ITKS540 Introduction to mobile technology and business

Jani Kurhinen

Fall 2008

University of Jyväskylä


Next generation networks

Next Generation Networks

  • Not a networking technology

    • Concept for unifying network services.

  • Need to converge and optimise the operating networks

  • Expansion of digital traffic

    • increasing demand for new multimedia services,

    • increasing demand for mobility...

Next generation networks1

Next Generation Networks

  • Work is carried by ITU-T’s NGN-Global Standards Initiative (NGN-GSI)

  • NGN-GSI Objectives and Goals:

    • to address the market needs for NGN standards

    • to produce global standards for NGN

    • to further strengthen the ITU-T’s leading role amongst the groups in NGN standard work

    • to keep visibility of the work spread between different technical groups in ITU-T

Next generation networks2

Next Generation Networks

  • ITU-T activities:

    • architectures,

    • interface specifications and

    • implementation guidelines.

University of Jyväskylä


Next generation networks3

Next Generation Networks

  • Packet based connectivity

    • A packet is a small piece of data with payload and control data.

  • QoS enabled

  • Services independent from technology.

Evolution of networks to ngn

Evolution of Networks to NGN

  • Interoperability with existing networks.

  • Continuation of existing networks.

  • Enabling the implementation of new capabilities in parallel.

  • Evolutionary process

    • Not all networks will start from the same point.

University of Jyväskylä


Quality of service

Quality of Service

  • The basic criterion is subjective user satisfaction.

    • speed, accuracy, reliability, and security

  • Parameters that can be directly observed and measured

    • at the point at which the service is accessed.

    • both sides: users and network providers.

University of Jyväskylä


Interoperability

Interoperability

  • NGN will involve a broad series of protocols

    • service and network levels

  • Interoperability between different systems and networks.

University of Jyväskylä


Security

Security

  • Security issues interrelate with

    • architecture,

    • QoS,

    • network management,

    • mobility,

    • charging and payment.

University of Jyväskylä


Generalized mobility

Generalized Mobility

  • Users and devices have the ability to communicate and to access services irrespective of change of location or technical environment.

  • Service availability may depend on several factors:

    • including access network capabilities, service level agreements between the user’s home network and visited networks, etc..

University of Jyväskylä


Generalized mobility1

Generalized Mobility

  • Ability to communicate from various locations using a variety of terminal equipment

    • with or without service continuity,

    • while in transit,

    • while changing access means.
