Method, device, system and software product for providing system information to enable packet switched handover

1. A method comprising:

providing an indication in a source to target transparent container from a source radio network controller indicating whether the source radio network controller requests system information from a handover target, wherein no request is made if the source radio network controller is a controlling radio network controller that implements Radio Access Network Information Management procedure with Network Assisted Cell Change (RIM/NACC);

receiving the system information in a target to source transparent container from the handover target when the indication indicates that the source radio network controller requests the system information; and

sending to a user equipment at least a part of the system information that is received in the target to source transparent container.

2. The method of claim 1 , wherein the system information includes information required by a mobile station for a packet switched handover.

3. The method of claim 2 , wherein the packet switched handover is a handover to a different radio access technology.

4. The method of claim 2 , wherein the packet switched handover is a handover to a different base station subsystem.

5. The method of claim 1 , wherein the target to source transparent container is sent from a target radio network controller with a relocation command.

6. The method of claim 1 , wherein the target to source transparent container is received at the source radio network controller.

7. The method of claim 1 , wherein providing the indication is accomplished by including an indicator or alternatively by omitting an indicator.

8. The method of claim 1 , wherein the indication indicates that the source radio network controller requests to not receive the system information from the handover target, if the source radio network controller is a controlling radio network controller that implements a radio access network information management procedure with network assisted cell change.

9. A computer program product comprising a non-transitory tangible computer readable storage structure having computer program code embedded therein for execution by a processor; the computer program product including instructions for:

providing an indication in a source to target transparent container from a source radio network controller indicating whether the source radio network controller requests system information from a handover target, wherein no request is made if the source radio network controller is a controlling radio network controller that implements Radio Access Network Information Management procedure with Network Assisted Cell Change (RIM/NACC);

receiving the system information in a target to source transparent container from the handover target when the indication indicates that the source radio network controller requests the system information; and

sending to a user equipment at least a part of the system information that is received in the target to source transparent container.

10. The computer program product of claim 9 , wherein the system information includes information required by a mobile station for a packet switched handover.

11. The computer program product of claim 9 , wherein the target to source transparent container is sent from a target radio network controller with a relocation command.

12. An apparatus comprising:

means for providing an indication in a source to target container from a source radio network controller indicating whether the source radio network controller requests system information from a handover target, wherein no request is made if the source radio network controller is a controlling radio network controller that implements Radio Access Network Information Management procedure with Network Assisted Cell Change (RIM/NACC);

means for receiving the system information in a target to source transparent container from the handover target when the indication indicates that the source radio network controller requests the system information; and

means for sending to a user equipment at least a part of the system information that is received in the target to source transparent container.

13. The apparatus of claim 12 , wherein the system information includes information required by a mobile station for a packet switched handover.

14. The apparatus of claim 12 , wherein the target to source transparent container is sent from a target radio network controller with a relocation command.

15. A network element comprising:

at least one transmitting module, wherein at least one of the at least one transmitting module is configured to provide an indication in a source to target transparent container from a source radio network controller indicating whether the source radio network controller requests system information from a handover target, wherein no request is made if the source radio network controller is a controlling radio network controller that implements Radio Access Network Information Management procedure with Network Assisted Cell Change (RIM/NACC); and

a receiving module configured to receive the system information in a target to source transparent container from the handover target when the indication indicates that the source radio network controller requests the system information,

wherein at least one of the at least one transmitting module is configured to send to a user equipment at least a part of the system information that is received in the target to source transparent container.

16. The network element of claim 15 , wherein the system information includes information required by a mobile station for a packet switched handover.

17. The network element of claim 15 , wherein the target to source transparent container from a target radio network controller conveys a relocation command.

18. A system comprising:

a source radio network controller configured to provide an indication in a source to target transparent container indicating whether the source radio network controller requests system information from a handover target, wherein no request is made if the source radio network controller is a controlling radio network controller that implements Radio Access Network Information Management procedure with Network Assisted Cell Change (RIM/NACC); and

a target radio network controller configured to provide the system information in a target to source transparent container to the source radio network controller when the indication indicates that the source radio network controller requests the system information,

wherein the source radio network controller is further configured to send to a user equipment at least a part of the system information that is received in the target to source transparent container.

19. The system of claim 18 , wherein the system information includes information required by a mobile station for a packet switched handover.
