YENRA HOTSPOT BILLING RECONCILIATION Guide: https://yenra.com/wireless-internet-bill-consolidation-settlement-service/ Prepared September 12, 2026. Editable operations aid. Protocol background: https://www.rfc-editor.org/rfc/rfc2866.html Actual charges, taxes and settlement follow applicable agreements. INSTRUCTIONS Preserve original events. Build a ledger with stable session references and a documented duplicate rule. Apply the correct tariff version. Hold ambiguous records for an approved exception process. Reconcile retail and wholesale totals separately. Use test identifiers; protect actual customer activity. FICTIONAL EXAMPLE - USD, no taxes, fees or other costs Access server: A; session: S-104; final duration: 1250 seconds. Retail: USD 0.10 per STARTED minute, capped at USD 3.00 per session. Billable minutes = ceil(1250 / 60) = 21. Retail = min(21 * 0.10, 3.00) = USD 2.10. Wholesale: USD 0.06 per STARTED minute, no cap in this example. Wholesale = 21 * 0.06 = USD 1.26. Difference = USD 0.84 before other costs; this is NOT net profit. Retransmitted final record: retain evidence, create NO additional charge. S-105 with missing final duration: hold for documented exception handling.
