Electronic device and communication system for mediating establishment of communication between plurality of communication devices

An electronic device capable of mediating establishment of communication between a first communication device and a second communication device, the electronic device comprising:

• a communication unit configured to communicate with the first communication device or the second communication device;
• and
• a controller configured to control the communication through the communication unit, wherein
• when the electronic device is within a predetermined distance to the first communication device, the controller transmits predetermined additional information to the first communication device through the communication unit, and when the electronic device is within a predetermined distance to the second communication device, the controller transmits the predetermined additional information to the second communication device through the communication unit, and
• the predetermined additional information can be used by the second communication device to activate an operation for establishing communication with the first communication device having the predetermined additional information, when the second communication device receives the predetermined additional information.

A method for establishing communication between a first communication device and a second communication device via an electronic device, the method comprising:

• obtaining, by the electronic device, identification information indicating the first communication device from the first communication device, when the electronic device is within a predetermined distance to the first communication device;
• transmitting, by the electronic device, the identification information and predetermined additional information to the second communication device, when the electronic device is within a predetermined distance to the second communication device;
• and
• the identification information and the predetermined additional information can be used by the second communication device to perform an operation for establishing communication with the first communication device indicated by the identification information.
