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 present document is to increase the range of services to which
the ETSI TS 102 232 [i.1] interface applies, by including services from ETSI TS 133 108 [3], ETSI TS 133 128 [6] and
ANSI/J-STD-025-B [4] within the ETSI TS 102 232 [i.1] delivery framework.

1 Scope
Introduction
The present document specifies an approach for the handover of the lawfully-intercepted information that is defined in
the three standards: ETSI TS 133 108 [3], ETSI TS 133 128 [6] 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 services
to be delivered through a common interface.
UMTS/GPRS and EPS - ETSI TS 133 108
The scope of the present document includes the handover of lawfully-intercepted information from the following parts
of ETSI TS 133 108 [3]:
• Intercept Related Information (IRI) and the Content of Communication (CC) from the mobile circuit-switched
domain (ETSI TS 133 108 [3], clause 5).
• IRI and CC from the mobile packet-switched domain (ETSI TS 133 108 [3], clause 6).
• IRI and CC from the multi-media domain (ETSI TS 133 108 [3], clause 7).
• IRI and CC from the EPS domain (ETSI TS 133 108 [3], clause 10).
• IRI and CC from the IMS Conference domain (ETSI TS 133 108 [3], clause 11).
• IRI and CC from the IMS-based VoIP domain (ETSI TS 133 108 [3], clause 12).
• IRI from the Proximity Services domain (ETSI TS 133 108 [3], clause 13).
• IRI and CC from the Group Communication System Enablers domain (ETSI TS 133 108 [3], clause 14).
The present document does not override or supersede any specifications or requirements in ETSI TS 133 108 [3].
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 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 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].
ETSI TS 133 128
The scope of the present document includes the handover of lawfully-intercepted information in accordance with ETSI
TS 133 128 [6]

4 General
4.1 Approach
The present document forms part 7 of the ETSI TS 102 232 [i.1] family of standards, in that it is a service-specific
component of the ETSI TS 102 232-1 [2] framework.
ETSI TS 133 108 [3], ETSI TS 133 128 [6] 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
