TRACKING AND POSITIONING OF MOBILE SYSTEMS IN TELECOMMUNICATION NETWORKS
[attachment=27735]
WHY TRACKING
Emergency service for subscriber safety.
Location sensitive billing.
Cellular Fraud detection.
Intelligent transport system services.
Efficient and effective network performance
and management.
DISTANCE BASED POSITIONING-TOA METHOD
The TOA method calculates the distance of a mobile telephone and a BS based on the TOA of a signal transmitted from the mobile telephone at the BS.
The distance is calculated by the following equation
ADVANTAGES
Our proposal is advantageous in that the location of a mobile telephone can be accurately tracked even in the multi-path fading and the NLOS environment, by using more accurate tracking curves connecting the intersection points among circles.
We have described about accurate positioning of mobile telephones, which can be used for several applications.
The important considerations to be undertaken while selecting a location based technology are location accuracy, implementation cost, reliability, increasing functionality.
