Customer Manageable NGN Services - 1

Backgrounds

Explore the IT-based New Business Markets using network
resources and capabilities toward personalized and
ubiquitous worlds



Many virtual network operator, Virtual service providers/agent
Application provider/broker, Contents provider/agent
Approaches



Identify the relevant network capabilities to be open
Standardize the Interface to open network resources and
capabilities (i.e., Open API, Agent/Broker, VPN, etc.)
Develop the specific scenarios and protocols (not exhausted)

Customer Manageable NGN Services - 2

Consideration Issues

The existing NGN control/management concepts are
manageable from users ?




Where are the middleware functions to be open to User ?




IMS control over GGSN/SGSN
IMS-based Softswitch over IP Transport
RACS over IP Access and Transport
Common naming/addressing/identification and directory
Common security, and charging/billing structure
Common profiles on services, applications, and subscriber
The Open APIs are really open ?

Digital Multimedia Broadcast (DMB) and
IP TV Services

Backgrounds

DMB is one of key driver of NGN as well as VoIP



NGN converge with Digital Broadcast and TV
The existing NGN Control Architecture including IMS is not enough
Study Issues

Functional Locations of network elements for DMB and IP TV




Network elements including MCU for access, process, storage, security, and
subscriber management, etc.
especially using FTTH/PON, Wireless LAN/MAN, Terrestrial broadcast
antenna, and Satellite, etc.

Home and Ubiquitous Network Applications
over NGN

Backgrounds



Digital Home and Ubiquitous Sensor Applications will be a
emerging market
No considerations on the current NGN network architecture
including control and management
Study Issues



Identifications of Home Equipments and Ubiquitous RFID
Boundary and Relationship between Home Equipments
including Home gateway and network elements

Delivery Time Guarantee Service For Emergency

Backgrounds




Short data or SMS services for emergency situation
Migrate the Emergency service within NGN domain
How to implement some parts of Y.1271 within the NGN scope
Discussion Issues

Preemptive Priority are needed on


DiffServ-based Delivery
Session-based Delivery


The existing session-based NGN could not support these applications because of
long session establishment time
Service Architecture and QoS Provisionings


Service requirements for QoS, security, and location confidentiality, etc.
Scenarios for protection and redundancy

Harmony between E.164 and IPv6 Address

Backgrounds




National administrative boundary on IPv6 address structure
Easy binding between the Existing PSTN/Cellular number
and IPv6 address
Set up the naming/numbering/addressing plan at the NGN
Infrastructure
Approaches


Integration of Telco-based services and IP-based applications
within the NGN worlds
NGN addressing structure provide Easy Binding of E.164
number and the IPv6 address
