Title: IPv6 in a Mobile Wireless Internet


1
IPv6 in a Mobile Wireless Internet

3
Heterogeneous access networks
PAN
  • Different wireless technologies for different
    scenarios PAN (e.g. Bluetooth), LAN (e.g.
    802.11) and WAN (e.g. GSM/3G/FLASH-OFDM)
  • Different characteristics for each wireless
    technology Coverage, QoS, Cost, reliability etc
  • Different IP versions IPv4 and IPv6

4
Mobility is now the Norm
Internet
WLAN
Cellular
5
The future is peer!
  • Peer to peer communication already exists in
    cellular networks
  • IP-based cellular networks inherit the same
    services and more
  • Multimedia sessions (VoIP, streaming, PTT etc)
  • Gaming
  • Chatting
  • IP-based cellular networks are all about IP-based
    multi-service networks and radio access.

6
Enabling IP-based Cellular systems
  • Scalable support for Peer-2-Peer multimedia
    applications.
  • Efficient and scalable support for IP mobility
  • Design Cellular technologies in a Packet
    friendly way.

7
Why IP mobility?

8
Requirements for IP Mobility
  • Compatibility with existing Internet hosts and
    applications
  • No modification of existing routers or routing
    mechanisms
  • Internet-wide mobility reachable everywhere
  • No modification of non-mobile hosts (i.e. TCP/IP
    stacks)
  • No modification of applications
  • Maintain connections while moving between subnets

A Packet friendly cellular networkWHY is data
different?
12
What do you want from your cellular vendor?
  • Packet-friendly radio access
  • Support for seamless mobility
  • Security
  • Same Services regardless of the access
  • Native Multicast support
  • Scalable support of various QoS levels

13
Is Power Conservation and Paging Different for
Data and Voice?
Are there also opportunities for power
conservation during bursty and/or intermittent
data sessions?

Fast Statistical Multiplexing
  • Duty cycles for data access are low
  • 4 average usage can be high
  • Fast Multiplexing Essential
  • efficient multiplexing is required on short
    timescales (ms)
  • only 8ms required to send an 1500byte Ethernet
    Frame at 1.5Mbps
  • Need to quickly switch users On/Off data resource

Statistical Multiplexing
  • The impact of Stat Mux. on user rate

FLASH-OFDM Radio Features
  • Under 50 ms RTT over the air (comparable to DSL).
  • Fast statistical multiplexing
  • Operates over a wide range of frequencies
  • Cellular range coverage of cells
  • Native multicast
  • Support for strong airlink encryption

19
FLASH-OFDM Network Features
  • Easy integration into standard IP networks
  • No synchronisation requirements between BSs
  • Mobile IP for IP mobility
  • Strong support for QoS
  • Roaming support
  • VoIP support

20
Conclusions
  • The Internet is growing even more rapidly due to
    the convergence between IP and Cellular nets.
  • IPv6 is KEY in enabling the Internet to scale.
  • The driver for successful IP-based cellular
    network are application and radio-driven.
