Abstract: Disclosed is a resource allocation technology using inter-cell interference separation, which can increase a voice over Internet protocol (VoIP) capacity by efficiently managing VoIP resources through minimization of inter-cell interference. A method for allocating resources using the inter-cell interference separation according to the present invention, in which a base station allocates a packet of each of multiple terminals to a frequency resource in a preset cell, comprises the following steps: assigning, by the base station, an allocation priority to allocate a packet of each of multiple terminals to a frequency resource in consideration of intensity of a signal received from each of the multiple terminals and intensity of interference from a base station of an adjacent cell interfered most by the multiple terminals; defining an in-band of the frequency resource to which a preset number of packets with high allocation orders of priority among the packets are allocated; allocating the preset number of packets with high allocation orders of priority to the in-band; and allocating, in consideration of an in-band of the adjacent cell, remaining packets to an area of the frequency resource apart from the in-band of the adjacent cell.
