A method performed by a control device for controlling total average transmission power of a radio base station. The method comprises performing, for a current discrete time value, control of total average transmission power according to an average power control loop and subject to an upper threshold value. The total average transmission power is computed over an averaging time window T of a present value of momentary transmission power and N−1 preceding values. This is controlled to not exceed the threshold value by a resource threshold factor that limits the momentary transmission power and by for at least one future discrete time value less than, or equal to, t+T predicting a future value of the total average transmission power for a future assumed resource threshold factor. The method comprises gradually changing this factor as a function of a present state of the control loop.

A system (500) for creating verifiable digital media, the system comprising a communication node for generating a random seed (501), a radio base station (502), and a server host (503). The communication node (501) transmits, to the radio base station (502), a random seed. The communication node (501) transmits, to the server host (503), the random seed. The server host (503) stores the random seed. The radio base station (502) transmits, to a WD, a pseudorandom number based on at least the random seed. The WD uses a private key to sign a digital media and the pseudorandom number. The WD transmits, to the radio base station (502), the digital signature, within a time interval from receiving the pseudorandom number. The radio base station (502) transmits, to the server host (503), the digital signature, and the server host (503) stores the digital signature and the metadata.
