Abstract
A wireless communication terminal is disclosed which has mass data such as stream data delivered thereto efficiently over a wireless communication network so that the overall utilization efficiency of the network is improved as well. While a wireless communication terminal () is receiving stream data for its use, a main controller () checks a radio wave reception level LB coming from a receiver unit () in the terminal. If the reception level is found to drop below a predetermined level, the main controller () causes a frequency synthesizer () to control reception frequencies fed to the receiver unit () so as to receive radio waves from a plurality of base stations in the vicinity. A search is thus made for a base station which offers a radio wave reception level higher than the predetermined level and which is delivering the stream data in question, and that base station is selected preferentially.
