Abstract

A system and method for reducing latency includes receiving at a gateway time division multiplexed data from multiple sender devices, the time division multiplexed data including payloads. The method also includes a generated packet that includes the payloads from the received time division multiplexed data from the multiple sender devices. The method also includes indicating in the generated packet a destination indication associated with at least some of the payloads of the received time division multiplexed data and forwarding the generated packet to a media server.

Claims

1. A method comprising:

receiving at a gateway time division multiplexed data from multiple sender devices or TDM channels, the time division multiplexed data including payloads;

generating a generated packet that includes the payloads from the received time division multiplexed data from the multiple sender devices;

indicating in the generated packet a destination indication associated with at least some of the payloads of the received time division multiplexed data; and

forwarding the generated packet toward a device on an Internet Protocol (IP) based network.

2. The method of claim 1 wherein the device on an Internet Protocol (IP) based network is a media server.

3. The method of claim 1 wherein the destination indication indicates an associated data channel.

4. The method of claim 1 wherein the destination indication indicates an associated port.

5. The method of claim 1 wherein the payloads have a fixed length.

6. The method of claim 1 wherein the payloads include voice frames.

7. The method of claim 1 wherein the payloads only include voice frames.

8. The method of claim 1 wherein the payloads include silence indication (SID) frames.

9. The method of claim 1 wherein the payloads only include silence indication (SID) frames.

10. The method of claim 1 further comprising limiting the length of the formed packet based on an IP network protocol.

11. The method of claim 1 further comprising forwarding a tone packet separately from the generated packet.

12. The method of claim 1 wherein forwarding the generated packet to a media server reduces latency in receiving the packet compared to receiving the plurality of packets.

13. The method of claim 1 wherein the time division multiplexed data is from a plurality of systems.

14. The method of claim 1 wherein the generated packet includes:

an IP header,

a UDP header,

an RTP header, and

a payload comprising alternating sequences of a destination indication and an associated payload of the received time division multiplexed data.

15. A device configured to:

receive time division multiplexed data from multiple sender devices or TDM channels on the TDM based network, the time division multiplexed data including payloads;

generate a generated packet that includes the payloads from the received time division multiplexed data from the multiple sender devices;

indicate in the generated packet a destination indication associated with at least some of the payloads of the received time division multiplexed data; and

forward the generated packet toward a device on the IP based network.

16. The device of claim 15 wherein the payloads have a fixed length.

17. The device of claim 15 wherein the payloads include voice frames.

18. The device of claim 15 wherein the payloads include silence indication frames.

19. The device of claim 15 further configured to forward a tone packet separately from the generated packet.

20. A computer program product, tangibly embodied in an information carrier, for executing instructions on a processor, the computer program product being operable to cause a machine to:

receive time division multiplexed data from multiple sender devices or TDM channels on a TDM based network, the time division multiplexed data including payloads;

generate a generated packet that includes the payloads from the received time division multiplexed data from the multiple sender devices;

indicate in the generated packet a destination indication associated with at least some of the payloads of the received time division multiplexed data; and

forward the generated packet toward a device on an IP based network.

21. The computer program product of claim 20 further comprising instructions to limit the length of the formed packet based on a network protocol.

22. The computer program product of claim 20 further comprising instructions to forward a tone packet separately from the generated packet.

23. A system comprising:

an input;

a gateway; and

an output, wherein;

the input provides a communication path between a TDM based network and the gateway;

the output provides a communication path between the gateway and an IP based network; and

the gateway is configured to;

receive time division multiplexed data from the input, the time division multiplexed data including payloads;

generate a generated packet that includes the payloads from the received time division multiplexed data;

indicate in the generated packet a destination indication associated with at least some of the payloads of the received time division multiplexed data; and

forward the generated packet to a device on an IP based network.

24. The system of claim 23 wherein the gateway is further configured to forward a tone packet separately from the generated packer.

25. A method comprising:

receiving a packet from a device on an Internet Protocol (IP) based network, the packet including a payload comprising data from multiple sender devices on a TDM based network;

generating a generated packet that includes a payload comprising a portion of the payload from the received packet; and

forwarding the generated packet to a device on the TDM based network.

26. The method of claim 25 wherein the payload includes at least one of voice frames and silence indication frames.

27. The method of claim 25 further comprising forwarding a tone packet separately from the generated packet.

28. A media gateway configured to:

receive a packet from a device on an Internet Protocol (IP) based network, the packet including a payload comprising data from multiple sender devices on a TDM based network;

generate a generated packet that includes a portion of the payload from the received packet; and

forward the generated packet to a device on the TDM based network.

29. The device of claim 28 wherein the payload includes voice frames.

30. The device of claim 28 wherein the payload includes silence indication frames.

31. The device of claim 28 further configured to forward a tone packet separately from the generated packet.

32. A computer program product, tangibly embodied in an information carrier, for executing instructions on a processor, the computer program product being operable to cause a machine to:

receive a packet from a device on an Internet Protocol (IP) based network, the packet including a payload comprising data from multiple sender devices on a TDM based network;

generate a generated packet that includes a portion of the payload from the received packet; and

forward the generated packet to a device on the TDM based network.

33. The method of claim 32 wherein the computer program product further comprises instructions to forward a tone packet separately from the generated packet.
