Setting up of condition based on location for a mobile terminal

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.

1 . 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 the user identification information and a first location associated with the user identification information;   a decision section that decides extraction bounds based on a distance between the location represented by the current location information acquired by the communication section and the first location; and   a control section that transmits information that represents the extraction bounds decided by the decision section to a mobile terminal.   
     
     
         2 . The information processing device as set forth in  claim 1 ,
 wherein the control section transmits the user information associated with the other user identification information that has been retrieved in the extraction bounds that the decision section has decided to the mobile terminal through the communication section.   
     
     
         3 . The information processing device as set forth in  claim 1 ,
 wherein the communication section acquires supplementary user identification information along with the user identification information, and   wherein the control section determines whether or not the supplementary user identification information is included in the extraction bounds decided by the decision section.   
     
     
         4 . The information processing device as set forth in  claim 3 ,
 wherein the supplementary user identification information is acquired using a near field communication function with which the mobile terminal is provided.   
     
     
         5 . 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;   a communication section that transmits the location information acquired by the location information acquisition section and user identification information of a user who uses the mobile terminal to another device; and   wherein if the near field communication section receives information that represents extraction bounds decided corresponding to a distance between the location represented by the location information and a first location stored in the other device and transmitted by the another device and presence information that denotes whether or not the other user identification information that has been retrieved in the extraction bounds has been stored in the another device, the near field communication section performs near field communication with a mobile terminal identified by the other user identification information based on the information that represents the extraction bounds and the presence information that have been received.   
     
     
         6 . A communication system, comprising:
 an information processing device that comprises:
 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 the user identification information and a first location associated with the user identification information; 
 a decision section that decides extraction bounds based on a distance between the location represented by the current location information acquired by the communication section and the first location; and 
 a control section that transmits information that represents the extraction bounds decided by the decision section to a mobile terminal; and 
   a mobile terminal as set forth in  claim 5 .   
     
     
         7 . 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 an extraction bounds based on a distance between the location represented by the acquired current location information and a first location associated with the user identification information; and   transmitting information, that represents the extraction bounds decided to the mobile termi
