Abstract

Exemplary embodiments are directed to operation of a device supporting multiple SIMs. A method may include detecting a paging collision scenario between a first subscription and at least a second subscription. The method may further include modifying a page reading operation of at least one of the first subscription and the at least a second subscription to avoid a paging collision between the first subscription and the at least a second subscription. Other aspects, embodiments, and features are also claimed and described in the application.

First claim

What is claimed is:

1. A method, comprising:
determining whether a first subscription and a second subscription are on separate cells;
determining whether the separate cells are within a common location;
detecting a paging collision scenario between the first subscription and the second subscription; and
modifying a page reading operation of at least one of the first subscription or the second subscription to avoid a paging collision between the first subscription and the second subscription, the modifying comprising:
reading alternative subscription page blocks from a determined common control channel configuration group if the determined common control channel configuration group for the first subscription is the same as the determined common control channel configuration group for the second subscription and a determined paging group for the first subscription is not the same as a determined paging group for the second subscription, and the separate cells are within the common location; and
sharing paging information from the first subscription or the second subscription if the determined common control channel configuration group for the first subscription is the same as the determined common control channel configuration group for the second subscription and the determined paging group for the first subscription is the same as the determined paging group for the second subscription, and the separate cells are within the common location.

2. The method of claim 1 , further comprising:
determining that the common control channel configuration group for the first subscription is the same as the determined common control channel configuration group for the second subscription: and
determining that the paging group for the first subscription is not the same as the determined paging group for the second subscription.

3. The method of claim 1 , wherein detecting a paging collision comprises detecting a paging collision between the first subscription and the second subscription associated with the single cell.

4. The method of claim 1 , wherein detecting a paging collision comprises detecting a paging collision between the first subscription and the second subscription having different subscription identities.

5. The method of claim 1 , wherein detecting a paging collision comprises detecting a paging collision between the first subscription and the second subscription having adjacent page blocks.

6. A device, comprising:
means for determining whether a first subscription and a second subscription are on separate cells;
means for determining whether the separate cells are within a common location;
means for detecting a potential paging collision between the first subscription and the second subscription; and
means for modifying a page reading operation of at least one of the first subscription or the second subscription to avoid a paging collision between the first subscription and the second subscription, the means for modifying comprising:
means for reading alternative subscription page blocks from a determined common control channel configuration group if the determined common control channel configuration group for the first subscription is the same as the determined common control channel configuration group for the second subscription and a determined paging group for the first subscription is not the same as a determined paging group for the second subscription, and the separate cells are within the common location; and
means for sharing paging information from the first subscription or the second subscription if the determined common control channel configuration group for the first subscription is the same as the determined common control channel configuration group for the second subscription and the determined paging group for the first subscription is the same as the determined paging group for the second subscription, and the separate cells are within the common location.

7. The device of claim 6 , further comprising:
means for determining that the common control channel configuration group for the first subscription is the same as the determined common control channel configuration group for the second subscription: and
means for determining that the paging group for the first subscription is not the same as the determined paging group for the second subscription.

8. The device of claim 6 , wherein the means for detecting comprises means for detecting a paging collision between the first subscription and the second subscription associated with the single cell.

9. The device of claim 6 , wherein the means for detecting comprises means for detecting the potential paging collision between the first subscription and the second subscription having different subscription identities.

10. The device of claim 6 , wherein the means for detecting comprises means for detecting the potential paging collision between the first subscription and the second subscription having adjacent page blocks.

11. A non-transitory computer-readable medium including computer-executable instructions, which when executed on a computer, perform the acts comprising:
determining whether a first subscription and a second subscription are on separate cells;
determining whether the separate cells are within a common location;
detecting a potential paging collision between the first subscription and the second subscription; and
modifying a page reading operation of at least one of the first subscription or the second subscription to avoid a paging collision between the first subscription and the second subscription, the modifying comprising:
reading alternative subscription page blocks from a determined common control channel configuration group if the determined common control channel configuration group for the first subscription is the same as the determined common control channel configuration group for the second subscription and a determined paging group for the first subscription is not the same as a determined paging group for the second subscription, and the separate cells are within the common location; and
sharing paging information from the first subscription or the second subscription if the determined common control channel configuration group for the first subscription is the same as the determined common control channel configuration group for the second subscription and the determined paging group for the first subscription is the same as the determined paging group for the second subscription, and the separate cells are within the common location.

12. The non-transitory computer-readable medium of claim 11 , wherein the instructions further perform the acts comprising:
determining that the common control channel configuration group for the first subscription is the same as the determined common control channel configuration group for the second subscription: and
determining that the paging group for the first subscription is not the same as the determined paging group for the second subscription.

13. The non-transitory computer-readable medium of claim 11 , wherein detecting comprises detecting a paging collision between the first subscription and the second subscription associated with the single cell.

14. The non-transitory computer-readable medium of claim 11 , wherein detecting comprises detecting the potential paging collision between the first subscription and the second subscription having adjacent page blocks.

15. A method, comprising:
determining whether a first subscription and a second subscription are on separate cells;
determining whether the separate cells are within a common location;
