The present invention provides a relief method of competition between a Down Link RRC message and inter-cell movement of user equipment which can continue communication even when acknowledgment of the Down Link RRC message cannot be performed. An RLC layer of the radio network controller (RNC) divides a Down Link RRC message into RLC AMD_PDU and transmits them, and gives an RLC error notice to an RRC layer from the RLC layer when a number of RLC AMD_PDU resending is exceeded because RLC ACK cannot be received from user equipment (UE). An RRC layer of the radio network controller activates a timer. When receiving CELL UPDATE within a fixed period, the RRC layer regards the RLC error as competition with inter-cell movement of the user equipment to reset the RLC layer of the radio network controller. The RRC layer of the radio network controller makes RLC RESET INDICATOR be TRUE in RRC:CELL UPDATE CONFIRM from the radio network controller so as to reset the RLC layer of the user equipment.
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:
A relief method of competition between a Down Link RRC message and inter-cell movement of user equipment in a mobile communication system which transmits the Down Link RRC message to the user equipment from a radio network controller and receives a response message, the relief method of competition between a Down Link RRC message and inter-cell movement of user equipment in a mobile communication system comprises the steps of:
A radio network controller of a mobile communication system which transmits a Down Link RRC message to user equipment from a radio network controller and receives a response message, the radio network controller comprising:
