1 TC LI ETSI Technical Committee Lawful Interception ETSI/TC LI Peter van der Arend (Royal KPN) Chairman ETSI/TC LI
2 Why LI The providers of public telecommunications networks and services are legally required to make available to the authorities the information necessary to enable them to investigate telecommunications.
3 History ETSI/TC Security Techniques Advisory Group (STAG) (1991) ETSI/TC Security (TC SEC) –Working Group Lawful Interception (SEC-WGLI) (1997) ETSI/TC Lawful Interception (TC LI) (Oct 2002)
4 Terms of Reference To develop a suite of standards that allow ETSI standards to support industry compliance to the requirements of national and international law. To capture the requirements of “Law Enforcement Agencies” and translating those into requirements to be applied to technical specifications. To develop and publish handover interfaces, and of rules for the carriage of technology specific interception across these interfaces.
5 Relationships inside ETSI 3GPP (SA3-LI) (LI for UMTS) TC AT (LI for IP Cablecom) TC SPAN & EP TIPHON ---> TISPAN PLT (LI for Powerline Communications) EP TETRA TC MTS
6 Relationships outside ETSI National and Regional Law Enforcement Agencies OASIS (TC LegalXML-LI) T1S1 LAES AHG ANSI
7 Participation in TC LI Law Enforcement Agencies –NL, UK, DE, AS, USA, IT, CA, FR, FIN, RU Operators –KPN, BT, DT, Telia, Inmarsat, T-Mobile, Vodafone, Telenor, Telstra Manufacturers (switch) –Nokia, Siemens, Ericsson, Alcatel, Cisco, Marconi, Nortel, Lucent Technologies Manufacturers (mediator / LEA equipement) –Aqsacom, ETI, VeriSign, TopLayer, GTEN, Verint, Pine, Nice
8 LEA requirements LEATS 101 331: Requirements of Law Enforcement Agencies –Provides guidance in the area of co-operation by network operators/service providers with the lawful interception of telecommunications. –Provides a set of requirements relating to handover interfaces for the interception.
9 Other specifications ES 201 158 Requirements for Network Functions ES 201 671 / TS 101 671 Handover Interface for the Lawful Interception of Telecommunications Traffic TR 102 053 Notes on ISDN LI functionalities TR 101 943 Concepts of Interception in a Generic Network Architecture.
