Method for real-time data transmission in a communication network

摘要

A method for real-time data transmission in a communication network for transmitting useful data from a transmitter to a plurality of receivers, wherein the receivers are synchronized in terms of time via a synchronization method, at least one time for transmitting a respective useful data message to the receivers is stipulated during real-time data transmission, each of the receivers is assigned its own receiver useful data area within the useful data message, which area is assigned to the receiver, and the transmitter transmitting a useful data message. In accordance with the invention, a first of the receivers receiving this useful data message, stores the useful data contained in the receiver useful data area assigned to it for further processing, and forwards the useful data message to a second of the receivers at the transmission time.

1. A method for real-time data transmission in a communication network for transmitting useful data from a transmitter to a plurality of receivers, the receivers being synchronized in terms of time via a synchronization method, the method comprising:
stipulating at least one transmission time for transmitting a respective useful data message to the plurality of receivers during real-time data transmission, said at least one transmission time having an accuracy or tolerance period determined by at least one of (i) propagation times of individual receivers and transmitters and (ii) accuracies of the individual receivers and transmitters, and at least one receiver or at least one transmitter, or a plurality of the individual receivers and transmitters, said at least one transmission time being communicated to each of the plurality of receivers in one of an information message or planning message during the realtime data transmission or non-realtime data transmission, said information or planning messages further comprising information relating to receivers of a useful data message or a sequence for forwarding or transmitting the useful data message to the different receivers; assigning each of the plurality of receivers to a respective receiver useful data area within the respective useful data message such that a respective receiver useful data area is assigned to a respective receiver of the plurality of receivers; transmitting, by the transmitter, the respective useful data message;
receiving, at a first receiver, the respective useful data message; storing, at the first receiver, the received useful data contained in the receiver useful data area assigned to the first receiver for further processing; and forwarding the received useful data message to a second receiver of the plurality of the receivers at the at least one transmission time; wherein the transmitter and the plurality of receivers are synchronized in terms of time; and wherein the transmitter transmits the useful data message within a period of time assigned to the real-time data transmission.
