  • Publication number: 20160360152
    Abstract: A method for outputting sensitive data to a user includes a communication terminal checking to determine whether at least a portion of the sensitive data is to be outputted by determining whether the communication terminal is in one of a plurality of predefined communication configurations for outputting the sensitive data. If the communication terminal is found to be a first configuration, the communication terminal transmits the sensitive data so that at least one of the video data and the audio data is output to the user via at least one peripheral device connected to the communication terminal. If the communication terminal is in a second configuration, the communication terminal performs at least one security action to help further protect the sensitive data.

  • Patent number: 9467688
    Abstract: A method and apparatus that tests video quality includes a superimposing of at least one code to a video that is to be transmitted by a communication device to another communication device. The at least one code is transmitted such that the superimposed at least one code is extractable and readable from the decoded video by the device that receives the transmitted video. The extracted at least one code may then be read to determine the quality level of the transmitted video. The determination of quality for the received video may be based upon one or more tests performed using at least one code extracted from the received video.

  • Publication number: 20160198040
    Abstract: The invention relates to a communication system and a method of maintaining audio communication in a congested communication channel currently bearing the transmission of speech in audio communication between a sender side and a receiver side, the communication channel having at least one signaling channel and at least one payload channel having a quality of service. During the audio communication the quality of service of the payload channel is monitored. If the quality of service of the payload channel is below a threshold the speech at the respective sender side is converted to text; and transmitted over the retained communication channel to the respective receiver side. The text may be converted back to speech at the receiver side.

  • Publication number: 20160165179
    Abstract: A communication system, method and communication terminal are configured to permit bandwidth reduction when communication partners are engaged in a communication session. In one embodiment, a communication terminal such as a cellular phone or tablet may turn off at least one of its display and camera sensor within a predetermined amount of time when the terminal is detected as being positioned near a user's ear via at least one sensor of the terminal. In some embodiments, the communication terminal may also transmit one or more messages to communication devices of communication partners engaged in the communication session to inform those devices that video transmissions should no longer be sent to the communication terminal. The communication terminal and other communication devices involved in the communication session may also stop transmitting video as a result of the detection of the communication terminal being positioned near a user's ear.

  • Patent number: 9137345
    Abstract: A communication terminal, system and method utilize a communication device that activates a speech to text application so that subsequent audio that is received from a caller is converted into text. A caller may then provide audio in response to a question. A caller may send input by pressing a button on a communication device for example, to activate the speech to text application, speak an answer, and then press a button to indicate that an answer to a question is complete. The spoken answer may be converted into text and may then be stored, parsed, and then assigned to an object representing the question posed to a caller. The stored text assigned to the object representing the question may then be used to populate different forms or databases for subsequent use or for displaying to a user via a display device of that person's computer device.

  • Publication number: 20140379343
    Abstract: A method and apparatus that filters audio data received from a speaking person that includes a specific filter for that speaker. The audio characteristics of the speaker's voice may be collected and the specific filter may be formed to reduce noise while also enhancing voice quality. For instance, if a speaker's voice does not contain specific frequencies, then a filter may cancel the noise at such frequencies to ease noise cancellation and reduce processing sound spectrum for cleaning that is not needed. Additionally, the strength frequencies of a speaker's voice may be identified from the collected audio characteristics and those spectrums can be filtered with finer granularity to provide a speaker specific filter that enhances the voice quality of the speaker's voice data that is transmitted or output by a communication device. The audio data may also be output based upon a user's predefined hearing spectrum.

  • Patent number: 8571539
    Abstract: A method and apparatus for transmitting a notification of a shutdown event includes a communication terminal turning off or otherwise shutting down and prior to turning off sending a notification to a third party device such as an access point, base station, server, or proxy, that identifies information relating to the shutting down of the terminal such as a location, purpose for the shutdown and other relevant information. Subsequent devices that attempt to establish a communication connection with the terminal may then receive the notification or information from the notification via the third party device. The sending of information relating to the notification or the notification by the third party can also trigger another action. One example of such an action is the forwarding of the communication connection request to another device to receive that request based upon a predefined rule or a predefined forwarding address.

  • Publication number: 20110103565
    Abstract: Providing service resolution between a calling subscriber and a called subscriber of a telecommunications network, wherein a call of a calling subscriber device of the calling subscriber includes content for at least a first capability and a second capability and called subscriber device is capable of only a subset of the first and second capabilities. The calling subscriber device requests a call with the first and second capabilities. The called subscriber device broadcasts a signal to at least one peripheral device and requests a response from devices that are capable of the subset capability. A peripheral device responds that it has the requested subset capability. The called subscriber device splits the media received and sends the media corresponding to the requested subset capability to the peripheral device for processing.

  • Publication number: 20100166167
    Abstract: A method and an apparatus are provided for managing subscriber profile information. The method provides a database containing a global subscriber profile, wherein the global subscriber profile includes the subscriber profile information. A network element serving a subscriber terminal requests information from the global subscriber profile associated with a subscriber identity presented by the subscriber terminal. The method then determines if all global subscriber profile information required for performing a function of the network element is compatible with the network element and transforms incompatible information into information compatible with the network element.

  • Patent number: 7496088
    Abstract: A method for establishing a call in a telecommunications network that has first and second packet network sections, a wide area packet network, and a TDM transit network section. Subscribers'terminal equipment is addressable by directory numbers, and calls to subscribers are always routed through the TDM transit network. During TDM call setup at least one message or information element is conveyed to the second packet network section which is indicative of the first terminal equipment's packet capabilities and/or an address of a first controlling device controlling the call in the first packet network section. The message or information element is received at a second controlling device controlling the call in the second packet network section. Using the information extracted from the message or information element a second connection between the first and second terminal equipment through the wide area packet network is established by the controlling devices.
