There are four RRC states present in UMTS .
1.CELL_DCH STATE
2.CELL_FACH STATE
3.CELL_PCH STSTE
4.URA_PCH STATE
WHEN MOBILE IS MOVING FROM IDLE MODE TO DEDICATED MODE AND
DATA TRANMISSION IS OF LARGE AMOUNT OF DATA THEN CELL_DCH
STATE COMES IN TO PICTURE .
IF DATA TRANSMISSION IS OF SMALL AMOUT OF DATA THEN
CELL_FACH STATE WILL COME IN TO PICTURE
WHEN MOBILE IS MOVING FROM ONE CELL TO ANOTHER CELL IT
SHOULD PERFORM HANDOVER THEN MOBILE RRC STATE WILL BE IN
CELL_PCH STATE.
URA MEANS UTRAN REGISTRATION AREA
THE AREA COVERED BY ONE RNC IS KNOWN AS URA
SO WHEN MOBILE IS MOVING FROM URA AREA TO ANOTHER URA AREA
THEN LOCATION UPDATION SHOULD PERFORM THEN MOBLIE RRC STATE
COMES TO URA_PCH STATE .
THESE ARE THE FOUR RRC STATES PRESENT IN UMTS NETWORK
