Electronic device and communication control method

Abstract

According to one embodiment, an electronic device includes a communication module, a connection establishment module, a negotiation module, a service execution module, and an execution control module. The communication module executes close proximity wireless transfer. The connection establishment module establishes a connection between the communication module and an external device which are in a close proximity state. The negotiation module determines a service to be executed between the communication module and the external device through a negotiation process when the connection is established. The service execution module executes the service. The execution control module executes the negotiation process again in response to a user's request or a request from the external device if the connection is kept after the completion of the service.

1 . An electronic device comprising:
 a communication module configured to execute close proximity wireless transfer;   a connection establishment module configured to establish a connection between the communication module and an external device which are in a close proximity state;   a negotiation module configured to determine a service to be executed between the communication module and the external device through a negotiation process when the connection is established;   a service execution module configured to execute the service; and   an execution control module configured to execute the negotiation process again in response to a user's request or a request from the external device if the connection is kept after the completion of the service.   
     
     
         2 . The electronic device of  claim 1 , wherein the execution control module is configured to wait for transmitting a start request of the negotiation process until receiving the user's request, after the completion of the service. 
     
     
         3 . The electronic device of  claim 1 , further comprising a flag setting module configured to set a flag indicative of the completion if the execution of the service is completed and to reset the flag in response to the user's request or the request from the external device if the connection is established,
 wherein the execution control module is configured to execute the negotiation process again in response to the resetting of the flag.   
     
     
         4 . An electronic device comprising:
 a communication module configured to execute close proximity wireless transfer;   a connection establishment module configured to establish a connection between the communication module and an external device which are in a close proximity state;   a negotiation module configured to execute a negotiation process including a process of determining whether the external device is in a first mode in which the external device transmits a service start request to a communication target device or in a second mode in which the external device receives a service start request from the communication target device if the connection is established, a process of receiving the service start request from the external device set to the first mode, and a process of transmitting the service start request to the external device set to the second mode and determining a service to be executed between the communication module and the external device;   a service execution module configured to execute the service; and   an execution control module configured to execute the negotiation process again in response to a user's request or a request from the external device if the connection is kept after the completion of the service.   
     
     
         5 . The electronic device of  claim 4 , wherein the negotiation module is configured to transmit the service start request to the external device set to the second mode, to receive information indicative of services that can be executed by the external device, and to determine a service selected from the services to be executed between the communication module and the external device and
 the execution control module is configured to execute the negotiation process again in response to a user's request or a request from the external device if the connection is kept after the completion of the service.   
     
     
         6 . The electronic device of  claim 4 , wherein the negotiation module is configured to receive a service start request from the external device set to the first mode, to receive information indicative of a service specified by the external device, and to determine the service to be executed between the communication module and the external device and the execution control module is configured to execute the negotiation process again in response to a user's request or a request from the external device if the connection is kept after the completion of the service. 
     
     
         7 . The electronic device of  claim 4 , wherein the negotiation module is configured to transmit a service start request to the external device in response to the user's request, and to determine a service specified in the user's request to be executed between the communication module and the external device, and
 the execution control module is configured to execute the negotiation process again in response to a user's request or a request from the external device if the connection is kept after the completion of the service.   
     
     
         8 . The electronic device of  claim 4 , further comprising a flag setting module configured to set a flag indicative of the completion if the execution of the service is completed and to reset the flag in response to the user's request or the request from the external device if the connection is established,
 wherein the execution control module is configured to execute the negotiation process again in response to the resetting of the flag.   
     
     
         9 . A communication control method of controlling communication between an external device and an electronic module comprising a communication module executing close proximity wireless transfer, the method comprising:
 establishing a connection between the communication module and the external device which are in a close proximity state;   determining a service to be executed between the communication module and the external device through a negotiation process when the connection is established;   executing the service; and   executing the negotiation process again in response to a user's request or a request from the external device if the connection is kept after the completion of the service.
