Abstract (in Japanese) (See Japanese page) 
(in English) he relation of channel assignment problems in wireless communications and coloring problems of graph theory is well-known. A channel in the wireless communication is corresponding to a color assigned to a vertex (an edge) in a graph. It is popular to minimize the number of colors assigned to vertices of the graph. However, the maximum number of colors called Grundy Number is also important. In the previous study, we show the upper bounds of colors assigned to some graphs. And we have previously proposed a problem that extends the conventional graph coloring incorporating the degree of channel interference, and have obtained some results. In this paper, we consider the case in which the call termination is assumed in the actual channel assignment.
