Abstract:
1. A network system comprising a mobile telecommunication network, in which data is transmitted in form of transmission frames, comprising a network control unit for controlling communication in the network; and a terminal for receiving and transmitting data from/to said network control unit; wherein said network control unit is adapted to receive a request for changing a data rate from a first user data rate to a second user data rate, said transmission frames always contain fill data actually not used, and said network control unit is adapted to add/delete fill data to/from a transmission frame corresponding to the requested change of said data rate for transmitting data to said terminal at said second data rate; wherein said terminal is adapted to detect the change in the amount of fill data and to change the user data rate for transmitting data to said network control unit according to the detected change by adding/deleting fill data in transmission frames corresponding to the requested change of user data rate, and wherein said network control unit is adapted to indicate presence of fill data in a predetermined part of said transmission frame and to indicate an amount of fill data within the fill data of said transmission frame.
