Design Prototype Billing System for Voice Over Internet Protocol Services Based onSession Initiation Protocol Moch. Zulfikhar Luthfillah 111040134 Advisors : Agus Ganda Permana, Ir. MT. Asep Mulyana, ST. MT.
Background • Experts predicted that almost 75% of telecommunications traffic in the world move towards VoIP in a period of five years. • The growth of Internet Telephony Services Provider (ITSP). • ITSP need reliable Voice over Internet Protocol Billing System.
Objective of Research • Design of prototype of VoIP Billing System in order to Internet Telephony Services Provider in the future. • Implement and analyze rate scheme at TELKOM in VoIP Billing System has been designed by writer. • Known and analyze the time process of Call Detail Record (CDR) in one call in VoIP Billing System Server.
Problem Formulation • How to make VoIP Billing System at Local Area Network, so that later can be implemented in the Internet Telephony Services Provider. • How to implement rate scheme at TELKOM in VoIP Billing System has been designed. • How to analyze the time process of Call Detail Record in one call in VoIP Billing System Server.
Scope • Parameters which analyzed are the rate scheme and the time process of Call Detail Record (CDR). • Record the duration of call, not recording the volume data. • This research using Session Initiation Protocol for relationship between client and server, and using Inter Asterisk Exchange for relationship between one to another server. • Test ing is done on the softswitch network has been built and configure by the author with using two different server. • Not discuss the issue of rate regulation from VoIP billing system.
Basic Theory VoIP Overview
Call Detail Record • A Call Detail Record (CDR) is the computer record produced by a telephone exchange containing details of a call that passed through it. • CDR parameters : • Time of Call • Talk Time • Destination Number • Caller number • Location • Rate
VoIP Billing System • VoIP Billing is a Call Detail record recording system that done by ITSP, whether a call between the same computer and calls to the circuit-switch network such as PSTN.
The Important of VoIP Billing Parameters Recording capacity and the quality of a VoIP billing can be directly influenced by several key factors, namely: • Time process recording • The accuration of billing system • The capacity of billing system
Rate Scheme of Telecommunication • Flat Pricing • Pricing based on call time • Pricing based on the distance • Pricing based on call duration
Scenario 1 (Local Call) Scheme Rate for Local Call
Scenario 2 (Interlocal Call) Scheme Rate Interlocal (Monday to Saturday) Scheme Rate Interlocal (Sunday or Holiday)
Analysis of Implementation Result • Call Setup and Call Teardown Sistem Billing
Scheme Rate Analysis • Scheme Rate for Local Call (00.00-09.00 distance 0-20km) • Scheme Rate for Local Call (09.00-15.00 distance 0-20km)
Scheme Rate Analysis • Scheme Rate for Local Call (15.00-24.00 distance 0-20km) • Scheme Rate for Local Call (00.00-09.00 distance >20km)
Scheme Rate Analysis • Scheme Rate for Local Call (09.00-15.00 distance >20km) • Scheme Rate for Local Call (15.00-24.00 distance >20km)
Scheme Rate for Interlocal Call • Monday to Saturday (00.00-23.00 Zone I)
Scheme Rate for Interlocal Call • Sunday or Holiday (00.00-23.00 Zone I)
Scheme Rate for MultioperatorCall • This Scheme rate, not have standard scheme for the connection to the PSTN Network
Time Process Recording Billing Time Process for server billing System : Tproses = T1 + T2 + T3 description: T1 = t2 – t1 T2 = t4 – t3 T3 = t5 – t6 Call Duration : Tlamabicara = Tbye - Tanswer
Conclusion • Scheme rate at this time which is the standardization of TELKOM scheme can be implemented to VoIP Billing System. • Can be applied billing system for VoIP calls to PSTN Network, but there are no rate regulations that set. • the process of billing a VoIP system can be influence by several factors, among others, computer specifications and trunking system. • The process of Local billing is best, namely 1,29775 seconds and the process of Multioperator billing is worst, namely 1,6333 seconds. • The Process of VoIP billing system by using the background traffic 20Mbps obtained average process time of 1,62045 seconds.
Suggestion • Research are expected next VoIP billing system capable of recording to the volume of data sent. • VoIP Billing System not only integrated with PSTN Network, but can be integrated with GSM/CDMA Network • Government regulations are expected to set the VoIP so that VoIP can be applied globally. • Research on system security VoIP billing system. • Billing system was developed for the video call, Fax, IPTV, etc.
