  1. ETSI Technical CommitteeLawful InterceptionETSI/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 TechniquesAdvisory 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 • TS 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 671Handover 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. • TR 101 944 Issues on IP Interception.

  13. Actual working issues • DTR 00014: Lawful Interception of public Wireless LAN Internet Access • General update of:TR 101 943 Concepts of Interception in a Generic Network Architecture • Keeping up to date of the LI specifications

  14. LI standards in 3GPP (UMTS) • TS 133 106Lawful interception requirements • TS 133 107Lawful interception architecture and functions • TS 133 108Handover interface for Lawful Interception

  15. Future developments • Lawful Interception of IP Cablecom • Lawful Interception of TIPHON • Lawful Interception of third generation mobile systems • Maintenance of existing documents; especiallyES 201 671 / TS 101 671 and TS 101 331.
