Keysight Lawful Intercept Solution Saves Customer €1 Million per Year

When it comes to regulatory compliance, you can’t afford not to have complete network visibility. You need to know what is, and what is not, happening on your network at any given time. A large wireless voice and data carrier with 15 million subscribers worldwide had this exact problem they had blind spots that they knew were causing problems but couldn’t see a solution.

The wireless communications carrier needed a solution to address the following four pain points:

• Identify calls that were bypassing the Lawful Intercept Mirror IMS State Function (LMISF) network functionality.
• Correlate the signaling and data streams for those calls for packet capture file (PCAP) creation.
• Analyze the information to determine if the scenario was created by a malicious entity or if it was some sort of misconfiguration error.
• Finally, mitigate the problem by either fixing the configuration error or sending the malicious information to the legally authorized enforcement agency.
