Abstract

The invention relates to a data transmission method and a radio system comprising a number of transceivers (110, 120, 130, 140) and at least one subscriber terminal (400) which transmits a number of access bursts on its traffic channel during handover. In the radio system, a connection between a transceiver and a subscriber terminal is set up when the transceiver receives from its random access channel an access burst transmitted by the subscriber terminal (400), the reception of said access burst activating the allocation of a channel used for the connection. The radio system comprises means (260) for measuring the bursts received by the transceiver from the random access channel, means (250) for generating a handover reference signal which deviates from the bit pattern of the random access burst and which is transmitted to the treansceiver during handover, whereupon it is possible for the means (260) to filter off the handover reference signal received in order to prevent the allocation of a channel.
