Mobile Station Power Control

By means of the "MS Power Control" procedure /GSM:08.58:- 4.8/,
BSC gives RBS the power level to be used by MS, on a dedicated
resource.
MS power control is employed to minimise the transmit power required
by the MS while maintaining the quality of the radio links. By
minimising the transmit power levels, interference to co-channel users is
reduced.
Functionality supported:
•
•
Channel Activation function is not described here.
