The present invention describes a system and method for communicating voice and data over a packet-switched network that is adapted to coexist and communicate with a legacy PSTN. The system permits packet switching of voice calls and data calls through a data network from and to any of a LEC, a customer facility or a direct IP connection on the data network. The system includes soft switch sites, gateway sites, a data network, a provisioning component, a network event component and a network management component. The system interfaces with customer facilities (e.g., a PBX), carrier facilities (e.g., a LEC) and legacy signaling networks (e.g., SS7) to handle calls between any combination of on-network and off-network callers.The soft switch sites provide the core call processing for the voice network architecture. The soft switch sites manage the gateway sites in a preferred embodiment, using a protocol such as the Internet Protocol Device Control (IPDC) protocol to request the set-up and tear-down of calls. The gateway sites originate and terminate calls between calling parties and called parties through the data network. The gateway sites include network access devices to provide access to network resources. The data network connects one or more of the soft switch sites to one or more of the gateway sites. The provisioning and network event component collects call events recorded at the soft switch sites. The network management component includes a network operations center (NOC) for centralized network management.

A system for sending a data packet from a messaging device to a receiving device in a signalling network (210) is described. The system comprises a distributed service center (255) a message receiving service center (290), a plurality of signalling units (260, 270) for passing the data packet to the receiving device, a central routing logic (280) for routing the data packets and a closed network connecting at least the central routing logic (280) and the plurality of signalling units (260, 270). Also disclosed is a corresponding method for sending a data packet from a messaging device to a receiving device.

A system and method for recognizing patterns in wireless device locations using wireless device location data derived from a communications signaling network is provided. By using wireless network supported signaling operations and messages, location data concerning the whereabouts of wireless devices, and hence wireless device users, may be obtained. The location data derived from the communications signaling network may be statistically analyzed to reveal potential geographic patterns that may indicate meaningful behaviors of the purported users of the wireless devices.

A method of preparing a programmable integrated circuit device for configuration using a high-level language includes compiling a plurality of virtual programmable devices from descriptions in said high-level language. The compiling includes compiling configurations of configurable routing resources from programmable resources of said programmable integrated circuit device, and compiling configurations of a plurality of complex function blocks from programmable resources of said programmable integrated circuit device. A machine-readable data storage medium may be encoded with a library of such compiled configurations. A virtual programmable device may include a stall signal network and routing switches of the virtual programmable device may include stall signal inputs and outputs.

A signaling network routing node, such as a signaling system 7 (SS7) / Internet protocol (IP) gateway, is adapted to perform global title translation (GTT) or other processing on received signaling messages and route the signaling messages to a member of a load sharing group using a threshold-based weighted load sharing algorithm. In the event that one of the signaling destinations in the load sharing group becomes unavailable, signaling message traffic is redistributed evenly among the remaining available members of the load sharing group in a manner such that a maximum load sharing weight threshold value associated with each group member is not exceeded. If a load sharing group member becomes unavailable, and the resulting recalculated load sharing weights of the remaining available members sum to less than 100%, then load sharing weights for the group are normalized, and a maximum message rate capacity threshold associated with each group member is used to determine whether the discarding of messages is required.

Methods and systems for providing enhanced network security for network management messages and subsystem management messages are disclosed. A network security function receives a network or subsystem management message from a first location in a network. The network security function determines whether one or more predetermined parameters in the network management message are not associated with the originating location. In response to determining that are not associated with the originating location, a network security action, such as discarding the message and / or notifying a network operator, is performed.

Methods and systems for WLAN-based signaling network monitoring are disclosed. A signaling message is received at a network routing node. A message copy function on the network routing node copies the signaling message. The message copy function forwards the copied signaling message to a WLAN interface. The WLAN interface transmits the signaling message to an external network monitoring platform via a wireless local area network connection.
