Tracking And Positioning Of Mobile Systems In Telecommunication Networks
[attachment=21899]
INTRODUCTION TO MOBILE TECHNOLOGY
Whole service area is divided into several coverage areas known as a “cell”.Each area has a separate base station(BS).
Every BS is provided with a frequency of range 450 to 900 MHz.
The MTSO controls the BSs so that the subscriber can continue his call without interruption.
Tracking the location within the boundary of a cell in a telecommunication network is known as “location based services”.
Mobile Technology includes mainly two functions namely call fixing and hands off process.
Call fixing is process of connecting a call.
Hands off is changing the BS frequency of the user.
ARCHITECTURE OF A GEOLOCATION SYSTEM
A geolocation service provider provides
location information and location aware
sevices to subscribers.
The service provider will contact the
location control center about the coordinates
of the mobile system (MS).
The location control center will gather
information required to compute the MS’s
location.
The service provider will then use this
information to visually display the MS’s
location to the subscriber.
The subscriber can be the MS itself.
GLOBLE POSITIONING SYSTEM (GPS)
To locate the mobile telephone by itself, the mobile telephone is provided with a GPS receiver to calculate its location.
There should be an unobstructed line of sight to four or more GPS satellites.
GPS satellites broadcast signals from space, which each GPS receiver uses to calculate its three-dimensional location (latitude, longitude, and altitude) plus the current time
GPS receivers are used in mobile phones, vehicles, marine navigation devices and military applications.
