A mobile radio device capable of receiving a radio signal whose frequency band switches, includes a setting unit that when the frequency band of the radio signal is a first frequency band, sets a first threshold corresponding to the first frequency band, and that when the frequency band switches from the first frequency band to a second frequency band different from the first frequency band, sets for a given period, a third threshold that is between the first threshold and a second threshold corresponding to the second frequency band and subsequently sets the second threshold; and a determining unit that determines a travel speed of the mobile radio device, based on a comparison of a moving average obtained by temporally accumulating variations of estimates of propagation characteristics of the radio signal and averaging the accumulated variations by a moving average method using a threshold set by the setting unit.

Mobile radio device and determining method

A mobile terminal communicating with a plurality of cells, including a serving cell, has a control unit. The control unit performs at least one control of (a) a first control for causing a path search unit to detect a path for the serving cell more preferentially than paths for cells other than the serving cell, (b) a second control for causing a finger assignment unit to assign a path detected for the serving cell preferentially over paths detected for cells other than the serving cell to a plurality of fingers, and (c) a third control for causing a reference frequency adjustment unit to adjust reference frequency so that the reference frequency is approximated to reference frequency of a base station controlling the serving cell.

Mobile terminal and communication control method

A mobile terminal has a communication unit for performing wireless communication, a plurality of modem units for performing modulation and demodulation in different communication methods, respectively, and a control unit for obtaining time information indicating a suspension of a wireless communication from a main modem unit in the plurality of modem units, for suspending the main modem unit from performing wireless communication via the communication unit, and for enabling the main modem unit to perform wireless communication via the communication unit on the basis of the time information, wherein, while the main modem unit suspending wireless communication, the control unit enables a sub modem unit in the plurality of modem units to measure a reception level via the communication unit in accordance with the obtained time information.
