Transcript

  • 1. Moch. Zulfikhar Luthfillah 111040134 Design Prototype Billing System for Voice Over Internet Protocol Services Based on Session Initiation Protocol Advisors : Agus Ganda Permana, Ir. MT. Asep Mulyana, ST. MT.
  • 2. 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.
  • 3. 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.
  • 4. 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.
  • 5. 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.
  • 6. Basic Theory VoIP Overview
  • 7. 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
  • 8. 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.
  • 9. 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
  • 10. Rate Scheme of Telecommunication
    • Flat Pricing
    • Pricing based on call time
    • Pricing based on the distance
    • Pricing based on call duration
  • 11. Design and Implementation
  • 12. Scenario 1 (Local Call) Scheme Rate for Local Call Jarak (Km) 00.00-09.00 09.00-15.00 15.00-24.00 Rupiah per Durasi 0 s/d 20 250 / 3 menit 250 / 2 menit 250 / 3 menit > 20 250 / 2 menit 250 / 1,5 menit 250 / 2 menit
  • 13. Scenario 2 (Interlocal Call) Scheme Rate Interlocal (Monday to Saturday) Scheme Rate Interlocal (Sunday or Holiday) Zone Jarak (Km) 06.00-07.00 07.00-20.00 20.00-23.00 23.00-06.00 Rupiah Per Menit I > 30 s/d 200 645 1290 645 325 II >200 s/d 500 915 1815 915 460 III > 500 1135 2270 1135 570 Zone Jarak (Km) 06.00-23.00 23.00-06.00 Rupiah Per Menit I > 30 s/d 200 645 325 II >200 s/d 500 915 460 III > 500 1135 570
  • 14. Scenario 3 (Multioperator Call)
  • 15. The Process of VoIP Billing System
  • 16. Design Interface VoIP Billing System
  • 17. Analysis of Implementation Result
    • Call Setup and Call Teardown Sistem Billing
  • 18. 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)
  • 19. 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)
  • 20. 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)
  • 21. Scheme Rate for Interlocal Call
    • Monday to Saturday (00.00-23.00 Zone I)
  • 22. Scheme Rate for Interlocal Call
    • Sunday or Holiday (00.00-23.00 Zone I)
  • 23. Scheme Rate for MultioperatorCall
    • This Scheme rate, not have standard scheme for the connection to the PSTN Network
  • 24. Time Process Recording Billing Time Process for server billing System : T proses = T 1 + T 2 + T 3 description: T 1 = t 2 – t 1 T 2 = t 4 – t 3 T 3 = t 5 – t 6 Call Duration : T lamabicara = T bye - T answer
  • 25. Time Process of VoIP Billing System
  • 26. The influence of Background Traffic on VoIP Billing System
  • 27. 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.
  • 28. 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.
