Abstract

Claims (27)

1. A communication control device comprising:

control circuitry configured to cause a second communication device to generate a switching response frame indicating a response of connection switching that is to be transmitted to a communication terminal configured to switch a connection destination from a first communication device to the second communication device, on a basis of information regarding connection between the first communication device and the communication terminal;

a transmitter configured to transmit a switching request frame including the information regarding connection and indicating a request of connection switching, to the second communication device,

wherein the control circuitry causes the second communication device to generate the switching response frame on a basis of the switching request frame; and

a receiver configured to receive a transition query frame indicating a query of connection transition that is transmitted from the communication terminal,

wherein the control circuitry generates a switching query frame indicating a query of connection switching, on a basis of the transition query frame.

2. The communication control device according to claim 1 ,

wherein the information regarding connection includes at least one of a common key generated by device authentication, a MAC address of the first communication device, or a MAC address of the communication terminal.

3. The communication control device according to claim 1 , further comprising

a transmitter configured to transmit the switching response frame to the communication terminal.

4. The communication control device according to claim 1 , further comprising

a receiver configured to receive a switching query frame including the information regarding connection and indicating a query of connection transition that is transmitted from the first communication device,

wherein the control circuitry generates the switching request frame on a basis of the switching query frame.

5. The communication control device according to claim 4 ,

wherein the control circuitry determines the second communication device on a basis of the switching query frame.

6. A communication control method performed by a communication control device and comprising:

causing a second communication device to generate a switching response frame indicating a response of connection switching that is to be transmitted to a communication terminal configured to switch a connection destination from a first communication device to the second communication device, on a basis of information regarding connection between the first communication device and the communication terminal;

transmitting a switching request frame including the information regarding connection and indicating a request of connection switching, to the second communication device,

wherein the switching response frame is generated on a basis of the switching request frame; and

receiving a transition query frame indicating a query of connection transition that is transmitted from the communication terminal,

wherein a switching query frame indicating a query of connection switching is generated on a basis of the transition query frame.

7. A non-transitory computer product containing instructions for causing a communication control device to perform a method, the method comprising:

causing a second communication device to generate a switching response frame indicating a response of connection switching that is to be transmitted to a communication terminal configured to switch a connection destination from a first communication device to the second communication device, on a basis of information regarding connection between the first communication device and the communication terminal;

transmitting a switching request frame including the information regarding connection and indicating a request of connection switching, to the second communication device,

wherein the switching response frame is generated on a basis of the switching request frame; and

receiving a transition query frame indicating a query of connection transition that is transmitted from the communication terminal,

wherein a switching query frame indicating a query of connection switching is generated on a basis of the transition query frame.
