Communications system with repeater stations
First Claim
1. A radio communications system including a central station and at least first and second remote stations, said central station transmitting messages each preceded by a unique address to said first and second remote stations, said system including in combination:
- first and second remote stations;
said first remote station having receiving means for receiving messages from said central station and including means for decoding a first unique address for operating utilization means at said first remote station in response to receipt and decoding of such first address, said first station also having means for decoding a second unique address for said second remote station and translating said second address to a new address for said second remote station, said first remote station including means for transmitting said new address followed by messages received by said first remote station and originally preceded by said second address to said second remote station; and
means for causing said second remote station to be responsive to said new address for operating utilization means to said second remote station and for rendering said second remote station nonresponsive to said second address transmitted from said central station.

Abstract
A radio communication system includes a polling central station and a number of remote stations. Each remote station is identified by a unique address transmitted from the central station preceding a message intended for such remote station. Each of the remote stations also may be programmed to respond to the address of a "partner" station in addition to responding to its own address. The "partner" station address is employed whenever one of the remote stations is located such that a transmission link problem exists between such station and the central station polling station. When this condition exists, the station which has difficulty communicating directly with the central station is provided with a new address and no longer is responsive to the address of messages transmitted to it from the central station. Another remote station, having a better communications link between it and the central station, then is optionally programmed to respond to the address of its "partner" station and translates that address to the new address, which precedes the relaying or retransmission of the message to the partner station. Similarly, messages from the partner station are transmitted to the relaying station, preceded by the new address and the relaying station translates the new address to the original or normal address of the partner station for retransmission to the central polling station. Thus, different ones of the remote stations optionally may be used as relaying stations as needed in the implementation of the system, without requiring any changes whatsoever in the operation of the central polling station.

5. A radio communications system including a central station and at least first and second remote stations, said central station transmitting messages each preceded by a unique address to said remote stations, said system including in combination:
-
receiving means at said first remote station for receiving messages from said central station and including means for responding to and decoding a unique address identifying messages intended for said second remote station and translating said second address to a new address for said second remote station; transmitting means at said first remote station for transmitting, to said second remote station, said new address followed by a message received by said first station and originally preceded by said second address; and means at said second remote station causing said remote station to be responsive to said new address for operating utilization means at said second remote station and for rendering said second remote station nonresponsive to said second address transmitted from said central station. - View Dependent Claims (6, 7, 8)
