Optimized page matching

1. A method for optimized page matching, comprising:

reading a portion of a sub-slot of a paging channel;

extracting a page message from the portion of the sub-slot;

performing a page matching procedure prior to the end of the sub-slot from which the page message is extracted; and

initiating a procedure to return to sleep mode if the page matching procedure indicates that the page message is an empty general page message.

2. The method of claim 1 , further comprising initiating a procedure to switch to active mode if the page matching procedure indicates that the page message is a direct page message.

3. The method of claim 1 , wherein the method is performed by a wireless communication device.

4. The method of claim 3 , further comprising initiating a procedure to return to sleep mode if the page message is neither an empty general page message nor a direct page message and the wireless communication device has been awake for eight consecutive sub-slots.

5. The method of claim 3 , further comprising reading a portion of a next sub-slot if the page message is neither an empty general page message nor a direct page message and the wireless communication device has not been awake for eight consecutive sub-slots.

6. The method of claim 3 , wherein the method increases sleep time of the wireless communication device.

7. The method of claim 3 , wherein the wireless communication device is operating in an optimal network that transmits one of an empty general page message and a direct page message during a first sub-slot of a slot.

8. The method of claim 3 , wherein the wireless communication device is operating in a non-optimal network that transmits one of an empty general page message and a direct page message during a sub-slot subsequent to a first sub-slot of a slot.

9. The method of claim 1 , wherein the method reduces awake time of one subscription in slotted mode, thereby reducing conflicts between dual subscriptions wake-up in dual SIM dual standby devices.

10. The method of claim 1 , wherein the page matching procedure comprises quick page matching.

11. The method of claim 1 , wherein the page message is received via a paging channel.

12. The method of claim 1 , wherein the page message is not received via a quick paging channel.

13. A wireless device configured for optimized page matching, comprising:

a processor;

memory in electronic communication with the processor;

instructions stored in the memory, the instructions being executable by the processor to:

read a portion of a sub-slot of a paging channel;

extract a page message from the portion of the sub-slot;

perform a page matching procedure prior to the end of the sub-slot from which the page message is extracted; and

initiate a procedure to switch to active mode if the page matching procedure indicates that the page message is a direct page message.

14. The wireless device of claim 13 , wherein the instructions are further executable to initiate a procedure to return to sleep mode if the page matching procedure indicates that the page message is an empty general page message.

15. The wireless device of claim 13 , wherein the wireless device is a wireless communication device.

16. The wireless device of claim 15 , wherein the instructions are further executable to initiate a procedure to return to sleep mode if the page message is neither an empty general page message nor a direct page message and the wireless communication device has been awake for eight consecutive sub-slots.

17. The wireless device of claim 15 , wherein the instructions are further executable to read a portion of a next sub-slot if the page message is neither an empty general page message nor a direct page message and the wireless communication device has not been awake for eight consecutive sub-slots.

18. The wireless device of claim 15 , wherein the wireless device has an increased sleep time.

19. The wireless device of claim 15 , wherein the wireless device is operating in an optimal network that transmits one of an empty general page message and a direct page message during a first sub-slot of a slot.

20. The wireless device of claim 15 , wherein the wireless device is operating in a non-optimal network that transmits one of an empty general page message and a direct page message during a sub-slot subsequent to a first sub-slot of a slot.

21. The wireless device of claim 13 , wherein the instructions when executed by the processor reduce awake time of one subscription in slotted mode, thereby reducing conflicts between dual subscriptions wake-up in dual SIM dual standby devices.

22. The wireless device of claim 13 , wherein the page matching procedure comprises quick page matching.

23. The wireless device of claim 13 , wherein the page message is received via a paging channel.

24. The wireless device of claim 13 , wherein the page message is not received via a quick paging channel.

25. A computer-program product for optimized page matching, the computer-program product comprising a non-transitory computer-readable medium having instructions thereon, the instructions comprising:

code for causing a wireless device to read a portion of a sub-slot of a paging channel;

code for causing the wireless device to extract a page message from the portion of the sub-slot;

code for causing the wireless device to perform a page matching procedure prior to the end of the sub-slot from which the page message is extracted; and

code for causing the wireless device to initiate a procedure to return to sleep mode if the page matching procedure indicates that the page message is an empty general page message.

26. The computer-program product of claim 25 , further comprising code executable to initiate a procedure to switch to active mode if the page matching procedure indicates that the page message is a direct page message.

27. A wireless device configured for optimized page matching, comprising:

a processor;

memory in electronic communication with the processor;

instructions stored in the memory, the instructions being executable by the processor to:

read a portion of a sub-slot of a paging channel;

extract a page message from the portion of the sub-slot, wherein the page message is received via a paging channel; and

perform a page matching procedure prior to the end of the sub-slot from which the page message is extracted.

28. A wireless device configured for optimized page matching, comprising:

a processor;

memory in electronic communication with the processor;

instructions stored in the memory, the instructions being executable by the processor to:

read a portion of a sub-slot of a paging channel;

extract a page message from the portion of the sub-slot, wherein the page message is not received via a quick paging channel; and

perform a page matching procedure prior to the end of the sub-slot from which the page message is extracted.

29. A wireless device configured for optimized page matching, comprising:

means for reading a portion of a sub-slot of a paging channel;

means for extracting a page message from the portion of the sub-slot;

means for performing a page matching procedure prior to the end of the sub-slot from which the page message is extracted; and

means for initiating a procedure to return to sleep mode if the page matching procedure indicates that the page message is an empty general page message.

30. The wireless device of claim 29 , wherein the empty general page message indicates that no more direct page messages will be sent to the wireless device for a slot cycle.
