| Abstract;By integratedly transferring voice and data, application efficiency of channels could be upgraded. When applying this to multi cell systems, it is necessary to carry out channel allocation to reduce interferential power between cells. And, as voice call is required for its immediacy, it is necessary to preferentially secure the channels. As a method considering them, in this paper, was investigated a method to reduce interference between cells by preferentially carrying out data transfer on silent periods of circuit-switched-voice call using channel segregation. By computer simulation, it was shown that this method could be improved features such as interferential ratio, call loss ratio, forced disconnecting ratio, and hand-off ratio. |
