Control method for plural base stations

Abstract

Abstract PURPOSE:To prevent the deterioration of quality of communication by comparing the result of detection set from respective base stations and selecting a sole base station giving the maximum incoming electric field or the highest communication quality or any of base stations giving a prescribed incoming electric field or over or a prescribed talking quality or over to keep the communication. CONSTITUTION:As a method sectioning a noise level, e.g., a monitor receiver demodulation output is amplified up to a prescribed level and rectified into a DC voltage, it is sectioned in several steps and they are identified and a tone signal has to be generated in response to the respective sectional voltage. The processing above is executed not only in a base station 6-1 but also in all base stations having an incoming signal. The tone signal sent in this way is collected in a centralized controller 7, a noise level in each monitor receiver demodulation output is compared by identifying each tone signal frequency and a minimum noise level is discriminated to be the highest incoming electric field. The operator operates a base station selection switch 9 to send an antenna switching signal only to a base station relating to the maximum incoming electric field.
