Abstract

In a mobile communication system, two or more parallel traffic channels are allocated for high-speed data transmission over the radio path. Different channel numbers (e.g., ch0, ch1, ch2, ch3) are assigned to these parallel traffic channels for the duration of a connection. The data of a high-speed data signal are inserted at the distribution point of the transmission end of the connection, into frames, each of which is provided with a channel number indicating the parallel traffic channel used for the transmission. The frames transmitted in a traffic channel always contain the same channel number during the whole call. The frames are divided into parallel traffic channels in a sequential order according to the channel numbering. At the reception end, of the connection, the data contained in the frames are reassembled into a high-speed data signal in the sequential order according to the channel numbers provided in the frames. Additionally, frame numbering may be used within each of the traffic channels so that at least two successive frames always have a different frame number (e.g., fr0, fr1). As a consequence, the allowed delay offset between the traffic channels increase with the number of the frame numbers, and the order of the frames maintained under any circumstances.
