Methods and apparatuses for optimization of multiple subscription device performance

1. A method of tune away in wireless communications, comprising:

receiving a master information block (MIB) from a first subscription network entity on a first subscription in a user equipment (UE);

determining, from the MIB, system information block (SIB) scheduling information associated with the first subscription network entity;

determining, based at least in part on the SIB scheduling information, one or more dormant SIB periods during which no scheduling information related to the first subscription is sent; and

tuning away from the first subscription to a second subscription during at least one dormant SIB period of the one or more dormant SIB periods to receive paging information from one or more second subscription network entities.

2. The method of claim 1 , further comprising reading one or more paging channel (PCH) blocks on the second subscription during the at least one dormant SIB period.

3. The method of claim 1 , further comprising setting a preference for receiving one or more mobile terminated calls, on the second subscription, over existing call throughput on the first subscription.

4. The method of claim 3 , wherein setting the preference for receiving one or more mobile terminated calls over existing call throughput comprises setting a first tune away preference or a second tune away preference.

5. The method of claim 4 , wherein the first tune away preference prioritizes first subscription procedures over second subscription procedures.

6. The method of claim 4 , wherein the second tune away preference prioritizes second subscription procedures to first subscription procedures.

7. The method of claim 1 , further comprising querying a second subscription network entity for the paging information during the at least one dormant SIB period.

8. The method of claim 1 , wherein tuning away from the first subscription to the second subscription comprises tuning away one or more radio resources.

9. An apparatus for tune away in a wireless system, comprising:

means for receiving a master information block (MIB) from a first subscription network entity on a first subscription in a user equipment (UE);

means for determining, based on the MIB, system information block (SIB) scheduling information associated with the first subscription network entity;

means for determining, based at least in part on the SIB scheduling information, one or more dormant SIB periods during which no scheduling information related to the first subscription is sent; and

means for tuning away from the first subscription to a second subscription during at least one dormant SIB period of the one or more dormant SIB periods to receive paging information from one or more second subscription network entities.

10. The apparatus of claim 9 , further comprising means for reading one or more paging channel (PCH) blocks on the second subscription during the at least one dormant SIB period.

11. The apparatus of claim 9 , further comprising means for setting a preference for receiving one or more mobile terminated calls, on the second subscription, over existing call throughput on the first subscription.

12. A computer program product, comprising:

a non-transitory computer-readable medium comprising code for:

receiving a master information block (MIB) from a first subscription network entity on a first subscription in a user equipment (UE);

determining, based on the MIB, system information block (SIB) scheduling information associated with the first subscription network entity;

determining, based at least in part on the SIB scheduling information, one or more dormant SIB periods during which no scheduling information related to the first subscription is sent;and

tuning away from the first subscription to a second subscription during at least one dormant SIB period of the one or more dormant SIB periods to receive paging information from one or more second subscription network entities.

13. The computer program product of claim 12 , wherein the computer-readable medium further comprises code for reading one or more paging channel (PCH) blocks on the second subscription during the at least one dormant SIB period.

14. The computer program product of claim 12 , wherein the computer-readable medium further comprises code for setting a preference for receiving one or more mobile terminated calls, on the second subscription, over existing call throughput on the first subscription.

15. The computer program product of claim 14 , wherein setting the preference for receiving one or more mobile terminated calls over existing call throughput comprises setting a first tune away preference or a second tune away preference.

16. The computer program product of claim 15 , wherein the first tune away preference prioritizes first subscription procedures over second subscription procedures.

17. The computer program product of claim 15 , wherein the second tune away preference prioritizes second subscription procedures to first subscription procedures.

18. An apparatus for tune away in wireless communications, comprising:

at least one processor; and

a memory coupled to the at least one processor, wherein the at least one processor is configured to:

receive a master information block (MIB) from a first subscription network entity on a first subscription in a user equipment (UE);

determine, based on the MIB, system information block (SIB) scheduling information associated with the first subscription network entity;

determine, based at least in part on the SIB scheduling information, one or more dormant SIB periods during which no scheduling information related to the first subscription is sent; and

tune away from the first subscription to a second subscription during at least one dormant SIB period of the one or more dormant SIB periods to receive paging information from one or more second subscription network entities.

19. The apparatus of claim 18 , wherein the at least one processor is further configured to read one or more paging channel (PCH) blocks on the second subscription during the at least one dormant SIB period.

20. The apparatus of claim 18 , wherein the at least one processor is further configured to set a preference for receiving one or more mobile terminated calls, on the second subscription, over existing call throughput on the first subscription.

21. The apparatus of claim 20 , wherein to set the preference for receiving one or more mobile terminated calls over existing call throughput, the at least one processor is further configured to set a first tune away preference or a second tune away preference.

22. The apparatus of claim 21 , wherein the first tune away preference prioritizes first subscription procedures to second subscription procedures.

23. The apparatus of claim 21 , wherein the second tune away preference prioritizes second subscription procedures to first subscription procedures.

24. The apparatus of claim 18 , wherein the at least one processor is further configured to query a second subscription network entity for paging information during the at least one dormant SIB period.

25. The apparatus of claim 18 , wherein to tune away from the first subscription to the second subscription, the at least one processor is further configured to tune away one or more radio resources.

26. The apparatus of claim 11 , wherein the means for setting sets the preference for receiving one or more mobile terminated calls over existing call throughput at least in part by setting a first tune away preference or a second tune away preference.

27. The apparatus of claim 26 , wherein the first tune away preference prioritizes first subscription procedures over second subscription procedures.

28. The apparatus of claim 26 , wherein the second tune away preference prioritizes second subscription procedures to first subscription procedures.
