NETWORK TRANSFORMATION TO NGN (2)
Approach……
Gradual transformation (Keep & Grow):
9 Implementing gradual and scaled process by reasonably
integrating new platform while keeping the legacy network
components (i.e exchanges) to their useful lifetime.
9 To enable new network to co-exist with the legacy PSTN for
a reasonable time period before fully migration to NGN.
9 Cost effective approach: leaves PSTN components to be
removed gradually by replacing with the NGN/IMS
compliant nodes on basis of their obsoleteness.
