Abstract

A method for employing an indication of stored temporary information during redirection may include receiving a temporary stored information indicator from a mobile terminal indicating that the mobile terminal stores a system information container comprising temporary information, and determining whether to replace the temporary information with non-temporary information based on reception of the temporary stored information indicator. Alternatively, the method may include receiving a system information container for at least one target cell, storing the system information container, and generating a temporary stored information indicator at a mobile terminal indicating that the mobile terminal stores the system information container comprising temporary information. Corresponding apparatuses and computer program products are also provided.

Claims

1. A method comprising:

receiving a system information container comprising temporary information for at least one target cell, as part of a connection release message during redirection, wherein the temporary information comprises a temporary neighbor cell list that is a subset of a complete neighbor cell list provided by a network element such that the temporary neighbor cell list is reduced relative to the complete neighbor cell list provided by the network element;

generating a temporary stored information indicator at a mobile terminal indicating that the mobile terminal stores the system information container;

receiving, following generation of the temporary stored information indicator, non-temporary information comprising the complete neighbor cell list; and

causing a replacement of the temporary information with the non-temporary information once the connection requirement to the target cell is met.

2. The method of claim 1, wherein receiving the system information container comprises receiving an indication of support for the temporary stored information indicator.

3. The method of claim 2, wherein the indication of support comprises a new information element or an existing information element.

4. The method of claim 2, wherein generating the temporary stored information indicator is performed responsive to receipt of the indication of support.

5. The method of claim 1, further comprising causing storage of the system information container.

6. The method of claim 1, wherein the temporary stored information indicator indicates that the mobile terminal stores the system information container and that a condition requirement with respect to connection to a target cell is met.

7. The method of claim 1, wherein the temporary stored information indicator comprises a new information element or an existing information element.

8. An apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:

receive a system information container comprising temporary information for at least one target cell, as part of a connection release message during redirection, wherein the temporary information comprises a temporary neighbor cell list that is a subset of a complete neighbor cell list provided by a network element such that the temporary neighbor cell list is reduced relative to the complete neighbor cell list provided by the network element;

generate a temporary stored information indicator at a mobile terminal indicating that the mobile terminal stores the system information container;

receive, following generation of the temporary stored information indicator, non-temporary information comprising the complete neighbor cell list; and

cause a replacement of the temporary information with the non-temporary information once the connection requirement to the target cell is met.

9. The apparatus of claim 8, wherein the at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus to receive the system information container by receiving an indication of support for the temporary stored information indicator.

10. The apparatus of claim 9, wherein the indication of support comprises a new information element or an existing information element.

11. The apparatus of claim 9, wherein the at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus to generate the temporary stored information indicator responsive to receipt of the indication of support.

12. The apparatus of claim 8, wherein the at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus to cause storage of the system information container.

13. The apparatus of claim 8, wherein the temporary stored information indicator indicates that the mobile terminal stores the system information container and that a condition requirement with respect to connection to a target cell is met.

14. The apparatus of claim 8, wherein the temporary stored information indicator comprises a new information element or an existing information element.

15. A computer program product comprising at least one non-transitory computer-readable storage medium bearing computer program code embodied therein for use with a computer, the computer program code comprising code for:

receiving a system information container comprising temporary information for at least one target cell, as part of a connection release message during redirection, wherein the temporary information comprises a temporary neighbor cell list that is a subset of a complete neighbor cell list provided by a network element such that the temporary neighbor cell list is reduced relative to the complete neighbor cell list provided by the network element;

generating a temporary stored information indicator at a mobile terminal indicating that the mobile terminal stores the system information container;

receiving, following generation of the temporary stored information indicator, non-temporary information comprising the complete neighbor cell list; and

causing a replacement of the temporary information with the non-temporary information once the connection requirement to the target cell is met.

16. The computer program product of claim 15, wherein code for receiving the system information container includes code for receiving an indication of support for the temporary stored information indicator.

17. The computer program product of claim 16, wherein the indication of support comprises a new information element or an existing information element.

18. The computer program product of claim 16, wherein the code for generating the temporary stored information indicator comprises code for generating the temporary stored information indicator responsive to receipt of the indication of support.

19. The computer program product of claim 15, wherein the computer program code further comprises code for causing storage of the system information container.

20. The computer program product of claim 15, wherein the temporary stored information indicator indicates that the mobile terminal stores the system information container and that a condition requirement with respect to connection to a target cell is met.
