Method for operating a radiocommunication system
A radiocommunication system has a downward link radio channel associated with each upward link radio channel, respectively. A subscriber station receives data from a radio station on a network side to the downward link radio channel, with no logic liaison being established between the subscriber station and the radio station on the network side. A message is sent by the subscriber station on the upward link radio channel associated with the downward link radio channel. Said message is emitted by the radio station on the network side via the downward link radio station.

9 . A method for operating a radio communication system, comprising:
assigning each radio channel in an upward direction to a corresponding radio channel in a downward direction;
receiving data at a subscriber station which was transmitted from a network-side radio station via a radio channel in the downward direction, the data being received without a logical connection being set up between the subscriber station and the network-side radio station;
transmitting a message from the subscriber station via a radio channel in the upward direction which is assigned to the radio channel via which the data was received, the message commenting on the data received ; and
retransmitting the message from the network-side radio station via the radio channel in the downward direction that was used to transmit the data, the message being retransmitted with no involvement by a core network of the radio communication system.
10 . The method in accordance with claim 9 , wherein the subscriber station identifies the radio channel in the upward direction which is assigned to the radio channel via which the data was received, by:
extracting parameters associated with the radio channel in the upward direction from a signaling message received from the network-side radio station, or
determining the parameters associated with the radio channel in the upward direction from parameters associated with the radio channel in the downward direction.
11 . The method in accordance with claim 9 , wherein the message is retransmitted via the radio channel in the downward direction, with a lower priority than transmission of data via the radio channel in the downward direction.
12 . The method in accordance with claim 9 , wherein when the message is retransmitted from the network-side radio station, the message is multiplexed with the data and transmitted via the radio channel in the downward direction.
13 . The method in accordance with claim 12 , wherein
the message has an identifier which indicates that the message should not be transmitted by the network-side radio station towards the core network of the radio communication system.
14 . The method in accordance with claim 9 , wherein the message is transmitted from the subscriber station to the network-side radio station without a logical connection being set up between the subscriber station and the network-side radio station.
15 . The method in accordance with claim 9 , wherein a connection is set up between the subscriber station and the network-side radio station for purposes of transmitting packet data, via which the message is transmitted.
16 . The method in accordance with claim 9 , wherein there is a restriction on the extent to which messages can be transmitted by a subscriber station and retransmitted by the network-side radio station.
17 . The method in accordance with claim 10 , wherein the message is retransmitted via the radio channel in the downward direction, with a lower priority than transmission of data via the radio channel in the downward direction.
18 . The method in accordance with claim 17 , wherein when the message is retransmitted from the network-side radio station, the message is multiplexed with the data and transmitted via the radio channel in the downward direction.
19 . The method in accordance with claim 18 , wherein
the message has an identifier which indicates that the message should not be transmitted by the network-side radio station towards the core network of the radio communication system.
20 . The method in accordance with claim 19 , wherein the message is transmitted from the subscriber station to the network-side radio station without a logical connection being set up between the subscriber station and the network-side radio station.
21 . The method in accordance with claim 20 , wherein there is a restriction on the extent to which messages can be transmitted by a subscriber station and retransmitted by the network-side radio station.
22 . The method in accordance with claim 19 , wherein a connection is set up between the subscriber station and the network-side radio station for purposes of transmitting packet data, via which the message is transmitted.
23 . The method in accordance with claim 22 , wherein there is a restriction on the extent to which messages can be transmitted by a subscriber station and retransmitted by the network-side radio station.
