Abstract
A method and an arrangement for controlling transmitting power of a mobile station and carrying out a handover in a mobile telecommunications system in which data is transmitted over the radio path between a mobile station and a base station as bursts in time slots of successive frames. A mobile station can be allocated at least two time slots in each frame for 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 time slot allocated to the mobile station, and the fixed radio network is arranged to control the transmitting power of the mobile station and/or make the decision on a handover on the basis of a combination of measurement results of two or more time slots, or on the basis of the measurement result of the poorest time slot.
