Method for transmitting data in a radio communication network

1. A method for transmitting data in a radio communications system, comprising:

providing a common channel allocated concurrently to a plurality of subscribers for data transmission between a base station and subscriber stations of the subscribers;

taking measurements in the subscriber stations of transmission quality of the common channel for each of the subscriber stations;

transmitting the measurements to the base station so as to make the measurements available to the base station; and

transmitting from the base station a first message to a controlling radio network controller allocated to the base station when the measurements show that the transmission quality does not meet a first defined criterion, the first message containing information about the transmission quality and an identifier of at least one particular subscriber station for which the measurements indicated that the transmission quality meets a second criterion,

wherein the measurements of transmission quality are based on at least one of a transmission rate via the common channel and determining a ratio of a number of elapsed timers relative to a total number of allocated timers.

2. A method in accordance with claim 1 ,

wherein each of the subscriber stations has a serving radio network controller corresponding thereto which is responsible for configuration of the respective subscriber stations, and

wherein said method further comprises transmitting a second message from the controlling radio network controller to the serving radio network controller allocated to each of the at least one particular subscriber station.

3. A method in accordance with claim 2 ,

wherein a specified transmission rate is agreed for each subscriber, and

wherein said method further comprises checking compliance with the agreed transmission rate during said making of the measurements of the transmission quality.

4. A method in accordance with claim 3 , further comprising:

allocating timers to data units to be transmitted;

ceasing transmission of the data units after a corresponding timer has elapsed; and

checking, during the making of the measurements of the transmission quality, to determine whether a number of elapsed timers relative to a total number of allocated timers exceeds a specified threshold value.

5. A method in accordance with claim 4 , wherein the first message contains at least one of a name of each of the at least one particular subscriber station and how many of the subscriber stations for which the transmission quality was bad.

6. A method in accordance with claim 5 , wherein the second message contains the name of each of the at least one particular subscriber station.

7. A method in accordance with claim 6 ,

further comprising allocating a temporary identification being to the subscriber stations by the controlling radio network controller, and

wherein the temporary identification is used to name the subscriber stations.

8. A method in accordance with claim 7 ,

further comprising deriving, by the controlling radio network controller, a suggested solution for a change of the configuration of the subscriber stations from the first message, and

wherein the second message includes the suggested solution.

9. A method in accordance with claim 8 , wherein the suggested solution contains information on at least one of a possible transmission procedure to a different base station and allocation of a dedicated channel for a corresponding one of the at least one particular subscriber station.

10. A method in accordance with claim 2 ,

further comprising deriving, by the controlling radio network controller, a suggested solution for a change of the configuration of the subscriber stations from the first message, and

wherein the second message includes the suggested solution.

11. A method in accordance with claim 1 ,

wherein each of the subscriber stations has a serving radio network controller corresponding thereto which is responsible for configuration of the respective subscriber stations, and

wherein said method further comprises transmitting a second message from the controlling radio network controller to the serving radio network controller allocated to each of the at least one particular subscriber station.

12. A method in accordance with claim 11 ,

further comprising deriving, by the controlling radio network controller, a suggested solution for a change of the configuration of the subscriber stations from the first message, and

wherein the second message includes the suggested solution.

13. A method in accordance with claim 1 ,

wherein each of the subscriber stations has a serving radio network controller corresponding thereto which is responsible for configuration of the respective subscriber stations, and

wherein said method further comprises transmitting a second message from the controlling radio network controller to the serving radio network controller allocated to each of the at least one particular subscriber station.

14. A method in accordance with claim 13 ,

further comprising deriving, by the controlling radio network controller, a suggested solution for a change of the configuration of the subscriber stations from the first message, and

wherein the second message includes the suggested solution.

15. A radio communications system, comprising:

serving radio network controllers;

a controlling radio network controller in communication with the serving radio network controllers;

base stations in communication with the controlling radio controller;

a plurality of subscriber stations using a shared channel for exchanging data with a base station among the base stations, each subscriber station being configurable based on a message received from one of serving radio network controllers,

wherein a base station sends a first message to the controlling radio network controller when a transmission quality measured in the subscriber stations and made available to the base station of at least one of the plurality of subscriber stations exchanging data with the base station does not meet a defined criterion, the first message containing information about the transmission quality and about the at least one subscriber station, and

wherein the measurements of transmission quality are based on at least one of a transmission rate via the shared channel and determining a ratio of a number of elapsed timers relative to a total number of allocated timers.

16. A radio communications system in accordance with claim 15 , wherein the controlling radio network controller sends a second message to the one of the serving radio controllers that is able to configure the at least one subscriber stations.

17. A method for transmitting data in a radio communications system in which a plurality of subscriber stations use a shared channel for exchanging data with a base station, comprising:

measuring a transmission quality of the shared channel for each of the subscriber stations in the subscriber stations;

transmitting the measured transmission quality to the base station; and

transmitting a first message from the base station to a controlling radio network controller controlling the base station when transmission quality based on one of a transmission rate and a ratio of a number of elapsed timers relative to a total number of allocated timers of at least one of the subscriber stations is inadequate, the first message containing information about the measured transmission quality of the at least one subscriber station with inadequate transmission quality.
