Abstract  Abstract

A channel configuration of a digital mobile communications system comprises two or more lower-rate transmission channels for each high-speed radio interface traffic channel between a base station and an interworking function. Radio frames such as EDGE frames are transmitted over a radio interface traffic channel. Transmission frames such as TRAU frames are transmitted on a transmission channels. The base station and the interworking function provide the transmission frames to be transmitted with frame and/or channel numbering which indicates the order of the transmitted frames and/or the transmission channel via which the transmission frame was transmitted. According to the invention the base station does not restore the order of the downlink transmission frames on the basis of said frame and/or channel numbering but it places the data of the transmission frames and at least the frame and/or channel numbering in the payload of the downlink radio frame to be transmitted. Instead the mobile station which extracts the data and the frame and/or channel numbering of the transmission frames from the downlink radio frames restores the correct order of the data on the basis of this numbering. The invention simplifies the structure of a base station.
