  • Patent number: 7688962
    Abstract: The present invention provides telephone line subscribers the benefits of simultaneous ringing service without wasting telephone network resources. When a simultaneous ringing service subscriber's wireline telephone (the primary telephone) receives an incoming call, a service switching point connected to the primary telephone sends a query to a service control point. The service control point then checks the busy/idle status of the primary telephone as well as the subscriber's wireless telephone (the secondary telephone). If the primary and the secondary telephones are idle and can receive the call, the service control point instructs the service switching point to forward the call to a service node. Otherwise, the service switching point is authorized to terminate the call. When the service node receives the call from the service switching point, it generates two calls simultaneously: one to the primary telephone and one to the secondary telephone.

  • Patent number: 7411985
    Abstract: A low complexity packet loss concealment method for use in voice-over-IP speech transmission calculates a cross-correlation of previous speech data to estimate the pitch period of the previous speech when speech frames have been lost. A tap interval used to calculate the cross-correlation is dynamically adapted, thereby reducing the computational complexity of the process. In addition, the pitch period estimation is bypassed completely when it is determined not to be necessary, as a result of the speech being unvoiced or silence. A waveform “bending” operation is performed into the current frame without inserting any algorithmic delay into each frame.

  • Patent number: 7394897
    Abstract: A method and system for routing service calls made from lines resold to a competitive service provider includes advanced intelligent network and standard switching functionality. The call may be made into an AIN service switching point (60) or a non-AIN switch (62-64). All calls are routed to an AIN hub (190), such as a service switching point, via a trunk group. The AIN or non-AIN switch may access a line class code table (160-164) to determine the proper routing information. Calls made from resold lines are routed to the AIN hub (190). Once the call is routed to the AIN hub, a trigger (187) provisioned on the AIN hub and assigned to the incoming trunk group causes the hub to suspend the call and launch a query to a service control point (200). The query includes the directory number of the resold calling line and the originally dialed number. The SCP (670) accesses a data-base (675) containing directory numbers for resold lines and identifiers for competitive service providers.

  • Patent number: 7362851
    Abstract: A system for providing location ID services for telephone calls transfers location data describing the location of the calling device to the called device. Rather than or in addition to providing the name and telephone number as is done through the conventional caller ID service, the location of the calling device is displayed by the called device including the zip code, the longitude and latitude planar coordinates, or the street address. Existing advanced intelligent network infrastructure may be adapted to provide the location ID service, such as by providing location data queries from a signal switching point to a signal control point. The signal control point has access to a CNAM database containing location ID data fields in addition to conventional caller ID data.

  • Patent number: 7289606
    Abstract: Multi-modal applications are capable of interacting with a user in a voice mode, a visual mode, and/or other modes of communication. Mode swapping refers to the process of changing from one mode of communication (or one combination of modes) to another. Mode swapping may be initiated by a user, by an application, or by another entity. Mode swapping may be performed “adaptively,” in that an entity monitors the effectiveness of a communication mode and initiates a mode swap if communication is proceeding non-optimally in the current mode. Mode swapping may be performed by dropping a call to a telephone terminal in the currently-open mode and placing a call to that same device in another mode. In one embodiment, logic for mode swapping resides on a gateway proxy that mediates communication between an application and a telephone terminal.

  • Patent number: 7289493
    Abstract: A method and system, employing IP telephony, for providing continuous, uninterrupted voice communications during disaster conditions wherein the disaster site telephone infrastructure has been rendered inoperable or inaccessible. The system uses Voice over IP (VoIP) and emerging IP telephony standards to enable users to receive telephone calls, normally destined for their work phone, at a personal computer terminal connected to the Internet. Users can also place calls from their terminal to the PSTN or to other users on the system. Combining telephone line redirection with IP telephony capabilities enables the construction of a system that provides users with unlimited flexibility in responding to a severe business interruption with full voice communications. The system can be customized so calling parties will be presented with precisely the same greetings and messages, for each user telephone extension, that were present in the disaster site's telephone system.

  • Patent number: 7035391
    Abstract: Communication between a service switching point (SSP) and an external (or stand alone) Intelligent Peripheral (IP) has not been defined by any of the standard bodies. ITU-T Q.1600 and ETSI 300 374-1 defines the network configuration of SCP, SSP and stand-alone IP units using SS7 ISUP connection, but ITU-T Q.1600 and ETSI 300 374-1 does not specify in detail the SS7 ISUP messages for bi-directional communication between a SSP and an IP unit. This invention details the message flow between a SCP, a SSP and an ISUP IP unit, especially in the messages between the SSP and IP unit using SS7 ISUP protocol. With the signaling method of the present invention, SCP can send INAP operations, such as PA, PCUI to instruct an external IP unit to play an announcement or collect user information, then an IP unit can send back the related operations back to SCP. In this case, the resource of the IP unit can be shared by other switches and SSPs in the network.

  • Patent number: 6870916
    Abstract: In a multimedia communications system (100), a conference establishment server coordinates the scheduling of a conference call. The server receives request for conference calls (202). The request includes a list of participants and may include an indication of the resources necessary and any rules for the conference call. The request may indicate critical resources or participants that are required for the call. Based on the request, the server determines a conference time and notifies participants of the time (204, 206, 210). Prior to conference time, participants are reminded of the time and automatically connected to the call. The server may check the status of users on the telecommunications network to determine availability. If a critical participant or resource is unavailable at conference time, the conference may be cancelled with notification to the participants.

  • Patent number: 6826273
    Abstract: Congestion problems in networks are alleviated with a method that works toward insuring the unused capacity will always exist in elements of a network that are resources which are shared by a plurality of users and which, consequently, can be overloaded. In response to each a request to establish a connection over a path in the network, pursuant to a predetermined algorithm method either services the request, declines to service the request, or services the request after dropping an established connection. In one embodiment, when unused cavity on the path is above a preselected level, all requests are services. What unused capacity falls below a preselected threshold, a probabilistic approach is taken as to service the request or not, and as whether to drop an existing call in order to service the request.
