About the programme
Course Overview
Every call, session and data record a network generates has to pass through a mediation chain before it ever reaches an invoice, and each hop in that chain, from switch to mediation platform to rating engine to billing system, is a place where usage can be lost, duplicated or misrated. This course teaches billing mediation design alongside the revenue assurance controls that catch the resulting leakage before it erodes margin. Participants trace a call detail record from network element collection through normalisation, correlation and rating, learning where format mismatches, timing gaps and duplicate records typically occur. Sessions cover building reconciliation controls between network usage counters and billed volumes, detecting systematic under-billing or zero-rated leakage, and auditing interconnect and roaming settlement statements against actual traffic. The course also addresses revenue assurance governance: prioritising controls by financial exposure, building a leakage register, and reporting recovered revenue to finance and executive stakeholders in terms they can act on.

Audit interconnect and roaming settlement statements against actual network traffic records.
Prioritise revenue assurance controls using a financial exposure and likelihood scoring model.
Build a leakage register that tracks root cause, recovered revenue and control ownership.
Report revenue assurance findings and recovered value to finance and executive stakeholders.

01The Billing Mediation Chain
2 sessions · 8 points
Session 1Call Detail Record Collection and Normalisation
- Map how call detail records are generated at switches, gateways and packet cores before collection.
- Normalise record formats across vendor equipment so downstream rating logic applies consistently.
- Identify timing and time-zone mismatches that cause records to be dropped or duplicated during correlation.
- Set up completeness checks that confirm every network element's expected record volume actually arrives.
Session 2Correlation, Rating and Duplicate Detection
- Correlate related records, such as call legs or session start and stop events, into a single billable event.
- Configure rating engine logic for usage-based, flat-rate and bundled tariff structures without double charging.
- Detect duplicate records introduced by mediation platform retries or network element resets.
- Test rating changes in a staging environment before they affect live customer bills.
02Revenue Leakage Detection
2 sessions · 8 points
Session 1Reconciling Network Usage Against Billed Volumes
- Compare network element usage counters against mediated and billed volumes at each pipeline stage.
- Build automated variance reports that flag discrepancies above a defined materiality threshold.
- Investigate systematic under-billing caused by misconfigured zero-rating or promotional rules.
- Trace intermittent leakage to specific network elements, mediation nodes or rating rule changes.
Session 2Interconnect and Roaming Settlement Assurance
- Audit interconnect settlement statements against actual inbound and outbound traffic records.
- Reconcile roaming usage data records against partner operator settlement files under industry exchange formats.
- Identify disputed traffic and manage the evidence pack required for settlement negotiation.
- Monitor high-risk interconnect routes for traffic pumping or bypass fraud patterns.
03Control Design and Prioritisation
2 sessions · 8 points
Session 1Building a Revenue Assurance Control Framework
- Score revenue assurance risks by financial exposure, likelihood and existing control coverage.
- Design preventive controls at product launch to stop leakage before a service goes live.
- Set detective controls with defined thresholds, owners and escalation timelines for exceptions.
- Maintain a control catalogue that maps each control to the process and system it protects.
Session 2Leakage Register and Recovery Tracking
- Maintain a leakage register recording root cause, financial impact and remediation status for each finding.
- Estimate recoverable versus unrecoverable revenue for historical leakage incidents.
- Track remediation actions through to system fixes and confirm leakage has actually stopped.
- Distinguish revenue assurance leakage cases from suspected fraud requiring a separate investigation.
04Governance and Stakeholder Reporting
2 sessions · 8 points
Session 1Revenue Assurance Governance and Team Structure
- Position the revenue assurance function relative to finance, fraud and IT within the operating model.
- Define escalation paths for findings that require product, billing or network configuration changes.
- Set service level expectations for investigating and closing high-priority leakage cases.
- Coordinate with internal audit on control testing and evidence retention requirements.
Session 2Reporting Recovered Value to Finance and Executives
- Translate technical leakage findings into revenue impact figures that finance teams can validate.
- Present a quarterly revenue assurance report showing recovered value against target.
- Build a business case for mediation platform or control investment based on demonstrated leakage.
- Communicate residual risk and unresolved exposure clearly to executive stakeholders.
