<p><P>PROBLEM TO BE SOLVED: To make a call reception determining method based on a virtual buffer/trunk model system applicable to a network node onto which priority control is performed, and to expand the method so as to guarantee qualities of a plurality of classes. <P>SOLUTION: The call reception determining method comprises constituting a set of a flow of preferential classes for a novel reception call and a flow of preferential classes with priority higher than that of the preferential classes, and determining virtual maximum buffer capacitance (S3, S4); constituting a set of a flow of the present class and a flow of preferential classes with priority higher than that of the present class similarly also for the class with priority lower than that of the preferential classes, and sequentially determining virtual maximum buffer capacitance (S6-S9); and determining whether novel reception is enabled or not (S12, S13), on the basis of whether the virtual maximum buffer capacitance of the preferential classes for the novel reception call and each of the classes with priority lower than that of the preferential classes exceeds buffer quantity provided for each class (S5, S10). <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
