Lawful Interception Software for the Complete LI Chain
Modular, scalable platforms for operators, ISPs and agencies. Manage warrants, mediate intercepted traffic, hand it over securely and receive it in a monitoring facility.
Lawful interception software is the set of applications that manages interception orders, extracts target traffic from the network and delivers it to authorized agencies. ICS provides modular platforms for this chain, from warrant management to secure handover and reception at the agency.
Key facts
- Three core components: LIMS, LI Mediation Platform and ICS LEMF.
- Service modules: messaging, IP, VoIP and OTT, reusing shared provisioning, logging and handover.
- Networks: fixed, mobile, VoIP, broadband and OTT services.
- Deployment: dedicated hardware, virtualized environments or private cloud.
- Standards: ETSI and 3GPP handover and internal interfaces.
What does lawful interception software do?
Operators, ISPs and service providers must intercept communications when a court or authority orders it. They must also disclose certain data on request. Our lawful interception software turns these obligations into controlled, auditable workflows.
The platforms are modular and scale with the network. Service-specific modules for messaging, IP, VoIP and OTT reuse the same provisioning, logging and handover functions. New services therefore do not require a separate LI stack.
Core components of ICS lawful interception software
01
LIMS
The Lawful Interception Management System centralizes warrant intake, target provisioning and audit across all networks. It controls network elements and mediation devices. Learn more
02
LI Mediation Platform
Collects intercepted content and metadata from multi-vendor networks, filters it by active warrant and converts it to national and international handover formats. Learn more
03
ICS LEMF
The receiving side. A law enforcement monitoring facility for agencies, and a Test LEMF that lets operators verify their own delivery. Learn more
How does the LI chain work?
The three components form one chain. Each step uses standardized interfaces.
1
Warrant management (LIMS)
The LIMS receives the order, checks it and provisions the target via X1.
2
Mediation
Network elements deliver target traffic via X2/X3. The mediation platform filters and formats it.
3
Handover
IRI travels via HI2 and content of communication via HI3 to each authorized agency, strictly separated.
4
Reception (LEMF)
The monitoring facility receives, decodes and stores the data for analysis.
Component overview
| Component | Role | Side | Key interfaces |
|---|---|---|---|
| LIMS | Warrant management, target provisioning, audit | Operator | X1 (ETSI TS 103 221-1), HI1 (ETSI TS 103 120) |
| LI Mediation Platform | Collection, filtering, formatting and delivery | Operator | X2/X3 (ETSI TS 103 221-2), HI2/HI3 (ETSI TS 102 232, TS 101 671, 3GPP TS 33.108/33.128) |
| ICS LEMF | Reception, decoding, analysis, evidence handling | Agency (Test LEMF: operator) | HI1, HI2/HI3, inter-LEMF handover (ETSI TS 103 462) |

Frequently Asked Questions
What is lawful interception software?
Lawful interception software manages and executes legal interception orders in a communications network. It covers warrant handling, target provisioning, collection and formatting of intercepted traffic, and handover to agencies. On the agency side, a monitoring facility receives and analyzes the data. ICS offers all three parts as modular components: LIMS, LI Mediation Platform and ICS LEMF.
Do I need all three components?
No. Operators typically need a LIMS and a mediation platform, while agencies need a LEMF. Operators may also use the Test LEMF edition of ICS LEMF to check their HI2/HI3 delivery. Each component uses standardized interfaces, so it can work with products from other vendors. Many operators still choose one supplier to reduce integration effort.
Which networks and services are supported?
The platforms support fixed, mobile, VoIP, broadband and OTT services. Service modules for messaging, IP, VoIP and OTT reuse common provisioning, logging and handover functions. This makes it easier to add new services later. Supported standards include the ETSI handover specifications and the 3GPP LI specifications for 4G, IMS and 5G.
Can the software run in a virtualized environment?
Yes. ICS lawful interception software can run on dedicated hardware, in virtualized environments or in a private cloud. The choice depends on your security requirements, existing infrastructure and national rules. Our engineers plan the deployment together with you and prepare it for acceptance testing by the authorities, for example by the BNetzA in Germany.
How does the software integrate with existing systems?
APIs connect the platforms to network operations centers, OSS/BSS and ticketing systems. Towards the network, the LIMS and mediation platform use X1/X2/X3 interfaces. Towards agencies, they use HI1/HI2/HI3. This standards-based approach reduces custom development and keeps the LI chain maintainable when network vendors change.
