Abstract

To provide a portable telephone system in which use of the set is automatically limited in a site where the use of the set is limited and in which causes of non-response and other various information can be transmitted to an originating party who called the use-limited portable telephone set. The system includes a portable telephone output limiting management device issuing a radio wave signal of the output limiting command information from an antenna. On reception of the output limiting command information from the antenna, the portable telephone set enters into the output limiting mode to halt direct exchange with the base station and sends out the information on the fact that the set has entered into the output limiting mode and the information including the portable telephone set management number, telephone number reply message and a notification information flag to the portable telephone output limiting management device, which then takes the place of the portable telephone set to reply to the call-out from the base station until the time the portable telephone set receiving the output limiting command exits the site.
