Abstract

A method for arranging a packet radio service in a wireless telecommunication system comprising at least one mobile station. The method comprises activating in the mobile station at least one packet data context for packet-switched data transmission of an application in the mobile station. In the mobile station, a busy condition is automatically set for the packet data context for suspension situations. When the packet data context in the mobile station is requested to be suspended, the packet data context is prevented from being suspended in response to the packet data context suspension request being received from outside the application.

Claims

1. A method for arranging a packet radio service in a wireless telecommunication system comprising at least one mobile station, the method comprising:

activating in the mobile station at least one packet data context for packet-switched data transmission of an application in the mobile station,

setting a busy condition automatically for the packet data context in the mobile station for suspension situations,

requesting suspension of the packet data context, and

preventing in the mobile station the packet data context from being suspended in response to the packet data context suspension request being received from outside the application.

2. The method of claim 1, wherein the busy condition is set automatically when activating the packet data context.

3. The method of claim 1, wherein the busy condition is set automatically only for certain predetermined applications.

4. The method of claim 1, wherein the busy condition is set at the request of the application utilizing the packet data context.

5. The method of claim 1, wherein a synchronization session is arranged using the packet data context,

the stage of synchronization is checked in response to the request to suspend the synchronization session or the packet data context, and

the synchronization session and the packet data context are prevented from being suspended in response to the synchronization session having reached a predetermined threshold stage.

6. The method of claim 1, wherein the request to suspend the packet data context is initiated by a user.

7. The method of claim 1, wherein the request to suspend the packet data context is caused by an incoming circuit-switched call to the mobile station.

8. The method of claim 7, wherein the circuit-switched call is diverted to another number.

9. The method of claim 7, wherein the circuit-switched call is diverted to a voice message system.

10. The method of claim 7, wherein caller identification is determined, and

the call is rejected.

11. The method of claim 10, wherein the circuit-switched call is diverted to another number.

12. The method of claim 10, wherein the circuit-switched call is diverted to a voice message system.

13. A mobile station comprising:

means for activating at least one packet data context for packet-switched data transmission of an application in the mobile station,

means for setting a busy condition automatically for the packet data context in the mobile station for suspension situations,

means for receiving a request to suspend the packet data context, and

means for preventing the packet data context from being suspended in response to such a busy condition being set.

14. The mobile station of claim 13, wherein the mobile station further comprises

means for setting a busy condition at the request of the application utilizing the packet data context.

15. The mobile station of claim 13, wherein the mobile station further comprises

means for receiving a setup message of an incoming call,

means for determining caller identification and presenting it to a user, and

means for rejecting the call in response to the busy condition being set.

16. The mobile station of claim 13, wherein the mobile station further comprises

means for arranging a synchronization session, using the packet data context,

means for checking the stage of synchronization in response to the request to suspend the synchronization session or the packet data context, and

means for preventing the synchronization session and the packet data context from being suspended in response to the synchronization session having reached a predetermined threshold stage.
