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 (CC) 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).

Overview
SIST-TS ETSI/TS 102 232-7 V3.13.1:2023 addresses the requirements for lawful interception (LI) in mobile services, focusing on the handover interface and service-specific details for IP-based delivery. This standard is part of a multi-part series developed by ETSI Technical Committee Lawful Interception (LI) and adopted as SIST-TS by the Slovenian Institute for Standardization (SIST). It is specifically aligned with the frameworks established by 3GPP TS 33.108 and 3GPP TS 33.128, facilitating the secure and standardized delivery of intercepted data from various mobile service domains to authorized law enforcement agencies.
The document outlines how intercepted information, such as Intercept Related Information (IRI) and Content of Communication (CC), must be formatted and transferred across interfaces to support a broad range of mobile and IP-based communication services. By providing service-specific guidance, this standard ensures the seamless integration of mobile service interception capabilities into an operator's existing lawful interception delivery mechanisms.
Key Topics
Lawful Interception for Mobile Services
Defines the requirements for intercepting communications in mobile networks according to referenced 3GPP standards.Handover Interface Specification
Utilizes ETSI TS 102 232-1 as the baseline, describing how headers and data exchange should be structured for efficient and reliable transfer of intercepted data.Service-Specific Data Models
Details the mapping and handling of IRI and CC for:- Circuit-switched and packet-switched mobile domains
- Evolved Packet System (EPS), IMS Conference, IMS-based VoIP
- Multimedia, proximity services, and group communication systems
Data Consistency and Mapping
Provides guidance on consistent population of data fields and header elements when transferring information from network operator systems to law enforcement monitoring facilities.Alignment with 3GPP and ETSI Frameworks
Ensures compatibility and compliance with the latest regulatory and technical requirements for lawful interception in both 4G and 5G environments.
Applications
Telecommunications Operators
Enables CSPs and mobile network operators to meet legal obligations for lawful interception by delivering intercepted mobile communications in a standardized format.Law Enforcement Agencies
Supports efficient, accurate, and secure access to both communication content and metadata, essential for criminal investigations and national security operations.System Integrators and Solution Providers
Facilitates the integration of interception solutions within multi-vendor and multi-technology environments by leveraging a common interface and service-specific data structures.Regulatory Compliance
Assures national and regional telecom regulatory authorities that interception practices adhere to internationally recognized standards, reducing risk and complexity in audit and enforcement.

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 3GPP TS 33.108 [3] and 3GPP TS 33.128 [6]
within the ETSI TS 102 232 [i.1] delivery framework.

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 3GPP TS 33.108 [3] and 3GPP TS 33.128 [6]
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 two standards: 3GPP TS 33.108 [3] and 3GPP TS 33.128 [6]. 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.
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 (CC) 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 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 present document does not override or supersede any specifications or requirements in 3GPP TS 33.108 [3].
3GPP TS 33.128
The scope of the present document includes the handover of lawfully-intercepted information in accordance with 3GPP
TS 33.128 [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.
3GPP TS 33.108 [3] and 3GPP TS 33.128 [6] define the interception behaviour that leads to IRI events on the handover
interface, for both the packet data domain and circuit switched domain.
