Highlights from Presentation 1
“ITU-D inter-sector activities”

All Sectors of the ITU are active in promoting IMT-2000
 ITU-R WP 8F & ITU-T SSG: Handbook: Deployment
of IMT-2000 Systems; in addition to technical work
 ITU-T SSG: 2 prior IMT-2000 Workshops; seminars
 ITU-D: World Telecommunication Development
Conference , Istanbul, 18-27 Mar 2002

Resolution 43 (“Assistance in Implementing IMT 2000”)
ITU-D Q.18/2 (“Strategy for migration of mobile networks to
IMT-2000 and beyond”): Mid Term Guidelines
Promotion of IMT-2000, especially in "developing" countries
Workshop on NGN, Geneva, 9-10 July 2003
Highlights from Presentation 2
“Mobile Access Issues”


TD-SCDMA: ITU recognized IMT-2000 radio technology
Status: successful Network Acceptance tests


TD-SCDMA Alliance (vendors) and Forum (vendors and
operators): local and global membership

high speed (125km/hr), long range (>20km) video
transmission; data to 384 Kbps
supported by 3 Chinese Ministries (SDPC, MII and MOST)
focus: further technology, promote TD-SCDMA
China mobile market has overtaken USA
TD-SCDMA technology will be major player in providing a
cost-effective evolution path from to IMT-2000

“Looking Beyond Network Boundaries”




5/31/2016
People value multimedia, security, personalization,
mobility
Simplify the network: eliminate boundaries & distinctions
To make real: blend user devices (PC, PDA, phone), use a
unified user profile, a single address to reach the user
Operator becomes ultimate single point of contact for user
 Single phone number/address used to contact a person
 Receiving party decides where to answer the call:
mobile phone / PDA / PC / wireline phone

1: huge multimedia traffic handling
2: accommodate diverse wireless access
3: advanced mobility management
4: seamless/ubiquitous services
5: applications services support
Must make mobility a base capability
Evolve to Plug ’n’ Play diverse radio technologies on a
converged Mobile Network/Internet

Overview of issues in the session


5/31/2016
IMT-2000 promises a great deal: today, as it evolves, and
in “systems beyond”
 promotion is essential to creating awareness,
transferring knowledge, global deployment
 radio technologies will evolve, improve
 network must be able to deal with heterogeneous access
and user devices: seamless user experience
 operator will be ultimate single point of contact for user
 mobility must become a base capability
Transformation of the network is key
Workshop on NGN, Geneva, 9-10 July 2003
Recommendations


5/31/2016
Increase focus on the evolution of the “core network”
 mobility as a base capability
 single phone number/address to contact a person
 blend user devices: mobile phone / PDA / PC / wireline
phone
Transform the network
 dynamic packet/optical network
 secure multimedia services
 ubiquitous broadband
 integrated functionality
Workshop on NGN, Geneva, 9-10 July 2003
Follow-up actions



5/31/2016
Solicit greater operator involvement
 set the requirements for the seamless end user service
experience
 ultimate single point of contact for user
Increase focus on access independence
 support heterogeneous radio access technologies
Seamless user experience: increase focus on convergence
 wireline and wireless networks are converging
 increase focus on internetworking, internetwork
mobility management
Workshop on NGN, Geneva, 9-10 July 2003
Conclusion



5/31/2016
Core Network is an essential and major component for
providing services, sometimes overlooked due to the
emphasis placed on radio technologies and spectrum issues
Converged Core Network will evolve to become access
independent, provide mobility as a basic capability
Greater attention needs to be paid to the long term (NGN):
 where are we going
 how are we going to get there
 how do we leverage the existing infrastructure
