Background for Q.2/SSG
• Convergence of fixed and wireless networks and ultimately migration
to interoperable and harmonized network architectures to provide
services transparently to the users across different access arrangements
is becoming an industry requirement.
• Along this line, the rapid growth of IP ‘fixed’ networks and the support
of mobility over these networks (e.g. Mobile IP, SIP mobility, etc.)
have pushed for the emergence of new IP based mobility protocol
solutions
• Due to all the above reasons, the study of these protocols is essential to
be able to address properly the evolution towards a common mobility
management protocol for the NNI.

Q.2/SSG – Mobility Management protocol
Question 2/SSG asks:
 What new mobility management signalling application
protocols, or enhancements to existing protocols are
needed to provide seamless global roaming for IMT-2000
future Capability Set services that will include:
–
–
–
–
voice,
high speed packet data,
multimedia, and
IP-based services,
– this Question provides the SSG’s expertise on mobility
management

Q.2/SSG – NNI Mobility management protocol
Q.2/SSG task objectives include:
• identify differences between current mobility protocols and determine
if any new protocols or enhancements are needed for the Common
NNI (Mobility Management) to support the features identified and
Global roaming between networks.
• Propose protocol requirements and enhancements needed to these
protocols with respect to the above considerations. If enhancements
are identified, it is important to interact with the proper standard
bodies to complete the work.
• Establish co-operative relationships
• - within ITU (ITU-T, ITU-R, ITU-D)
- externally with other SDOs, etc.

Linkages on Harmonization outside ITU
Formal Standards Development Organizations (SDOs)
•
•
formal standards are being referenced through SDOs (TIA, ETSI, TTA, etc)
existing relationships with ITU is effective
3G Partnership Projects (3GPP and 3GPP2)
•
•
for both 3GPP and 3GPP2 an established relationship exists at the SSG level
through the SSG Chairman
relationships are being developed at the working level
Internet Engineering Task Force (IETF)
•
•
SSG studies may identify new/modified protocol requirements
possible future interaction with IETF on protocol requirements

Collaboration within ITU
ITU-T
• SG-13:
Interaction to ensure consistency with areas under SG13 responsibility
such as NGN (Information sharing in Geneva, November 2002)
• SG-11:
Similar synergy on NGN studies
(There was discussion at the SSG’s Ottawa meeting in May 2002, and a Liaison Statement
to SG-11 from Q.7/SSG addressed mobility across fixed and mobile networks)
• SG-16:
Interaction on Multimedia aspects of mobility studies
