In the future, stricter standards regarding the microwave radiation emitted by mobile telephones will be applied. Therefore, in the worst case, the transmission power of mobile telephone systems will have to be reduced, which will affect the quality of service. However, it would be unreasonable to reduce the transmission power of all mobile stations. Therefore, the object of the invention is to create e.g. in the GSM system a property that allows a mobile station to be used at a power level consistent with the safety standards. The invention makes it possible to distinguish between different mobile stations e.g. on the basis of their IMSI and/or IMEI codes. According to the invention, data substantially relating to the transmission power of the mobile station are stored in the mobile communication network separately for each mobile station; device data identifying the mobile station are received in the mobile communication network in conjunction with call setup; the transmission power data for the mobile station are checked and the transmission power of the mobile station is controlled on the basis of a predetermined power control algorithm and the device data for the mobile station. |
