<p>A method for two-way mobile radio telephone communication in a subdivided three-dimensional network is disclosed. The communication space is subdivided (100) into a three-dimensional tiling pattern consisting of basic, zero-order and higher-order cells obtained by the homothetic transformation subdivision (200) of next lower order cell. The zero-order and higher-order cells are arranged on main planes containing the centres of the zero-order cells, and intermediate planes containing the centres of the higher-order cells. The cell arrangement on the planes is defined for two adjacent cells by the homothetic ratio between the edges of consecutive-order cells and by the shortest distance between the centres of two consecutive-order cells on a single plane. A frequency group is assigned (300) to each basic and higher-order cell from a set of frequency groups, and different frequency groups are assigned to two adjacent cells. Messages are transmitted (400) using mobile radio telephones on at least one of the assigned frequencies. The method is useful in mobile radio telephone communications.</p> |
