Introduction The ETSI TS 102 232 i.1 series of standards aims to provide a common delivery interface for lawfully-intercepted material from a wide range of services. The aim of the pres
23、ent document is to increase the range of services to which the ETSI TS 102 232 i.1 interface applies, by including services from 3GPP TS 33.108 3 and ANSI/J-STD-025-B 4 within the ETSI TS 102 232 i.1 delivery framework. ETSI ETSI TS 102 232-7 V3.5.1 (2018-04)6 1 Scope 1.0 Introduction The present do
24、cument specifies an approach for the handover of the lawfully-intercepted information that is defined in the two standards: 3GPP TS 33.108 3 and ANSI/J-STD-025-B 4. The present document uses the handover techniques defined in ETSI TS 102 232-1 2. In this way, the present document allows additional s
25、ervices to be delivered through a common interface. 1.1 UMTS/GPRS and EPS - 3GPP TS 33.108 The scope of the present document includes the handover of lawfully-intercepted information from the following parts of 3GPP TS 33.108 3: Intercept Related Information (IRI) and the Content of Communication (C
26、C) from the mobile circuit-switched domain (3GPP TS 33.108 3, clause 5). IRI and CC from the mobile packet-switched domain (3GPP TS 33.108 3, clause 6). IRI and CC from the multi-media domain (3GPP TS 33.108 3, clause 7). IRI and CC from the EPS domain (3GPP TS 33.108 3, clause 10). IRI and CC from
27、the IMS Conference domain (3GPP TS 33.108 3, clause 11). IRI and CC from the IMS-based VoIP domain (3GPP TS 33.108 3, clause 12). IRI from the Proximity Services domain (3GPP TS 33.108 3, clause 13). IRI and CC from the Group Communication System Enablers domain (3GPP TS 33.108 3, clause 14). The pr
28、esent document does not override or supersede any specifications or requirements in 3GPP TS 33.108 3. 1.2 CDMA2000 - ANSI/J-STD-025-B The scope of the present document includes the handover of lawfully-intercepted information from the following parts of ANSI/J-STD-025-B 4: Call identifying informati
29、on from the mobile circuit-switched domain (ANSI/J-STD-025-B 4, clause 5.4). Call Content (CC) from the mobile circuit-switched domain is not covered by the present document. Communication identifying information (CII) and CC from the mobile packet-switched domain (ANSI/J-STD-025-B 4, clause 5.5). T

CC from packet switched services are sent using the uMTSCC element CCContents, which is an OCTET STRING. Alternatively, subject to national agreement, CC from packet switched services are sent using the uMTS
