Abstract

A communication system includes: a first communication apparatus configured to control a first wireless communication and a second wireless communication different from the first wireless communication; a second communication apparatus configured to communicate using the second communication; and a third communication apparatus configured to perform data communication with the first communication apparatus via the first wireless communication or the second wireless communication, wherein the third communication apparatus transmits to the first communication apparatus a control message that includes an available address of the third wireless communications apparatus used in the second wireless communication, the first communication apparatus notifies the second communication apparatus of the available address of the third communication apparatus, and the second communication apparatus communicate with the third communication apparatus using the address.

Claims (31)

1. A wireless communications system comprising:

a first communications apparatus configured to control a first wireless communication and a second wireless communication different from the first wireless communication;

a second communications apparatus configured to perform the second wireless communication; and

a third communications apparatus configured to perform data communication with the first communications apparatus via the first wireless communication or the second wireless communication, wherein

the third communications apparatus is further configured to:

receive from the second communications apparatus, data and identification information that can be used to identify a bearer of the data, the data being transmitted to the third communications apparatus by the first communications apparatus via the second communications apparatus, and the identification information being attached by the second communications apparatus, and

identify the bearer corresponding to the data according to the identification information.

2. The wireless communications system according to claim 1 , wherein

the third communications apparatus is further configured to transmit a control message that includes an available address of the third communications apparatus in the second wireless communication,

the first communications apparatus is further configured to notify the second communications apparatus of the available address acquired from the control message, and

the second communications apparatus is further configured to communicate with the third communications apparatus using the available address.

3. A mobile station configured to communicate with a first communications apparatus via a first wireless communication or a second wireless communication different from the first wireless communication, the mobile station comprising:

a receiver configured to receive, using the second wireless communication and from a second communications apparatus different from the first communications apparatus and communication with the mobile station, data and identification information that can be used to identify a bearer of the data, the data being transmitted to the mobile station by the first communications apparatus via the second communications apparatus, and the identification information being attached by the second communications apparatus ; and

a controller configured to identify the bearer corresponding to the data according to the identification information.

4. The mobile station according to claim 3 , further comprising

a transmitter configured to transmit a control message that includes an available address of the mobile station in the second wireless communication.

5. The mobile station according to claim 4 , wherein

the receiver is further configured to receive from the first communications apparatus, a request signal for requesting the available address, and

the transmitter is configured to transmit the control message according to the request signal.

6. A communication apparatus comprising:

processor circuitry configured to control a first wireless communication and a second wireless communication different from the first wireless communication;

a transmitter configured to transmit data to which identification information that can be used to identify a bearer of the data is to be attached by a second communications apparatus, to a third communications apparatus via the second communications apparatus.

7. The communication apparatus according to claim 6 , further comprising:

a receiver configured to receive from the third communications apparatus, a control message that includes an available address of the third communications apparatus in the second wireless communication.

8. The communications apparatus according to claim 6 , wherein

the processor circuitry is further configured to control the transmitter to transmit, via an adaptation sublayer, the data to which a sequence number is added through a processing of a convergence layer for performing the first wireless communication.

9. The communications apparatus according to claim 6 , wherein

the data is transmitted from the second communications apparatus to the third communications apparatus via the second communication , and

the bearer corresponding to the data is identified by the third communications apparatus according to the identification information received by the third communications apparatus.

10. The communications apparatus according to claim 6 , wherein

the transmitter is further configured to transmit configuration information for aggregating the first wireless communication and the second wireless communication.
