Abstract

This invention relates to communication systems and QSIG communication methods. According to a first aspect, a communication system includes a control component; and a data network configured to communicate packets of information intermediate an originating location and a terminating location, the originating location being configured to receive a QSIG communication including a content portion and a signaling portion, wherein the data network is configured to communicate the signaling portion to the control component and the control component is configured to establish a connection within the data network intermediate the originating location and the terminating location responsive to the signaling portion, and wherein the data network is further configured to communicate the content portion of the communication within a plurality of packets intermediate the originating location and the terminating location using the connection.

Claims

1-28. -28. (canceled)

29. A method comprising:

partitioning inter-Private Branch Exchange (PBX) communications from existing PBX communications, where an inter-PBX communication is received from a device not supported by a PBX;

receiving a partitioned inter-PBX communication, the partitioned inter-PBX communication including a signal packet including QSIG signaling information; and

establishing a bearer channel connection between a first network access device and a second network access device using the QSIG signaling information.

30. The method of claim 29 where the received signal packet is transmitted from a first network device to a control component.

31. The method of claim 30 where the control component establishes the bearer channel connection between the first network access device and the second network access device.

32. The method of claim 29 further comprising:

transmitting content packets between the first network access device and the second network access device.

33. The method of claim 29 further comprising:

mapping the received QSIG signaling information to another protocol prior to establishing the bearer channel.

34. A method comprising:

partitioning inter-Private Branch Exchange (PBX) communications from existing PBX communications, where an inter-PBX communication is received from a device not supported by a PBX;

receiving a partitioned inter-PBX communication, the partitioned inter-PBX communication including a QSIG communication including a content portion and a signaling portion;

encapsulating the content portion and the signaling portion of the partitioned inter-PBX communication to provide a plurality of respective content packets and signaling packets; and

transmitting the signaling packets to a control component for use in establishing a connection between a first network access device and a second network access device.

35. The method of claim 34 where the network access device receives the partitioned inter-PBX QSIG communication from a PBX switch.

36. The method of claim 34 further comprising:

establishing a bearer channel connection between the first network access device and the second network access device.

37. The method of claim 34 further comprising:

transmitting the content packets from the first network access device to the second network access device.

38. The method of claim 34 where the second network access device is a non-QSIG device.

39. A system comprising:

a Private Branch Exchange (PBX) switch configured to;

partition inter-PBX communications from existing PBX communications, where an inter-PBX communication is received from a device not supported by the PBX switch; and

a network access device configured to;

receive a partitioned inter-PBX communication that includes a QSIG signal that contains a signal portion and a content portion;

encapsulate the received signal portion into signal packets and the received content portion into content packets; and

transmit the signal packets to establish a communication channel to a second network access device.

40. The system of claim 39 where when transmitting the signal packets, the network access device is configured to:

transmit the signal packets to a control component via a data network.

41. The system of claim 40 where the communication channel is established through the data network.

42. The system of claim 39 where the network access device is further configured to:

transmit the content packets to the second network access device.

43. The system of claim 39 where the received signal portion and the received content portion are continuous signals.

44. The system of claim 39 where the network access device receives the partitioned inter-PBX QSIG signal from the PBX switch.

45. A system comprising:

a Private Branch Exchange (PBX) switch configured to;

partition inter-PBX communications from existing PBX communications, where an inter-PBX communication is received from a device not supported by the PBX switch; and

a control component configured to;

receive a partitioned inter-PBX communication that includes a signal packet that includes QSIG information; and

establish a bearer communication channel between a first network access device and a second network access device using the received QSIG information.

46. The system of claim 45 where the control component receives the signal packet from the first network access device.

47. The system of claim 46 where the control component is further configured to:

map the received signal packet to another protocol for transmission to the second network access device.

48. The system of claim 45 where the control component is further configured to:

return the bearer channel to an idle state after transmission of content packets from the first network access device to the second network access device.
