US Patent:

6765990, Jul 20, 2004

Filed:

Dec 19, 2002

Appl. No.:

10/325225

Inventors:

Steven Michael Freedman - Raleigh NC
Patrick Joseph Galizia - Cary NC
Richard James Spangler - Raleigh NC
Joseph Yu-Lung Wan - Richardson TX

Assignee:

Tekelec - Calabasas CA

International Classification:

H04M 322

US Classification:

379 3205, 379126, 379133

Abstract:

Database-driven methods and systems for database driven real time call tracing are disclosed. Signaling messages are copied from signaling link interface modules. The copied messages are sent to a database. A server located remotely from the database sends a query to the database for a real time call trace. The database is searched for messages that match the search criteria. If no messages are located in the historical data stored in the database, data entering the database is analyzed in real time.

Appl. No.:

10/154309

Inventors:

Yoogin Lean - Apex NC, US
David Wayne Minnich - Durham NC, US
Kevin Allen Sapp - Apex NC, US
Richard James Spangler - Raleigh NC, US

Assignee:

Tekelec - Morrisville NC

International Classification:

G06F 15/173
G06F 15/177

US Classification:

709224, 709220

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 () being monitored and a network monitoring server executing on a network monitoring processor (). 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.

Assignee:

Tekelec - Calabasas CA

International Classification:

H04M 124
H04M 1500
H04M 342
H04M 700

US Classification:

37911501

Abstract:

A system for collecting and processing SS7 message signaling units (MSUs) includes a network interface for copying MSUs from an SS7 signaling link or a TCP/IP signaling link. A call detail record generator communicates with the link interface to receive the copied MSUs and parse the MSUs to extract desired parameters from the MSUs. An application interface kit received commands from an application to control the flow of MSU parameters to the application in real time.
