Abstract: An interrupt controlling method and apparatus is disclosed. The method and apparatus generates allows a connecting gate to output different signals according to whether charging electric power or communication electric power is supplied to the connector unit of the portable terminal and then outputs them to the power management IC. The power management IC performs a controlling operation in such a way that it can generate only a charging interrupt command if a travel adaptor is connected to the connector unit and generate a communication interrupt when the communication device is coupled to the connector unit.

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.
