  1. GSC11_JOINT_42 High Interest Subject:Internet Protocol Over Wireless Prime PSO: ATIS Presenter: Asok Chatterjee GSC: Standardization Advancing Global Communications

  2. IP Over Wireless 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

  3. IP Over Wireless 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?

  4. IP Over Wireless The Vision – “All IP Network” AIPN PSTN Common IP-based network Support of a variety of Different access systems Advanced mobility management Session management Enhanced Services Enhanced network performance Network extensibility composition External IP Networks e.g. Internet Security and Privacy functionality QoS Terminal and User identification Other Access Systems (broadband fixed and wireless) Seamless User Experience WLAN Future 3GPP Access Systems Existing 3GPP Access systems End to End QoS Guaranteed Connection Session mobility Terminal- mobility

  5. IP Over Wireless From Core Networks to Access Networks Access Networks • Wireline • Wireless IP Network Core • The IMS (IP Multimedia Subsystem) is now accepted as a viable basis for the core of an all-IP network.

  6. IP Over Wireless 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 Reference: “All IP in 3G CDMA Networks”, Jonathan P. Castro, John Wiley & Sons, 2004

  7. IP Over Wireless 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)

  8. IP Over Wireless 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?

  9. IP Over Wireless 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

  10. IP Over Wireless 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

  11. IP Over Wireless 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
