| 23rd August 2004 - 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.
