Abstract

Various embodiments provide methods and systems operable to provide access to real time control protocol (RTCP) information for improved media quality control. An example embodiment includes a message processor to receive a message, the message including information indicative of an RTP port identifier, and to add to the received message information indicative of an auxiliary RTCP port identifier; and a message communication component to communicate the information indicative of an auxiliary RTCP port identifier to a node.

Claims

1-28. -28. (canceled)

29. A computer-implemented method comprising:

receiving a message, the message including information indicative of a Real-time Transport Protocol (RTP) port identifier; and

adding to the received message information indicative of an auxiliary Real-time Transport Control Protocol (RTCP) port identifier, wherein the auxiliary RTCP port identifier is used to transfer at least one of call information and media status information to a node.

30. The method of claim 29, wherein an auxiliary RTCP port identified in the information indicative of an auxiliary RTCP port identifier is used to transfer at least one of the call information and the media status information to the node.

31. The method of claim 29, further comprising communicating the information indicative of an auxiliary RTCP port identifier to an originating gateway node.

32. The method of claim 29, further comprising communicating the information indicative of an auxiliary RTCP port identifier to a target gateway node.

33. The method of claim 29, further comprising communicating the information indicative of an auxiliary RTCP port identifier to a third party node.

34. The method of claim 29, wherein the information indicative of an auxiliary RTCP port identifier includes information indicative of a node address.

35. The method of claim 29, wherein the information indicative of an auxiliary RTCP port identifier includes information indicative of a plurality of auxiliary RTCP port identifiers.

36. A system comprising:

a machine including a memory and at least one processor; and

a message processor, executable by the machine, configured to;

receive a message, the message including information indicative of a Real-time Transport Protocol (RTP) port identifier; and

add to the received message information indicative of an auxiliary Real-time Transport Control Protocol (RTCP) port identifier, wherein the auxiliary RTCP port identifier is used to transfer at least one of call information and media status information to a node.

37. The system of claim 36, wherein an auxiliary RTCP port identified in the information indicative of an auxiliary RTCP port identifier is used to transfer at least one of the call information and the media status information to the node.

38. The system of claim 36, further comprising a message communication component configured to communicate the information indicative of an auxiliary RTCP port identifier to an originating gateway node.

39. The system of claim 36, further comprising a message communication component configured to communicate the information indicative of an auxiliary RTCP port identifier to a target gateway node.

40. The system of claim 36, further comprising a message communication component configured to communicate the information indicative of an auxiliary RTCP port identifier to a third party node.

41. The system of claim 36, wherein the information indicative of an auxiliary RTCP port identifier includes information indicative of a node address.

42. The system of claim 36, wherein the information indicative of an auxiliary RTCP port identifier includes information indicative of a plurality of auxiliary RTCP port identifiers.

43. A non-transitory machine-readable storage medium comprising instructions that, when executed by one or more processors of a machine, cause the machine to perform operations comprising:

receiving a message, the message including information indicative of a Real-time Transport Protocol (RTP) port identifier; and

adding to the received message information indicative of an auxiliary Real-time Transport Control Protocol (RTCP) port identifier, wherein the auxiliary RTCP port identifier is used to transfer at least one of call information and media status information to a node.

44. The storage medium of claim 43, wherein an auxiliary RTCP port identified in the information indicative of an auxiliary RTCP port identifier is used to transfer at least one of the call information and the media status information to the node.

45. The storage medium of claim 43, wherein the operations further comprise communicating the information indicative of an auxiliary RTCP port identifier to an originating gateway node.

46. The storage medium of claim 43, wherein the operations further comprise communicating the information indicative of an auxiliary RTCP port identifier to a target gateway node.

47. The storage medium of claim 43, wherein the operations further comprise communicating the information indicative of an auxiliary RTCP port identifier to a third party node.

48. The storage medium of claim 43, wherein the information indicative of an auxiliary RTCP port identifier includes information indicative of a node address.
