Abstract: Client devices/applications associated with a subscriber of an enhanced communication system are enabled to generate communication records identifying individual communication sessions along with tie-breaker values such that the records can be evaluated following a trigger event and duplicate records for the same subscriber can be removed in order to provide accurate information to the subscriber when the event is over.

Abstract: Established multimodal conversations are enabled to be parked within an enhanced communication system such that a subscriber of the system can be notified through a variety of means and enabled to retrieve selected or all modalities for continuing the conversation. Different modalities may be parked together or separately. While waiting for the subscriber to retrieve the conversation, a participant may receive audio, video, presentation, or other forms of content as playback.

Abstract: The present invention incorporates an intermediary proxy rules device that has access to information regarding network address and port bindings or network address and port translations. This intermediary function communicates translated address information to other devices on the network, such as the policy and charging rule function and policy and charging enforcement function. The full communication and coordination of this information coordinates correct translation address information and other necessary information to these PCRF and PCEF devices, which eliminates many of the problems associated with the session set-up and maintenance with other networks.

Abstract: The present invention provides a technique for providing a forced hold service such as is used for an emergency services call, which is supported at least in part over a packet network. The forced hold service acts to effectively hold a connection for the call with a called party, even when the caller takes an action that would normally end a call, such as going on hook, pressing end, or the like. When the caller takes an action that would normally end the call, the forced hold service allows the caller to automatically reconnect to the emergency services provider over the held connection upon going offhook, pressing send, or the like. Alternatively, the emergency services provider can effectively re-engage the call wherein the caller is reconnected over the held connection upon going offhook, pressing send, or the like.

Abstract: If a communication client disconnects from a call, an interworking service node may receive from the communication client a disconnect message indicative of an attempt to disconnect the call and send a forced hold message to place the call on forced hold in response to receiving the disconnect message. A portion of the call extending toward a public service access point and through the PSTN is placed on hold. When an operator wants to reestablish the call to the communication client, the interworking service node will receive over the PSTN a reconnect request message to reestablish the call with the communication client. The reconnect request message may be an integrated services user part message. In response to the reconnect message, the interworking service node will generate and send a session initiation message, which is configured to reestablish the call toward the communication client.

Abstract: Disclosed is one embodiment of a system and method for negotiating a compression technique while signaling is occurring in a communications network, the method comprising sending a message with a compression negotiation indicator, receiving a response to the message, determining if the response contains an error code in response to the compression header, if the message contains an error code, then continuing signaling without using compression techniques. On the other hand, if the message does not contain an error code, then the method negotiates a compression technique and may continue signaling with the negotiated compression technique.
