Abstract
The invention relates to controlling transmission power and carrying out a handover during a data transmission over the radio path between a mobile station and a base station (BTS) in a mobile telecommunications system. A mobile station can be allocated at least two traffic channels for a high-speed data transmission. The mobile station is arranged to measure the characteristics of the received signal, such as the signal level and/or quality, in each of the allocated traffic channels. The radio network is arranged to control the transmitting power of the mobile and base stations and make the decision on a handover on the basis of a combination of measurement results of two or more traffic channels, or on the basis of the measurement result of the poorest traffic channel.
