Program for tariffication of calls in telephony services

The market of the IP-telephony and, all the more, traditional telephony has reached the top of its development. Ensuring of growth in such a market depends not so much on attraction of new subscribers, as on getting maximum profitability from the existing subscribers base.

The billing solution (program for tariffication of calls) based on B&CC Billmaster allows to retain subscribers and ensure long-term business growth due to high performance, scalability and flexibility. This solution makes it possible to combine different telephony services, which are provided through the use of different technologies, and different accounting schemes.

Tariffication of calls: realization of the solutio

The solution, which was developed by Inline Telecom Solutions, is designed for operators of local, city, trunk and long distance telephone communication, as well as of VoIP telephony. This program allows to organize accounting and tariffication of calls, with the help of the RADIUS protocol at access gates, as well as by way of records, which contain information about calls made (СDR, UDR, etc.), loaded from the automatic telephone system.

Основные компоненты этого решения:

Voice over IP module is used for provision of VoIP-services and allows to service regular subscribers, as well as those, who register with payment cards. The module includes the voice menu system, which organizes interaction of subscribers with the access server by way of DTMF signals.

On connection of subscribers the access server starts the script in the interpreted language TCL, which is meant for organization of voice menu. The voice menu allows subscribers to interactively manage VoIP-services: dial phone numbers, replenish personal accounts, receive information. Subscribers select menu items, and the script interacts with Billmaster over the RADIUS protocol, for example, sends authorization requests.

The module allows to carry out authorization in the following ways: by PIN-codes, by ANI, limitation of authorization by ANI, by ANI in case of PBX use, limitation of authorization by DNIS.

The information about duration of calls comes over the RADIUS protocol. When calls are completed there is performed final calculation of cost and charging of money from personal accounts. The Voice over IP module allows to create a random number of tariff plans. Main possibilities of tariffication:

calculation of call cost, which depends on directions (telephone zones) and time, when calls were made;
rounding of call duration;
charging of subscription fee;
one-time charges;
volume price coefficients;
multi-login management;
partner fees;
calculation of Call-center service costs.

The module of transit IP-telephony is used for accounting of voice traffic and financial liabilities, which arise on its transfer. Transit voice traffic comes from certain VoIP-operators and is transferred to other ones. The data about transit voice traffic come over the RADIUS protocol and characterize duration of calls.

The module allows to accumulate statistics about quality of calls: percentage ratio of successful and unsuccessful calls (Average Success Rate, ASR), average duration of one call (Average Call Duration, ACD).

The module of transit IP-telephony supports the following tariffication possibilities:

calculation of voice traffic cost, taking into account telephone zones and schedules;
rounding of call duration;
periodic charges;
one-time charges;
volume price coefficients.

The module of fixed telephony is intended for tariffication of calls in public switched telephone networks (PSTN). The information about duration and direction of calls is generated by the equipment exchanges and passed to Billmaster as CDR-packages.

The module supports the following tariffication possibilities:

calculation of call cost taking into account telephone zones and tariffication schedules;
charging of subscription fee;
one-time charges;
rounding of call duration;
volume price coefficients;
partner fees.

Advantages of the solution

The solution of the company Inline Telecom Solutions for telecoms operators, that provide telephony services, allows to realized advance and credit payment schemes (prepaid and post-paid) for services of traditional and IP-telephony, including the possibility of accounting and tariffication of additional services and usage of the voice menu (IVR), which can be provided to IP-telephony subscribers.

This solution can be well integrated with different network equipment and third-party software, and it grants to subscribers the possibility to get information about used services, payments and tariffs through the Web-interface ("Personal profile").

Advantages of this solution include the following:

flexibility of service provision, which allows to organize tariffication of calls according to very different scenarios, including consideration of time of the day, day of the week, quantity of used services, etc;
availability of voice menu (IVR), which allows subscribers to interactively manage access to their services;
high-performance tariffication of calls and provided services;
support of agent schemes of connection to long-distance communication operators;
wide possibilities for bills drawing, capability of independent "building" of required reports;
short term implementation of this solution – it can be launched within two months;
optimum cost of solution, as it is possible to use only those functional possibilities, which are required;
optimum cost of solution, as it is possible to use only those functional possibilities, which are required.
