Transmission method and radio system

A radio system which comprises a base transceiver station acting as a transceiver and subscriber terminals acting as transceivers which establish a connection with each other with a signal transmitted through the base transceiver station, for which connection a radio channel is formed, in which a signal coded by the transceiver is transmitted, and in which radio system the transceiver comprises transmission means which transmit frames when the transceiver is in DTX mode, the radio system comprising:

• a measuring means which measure the signal received by the transceiver from the radio channel,
• a transmission means which transmits during DTX information in frames to the radio channel on the basis of a measurement result obtained from the measuring means, of which frames at least some are freely placed by the transmission means anywhere in the frame structure to be transmitted, after which
• the transmission means transmit the frames to the transceiver which is connected to a transceiver in DTX mode, and the transceiver receiving the frames alters its operation on the basis of the information in the frames.

The radio system as claimed in claimed in 11, wherein the transceiver in DTX mode is a base transceiver station which transmits frames to a transceiver which is a subscriber terminal.
