PROBLEM TO BE SOLVED: To easily and also adequately detect interference in the same frequency between the adjacent zones of a mobile communication system. SOLUTION: A mobile equipment performs communication with a base station 2 through the use of a frequency f1 , a communication frequency is temporarily changed-over into another frequency at every prescribed time and the electric field strength of the frequency f1 is measured by the mobile equipment 3. The base station 1 uses the same frequency f1 as that of the base station 2 and the zones of the base stations are partially superimposed. When the electric field strength of the frequency f1 is measured after the mobile equipment 3 moved into the superimposed part, high electric field strength is measured by electric wave which is transmitted from the base station 1. Thus, the usage of the frequency f1 is prohibited. |
