Summary
Can We Ignore NGN?
Market
POTS is still the primary revenue generator.
„ The most lucrative users still remain in POTS.
„ POTS is still popular because it is widely available and affordable.
„
Network Platform
NGN is a reliable and stable platform for network transformation.
„ It has passed through 5 years of simulation, testing, trial and
upgrade.
„
Differentiated Services
Flexible platform to create and provision a broad array of VAS.
„ Various exciting NGN applications are ready to market.

Summary
Can We Ignore NGN?
Business Planning
„
„
„
The risk of migration has been thoroughly assessed and minimized.
NGN network transformation is supported by successful commercial
business case from established telecoms.
NGN migration guarantee smooth service continuity and the subscriber
data profile can be fully retained.
Competency
„
„
„
Reduce the CAPEX and OPEX of the network.
100% inherit the traditional PSTN’s basic and supplementary services.
Innovative voice and non-voice services ensure higher quality of experience
¾ NGN is the most appropriate choice to resolve difficulties currently
confronted by operators.
¾ Network operator’s investment in NGN will be protected in IMS
smoothly.
