  • Patent number: 7743131
    Abstract: Disclosed is a communications network element that is capable of routing signaling messages and also performing inter-network management functions in a converged telephony-data network environment. A signaling gateway routing node is adapted to facilitate signaling communication between nodes in a signaling system 7 network and nodes in an Internet protocol (IP) type network. In addition to basic message routing functionality, the signaling gateway routing node is adapted to notify nodes in the IP network when a node in the SS7 network becomes congested or unavailable. In certain cases, the signaling gateway selectively notifies only IP nodes that are concerned with the status of the troubled SS7 node, while in other cases, notification messages are broadcast to all relevant IP nodes. The signaling gateway also serves to filter redundant congestion status queries or polling type messages that are conveyed from IP nodes through to the distressed SS7 node.

  • Patent number: 7738648
    Abstract: Methods, systems, and computer program products for rerouting signaling message traffic in response to unavailability of one or more services are disclosed. According to one method, service signaling message traffic is received at a signaling message routing node that provides a plurality of different services. It is determined whether at least one of the services is unavailable. In response to determining that at least one of the services is unavailable, the signaling message traffic for the unavailable service is rerouted to an alternate destination. Signaling message traffic for the remaining services is received and processed.

  • Patent number: 7720463
    Abstract: The subject matter described herein includes methods, systems, and computer program products for providing third party control of access to media content available via broadcast and multicast service (BCMCS). According to one method, control of access to streaming media content to a subscriber terminal via a BCMCS may be implemented at a network element, such as an authentication, authorization and accounting (AAA) server or a BCMCS controller. The method may include receiving a message associated with a request for access to streaming media content by a requesting mobile subscriber. Mobile subscriber identification and requested content identification information are determined from the message. The mobile subscriber identification is used to identify a content viewing rule for the requesting mobile subscriber. The content identification is used to determine whether allowing the subscriber to view the content would violate the content viewing rule.

  • Patent number: 7693066
    Abstract: Methods, systems, and computer program products for reducing the likelihood of signaling link congestion on a failing or recovering signaling linkset are disclosed. According to one aspect, a method for reducing or eliminating congestion on a recovered link in a previously failed linkset due to the routing of post-global title (GT) translated signaling message traffic is disclosed. When the first link in a previously failed linkset becomes available, routes associated with the recovering linkset are marked as restricted. GT translated messages are directed to the lowest cost route that is marked as allowed. If no routes are marked as allowed, messages are directed to the lowest cost route that is marked as restricted. When a predetermined number or percentage of the links in a linkset become available, routes associated with the recovering linkset are marked as allowed.

  • Patent number: 7680928
    Abstract: An automatically configurable network monitoring system includes a network monitoring communications protocol used for communications between a network monitoring client executing on a routing node (100) being monitored and a network monitoring server executing on a network monitoring processor (106). According to the network monitoring communications protocol, the network monitoring client broadcasts a network monitoring service request message to the network monitoring servers. The service request message identifies a signaling link for which network monitoring service is being requested. The network monitoring servers provisioned to the requested provide network monitoring service respond affirmatively and thereby automatically grant network monitoring service. The network monitoring system may be completely probeless or, alternatively, used in conjunction with probe-based network monitoring devices.

  • Patent number: 7650367
    Abstract: Methods, systems, and computer program products for detecting and restoring missing or corrupted data in a distributed, scalable, redundant measurement platform database are disclosed. According to one method, a local database including local database entries is audited to identify suspect local database entries having at least one of missing and corrupted data. The local database is cross-compared with a redundant remote database that is a peer of the local database and that includes redundant remote database entries that are associated with the local database entries to identify local database entries that are inconsistent with the redundant remote database entries. For each local database entry identified as suspect and inconsistent with the corresponding redundant remote database entry, the local database entry is replaced with the redundant remote database entry.

  • Patent number: 7633969
    Abstract: 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.

  • Patent number: 7631093
    Abstract: A scalable, reliable session initiation protocol (SIP) signaling router includes cluster nodes for performing SIP services. A location server replicates its database of SIP location information to each of the cluster nodes. Because each cluster node maintains its own local copy of the SIP location database, the time for routing SIP signaling messages is decreased. Load sharing is also performed among the cluster nodes by Ethernet switches that connect the cluster nodes to external networks. One Ethernet switch periodically sends messages to each of the cluster nodes to monitor the operational status of the cluster nodes. The Ethernet switch also maintains a connection tuple table containing information regarding active connections to each of the cluster nodes. Load sharing is performed based on the operational status and the connection tuple table.
