NGN Vision
o Secure and Convenient network featuring both the existing Fixed-
Telephone Network and IP Network
o IP-based network enabling
— Guaranteed QoS
— provisioning of seamless fixed & mobile services
— provisioning of broadband Internet access, IP telephony, multicast
communication for video distribution, bi-directional video (data)
communication, & Ethernet services
o Layered structure model for future technological and service flexibility
o IMS-compliant service control functions
o Open network （Network interface disclosure）ensuring security and
interconnectivity with other carriers and ISPs.

NGN Core Network
o Basic principles
• Access independent Control Layer (IMS, AAA, mobility
management, Policy Control & Charging, QoS, etc.)
• All non-legacy IP broadband access systems connected to the
core through the same interface (S1)
• Access system independent Multiservice Edge Node
• Inter-system mobility management integrated in IP core network
• Common IP/GBE metro access network
• Single IP core network transport
o Customers’ needs:
• Seamless experience across technologies
• One profile for multiple services

‡ IMS based control become
the trend
‡ Clear Separation of Service
stratum and Transport
Stratum
‡ QoS control cover both
access and Core network.
‡ Open API.
‡ IPTV and stream service are
the killer applications.
‡ Most protocols are covered
and developed.
‡ Protocol related to Resource
control are the hot areas.
‡ NASS and RACS related
standards are the hot areas.
‡ IMS is the main control
mechanism.
‡ Unified User database.
‡ Support variant access
technologies including
3G and WIMAX.
‡ FMC
‡ End to end security is
guaranteed.
‡ Protocols developed
into mature stage and
are ready to use.
‡ Requirement and
functional architecture.
‡ Mainly support
ADSL/WLAN access
‡ QoS covers access network.
‡ Mainly support VOIP
service.
‡ PSTN/ISTN evolution.
‡ PSTN/ISTN simulation and
emulation services
‡ Interworking with
PSTN/ISDN
‡ Only few protocols are
developed.
NGN trials
Limited deployment
‡ Super 3G is supported
‡ FTTH is supported
‡ Service data profile is
separated from transport
data profile
‡ IMS evolve to All IP
network?
True Converge?
