Method and apparatus for communication between application programs

A computer-readable storage medium storing a computer-executable program, the computer-executable program causing a computer to execute a method for communicating, the method comprising:

• receiving a transmission message to be transmitted from a first application to a second application;
• searching for the second application in the same area that the first application is present;
• transmitting the transmission message as it is from the first application to the second application if the second application has been found in the same area as the first application;
• searching for the second application in an area different from the area of the first application if the second application has not been found in the same area as the first application;
• encoding the transmission message if the second application has been found in the area different from the area of the first application;
• and
• transmitting the encoded transmission message from the first application to the second application if the second application has been found in the area different from the area of the first application.

A communication system implemented by a computer system, comprising:

• a reception unit configured to receive a transmission message to be transmitted from a first application to a second application;
• a first search unit configured to search for the second application in the same area as the first application is present;
• a first transmission unit configured to transmit the transmission message as it is from the first application to the second application if the second application has been found in the same area as the first application;
• a second search unit configured to search for the second application in an area different from the area of the first application if the second application has not been found in the same area as the first application;
• an encoding unit configured to encode the transmission message if the second application has been found in the area different from the area of the first application;
• and
• a second transmission unit configured to transmit the encoded transmission message from the first application to the second application if the second application has been found in the area different from the area of the first application.
