Patent number: 9497082Abstract: Various exemplary embodiments relate to a method performed by a network policy node. The method may include: translating a policy into a plurality of rule objects, the policy including an applicability condition and one or more action rules; generating a selection rule table based on the applicability condition of one or more policies; generating an action rule table from the one or more action rules of an applicable policy, an action rule including an action condition and an action path; determining a set of applicable policies by evaluating the selection rule table using a rules engine; and selecting an action path by evaluating the action rule table using the rules engine. Various exemplary embodiments relate to a network policy node including a scanner that generates rules objects and rule tables based on one or more policies, a context information storage, and a rules engine that evaluates rule tables.Type: GrantFiled: October 3, 2011Date of Patent: November 15, 2016Assignee: Alcatel LucentInventors: Kevin Scott Cutler, Allen Robinson

Patent number: 9398168Abstract: Various exemplary embodiments relate to a method and related network node and machine-readable storage medium including a policy and charging rules node (PCRN) receiving a plurality of related service requests from different devices. The PCRN may establish a Session Binding Identifier (SBI) for each message received. The SBI may include one or more subscriber IDs. Upon receipt of a message, the PCRN may compare the included subscriber IDs against information included in a subscriber database to match with a specific subscriber profile. The PCRN may use the subscriber profile to determine whether existing established sessions are associated with the same subscriber profile, and may bind the sessions together when they are associated with a common subscriber profile.Type: GrantFiled: November 5, 2014Date of Patent: July 19, 2016Assignee: Alcatel LucentInventors: Kevin Scott Cutler, Felix Katz

Patent number: 9361581Abstract: A method of exchanging a rules engine decision tree cache is disclosed. The method provides for provision accepting a command to build a replacement rules engine decision tree cache, replacing the existing cache if the decision tree creation process is successful, retaining the existing cache if the decision tree creation process is not successful, and providing specific error messages in the event that the replacement fails. The method allows an network operator to change the rules for the rule engine without disruption of real-time service and allows for a level of error checking prior to provisioning the new decision tree.Type: GrantFiled: June 30, 2010Date of Patent: June 7, 2016Assignee: Alcatel LucentInventors: Kevin Scott Cutler, Katha Kulasingam, Felix Katz, Matthew Yee

Patent number: 8625612Abstract: Various embodiments relate to a system and related method for managing a connection of a user device to a communications network. Various embodiments relate to a Policy and Charging Rules Node (PCRN) receiving a user requests through multiple serving gateways. The PCRN may assign one of the serving gateways as a primary serving gateway when the serving gateway sends a Gateway Control Session that binds to an IP-CAN session established in the PCRN. When the PCRN receives a subsequent message from another serving gateway, the PCRN may reassign the new serving gateway as primary when its Gateway Control Session matches. The PCRN may then mark the former serving gateway as pending termination and signal the marked gateway to terminate. After sending rules to serving gateways not pending termination, the PCRN may delete those serving gateways marked for termination.Type: GrantFiled: June 29, 2010Date of Patent: January 7, 2014Assignee: Alcatel LucentInventors: Fernando Cuervo, Allen Robinson, Kevin Scott Cutler
