  1. COE 543 Wireless NetworksTerm Project GPRS Capacity Evaluation Presented By Yaser Al-Jarbou May 2004

  2. Agenda • Introduction • GSM/GPRS Technology • Simulation Model • Results Discussion • Reference Paper • Conclusion

  3. GPRS • GPRS: General Packet Radio Service • GPRS is a service that provides packet mode transmission within the GSM network & interconnects with external packet data networks.

  4. What is GPRS? • 2.5 G • GPRS is an overlay network over the GSM • Very Little change to GSM infrastructure • Provides Data Packet delivery service • Standardized by ETSI • Direct support for Data Network

  5. Applications • Web browsing • Email • Banking Transactions • Stock Market Updates • News • Weather & Traffic reports

  6. Features • High Data Rates of about 100 kbps – an order of magnitude higher than GSM • The setup time is negligible – less than a second • Resource utilization as per requirements – air interface is assigned temporarily on per-packet basis • Hosts can remain “always on”

  7. GSM Architecture

  8. GPRS Additions

  9. GPRS Additions (Cont.) • SGSN – Serving GPRS support Node. • Performs packet routing & transfer • Mobility management – attach/detach & location management • Logical Link Management • AAA • Stores user Profiles of all MS within its purview

  10. GPRS Additions (Cont.) • GGSN – Gateway GPRS support Node • Interface between GPRS backbone & External packet data networks • Converts GPRS packets into appropriate Packet Data Protocol & vice-versa • It may also perform AAA • Many-2-Many relationship may exist between SGSN & GGSN

  11. Mobile Classes Three types of Mobile Classes • CLASS A: « Rolls Royce » CS Core Network (GSM) Simultaneous CS/PS Paging Simultaneous CS/PS data transfer PS Core Network (GPRS) • CLASS B: « Standard » CS Core Network (GSM) Simultaneous CS/PS Paging CS call or PS data transfer PS Core Network (GPRS) • CLASS C: « Cheap » CS Core Network (GSM) CS mode (GSM only) or PS mode (GPRS only) PS Core Network (GPRS)

  12. Project Title • GPRS Capacity Evaluation • Goal: Simulate the capacity needed for GPRS in coexistence with the circuit switched services. • Reference Paper: • Peter Stuckmann, Frank Muller, “GPRS Radio Network Capacity and Quality of Service using Fixed and On-Demand Channel Allocation Techniques”, IEEE 2000. • Tool: Microsoft .NET C#
