This is an aproaching process:
#Scan 124 RF channels and measure
signal strength for 3-5 seconds
#Tune to the RF channel with the highest
received average signal strength
#Determine if it is a BCCH carrier by searching for frequency correction bursts.
#Is it a BCCH carrier? The MS shall attempt to synchronize to This carrier and read BCCH info
#Is it the wanted PLMN?
#Is the cell barred for access?
#Is C1 > 0?
#Camp on the cell
IF THE ONE OF THIS STAGES NOT ACCOMPLISHED THE MOBILE WILL TUNE AGAIN AT ANOTHER STRONGE FREQUENCY.

2 After power on, a period of at least n minutes and at most T
minutes is elapsed before the first attempt is made.
3 The MS makes an attempt if it is on the visiting PLMN at
time T after the last attempt.
4 Periodic attempts are only to be performed by the MS while
in idle mode.
5 If the home PLMN is not found, the MS remains on the
