Helping a global telecom leader architect a distributed multi-database Oracle BRM rating engine for multi-million SIM IoT deployments
Client operates a global-scale B2B billing engine built on Oracle Billing and Revenue Management (BRM). The platform powers diverse enterprise Internet-of-Things deployments spanning connected vehicle fleets, industrial telemetry, smart utility metering, and global asset tracking infrastructure.
Unlike consumer cellular operations, the client operates in a complex multi-tiered enterprise environment where global corporate customers own hundreds of child accounts managing millions of active connected endpoints, with billing rollups and volume discounts aggregating at the parent account level. Intellious embedded billing specialists within the Architecture and Scalability Review Team to re-engineer core rating paths, customize pipeline memory caching, and deploy an active-active multi-database foundation — eliminating database deadlocks, resolving multi-IMSI roaming across borders, and enabling real-time visibility for enterprise customers.
Standard out-of-the-box Oracle BRM is architected around centralized databases and single-SIM retail relationships, and the client's scale broke those assumptions on several fronts. Its account hierarchies couldn't handle deep parent-child relationships with millions of SIMs rating dynamically at the parent level, while a sharded multi-database topology caused cross-database rating deadlocks. Multi-IMSI devices roaming across borders triggered pipeline failures, and CDR surges created I/O bottlenecks that threatened 24/7 availability and slowed client-facing dashboards.
Intellious embedded billing specialists to re-architect the rating engine for cross-database, multi-tier account hierarchies, resolve multi-IMSI routing across international networks, and build a resilient high-availability foundation with real-time visibility for enterprise customers.
The engagement transformed a strained rating architecture into an industrial-grade billing foundation built for global enterprise IoT expansion — enabling horizontal multi-database scaling, seamless multi-IMSI resolution with zero revenue leakage, and 99.99% rating availability with sub-second dashboard performance for corporate clients.
