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.
Abstract:
A digital telecommunications system, a method of managing a communications network in such a system and a program product for managing audio transmission in a digital communications system. A softswitch manages communications between devices at network endpoints, e.g., session initiation protocol (SIP) devices, and detects when communications include a non-human, e.g., an audio system, at an endpoint. The softswitch selects conversational communications for calls between voice devices and messaging communications parameters with lower overhead for communications with an audio system, e.g., messaging systems such as voice mail.
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.
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.
Abstract:
The present disclosure is a method and system for managing communication traffic of devices based upon available power for a device. A method for managing communication traffic may include receiving available power resource information from a device and routing communication intended for the device based upon available power of the device.
Abstract:
The present invention relates to methods and apparatuses for speech signal encoding and decoding. In accordance with the invention, a discrete time speech signal is encoded by identifying a speech element in the speech signal. If the speech element is identified for the first time, the encoder (108) creates a unique tag representing the speech element and an associating between the speech element and the unique tag in a memory and transmits the speech element in discrete time form and the tag and an indication that the tag is to represent the speech element to a decoder (118). If the speech element was identified before, the encoder (108) obtains a unique tag representing the speech element from the memory, removes the speech element from the speech signal and transmits the unique tag representing the speech element as obtained from the memory.

Abstract:
A Voice over Internet Protocol (VoIP) communications system, a method of managing a communications network in such a system and a program product therefore. The system/network includes an ENERGY STAR (E-star) aware softswitch and E-star compliant communications devices at system endpoints. The E-star aware softswitch allows E-star compliant communications devices to enter and remain in power saving mode. The E-star aware softswitch spools messages and forwards only selected messages (e.g., calls) to the devices in power saving mode. When the E-star compliant communications devices exit power saving mode, the E-star aware softswitch forwards spooled messages.
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.
