  • Patent number: 7995738
    Abstract: When a call offer is received by a telecommunications peering network destined for a telephone number maintained within a peering database, the telecommunications peering network attempts to route the call directly to the peering partner telecommunications (e.g., broadband, voice over internet protocol, etc.) equipment. If the route fails with a corresponding destination unreachable failure code, the telecommunications peering network can attempt to determine whether or not the telephone number has been ported to a different provider. If the telecommunications peering network determines that the telephone number has been ported, the telecommunications peering network removes the telephone number from the peering database.

  • Patent number: 7936866
    Abstract: Methods, systems, and computer program products for routing query messages associated with prepaid subscribers in a number portability environment are disclosed. One method may include sending a registration message to an HLR. At the HLR, the ID or address of an STP is inserted as the prepaid SCP ID in a registration response message. The registration response message is sent to the MSC/VLR that originated the registration message. This action forces the VLR to send prepaid query messages to the STP, rather than to the prepaid SCP. When the STP receives a query message relating to call originating from the prepaid subscriber, the STP performs a number portability database lookup and determines the routing number corresponding to the called subscriber and the prepaid SCP corresponding to the calling subscriber. The STP then routes the query message to the appropriate prepaid SCP.

  • Patent number: 7929683
    Abstract: To route calls in a wireless network in which an NPA split has been implemented, an intelligent router mediates NPA mismatches by modifying requests for routing information according to a rule set based on the update status of the HLR or other network element to which the routing requests are directed. According to whether the intended network element has been updated to recognize a new NPA in the directory number, the appropriate version of the directory number is included in the routing request, regardless of whether the old or the new version of the directory was actually dialed. In some embodiments, the intelligent router first modifies the routing request to include the new version of the directory number, and upon receiving an error from the intended element, resends the request with the old version. Receiving an error may prompt the intelligent router to trigger an update of the intended element.

  • Patent number: 7885398
    Abstract: This invention provides the ability to load balance calls in a communications network using a certain criterion, such as a user-specified call priority, or the call service category. The method is applied when selecting a route for a new call or for re-balancing the calls across a network. When the user-specified call priority is used, the aggregated number of calls with the same priority or service category is calculated for all possible routes the new call may use. The aggregated number of calls is then divided by the number of hops in the respective routes; the route with the smallest ratio is selected for the new call. Re-balancing is performed by re-routing the calls in such a way as to obtain a similar number of calls of the same priority, or service category along all possible routes.

  • Patent number: 7844261
    Abstract: Number portability is a service where a subscriber can keep his old telephone number within a portability cluster and thus retain easy contactibility. Because of number portability, a called address, i.e. B-number, no longer refers to the subscription network/number range owner and the old rule “the number range of the called party reveals the tariff level” is no longer valid. To overcome this defect all intelligent network-like service invocation requests are routed (3-2) via a network node performing a number portability function to the network node controlling the service. The node performing the number portability function performs (3-3) a mapping of the B-number and relays (3-4) the service invocation requests indicating the subscription network/number range owner.

  • Patent number: 7804952
    Abstract: This invention provides the ability to load balance calls in a communications network using a certain criterion, such as a user-specified call priority, or the call class of service. The method is applied when selecting a route for a new call or for re-balancing the calls across a network. When the user-specified call priority is used, the aggregated number of calls with the same priority or class of service is calculated for all possible routes the new call may use. The aggregated number of calls is then divided by the number of hops in the respective routes; the route with the smallest ratio is selected for the new call. Re-balancing is performed by re-routing the calls in such a way as to obtain a similar number of calls of the same priority, or class of service, along all possible routes.

  • Patent number: 7768996
    Abstract: A method for re-querying for routing information is disclosed. The method transmits an initial admission query to a gatekeeper or a request for routing information and receives an admission confirmation or routing information response with a destination address. The method then tries to establish a connection with the destination address. Upon reception of a call failure message including a failure cause, the method, optionally, increments a counter and transmits a re-query to the gatekeeper or other routing entity, and the re-query includes the failure cause and, optionally, a value of the query counter.

  • Patent number: 7764778
    Abstract: A menu routing service routes calls made to a customer's toll-free number according to customized routing instructions, including instructions for routing calls originating in a non-domestic country. An international gateway receives a call to the toll-free number and populates a portion of a calling party number field with data indicating that the call originated in a non-domestic country. A network switch receives the call from the gateway based on at least an identification of a carrier associated with the toll-free number. A customized routing service platform receives the call and the non-domestic call origination data from the network switch. The platform determines a destination number based on the non-domestic call origination data and routing instructions received from a web server, accessible by the customer via a packet switched data network. The platform forwards the destination number to the network switch for routing the call to the destination number.

  • Patent number: 7764777
    Abstract: A caller ID based call routing feature is described for blocked and non-blocked caller ID's. A processing system in the public switched telephone network (PSTN) receives first identifying information for identify the source of a telephone call and associates additional information stored in a memory with the first identifying information. The additional information may be information about the calling party initially downloaded to the memory by a subscriber. Once retrieved from the memory by the processing system, the additional information may then be transmitted to the subscriber via the Internet for display on a monitor or to the subscriber's telephone for display on a telephone display. Another feature described is a branch calling feature where the subscriber may program a processing system within the PSTN to forward an incoming call to two or more end units (e.g., telephones) simultaneously.
