Conversion Between Signaling Protocols Patents (Class 370/467)
  • Patent number: 8064354
    Abstract: A process for routing a call between an ingress point and an egress point is based on an identifier, such as a number, assigned to the egress point and a registry in which identifiers are stored. A routing component receives the call from the ingress point and consults the registry to determine if an entry with the identifier of the egress point being called is stored therein. If a corresponding entry exists, a delivery route for routing the call to the egress point is determined. The delivery route may be a first path to the egress point if available. If the first path is not available, one or more secondary paths are determined, where one is utilized for sending the call to the egress point. The utilized secondary path may be the most optimal path for the call based upon established preferences and call features.

  • Patent number: 8060067
    Abstract: Efficient routing of a message over a data network. A first communication device sends a message to a telemetry gateway or short message arbitrator. The telemetry gateway or short message arbitrator determines the communication protocol of the first communication device and the communication protocol of a second communication device. The telemetry gateway or short message arbitrator converts the message to a data format compatible with the second communication device, wherein the message is converted to one of at least three different communication protocols. The telemetry gateway or short message arbitrator then forwards the message for receipt by the second communication device. The telemetry gateway or short message arbitrator can convert and forward the message without completing a store and forward process.

  • Patent number: 8054825
    Abstract: The invention relates to a method for transferring a call between a telecommunications network and a data network. Between the data network and the telecommunications network an internetwork computer (gateway) is arranged, by which voice data of the call is converted from a format used in the telecommunications network into a format used in the data network, and conversely. Signaling data of the call is processed by a data processing device arranged in the data network. In order to make full use of the available functions of a signaling channel in telecommunications networks, even with voice connections that are partially over a data network, it is proposed that the signaling data be transferred bit-transparently between the gateway and the data processing device.

  • Patent number: 8045564
    Abstract: Mechanisms are disclosed for detecting protocols independently of the ports used by streams associated with the protocols or applications that may send out such streams. The detecting may entail using a content filter that is hosted on a networking stack, where the content filter may be composed of a stream buffer and handlers for detecting the protocols. The handlers may be further used to modify streams incoming to a port or streams outgoing from an application. The handlers can modify the streams in a variety of ways, including reading, inserting, replacing, deleting, and completing data in the streams according to some policy criteria, such as those set by parental controls. Individual handlers may be selected from a plurality or set of handlers so that they can be matched up to the appropriate streams.

  • Patent number: 8037196
    Abstract: A method for supporting communication between communication devices (102, 104, 106) having inconsistent protocols, such as may result from protocol changes or upgrades. Protocol registers (302, 304) maintained in association with the communication devices contain respective first and second protocols (e.g., current and previous protocols) of the communication devices. A sending (or receiving) device, upon being upgraded from protocol C to N, updates (206) its protocol register to indicate N as the current protocol and C as the previous protocol. The device initially attempts to send (222) a message (or attempts 212 to recognize a message) using its current protocol N and, if that fails, the device sends (230) (or attempts 216 to recognize the message) using its previous protocol C.

  • Patent number: 7936718
    Abstract: A wireless telephone without IP capability nonetheless communicates with an infrastructure that uses IP. Virtual IP endpoints, such as Base Stations (BTS), not only communicate with the infrastructure using IP and with the telephone using over-the-air protocol, such as Code Division Multiple Access (CDMA), but one of the endpoints also selects the best frame over a call received by multiple endpoints, alleviating the need for a Base Station Controller (BSC) in the infrastructure. A handoff assist entity causes frame selection to be transferred to a second BTS in accordance with a handoff algorithm.

  • Patent number: 7920831
    Abstract: Conveying Push-To-Talk and Push-To-Signal (PTT/PTS) information over an IP network through signaling bits defined in and propagated with the Real-Time Protocol (RTP) stream allows the PTT/PTS information to remain synchronized with the voice packets of the stream. The maintenance of synchronization of PTT/PTS signals and voice packets eliminates problems arising from failure of synchronization between the two classes of packets, notably the “shoot/don't shoot” problem. The signaling bits employed were formerly used to convey legacy network information, but are no longer in active use in the Voice-over-IP (VoIP) realm, since VoIP provides alternative pathways for their information.

  • Patent number: 7920590
    Abstract: A mobile station (100) and a compression/decompression node in a wireless network (5), preferably the GGSN 30 (30), agree on whether to apply compression/decompression, and what compression/decompression scheme to use either by pre-configuration (when the GGSN 30 is in the home network of the mobile terminal) or by signalling (when the GGSN 30 is in a visited or a roamed-to network). Additional information, such as a profile-specific dictionary, may be used to increase the compression efficiency, particularly during start-up. Dynamic data can also be accommodated. The compression/decompression may be turned on and off on a packet-by-packet basis, depending on whether the compression actually results in a smaller packet. A compressed/uncompressed indicator bit or bits can be inserted explicitly on a per packet basis, and/or the compressed/uncompressed indication can be derived implicitly.

  • Patent number: 7916749
    Abstract: A method and apparatus are provided for jointly encoding bits containing information about an existing modulation technique or an existing antenna transmission technique in order to extend signaling to include new information about an additional modulation technique or the use of an additional antenna transmission technique without having to increase the number of bits transmitted in the signaling; and conveying the new information in unused combinations of the encoded bits. The signaling may take the form of a high speed shared control channel (HS-SCCH) that forms part of a high speed downlink packet access (HSDPA). In some embodiments, the existing modulation technique may include quadrature phase shift keying (QPSK), 16 quadrature amplitude modulation (16QAM), or some combination thereof, and the additional modulation technique may include 64 quadrature amplitude modulation (64QAM).
