Presentation Transcript

  1. A study of Unlicensed Mobile Access(UMA) Technology • Presenter: Khanh Nguyen • Instructor: Chin-Chih Chang

  2. A study of Unlicensed Mobile Access(UMA) Technology • Introduction • Characteristics of UMA • Architecture • UMA Applications • Conclusion

  3. UMA Participating Companies • Alcatel • British Telecom • Cingular • Ericsson • Kineto Wireless • Motorola • Nokia • Nortel Networks • O2 • Research in Motion • Rogers Wireless • Siemens • Sony Ericsson T-Mobile US

  4. Why UMA? Unlicensed Mobile Access (UMA) technology enables access to GSM and GPRS mobile services over unlicensed spectrum, including Bluetooth™ and WiFi™.

  5. Architecture Overview

  6. Protocols • Standard 3GPP Protocols • Standard Unlicensed Radio Access Protocols • Standard IP-based Protocols • UMA Specific Protocols • UMA-RR • UMA Radio Link Control

  7. UMA Security Mechanisms

  8. How UMA Technology Works

  9. Specification History • Stage 1 Specification(User Perspective) 9/1/2004 • Stage 2 Specification(Architecture) • UMA Stage 2 R1.0 9/1/2004 • ………. • UMA Stage 2 R1.0.4—Clean 5/16/2005 • Stage 3 Specification(Protocols) • UMA Stage 3 R1.0 9/1/2004 • ……. • UMA Stage 3 R1.0.4—Clean 5/16/2005

  10. Development • Philips Electronics announced a complete Unlicensed Mobile Access (UMA) semiconductor reference design to make it easy for mobile handset manufacturers to bring UMA-enabled phones to their customers
