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

Mobility is now the Norm
Internet

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.

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

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

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

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.
