Introduction

The InvoiceControl™ is a tool for reconciliation of all services invoiced to post-paid customers. It compares the customer’s invoiced revenue to the revenue billed and revenue captured at various network checkpoints.

InvoiceControl™ runs either in a batch mode which allows automatic reconciliation of a huge amount of subscribers or on-demand in order to verify a particular charging scenario.

InvoiceControl™ is a scalable solution, which is capable to handle an unlimited amount of customers for a short time period.

Introduction

InvoiceControl™ manages customer hierarchies, tariffs, rates and discounts. It allows import, selection and synchronization of the customer and usage data in order to perform the rating, billing and discounting functionality.

InvoiceControl™ has a built-in rating and billing agent with flexible configuration possibilities which suits almost all requirements.

The discounting module of InvoiceControl™ allows the calculation of volume discounts based on the used service or group of services, combination of origin/destination zones. It allows definition of one or more discounts with pre-defined calculation priorities.

Functionality

InvoiceControl™ imports the customer data, tariff and product information from the invoice print file produced by the in-house billing system

Price and product definitions can be specified by

using the build-in InvoiceControl™ user interface or imported from the in-house billing system.

InvoiceControl™ provides charging sources synchronisation interfaces which avoids missing or duplicates of records during the reconciliation procedure.

After rating, billing and discounting stages InvoiceControl™ compares the results with the invoices produced by the billing system and creates detail reports for the differences.

Supported charging scenarios

The rating agent delivered with the InvoiceControl™ is capable to calculate charges from EDR (Event Data Record), coming from different kind of network elements – mobile and land-line switches, TAP, SMS/MMS centres, WAP gateways, GPRS/UMTS nodes, IN platforms etc.

InvoiceControl™ supports almost any known charging scenarios like MOC/MTC/CF charging, Friends & Family, VPN groups, VAS (Value Added Services), wholesale and retails revenue sharing models etc.

The price calculation is based on the following groups of parameters: • Geographical – network, distance, origin/destination, routing

• Service related – service id, kind of service, direction

• Volume related – duration, volume, number of events, pre-priced

• Time dependency – daily time block (peak/off-peak), weak day, holiday

• Customer related – tariff indicator in the customer tree, VPN (F&F)

dependency, relation to assigned products and bundles.

Tariffs, Products and discounts setup

InvoiceControl™ has an internal data representation of the tariffs, products and discounts definitions used in the in-house billing system.

InvoiceControl™ is capable to import prices, tariffs and products from the external system or to use API (Application Programming Interfaces) to access this directly.

Optionally InvoiceControl™ can be delivered with a WEB based GUI (Graphical User Interface) for maintaining all related data.
