Core Billing and Rating Modernization: BRM/ECE Upgrade to BRM 12/15 – Cloud-Native BRM ECE

Involved Institutions: Costa Rican Electricity Institute (ICE)

Provider: SOIN Soluciones Integrales S.A.

Project Year: 2023 and 2025

The Challenge:

The client, a leading telecommunications and energy institution in Costa Rica, had been operating its Billing and Revenue Management platform on Oracle BRM version 7.5 for more than five years. This version exhibited technological obsolescence, scalability limitations, constraints on integration with modern (cloud-native) architectures, and a sustained increase in operational and security risks. The challenge extended beyond the critical upgrade of the core billing system to Oracle BRM version 12—which represented a five-version leap—to the comprehensive modernization of the rating and billing ecosystem. The objective was to prepare the platform for the demands of network evolution toward 5G, where the system is responsible for real-time rating and billing of millions of daily transactions associated with highly complex products and services, while preserving the integrity of millions of historical records, maintaining interoperability with satellite systems, and complying with the demanding operational windows of a mission-critical telecom environment. The goal was to strengthen operational resilience, improve high availability, enable maintenance activities with no service impact, and empower the business to respond more agilely to market dynamics.

Our solution:

SOIN, as Oracle’s strategic partner, designed and executed a comprehensive modernization plan that included: • Core and ecosystem evolution: modernization of the billing and charging core and ecosystem (BRM, ECE, PDC, OCOMC, OC3C). • Detailed analysis and planning of the BRM ecosystem, customizations, business flows, and integrations, defined from the outset with a cloud-native approach. • Design of a logical and technical architecture prepared for containerization, horizontal scalability, and future cloud migration. • Phased migration with controlled development and quality environments. • Modernization of customizations and extensions, ensuring compatibility, standardization, and optimization on BRM 12. • Execution of functional, performance, and load testing focused on critical billing processes. • Training and knowledge transfer to ICE technical and operational teams, incorporating concepts, tools, and practices aligned with modern architectures. • Adaptation and validation of interfaces with satellite systems. • Extensive volume and performance testing under complex commercial scenarios. • Planned and successful production go-live executed with no business impact. • Implementation of a rating infrastructure in an active-active configuration across geographically separated production nodes.

Results:

• Fully modernized billing and charging ecosystem implemented on Oracle BRM 12 and 15. • Guaranteed operational continuity, with no impact on customer services. • Technology foundation prepared for cloud-native architectures, while still operating on-premises. • By addressing structural, functional, and logical architecture changes as part of the BRM 12 and 15 project, the future evolution from on-premises to cloud is now projected as a predominantly infrastructure-driven initiative, significantly reducing risk, timelines, and complexity. • The BRM 12 project established the architectural, technical, and knowledge foundations under a cloud-native approach, while the evolution to BRM 15 consolidated a modern, resilient, active-active platform, ready for 5G and with substantial improvements in time-to-market. • Initiation and enablement of a continuous upgrade process for the billing and rating platform (BRM/ECE/PDC/OCOMC/WSM), significantly reducing upgrade risk. This process remains active today; as of 2025, BRM/ECE version 15 is in production, enabling annual upgrades with no operational or functional business impact. • First worldwide operation of BRM v15 in a fully convergent prepaid and postpaid active-active configuration. • Platform fully prepared for evolution toward 5G services. • High availability, operational resilience, and maintenance activities with no service impact.
