Abstract
A method for performing Cell-Updates or URA-Updates in a mobile communication system is disclosed, whereby a User Equipment (UE) sends a Cell-Update message or URA-Update message to an SRNC. The-transported Cell-Update message or URA-Update message includes a sequence counter which is incremented each time the UE sends such a message to the SRNC. The SRNC stores the value of the sequence counter for each Cell-Update message or URA-Update message received and acknowledged. If the SRNC receives a Cell-Update message or URA-Update message with a corresponding sequence counter value'that is lower than the sequence counter value stored for the previously received Cell-Update message or URA-Update message, then the SRNC ignores the received Cell-Update message or URA-Update message. Also, the SRNC does not store the sequence counter value for the ignored, received Cell-Update message or URA-Update message.
