ABSTRACT:
A radiotelephone communication system is provided, in which radio communication channels including control channels and a plurality of communication channels are set between a plurality of base stations and a plurality of mobile stations provided within radio zones of the base stations, an outgoing call and an incoming call are controlled and the communication channels are designated via the control channels, a telephone conversation is made via the communication channels, channels of different frequencies are allocated to adjacent radio zones of the radio zones, each base station includes a circuit for detecting receiving electric field intensity of mobile station and the channel, the base station and operation of radio transmitter and receiver of the mobile station are set such that, when the mobile station is moved between the radio zones, the mobile station is constantly connected to the base station whose communication state is satisfactory. In this radiotelephone communication system, the mobile station is comprised of a circuit for detecting receiving electric field intensities of transmission signals of the plurality of base stations, a memory for storing data associated with detected receiving electric field intensity, and a circuit for transmitting an information associated with the data to the base stations via a up-channel, wherein the base station analyzes the information associated with the data transmitted from the mobile station and sets a transmission power of a mobile station which transmits the data or receiving and transmitting conditions between the radio zones in response to the analyzed result.
