| 摘要 |
The present invention is a communication terminal apparatus capable of making communication via a base station connectable with a communication network. The apparatus includes first control means (10a) for receiving a signal transmitted from a serving base station, first level detection means (5) for detecting a level of the signal transmitted from the serving base station, second control means (10a) for stopping the operation of the receiving means (3) if the level detected by the first level detection means (5) is equal to or higher than a threshold value, third control means (10a) for receiving a signal transmitted from a base station other than the serving base station if the level detected by the first level detection means (5) is lower than the threshold value, second level detection means (5) for detecting a level of the signal received under control of the third control means (10a), and threshold value varying means (10a) for varying the threshold value in accordance with which of the level detected by the first level detection means (5) and the level detected by the second level detection means (5) is higher. <IMAGE> |
