         4 . The method according to  claim 1 , wherein the preset geographic location range refers to a range in which a connection can be established between the terminal device and the service system using a near field communication (NFC) protocol. 
     
     
         5 . The method according to  claim 1 , wherein the initiating a broadcast message to each service system comprises initiating the broadcast message to each service system located within the preset geographic location range every preset first time interval. 
     
     
         6 . The method according to  claim 1 , wherein the initiating a broadcast message to each service system comprises initiating the broadcast message to each service system located within the preset geographic location range upon receiving of a user's detection instruction. 
     
     
         7 . The method according to  claim 1  further comprising:
 sending, by an application that has already been installed in the terminal device, a display message to a service system corresponding to the application every preset second time interval; and 
 determining a display state of the application according to a display response message returned by each service system. 
 
     
     
         8 . The method according to  claim 7 , wherein:
 the display state comprises a first display state and a second display state;   the determining the display state of the application according to the display response message returned by each service system comprises:
 displaying an application, which is corresponding to a service system that returns a display response message, in the first display state; and 
 displaying an application, which is corresponding to a service system that does not return a display response message, in the second display state. 
   
     
     
         9 . The method of  claim 1 , wherein when the broadcast message is initiated to each service system, determining, according to response messages returned by all the service systems, a display state of each application that has already been installed in the terminal device. 
     
     
         10 . The method according to  claim 9 , wherein:
 the display state comprises a first display state and a second display state;   the determining, according to response messages returned by all the service system, the display state of each application that has already been installed in the terminal device comprises:
 displaying an application, which has already been installed in the terminal device and is corresponding to a service system that returns a response message, in the first display state; and 
 displaying an application, which has already been installed in the terminal device and is corresponding to a service system that does not return a response message, in the second display state. 
   
     
     
         11 . The method according to  claim 1  further comprising:
 generating an application use list according to a situation of a user's use of an application. 
 
     
     
         12 . A terminal device comprising:
 a sending module configured to initiate a broadcast message to each service system located within a preset geographic location range, so that each service system returns a response message;   a determining and sending module configured to determine whether an application corresponding to the response message returned by a service system has already been installed in the terminal device, and when an application corresponding to a response message returned by the service system is not installed in the terminal device, send a download request to a server; and   a downloading and installing module configured to download and install the application according to download information sent by the server.   
     
     
         13 . The terminal device according to  claim 12 , wherein:
 the broadcast message carries a terminal device identifier and a user identifier that are used by the service system to identify a terminal device that sends the broadcast message and a user who sends the broadcast message, respectively;   the response message carries a service type and a service identifier of the service system and a uniform resource locator (URL) address of an application store, so that the terminal device determines whether an application corresponding to the service type and the service identifier has already been installed, and when the application corresponding to the service type and the service identifier is not installed in the terminal device, sends a download request to the server according to the URL address; and   the download request comprises a service type and a service identifier of a service system corresponding to the application that is not installed, so that the server searches for the application corresponding to the service type and the service identifier.
