FORFARANDE FOR OVERFORING AV ADRESSKODAD INFORMATION

摘要

The present invention comprises a method of transmitting information from a central ground station to at least one mobile auxiliary ground station via at least one base station. The auxiliary ground stations are located within the transmitting range of at least one base station, and are provided with a receiving device having a control unit and a memory. In accordance with this method, a block of messages cyclically repeated within a time frame is transmitted over a single frequency from the central ground station to the base stations. Each of the messages within the block includes an address code which corresponds to the area code of the region adjacent a corresponding base station. The base stations transmit the block of messages over a single frequency to receiving devices located in the mobile auxiliary ground stations where those messages corresponding to a selected area code are recorded and then played back.
