LAWFUL INTERCEPTION
Chairman:
Peter van der Arend

|
Overview
Lawful interception plays a crucial role in helping law
enforcement agencies to combat criminal activity. Lawful interception of public
telecommunications systems in each country is based on national legislation in that
country. The purpose of standardization of lawful interception in ETSI is to facilitate
the economic realization of lawful interception that complies with the national and
international conventions and legislation. The Technical
Committee on Lawful Interception (TC LI) is the leading body for
lawful interception standardization within ETSI. Lawful interception standards have also been developed by ETSI
technical bodies AT,
TISPAN (SPAN
and TIPHON™), TETRA,
and by 3GPP™
(/SMG).
