Abstract
Information processing device (100) communicates with mobile terminals (200-1) to (200-2). Mobile terminals (200-1) to (200-2) perform near field communication with each other. Information processing device (100) decides a condition based on a distance from a first location associated with user information about users who use mobile terminals (200-1) to (200-2) to their current location and notifies mobile terminals (200-1) to (200-2) whether or not other user identification information that satisfies the decided condition has been stored.
Claims9
An information processing device, comprising:
- a communication section that acquires current location information and user identification information from a mobile terminal, the current location information representing a current location of the mobile terminal;
- a storage section that correlatively stores user information associated with the user identification information and a first location associated with the user information;
- a condition decision section that decides a condition based on a distance from the current location represented by the current location information acquired by said communication section to said first location;
- and
- a control section that searches said storage section for other user identification information that satisfies the condition decided by said condition decision section and transmits condition information, that represents the condition and presence information that denotes whether or not the other user identification information that satisfies said condition has been stored in said storage section as said searched result, to a mobile terminal identified by said acquired user identification information through said communication section.
A mobile terminal that performs radio communication, comprising:
- a near field communication section that has a near field communication function;
- a location information acquisition section that acquires location information that represents a current location of the mobile terminal;
- and
- a communication section that transmits the location information acquired by said location information acquisition section and user identification information of a user who uses the mobile terminal to another device.
A communication method, comprising the processes of:
- acquiring current location information and user identification information from a mobile terminal, the current location information representing a current location of the mobile terminal;
- deciding a condition based on a distance from the current location represented by said acquired current location information to a first location associated with said user identification information;
- searching a storage section for other user identification information that satisfies said decided condition, said storage section correlatively storing the user information associated with the user identification information and the first location associated with the user information;
- and
- transmitting condition information, that represents said condition and presence information that denotes whether or not the other user identification information that satisfies said condition has been stored in said storage section as said searched result, to a mobile terminal identified by said acquired user identification information.
