  1. Wireless Convergence Architecture: A Case Study Using GSM and Wireless LAN NIKOS A. NIKOLAOU NICHOLAS A. ZERVOS 報告者: 通訊所 陳瑞文 學號: 692430034 授課教授: 潘仁義 老師 3G Presentation

  2. Outline • To know GSM (GPRS) architecture. • Wireless Convergence Architecture (WCA) 3G Presentation

  3. GSM 3G Presentation

  4. GPRS (1/2) • 增加新節點: • GGSN(Gateway GPRS Support Node) • 提供路由資訊與計費 • 提供預外部PDN網路的介接 • 藉由IP-Base之GPRS backbone與SGSN連接 • SGSN(Serving GPRS Support Node) • 類似MSC功能: 提供認證、加密、計費… • 提供access control與security管理 • 提供location資訊 • 與BSS連接 3G Presentation

  5. GPRS (2/2) • GSM網路修改與升級 • BSS修改與升級 • PCU (Packet Control Unit) • CCU (Channel Control Unit) • HLR升級 • SMS-GMSC、SMS-IWMSC升級 • MSC/VLR升級 3G Presentation

  6. Next Generation Mobile Environment Vision for the next generation mobile environment 3G Presentation

  7. WCA Protocol Stack 3G Presentation

  8. ASL and CM interoperation • ASL: Abstract Socket Layer • CM: Communication Manager • The Abstract Socket Layer (ASL) and Communication Manager (CM) pair of modules provide application resiliency to wireless link disruptions. 3G Presentation

  9. Reference Network Environment 3G Presentation

  10. Tested infrastructure. 3G Presentation

  11. Test Result 3G Presentation

  12. Conclusion • WCA offers a realized and test paradigm of the feasibility of uninterrupted connectivity. Moreover, it combines off-the-shelf hardware components that can be easily integrated. 3G Presentation
