Abstract:
A computer telephony interface adapter (CTIA) for interfacing a computing device, a telephone, and a telephone network. The CTIA communicates with the telephone network using a telephone network protocol, such as a PSTN or a PBX protocol. Also, the CTIA communicates with a POTS telephone or a PBX telephone according to the telephone network protocol and with the computing device according to a data communication protocol, such as a USB or wireless protocol. The CTIA includes a controller in communication with the telephone network, the telephone, and the computing device. The controller converts communications between the telephone network protocol and the data communication protocol. In addition, the controller selectively couples the telephone into communication with the telephone network and the computing device at the same time. Thus, the CTIA enables local control over real-time shared communication among the telephone, telephone network, and computing device.
Abstract:
A modem data aggregating gateway that supports modem relay functionality for permitting reliable switching of modem traffic between a VoIP network and a data packet switch Internet Protocol (IP) network, s.a. the Internet. The modem relay aggregator may receive modem data encapsulated as Voice over IP (VoIP) data packets in accordance with a Simple Reliable Protocol Transport (SRPT) mechanism. The packet data may be error corrected and/or decompressed before being repackaged for forwarding to the ultimate destination. In the event that the destination is itself an IP device, the modem relay aggregator may forward the packets directly over the IP network. As a result, if the destination of a modem call is an IP device (such as a Web site or other Internet-enabled device) the technique eliminates two points from a processing path in which digital signal processing (DSPs) would otherwise have to perform modem protocol processing. Otherwise, minimal modem reformatting can be performed at the aggregation point.
Abstract:
A personal wireless gateway (PWG) comprises a host controller that bridges telecommunications devices using different transmission media allowing a telecommunications device designed for a particular media to be used to communicate over any other available media. Corded and cordless plain old telephones (POTS) may initiate and receive telephone calls over the public switched network (PSTN) or may be bridged to a mobile telephone to initiate and receive telephone calls via the mobile telephone network. A telephone configured for voice over IP (VoIP) may initiate and receive telephone calls via a broadband connection, the PTSN, or a mobile telephone network. A broadband connection may also be used to support high-speed data exchange between the Internet and one or more computer (e.g., laptop, general purpose computer, personal data assistant) via a wireless LAN or via a mobile telephone connected to a wireless data network The PWG is adapted to provide the location of the PWG to an emergency assistance service when an emergency assistance number is called from any device during predefined intervals and/or if the caller is unable to speak. Additionally, the PWG provides devices without fixed locations the attribute of a known location. The location information may be stored expressly by the user or gleaned from the user profile information. By way of illustration and not as a limitation, the emergency assistance service may be a “911” operator.
Abstract:
A network stream transmitter receives a transport stream having content packets and packets to be filtered out and is adapted to selectively encapsulate content packets into network frames.
Abstract:
The invention concerns a residential gateway device designed for a decentralized client equipment and comprising converting means for providing interoperability between to separate IP telephony services.
Abstract:
A signal processing system which discriminates between voice signals and data signals modulated by a voiceband carrier. The signal processing system includes a voice exchange, a data exchange and a call discriminator. The voice exchange is capable of exchanging voice signals between a switched circuit network and a packet based network. The signal processing system also includes a data exchange capable of exchanging data signals modulated by a voiceband carrier on the switched circuit network with unmodulated data signal packets on the packet based network. The data exchange is performed by demodulating data signals from the switched circuit network for transmission on the packet based network, and modulating data signal packets from the packet based network for transmission on the switched circuit network. The call discriminator is used to selectively enable the voice exchange and data exchange.
Abstract:
A method and IP Multimedia Subsystem (IMS) gateway for establishing a unicast media session between a media receiver and a media source in an IMS network via a Network Address Translation (NAT) function acting on behalf of the media receiver. A media source controller in the IMS sends a Session Initiation Protocol (SIP) INVITE message to the media receiver to identify the media source. The media receiver obtains NAT bindings for the unicast media session, and the session is established between the media receiver and the media source.
Abstract:
There is provided a communication method for the receiving a first call-initiation request, generating a second call-initiation request in response to the first call-initiation request and generating a third call-initiation request in response to the first call-initiation request. Moreover, there is provided a communication method comprising receiving call-session information, separating the call-session information into core audio information and into supplementary information, routing core audio information on a first path and routing supplemental information on a second path. Further, there is provided a communication method, comprising receiving core audio information on a first communication path, receiving audio-enhancement information on a second communication path, uncompressing audio-enhancement information, combining core audio information with audio-enhancement information to generate combined audio information and providing combined audio information to audio terminals.
Abstract:
System, methods, and apparatus are provided for wireless vehicle-to-vehicle sharing of multimedia data. The system includes a data storage device configured to store multimedia data packets transmitted by a system broadcast, a processor coupled to the data storage device and configured to determine a non-received group of multimedia data packets based on the stored multimedia data packets of the system broadcast, and a transceiver coupled to the processor. The transceiver is configured to receive multimedia data packets transmitted from the system broadcast and multimedia data packets transmitted from a system vehicle in response to the request signal. The method includes the steps of determining non-received multimedia data packets based on a system broadcast in a first wireless protocol, and requesting multimedia data packets of the non-received multimedia data packets in a second wireless protocol from system vehicles.
Abstract:
The present invention proposes a solution for providing IMS services to users having circuit-switched controlled terminal being not adapted to provide IMS services to the users. In particular, it is proposed, in order to allow IMS to take the full call and service control, to place a user agent being responsible for the user ported to the IMS in a new node type called Mobile Access Gateway Control Function (MAGCF). This new node combines the logical functionality of a cellular switching center and the logical functionality of IMS. Further it is proposed to enhance a user's register, like HLR, to provide also information about the availability of a MAGCF node and about whether a particular user is enabled to use the MAGCF functionality.
