Abstract

A computer-implemented method performed by a UE is provided. The computer-implemented method includes generating, with a first chipset, a first set of geo-fence rules; generating, with the first chipset, a second set of geo-fence rules, which are a simplified subset of the first set of geo-fence rules; transmitting the second set of geo-fence rules to a second chipset; powering down the first chipset; detecting if at least one of the second set of geo-fence rules has been broken; and if at least one of the second set of geo-fence rules is broken, powering up the first chipset to determine if the at least one broken second rule is indicative of breaking at least one rule of the first set of geo-fence rules.

First claim

What is claimed is:

1. A method performed by a user equipment (UE), the method comprising:
generating, with a first chipset, a first set of geo-fence rules and a second set of geo-fence rules, which are a simplified subset of the first set of geo-fence rules;
transmitting the second set of geo-fence rules to a second chipset;
powering down the first chipset;
detecting if at least one of the second set of geo-fence rules has been broken; and
if at least one least one of the second set of geo-fence rules is broken, powering up the first chipset to determine if the at least one broken second rule is indicative of breaking at least one rule of the first set of geo-fence rules.

2. The method according to claim 1 , further comprising, if at least one of the second set of geo-fence rules is broken and not indicative of breaking at least one of the first set of geo-fence rules, generating, with the first chipset, another second set of geo-fence rules which are a simplified subset of the first set of geo-fence rules, and transmitting the another second set of geo-fence rules to the second chipset.

3. The method according to claim 1 , further comprising, if at least one of the second set of geo-fence rules is broken and indicative of breaking at least one of the first set of geo-fence rules, switching the second chipset to a continuous update mode, and monitoring, with the first chipset, a geo-fence area to the determine if the UE moves outside of the geo-fence area, and upon the UE moving outside of the geo-fence area, generating another second set of geo-fence rules.

4. The method according to claim 1 , wherein the first chipset includes at least one first processor for controlling peripherals of the UE and at least one geo-fence module for generating the first set of geo-fence rules and the second set of geo-fence rules and controlling drivers of the UE, and the second chipset includes at least one low power clock and at least one second processor including at least one navigation ranging module, the at least one second processor programmed to detect if at least one of the second set of geo-fence rules has been broken.

5. The method according to claim 4 , wherein powering down the first chipset comprises powering down the at least one geo-fence module.

6. The method according to claim 4 , wherein powering down the first chipset comprises powering down the at least one geo-fence module and the at least one first processor of the first chipset.

7. The method according to claim 6 , wherein powering down the first chipset further comprises powering down at least one clock of the second chipset, other than the at least one low power clock.

8. The method according to claim 4 , further comprising:
determining, by the second chipset, if the second set of geo-fence rules should be redefined to include a long-term power down duration of the first chipset if the UE is a predetermined distance away from breaking the first set of geo-fence rules;
powering down the first chipset for the long-term power down duration; and
powering up the at least one low power clock of the second chipset for the long-term power down duration.

9. The method according to claim 1 , wherein the second set of geo-fence rules is based on one of a convex hull configuration, a circle configuration, and a polygon configuration.

10. A user equipment (UE) comprising:
at least two chipsets; and
memory coupled to the at least two chipsets and configured to store instructions, which, when executed by the at least two chipsets, causes the at least two chipsets to perform operations comprising:
generating, with a first chipset, a first set of geo-fence rules and a second set of geo-fence rules, which are a simplified subset of the first set of geo-fence rules;
transmitting the second set of geo-fence rules to a second chipset;
powering down the first chipset;
detecting if at least one of the second set of geo-fence rules has been broken; and
if at least one of the second set of geo-fence rules is broken, powering up the first chipset to determine if the at least one broken second rule is indicative of breaking at least one rule of the first set of geo-fence rules.

11. The UE according to claim 10 , wherein the at least two chipsets are programmed to perform operations further comprising, if at least one of the second set of geo-fence rules is broken and not indicative of breaking at least one of the first set of geo-fence rules, generating, with the first chipset, another second set of geo-fence rules which are a simplified subset of the first set of geo-fence rules, and transmitting the another second set of geo-fence rules to the second chipset.

12. The UE according to claim 10 , wherein the at least two chipsets are programmed to perform operations further comprising, if at least one of the second set of geo-fence rules is broken and indicative of breaking at least one of the first set of geo-fence rules, switching the second chipset to a continuous update mode and monitoring, with the first chipset, a geo-fence area to the determine if the UE moves outside of the geo-fence area, and upon the UE moves outside of the geo-fence area, generating another second set of geo-fence rules.

13. The UE according to claim 10 , wherein the first chipset includes at least one first processor for controlling peripherals of the UE and at least one geo-fence module for generating the first set of geo-fence rules and the second set of geo-fence rules and controlling drivers of the UE, and the second chipset includes at least one low power clock and at least one second processor including at least one navigation ranging module, the at least one second processor programmed to detect if at least one of the second set of geo-fence rules has been broken.

14. The UE according to claim 13 , wherein powering down the first chipset comprises powering down the at least one geo-fence module.

15. The UE according to claim 13 , wherein powering down the first chipset comprises powering down the at least one geo-fence module and the at least one first processor of the first chipset.

16. The UE according to claim 15 , wherein powering down the first chipset further comprises powering down at least one clock of the second chipset, other than the at least one low power clock.

17. The UE according to claim 13 , wherein the at least two chipsets are programmed to perform operations further comprising:
determining, by the second chipset, if the second set of geo-fence rules should be redefined to include a long-term power down duration of the first chipset if the UE is a predetermined distance away from breaking the first set of geo-fence rules;
powering down the first chipset for the long-term power down duration; and
powering up the at least one low power clock of the second chipset for the long-term power down duration.

18. The UE according to claim 10 , wherein the second set of geo-fence rules is based on one of a convex hull configuration, a circle configuration, and a polygon configuration.

19. A user equipment (UE) comprising:
at least two chipsets; and
memory coupled to the at least two chipsets and configured to store instructions, which, when executed by the at least two chipsets, causes the at least two chipsets to perform operations comprising:
generating, with a first chipset, a first geo-fence area of the UE;
powering down the first chipset;
