Q12
•Evolution towards
integrated multi-service
networks and interworking
Role of Q.12/13
Motivation
The rapid growth and the embedded base of legacy telecommunications
networks have necessitated a strategy of evolution towards integrated multiservice networks which connect to enterprise and home networks. Due to
popularity of the IPTV and transformation of networks to NGN it has become
necessary to include study of home networks. Thus the focus of this Question
will include activities related to IP television (IPTV) and home networks. This
Question will address items such as:
determination of how best to carry narrow-band and broadband services
of a fully integrated IP-based network across non-IP based networks (e.g.
FR and ATM);
description of interworking of services, including definition of protocol
requirements;
interworking of services between home network operator administered
networks.

Q24
•Service scenarios,
deployment models
and migration issues
Role of Q.24/13
Motivation
As NGN and Future Networks scope covers wide areas of network, a set of
promising service scenarios and deployment models of NGN and Future
Networks are very useful to accelerate the NGN and Future Networks
deployment. All the scenarios should be initiated from the user point of views,
which would be described as use cases.
At the same time, operators of existing telecommunication networks have
expressed concerns connected with the necessity of full replacement of their
network equipment when migrating from traditional telecommunication
networks to NGN and Future Networks.
For Future Networks, more and more new technologies will be introduced, e.g.
Cloud Computing, IoT, etc. The architecture and deployment of Future
Networks will be probably largely different from the existing
telecommunication networks. Foregoing requirements will be still available
when existing telecommunication networks or NGN migrate to Future
Networks.
Role of Q.24/13
Tasks
Develop documents on NGN and Future Networks service scenarios
including emerging services and converged services.
Develop documents on NGN and Future Networks based IPTV service
scenarios that converge traditional broadcasting services and
telecommunication services over the NGN and Future Networks
environment.
Develop documents on service scenarios of use cases and 3rd party
services for ubiquitous environments.
Develop documents on migration scenarios to NGN and Future
Networks.
Develop documents on decision factors for selecting migration scenarios
and migration criteria through analysis of the scenarios.
Continue documents currently under way.
Documents produced under this Question will normally be published as
Supplements or will progress through, or in coordination with, other related
Questions.

MM mechanisms supporting
multi-connections for multiple access
technologies
Role of Q.9/13
Motivation
•Different types of network connections may provide users
with different user experiences, such as broad bandwidth, low
time delay, and high security. The main purpose of multiconnection is to federate all means of access technologies in
order to access the network ubiquitously (from everywhere
and at any time), benefit from different advantages of
multiple access technologies, and help us to provide better
user experience
•Users and operators may benefit from harmonization of
multiple connections, such as efficient utilization of network
resources, load balancing, reliability of connection and
continuity of services, etc
Role of Q.9/13
Tasks
•Explore the scenarios and the policies for multiple connection
harmonization in mobile networks utilizing fixed and mobile accesses
•Identify and study enhancements to existing Recommendations related to
service requirements for the harmonization of multiple connections for
multiple access technologies.
•Develop high-level network architecture enhancements to support the
harmonization of multiple connections for multiple access technologies.
•Study Multi-connection Technical Issues: Routing mechanism、Multiconnection based services such as Streaming, conference etc、
•Study UE functions in multi-connection，coordination among multiple
connections.
•Identify which MM mechanisms are required to provide service continuity
through multi connection in multiple access networks and at the same time
their effect to provide unawareness of such functions to multimedia services.

Towards the ultimate migration to interoperable network,
there is an industry requirement to provide global roaming
and seamless mobility for the users of different access
technologies and/or different operators.
The work of Mobility Management and Fixed Mobile
Convergence includes all aspects required in terminals,
customer networks, access networks (both wired and
wireless), core networks and application services.
Role of Q.22/13
Tasks
•Develop the functional requirements for mobility management
capabilities for both IMT and NGN.
•Develop the architecture (interrelationship) and definition of the
functional entities, information flows required to provide mobility
management capabilities for both IMT and NGN.
•Allocate the functional entities to physical entities in order to determine
which interfaces can use existing protocols or enhancements to existing
protocols and which interfaces need protocol development for mobility
management capabilities for both IMT and NGN.
•Identify and study the applicability of convergence related evolving IMTstandards in the context of the NGN architecture and FMC requirements
and document these.
•Identify and study architectural and network interface issues relating
to FMC specific functions in the overall NGN architecture, and document
these.

Summary

WP 4/13 is addressing QoS and security issues in NGN and beyond

A set of Recommendations has been developed
 Y.2111 specifies RACF—the central enabler for NGN QoS
 Y.2701 and Y.2702 set the basic security requirements for NGN
 Y.2720 provides a holistic view of IdM in NGN and lays the foundation for
further development

Ongoing studies include
 IdM requirements and mechanisms, and securing mobile financial
transactions (expected to be complete at this meeting)
 Security requirements for DSN (jointly with Q.19/13)
 Enhancements of RACF in support of mobility, and coordination with network
performance management and CPN resource management

Framework of Object Mapping using IPv6 in NGN
 This Recommendation describes requirements and mechanisms
for object mapping using IPv6 in NGN.
 Basic concept and requirements of object mapping using IPv6
 Mapping architecture and relationships between identifiers
 Mechanisms for object mapping using IPv6
 Direct mapping vs. Indirect mapping
 Direct mapping: An object at application layer is directly
reachable to host entity at Point of Attachment (PoA) which IP
is terminated.
 Indirect mapping: An object at application layer is remotely
reachable through non-IP interface to host entity at PoA which
IP is terminated. An object is located outside of physical
network attachment which IP is terminated.

Role of Q.21/13
Question 21/13 – Future networks
Future network - A network able to provide revolutionary
services, capabilities, and facilities that are hard to provide using
existing network technologies (ITU-T Q.21/13 Jan. 2009 meeting
report ).
 FN is the network of the future: made using Clean-slate Design.
It should provide futuristic functionalities beyond the
limitations of the current network including Internet (IP).
FN provides mechanisms that benefit every participant as much
as they contribute.
Backward compatibility may or may not be required.
[Note] : Clean-slate approach is understood as a design principle, not
deployment aspect.
Focus group on Future Networks

The group was established in 2009. The objectives were to gather new
ideas, identify potential study areas, describe vision with a targeted
timeframe, and suggest future actions.

In 2009 and 2010, FG held eight meetings led by Mr. Takashi Egawa,
NEC, Japan, and collocated with FN-related academic events. Project
descriptions in 135 pages summarizes the research activities.

As a Future Networks vision, FG has found new requirements for
networks, and identified four objectives (service-, data-,
environment-, and social and economic awareness), and twelve
design goals. It is assumed that the target date for trial services and
phased deployment of FNs falls roughly between 2015 and 2020. The
document becomes a good candidate for the first Recommendation
(Y.3001) on Future Networks.

FG
