Abstract:
A method for use in a base station for selecting an optimal channel to support a call between said base station and a mobile subscriber unit, said method comprising the steps of:constructing a modified channel set from at least two purely homogeneous channel sets in which said modified channel set's measure of homogeneity is reduced with respect to said at least two purely homogeneous channel set's measure of homogeneity by selecting a plurality of channels of said modified channel set from said at least two purely homogeneous channel sets; prioritizing the plurality of channels in said modified channel set in accordance with a first sequence of interference measurements; ordering a selected subset of said prioritized channel set in accordance with a second sequence of interference measurements; and selecting a channel from said selected subset to support said call between said base station and said mobile subscriber unit, whereby the selected channel has a reduced measured level of interference and said cellular radio system has a greater call capacity.
