This operation is particularly important if the Billing system is used for s of Telecom Operator. X- includes IPTV, VoIP, Internet and Mobile Telephony. Something what is particularly important is to choose the right IT Service Management standard or process from this standard that is needed to implement this system. Most widely used standard in the telecommunications industry is etom standard and implementation of this system falls under the strategy and under the Resource Development & Management Process. This document describes the development of the Billing system for the of Telecom Operator by using principles of the Resource Development & Management Process. The conclusion of the paper should show how successful is the proposed model of Billing system after its implementation in a Telecom Operator in Bosnia and Herzegovina. Key-Words: - etom, Resource Development & Management, IPTV, VoIP, VOD, Internet, Information system, Billing system. 1 Introduction Enhanced Telecom Operations Map (etom) is the most popular standard for IT Service Management in the telecommunications industry [1], [2]. The process that is responsible for creating IT systems or services is called the Resource Development & Management proces [2], [3]. This process is responsible for the design and implementation of information system, Billing system and SAP system of Telecom Operator. The process gives instructions to teams and explains steps how to implement each of these systems that are essential for the normal operation of the Telecom Operator. X- of Telecom Operator includes in one package a combination of these services: IPTV, VoIP, Internet and Mobile Telephony [3]. Formed Billing system should regularly collect information about users of s from the information system and information about consumption for each user from: IPTV, VoIP, Internet or Mobile Telephony platform (Figure 1) [6]. Telecom Operator, which development of Billing system is shown in this document, has a total of 4 packets of : Phone (it includes IPTV and VoIP), Net (it includes IPTV and Internet), Full (it includes IPTV, VoIP and Internet) and Premi (it includes IPTV, VoIP, Internet and Mobile Telephony) [5]. Services with additional charge include: VoIP traffic, Mobile Telephony traffic, Video On Demand (VOD), the using of additional TV ( package), the using of additional TV ( package), the using of an option of 's, Message Waiting Indicator (MWI) option and the option of restriction of VoIP number in the phone book [5]. Figure 1 describes all components of Billing system. ISBN:

2 Figure 1. Components of Billing system The second chapter of the paper describes the development of the Billing system which is connected to the data that the system receives from the information system. The third chapter describes the development of part of system which defines price categories of x-play packages, additional IPTV and VoIP services, VOD packages, VoIP traffic and the traffic of Mobile Telephony. The fourth chapter describes the development of a part of system that collects data about consumption of users from elements for IPTV, VoIP and Mobile Telephony. The fifth chapter describes the formation of the final table for Phone, Net, Full and Premi package without the included value of added tax and with the included value of added tax. Results of testing of the proposed model of the Billing system are attached in the conclusion of the work, after its release into production in a Telecom Operator in Bosnia and Herzegovina. Previous research that the authors have worked in this is based to the improvement of the existing model of etom standard by comparison to ITIL V3 standard. The name of the article that the authors have written is: Improvement of etom standard from the ITIL V3 standard, and it is now in proceedings for the Journal of Global Information Management [9]. 2 Implementation of the Billing system for data from the information system Tables I, II, III and IV show new tables in the formed database of Billing system that this system should get from the central information system of Telecom Operator [4]. Each table should include users from all 4 packages of the [6], [7]. TABLE I. TABLE PHONEUSER1 The name of the The meaning of the identification The some USERSURNAME The surname of user USERPHONE The VoIP number of user if the user has s if the user has a if the user has a package of additional TV MWI if the user has an additional option of Message Waiting Indicator in his VoIP telephone PHONEBOOKPE The name of the if the user uses the option of the restriction of his VoIP number in the Phone Book TABLE II.

TABLE PREMIUSER1 The name of the The meaning of the identification some The USERSURNAME The surname of user USERPHONE The VoIP number of user MWI PHONEBOOKPE if the user has s if the user has a if the user has a package of additional TV if the user has an additional option of Message Waiting Indicator in his VoIP telephone if the user uses the option of the restriction of his VoIP number in the Phone Book 3 Implementation of price cathegories for x-play packages The next important step in the implementation of the Billing system is to define categories of the basic, additional services, Video On Demand service, VoIP Telephony and Mobile Telephony [8]. Table V describes prices of the basic packages for the, table VI describes prices of additional IPTV services, table VII describes prices of the Video On Demand service, table VIII describes prices of calls from one VoIP to the another VoIP or to Fixed Telephony, table IX describes prices of calls from VoIP to the of Mobile Telephony, table X describes prices of calls from the of Mobile Telephony to the VoIP or to the of the Fixed Telephony and table XI describes prices of calls from the of Mobile Telephony to the of Mobile Telephony too [6], [8]. In this prices are included prices of SMS and MMS messages. TABLE V.

