Select from 34. Therefore, the management necessity information corresponding to the current state of the delivery person can be acquired. When the management unit necessity information “1” indicating that the position information needs to be managed is selected by the selection unit 32, the device-side transmission unit 36 transmits a transmission start instruction to the mobile phone 2. On the other hand, when the selection unit 32 selects the management necessity information “2” indicating that it is not necessary to manage the position information, the device-side transmission unit 36 transmits a transmission stop instruction to the mobile phone 2. To do. Therefore, the positioning unit 26 of the mobile phone 2 needs to measure the position information only when the position information management device 3 needs to manage the position information. In addition, the transmission start instruction instructs the positioning unit 26 to position the position information at regular time intervals. Therefore, since the frequency of positioning and transmission of position information can be reduced, the power consumption of the communication terminal can be further reduced.
