Abstract

A method for communication between first and second coordinator-based wireless networks connected through a backbone network is provided. The method includes receiving a frame indicating data transmission containing information needed for remote channel time allocation (CTA) from a repeater connecting the second coordinator-based wireless network with the backbone network, sending a remote CTA frame in order for the repeater to request CTA from the coordinator within the second coordinator-based wireless network, and receiving a data frame originated from the first coordinator-based wireless network and then provided by the repeater during assigned channel time.

Claims

1. A method for communication in a coordinator-based wireless network, the method comprising:

obtaining information needed for channel time allocation (CTA) from a frame indicating data transmission received from a sending device;

sending a remote CTA request frame to the sending device in order for the sending device to request the CTA from a coordinator within the wireless network for data transmission; and

receiving a data frame transmitted by the sending device during channel time allocated by the coordinator.

2. The method of claim 1, wherein frames being transmitted from the wireless network are compliant with the IEEE 802.15.3 standard.

3. A method for communication in a coordinator-based wireless network, the method comprising:

sending a frame indicating data transmission containing information needed for channel time allocation (CTA) to a target device, in order for the target device to generate a remote CTA request frame;

receiving the remote CTA request frame from the target device;

requesting CTA from a coordinator within the wireless network for data reception, according to the remote CTA request; and

sending a data frame to the target device during channel time assigned by the coordinator.

4. The method of claim 3, wherein frames being transmitted from the wireless network are compliant with the IEEE 802.15.3 standard.

5. A method for communication between first and second coordinator-based wireless networks connected through a backbone network, the method comprising:

sending a frame indicating data transmission from a sending device in the first coordinator-based wireless network to a repeater connecting the first coordinator-based wireless network with the backbone network in order for a target device within the second coordinator-based wireless network to request remote channel time allocation (CTA); and

sending a frame to be destined for the target device from the sending device to the repeater after sending the frame indicating data transmission.

6. The method of claim 5, wherein the frame sent by the sending device is compliant with the IEEE 802.15.3 standard and contains additional information needed to be transmitted to the target device through the backbone network.

7. The method of claim 6, wherein the additional information is a unique identifier of the second coordinator-based wireless network.

8. The method of claim 6, wherein the additional information is a unique identifier of the target device.

9. A method for communication between first and second coordinator-based wireless networks connected through a backbone network, the method comprising:

receiving a frame indicating data transmission containing information needed for remote channel time allocation (CTA) from a repeater connecting the second coordinator-based wireless network with the backbone network;

sending a remote CTA frame in order for the repeater to request CTA from the coordinator within the second coordinator-based wireless network; and

receiving a data frame originated from the first coordinator-based wireless network and then provided by the repeater during assigned channel time.

10. The method of claim 9, wherein the frames being transmitted from or received in the wireless network are compliant with the IEEE 802.15.3 standard.

11. A computer-readable recording storage having a computer readable program recorded therein for causing a computer to implement a method for communication in a coordinator-based wireless network, the method comprising:

obtaining information needed for channel time allocation (CTA) from a frame indicating data transmission received from a sending device;

sending a remote CTA request frame to the sending device in order for the sending device to request the CTA from a coordinator within the wireless network for data transmission; and

receiving a data frame transmitted by the sending device during channel time allocated by the coordinator.

12. A computer-readable recording storage having a computer readable program recorded therein for causing a computer to implement a method for communication in a coordinator-based wireless network, the method comprising:

sending a frame indicating data transmission containing information needed for channel time allocation (CTA) to a target device, in order for the target device to generate a remote CTA request frame;

receiving the remote CTA request frame from the target device;

requesting CTA from a coordinator within the wireless network for data reception, according to the remote CTA request; and

sending a data frame to the target device during channel time assigned by the coordinator.

13. A computer-readable recording storage having a computer readable program recorded therein for causing a computer to implement a method for communication between first and second coordinator-based wireless networks connected through a backbone network, the method comprising:

sending a frame indicating data transmission from a sending device in the first coordinator-based wireless network to a repeater connecting the first coordinator-based wireless network with the backbone network in order for a target device within the second coordinator-based wireless network to request remote channel time allocation (CTA); and

sending a frame to be destined for the target device from the sending device to the repeater after sending the frame indicating data transmission.

14. A computer-readable recording storage having a computer readable program recorded therein for causing a computer to implement a method for communication between first and second coordinator-based wireless networks connected through a backbone network, the method comprising:

receiving a frame indicating data transmission containing information needed for remote channel time allocation (CTA) from a repeater connecting the second coordinator-based wireless network with the backbone network;

sending a remote CTA frame in order for the repeater to request CTA from the coordinator within the second coordinator-based wireless network; and