THE PRICE OF CALLING FROM MOB NETWORK TO THE MOB NETWORK MOB calling MOB The same operator Price 11 The state operator 2 Price 22 The state operator 3 Price 33 4 Implementation of the Billing system for data from elements Billing system has to collect data from elements for IPTV, VoIP and Mobile Telephony and it has to contain the data about consumption from Video On Demand service, VoIP service and Mobile Telephony service [8]. All data are stored in the tables below and they are collected through the records that are coming directly from the central server of one service. These records fill below tables every 1 hour. Records from elements are formed by internal scripts on the servers of these servers that are implemented to run every 1 hour. At the entrance to the Billing system there is a script that checks the validity of data and in a case of irregular data returns data to the elements. Data from the element for the Internet does not come because they all have fixed values. Table XII describes data s that are coming from elements and which are connected to VOD service which has an additional payment, table XIII describes data s which are coming from the server of VoIP service and table XIV describes data s which are coming from the server of Mobile Telephony [6]. TABLE XII. TABLE VOD The name of the The meaning of the identification number of the user who has some x- ID_VOD_CONTENT identification number of video content VOD_CONTENTS_NAME The name of video content CONSUMPTION_START video content is bought VOD_CONTENTS_PACKA identification GE_UID number of video content category on which is based VOD_CONTENTS_PACKA GE_NAME the charging of video content The name of video content category on which is based the charging of video content TABLE XIII. TABLE VOIP The name of the The meaning of the identification number of the user who has some x- USERPHONE User s VoIP number The telephone RECEIVEDPHONE number of user who has received a call CONSUMPTION_START call is started CONSUMPTION_END call is finished The time duration CONSUMPTION_DURATI of the telephone ON call TABLE XIV. TABELA MOB The name of the The meaning of the identification number of the user who has some USERMOBILEPHONE User s MOB number The telephone RECEIVEDPHONE number of user who has received a call CONSUMPTION_START call is started CONSUMPTION_END call is finished The time duration of CONSUMPTION_DURATI the telephone call ON 5 Establishment of final consumption for packages of When the Billing system collects data from the tables described in chapter I and chapter III, and according to the defined price described in chapter II, then it can make a final sum of consumption for one calendar month [6], [7]. Tables XV, XVI, XVII and XVIII make a monthly sum of consumption by individual users for each package of. Table XIX keeps a consumption of a VOD service for each user as an additional service for IPTV, table XX keeps a consumption of each user for VoIP telephony and table XXI keeps a consumption of each user for Mobile telephony. Table XXII describes a total value of consumer s price without a value of added tax, and table XXIII describes a total ISBN:

5 value of consumer s price with a value of added tax and values in this table represent bills that each user has to pay. TABLE XV.

TABLE USER1 The total value of consumer s price BILLING without a value of added tax TABLE XXIII. TABLE USER The total value of consumer s price with a BILLING value of added tax 6 Conclusion The process of testing performances of implemented Billing system is done 6 months after its release into production. Then the number of users of was The number of users of Phone package was 7.000, the number of users of Net package was 800, the number of users of Full package was and the number of users of Premi package was 300 [5]. Table XXIV shows the number of users who has complained to the bill at the end of sixth month and the number of eligible claims after an internal review for all users. TABLE XXIV. THE NUMBER OF COMPLAINTS BY USERS THROUGH PACKAGES OF X-PLAY SERVICE AND THE NUMBER OF JUSTIFIED COMPLAINTS The name of package The number of complai nts Phone 14 0 Net 2 0 Full 5 0 Premi 1 0 The number of justified complaints The total number of complaints was 22. Internal review for each user has shown that all complaints are not justified. All delivered accounts are entirely correct according to applicable tariffs for IPTV [5], VoIP, Internet service and Mobile Telephony [8]. ISBN:

6 Testing of 22 users has shown that the implemented Billing system by the model described in this document is entirely correct and it can be used for further expansion of new x-play packages of Telecom Operator. Future research in this will be based on the description of the development of specific services of Telecom Operator by the principles of etom processes. 8212; Exploits and Security Analysis, 3 rd International Conference on Information Technology: New Generations, ITNG 2006, pp , April [9] A.
