Abstract
A method of controlling a mobile information terminal that includes a device for identifying a position of the mobile information terminal based on a received signal includes activating, by a processor, the device based on a reception status of the received signal before deactivating the device, and an index related to movement of the mobile information terminal after deactivating the device.
Claims15
A method executed by a processor included in a mobile information terminal, the mobile information terminal including a module device that identifies a position of the mobile information terminal based on a received signal received from each of a plurality of satellites, the method comprising:
- deactivating the module device when a number of satellites of which signal strength is equal to or greater than a predetermined strength, the number indicating a reception status of the received signal, is less than a threshold;
- selecting an index from a plurality of indices, each index related to a movement of the mobile information terminal after deactivating the module device;
- extracting from a memory a determination parameter, from a plurality of determination parameters defined for each of the indices, the extracted determination parameter corresponding to the number indicating the reception status of the received signal;
- and
- activating the module device when a value of the selected index is determined to satisfy the extracted determination parameter.
A mobile information terminal comprising:
- a module device configured to identify a position of the mobile information terminal based on a received signal received from each of a plurality of satellites;
- and
- a processor configured to:
- deactivate the module device when a number of satellites of which signal strength is equal to or greater than a predetermined strength, the number indicating a reception status of the received signal, is less than a threshold,
- select an index from a plurality of indices, each index related to a movement of the mobile information terminal after deactivating the module device,
- extract from a memory a determination parameter, from a plurality of determination parameters defined for each of the indices, the extracted determination parameter corresponding to the number indicating the reception status of the received signal, and
- activate the module device when a value of the selected index is determined to satisfy the extracted determination parameter.
A non-transitory computer readable storage medium that stores a control program for causing a mobile information terminal that includes a module device that identifies a position of the mobile information terminal based on a received signal received from each of a plurality of satellites to execute a process, the process comprising:
- deactivating the module device when a number of satellites of which signal strength is equal to or greater than a predetermined strength, the number indicating a reception status of the received signal, is less than a threshold;
- selecting an index from a plurality of indices, each index related to a movement of the mobile information terminal after deactivating the module device;
- extracting from a memory a determination parameter, from a plurality of determination parameters defined for each of the indices, the extracted determination parameter corresponding to the number indicating the reception status of the received signal;
- and
- activating the module device when a value of the selected index is determined to satisfy the extracted determination parameter.
