A method of determining the present electric field state of a mobile station also in view of an uplink electric field state is disclosed. A TPC bit counter 30 is supplied with a received signal processed by a baseband processor 20, and counts TPC bits contained in a predetermined time span, preferably one radio frame. A received electric field state determining unit 50 measures the electric field strength of the received signal from the base station which has been received by an RF receiver 10. An electric field strength measuring unit 40 determines a TPC bit evaluation value from the TPC bit sum calculated by TPC bit counter 30, determines a received electric field strength evaluation value from the received electric field strength measured by the received electric field state determining unit 50, multiplies the TPC bit evaluation value by the received electric field strength evaluation value to calculate an electric field state evaluation value, and controls an alarm unit 60, a display unit 70, and an LED unit 80 based on the calculated electric field state evaluation value for thereby indicating the electric field state. |
