Cellular communications systems

摘要

A method of operating a cellular communications system comprising at least one macro cell having a macro cell base station and at least one micro cell having a micro cell base station, at least part of the micro cell being located within an area served by the macro cell base station, which method comprises the steps of: (I) receiving an electronic indication representative of the quality of service at one or more cellular communications devices served by the macro cell base station; (2) electronically processing the or each electronic indication to obtain a comparison with a predetermined threshold for said quality of service; and (3) electronically controlling signals emitted from the micro cell base station in response to said comparison such that the quality of service of any cellular communication device(s) served by the macro cell base station that are within a predetermined range of the micro cell base station exceeds said predetermined threshold so as to permit the transmission and reception of data in the micro and macro cells on substantially the same frequency band(s).
