Pegasus Billing Systems

BIS 3 {Billing and Information System 3} is a highly customizable integrated billing and customer care solution for mobile radio network operators used to bill:-


Trunking  (MPT1327/TETRA)

Fixed Network (PSTN), Cellular or GSM.

Wireless providing voice and/or data services for commercial, private or public safety usage.

The BIS 3 billing system has initially been developed for and delivered to public trunking operators throughout the world, including Europe, South East Asia and Africa.

It has been customized to be compatible with numerous trunking systems. Due to its modular nature and open APIs, it can be adapted to virtually any mobile radio network system.

BIS 3 was conceived from its inception to satisfy some very specific requirements, in particular:

a. to actually print out invoices according to the customers' needs as quickly as possible

b. to have an extremely flexible ta-riffing price model list configuration

c. to provide an easy to use customer care system with customer, account, contract, subscriber relationships definitions

d. to be able to re-bill easily

e. to be able to access, maintain and view the raw call data (CDR) easily.

Customer References

BIS 3 has been installed by some of the leading trunking operators in Germany, including:

 Quckfunk (Mannesmann/Motorola)/Vodaphone GmbH, Frankfurt am Main

 DBF Bündelfunk (Quandt) GmbH, Wuppertal

 Mobilkom GmbH, Lake Constance

In South East Asia BIS 2 has been deployed by operators such as:

 Mobilkom in Manila/Cebu Philippines

 PT Mobilkom in Jakarta, Indonesia

 STCC in Bangkok, Thailand

 Singapore Telecom, Singapore

In Africa, Starlight, has deployed BIS 2 in Kampala, Uganda.

Target Customers

BIS 3 is ideally suited for network operators who provide mobile radio services for public usage, and who need to produce invoices for their customers. Besides, it can be used for private mobile operators who need to invoice network usage to specific departments, or simply as a tool to divide network usage into different cost centers for accounting purposes.

The software can be adapted to the needs of the individual network operator as it is configurable based upon a number of building blocks that can be individually adapted by the administrator. For example, the administrator can define price lists to be used based upon either static or dynamic parameters.

Features and Benefits

BIS 3 provides a lot more than just an invoicing and customer care module. Following are some of its very useful features.

Financial Bookkeeping Interface


The billing system can provide different Financial Bookkeeping interfaces like SAP, SCALA, DATEV, KHK or new interfaces can be easily added.

Banking Interface


Banking interfaces like DTA (an automatic bank account debiting/crediting interface in use in Germany) can be supplied.

Flexible licensing structure

BIS 3 can be used to invoice in start-up situations, however it's structure and underlying Oracle database allows it to be extended to handle mature invoicing situations where millions of customers are being billed.


Network Operators need only buy a license that is adequate for their immediate and short term needs.


Additional customer processing licenses can be added remotely by email license at any time.


Example: A start-up system can be licensed to handle up to 1000 customers. After growth has occurred, this license can be extended up to 1,000,000 customers.

Roaming, Inter Carrier Operator Billing, ISP Billing and Remote call-data collection are optional modules that enhance the basic feature set of BIS 3. Contact us for further information.

Standards-based solution


The billing software runs on Microsoft Windows XP and uses an Oracle (Versions 7.3, 9i, 10g) database on the back-end.

Price Lists and Banking data

This feature allows network operators to define unlimited different price lists and details about the network operators own bank accounts where money will be collected to or paid in.

Call detail record data import:

This facility provides the ability to import all of the customers call data into the Oracle database for use by BIS3 

PCIH: The call data can be collected directly from the switch (Nokia, Ericsson, Nortel, Rohill, Rohde&Schwarz Bick, etc.) using the Ipsys PCIH mediation solution which is directly connected to the switch.


PCIH: (Pegasus Call Information Handler) has several interface options (LAN, serial, etc.) through which the communication with the switch is established and call detail record data is continuously collected.


PCLF (Pegasus Call Logging Facility) is then used to automatically collect and aggregate call detail records from one or more remote PCIHs installations.

Customer Care


Network Operators can save all of the necessary information about each customer using the customer care facility. This information includes details such as names, addresses, phone numbers, bank names, accounts, mobile numbers, security numbers, etc.

Billing Cycle


After details about each customer, customer account, customer contract, customer unit, (up to 4 levels deep) has been added to the system, the call data has been imported and price lists have been defined together with the billing cycle management parameters, the billing run can be set to run periodically.


The billing run creates one converged invoice per customer. A detailed invoice listing all calls made is available if needed, or a summary invoice. A financial accounting interface summary file can be created. Optionally, a banking debit/credit file that can be given to the bank for automatic money collection.
