Abstract:
1. A mobile radio terminal, comprising: a communicating unit configured to perform radio communication with a base station belonging to a mobile communication network; a measuring unit configured to measure an electric field strength of a radio signal received by the communicating unit from a base station belonging to the mobile communication network; a first search unit configured to search for the base station by using a frequency at which the electric field strength of the radio signal measured by the measuring unit has a reference value or more out of a frequency group usable for communication with the base station belonging to the mobile communication network by the communicating unit; a second search unit configured to search for the base station by using the frequency group usable for communication with the base station belonging to the mobile communication network by the communicating unit; and a search control unit configured to perform control so as to search for the base station by the first search unit until a number of searches for the base station by the first search unit corresponds to an upper limit value of a number of searches previously set or stored, and to search for the base station by the second search unit if the base station search by the first search unit does not succeed by a time when the number of searches for the base station by the first search unit corresponds to the upper limit value previously set or stored.
