Abstract

An electronic communication device comprises a first transceiver capable of a bi-directional communication session on a first communication medium; a second transceiver capable of a bi-directional communication session on a second communication medium; and a control logic coupled to the first transceiver and the second transceiver and capable of implementing a convergence layer, wherein the control logic is configured to receive, from the first transceiver, a first signal; and cause, in response to the first signal, data received and transmitted by the first transceiver on the first communication medium as part of a communication session to be received and transmitted instead by the second transceiver on the second communication medium.

Claims

1. An electronic communication device comprising:

a first transceiver capable of a bi-directional communication session on a first communication medium;

a second transceiver capable of a bi-directional communication session on a second communication medium;

a convergence layer; and

a control logic coupled to the first transceiver and the second transceiver and capable of implementing the convergence layer, wherein the control logic is configured to

receive, from the first transceiver, a first signal; and

cause, through the convergence layer, in response to the first signal, data received and transmitted by the first transceiver on the first communication medium as part of a communication session to be received and transmitted instead by the second transceiver on the second communication medium;

wherein the convergence layer is configured to conceal from a routing layer at least one of

information related to the first signal, and

information related to the data being received and transmitted on the second communication medium.

2. The device of claim 1, wherein the control logic is further configured to

receive, from the first transceiver or the second transceiver, a second signal;

and

cause, in response to the second signal, data received and transmitted by the second transceiver on the second communication medium to be received and transmitted instead by the first transceiver on the first communication medium.

3. The device of claim 2, wherein the control logic is configured to cause, through the convergence layer, the data received and transmitted by the second transceiver on the second communication medium to be received and transmitted instead by the first transceiver on the first communication medium.

4. The device of claim 1, wherein

the first communication medium and the second communication medium are one of a radio frequency link and a power line communication link, and

the first communication medium and the second communication medium are not the same.

5. The device of claim 1, wherein the first communication medium and the second communication medium are the same.

6. A method for electronic communication comprising:

providing a first transceiver capable of a bi-directional communication session on a first communication medium, a second transceiver capable of a bi-directional communication session on a second communication medium, and a control logic coupled to the first transceiver and the second transceiver and capable of implementing a convergence layer;

receiving, by the control logic from the first transceiver, a first signal; and

causing, through the convergence layer, by the control logic in response to the first signal, data received and transmitted by the first transceiver on the first communication medium as part of a communication session to be received and transmitted instead by the second transceiver on the second communication medium, wherein the convergence layer is configured to conceal from a routing layer at least one of;

information related to the first signal, and

information related to the data being received and transmitted on the second communication medium.

7. The method of claim 6, further comprising:

receiving, by the control logic from the first transceiver or the second transceiver, a second signal; and

causing, by the control logic in response to the second signal, data received and transmitted by the second transceiver on the second communication medium to be received and transmitted instead by the first transceiver on the first communication medium.

8. The method of claim 7, wherein the control logic is configured to cause, through the convergence layer, the data received and transmitted by the second transceiver on the second communication medium to be received and transmitted instead by the first transceiver on the first communication medium.

9. The method of claim 6, wherein

the first communication medium and the second communication medium are one of a radio frequency link and a power line communication link, and

the first communication medium and the second communication medium are not the same.

10. The method of claim 6, wherein the first communication medium and the second communication medium are the same.

11. The method of claim 6, wherein the first communication medium and the second communication medium are accessed in a single device.
