Portable terminal, portable terminal operation system, and communication control method

A portable terminal for providing a portable terminal operation system together with a controller that starts transmission of a connection standby packet when receiving a disconnection request from an external device and ends the transmission of the connection standby packet when receiving a connection request from the external device, the portable terminal comprising:

• a disconnection request transmission device that transmits the disconnection request to the controller when notified that an application body of a cooperative application shifts to a background in a case where an interrupt request from a different application or a body of the portable terminal generated while the cooperative application is running;
• and
• a connection request transmission device that starts monitoring of reception of the connection standby packet from the controller when notified that the application body of the cooperative application shifts to a foreground, and transmits the connection request to the controller when receiving the connection standby packet from the controller.

A communication control method for a portable terminal providing a portable terminal operation system together with a controller that starts transmission of a connection standby packet when receiving a disconnection request from an external device and ends the transmission of the connection standby packet when receiving a connection request from the external device, the communication control method comprising:

• transmitting the disconnection request to the controller when notified that an application body of a first cooperative application shifts to a background in a case where a start request for a second cooperative application is generated while the first cooperative application is running;
• and
• starting monitoring of reception of the connection standby packet from the controller when notified that the second cooperative application has been started in a case where the start request is notified from the application body of the first cooperative application to an application body of the second cooperative application, and transmitting the connection request to the controller when receiving the connection standby packet from the controller.
