Lawful Interception (LI); Internal Network Interfaces; Part 2: X2/X3

scope:

The present document defines an electronic interface for the transmission of intercepted information as part of Lawful Interception. This interface is used from points of interception to LI mediation functions.

Typical reference models for LI define an interface between Law Enforcement Agencies (LEAs) and Communication Service Providers (CSPs), called the handover interface. They also define an internal network interface within the CSP domain between administration/mediation functions for lawful interception and network internal functions, which facilitates the interception of communication. This internal network interface typically consists of three sub-interfaces; administration (called X1), transmission of intercept related information (X2) and transmission of content of communication (X3). The present document specifies a protocol for delivering X2 and X3.
