ETSI TS 103 221-1

ETSI TS 103 221-1 defines an electronic interface for the exchange of information relating to the establishment andmanagement of Lawful Interception. Typically, this interface would be used between a central LI administrationfunction and the network internal interception points.

Typical reference models for LI define an interface between law enforcement agencies (LEAs) and communicationservice providers (CSPs), called the handover interface. They also define an internal network interface within the CSPdomain between administration and mediation functions for lawful interception and network internal functions, whichfacilitates 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 ofcommunication (X3). The present document specifies the administration interface X1.
