Abstract

The present invention provides a method of wireless telecommunication is provided. The method includes accessing a plurality of first data packets having a first size, accessing at least one second data packet having a second size, the second size being larger than the first size, forming a plurality of third data packets comprising portions of the at least one second data packet based upon the first and second sizes, and selecting at least one of the plurality of first data packets based upon the plurality of third data packets.

Claims (26)

1. A method of splitting packets for use in wireless communication, comprising:

accessing, at a wireless transmission unit, a plurality of first data packets having a first size;

accessing, at the wireless transmission unit, at least one second data packet having a second size, the second size being larger than the first size;

forming, at the wireless transmission unit, a plurality of third data packets comprising portions of the at least one second data packet based upon the first and second sizes, wherein number of third packets is given by a ratio of the second size to the first size;

dropping at least one of the plurality of first data packets, wherein number of dropped first data packets being one less that the number of third data packets; and

transmitting, from the wireless transmission unit, the plurality of third data packets in time slots allocated to said at least one second data packet and said at least one dropped first data packet.

2. The method of claim 1 , wherein accessing the plurality of first data packets comprises accessing a plurality of compressed data packets.

3. The method of claim 2 , wherein accessing the plurality of first data packets comprises accessing a plurality of first data packets including a speech frame and a compressed packet header.

4. The method of claim 1 , wherein accessing the plurality of first data packets comprises accessing a plurality of first data packets associated with consecutive time slots.

5. The method of claim 1 , wherein accessing said at least one second data packet comprises accessing at least one of an uncompressed data packet and a partially compressed data packet.

6. The method of claim 5 , wherein accessing at least one of the uncompressed data packet and the partially compressed data packet comprises accessing at least one second data packet including a speech frame and at least one of an uncompressed packet header and a partially compressed packet header.

7. The method of claim 1 , wherein forming the plurality of third data packets comprises determining header information based upon header information associated with one of the first data packets that is scheduled to be transmitted before the second data packet.

8. The method of claim 1 , wherein forming the plurality of third data packets comprises determining header information based upon predicted header information associated with one of the first data packets that is scheduled to be transmitted after the second data packet.

9. The method of claim 8 , wherein forming the plurality of third data packets comprises forming a virtual data packet based on the predicted header information.

10. The method of claim 1 , wherein selecting said at least one of the plurality of first data packets comprises selecting a number of first data packets that is equal to one less than the number of third data packets.

11. The method of claim 1 , comprising transmitting the plurality of third data packets in consecutive time slots.

12. The method of claim 1 , wherein accessing said at least one second data packet comprises accessing a plurality of second data packets.

13. A method of splitting packets for use in wireless communication, comprising:

receiving, at a reception unit and from a transmission unit, a plurality of first data packets having a first size, wherein receiving the plurality of first data packets comprises receiving a plurality of data packets comprising information indicative of an uncompressed data packet; and

forming, at the reception unit, at least one second data packet having a second size based on the plurality of first data packets, the second size being larger than the first size, and wherein at least one of the plurality of first data packets is transmitted in at least one time slot allocated to at least one third data packet that, wherein was dropped by the transmission unit to allow the plurality of first data packets to be transmitted.

14. The method of claim 13 , wherein forming the at least one second data packet comprises forming a reconstructed data packet based on the information indicative of the uncompressed data packet.

15. The method of claim 14 , wherein forming the reconstructed data packet based on the information indicative of the uncompressed data packet comprises forming a reconstructed data packet that comprises the same information as the uncompressed data packet.

16. The method of claim 13 , wherein receiving the plurality of first data packets comprises receiving a plurality of first data packets comprising information indicative of a speech frame and a packet header.

17. The method of claim 16 , wherein receiving the plurality of first data packets comprising information indicative of the packet header comprises receiving the plurality of first data packets comprising information indicative of a predicted packet header.

18. The method of claim 13 , comprising receiving at least one third data packet.

19. The method of claim 18 , wherein receiving the at least one third data packet comprises receiving at least one compressed data packet.
