  • Patent number: 9241202
    Abstract: Methods, systems, and computer readable media for dynamically and conditionally setting service triggers in a communications network are disclosed. According to one aspect, a system for dynamic and conditional trigger insertion includes a dynamic trigger insertion (DTI) rules database for maintaining conditions or rules for dynamic trigger insertion and a DTI screening module for receiving a first mobility management message that is associated with a mobile subscriber, using the DTI rules database to determine whether a condition or rule for dynamic trigger insertion is satisfied, and, in response to determining that a condition or rule for dynamic trigger insertion is satisfied, generating a second mobility management message that includes a dynamically inserted trigger condition.

  • Patent number: 8831016
    Abstract: Methods, systems, and computer readable media for configurable Diameter address resolution are disclosed. One method includes, at a Diameter signaling router (DSR), sending Diameter signaling messages to and receiving Diameter signaling messages from Diameter signaling entities in a network. The method further includes providing for configuration of a plurality of routing entity identities and an order for preferentially using the routing entity identities in performing Diameter address resolution. The method further includes routing Diameter signaling messages using Diameter address information determined in the Diameter routing address resolution.

  • Patent number: 8737304
    Abstract: Methods, systems, and computer readable media for hybrid session based Diameter routing are disclosed. According to one method, the method comprises receiving, at a first Diameter signaling router (DSR), a first Diameter message for processing by a Diameter server. The method also includes selecting, using a Diameter node selection algorithm that operates on at least one parameter in the first Diameter message without requiring use of stored Diameter binding information, a first Diameter server to which the first Diameter message is to be routed. The method further includes determining whether the first Diameter server is available. The method also includes, in response to determining that the first Diameter server is not available, selecting a second Diameter server to which the first Diameter message is to be routed and creating an exception binding record that associates the second Diameter server and information in the first Diameter message.

  • Patent number: 6324396
    Abstract: A system, method, and apparatus are provided for sending a calling party number for a roaming mobile station to a called party. The roaming mobile station subscriber dials an abbreviated number, corresponding to a full directory phone number, which is received by a visited public land mobile network (V-PLMN) . The V-PLMN queries a service control point (SCP) to determine routing instructions corresponding to the abbreviated number. During the query, the SCP stores the calling party number in a register. The SCP transmits the routing instructions appended with an index and an identification number for the SCP. The V-PLMN uses the route instructions to route the call generated by the mobile station to a switching point serving the called party. The switching point then uses the index to retrieve the stored called party number from the SCP.
