“An Industry Wide Solution For Enabling Global IP Service Interconnect”

Confidential 3

What’s New About Interconnect / Interoperability?

Support Multiple Services & Applications– Not just voice– Multiple networks and access points– Different points are using different technologies – Wide range of devices / wide variety of capabilities– Multiple identities / destinations– Number Portability and data correction

– Not Just In Future – Growing Issues Now

ENUM Designed For This Complexity– NAPTR URIs for each service type

….E2U+SIP, E2U+MMS, E2U+SMS, …

– Plus NAPTR service tags to identify any additional service capabilities of the user

– Usable for NP lookups as well - bridge to future

Today Industry Must Solve Scalable IP Interconnect

Promise of IP Networks– Lower Costs / Reduce OPEX– Enrich current services – Launch New Service / Add New Revenue

Operator Deployment Strategy– Build “Own Network” First– Initially Rely On PSTN For Interconnect– Migrate To Native IP Interconnect– Test IP Interconnect via Bilaterals

No “Pure” IMS Models Today– Carriers Networks Are Not All The Same

• Varied IMS, NGN & Hybrid Networks• Most Interconnect Is Service Specific To Date

Challenges– Economics & Organization of Global System– Utility Now, Clear Path To Future

• Now - Match TNs w/ Operators - Number Portability • Emerging - Discovery of IP Service Gateways

– Business & Network Realities Require ‘Hubbing’– Must Enable Real Interconnect Models - Carrier/IPX– Must enable rich services interoperability

No port correction by International network leads to extra costs– May require port correction at donor network by dip or onward routing => extra cost– Recipient network rating => potential for extra cost with higher terminating feesResults in sub-optimal use of on/off-net termination contract bundles
