Current Drives of Change

• Multimedia, mobile personal computing and WWW dictate the value of networked services

• New access network technologies (xDSL, 2.5/3G/4G, WiFi, WIMAX, FTTH) allow higher level of demands enter core network

• Explosion in available bandwidth due to optical transmission

• Data dominates voice so new network technologies must rather be designed for data hence packet-based backbone

Final Goal : NGN roadmap for Thailand Ongoing Activities to Promote Meaningful NGN in Thailand

– NGN Testing/Trial Use Center in Phuket– NGN Forum Thailand – TRIDI– NTC initiatives in educational applications of NGN

NGN Testing/Trial Use Center in Phuket

Run by Chulalongkorn U.

Introduction

• Need for testbed to resolve common critical issues in migrating from legacy networks to IP networks

• Comprehensive NGN pilot test program conducted in Thailand.

• Phuket has been selected as our test city.

PHUKET

Objectives

• Test and evaluate the migration to IP networks

• Study the feasibility (both technical and economic) of the migration to NGN and obtain effective investment strategies

• Refine the roadmap for future migration to NGN

Cooperations

• Industry is invited to join in and bring equipments and applications to test/evaluate within this project.

• Benefits e.g. compatibility and inter-operabilitytesting with other systems and applications

• NTC subsidy in the transportation of equipment within the country and the import taxes as well as necessary basic test infrastructures.

Collaborators

Scope of NGN Testing / Trial Use

1) NGN Wireless ACCESS: Wimax

2) NGN Wired ACCESS: FTTx

3) NGN CORE : IMS

4) End-to-end NGN : VoIP QoS

5) NGN Applications

Remark: When Mobile Station switches to the other network, It has to acquire new IP address from new network. There will be an effect to the application that requires constant data transmission but for theapplication likes web browsing that doesn't always have an effect.We called this kind of switches network "loosely couple internetworking”.
