Outline
IP Over Wireless

• The Vision
• What we said at GSC 9 and GSC 10
• (it is just 9 months since GSC 10)
• Examples of How Challenges are Being Met

The All IP Vision (from GSC-9)
IP Over Wireless

• A Grand Vision of End-to-End IP
• The expertise in IMS (IP Multimedia Subsystem)
  resides in ATIS, and in other partners of 3GPP
• Industry has come together for an incredible
  success story for the wireless world
• How can we leverage this expertise to secure
  end-to-end support of IP for all modes of access?
• How can we proceed in the most expeditious way?

From Core Networks to Access Networks
IP Over Wireless

• IP Network Core
• The IMS (IP Multimedia Subsystem) is now accepted
  as a viable basis for the core of an all-IP
  network.

• Access Networks
• Wireline
• Wireless

IP-Based Radio Architecture Principles(from GSC
10)
IP Over Wireless

• Distributed Control Tasks (e.g., shifting
  functions from Radio Network Controller to Node
  B)
• Intelligently splitting control and user planes
  to dynamically allocate capacity based on service
  demands
• Maximize synergy between transport infrastructure
  elements (e.g., gateways, routers, etc.)
• QoS features enabled through optimized
  combination of air-interface and packet scheduler

Challenges(from GSC 10)
IP Over Wireless

• The IP over Wireless Challenges
• Spectral Efficiency
• Mobility
• QoS issues
• Efforts are underway to meet these challenges
  (from simple to more complex scenarios)

8
Examples of How Challenges are Being Addressed
IP Over Wireless

• From 3GPP Release 6 to Release 7
• VoIP is Possible (Rel. 6)
• To
• Robust Multimedia Service over Wired and Wireless
  Accesses (Rel. 7)
• .AND THAT TRANSLATES TO?

9
Examples of How Challenges are Being Addressed
(continued)
IP Over Wireless

• From 3GPP Release 6 to Release 7
• Various optimizations to the Radio Bearers and
  Signaling protocols to improve
• Latency
• Session Set Up time
• Speech Quality
• Alignment between 3GPP and TISPAN on Multimedia
  Supplementary Services

10
Examples of How Challenges are Being Addressed
(continued)
IP Over Wireless

• From 3GPP Release 6 to Release 7
• Optimizations are being looked at to support
  Wireless Gaming
• Very stringent delay requirements

11
Examples of How Challenges are Being Addressed
(continued)
IP Over Wireless

• And Later
• System Architecture Evolution (SAE) will deal
  with mobility between inter-access technologies
• In the longer term
• Early stage of consideration
