Legacy service networks were dedicated and
isolated network with service specific signaling
and routing for service connection
NGN service networks will have common IP core
network and provide a nomadically accessible
common IP application regardless of a specific access
link and user devices.

1. What is the NGN ?
NGN Service Network Configurations
- Common IP core transport network will be logically separated depend on the QoS
and Services
- Various heterogeneous access network will provide a connection for various types
of application traffic over the same homogeneous IP packet network protocol
- AG will terminate the access specific link interface protocol for terminals

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

1. What is the NGN ?
Peer-to-Peer Interactions
- All Network Equipment support the same IP network layer protocol suites
independence 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.

2. Enhanced Legacy call Application
IMS Video call
- Legacy WCDMA and CDMA system provides video call only between the
homogeneous type phones
- IMS core network supports flexible applications and independence from
the access technologies.
- This is accomplished in part via the separation of access, transport and control

MSC server and MGW support the efficient radio spectrum usage for voice
comm.
- No packet header over head compare to end - to - end VoIP
Support an harmonized solution for the PSTN evolution to IP network
- MSC server directly signals with the MGC in the PSTN using MEGACO
- MS talks with the residential subscriber through the BSC/SDU and RGW
over the IP network
