  • Patent number: 9379965
    Abstract: Methods, systems, and computer program products for managing and selectively distributing routing information in a routing node are disclosed. In one implementation, a method for selectively distributing routing information in a routing node includes organizing internal signaling resources are organized so as to facilitate the efficient mapping of signaling system 7 (SS7) message transfer part (MTP) signaling protocol attributes to Internet protocol (IP)-based signaling resources. A routing status information sharing hierarchy is defined, which enables routing status information to be efficiently shared among members of a signaling mateset group. Members of a signaling mateset replicate and distribute SS7 MTP network management information across non-MTP signaling connections, such as IP connections.

  • Patent number: 9148388
    Abstract: Methods, systems, and computer readable media for performing enhanced service routing are disclosed. One method includes receiving, at a Diameter application executing on a message processor associated with a DSR, a Diameter message that requires a service. The method also includes determining, using service routing data, at least one service provider for performing the service associated with the Diameter message, wherein the service routing data is based on service capability information provided by a plurality of service providers and sending the Diameter message or a portion of the Diameter message to the at least one service provider for performing the service.

  • Patent number: 9106769
    Abstract: According to one aspect, the subject matter described herein includes a method for congestion management in a Diameter signaling network. The method occurs a Diameter routing node. The method includes determining, using a metric associated with Diameter message processing, that a first Diameter message processing metric threshold has been exceeded. The method also includes in response to determining that the first Diameter message processing metric threshold has been exceeded, performing a first congestion mitigation action, where performing the first congestion mitigation action includes analyzing subsequent Diameter messages to determine one or more common attributes of the subsequent Diameter messages and in response to determining the one or more common attributes of the subsequent Diameter messages, performing a second congestion mitigation action for Diameter messages having the one or more common attributes.

  • Patent number: 9001990
    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.

  • Patent number: 8224928
    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.
