FIELD: mobile communications.
SUBSTANCE: radio network controller determines maximal delay time and sends data to assembly B and user equipment. Assembly B receives maximal delay time and sends data to client equipment; repeatedly sends data and at the same time sets maximal delay time for detecting query from client equipment for repeated data transfer; prevents repeated data transfer after detecting second query from client equipment for repeated data transfer, being a result of incorrect receipt of repeatedly sent data, after passing of maximal delay time. Client equipment receives maximal delay time; transfers a query to assembly B for repeated data transfer and at the same time sets maximal delay time, if there is an error in data received from assembly B; awaits repeatedly sent data only during maximal delay time.
EFFECT: prevented cases of unnecessary repeated transfer.
