T8: Technologies for All-IP Wireless Networks from 3G to 4G
Next Generation Networks

As 3G wireless systems are deployed worldwide, significant efforts have been underway in the research community and the wireless industry for “4G” wireless systems. The ITU (International Telecommunications Union) envisions 4G systems to support data rates up to 100 Mbps for highly mobile users, and up to 1Gbps for slow-moving users. It has defined the requirements for 4G wireless systems, which is also called “IMT-2000 and Beyond”, and is defining the networking aspects of the 4G systems which include “wireless Internet, convergence of mobile and fixed networks, mobility management, mobile multimedia functions, internetworking, interoperability and enhancements to existing IMT-2000”. It is widely anticipated that 4G radio spectrums will be allocated in 2007, standards will be ratified in 2008, initial 4G systems will be deployed in 2010, and broad development of 4G systems will occur by 2015.

However, significant challenges still await solutions. Many of these challenges are in the areas of end-to-end 4G networking, network and application layer protocols and algorithms, and technologies for supporting 4G applications and services. This tutorial is intended to address state-of-the-art technologies necessary for building a practical all-IP wireless network. The tutorial will focus on IP layer and upwards. Evolution of technologies from 2G, 2.5G, 3G to 4G will be discussed. Challenges in realizing applications like mobile IP telephony and streaming multimedia over wireless IP networks will be elaborated. The tutorial will also cover various mature and on-going IETF protocols including signaling, registration, configuration, dynamic address-binding, location management, AAA, quality of service, broadcasting streaming content, and integration with legacy cellular systems for both IPv4 and IPv6 based networks. Practical experience of the presenters in building a prototyping indoor-outdoor testbed emulating mobile wireless Internet in conformance with 3GPP and 3GPP2 architecture will be shared.

Scope and Objectives:
This tutorial will survey several topics related to all-IP wireless networks from 3G to 4G. Although this tutorial will cover various topics, it will be presented in an integrated approach such that audience can learn how to build a completed system.

• Introduction to wireless communication and mobile networking
• Current industry standards update (3GPP, 3GPP2, ITU, IETF)
• Mobility management
• Signaling issues in mobile networking
• AAA and security
• QoS support in wireless networks
• Mobile wireless applications
• Conclusion
