  1. 1. PROJECT<br />REPORT<br />ON<br />GSM<br />
  2. 2. OVERVIEW OF MTNL<br />MTNL was set up on 1st April, 1986 by government of India to upgrade the quality of telecom services.<br />WEBSITE-http:// www.mtnl.net.in<br />
  3. 3. WHAT IS GSM ?<br />Global system for mobile communication , a mobile phone system based on multiple radio cells.<br />Two main standards :-<br />GSM 900 – Designed for extensive radio coverage in rural areas<br />DCS 1800 – Designed for radio coverage in areas with very high subscriber density<br />
  4. 4. WHAT IS GPRS?<br />It is new non voice value added services that allows information to be sent and received across a mobile telephone network.<br />
  5. 5. WHAT IS AN EDGE?<br />Edge- Enhanced data rates for global evolution.<br />It is 3G technology that delivers broadband. It allows consumers to connect to the Internet and send & receive data.<br />
  6. 6. GSM<br />( Global system for mobile communication )<br />SMART AND SECURE <br />GSM is so secure & flexible with its functionalities & so easy to manipulate.<br />GSM subscribers are identified by their SIM card.<br />
  7. 7. SIM CARD<br />-SIM is removable.<br /><ul><li>Subscriber inserts it in mobile station unit.
  8. 8. Provide PIN,which is compared with PIN stored within the SIM.</li></li></ul><li>GSM TELECOMMUNICATION SERVICES<br />Services offered to GSM subscriber are:<br /><ul><li>Bearer services( For data only )
  9. 9. Tele services ( For voice & data )</li></ul>- Supplementary services<br />
  10. 10. CHARACTERISTICS FOR GSM<br /><ul><li>Frequency band
  11. 11. Duplex Distance
  12. 12. Channel separation
  13. 13. Modulation
  14. 14. Transmission rate
  15. 15. Access Method</li></li></ul><li>GSM FREQUENCIES<br />FREQUENCY RANGE<br />GSM900 880-915 MHz paired with 925-960MHz<br />GSM1800 1710-1785MHz paired with 1805-1880MHz<br />GSM1900 1850-1910MHz paired with 1930-1990MHz<br />
  16. 16. GSM ARCHITECTURE<br />
  17. 17. GSM ARCHITECTURE<br />GSM system is basically designed as combination of 3 subsystems:<br /><ul><li>Switching subsystem ( SSS )
  18. 18. Radio subsystem ( RSS )
  19. 19. Operation and maintenance subsystem (OMS )</li></li></ul><li>COMPONENTS OF RSS<br />RSS consists of :<br /><ul><li>Mobile Equipment (ME)
  20. 20. Base Station (BS)
  21. 21. Radio Interface (Um)</li></ul>BS includes :<br /><ul><li>Base Transceiver Station (BTS)
  22. 22. Base Station Controller (BSC)
  23. 23. Transcoding & Rate Adaptation Unit (TRAU)</li></li></ul><li>COMPONENTS OF SSS<br />SSS Consists Of :<br /><ul><li>Mobile Services Switching Centre (MSC)
  24. 24. Home Location Register (HLR)
  25. 25. Visitor Location Register (VLR)
  26. 26. Authentication Centre (AC)
  27. 27. Equipment Identification Register (EIR)</li></li></ul><li>OMS ( OPERATION & MAINTENANCE CENTER )<br />An OMS consists of one or more operation & maintenance center.<br />-The OMC is connected to all equipment in the switching system & to the BSC. <br />-The implementation of OMC is called the operation and support system (OSS). <br />-The OSS is the functional entity from which n/w operator controls the system.<br />
  28. 28. GSM NETWORK AREAS<br />
  29. 29. NETWORK AREA<br />CELL: is the area covered by one base transceiver station.<br />Location Area: is the group of cells.<br />MSC/ VLR service area: represents the part of GSM network that is covered by one MSC.<br />
  30. 30. VALUE ADDED SERVICES<br />-Call Waiting<br />-Call Divert<br />-Voice Response Services<br />-Mail<br />
  31. 31. JOINT VENTURES OF MTNL<br />-United Telecom Limited (UTL) <br /><ul><li>Mahanagar Telephone Mauritius Limited (MTML)
  32. 32. MTNL-STPI IT Services Limited
  33. 33. Millenium Telecom Limited(MTL)</li></li></ul><li>THANKS<br />
