Tue Jul 27 18:09:57 EDT 2004
The present invention enables a party which is placed on hold in a first communication session to enter a second communication session and continue to monitor the status of the first communication. For example, in a broadband communication system telephone call or multimedia call, two parties may be in an active communication session with one another and a first of the two parties to the call may receive another incoming call. The first party then places the second party on hold. At this time the second party may wish to place the communication session with the first party on hold to initiate another communication session with a third party. However, the second party would also like to know when the first party takes the communication session off hold so that they can resume their communication. As a result, the second party places the communication on monitor hold. While the communication is on monitor hold, the second party is able to monitor the on hold communication session to recognize when the first party returns. For example, the monitored call on hold may be maintained at a reduced volume or a video display of the video in a multimedia communication session may be displayed in a reduced window size on a display. Further, the present invention provides prompts to various parties of a communication session when one or more parties to the communication session are placed on hold or taken off hold. For example, the system may generate a prompt to one or more parties when a communication session is placed on hold or monitor hold, or when a communication session on hold or monitor hold is taken off hold.

Low-Latency Audio Interface For Packet Telephony,
Tue Apr 29 18:08:40 EDT 2003
In a method for reducing latency in packet telephony caused by buffering at the conversion stage between analog audio signals and digital audio data, analog audio is sampled at a rate far greater than necessary for telephony. The increased sampling rate allows the audio data to pass much more rapidly through the data conversion buffer. After passing through the buffer, the data is downsampled to a rate normally used for telephony. To handle audio data for speaker output, the data is upsampled to a rate far in excess of the rate necessary for processing telephony-grade voice signals. The increased sampling rate allows the audio data to pass much more rapidly through the data conversion buffer. After passing through the buffer, the data is converted into an analog audio signal for sending to the speaker. In this way, latency due to the buffering that accompanies the process of converting audio signals to digital data, or vice versa, is minimized.

Apparatus and method for selecting communication modes,
Tue Mar 12 18:07:22 EST 2002
The present invention provides an apparatus and method that allows the communication mode for communicating between two user devices to be selected based on the abilities of the user devices and/or the preferences of the users. Using the present invention, when an operator of a user device enters the destination address for another user device with which communication is sought, a Client Routing Assessment Profile Services (CRAPS) processor receives the signals from the source user device. The signals include information of the identity of the source user device and the destination user device. The CRAPS processor retrieves profile information from a database corresponding to the identity of the source user device and/or the destination user device. Based on the profile information retrieved, the CRAPS processor sends boot signals to the user devices involved in the communication instructing them to change to the appropriate communication mode. Once the user devices are operating in the same mode, the CRAPS processor enables the communication between the user devices until an end condition occurs.
Method and system for transferring digital data calls between different destinations,
Tue Nov 20 18:07:17 EST 2001
A method and a system for routing data calls in which an incoming data call having a destination number is received.

The incoming data call is associated with an automatic number identification and the input port is associated with an input port identification. The automatic number identification is stored in a database in association with the input port identification. A transfer message for the data call is received from the first destination. The transfer message contains information relating to an address for a second destination. The information relating to the address for the second destination is stored in the database in association with the automatic number identification and input port identification for the data call. The data call is disconnected from the first destination, and the data call is routed to the second destination over the circuit-switched telecommunications network.
Methods and apparatus for providing improved quality of packet transmission in applications such as internet telephony,
Tue Nov 20 18:07:16 EST 2001
A digital data packet transmission process and system provides; more efficient and higher quality of service in applications such as Internet telephony. In one aspect of this approach, transmission control protocol (TCP) is used to send data from a first user or client over standard telephone lines to a local Internet service provider (ISP). At the ISP, the data packets are converted from TCP to user datagram protocol (UDP). The UDP packets are then transmitted, typically over a higher bandwidth link to another local ISP serving the recipient. The UDP packets are translated back to TCP packets and routed to the receiver. Because many existing systems currently employ UDP packets, the present approach is largely backwards compatible should a recipient be hooked up to an ISP that does not employ a TCP/UDP converter. A bidirectional TCP/UDP converter is preferable for two way communication such as Internet telephony.
Low-latency buffering for packet telephony,
Tue Oct 09 18:07:14 EDT 2001
In a method for reducing latency in packet telephony caused by anti-jitter buffering, audio data elements are received and placed in a telephony input buffer used for anti-jitter buffering. Rather than wait until the buffer is full, the audio data elements are clocked, or played, out of the buffer at a rate slower than the normal play rate. In this way, latency due to the initial buffer fill period is reduced or eliminated. Audio data elements continue to be played out at a slower than normal rate until the buffer fill level reaches a threshold. At that time, the play rate for sending data elements out of the telephony input buffer is adjusted to the normal play rate. In an alternative embodiment of the present invention, the fill level of the telephony input buffer is controlled within a desired range by speeding up or slowing down the rate at which audio data elements are played out of the telephony input buffer. In yet another alternative embodiment, the amount of latency jitter in the packet network is measured and the size of the telephony input buffer is adjusted based upon the relative amount of jitter, such that the relative size of the buffer is reduced when the packet network is quiet, and the size of the buffer is increased when the network is relatively jittery.

Network-based traffic congestion notification service,
Tue Jun 26 18:07:07 EDT 2001
A server platform in the PSTN performs the service of calling the subscriber if the subscriber's customary commuting route is congested. The service makes an initial call when the fastest commute route is congested. It also makes additional calls each time it finds a better alternate route. The server can accommodate any subscriber commuting pattern. If a street on the subscriber's customary route is found to be congested, then the server sequentially tests additional streets having geographic coordinates nearby, dynamically searching for an alternate route that has an acceptable level of congestion. The server has a voice response unit (VRU) in the platform, to announce to the subscriber that the subscriber's customary commuting route is congested. Following an initial call to the subscriber, the server continues to search for better alternate routes having the least congestion and it calls the subscriber again if it finds a better alternate route.

Multimedia networked system detecting congestion by monitoring buffers' threshold and compensating by reducing video transmittal rate then reducing audio playback rate,
Tue Oct 13 18:05:06 EDT 1998
Disclosed is a networked multimedia information system which may be utilized to record, store and distribute multimedia presentations together with any supplemental materials that may be referenced during the presentation. The recorded presentation, together with the associated supplemental materials, may be simultaneously presented on a display containing two separate viewing windows. The effects of network congestion are minimized by prefetching audio and video data for storage in audio and video buffers. An adaptive control algorithm compensates for network congestion by dynamically varying the rate at which video frames are retrieved over the network, in response to network traffic conditions. The audio playback speed is reduced if the audio data does not arrive fast enough over the network to maintain the desired size of the audio buffer after the amount of video data transmitted across the network has been reduced to a minimum value.
