Abstract: Provided is a method for preventing excessive handovers in a mobile communication system. In the method, a periodic measurement report message is transmitted from a mobile terminal to a network. The network determines, on the basis of the measurement report message from the mobile terminal, whether a handover of the mobile terminal needs to be performed. Thereafter, the network transmits a Handover_Command message to the mobile terminal if the handover of the mobile terminal needs to be performed. Upon receipt of the Handover_Command message, the mobile terminal performs a handover to a target handover cell according to the Handover_Command message, transmits a Handover_Complete message to the network, and transmits a first measurement report message including neighboring cell information set to Null from the mobile terminal to the network after the transmission of the Handover_Complete message.

Abstract: Disclosed is a method for handling inter-RAT cell measurement in a dual-mode UE in a connected mode, which supports both GSM/GPRS (Global System for Mobile communication/General Packet Radio Service) RAT (Radio Access Technology) and UMTS (Universal Mobile Telecommunications System) RAT. A UTRAN (UMTS Terrestrial Radio Access Network) of the UMTS RAT transmits a measurement control message to a URRC (UMTS Radio Resource Control) of a UMTS network layer in the UE. Upon receiving the measurement control message, the URRC sends a measurement request for GSM cells to an RR/GRR (Radio Resource/GPRS Radio Resource) of a GSM/GPRS network layer. The RR/GRR activates a GSM physical layer and sends a measurement request for the GSM cells to the GSM physical layer. The GSM physical layer performs measurement on the GSM cells and reports a measurement value to the RR/GRR. The RR/GRR reports the measurement value for GSM cells, received from the GSM physical layer, to the URRC. The URRC reports the received measurement value for GSM cells to the UTRAN.
