Service providing apparatus, service providing program and service providing method

Abstract

A service providing apparatus has a first communication unit, a connection information generator, an existence detector, an existence confirmation request receiver, a connection information transmitter, an authentication unit, and a service providing unit. The second communication unit performs wireless communication with the service receiver located in a second wireless area narrower than a first wireless area. The existence confirmation request receiver receives the existence confirmation request signal transmitted by the service receiver through the second communication unit when the service receiver detects to be within a prescribed distance. The service providing unit connects with the service receiver authenticated by the authentication unit, and provides services to the service receiver through the first communication unit.

1 . A network system comprising a service providing apparatus and a service receiver which perform wireless communication to each other
 wherein the service providing apparatus comprising;   a first communication unit configured to perform wireless communication with a service receiver located within a first wireless area;   a second communication unit configured to perform wireless communication with said service receiver located within a second wireless area narrower than said first wireless area   a connection information generator which generates connection information necessary to the communication with said service receiver when the communication is performed through said first communication unit;   an existence detector which detects whether or not said service receiver locates within a prescribed distance;   an existence confirmation request receiver which receives an existence confirmation request signal transmitted by said service receiver, through said second communication unit when detected that said service receiver is located within the prescribed distance;   a connection information transmitter which transmits the connection information generated by said connection information generator to said service receiver through said second communication unit as a reply of said existence confirmation request sign at an authentication unit configured to authenticate said service receiver which requested connection based on the transmitted connection information, through said first communication unit; and   a service providing unit configured to connect with said service receiver authenticated by said authentication unit and provide the services to said service receiver through said first communication unit.   
   
   
       2 . The network system according to  claim 1 ,
 wherein the service providing apparatus further comprising a first message generator which generates a message notifying that the existence confirmation request signal from said service receiver can be received,   
   
   
       3 . The network system according to  claim 1 ,
 wherein the service providing apparatus further comprising a second message generator which generates a message notifying that the connection request from said service receiver can be received.   
   
   
       4 . The network system according to  claim 1 ,
 wherein the service providing apparatus further comprising a third message generator which generates a message notifying that connection processing with said service receiver has been completed.   
   
   
       5 . The network system according to  claim 1 ,
 wherein the service providing apparatus further comprising a measurement unit configured to measure the number of said service receivers which has performed the connection request within a prescribed time; and   an authentication determination unit configured to determine whether or not to perform authentication procedure by authentication unit in accordance with the number measured by said measurement unit.   
   
   
       6 . The network system according to  claim 1 ,
 wherein the service providing apparatus further comprising a fourth message generator which generates a message notifying that the number of said service receivers is two or more.   
   
   
       7 . The network system according to  claim 1 ,
 wherein the service providing apparatus further comprising a measurement unit configured to measure the number of said service receivers which perform connection request within a prescribed time; and   an individual authentication unit configured to authenticate said service receivers which has performed the connection request, if the number of said service receivers measured by said measurement unit is two or more, before said authentication unit performs the authentication.   
   
   
       8 . The network system according to  claim 1 ,
 wherein the service providing apparatus further comprising a distance detector which determines whether or not a distance from said service receiver is within a prescribed length,   wherein said connection information transmitter transmits the connection information to said service receiver if said distance detector determines to be within the prescribed length.   
   
   
       9 . The network system according to  claim 1 ,
 wherein the service providing apparatus further comprising a distance detector which determines whether or not a distance from said service receiver is within a prescribed length, after the connection request is received from said service receiver through said first communication unit,   wherein said authentication unit performs the authentication procedure if said distance detector determines to be within the prescribed length.   
   
   
       10 . The network system according to  claim 8 ,
 wherein said distance detector detects the distance from said service receiver by measuring a radio field intensity of a radio wave transmitted from said service receiver.   
   
   
       11 . The network system according to  claim 9 ,
 wherein said distance detector detects the distance from said service receiver by measuring a radio wave intensity of a radio wave transmitted from said service receiver.
