Claims

1. A method for transferring a data flow by creating a connection on a packet radio service of a telecommunication system, said connection constituting a packet data channel, wherein the data flow comprises at least one active data transfer period, characterised in that information is transferred between the mobile station and the network on whether after the active data transfer period a passive period starts or whether a connection release is allowed.

2. A method according to claim 1, characterized in that said information is transferred during the active data transfer period.

3. A method according to claim 1, characterised in that said information is transferred on the packet data channel.

4. A method according to claim 3, characterised in that the data flow is arranged to consist of data blocks, and said information is transferred in a header of a data block.

5. A method according to claim 4, characterised in that the radio service is GPRS and the header is a MAC header of a RLC block.

6. A method according to claim 1, characterised in that it comprises the step of creating a control connection between the mobile station and the network, said control connection being separate from said packet data channel and constituting a control channel, wherein said information is transferred on the control channel.

7. A method according to any of claims 1-6, characterised in that when the same packet data channel is allocated for more than one connection of delay sensitive data, all such connections having a passive period, and when a first connection changes to an active transfer period, a second connection is reallocated to another packet data channel.

8. A method according to claim 7, characterised in that said second connection is reallocated to another packet data channel essentially immediately after said first connection has become active.

9. A method according to claim 7, characterised in that said second connection is reallocated to another packet data channel, when said second connection becomes active.

10. A method according to any of the previous claims, characterised in that when a passive data transfer period follows an active data transfer period, the network allocates a number of transmit permissions that can be allocated to other temporary block flows on the packet data channel.

11. A method according to any of the previous claims, characterised in that when allocating data transfer resources for a first direction (uplink/downlink) of packet data transfer, resources are also allocated for packet data transfer of the opposite data transfer direction.

12. A method according to claim 11, characterised in that the resource allocation in the opposite data transfer dkection is initialised with a message between the mobile station and the network.

13. A method according to any of the previous claims, characterised in that when releasing a temporary block flow in a first dkection (uplink/downlink) of packet data ttansfer, a temporary block flow in the opposite data transfer direction is maintained at least for a predetermined time.

14. A method according to any of claims 1-12, characterised in that the release of the downlink temporary block flow is initialised with a message between the mobile station and the network.

15. A method according to any of the previous claims, characterised in that the network is informed on whether the packet data to be transferred is delay sensitive.

16. A telecommunications system for transferring a data flow by creating a connection on a packet radio service, wherein the data flow comprises at least one active data transfer period, characterised in that the cellular communications system comprises means for receiving information on whether after the active data transfer period a passive period starts or whether a connection release is allowed.

17. A telecommunications system according to claim 16, characterised in that the system comprises means for allocating the same packet data channel for at least two connections of delay sensitive data, both connections comprising a passive period, and means for reallocating a second connection to another packet data channel after a first connection becomes active.

18. A mobile station for transferring a data flow by creating a connection on a packet radio service to a cellular telecommunications system, wherein the data flow comprises at least one active data transfer period, characterised in that the mobile station comprises means for transmitting information on whether after the active data transfer period a passive period starts or whether a connection release is allowed.

19. A mobile station according to claim 18, characterised in that the means for transmitting the information comprises means for transmitting the information in the MAC header of a RLC block in GPRS.

20. A method for transferring a data flow by creating a connection on a packet radio service of a telecommunication system, wherein the data flow comprises at least one active data transfer period, characterised in that after an active data transfer period the connection is maintained for a predetermined time, whereafter the connection is released.
