Device and method for performing inter-device communication

A method and device for performing inter-device communication are disclosed. The inter-communication method according to the present invention comprises the following steps of: searching for a second device supporting inter-communication, and receiving service information from the searched second device; comparing the received service information of the second device to service information of a first device, and determining that one of the first and second devices is a group owner and the other device is a group client; receiving a group owner intent value from the second device; and setting a group owner intent value of the first device so that the group owner intent value of the device determined as a group owner is greater than the group owner intent value of the device determined as a group client by comparing the group owner intent value of the first device to the group owner intent value of the group owner intent value.
