Abstract: An apparatus is capable of reducing an overhead caused by a mute section in a wireless communication system that provides a Voice over Internet Protocol (VoIP) service. In the method, one or more terminals for providing the VoIP service during a next time section are determined. Mute section set information of a current time section and the next time section for the one or more terminals is determined. An amount of a resource of the next time section is allocated to at least one terminal whose next time section is not set to a mute section, wherein the amount of resource of the next time section is based on whether the current time section is set to a mute section or not set to a mute section.

In the method, one or more terminals for providing the VoIP service during a next time section are determined. Mute section set information of a current time section and the next time section for the one or more terminals is determined. An amount of a resource of the next time section is allocated to at least one terminal whose next time section is not set to a mute section and whose current time section is set to a mute section among the one or more terminals such that the amount of the resource of the next time section is smaller than an amount of a resource of a current time section.
