Wireless network with capacity measurement

A radio network controller (1) in a wireless network for exchanging useful data and control data comprising a plurality of assigned terminals (2 to 9), characterized

• in that the radio network controller (1) includes a device for correlating a signaling sequence transmitted by a terminal (2 to 9) and for detecting the peak evolved from a received and correlated signaling sequence,
• in that a signaling sequence transmitted at a certain time by a terminal (2 to 9) indicates that the occupancy level of the buffer or of various buffers in the respective terminal (2 to 9) has been exceeded and
• in that the radio network controller (1), after detecting a signaling sequence assigned to a terminal (2 to 9), is provided for sending an indication to the terminal (2 to 9) for the further transmission of the data packets over a channel exclusively assigned to the terminal (2 to 9).

A terminal (2 to 9) in a wireless network for exchanging useful data and control data with at least one radio network controller (1) and further terminals, which terminal includes at least one buffer for buffering data packets to be transmitted to the radio network controller (1) over a contention channel and a measuring device for measuring the occupancy level of at least one buffer, characterized

• in that the 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) and
• in that the terminal (2 to 9) is provided for receiving an indication from the radio network controller (1) which detects the signaling sequence that a channel exclusively assigned to the terminal (2 to 9) can be used for the further transmission of the data packets.

A method of exchanging useful data and control data in a wireless network with a radio network controller (1) and a plurality of assigned terminals (2 to 9) which respectively have at least one buffer for buffering data packets to be transmitted to the radio network controller (1) over a contention channel and a measuring device for measuring the occupancy level of at least one buffer, characterized

• in that a signaling sequence is transmitted by a terminal (2 to 9) at a start time respectively predefined by the radio network controller (1) after an occupancy level of one or more buffers is exceeded,
• in that a signaling sequence transmitted and received by a terminal (2 to 9) is correlated in the radio network controller (1) and the ensuing peak is detected and
• in that an indication for the terminal (2 to 9) to use a channel exclusively assigned to the terminal (2 to 9) for the further transmission of the data packets is transmitted by the radio network controller (1) after the detection of a signaling sequence assigned to a terminal (2 to 9).
