  1. ITU-APT FDN of India Relevance of Interconnect in NGN Environment H C Soni VP ITU-APT Foundation of India hcsoni@gmail.com

  2. India: Present status as on 31st Jan 09 ITU-APT FDN of India

  3. How to balance reducing ARPU and manage growth: Use USO: for Tower, power, W/L and OFC penetration Bring in Virtual operator concept Share Infrastructure Operators wants to penetrate into rural areas But People have less paying capacity (US$ 1-2 pm) Thus Tariff is reducing ARPU reducing ITU-APT FDN of India What is happening

  4. ITU-APT FDN of India What is infrastructure • Passive: Tower, Power, Land and Building etc. • Active • Switches: TDM and IP based • Transport network • OFC • Wireless: M/W, Satellite • Access network • Copper: Local loop • Fiber: L/D, Back Haul and FTTX • Wireless: BTS • Applications • Billing Systems

  5. Example of tourism Industry Bulk Ticketing, Pooled Pick-up drop, Bulk hotel booking, Group Sight seeing, Bulk lunch/Dinner Thus to get maximum benefit: Why not Share/Pool Access Network Carrier/Transport network Billing System Applications Infrastructure passive and active Common interconnect ITU-APT FDN of India What to share?

  6. ITU-APT FDN of India Interconnect Issues • Separate Network for Basic/Mobile (Voice) and for Data • Huge growth- Of the order of 15 Million mobile connections in a month in India • Increasing numbers of Application developers, no. of Oprs and their Traffic • Every Basic/Mobile operator have to have interconnection (or transit through) with each other and with many NLD and ILD oprs

  7. ITU-APT FDN of India Present Interconnection BS1 BS2 BS3 ILDO1 NLDO1 ILDO2 NLDO2 MO1 MO2 MO3

  8. ITU-APT FDN of India Results • Sub-optimal utilization of resources • Inefficient handling of calls • High operational cost for managing inter operator connections • Inter opr/carrier billing problems • Complexity in settlement in Interconnect usage charges • Increase in CAPEX and OPEX

  9. ITU-APT FDN of India Challenges • Reduce High interconnection cost • Reduce Connection at different levels and at many places and Complex routing at every point • Reduce Huge requirement of ports and their cost • Physical provisions at different places causes delay and need more capacity • Resolution of billing disputes/court cases

  10. ITU-APT FDN of India What is the Solution: NGN:ICE • Open and Fragmented Architecture • Best breed of products • Much Better Performance • Desired Quality of Service • Efficient inter working ‘And what not’ Thus NGN interconnect Exchanges can be best solution for inter connecting

  11. ITU-APT FDN of India NGN/IP based Interconnect Exchange BS1 BS2 BS3 ILDO1 NLDO1 INTERCONNECT EXCHANGE ILDO2 NLDO2 MO1 MO2 MO3

  12. ITU-APT FDN of India Domestic International NGN switch LIS LIS NGN Net SBC SBC I E IN MG MG TDM switch TDM Net Billing/CS ASP

  13. ITU-APT FDN of India Advantages • Network planning fast and simple leads to reduction in cost and port charges • Simple network interconnection using Electrical/Optical, GE/STM interfaces • Reduction in number of links • Simplifies digit analysis for all inter operator and long distance calls from the switches connected to it

  14. ITU-APT FDN of India Advantagescontd. • Fast provision/augmentation of PoIs as everybody knows physical location of IC • Integration of different service providers at one point • Help in quadruple (Voice, Video, Mobile TV and data) play in inter opr environment • Help in convergence of services, application and provisioning • Simplification in carrier selection function

  15. ITU-APT FDN of India Advantagescontd. • Integrated inter carrier billing/Clearing house • Less connection: less disputes: less court cases • Inter operator charging, based on GoS, Content and network elements used in interconnection • Intelligent network services • Easy provision in a multi opr and multi-service scenario • Content can be integrated at ICE and can be pooled to all the operators connected to it • Centralized LIS with artificial intelligence, Grid surveillance and encryption/decryption for voice and internet traffic

  16. ITU-APT FDN of India Advantagescontd. • Low latency and guaranteed QoS • Reduction in Capex and Opex • Down time can be reduced with resilient multiple node architecture • FMC and Femto cell concept in multi operator environment in case of intra roaming, thus saving in spectrum

  17. ITU-APT FDN of India Implementation issues • High upfront cost • Introduction of MG in case of TDM switches with E1/STM connectivity • Introduction of SBC in case of IP based switches with GE/MPLS connectivity • In domestic networks interconnect exchange (one or two depending on the business case) at charging area level and at Metro-city level • Duplicate connectivity or connectivity through Self healing rings

  18. ITU-APT FDN of India Implementation issues contd. • Migrating TDM switches to IP based architecture • Circumventing Security risks and ensuring hassle free LI • For few years existing Interconnect regime has to continue and in parallel NGN based interconnect Exchange • Duplication till full shift to IP/ICE but better in long run • UASL operator with centralized control of MG/SBC distributed in service area

  19. ITU-APT FDN of India Implementation issues contd. • NLD/ILD operators may have centralized control at two places for geographical redundancy • By and by migration to NGN switches in the network and IP based interconnection • Integrating Voice, Video, Data & IPTV • Charging scenario will change but will be more versatile: Old Distance/Time based may be replaced by NGN based: QoS, B/W, Appln, Supplementary & VAS

  20. ITU-APT FDN of India Who will do it? • Regulator and licencer: terms to be redefined with light touch approach • All stake holders to come to gather • By incumbent operator or by other or by a separate independent operator • Management by: To be decided by all stake holders This is about ICE What about others?

  21. ITU-APT FDN of India So Perhaps in Future NGN will give • Separate access providers: DSL, Wi-Fi, WiMAX, FTTX, GSM, CDMA, 3G, 4G and xG etc • Separate: network provider with NGN core • Separate: long/short distance connectivity providers: by most Optimal Carrier Ethernet • Separate Infra: Tower, Power, BTS providers • Separate: Application Service providers • Strong Marketers with innovative ‘Tariff Products’ giving cheapest service to Public • Bring MVNO/ Virtual Operator concept AND ‘Specialized people will maintain different entities, conveniently and in the Cheapest way’
