information sharer that acquires first connection information including a connection situation of one or more second radio terminals connected to a second radio communication device, a switch determiner that determines whether or not to switch a connection destination of the at least one first radio terminal from the radio communication device to the second radio communication device in reference to the first connection information, and a connection switcher that, when the switch determiner determines to switch the connection destination, switches the connection destination of the at least one first radio terminal from the radio communication device to the second radio communication device.

First claim

What is claimed is:

1 . A radio communication device comprising:
a communication processor that connects to one or more first radio terminals through radio communication using beam forming; an information sharer that acquires first connection information including a connection situation of one or more second radio terminals connected to a second radio communication device; a switch determiner that determines whether or not to switch a connection destination of the one or more first radio terminals from the radio communication device to the second radio communication device in reference to the first connection information; and a connection switcher that, when the switch determiner determines to switch the connection destination, switches the connection destination of the one or more first radio terminals from the radio communication device to the second radio communication device.

2 . The radio communication device according to claim 1 , wherein
when the switch determiner determines to switch the connection destination, the connection switcher causes the second radio communication device to perform a beam forming protocol for the one or more first radio terminals and, after the beam forming protocol succeeds, switches the connection destination of the one or more first radio terminals from the radio communication device to the second radio communication device.

3 . The radio communication device according to claim 1 , wherein
the information sharer acquires second connection information that includes a connection situation of the one or more first radio terminals connected to the radio communication device, and the switch determiner determines whether or not to switch the connection destination of the one or more first radio terminals from the radio communication device to the second radio communication device in reference to the second connection information.

4 . The radio communication device according to claim 3 , wherein
the first connection information includes at least one of the number of the one or more second radio terminals, and communication quality between the second radio communication device and the one or more second radio terminals, and the second connection information includes at least one of the number of the one or more first radio terminals, and communication quality between the radio communication device and the one or more first radio terminals.

5 . The radio communication device according to claim 1 , wherein
the information sharer acquires third connection information that includes a connection situation of one or more third radio terminals connected to a third radio communication device, the switch determiner determines whether or not to switch the connection destination of the one or more first radio terminals from the radio communication device to the second radio communication device or the third radio communication device in reference to the first connection information and the third connection information, and when the switch determiner determines to switch the connection destination, the connection switcher switches the connection destination of the one or more first radio terminals from the radio communication device to the second radio communication device or the third radio communication device.

6 . The radio communication device according to claim 5 , wherein
the first connection information includes the number of the one or more second radio terminals, the third connection information includes the number of the one or more third radio terminals, when the switch determiner determines to switch the connection destination and the number of the one or more second radio terminals is smaller than the number of the one or more third radio terminals, the switch determiner determines to switch the connection destination from the radio communication device to the second radio communication device, and when the switch determiner determines to switch the connection destination and the number of the one or more third radio terminals is smaller than the number of the one or more second radio terminals, the switch determiner determines to switch the connection destination from the radio communication device to the third radio communication device.

7 . The radio communication device according to claim 3 , wherein
the second information includes communication quality between the radio communication device and the one or more first radio terminals, and the switch determiner determines to switch the connection destination of one of the first radio terminals that is lowest in the communication quality of the one or more first radio terminals.

8 . The radio communication device according to claim 3 , wherein
the information sharer transmits the second connection information to the second radio communication device.

9 . A communication control method of a radio communication device that connects to one or more first radio terminals through radio communication using beam forming, the method comprising:
acquiring connection information that includes a connection situation of one or more second radio terminals connected to a second radio communication device; determining whether or not to switch a connection destination of the one or more first radio terminals from the radio communication device to the second radio communication device in reference to the first connection information; and when determining to switch the connection destination, switching the connection destination of the one or more first radio terminals from the radio communication device to the second radio communication device.
