Abstract

<P>PROBLEM TO BE SOLVED: To provide portable communication terminals in which a master terminal notifies a user of a first mode when a signal from a slave terminal is not received, and the master terminal notifies the user of a second mode when a predetermined operation is performed at the slave terminal. <P>SOLUTION: In a short-range communication system where a master terminal (portable communication terminal 100) and a slave terminal (portable communication terminal 100a) communicate via a short-range communication section 109, when a signal from the master terminal is not received, according to the disclosed portable communication terminal, the slave terminal is shifted to an operation monitoring mode by acquiring position information and transmitting it to an information server 200 and when a preset operation is detected in the slave terminal, notification information is transmitted to the master terminal. When there is no reception from the slave terminal because of signal level reduction, the master terminal generates notification output in a first mode and in response to user operation, position information of the slave terminal is acquired from the information server. When notification information indicating execution of the predetermined operation is received from the slave terminal shifted to the monitoring mode thereafter, a user is notified of the reception by notification output in a second mode. <P>COPYRIGHT: (C)2010,JPO&INPIT

Pairing between the child device and the parent device can be performed as appropriate, and a pair can be formed with any child device each time the device is used. After configuring the pair, it is monitored whether or not the slave unit is not more than a predetermined distance from the master unit. Monitoring is performed by checking the ID numbers of the slave units. If the ID numbers do not match or the ID numbers cannot be acquired (received), a warning is given by a buzzer or the like, so that the slave unit can be shared by multiple people. There has been disclosed a misplacement / theft prevention system that provides a portable terminal system which is possible but has few false recognitions, false alarms and false alarms.

  Further, in Patent Document 4, a step of providing wireless communication means that operates within a predetermined distance from a parent object in the parent object and at least one child object, and a step of periodically signaling the at least one child object Determining whether the at least one child object is within the predetermined distance based on whether a response to the signaling is received from the at least one child object.
