Patent number: 6917811Abstract: Provided is a real-time dynamic channel assignment method based on a genetic algorithm in a radio communication system, and a computer-readable recording medium for recording a program implementing the method. The channel assignment method in accordance with the present invention has following advantages. First, an evaluation function clearly shows the difference between chromosomes, which represents channel assignment, can be set. Second, the efficiency in calculation time and memory capacity is increased by representing the assignment of channels arranged in one-dimensional using inherent channel numbers. Third, by controlling the Elitist pool crossover method and mutation probability properly, diversity is pursued in the initial process of the evolution program, and then as generation repeats, the convergence is enhanced so as to increase the efficiency in obtaining the optimum solution.Type: GrantFiled: December 24, 2002Date of Patent: July 12, 2005Assignee: KT CorporationInventors: Sang Taek Kim, Jong Hyun Lee, In Hwan Hwang, Sung Soo Kim, Kwang Jin Han
