Patent ID: 6891800

Claim:
A method for controlling data flow of terminals in a centrally controlled communication system including a central station (ZE) for controlling the communication system, said method comprising allocating transmission resources to the terminals (T 1 , T 2 , . . . ) of the communication system by the central station (ZE) according to the following steps: a) a terminal (T 1 , T 2 , . . . ) requiring the transmission resources makes a decision whether or not to use only reduced transmission resource capacity at least in transmission therefrom, independently of available transmission resources; b) the decision rewarding the reduced transmission resource capacity is transmitted from the terminal making the decision to the central station (ZE) so that the central station (ZE) allocates any remaining unused transmission resource capacity, as needed, to other terminals of the communication system; and inserting information entities in a transmission frame of a resource requirement message (RR) of said terminal (T 1 , T 2 , . . . ) to the central station, wherein said resource requirement message informs the central station about a required or intended capacity, and wherein said information entities signal a reduced amount of transmission possibilities during at least one of an up-link phase and a direct-mode phase.
