ITKS540 Introduction to mobile technology and business

1. ITKS540 Introduction to mobile technology and business Jani Kurhinen Fall 2008 University of Jyväskylä

2. 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... University of Jyväskylä

3. 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 University of Jyväskylä

4. Next Generation Networks • ITU-T activities: • architectures, • interface specifications and • implementation guidelines. University of Jyväskylä

5. 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. University of Jyväskylä

6. 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

7. 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

8. Interoperability • NGN will involve a broad series of protocols • service and network levels • Interoperability between different systems and networks. University of Jyväskylä

9. Security • Security issues interrelate with • architecture, • QoS, • network management, • mobility, • charging and payment. University of Jyväskylä

10. 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

11. 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. University of Jyväskylä
