Lawful Interception (LI); Internal Network Interfaces; Part 1: X1

scope:

The present document defines an electronic interface for the exchange of information relating to the establishment and management of Lawful Interception. Typically, this interface would be used between a central LI administration function and the network internal interception points.

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 and 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 the administration interface X1.
