  • Patent number: 8745121
    Abstract: An approach is provided for construction and aggregation of distributed computations. A distributed computation construction infrastructure identifies an execution context bound to a user context at a device, the execution context corresponding to one or more processes executing at the device. The distributed computation construction infrastructure further causes, at least in part, decomposition of the execution context into one or more closure primitives and respective process states, wherein the one or more closure primitives represent computation closures of the one or more processes. The distributed computation construction infrastructure also causes, at least in part, serialization of the one or more closure primitives, the process states, or a combination thereof.

  • Patent number: 8718261
    Abstract: A distributed call control system is provided that can allot bandwidth amongst several call controllers. The distributed call control system includes one or more access elements that interface with a cloud that execute two or more instances of call processing servers that administer call control. The cloud members negotiate and determine bandwidth allocation amongst the members and the access elements. If an access element requires more bandwidth, the access element assesses its own needs and requests more bandwidth from the cloud. The negotiation and requests for bandwidth are accomplished with a set of dynamic and static bandwidth data that regiment the control of the bandwidth.

  • Patent number: 8688079
    Abstract: A mobile device can send a notification to place a call using a PBX (e.g., using SIP signaling) or receive a notification of call availability for the mobile device at the PBX. An authentication token is provided over a data channel for use in authenticating the mobile device when calling the PBX on a voice channel. However, when the mobile device calls the PBX (e.g., on a DNIS number, where ANI information is made available to an application server), if ANI information is found to correspond to the mobile device, the PBX can send tone(s) indicating that the mobile device can respond with an abbreviated validation tone, rather than the entirety of the authentication token. If the ANI information is not obtained or not matched, then a different tone(s) is sent, indicating to provide the authentication token. If the authentication token provided does not match or if the mobile device does not respond, the voice channel is not set up.

The subsequent CCN removes from the original list any identifiers associated with any MG in the original list of identifiers which is not capable of being used in the call by the subsequent CCN. The subsequent CCN then forms a modified list of identifiers associated with at least one MG capable of being used in a call by the originating CCN and the subsequent CCN. The subsequent CCN also selects a specified MG from the modified list and sends a first backward message from the second CCN to the originating CCN identifying the specified MG.

    Abstract: Methods, systems, and computer program products for providing telecommunication services between a SIP network and an SS7 network are disclosed. In one method, SIP/SS7 gateway receives an INVITE message from a SIP proxy server. The SIP/SS7 gateway extracts a called party number from the INVITE message and determines whether a telecommunications service is required and a type of service required for the INVITE message based on the called party number. The SIP/SS7 gateway then formulates an SS7 query to a database corresponding to the identified service type. The SIP/SS7 gateway receives a response from the database and uses data from the response to facilitate completion of the call. In one example, the SIP/SS7 gateway may forward a routing number extracted from the response back to the originating SIP proxy server. In another example, the SIP/SS7 gateway may generate a new INVITE message and forward the new INVITE message to a terminating SIP proxy server.

The file is fetched from the TCP and stored in the TS. An invite is sent to the WAN user device for initiating the file transfer session from the home network to the WAN user device. The file is transferred to the WAN user device when an acknowledgment of the invite is received from the WAN user device.

  • Patent number: 8509222
    Abstract: A method and corresponding apparatus are provided to route a call from a customer to a destination. A call setup message sent from a customer switch intended to signal a switch to perform a call routing function or request a call routing function be performed is intercepted. A call release message sent from the switch intended to signal the customer switch of network congestion is intercepted. In response to either the call setup message or the call release message being intercepted, a routing engine is queried with the destination of the call for a specific route over which to carry the call. The call setup message is modified to include the specific route. The call release message is responded to with a re-route call message that includes the specific route. The switch is directed with either the modified call setup message or re-route call message to use the specific route to carry the call from the customer to the destination.

  • Patent number: 8467516
    Abstract: A call is processed by examining a nature of address indicator in a signaling message associated with the call and allowing the call to complete in a jurisdiction associated with a national nature of address indicator if the nature of address indicator is international. A call is also processed by examining a nature of address indicator in a signaling message associated with the call. A number of digits associated with a calling party number in the signaling message is determined and the call is allowed to complete if the nature of address indicator is national and the number of digits associated with the calling party number exceeds ten.

  • Patent number: 8447022
    Abstract: A method and system for providing computer-network related information about a second party. First, the second party receives a telephone number of a first party. The second party's customer premises equipment (CPE) or elements in a telephone network then use the telephone number to index a database, which contains combinations of telephone numbers and computer-network addresses. Once the first party's computer-network address is retrieved, computer network information present at the computer-network location specified by the computer-network address can be sent to and displayed on the second party's CPE. Also, the first party's telephone number can be sent to an application in the computer network, causing the first-party-customized information to be automatically displayed on the second party's CPE.

  • Patent number: 8432902
    Abstract: A call routing device in a communication network is re-entrant to permit a set of call routing rules to be applied more than once. A routing table in the routing device has entries to indicate that an incoming call should be rerouted to the routing device to permit additional call routing rule(s) to be applied to the incoming call. A routing table is provided with entries to indicate when an incoming call should be rerouted to the routing device and how call attributes should be created/modified to achieve call routing in one or more iterations of call routing processing using the routing table. The re-entrant routing device and routing table permits a wide variety of call attributes to be used to direct call routing processing using a routing table that can have a reduced number of entries. The re-entrant routing device and routing table permits a flexible configuration for call routing in communication networks while conserving routing device resources.

  • Patent number: 8379633
    Abstract: Speech telephones are incorporated in a LAN, and, for example, when a voice telephone 5 communicates with another voice telephone 8, call control is performed through exchange of information between a PC 1 and a PC 4, juxtaposed with the voice telephones, respectively, via a LAN hub 10, a LAN switching unit 50, and a LAN hub 20. Speech data of the respective telephones 5, and 8 are packetized in the data block of a MAC frame by concentrators 30, and 40 for voice telephones, respectively, and relayed to LAN-SW interfaces 30a, and 40a. Frames having a function of absorbing fluctuation are applied to the data block of the interfaces 30a and 40a. Respective voice data packetized according to the MAC address of the MAC frame are delivered to the voice telephones 5, and 8, respectively, via the LAN switching unit 50, and the concentrators 30, and 40 for voice telephones.
