Abstract
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 are assigned to these parallel traffic channels for the duration of the connection. The data of a high-speed data signal is inserted at the distribution point of the transmission end 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 channel in the sequential order according to the channel numbering. At the reception end the data contained in the frames is reassembled into a high-speed data signal in the sequential order according to the channel numbers in the frames. Frame numbering may be used within each of the traffic channels so that at least two successive frames always have a different frame number. Consequently, the allowed delay offset between the traffic channels will increase with the number of the frame numbers, and the order of the frames will be maintained under any circumstances.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
167 words
A method for high-speed data transmission in a digital mobile communication system in which method data is transmitted over the radio path between a mobile station and a fixed mobile communication network in a traffic channel allocated to the mobile station, the method comprising: allocating a high-speed data signal at least two parallel traffic channels having mutually different channel numbers assigned for the duration of a connection, when a data transmission rate required by the data signal exceeds a maximum transmission rate of one traffic channel; inserting the data from the high-speed data signal into frames at the transmission end, each frame being provided with a channel number indicating the parallel traffic channel used for the transmission; dividing the frames into parallel traffic channels in a sequential order according to channel numbering and transmitting them to the reception end; and reassembling the data in the frames into a high-speed data signal in the sequential order indicated by the channel numbers in the frames at the reception end.
Claim 2
Independent Claim
167 words
A method for high-speed data transmission in a digital mobile communication system in which method data is transmitted over the radio path between a mobile station and a fixed mobile communication network in a traffic channel allocated to the mobile station, the method comprising: allocating a high-speed data signal at least two parallel traffic channels having mutually different channel numbers assigned for the duration of a connection, when a data transmission rate required by the data signal exceeds a maximum transmission rate of one traffic channel; inserting the data from the high-speed data signal into frames at the transmission end, each frame being provided with a channel number indicating the parallel traffic channel used for the transmission; dividing the frames into parallel traffic channels in a sequential order according to channel numbering and transmitting them to the reception end; and reassembling the data in the frames into a high-speed data signal in the sequential order indicated by the channel numbers in the frames at the reception end.
Claim 3
Dependent Claim
88 words
A method according to claim 1, further comprising: using frame numbering inside each of the traffic channels so that at least two successive frames always have a different frame number, whereby the maximum delay offset between the traffic channels increases in proportion to the number of the frame numbers as compared with the absence of the frame numbering; and reassembling the data in the frames into a high-speed data signal in the sequential order indicated by the channel and frame numbers in the frames at the reception end.
Claim 4
Dependent Claim
41 words
A method according to claim 1 or 2, further comprising: transmitting frames in accordance with CCITT recommendation V.110 in the parallel traffic channels; and carrying the channel numbering and the potential frame numbering in redundant status bits of the V.110 frames.
Claim 5
Dependent Claim
27 words
A method according to claim 3, comprising: using one or more of status bits S1, S4 and S6 for the channel numbering of the parallel traffic channels.
Claim 6
Dependent Claim
25 words
A method according to claim 4, further comprising using one of the X status bits for the frame numbering within each of the traffic channels.
Claim 7
Dependent Claim
29 words
A method according to claim 4, further comprising using S3 status bit and one of the X status bits for the frame numbering within each of the traffic channels.
Claim 8
Dependent Claim
175 words
