Abstract:
1. A method for repeat transmission of messages in a centrally controlled communication network, in which several terminals (T 1 , T 2 , . . . ) are simultaneously configured to operate, said method comprising: a) transmitting each of said messages once from a central station (ZE) for reception by each of said terminals (T b) as soon as one of said terminals (T c) said central station (ZE) performs repeat transmissions of said one of said messages with said one of said sequence numbers (SN) in response to the repeat request, but only within a predetermined time interval; d) halting said repeat transmissions of said one of said messages within said predetermined time interval when a predetermined maximum number of repeat transmission of said one of said messages has been reached within said predetermined time interval; and e) halting said repeat transmissions of said one of said messages within said predetermined lime interval when a positive acknowledgement of receipt of said one of said messages is received by said central station during said predetermined time interval from said terminal issuing said repeat request; whereby clogging of said communication network by said repeat transmissions is effectively prevented.
