Abstract

An apparatus for communicating between a mobile device, and a plurality of transceivers. The apparatus includes a first transceiver which transmits to the mobile device on any one of a plurality of channels. The apparatus further includes a second transceiver which transmits to the mobile device on any one of the plurality of channels.

Claims

1. A method for communicating between a mobile device, first and second transceivers wherein the second transceiver is positioned in an area covered by the first transceiver, wherein a first signal received by the mobile device from the first transceiver has lower energy than a second signal received by the mobile device from the second transceiver, the method comprising:

transmitting from the first transceiver to the mobile device on any one of a plurality of channels; and

transmitting from the second transceiver to the mobile device on any one of the plurality of channels, the plurality of channels including the one channel on which the first transceiver is transmitting.

2. The method of claim 1, further comprising:

transmitting from the mobile device to the first transceiver on the one channel on which the first transceiver is transmitting to the mobile device; and

transmitting from the mobile device to the second transceiver on any of the plurality of channels other than the one channel or on a channel separate from the plurality of channels.

3. The method of claim 1, wherein the first transceiver is a satellite transceiver.

4. The method of claim 1, wherein the second transceiver is a base station.

5. The method of claim 1, wherein any one of the plurality of channels other than the one channel is an Auxiliary Terrestrial Component (ATC) channel.

6. The method of claim 1, wherein the one channel used in a transmission from the first transceiver or from the second transceiver is configured to be both a Mobile Satellite System (MSS) channel and an Auxiliary Terrestrial Component (ATC) channel.

7. The method of claim 1, wherein each of the plurality of channels is configured to be both a satellite channel for communications from a satellite to the mobile device and a terrestrial channel for communication from a base station to the mobile device.

8. The method of claim 7, further comprising:

transmitting from the mobile device to the satellite on the satellite channel, and transmitting from the mobile device to the base station on a channel separate from the plurality of channels.

9. The method of claim 8, wherein the channel separate from the plurality of channels is one channel in a plurality of terrestrial out-of-band (OOB) channels.

10. The method of claim 9, further comprising pairing each of the plurality of terrestrial out-of-band channels with a respective terrestrial channel in the plurality of channels.

11. A method for communicating between a mobile device and first and second transceivers, wherein the second transceiver is positioned in an area covered by the first transceiver, wherein a first signal received by the mobile device from the first transceiver has lower energy that the a second signal received by the mobile device from the second transceiver, the method comprising:

transmitting from the mobile device to the first transceiver on any one of a plurality of channels; and

transmitting from the mobile device to a second transceiver on any of the plurality of channels other than the one channel or on a channel separate from the plurality of channels.

12. The method of claim 11, wherein the first transceiver is a satellite transceiver.

13. The method of claim 11, wherein the second transceiver is a base station.

14. The method of claim 11, wherein any one of the plurality of channels other than the one channel is an Auxiliary Terrestrial Component (ATC) channel.

15. The method of claim 11, wherein transmitting from the mobile device to the first transceiver on any one of a plurality of channels comprises transmitting from the mobile device to a satellite on a satellite channel in the plurality of channels.

16. The method of claim 11, wherein transmitting from the mobile device to the second transceiver comprises transmitting from the mobile device to a base station on a channel separate from the plurality of channels.

17. The method of claim 16, wherein the channel separate from the plurality of channels is one channel in a plurality of terrestrial out-of-hand (OOB) channels.

18. The method of claim 17, wherein the terrestrial out-of-band channels are Auxiliary Terrestrial Component (ATC) channels.

19. The method of claim 17, further comprising pairing each of the plurality of terrestrial out-of-band (OOB) channels with a respective terrestrial channel in the plurality of channels.

20. An apparatus for communicating with a mobile device, the apparatus comprising:

a first transceiver which transmits to the mobile device on any one of a plurality of channels; and

a second transceiver which transmits to the mobile device on any one of the plurality of channels, the plurality of channels including the one channel on which the first transceiver is transmitting, wherein the second transceiver is positioned in an area covered by the first transceiver, and wherein a first signal received by the mobile device from the first transceiver has lower energy than a second signal received by the mobile device from the second transceiver.

21. The apparatus of claim 20, further comprising the mobile device, wherein the mobile device transmits to the first transceiver on the one channel on which the first transceiver is transmitting to the mobile device, and transmits to the second transceiver on any of the plurality of channels other than the one channel or on a channel separate from the plurality of channels.

22. The apparatus of claim 20, wherein the first transceiver is a satellite transceiver.

23. The apparatus of claim 20, wherein the second transceiver is a base station.

24. The apparatus of claim 20, wherein any one of the plurality of channels other than the one channel is an Auxiliary Terrestrial Component (ATC) channel.

25. The apparatus of claim 20, wherein the one channel used in a transmission from the first transceiver or from the second transceiver is configured to be both a Mobile Satellite System (MSS) channel and an Auxiliary Terrestrial Component (ATC) channel.

26. The apparatus of claim 20, wherein each of the plurality of channels is configured to be both a satellite channel for communications from a satellite to the mobile device and a terrestrial channel for communication from a base station to the mobile device.

27. The apparatus of claim 26, wherein the mobile device is configured to transmit to the satellite on the satellite channel, and to transmit to the base station on a channel separate from the plurality of channels.

28. The apparatus of claim 27, wherein the channel separate from the plurality of channels is one channel in a plurality of terrestrial out-of-band (OOB) channels.

29. The apparatus of claim 28, wherein each of the plurality of terrestrial out-of-band (OOB) channels is paired with a respective terrestrial channel in the plurality of channels.
