Abstract

The invention relates to a data transfer method and a transceiver equipment in a digital mobile network, in which the information to be transmitted is channel coded for the transmission. In the current 4800 bit/s data transfer service of the mobile network, information bits to be transmitted are block coded (31) to a block of 152 bits, which block is convolutional coded (32) at the ratio 1/3 into a block of 456 bits. The block of 152 bits contains, besides the information bits, fill bits having no effect on the error correction performance. These fill bits are overhead capacity in the nominal bit rate of the radio interface traffic channel point of view. In the present invention, this overhead capacity is used for supporting a new 7200 bit/s user rate. Then the number of information bits is increased and the number of fill bits is decreased in a 152 bit frame (62) in such a way that the user rate before block coding (31) increases, but the data rate before convolutional coding (32) remains unchanged. Consequently, the same 1/3 convolutional coding can be used for the 7200 bit/s user rate as is used for the 4800 bit/s user rate.
