Interconnection in NGN Environment
By H C Soni Vice-President ITU-APT Foundation of India ITU-APT FDN of India NGN Standardization Colombo, April 9, 2009
2
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 NGN Standardization Colombo, April 9, 2009

4
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 NGN Standardization Colombo, April 9, 2009
5
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 NGN Standardization Colombo, April 9, 2009
6
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 NGN Standardization Colombo, April 9, 2009

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 NGN Standardization Colombo, April 9, 2009

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 NGN Standardization Colombo, April 9, 2009

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 NGN Standardization Colombo, April 9, 2009
11
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 NGN Standardization Colombo, April 9, 2009
12
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 NGN Standardization Colombo, April 9, 2009
