Abstract
A method and system for performing power control in a mobile communication network comprising at least one base station and a network element connected to the base station, wherein a reliability information is transmitted from the at least one base station to the network element, the reliability information defining a quality of a radio transmission between the at least one base station and a mobile terminal. Based on the transmitted reliability information, the network element determines a variation of a target setpoint for power control and transmits a power control command defining the variation of the target setpoint to the at least one base station. Thereby, a bearer specific controlling procedure can be performed and the signaling of the procedure can be done via the user plane. This implementation provides an outer loop power control having the necessary flexibility to adapt its parameters to the bearer characteristic of an actual connection.
