scope:
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 TISPAN NGN R1.
The present document specifies the stage 1 and stage 2 model for Lawful Interception (LI) of TISPAN NGN services as specified by TR 180 001 [5] and covering the following services explicitly:
- PSTN/ISDN emulation services (non IMS); and
- IMS based services.
The provisions in the present document apply only when the target of interception is an NGN user identified as specified in TS 184 002 [6], and when the network supplying services on behalf of the CSP is an NGN as specified by TISPAN in TR 180 001 [5] and ES 282 001 [1].
A guide to the application of the handover specifications is given in informative annexes.
NOTE: Handover aspects are not specified in the present document but are described in TS 133 108 [8], ES 201 671 [2] and TS 102 232 [4].
