Roaming Settlement Layer

Settle roaming in hours.
Not in forty-five days.

Run a private roaming settlement chain where every call detail record is anchored the moment a subscriber roams onto a partner network. The Roaming and Clearing, Escrow and Conditional Settlement, and Trade Finance Documents modules net each operator's balance automatically, with a regulator audit layer watching the same record.

The Foundation

The Execution Mechanics

Replace month-long clearing house reconciliation with a shared, tamper-evident ledger of every roamed session.

01.

CDR Anchoring

Anchor usage at the source. Every call detail record from a roamed voice, data, or SMS session is hashed onto the settlement chain as it is rated, so both the home and visited operator write to one record instead of exchanging TAP files days later.

02.

Automated Net Settlement

Collapse bilateral balances into one figure. The Roaming and Clearing module continuously nets each operator's inbound and outbound charges, producing a single settlement amount per partner rather than a manual month-end reconciliation.

03.

Conditional Escrow

Release funds only on agreement. Escrow and Conditional Settlement holds the net amount and releases it when both operators' anchored totals match, removing the disputes that stall traditional clearing.

04.

Trade Finance Documents

Bind the paperwork to the payment. The Trade Finance Documents module anchors the roaming agreement, tariff schedule, and settlement statement by digest, so the commercial terms and the money move against the same evidence.

05.

Regulator Audit Layer

Give the regulator a live window. A read-only node lets the national authority inspect anchored volumes and settlement statements directly, replacing after-the-fact reporting with a verifiable view.

06.

Dispute-Free Reconciliation

Remove the argument entirely. Because both operators rate against the same anchored CDR set, contested volumes disappear and reconciliation disputes fall to zero.

The Settlement Lifecycle

Follow a single roamed session from the visited network through net settlement and regulator inspection.

Smart Contract Anatomy

Cerulea decomposes roaming settlement into modular contracts that anchor usage, net balances, escrow the payment, and expose the cycle to the regulator, with no clearing house sitting between the operators.

Applicability Across the Spectrum

Anchored inter-operator settlement is a horizontal capability. Here is how different players in the roaming value chain put the shared ledger to work.

Mobile Network Operators

Settle roaming with every partner from one net figure per pair, compressing the cycle from forty-five days to seventy-two hours and removing the reconciliation team's monthly file war.

Network & Execution Architecture

Whether you are bridging a legacy mediation and billing stack or streaming rated CDRs from a modern charging system, Cerulea routes both into one shared settlement record.

Track A: Enterprise Billing Bridging

For carriers on legacy mediation and clearing stacks. Rated CDRs are translated into signed on-chain anchors through the API gateway, and net positions post back to the billing system automatically.

Track B: Real-Time Charging Capture

For operators on modern online charging. Each rated session is signed at the charging node and routed straight to the settlement chain for continuous netting.

Technical Methodology

The legacy timeline reflects inter-carrier settlement integration benchmarks. Wiring each operator's mediation stack, building custom netting and escrow logic, and standing up a regulator audit interface for an average partner network takes a baseline of 9 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your settlement and netting rules into pre-audited WebAssembly binaries and provisions the shared clearing ledger and audit layer instantly.
