  • Method and a system for reserving transmission capacity
    Patent number: 6831894
    Abstract: 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).
