Background
• The future telecom services have the trend of
multi-dimensional characteristics.(mobile
Internet, cloud computing and other new
applications and business models)
• new requirements for networks, such as high
bandwidth pipes, mobility, real-time, interactive,
high quality, security, etc.
• The network not only needs to transport more
data efficiently, but also need to provide faster
response and service differentiation.

Flow increase pressure
• high-bandwidth video and P2P application,
operators face huge pressure on network
capacity expansion.
• The scissors difference between bandwidth and
revenue growing become wider.
• The challengers : high-bandwidth video and P2P
application, OTT services, huge pressure on
network capacity expanding. Being pipeline

The network need to become
smarter
• This network development trends require operators to
identify the user and service requirements at the network
level
– to improve network efficiency and value through intelligent
resource scheduling and network traffic management.
•
This kind of network can be refer to as High Intelligent
Network (HIN) to reconstruct the traditional simple
network pipe into a ‘Smart Pipe’
• The technologies component for HIN include converged
resource policy control system, Deep Packet Inspection
(DPI), intelligent traffic management/QoS mechanism,
User Data Convergence(UDC), etc.

Characteristics of HIN
• Network status aware with DPI and multidimensional perception
• User self-assignment of network resources
• Network coordination between wireless and
fixed network
• On-demand service quality assurance and
service differentiation
• Intelligent traffic management/QoS assurance

Target of High Intelligent
Network
• High Intelligent Network (HIN) provides network
transport resources service based on user and
application requirements.HIN can provide users
with flexible mechanisms to enable users to
request specific network resources and
dynamically adjust the requirements.HIN can
provide control interface to network applications,
enable applications to request required resource
and service level on demand.

Highlight of Current Activities
• ITU-T SG13, 3GPP, BBF and CCSA have a
strong intention on investigation and
standardizing High Intelligent Network related
technologies.
– ITU-T SG13 : NGN& Future Network, SUN (Smart Ubiquitous
Networks)
– 3GPP: Enhanced PCC for FMC (WLAN,H(e)NB)
– BBF: Interworking between Next Generation Fixed and 3GPP
Wireless Access, Broadband Policy Control Framework (BPCF)
– CCSA: The architecture of High Intelligent Network;The
converged fixed and mobile network policy control system

Strategic Direction
• Make a resolution of HIN including:
– The requirements for High Intelligent Network
– The system architecture of High Intelligent Network
– The typical application model and efficient networking scenario.
• Key considerations:
– The architecture of HIN is divided into control layer and network layer to
enable the separation of network control and data transport,
– In addition to the exiting AAA and network management systems, the
control layer consists of unified authentication system, traffic perception
analysis system, policy control and traffic scheduling function. By
interact with the service platforms, control layer can provide network
status and user traffic information to applications, and collect resources
requirements from applications.
– The converged fixed and mobile network policy control system
– Interactive between High Intelligent Network and service layer network

Strategic Direction
• Our target should be better focused on the application
model and networking scenario in order to differentiate
with other standard body.
• ITU-T SG13 has setup a study items on Smart
Ubiquitous Networks (SUN) in July 2011. SUN is IPbased packet networks that can provide transport and
delivery a wide range of existing and emerging services
to people and things.
• 3GPP and BBF have agree developing the converged
fixed and mobile network policy control standards based
on PCC (Policy and charging control) architecture.
• Possible cooperation with major standard body.

Next Step Suggestion
• Based on the above discussion, we
propose to start a new working item about
resolution of HIN
