Interconnection in NGN Environment By H C Soni Vice-President ITU-APT Foundation of India ITU-APT FDN of India
Present Scenario • Separate Network for Basic & Mobile (Voice) and for Data • Huge growth- 15 Million connections in one month • Increasing numbers of Application developers, Operators and Traffic • Every operator to have interconnection with each other and with many NLD and ILD operators ITU-APT FDN of India
When interconnection at one place BS1 BS2 BS3 ILDO1 NLDO1 ILDO2 NLDO2 MO1 MO2 MO3 ITU-APT FDN of India
Challenges • High interconnection cost • Connection at different levels and at many places • Complex routing at every point • Huge requirement of ports and their cost • Physical provisions at different places causes delay and need more capacity • Sub-optimal utilization of resources ITU-APT FDN of India
Challenges contd. • Inefficient handling of calls • High operational cost for managing inter operator settlements • Inter carrier billing • Complexity in settlement in Interconnect usage charges • Increase in CAPEX and OPEX ITU-APT FDN of India
Solution:Next Generation Networks • Open and Fragmented Architecture • Best breed of products • Better Performance • Required Quality of Service • Efficiency in inter working Thus NGN interconnect Exchange can be best for inter connecting ITU-APT FDN of India
IP based Interconnect Exchange BS1 BS2 BS3 ILDO1 NLDO1 INTERCONNECT EXCHANGE ILDO2 NLDO2 MO1 MO2 MO3 ITU-APT FDN of India
Advantages • Network simplicity leads to reduction interconnection cost and port charges • Simple network interconnection using GE or OFC as per ITU-T G.653 • Reduction in number of links • Simplifies digit analysis for all inter operator and long distance calls from the switches connected to it • Simplification in carrier selection function • Less time consumption in provision of PoIs • Reduce Capex and Opex ITU-APT FDN of India
Advantages contd • Inter carrier billing • Less connection: less disputes • Clearing house function • Inter operator charging based on GOS, Content and network elements used in interconnection • Simplicity in terms of interconnect • Intelligent network services • Easy provision in a multi operator and multi-service scenario ITU-APT FDN of India
Implementation issues • Introduction of MG for interconnection with TDM switches with E1/STM connectivity • Introduction of SBC in IP based switches with GE/OFC G.653 • Duplicate connectivity or connectivity through Self healing rings • Migrating TDM switches to IP based architecture • In domestic networks interconnect exchange at charging area level and at metro level- Regulator to come into play for intra-charging area carriage charges ITU-APT FDN of India
Implementation issues contd. • For few years existing Interconnect regime should continue • In parallel IP based interconnect Exchange • Regulator to draw the rules of the game • UASL operator with centralized control (with DR) of media gateways distributed in service area ITU-APT FDN of India
Implantation issues contd. • NLD/ILD operators may have centralized control at two places for geographical redundancy • Integrated operators may have common control points • By and by migration to NGN switches in the network and IP based interconnection • Integrating Voice video and Data ITU-APT FDN of India

Who? • Regulator and licencer: Rules of the game • All stake holders come to gather • By incumbent operator or by other/separate operator • Management by: To be decided by all stake holders ITU-APT FDN of India
