Introduction The ETSI TS 102 232 i.1 series of standards aims to provide a common delivery inter
21、face 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 delivery fr
22、amework. ETSI ETSI TS 102 232-7 V3.4.1 (2017-03)61 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 handover techniqu
23、es 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 following parts of 3
24、GPP 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 (3GPP TS 33.108 3
25、, 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). IRI from t
26、he 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-025-B The sc
27、ope 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 domain is no
28、t 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).

44、f 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 switched domain.

46、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. The present document follows ETSI TS 102 232-1 2 regarding headers, data exchange and networks demonstrates how the header fields in ETSI TS 102
47、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 both circuit and packet switched services, are sent using the uMTSIRI element of IRIContents. CC from packet switched
48、 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 uMTSCC-CC-PDU element of CCContents, which is the CC-PDU from 3GPP TS 33.108 3, containing the uLIC-header and payload.
49、6 GPRS/UMTS Intercept Related Information (IRI) and Content of Communication (CC) 6.1 Definition of IRI events and CC IRI events are defined as per 3GPP TS 33.108 3. 6.2 IRI format IRI events are defined as per 3GPP TS 33.108 3 for both circuit and packet switched services. They are sent using the uMTSIRI element of IRIContents. Fields which are duplicated in the 3GPP TS 33.108 3 and ETSI TS 102 232-1 2 structures should be populated consistently in both struc
