Abstract:
1. A mobile wireless terminal comprising: a wireless receiving part configured to receive a wireless signal from a base station which belongs to a mobile communication system using a time-frequency conversion for baseband processing; a received signal processing part that includes a time-frequency converting circuit and is configured to process the wireless signal from the base station which belongs to the mobile communication system; a setting part configured to successively set, in the wireless receiving part, central frequencies within regions, wherein a frequency band that the mobile communication system uses is divided into the regions having the same bandwidth or different bandwidths; and a received signal strength measuring part configured to measure signal strength of a received signal in the received signal processing part over the regions of the frequency band that the mobile communication system uses based on time-frequency conversion results from the time-frequency converting circuit and during a time other than at the time of an intermittent reception in which a predetermined process is performed if the mobile wireless terminal performs an intermittent receiving operation at a predetermined intermittent receiving cycle, the time-frequency conversion results being obtained for the respective regions using the respective central frequencies set by the setting part, the respective central frequencies set by the setting part enabling searching for a base station which belongs to a second mobile communication system not using the time-frequency conversion for the baseband processing and using the measured signal strength.
