There is this 15 digit serial number tht is unique to each wireless instrument,,,called IMEI number...
can be easily got by pressing * #06# on your GSM phone.
Now Mobile service provider and responsible authorities track for this IMIE #
When your mobile phone is switched on, your cellular network provider knows exactly where you are in the world to within a hundred metres or so.(OR Network cell with help of those IMIE)
Similar technology is used to track down lost aircraft and yachts through their radio beacons. It's not identical, because most radio beacons use satellites and cell phones use land-based aerial arrays, but the principle is the same.
At any one time, your phone is usually able to communicate with more than one of the aerial arrays provided by your phone network. They're ten or twenty kilometers apart (less in cities) and it's usually within range of at least three of them. So by comparing the signal strengths and time lags for the signals at each station, your network can triangulate your position and work out where you are.
This is true whenever your phone is switched on, whether you're using it or not, because every so often it sends out a check signal to make sure everything is working as it should.
Not surprisingly, the phone network companies are shy about admitting they have this ability. But within the industry, it's seen as just one more piece of data. There is even talk of selling the data to Internet content providers so they can send information to your Internet phone based on your location, for example reviews of nearby restaurants.
The triangulation capability of cell phone network companies varies according to the age of their equipment. A few can only do it manually with a big drain on skilled manpower. But these days most companies can generate the information automatically, which makes it cheap enough to sell.
hope this would help!! ♥ ♥

RE:
How does GSM mobile phone tracking actually work?

Mobile phone tracking technology relies on the use of triangulation - taking the signal strengths registered from your mobile phone at a minimum of three nearby GSM receiver masts. As the mobile phone companies know the position of each mast, and can tell the signal strength of your phone at each of these nearby masts, they can use this to calcuate your position to a certain degree of accuracy (within about 50 to 100 meters).

I have Virgin Mobile-which, actually a division of T-Mobile in England runs on the Sprint system in the US. It has the GSM module, even though I have the cheapest model. I do not think they or T-Mobile will carry a phone they cannot track on their system in the usual manner.

a GSM can tansmit upto 36 closest basestations and holds information on upto 100 these include basestations which don't have the correct colour codes (eith country or network) therefore with isinformation beeing held in HLR triangulation is simple

The 3 local base stations report the signal strength to the HLR in the network. They then use triangulation to work out where you are.
