ABSTRACT:
A mobile communication apparatus capable of controlling housing temperature is provided. The mobile communication apparatus includes a first and a second modules, an operating mode manager for managing a plurality of modes based on a combination of whether the first and the second modules each are supplied with power, and a memory for storing a plurality of data relating a period of operating time to a value of housing temperature for each of the modes. The communication apparatus includes a temperature estimator configured to measure the operating time, and if the mode is changed, to estimate a first and a second values of housing temperature corresponding to the operating time of the mode before the change and of the mode after the change respectively, and to have the operating mode manager stop the operation if an estimation based on the first and the second values reaches a predetermined threshold.
