Abstract

Abstract An information transmission system includes a base station (1) and a relay station (2), in which diagnosis data of an erroneous information signal is stored in a memory (25), and the diagnosis data is transmitted to the base station (2) in response to a diagnosis return instruction sent from the base station (2). According to a further aspect of the invention, an error correction code (ECC) is added to each packet and an error correction code for an identification code including a relay station indicating code is also added in the base station. In relay stations, error correction of the identification code is performed before the error correction of the packets.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 71 words
An information transmission system having a base station for transmitting an information signal and a relay station for receiving said information signal, said relay station comprising: detector means for detecting errors in said information signal and producing error diagnosis data; a memory for storing said diagnosis data; and transmission means for transmitting said diagnosis data to the base station in response to a diagnosis return instruction sent from said base station.
Claim 2
Dependent Claim 33 words
An information transmission system according to claim 9, wherein said transmission means transmits said diagnosis data to said base station via a transmission path different from a transmission path for said information signal.
Claim 3
Dependent Claim 130 words
An information transmission system comprising a base station for transmitting a digital information signal and a plurality of relay stations for receiving said information signal, said base station including: dividing means for dividing said digital information signal into packets of a predetermined amount of information; and inserting means for inserting first correction code bits for error correction and an identification code including relay station indicating codes of designated relay stations into each of the packets, with second correction code bits for self error correction being included in the identification code, and each of said relay stations including: extracting means for extracting said identification code from received packets; and error correction means for performing error correction on said identification code acquired by said extracting means using said second correction code bits.
Claim 4
Dependent Claim 14 words
The system of claim 3 , wherein said digital information signal is weather information.
Claim 5
Dependent Claim 22 words
The system of claim 3 or 4, wherein said relay station further comprising means for transmitting correction information to said base station.
