Patent ID: 7023823

Claim:
A wireless network comprising a radio network controller ( 1 ) and a plurality of assigned terminals ( 2 to 9 ) for exchanging useful data and control data, which terminals respectively have a buffer for buffering data packets to be transmitted to the radio network controller ( 1 ) via a contention channel and a measuring device for measuring the occupancy level of at least one buffer, characterized in that a terminal ( 2 to 9 ), when an occupancy level of a buffer or various buffers is exceeded, is provided for sending a signaling sequence at a start time predefined by the radio network controller ( 1 ), in that the radio network controller ( 1 ) includes a device for correlating a signaling sequence sent by a terminal ( 2 to 9 ) and for detecting the pulse developed from a received and correlated signaling sequence, and in that the radio network controller ( 1 ), after detecting a signaling sequence assigned to a terminal ( 2 to 9 ), is arranged for sending an indication to the terminal ( 2 to 9 ) to further transmit the data packets over a channel assigned only to the terminal.
