PROBLEM TO BE SOLVED: To realize a method for optimizing the frequency of a multilayer cellular mobile radio communication network at the time of adding an arbitrary one microcell base station for specifying a prescribed microcell belonging to the cover area of the prescribed microcell. SOLUTION: This is a communication network in which a time-division multi-dimensional connecting network(AMRT) is combined with a frequency- division multi-dimensional connection network(AMRF). Also, this communication network includes microcells 1 and 2 and microcells 3 and 4, and each of the microcells 1 and 2 is connected with at least one beacon frequency(BCCH) and at least one traffic frequency(TCH). Then, each of the microcells 3 and 4 is connected with at least one beacon frequency(BCCH). The beacon frequency(BCCH) which is the same as the traffic frequency(TCH) used by the microcell 2 directly adjacent to the microcell 1 is assigned to this microcell. |
