PURPOSE:To shorten a time for executing reception operations, to reduce energy consumption, to update and register in a short time when moving to a different small radio zone and to correctly form a speech path with a communicating party when a call is terminated concerning the mobile communication terminal equipment of a digital mobile communication system to communicate the general terminal equipment of a public network while intermittently receiving radio waves from radio base station, then registering them as the communicatable small radio zones when the radio waves are higher than a certain level receive them. CONSTITUTION:A judgement circuit is provided to measure the electric field intensity of the radio waves from the radio base station and to judge it according to the change of the measured value with the passage of time whether the change of the said electric field intensity is increased or decreased, and a control circuit is provided to change the time interval of the intermittent reception according to the judged result of the said judgement circuit. Then, the interval of the intermittent reception is controlled to be short when the measured value of the electric field intensity is lower than a reference value and is decreased and to be long when the measured value of the electric field intensity is higher than the reference value and is increased. |
