  1. GPRS Technology Technical Seminar Under the guidance Of Mr. N.SRINIVASU

  2. What is GPRS • GPRS is a new set of GSM-bearer services that provide packet mode transmission within the GSM network & interconnects with external packet data networks.

  3. Wide-Area Cellular Network Evolution to 3G

  4. GPRS Network

  5. How Does GPRS Work? When a user turns on a GPRS device, typically it will automatically scan for a local GPRS channel. If an appropriate channel is detected, the device will attempt to attach to the network. The SGSN receives the attach request, fetches subscriber profile information from the subscriber’s HLR node, and authenticates the user. Ciphering may be established at this point.

  6. Sending and Receiving Packets When the mobile user sends data, the SGSN routes the packets to the appropriate GGSN. The GGSN then routes the data according to the current "context" established for the session. Conversely, packets destined for the user are routed to the GGSN associated with the user's IP address. The GGSN checks the received packets against the current context, identifies the SGSN that is serving the user, and routes the traffic accordingly. The SGSN then forwards the packets to the BSS where the subscriber is located.

  7. Applications for GPRS • CHAT • TEXTUAL AND VISUAL INFORMATION • STILL IMAGES • MOVING IMAGES • WEB BROWSING

  8. Applications for GPRS Contd.. • DOCUMENT SHARING/ COLLABORATIVE WORKING • AUDIO • JOB DISPATCH • CORPORATE EMAIL • INTERNET EMAIL • VEHICLE POSITIONING • REMOTE LAN ACCESS

  9. Advantages of GPRS • Faster Data Transfer Rates • Always-On Connection • Robust Connectivity • Broad Application Support • Security Support

  10. Implementing GPRS in Business Network • GPRS Notebook Solutions • Notebook Connection Using Cell Phone • GPRS-Enabled Notebook
