FIELD: radio communications.
SUBSTANCE: radio network controller sends value of power deviation for controlling power of transfer of high-speed dedicated physical control channel of ascending communication line, when user equipment enters service transfer zone, in cell communication system, containing radio network controller, assembly B, connected to said controller and user equipment, being in one of at least two cell nodes, occupied by assembly B. assembly B sends data to user equipment via high-speed jointly used channel of descending communication line and user equipment transfers data, notifying about data receipt state, to assembly B along ascending communication line. Controller sends to user equipment a value of deviation of power to determine transmission power adjustment for ascending communication line, if it is determined, that user equipment is within limits of service transfer zone. Controller sends to assembly B value of power deviation, to allow assembly B to determine threshold value for data determining, noting data receipt state, dependently on power deviation.
EFFECT: high-speed data delivery to user equipment.
