Positioning terminal and server

A positioning terminal comprising:

• a positioning unit configured to perform positioning processing for acquiring position information which indicate a current position of the positioning terminal;
• a position information reporting unit configured to transmit position information acquired by the positioning unit to a server;
• a determination result receiving unit configured to receive, from the server, a determination result as to whether or not the positioning terminal moves on a registered route formed by concatenating location points indicated by position information previously acquired by the positioning unit;
• and
• a positioning interval control unit is configured to change a positioning interval at which the positioning unit performs the positioning processing from a first time interval to a second time interval which is longer than the first time interval, when the determination result receiving unit receives a determination result that the positioning terminal moves on the registered route.

A server comprising:

• a receiving unit configured to receive, from a positioning terminal, position information indicating a current position of the positioning terminal;
• a storage unit configured to store a registered route formed by concatenating location points indicated by position information previously received by the receiving unit;
• a determining unit configured to determine whether or not the positioning terminal moves on the registered route;
• and
• a reporting unit configured to report a determination result by the determining unit to the positioning terminal, when the determining unit determines that the positioning terminal moves on the registered route.
