Abstract

A method of limiting the quality of service of data transmission in a wireless telecommunications system, in which the quality of service of data transmission is defined by means of quality of service parameters. Subscriber-specific maximum values are defined for the quality of service parameters and stored in a database comprising subscriber data. When the terminal requests connection establishment defined with quality of service parameters, the subscriber-specific maximum values are checked in the database and they are compared with the quality of service parameters requested by the terminal. Depending on whether the quality of service parameters requested by the terminal are within the limits defined by the maximum values of the parameters or whether at least one quality of service parameter requested by the terminal exceeds the maximum value defined for said parameter, either a connection is established or connection establishment is rejected.

Claims

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 the 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 the quality of service parameter in the database comprising the subscriber data;

comparing the at least one quality of service parameter requested by the terminal 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 in response to the fact that at least one of the quality of service parameters requested by the terminal exceeds the maximum value defined for the quality of service parameter.

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.

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.

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.

5. A method according claim 1, wherein the 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, wherein at least one subscriber-specific maximum value of the quality of service parameter is defined on the basis of another parameter.

7. A method according to claim 1, wherein the 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, wherein the quality of service of data transmission is defined by means of quality of service parameters in the system;

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

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

the terminal is configured to request connection establishment defined with at least one quality of service parameter;

the subscriber-specific maximum value of the quality of service parameter is configured to be checked in the database comprising the subscriber data;

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

connection establishment with lower values of the quality of service parameter is configured to be offered to the terminal to be accepted in response to the fact that at least one of the quality of service parameters requested by the terminal exceeds the maximum value defined for the quality of service parameter.

9. A telecommunications system according claim 8, wherein

the system comprises a wireless circuit-switched data transmission system.

10. A telecommunications system according to claim 8, wherein

the system comprises a wireless circuit-switched data transmission system.

11. A telecommunications system according to claim 8, wherein the system comprises an intelligent network-based data transmission 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

at least one subscriber-specific maximum value of the quality of service parameter is configured to be defined by means of another parameter.

14. A telecommunications system according to claim 8, wherein at least one subscriber-specific maximum value of the quality of service parameter is arranged to be defined by the service provider.

15. 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 mobile 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 the 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 the quality of service parameter;

comparing the at least one quality of service parameter requested by the terminal 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 in response to the fact that at least one of the quality of service parameters requested by the terminal exceeds the maximum value defined for the quality of service parameter.

16. A wireless telecommunications system which comprises

at least one terminal and a mobile network which comprises a database for storing subscriber data, wherein the quality of service of data transmission is defined by means of quality of service parameters in the system;

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

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

the terminal is configured to request connection establishment defined with at least one quality of service parameter;

the subscriber-specific maximum value of the quality of service parameter is configured to be checked;

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

connection establishment with lower values of the quality of service parameter is configured to be offered to the terminal to be accepted in response to the fact that at least one of the quality of service parameters requested by the terminal exceeds the maximum value defined for the quality of service parameter.
