Routable Packet Structure for Lawful Intercept Traffic Analysis

The patent introduces an authentication device as an intermediary that centralizes the control of lawful intercept functionality. Instead of managing intercept settings at each individual network device through command line interfaces, the authentication device acts as a mediator that receives intercept requests and automatically configures the appropriate network devices. This reduces management complexity by consolidating control in a single location while maintaining the ability to intercept traffic across multiple services and devices.

The patent implements packet encapsulation where the original mirrored data packet streams are nested inside a standardized outer packet structure. The inner packet contains the actual mirrored traffic data, while the outer packet includes standardized routing headers and control information that comply with standard routing protocols. This nested structure allows the mirrored traffic to be transported across different network types using conventional routing infrastructure without requiring modifications to the underlying packet format or routing behavior.

The patent transforms the static traffic monitoring approach into a dynamic system by integrating lawful intercept functionality with the authentication process. When a mobile user logs in at any location, the authentication device dynamically determines which network devices are handling that user's traffic and automatically configures intercept settings accordingly. This dynamic adaptation allows the system to follow mobile users to any login location without requiring manual reconfiguration or prediction of user behavior patterns.
