2GSC: Standardization Advancing Global Communications
Outline
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
IP Over Wireless
3GSC: Standardization Advancing Global Communications
The “All IP” Vision (from GSC-9)
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?

IP Network CoreThe IMS (IP Multimedia Subsystem) is
now accepted as a viable basis for the core of an all-IP network.
IP Over Wireless
6GSC: Standardization Advancing Global Communications
IP-Based Radio Architecture Principles(from GSC 10)
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

7GSC: Standardization Advancing Global Communications
Challenges(from GSC 10)
The IP over Wireless Challenges Spectral Efficiency Mobility QoS issues
Efforts are underway to meet these challenges (from simple to more complex scenarios)
IP Over Wireless
8GSC: Standardization Advancing Global Communications
Examples of How Challenges are Being Addressed
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?
IP Over Wireless
9GSC: Standardization Advancing Global Communications
Examples of How Challenges are Being Addressed (continued)
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
IP Over Wireless
10GSC: Standardization Advancing Global Communications
Examples of How Challenges are Being Addressed (continued)
From 3GPP Release 6 to Release 7
Optimizations are being looked at to support Wireless Gaming
• Very stringent delay requirements
IP Over Wireless
11GSC: Standardization Advancing Global Communications
Examples of How Challenges are Being Addressed (continued)
And Later
System Architecture Evolution (SAE) will deal with mobility between inter-access technologies
• In the longer term
• Early stage of consideration
