Abstract: A system and method for a terrestrial IP network for efficient transmissions within a satellite-terrestrial network. The terrestrial network of a satellite-terrestrial telecommunications system provides for IP signaling between satellite access nodes without the use of dedicated, circuit switched trunks therebetween. The terrestrial network configuration provides for mobile services switching center redundancy and load sharing, as well as direct packet routing between satellite access nodes. Alternatively, a signaling gateway may be interposed on dedicated satellite access node links for converting inter-satellite access node traffic into an IP signaling format for efficient utilization of the direct links.

Abstract: A communication network having multiple codecs communicating voice calls between an originating network and a terminating network. The communication network includes an originating codec and a terminating codec. The network provides signaling indicating the decoding algorithm to the originating network, and indicating the encoding algorithm to the terminating network. The original encoding algorithms and the original decoding algorithms are then altered from the standard as a function of this signaling to produce a best fit encoding matching to improve voice quality.

Abstract: Provided is a system, method, and computer program for transmitting, across a mobile communication network, the occurrence of silence in a communication channel. The system generally comprises a first Media Gateway (MGW), which could be a transmission control node (first TCN), for executing a silence transmission algorithm, and a second MGW, such as a second transmission control node (second TCN), for executing a comfort noise generating algorithm. One method detects silence in a communications channel and then transmits a network silence indicator (SID). Another method receives the network SID and then produces a comfort noise. The computer program utilizes a query module for detecting a comfort noise production module in a destination MGW, and a network SID transmission module to send a network SID across a PLMN.

Abstract: An air bag calibrator that is used to calibrate a plurality of seat sensors within a seat simultaneously. The calibrator uses controlled pressure contained within an air bladder and an air press cylinder to apply a controlled force across an entire seat surface that actuates all of the seat sensors in a consistent and repeatable manner, a major improvement over existing seat calibration methods. This is accomplished by loading a seat onto the calibrator, recording a baseline seat sensor value for each of the seat sensors, extending the air press cylinder to an extended position and applying a controlled force across the entire seat surface. The air pressure in the air bladder is then increased or decreased to a target pressure for a predetermined time, at which time an actuated seat sensor values for each of the seat sensors is recorded.

When the signals are received at the central office, they are accordingly reassembled.

Abstract: The present invention provides a system and method for reliably transferring Dual Tone Multiple Frequency (DTMF) signals originating at a MS through an IP based GSM network. In general, when a MS sends a DTMF request, it is processed in the IP network by a logical application module in a MSC, which, based on the disclosed processing, activates another logical application module in an appropriate gateway (for independent, remote, tone generation), and then the logical application module in the gateway directs the production of the DTMF signal towards the interworking or destination network.

Abstract: A system and method for providing dynamic demand based management of traffic channel allocation in a mobile communications network providing high-speed circuit-switched data services. Traffic channel allocation for the data services is controlled dynamically by an InterWorking Function (IWF) which monitors the status of the associated buffers. The need for additional radio resources and the under-utilization of current radio resources is automatically detected by the IWF which respectively responds by initiating new traffic channel assignments via the Mobile Services switching Center or requesting the Mobile Services switching center deallocate an appropriate portion of the allocated radio spectrum.

Abstract: A telecommunications system and method is disclosed for providing a more accurate measurement of the cumulative path delay present in a call to enable switches to make an informed decision as to the routing method to use. In one embodiment, the Integrated Services Digital Network User Part (ISUP) satellite hop counter field is expanded to include three fields, one for each type of delay: geostationary satellite hops, mid-earth orbit satellite hops and low-earth orbit satellite hops. In an alternative embodiment, a cumulative delay value in milliseconds or centiseconds, instead of the number of satellite hops, can be included in the expanded ISUP satellite hop counter field.

Abstract: A telecommunications network architecture and method of providing failover operations between mobile switching centers (MSCs). A plurality of MSCs and at least one base station controller (BSC) are connected to an Internet Protocol (IP) network in which transmission paths and control paths are logically separated. The BSC reports to a primary MSC and includes an alternative MSC list identifying at least one backup MSC for the primary MSC. The BSC determines when the primary MSC has failed, and utilizes a control path in the IP network to notify the backup MSC that the BSC has switched its reporting to the backup MSC. The BSC also utilizes a transmission path in the IP network to send mobile station communications from the BSC to the backup MSC. Mobile station location updating requests are sent from the backup MSC to a home location register (HLR). The requests include a new element that informs the HLR that the backup MSC is now serving the mobile station due to a failure of the primary MSC.

Abstract: Methods and arrangements are provided that allow for an Internet gateway to directly request or otherwise access routing and/or location information within a home location register (HLR) within a mobile communications network. This allows for Voice over Internet Protocol (VoIP) communications to be conducted without requiring excessive signaling and/or processing within the mobile communications network. The methods and arrangements can be provided in the form of a standalone node or incorporated into existing nodes, such as, for example, a gateway node within the Internet or a similar network. Verification and/or policing functions are also provided to limit access to the routing and/or location information.

Abstract: A circuit breaker has a set of remotely controllable secondary contacts connected in series with the main contacts which provide overcurrent protection. The secondary contacts are opened and closed by a latching solenoid having a close coil and an open coil which are separately connected to switched terminals of a first switch. A voltage source, which may be ac, dc or pulsed, is connected to the common terminal of the first switch through a rectifier. The first switch is coupled to the plunger of the latching solenoid which opens and closes the set of secondary contacts and enables the coil which operates the set of secondary contacts to the opposite state. Energization of the enabled coil is completed by additional, remotely located switches connected between each coil and ground. A status line connected to one of the switched terminals of the first switch is energized when the associated coil is enabled to indicate the open/close status of the set of secondary contacts.

Abstract: An Internet Protocol (IP)-based radio telecommunications network and method of providing data services to a mobile terminal. An Internet Protocol Shared Interworking Function (IP-SIWF) is implemented in the network, and is controlled from a Mobile Switching Center (MSC) utilizing the Media Gateway Control Protocol (MGCP) device control protocol. When a data call carrying a data payload is originated by a mobile terminal, the data call is transported utilizing radio access and radio link protocols to the IP-SIWF. The radio access and radio link protocols are terminated in the IP-SIWF, and the data payload is transported thereafter utilizing a real time protocol over a User Datagram Protocol (UDP) and an IP protocol layer.
