Evolution of the Telecommunications BSS (Business Support Systems) in Preparation for the Opening of the Telecommunications Market in Costa Rica

SOIN and Oracle worked together on the design and implementation of a convergent billing solution (Oracle Billing and Revenue Management Suite and Oracle AIA/PIPS), as well as CRM (Oracle SIEBEL). This also included the integration of the convergent mediation system from Digital Route (MediationZone) and reconciliation systems from Subex (ROCPS: Concilia and Optima). The comprehensive solution implemented by SOIN, Oracle, Digital Route, Subex, CMA, and Deloitte included: • Infrastructure: Hardware, Operating Systems, Databases, and services for implementation, support, and infrastructure maintenance. • Change Management and Processes: Redesign of business processes and organizational structures, planning and execution of the change management plan, project communication, and training. • Solution Implementation and Accompaniment Services: Analysis, Design, Configuration/Development, End-to-End Testing, User Acceptance Testing, Data Migration, Go-Live Planning, Production Go-Live, Post-Implementation Stabilization, and ongoing support for all Mediation, Rating, Billing, Collections, Dunning, Accounting, International Interconnection Reconciliation, International Call Routing Optimization, National Interconnection Reconciliation, Third-Party Service Management processes, as well as all integration processes with the Client’s legacy and external systems. • Infrastructure and License Support Services: Preventive and corrective maintenance services, infrastructure incident management, and support for licensed application software products (Oracle, Digital Route, Subex), including patch installation.

• Market Share: The Client has remained the market leader for 14 years following the start of competitive operations across all key indicators and continues to maintain a significant market share, positioning itself as the market leader (latest data from SUTEL: positioning of Kölbi, Liberty, Claro, and Telecable – aDiarioCR.com – Costa Rica, https://www.grupoice.com/wps/portal/ICE/quienessomos/comunicacion/sala-de-prensa/noticiasanteriores/kolbi+es+lider+en+mercado+de+telefonia+movil+costarricense). • Brand Strengthening and Competitive Advantage: The potential of the Oracle BRM platform, and its use by other operators in highly competitive markets, prompted the Client to evolve its products and services with a customer-centric focus. Recognizing that its legacy offerings would not be competitive, the Client redesigned its commercial offering using the models natively supported by Oracle BRM. Postpaid mobile plans tailored to Costa Rican consumption profiles exceeded market expectations and surprised new competitors, who had anticipated limited innovation from a state-owned incumbent. • Proactive Technology Updates and Investment Protection, and Evolution 2G → 3G → 4G → 5G: The implemented solution has been continuously upgraded to the latest supported versions of licensed application software throughout 14 years of operation, preserving the Client’s initial investment. Oracle’s industry leadership and the continuous introduction of new functionalities by the vendors (Oracle, Digital Route, Subex) enabled the Client to evolve naturally and progressively across mobile technologies, from 2G to 3G, 4G, 4.5G, and 5G. • The project was implemented over a two-year period, including the migration of both postpaid and prepaid customers. • Billing cycle reduced from months to three days. • Sales cycle time reduced by 99%. • Mobile line activation time reduced by 95%. • Time-to-market reduced by 60%.
