<P>PROBLEM TO BE SOLVED: To secure probability that an emergency-transmission base station device is selected in a mobile radio terminal used in a radio system wherein a normal-transmission base station device for constant output of a transmission signal using at least one channel and the emergency-transmission base station device for output of a transmission signal using at least one channel different from the channel used by the normal-transmission base station device when a transmission request is issued are mixed. <P>SOLUTION: A channel selection means sets a reception standby time in a channel used in the emergency-transmission base station device longer than that in a channel used in the normal-transmission base station device, and sequentially scans channels used in the respective base station devices to select a channel optimized a reception state as a reception channel. <P>COPYRIGHT: (C)2010,JPO&INPIT |
