  • Patent number: 7023794
    Abstract: 18A method and system for controlling the switching and control operation of at least one of an Softswitch system, an Signal Transfer Points (STP) and a gateway (GW) (e.g., in a SS7 signaling environment). By providing support for redundancy, a second switch system can take over the routing and control operations of a first switch system when the first switch system experiences difficulty. Difficulty may be any one of several forms (e.g., switch crash, congestion, hardware failure).

  • Publication number: 20050286693
    Abstract: Embodiments of the present invention relate to billing for services in an Advanced Intelligent Network (AIN) environment. A first call is received at a service node from a service switching point located in the AIN. A second call is established through the service switching point to a called party. The first call is bridged with the second call and the bridged call is monitored for signaling information. The bridged call is processed based on the monitored signaling information. A billing module is created for the processed call at the service node. The billing module may include service values related to billing information for the processed call. The processed call may be merged back into the service switching point and the created billing module for the processed call may be sent to the service switching point for ultimate delivery to a billing system.

  • Publication number: 20040120499
    Abstract: A method for providing communication service in an Advanced Intelligent Network environment comprises receiving an alert message the originates from a database, the alert message including a protocol parameter; identifying a protocol that controls communication between the intelligent peripheral and the database in a protocol identifying by the protocol parameter, the protocol being stored in a database in the IP containing a plurality of protocols and a plurality of protocol parameters, each protocol in the plurality of protocols being correlated with a unique protocol parameter from the plurality of protocol parameters; and executing the protocol.

  • Publication number: 20020067817
    Abstract: Systems and methods provide service on a network, receiving from a database a response to a query, processing the response to obtain a set of instructions that are adapted to be executable by a switch, and then controlling the switch in accordance with the instructions.
