PURPOSE:To attain the announcement service indicating a power supply off-state to a caller by providing a memory storing on/off state of a power supply to receive a general service request designated from a mobile terminal equipment to an exchange and checking the memory when a call comes to the mobile terminal equipment. CONSTITUTION:A mobile terminal equipment 10 informs a switching time to an exchange by operation information of a dialer 11. For example, when the exchange receives a special dial number as a power supply on/off time setting request, a time signal extraction section 21 extracts an off-time and an on-time received next and the time is stored in an area corresponding to a caller subscriber of a switching time memory 22. In the case of the arrival of a call with a subscriber number, a state discrimination section 26 of the exchange 20 checks a subscriber state memory 25 and reads the power supply off-state, an announcement section 27 is driven. The announcement section 27 implements the announcement service such as 'The called party is absent and the power supply is interrupted just now', the switching time memory 22 is checked depending on the same subscriber number, the power supply ON time is extracted resulting in attaining the announcement service such as 'Please wait your dialing till the afternoon because the power supply is available at 13:00'. |
