What’s you’re mobile doing?
So what do you think you’re mobile is doing right now! Well if you are not making a call then it could be doing one of the following:-
1) Registering it’s existence
2) Scanning for suitable cells
3) Listening to cell broadcasts
4) Updating its location
5) Selecting or re-selecting cells
This is the case in most GSM system but could vary between networks. In general you’re mobile is doing a lot more than sitting in your back pocket.
However if you are making a call then it is most likely maintaining this call but in order to do this it is frequently measuring neighbouring cells and reporting back to the network The mobile is frequently receiving instructions to control its power and align it’s timing with the network. Measurement reports sent by the mobile is used to make handover decisions, this enables calls to be maintained while you are moving between cells.
In fact you’re mobile can make up to 100 measurements within a 480ms measurement cycle and still have time to search for synchronisation channels.
