Abstract

The present invention relates to a radio server system. The communications service area of this radio server system is made of a plurality of zones and the radio server system connects to the Internet via a radio server in which a mobile radio is connected to a base station radio by carrying out data communications between base station radios in each of the zones and a plurality of mobile radios such that the base station radio continuously sends data and the mobile radio sends a burst signal to the base station radio, wherein the base station radio communicates using a single frequency that is different from the frequency used by neighboring base station radios, and each mobile radio detects the frequency used by the base station radio in the base station radio'"'"'s zone and communicates with the base station radio using the detected frequency.

Claims

1. A base station radio in a radio server system having a communications service area that includes a plurality of zones, and being connecting to Internet via a radio server in which a mobile radio of a plurality of mobile radios is connected to a base station radio of a plurality of base station radios by data communications between base station radios disposed in each of the zones and the plurality of mobile radios, such that the base station radio continuously sends data using a single frequency that is different than frequencies used by neighboring base stations, the mobile radio positioned in a zone covered by said base station radio and is configured to send a burst signal to the base station radio, wherein said base station radio comprising:

a memory configured to hold up and down frequency values received from an external source and used by said base station radio, and down frequencies used by the neighboring base station radios;

a ROM configured to hold the single frequency; and

a determination mechanism configured to determine whether on not the frequencies received from the external source are presently usable by comparing the up and down frequencies recorded in said memory with the single frequency recorded in said ROM, wherein said base station radio configured to use the down frequency to send the up frequency used by said base station radio and the down frequency used by the neighboring base station radio, when said determination mechanism determines that said received frequencies can be used.

2. A base station radio in a radio server system employing a two-frequency simplex operation in which a communications service area includes a plurality of zones, the radio server system connecting to the Internet via a radio server in which a mobile radio is connected to the base station radio by carrying out data communications, comprising:

a memory configured to receive and hold from an external source up and down frequencies used by said base station radio, and a down frequency used by base station radios disposed around said base station radio, said base station radio being configured to communicate data with said mobile radio using a single frequency that is different than frequencies used by the base stations disposed around the base station and said mobile radio being configured to transmit a burst signal to said base station;

a ROM configured to record a frequency at which said base station radio can transmit and receive; and

a determination mechanism configured to determine whether the frequencies received from the external source can be used by comparing the up and down frequencies used by said base station radio and recorded in said memory with the frequency that is recorded in said ROM, wherein

said base station radio using the down frequency to send the up frequency used by said base station radio and the down frequency used by neighboring base station radios, when said determination mechanism determines that said received frequency can be used.
