Summary - Introduction
  • 3G does not have standards-defined services and
    applications
  • 3G will enable Wireless Service Providers to
    bring new services to market
  • Many services will co-exist within wireless
    networks and even during an end users session
    bandwidth must be efficiently managed and
    tailored to specific applications
  • Market success requires more than technology, yet
    technology will be a key enabler
  • Wireless Network Operators will need to provide
    the killer service environment
  • Wireless Service Providers Competitive Advantage
    -- the provision of an open service environment
    where content providers and applications
    developers can rapidly develop, provide,
    customize and deliver services to meet end users
    needs
  • Efficiently designed services will compete with
    wireline services

25

    fully supported in the Radio Access Network
    associated with all three 3G CDMA modes.
  • Supports functionality based on synchronous
    operation such as location calculation, etc.
  • Supports seamless handoff between the harmonized
    DS and MC including IS-95 for ANSI 41 and the
    equivalent to this for UMTS/GSM.
  • Minimize the complexity of dual-mode and
    muti-band terminals and equipment.

Harmonized G3G Technical Framework
  • Protocol Structure for Implementing the Modular
    Concept
  • Hooks any functionality that is specified for
    the initial release of the standards so that the
    extensions needed to satisfy the requirements

Summary - Standardization for IMT-2000
  • 3G system shall be evolved from 2G system and
    different countries are standing in different
    positions according to 2G systems deployed
  • There are multiple systems for IMT-2000 and
    multiple paths to 3G it is important to choose
    the best way to reach to the goal
  • There are many standard bodies in the world and
    many companies in each standard body.
    Harmonisation between these companies is very
    important even though these companies are very
    competitive.

Summary
  • 3G does not have standards-defined services and
    applications but will enable Wireless Service
    Providers to bring new services to market
  • There are multiple standards for IMT-2000 and
    multiple paths to 3G it is important to choose
    the best way to reach to the point
  • The potential of mobile radio technologies,
    including IMT-2000, help developing countries
    bridge the gap between their communication
    capabilities and those in developed countries
  • We will cooperate with any other countries and
    companies for successful deployment and services
    of IMT-2000
