Patent number: 8755499Abstract: Methods, computer program products, and systems for managing VoIP network elements are provided. Methods include receiving call details records (CDRs) from a plurality of network elements. The received CDRs including disconnect cause codes and telephone call correlation identifiers. The received CDRs are correlated to telephone calls based on the telephone call correlation identifiers. Two CDR records are associated with the same telephone call when their telephone call correlation identifiers are the same. A master correlated CDR is created for each telephone call. The creating includes assigning a correlated disconnect cause code and classifying the telephone call. The assigning and classifying are responsive to the received CDRs associated with the telephone call. The master correlated CDR includes the correlated disconnect cause code and the telephone call classification. A threshold crossing alert (TCA) is generated in response to a threshold for the correlated disconnect cause code being reached.Type: GrantFiled: August 28, 2012Date of Patent: June 17, 2014Assignee: AT&T Intellectual Propert I, L.P.Inventors: Yu-Lein Kung, Jeffrey Stein

Patent number: 8634527Abstract: A method and apparatus that employ the use of CDRs to effectively monitor and proactively respond to network or service events that impact performance within a network are disclosed. For example, the method receives a plurality of call detail records (CDRs), wherein each of the plurality of call detail records comprises a plurality of fields. The method determines a n-field rule signature from each of the call detail records (CDRs), and analyzes the n-field rule signatures from the plurality of call detail records (CDRs) for detecting at least one network performance problem.Type: GrantFiled: June 10, 2008Date of Patent: January 21, 2014Assignee: AT&T Intellectual Property I, L.P.Inventors: Li-Jin Chung, Richard Farel, Yu-Lein Kung, Alek Remash, James A.

Patent number: 8576724Abstract: Special service impacting events in an IP network are collected and correlated. Real-time data representing occurrence of trunk group events impacting special services in trunk groups that are in service is collected, along with call detail records recorded by network elements representing occurrence of call events impacting special services and performance measurements of network elements representing occurrence of events affecting performance of the network elements impacting the special services. The collected real-time data representing occurrence of trunk group events, collected call detail record and collected performance measurements are correlated, and alarms are generated based on the correlated data.Type: GrantFiled: November 24, 2009Date of Patent: November 5, 2013Assignee: AT&T Intellectual Property I, L.P.Inventors: Yu-Lein Kung, Jeffrey Stein
