Abstract:
1. A mobile communication system which transmits a Down Link RRC message to user equipment from a radio network controller and receives a response message, comprising: an RLC portion of the radio network controller which divides a Down Link RRC message into RLC AMD_PDU and transmits them, and gives an RLC error notice to an RRC portion from the RLC portion when a number of RLC AMD_PDU resending is exceeded because RLC ACK cannot be received from the user equipment; and an RRC portion of the radio network controller which activates a timer to count up to a fixed period upon receipt of the RLC error notice, regards the RLC error as competition with inter-cell movement of the user equipment to reset the RLC portion of the radio network controller and stops the timer, when receiving CELL UPDATE within the fixed period, and makes RLC RESET INDICATOR be TRUE in RRC:CELL UPDATE CONFIRM from the radio network controller so as to reset the RLC portion of the user equipment.
