NGN provides a converged services based on the open common service platform ,common IP core network combines various access networks and user services.
Legacy service networks were dedicated and isolated network with service specific signaling and routing for service connection
NGN service networks will have common IP corenetwork and provide a nomadically accessible common IP application regardless of a specific access link and user devices.

Link/physical Layers- Services Independent link layer - Inter-connect network layer nodes- provides point to point virtual/physical
circuit to network layer nodes
Transport and Network Layer- Services dependent transport/network layer - Differential services network- Provides routing and switching services for the user/signal IP datagram
Services and Control layer- Provides user contents, connection servicedepend on each services
- provides session control, AAA etc.- provides network QoS, bandwidth control

1. What is the NGN ? Layered Open IP Network
Common core network will be IP network over the various types of transmission link layers . All user and signaling traffic will be transported and routed by the same IP data packets form.
7/222005, LGE Proprietary
- All Network Equipment support the same IP network layer protocol suitesindependence from the lower link layer protocol types.
- All the upper protocol layers over IP layer interact only with the destination peer entity without any interaction of the intermediate node entity.è Easy implementations and installations of user
services and applications
