Method and system for suppressing early media in a communications network
First Claim
Patent Images
1. A method for managing call establishment in a communications system, the method comprising:
- receiving a session progress indication associated with a call;
determining whether the session progress indication is to be suppressed during establishment of the call; and
responsive to whether the session progress indication is to be suppressed, suppressing the session progress indication.

Abstract
An approach is provided for supporting telephony services over a data communication network. A network server receives multiple early media streams associated with a communication session between an originating network element and one or more terminating network elements. The network server selectively suppresses the early media streams, such that the originating network element receives a single signaling message indicating status information of the communication session (or call). The present invention has particular applicability to SIP (Session Initiation Protocol) IP (Internet Protocol) telephony services.

20. A method for managing a call within a communications system, the method comprising:
-
receiving a request from a first entity for a call to be established with a second entity; determining whether suppression of early media is needed for the call; dispatching a message related to establishing the call; receiving a response to the message comprising early media provisions; modifying the response to remove the early media provisions; and sending the modified response to the first entity. - View Dependent Claims (21)

22. A network server for supporting call establishment in a communications system, the network server comprising:
-
means for receiving a session progress indication; means for determining a call to which the session progress indication pertains; means for determining whether the session progress indication is to be suppressed during establishment of the call; and means for suppressing the session progress indication responsive to whether the session progress indication is to be suppressed.

23. A method of supporting telephony services over a data communication network, the method comprising:
-
receiving a plurality of media streams associated with a communication session between an originating network element and a plurality of terminating network elements, each of the media streams being received from a respective one of the terminating network elements and specifying a communication parameter of the communication session; converting the media streams to a single signaling stream; and forwarding the signaling stream to the originating network element. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30)

31. A computer-readable medium carrying one or more sequences of one or more instructions for supporting telephony services over a data communication network, the one or more sequences of one or more instructions including instructions which, when executed by one or more processors, cause the one or more processors to perform the steps of:
-
receiving a plurality of media streams associated with a communication session between an originating network element and a plurality of terminating network elements, each of the media streams being received from a respective one of the terminating network elements and specifying a communication parameter of the communication session; converting the media streams to a single signaling stream; and forwarding the signaling stream to the originating network element. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38)

39. An apparatus of supporting telephony services over a data communication network, the apparatus comprising:
-
a communication interface configured to receive a plurality of media streams associated with a communication session between an originating network element and a plurality of terminating network elements, each of the media streams being received from a respective one of the terminating network elements and specifying a communication parameter of the communication session; and a processor coupled to the communication interface, and configured to convert the media streams to a single signaling stream, wherein the signaling stream is forwarded to the originating network element. - View Dependent Claims (40, 41, 42, 43, 44, 45, 46)
