Abstract

Data transmission apparatus for transmitting the data of a data frame as a plurality of packets, comprising: segmentation apparatus capable of identifying delay-critical data within the data frame, and forming a plurality of packets comprising data of the data frame, wherein the identified data is formed in to one or more packets capable of being decoded independently of the other packets; and a transmitter for transmitting the packets.

Claims

1. Data transmission apparatus for transmitting the data of a data frame as a plurality of packets, comprising:

segmentation apparatus capable of identifying delay-critical data within the data frame, and forming a plurality of packets comprising data of the data frame, wherein the identified data is formed in to one or more packets capable of being decoded independently of the other packets; and

a transmitter for transmitting the packets.

2. Data transmission apparatus according to claim 1, wherein the transmitter is configured to transmit the one or more packets capable of being decoded independently of the other packets before transmitting the other packets.

3. Data transmission apparatus according to claim 1 or claim 2, wherein the other packets do not comprise identified data.

4. Data transmission apparatus according to any preceding claim, wherein the one or more packets capable of being decoded independently of the other packets are transmitted directly to the receiver in immediate succession.

5. Data transmission apparatus according to any preceding claim, wherein the other packets are transmitted such that they may be interspersed with other data.

6. Data transmission apparatus according to any preceding claim, wherein the delay-critical data is signal quality information.

7. Data transmission apparatus according to any preceding claim, wherein the delay-critical data is error information.

8. Data transmission apparatus according to any preceding claims wherein the delay-critical data is power control information.

9. Data transmission apparatus according to any preceding claim, wherein the data frame is transmitted over a telecommunications network interface.

10. Data transmission apparatus according to claim 9, wherein the data frame is transmitted from a base station.

11. Data transmission apparatus according to claim 9 or claim 10, wherein the data frame is transmitted to a radio network controller.

12. Data transmission apparatus according to any of claims 9 to 11, wherein the data frame is transmitted from a mobile telephone.

13. Data transmission apparatus according to claim 9, wherein the data frame is transmitted to a base station.

14. Data transmission apparatus according to claim 9 or claim 10, wherein the data frame is transmitted from a radio network controller.

15. Data transmission apparatus according to any preceding claim, wherein the data frame comprises voice information.

16. Data transmission apparatus according to any preceding claim, substantially herein as described with reference to the accompanying drawings.

17. A method of transmitting the data of a data frame as a plurality of packets, comprising the steps of:

identified delay-critical data within the data frame;

forming a plurality of packets comprising data of the data frame, such that the identified data is formed in to one or more packets capable of being decoded independently of the other packets; and

transmitting the packets.

18. A method according to claim 17, wherein the one or more packets capable of being decoded independently of the other packets are transmitted before the other packets.

19. A method according to claim 17 or claim 18, wherein the other packets do not comprise identified data.

20. A method according to any of claims 17 to 19, wherein the one or more packets capable of being decoded independently of the other packets are transmitted directly to the receiver in immediate succession.

21. A method according to any of claims 17 to 20, wherein the other packets are transmitted interspersed with other data.

22. A method substantially herein as described with reference to the accompanying drawings.
