The LIMA platform
One modular suite for the whole compliance chain
LIMA covers lawful interception, data retention and preservation, network availability, location services, and cell-tower change management — as modules that deploy independently and interoperate as one platform. Developed by our counterpart Group 2000; delivered, integrated, and supported across the Americas by G2K Labs.
The modules
Each module stands alone; together they cover a carrier's obligations end to end. All are vendor-agnostic and integrate with existing network equipment — with the intercept core supporting every generation through 5G.
LIMA Lawful Intercept
The interception core: warrant administration, mediation, and delivery to law-enforcement monitoring facilities in standardized handover formats.
- ADMF management console for warrant and target administration
- MDF2/MDF3 mediation and delivery — up to 23 Gbps sustained throughput per instance
- All technologies and services, including 5G, VoLTE (with S8HR inbound-roaming interception), and Narrowband-IoT
- Multi-LEA / multi-CSP: isolated, compliant workflows per agency and provider on one platform
- Handover per ETSI, 3GPP, and ATIS/J-STD-025-B (CALEA) standards; deployed in more than 40 countries
LIMA Data Retention & Data Preservation
Two complementary answers to legal disclosure obligations: Data Retention stores communication metadata network-wide for the mandated period; Data Preservation captures data for specific subjects or cases at law-enforcement request. Both are controlled by LIMA Disclosure Management, a module of the LIMA Management System.
- Highly scalable, fault-tolerant data store with flexible collection and transformation
- Workflow management for disclosure requests, with fast query and compliant handover to authorized entities
- Retained-data handover per ETSI TS 102 657; optional standards-compliant broker
LIMA Network Protect
Controlled network availability for emergencies and events: bar service at cell level or per subscriber class while keeping first responders connected.
- Cell-level barring per 3GPP TS 22.011; subscriber control via standardized MAP interfaces
- First-responder prioritization during disaster and overload scenarios
- Tower-change monitoring and multi-CSP Umbrella deployment options
LIMA Location Services
Target location for authorized agencies — on demand or at scheduled intervals, warrant-gated wherever lawful-intercept rules apply and fully audit-logged.
- On-demand and scheduled tracking of authorized targets
- Vendor-independent, across MNO and MVNO networks
- Built on the LIMA Management System, inheriting its regulatory-grade security and audit controls
- Pairs with ATLAS for field-validated coverage and court-defensible location evidence
LIMA Maintenance & Permit Management
Change management for cell-site work: permits, safety interlocks, and third-party-contractor controls on tower maintenance.
- One workflow from permit request to on-site sign-off
- Automated cell-site shutdowns with full audit trails; field-engineer safety interlocks
- Security controls for third-party contractors
Standards coverage
Compliance work lives and dies by the specs. LIMA implements the interception, retention, and availability standards by number — and Group 2000 is a full and active member of the ETSI Technical Committee for Lawful Interception (TC-LI).
| Domain | Standards implemented |
|---|---|
| Intercept handover | ETSI TS 102 232 · ETSI ES 201 671 · 3GPP TS 33.108 · ATIS/J-STD-025-B (CALEA) · ATIS T1.678 (VoIP) · PacketCable CBIS |
| Warrant administration | ETSI TS 103 120 |
| Retained data & disclosure | ETSI TS 102 657 |
| Network availability | 3GPP TS 22.011 (access control & cell barring) |
Turnkey delivery, not a shipped box
Every LIMA engagement is delivered as a project: site survey and solution matrix, architecture, country-specific configuration, installation, testing, training, and project management — then ongoing operation through our two-tier support model with a business-hours Service Desk and after-hours duty engineer.
