Abstract

Claims (38)

1. A method for limiting the quality of service (QoS) of data transmission in a wireless telecommunications system which comprises at least one terminal and a fixed network which comprises a database for storing subscriber data, the method comprising:

defining the quality of service of-data transmission by means of quality of service parameters;

defining a subscriber-specific maximum value for at least one quality of service parameter;

storing the subscriber-specific maximum value of said at least one quality of service parameter in the database comprising the subscriber data;

checking, in response to the request made by the terminal for connection establishment defined with at least one quality of service parameter, the subscriber-specific maximum value of said quality of service parameter such that the at least one quality of service parameter requested by the terminal is compared with the subscriber-specific maximum value of the quality of service parameter; and

offering connection establishment with lower values of the quality of service parameters to the terminal to be accepted if at least one of the quality of service parameters requested by the terminal exceeds the maximum value defined for said quality of service parameter or the resources of the system, or alternatively

establishing a connection if each quality of service parameter requested by the terminal is within the limits defined by the maximum value of said quality of service parameter and sufficient system resources are available.

2. A method according to claim 1 , wherein

the method is implemented in a packet-switched data transmission system in connection with the wireless telecommunications system, such as the GPRS system.

3. A method according to claim 1 , wherein

the method is implemented in a circuit-switched data transmission system in connection with the wireless telecommunications system, such as the HSCSD system.

4. A method according to claim 1 , wherein

the method is implemented in an intelligent network-based data transmission system in connection with the wireless telecommunications system, such as the CAMEL system.

5. A method according claim 1 , wherein

said quality of service parameters comprise at least one of the following parameters: data rate, delay, error ratio, multislot class.

6. A method according to claim 1 , further comprising

defining at least one subscriber-specific maximum value of the quality of service parameter is defined on the basis of another parameter, such as the time or location of the terminal.

7. A method according to claim 1 , wherein

a service provider defines the maximum value of at least one subscriber-specific quality of service parameter.

8. A wireless telecommunications system, which comprises at least one terminal and a fixed network which comprises a database for storing subscriber data, the quality of service of data transmission being defined by means of quality of service parameters in the system; the system comprising

means for defining a subscriber-specific maximum value for at least one quality of service parameter;

means for storing the subscriber-specific maximum value of the at least one quality of service parameter, and

means for checking the subscriber-specific maximum value of said quality of service parameter such that the at least one quality of service parameter requested by the terminal is compared with the subscriber-specific maximum value of the quality of service parameter,

whereby in response to a connection establishment request defined with at least one quality of service parameter made by the terminal, the system is arranged to

offer connection establishment with lower values of the quality of service parameters to the terminal to be accepted if at least one of the quality of service parameters exceeds the maximum value defined for said quality of service parameter or the resources of the system, or alternatively,

establish a connection if each qualify of service parameter requested by the terminal is within the limits defined by the maximum value of said quality of service parameter and sufficient system resources are available.

9. A telecommunications system according claim 8 , wherein

the system comprises a wireless packet-switched data transmission system, such as the GPRS system.

10. A telecommunications system according to claim 8 , wherein

the system comprises a wireless circuit-switched data transmission system, such as the HSCSD system.

11. A telecommunications system according to claim 8 , wherein

the system comprises an intelligent network-based data transmission system, such as the CAMEL system.

12. A telecommunications system according to claim 8 , wherein

the quality of service parameters comprise at least one of the following parameters: data rate, delay, error ratio, multislot class.

13. A telecommunications system according to claim 8 , wherein the system is arranged to

define at least one subscriber-specific maximum value of the quality of service parameter by means of another parameter, such as the time or location of the terminal.

14. A telecommunications system according to claim 8 , wherein

a service provider is arranged to define at least one subscriber-specific maximum value of the quality of service parameter.
