Abstract

The invention relates to a method for reconfiguring a cellular radio network connection comprising a network part having a connection to a mobile station through at least one radio bearer. According to the invention, a first party of the connection, i.e. the network part or the mobile station, sends a second party of the connection, i.e. the mobile station or the network part, a reconfiguration request message concerning at least one radio bearer. The second party of the connection possibly replies to this by sending the first party of the connection a reply message to the radio bearer reconfiguration request message. The radio bearer reconfiguration request message comprises at least one radio bearer identifier and, for example, bearer quality of service of the radio bearer in question. The possible reply message comprises at least one radio bearer identifier and possibly also bearer quality of service assigned to the radio bearer in question, or a cause for a failed reconfiguration of the radio bearer in question.

Claims

1. A cellular radio network comprising:

a protocol software of a network layer of a network part arranged to establish a connection to a mobile station through at least one radio bearer;

a protocol software of a network layer of the mobile station arranged to establish a connection to the network part through at least one radio bearer;

the protocol software of the network layer of the network part is further arranged to transmit to the protocol software of the network layer of the mobile station a radio bearer reconfiguration request message concerning at least one radio bearer; and

the protocol software of the network layer of the mobile station is further arranged to transmit to the protocol software of the network layer of the network part a reply message to the radio bearer recognition request message, wherein the radio bearer reconfiguration request message comprises at least one radio bearer identifier and bearer quality of service of the radio bearer in question.

3. A cellular radio network according to claim 1, wherein the bearer quality of service is indicated by at least one parameter.

4. A cellular radio network according to claim 3, wherein the parameter is selected from a group consisting of bit error rate, maximum transmission delay, transmission delay deviation, priority, security and data loss at handover.

5. A cellular radio network according to claim 3, wherein the parameter is at least one LLC sublayer parameter.

7. A cellular radio network according to claim 1, wherein the radio bearer is arranged to be used for signalling.

8. A cellular radio network according to claim 1, wherein the radio bearer is arranged to be used for communication.

2. A cellular radio network comprising:

a protocol software of a network layer of a network part arranged to establish a connection to a mobile station through at least one radio bearer;

a protocol software of a network layer of the mobile station arranged to establish a connection to the network part through at least one radio bearer;

the protocol software of the network layer of the network part is further arranged to transmit to the protocol software of the network layer of the mobile station a radio bearer reconfiguration request message concerning at least one radio bearer; and

the protocol software of the network layer of the mobile station is further arranged to transmit to the protocol software of the network layer of the network part a reply message to the radio bearer reconfiguration request message, wherein the reply message comprises at least one radio bearer identifier and a cause for a failed reconfiguration of the radio bearer in question.

6. A cellular radio network according to clam 3, wherein the parameter is at least one RLC sublayer parameter.

9. A cellular radio network comprising:

a protocol software of a network layer of a network part arranged to establish a connection to a mobile station through at least one radio bearer;

a protocol software of a network layer of the mobile station arranged to establish a connection to the network part through at least one radio bearer;

the protocol software of the network layer of the mobile station is further arranged to transmit to the protocol software of the network layer of the network part a radio bearer reconfiguration request message concerning at least one radio bearer;

the protocol software of the network layer of the network part is further arranged to transmit to the protocol software of the network layer of the mobile station a reply message to the radio bearer reconfiguration request message, wherein the radio bearer reconfiguration request message comprises at least one radio bearer identifier and bearer quality of service of the radio bearer in question.

10. A cellular radio network according to claim 9, wherein the reply message comprises at least one radio bearer identifier, and a cause for a failed reconfiguration of the radio bearer in question.

11. A cellular radio network according to claim 9, wherein the bearer quality of service is indicated by at least one parameter.

12. A cellular radio network according to claim 11, wherein the parameter is selected from a group consisting of bit error rate, maximum transmission delay, transmission delay deviation, priority, security and data loss at handover.

13. A cellular radio network according to claim 11, wherein the parameter is at least one LLC sublayer parameter.

14. A cellular radio network according to claim 11, wherein the parameter is at least one RLC sublayer parameter.

15. As cellular radio network according to claim 9, wherein the radio bearer is arranged to be used for signalling.

16. A cellular radio network according to claim 9, wherein the radio bearer is arranged to be used for communication.

17. A network part of a cellular network, the network part comprising:

protocol software of a network layer of the network part arranged to have a connection to a mobile station of the cellular network through at least one radio bearer;

the protocol software of the network layer of the network part is further arranged to transmit a radio bearer reconfiguration request to a protocol software of a network layer of the mobile station; and

the radio bearer reconfiguration request message comprises at least one radio bearer identifier and a bearer quality of service of the radio bearer in question.

18. A mobile station of a cellular network, the mobile station comprising:

protocol software of a network layer of the mobile station arranged to have a connection to a network part of the cellular network through at least one radio bearer;

the protocol software of a network layer of the mobile station is further arranged to transmit to a protocol software of a network layer of the network part a reply message to a radio bearer reconfiguration request message; and

the reply message comprises at least one radio bearer identifier and a cause for a failed reconfiguration of the radio bearer in question.
