System for sharing content between electronic devices, and content sharing method for electronic device

An electronic device comprising:

• a communication module;
• a memory configured to store contents;
• and
• a processor configured to control to:
• transmit a command requesting devices information to a machine-to-machine communication system in response to an input for sharing contents,
• receive the devices information from the machine-to-machine communication system,
• select a first external electronic device which to transmit the contents of the electronic device based on the devices information,
• determine a communication mode between the electronic device and the first external electronic device based on content information to be shared and the devices information,
• transmit at least part of the contents to a second external electronic device using the communication module based on the determined communication mode being a first communication mode, wherein the second external electronic device is connected to the first external electronic device, and
• transmit the at least part of the contents to the first external electronic device using the communication module based on the determined communication mode being a second communication mode,
• acquire integrated resource access information supporting external access corresponding to the at least part of the contents transmitted based on the first communication mode, from the second external electronic device, and
• transmit the integrated resource access information to the first external electronic device.
