Introduction The ETSI TS 102 232 i.1 series of standards aims to provide a common de
21、livery interface for lawfully-intercepted material from a wide range of services. The aim of the present 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
22、 delivery framework. ETSI ETSI TS 102 232-7 V3.3.1 (2016-03)6 1 Scope 1.0 Introduction The present document 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 hand
23、over techniques defined in ETSI TS 102 232-1 2. In this way, the present document allows additional services 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 followi
24、ng parts of 3GPP TS 33.108 3: Intercept Related Information (IRI) from the mobile circuit-switched domain (3GPP TS 33.108 3, clause 5). Content of Communication (CC) from the mobile circuit-switched domain is not covered by the present document. IRI and CC from the mobile packet-switched domain (3GP
25、P 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 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
26、). 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 present document does not override or supersede any specifications or requirements in 3GPP TS 33.108 3. 1.2 CDMA2000 - ANSI/J-STD
27、-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 information from the mobile circuit-switched domain (ANSI/J-STD-025-B 4, clause 5.4). Call Content (CC) from the mobile circuit-switched
28、 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). The present document does not override or supersede any specifications or requirements in ANSI/J-STD-025-B 4. 2 References 2.1 N

44、cific component of the ETSI TS 102 232-1 2 framework. 3GPP TS 33.108 3 and ANSI/J-STD-025-B 4 define the interception behaviour that leads to IRI, Communication-Identifying Information (CII) or call-identifying information events on the handover interface, for both the packet data domain and circuit
45、 switched domain. 4.2 Reference model Figure 1: Reference model 5 GPRS/UMTS Headers, data exchange and networks 5.1 Approach ETSI TS 102 232-1 2 describes a technique for data exchange, and specifies the headers that shall be associated with the results of interception.

46、ETSI TS 102 232-1 2 regarding headers, data exchange and networks demonstrates how the header fields in ETSI TS 102 232-1 2 can be populated in a direct and straightforward manner using the interception information available in 3GPP TS 33.108 3. 5.2 Structures IRI events from 3GPP TS 33.108 3, for b
