Abstract

Aspects of a method and system for servicing a plurality of users via a plurality of femtocells are provided. In this regard, a cellular enabled communication device may receive portions of a datastream from a plurality of femtocells, reconstruct the datastream from the received portions of the datastream, and process the reconstructed datastream for presentation to a user of the cellular enabled communication device. The received portions may be buffered in the cellular enabled communication device. The portions of the datastream may be associated with a plurality of CDMA channel access codes. The portions of the datastream may be received via a plurality of cellular frequencies. The portions of the datastream may be received during a plurality of TDMA timeslots. Portions of the datastream may be received from a cellular base station. Portions of the datastream may be received from a WiMAX base station.

Claims

1. A method for communication, the method comprising:

receiving, in a cellular enabled communication device, synchronization information to synchronize said cellular enabled communication device with a plurality of femtocells;

receiving, in the cellular enabled communication device, portions of a datastream from the plurality of femtocells;

reconstructing said datastream from said received portions of said datastream based on said synchronization information, wherein said reconstructing of said datastream includes reordering at least one of said received portions that is temporally out of order with respect to at least one other of said received portions; and

processing said reconstructed datastream for presentation by said cellular enabled communication device.

2. The method according to claim 1, wherein receiving said synchronization information comprises receiving signals from a global navigation satellite system, said signals being utilized to synchronize said cellular enabled communication device with said plurality of femtocells.

3. The method according to claim 1, further comprising buffering said received portions of said datastream.

4. The method according to claim 1, receiving wherein said received portions of said datastream are associated with multiple Code Division Multiple Access (CDMA) channel access codes.

5. The method according to claim 1, wherein said received portions of said datastream are received during multiple Time Division Multiple Access (TDMA) timeslots.

6. The method according to claim 1, wherein said received portions of said datastream are received on multiple cellular frequencies.

7. The method according to claim 1, wherein said received portions of said datastream are received from a cellular base station.

8. The method according to claim 1, wherein said received portions of said datastream are received from a Worldwide Interoperability for Microwave Access (WiMAX) base station.

9. The method according to claim 1, wherein said reordering is based on timestamps inserted into said datastream by said plurality of femtocells.

10. The method according to claim 1, wherein said reordering is based on frame sequence numbers inserted into said datastream by said plurality of femtocells.

11. The method according to claim 1, further comprising:

receiving, by said cellular enabled communication device, a coordinated management plan from one or more femtocells of said plurality of femtocells, wherein said portions of said datastream are received from said plurality of femtocells based on said coordinated management plan.

12. A system for communication, the system comprising:

one or more circuits for use in a cellular enabled communication device, said one or more circuits being configured to;

receive synchronization information to synchronize said cellular enabled communication device with a plurality of femtocells;

receive portions of a datastream from the plurality of femtocells;

reconstruct said datastream from said received portions of said datastream based on said synchronization information, wherein said reconstruction includes reordering at least one of said received portions that is temporally out of order with respect to at least one other of said received portions; and

process said reconstructed datastream for presentation to a user of said cellular enabled communication device.

13. The system according to claim 12, wherein said synchronization information comprises signals from a global navigation satellite system, said signals being utilized to synchronize said cellular enabled communication device with said plurality of femtocells.

14. The system according to claim 12, wherein said one or more circuits are further configured to buffer said received portions of said datastream.

15. The system according to claim 12, wherein said one or more circuits are configured to receive portions of said datastream that are associated with multiple Code Division Multiple Access (CDMA) channel access codes.

16. The system according to claim 12, wherein said one or more circuits are configured to receive portions of said datastream during multiple Time Division Multiple Access (TDMA) timeslots.

17. The system according to claim 12, wherein said one or more circuits are configured to receive portions of said datastream on multiple cellular frequencies.

18. The system according to claim 12, wherein said one or more circuits are configured to receive portions of said datastream from a cellular base station.

19. The system according to claim 12, wherein said one or more circuits are configured to receive portions of said datastream from a Worldwide Interoperability for Microwave Access (WiMAX) base station.

20. The system according to claim 12, wherein said one or more circuits are configured to receive a coordinated management plan from one or more femtocells of said plurality of femtocells, wherein said portions of said datastream are received from said plurality of femtocells based on said coordinated management plan.
