BSS
A BSS that earns revenue and proves it isn't leaking. Convergent real-time charging across voice, data, SMS, VAS, and IoT; an integrated fraud detection system that auto-suspends compromised SIMs within a second; and continuous CDR reconciliation between BSS and OCS so revenue assurance stops being a quarterly spreadsheet.
Convergent real-time charging on one rating engine
Voice via Ro/CAMEL, data via Gy SCUR, SMS and MMS via ECUR, VAS and IoT on the same engine. Quota grant, renewal, and Final-Unit-Indication for graceful session termination. Postpaid mediation arrives via Rf. Spending limits coordinate with the PCRF over Sy so a bundle exhausting on a Friday doesn't surprise anyone on Monday.
Fraud detection that earns its own keep
IRSF detection blocks abnormal volumes to International Premium Rate Numbers, with destination prefix lists refreshed via i3forum threat feeds. SIM-box pattern detection flags unnatural A-number distributions and synchronised CDR signatures. Velocity checks catch impossible-travel roaming. SS7/Diameter firewall per GSMA FS.11/FS.19. Compromised SIMs are suspended within one second via Diameter Sy plus MAP DeactivateSS — every action lands in the SIEM with full signalling context.
CDR mediation + continuous revenue assurance
Mediation collects, normalises, and deduplicates xDR records from the PGW (GTP-prime / Ga per TS 32.295), MSC, and SMSC. The Revenue Assurance module continuously reconciles BSS and OCS records, surfacing discrepancies as they emerge rather than at month-end close. SAN-backed archive with a 12-month retention floor.
