The invention relates to a method for controlling the function of a mobile station in a packet switched communication network based on a cellular network, which communication network is arranged to transfer information between a base station and at least one wireless communication device by means of a radio channel, wherein to transfer information, a transmission power on a set level is used on the radio channel. Information divided into successive blocks (, B-B) is transmitted from the base station to the mobile station on the radio channel. In the method, the block also contains information (PR) relating to the power level of the transmission. In the method, a block (, B-B) that is transmitted repeatedly and at fixed intervals is transmitted with a fixed transmission power to establish a reference level.

Method for indicating power consumption in a packet switched communication system

A method for power control of a wireless communication device () comprises the steps of defining the transmission power of at least one transmitter () of the wireless communication device (), defining a power index (POW) on the basis of the transmission power of the transmitter (), and selecting at least one limit value. The power index (POW) is compared with the limit value and, on the basis of the comparison, it is deduced whether there is a need to adjust the transmission power of the wireless communication device (). The transmission power may then be adjusted accordingly. A related wireless communication device and a system shown.
