Foreword This Technical Specification (TS) has been produced by ETSI

21、Technical Committee Telecommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN). Introduction The NGN is required to operate within a regulated environment and to comply to the privacy directive EC/2002/58 i.1 which identifies in articles 5(2), and 15(1) the fra

22、mework and obligation for CSPs to provide facilities for Lawful Interception and Data Retention. These obligations are further extended by the European Union Council Resolution COM 96/C329/01 15 along with the International User Requirement (IUR) 16, stating the obligations on member states to provi

23、de facilities for LI. These documents and the requirements in them are respected in a balanced way in the present document. ETSI ETSI TS 187 005 V3.1.1 (2012-06)61 Scope The present document specifies the stage 2 model for Lawful Interception (LI) of TISPAN NGN services as specified by TR 180 001 i.

24、3. The requirement for provision of lawful interception for all Communication Service Providers (CSP) is described in TS 101 331 3 and the present document gives the stage 1 and stage 2 definition for provision of an interception capability in for the NGN as specified by TISPAN. The provisions in th

25、e present document apply only when the target of interception is an NGN user identified as specified in TS 184 002 7, and when the network supplying services on behalf of the CSP is an NGN as specified by TISPAN in TR 180 001 i.3 and where the NGN architecture is as specified in ES 282 001 1. The pr

26、esent document takes account of the requirement to support dynamic triggering of interception. A guide to the application of the handover specifications is given in informative annexes. NOTE 1: Handover aspects are not specified in the present document but are described in TS 133 108 9, TS 101 671 2

27、 and TS 102 232-1 4, TS 102 232-5 5, and TS 102 232-6 6. NOTE 2: The present document assumes that the LEA/LEMF receiving intercept related information records from the NGN is able to decode NGN signalling streams and thus there is no definition in the present document of how to present NGN data in

28、non-NGN formats. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific. For specific references, only the cited version applies. For non-specific references, the latest version of the reference document (including any
