Transcript of "Gymn0702"

  1. 1. Implementing Operator-Independent Location Based Services
  2. 2. Presentation Outline <ul><li>What are LBS'? </li></ul><ul><li>How does LBS work? </li></ul><ul><ul><li>GPS </li></ul></ul><ul><ul><li>TOA </li></ul></ul><ul><ul><li>E-OTD </li></ul></ul><ul><ul><li>COO </li></ul></ul><ul><li>An operator-independent approach </li></ul><ul><li>How is it implemented? </li></ul><ul><li>Real World Examples </li></ul><ul><li>Other questions? </li></ul>
  3. 3. What are LBS'? <ul><li>Location Based Services are services that are contextually location-specific? </li></ul><ul><ul><li>Questions are of the variety – what, when, where, how... </li></ul></ul><ul><ul><li>LBS try to answer the question – where! </li></ul></ul><ul><li>Examples of Location Based Services </li></ul><ul><ul><li>Emergency Services </li></ul></ul><ul><ul><li>Traffic Information </li></ul></ul><ul><ul><li>Navigational Assistance </li></ul></ul><ul><ul><li>Stolen Vehicle Recovery </li></ul></ul><ul><ul><li>Fleet Tracking </li></ul></ul><ul><ul><li>Enhanced Directory/Information Services </li></ul></ul>
  4. 4. How does LBS work? <ul><li>LBS uses wireless location technologies </li></ul><ul><ul><li>GPS </li></ul></ul><ul><ul><li>TOA </li></ul></ul><ul><ul><li>E-OTD </li></ul></ul><ul><ul><li>COO </li></ul></ul>
  5. 5. GPS <ul><li>GPS (Global Positioning System) is a system that uses a constellation of satellites beaming timing signals to the earth to determine the location of a device. </li></ul>
  6. 6. Uplink Time of Arrival <ul><li>Uplink Time of Arrival uses a network of base transmission stations (BTS) to determine the location of a mobile terminal by estimating the time (and hence distance) it takes for a signal to be received by each of the BTS in the setup. </li></ul>
  7. 7. Enhanced Observed Time Difference <ul><li>E-OTD uses timing signals sent from several BTS to the mobile terminal. The mobile terminal in turn estimates location from this data and either reports it location back or consumes it. </li></ul>
  8. 8. Cell of Origin <ul><li>The COO method uses reported information on the cell site a mobile equipment is connected to in determining the location of the mobile equipment. This is done by looking up the cell id, local area code and others against a database. </li></ul>
  9. 9. Why consider operator-independence? <ul><li>Operators can be slow in deploying bleeding-edge technology </li></ul><ul><li>Operator bureaucracy </li></ul><ul><li>Development costs </li></ul>
  10. 10. Implementation <ul><li>First things first – we ought to build a database of cell sites </li></ul><ul><ul><li>Using a technique known as cell stumbling </li></ul></ul><ul><li>Secondly, create an interface or API for easy integration with other applications </li></ul><ul><li>Thirdly, create a application to consume the service </li></ul>
  11. 11. Real World Applications <ul><li>Dodgeball.com </li></ul><ul><li>Culture around the corner </li></ul><ul><li>Meet Moi </li></ul>
  12. 15. Questions <ul><li>Questions? </li></ul><ul><li>Questions?? </li></ul><ul><li>Questions??? </li></ul>
