Abstract
Disclosed are a hybrid mobile communication terminal and a method of controlling operation modes of the terminal. The hybrid mobile communication terminal includes a first communication unit communicating with a first communication system capable of offering voice services and low-speed data transmission, a second communication unit communicating with a second communication system capable of offering high-speed data transmission, and a mode controller for controlling a switching operation between the first and second communication units, wherein the mode controller includes a preference access setup unit which sets so that a data call connection to the first communication system is attempted during a predetermined time interval when the mode controller fails to establish a call connection with the second communication system in a hybrid operation mode in which the mode controller alternately attempts to access the first and second communication systems using the first and second communication units. The method includes the step of attempting to establish a data call connection to a 1.times. mode during a predetermined time interval upon failure in call connection to an EV-DO (Evolution-Data Optimized) system during a hybrid operation mode.
