Solution Strategy & Implementation

Nationwide Deployment

PertSol deployed 26 iNterceptor systems across the operator's pan-India network, supporting 2G, 3G, 4G, NGN, and IMS environments. Deployment, validation, and commissioning were completed within an accelerated six-month timeline.

Seamless Migration

All active interception targets and operational data were migrated from the incumbent platform without downtime. The transition ensured uninterrupted interception operations while maintaining compliance and service continuity.

Unified LI Platform

A centralized lawful interception platform was implemented to streamline target provisioning, warrant management, monitoring, and reporting. The solution established a consistent operational framework across all deployment locations.

Multi-Vendor Interoperability

The platform integrated seamlessly with network elements from Nokia, Ericsson, Huawei, ZTE, UTStarcom, and Alcatel. This enabled interoperability across the operator's diverse telecom infrastructure without requiring network modifications.

Future-Ready Architecture

Built on a modular and scalable architecture, iNterceptor supports existing and emerging telecom technologies. The platform enables simplified upgrades, long-term scalability, and continued compliance with evolving regulatory requirements.
