The information pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found in ETSI SR 000 314: “Intellectual
40、 Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in respect of ETSI standards“, which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web server (http:/webapp.etsi.org/IPR/home.asp). Pursuant to the ETSI IPR Policy, no investigation
41、, including IPR searches, has been carried out by ETSI. No guarantee can be given as to the existence of other IPRs not referenced in ETSI SR 000 314 (or the updates on the ETSI Web server) which are, or may be, or may become, essential to the present document. Foreword This ETSI Standard (ES) has b
42、een produced by ETSI Technical Committee Lawful Interception (LI). Introduction References within the main body of the present document are made if applicable to the 3GPP specification number with in square brackets the reference number as listed in clause 2. In clause 2 “References“ the correspondi
43、ng ETSI specification number is indicated with a reference to the 3GPP specification number. 3GPP specifications are available faster than the equivalent ETSI specifications. ETSI ETSI ES 201 671 V3.1.1 (2007-05) 9 1 Scope The present document is step 3 of a three-step approach to describe a generic
44、 Handover Interface (HI) for the provision of lawful interception from a Network Operator, an Access Provider or a Service Provider (NWO/AP/SvP) to the Law Enforcement Agencies (LEAs). The provision of lawful interception is a requirement of national law, which is usually mandatory for the operation
45、 of any telecommunication service. Step 1 contains the requirements for lawful interception from a users (LEAs) point of view and is published in TS 101 331 1. Step 2 describes the derived network functions and the general architecture (or functional model) and is published in ES 201 158 2. The pres
46、ent document specifies: the generic flow of information as well as the procedures and information elements, which are applicable to any future telecommunication network or service; the network/service specific protocols relating to the provision of lawful interception at the Handover Interface (HI),
47、 for the following networks/services: - switched circuit; and - packet data. The technologies covered in the present document are: GSM, TETRA, GPRS, ISDN, PSTN, fixed NGN (including PSTN/ISDN emulation) and fixed IMS PSTN simulation. NOTE: As new networks and/or services are developed, the present d
48、ocument will be expanded as the relevant standards become available. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. References are either specific (identified by date of publication and/or edition number o
49、r version number) or non-specific. For a specific reference, subsequent revisions do not apply. For a non-specific reference, the latest version applies.
