Abstract
A system and method for performing an emergency call is disclosed that can reduce inter-cell interference. A wireless communication system for performing an emergency call includes an emergency call mobile station for requesting the emergency call; a relay mobile station for relaying the emergency call request to a serving base station; a serving base station for receiving the emergency call request via the relay mobile station, determining an emergency call transmission resource, and requesting its ambient base stations so as not to use the determined emergency call transmission resource; and ambient base stations for preventing the use of the area of the transmission resource, to which the emergency call transmission resource is allocated.
