<p>The object of the invention is a method for reserving transmission capacity required by the acknowledgement and/or response messages (33) in a bi-directional transmission system, where a message (16) is transmitted from a first unit (12) to a second unit (13), the second unit (13) receives the message (16) transmitted by the first unit (12), and the second unit (13) transmits an acknowledgement and/or response message (33) as a response to the received message (16) so that the reservation of the transmission capacity required by the acknowledgement and/or response message (33) is made substantially in connection with the transmission of the message (16) transmitted from the first unit (12) to the second unit (13). An object of the invention is also a system for reserving transmission capacity required by the acknowledgement and/or response messages (16) in a bi-directional transmission system, whereby the transmission system comprises at least a first unit (12) having means for transmitting and receiving a message (16), and a second unit (13) for receiving the message (16) and for transmitting acknowledgement and/or response messages (33), and the first unit (12) and/or the second unit (13) have means for making the reservation of transmission capacity required by the acknowledgement and/or response message (16) substantially in connection with the transmission of a message (16) transmitted from the first unit (12) to the second unit (13). <IMAGE></p> |
