Key features
Explore the essential functions of our OCS Core.
Each feature is modular, robust, and built for carrier-grade deployments.
Flexible charging modes
One-to-one or chunked units; in-session or end-of-session; configurable precision/rounding; current or past-date corrections.
Accounts, lifecycle & IDs
Prepaid/postpaid cycles, registration/activation, admin blocks, top-up extensions; groups & profiles with primary and alternate identifiers.
Powerful rating engine
Scripted conditions, operations and ordered ratings: pick tariffs by zones, calendars, counters or attributes; execute actions under rules.
Extensible attributes
Custom flags, thresholds and values on accounts, groups or profiles — used in rating rules and exported to CDRs.
Product catalog
Retailers, events, services, offers & groups; tariffs, rating plans and subscriptions — structured for clean monetization.
Services & selection
Event (SMS) and session (voice/data) charging. Interface-aware selection + offer groups; multi-service rating.
Session resilience
Offline settlement for interrupted sessions; resumptions and auto-termination on inactivity via scheduler scans.
Balances & bundles
Monetary wallet + mono/multi-bucket bundles, shareable in hierarchies; thresholds, top-ups, transfers and refunds.
Tariffs & in-session switch
Usage-based, fixed-cost and free tariffs with time versions. Mid-session rate change correctly split across old/new values.
Counters & access rules
Per-account/group/global counters with cycles; black/white lists; zone lists & matrices for origin/destination screening.
Notifications & exposure
Balance & throttling notifications to external systems, REST/HTTP exposure (SMS/voice/data), and structured CDR output for BI/finance.
