1. A method for determining a location of a mobile station, comprising:
- quasi-periodically determining that received signal strength of a signal received from at least one wide area device, local area device, or personal area network device is below a predetermined threshold;
scanning for one or more wide area devices, local area devices, or personal area network devices or a combination or sub-combination thereof;
determining background position information for the mobile station based at least in part on signal metrics corresponding to the one or more scanned wide area devices, local area devices, personal area network devices or the combination or sub-combination thereof; and
storing the background position information.

9. An mobile station for determining location, comprising:
-
a processing unit configured to quasi-periodically determine that received signal strength of a signal received from at least one wide area device, local area device, or personal area network device is below a predetermined threshold; a transceiver to scan for one or more wide area devices, local area devices, or personal area network devices or a combination or sub-combination thereof; the processing unit further configured to determine background position information for the mobile station based at least in part on signal metrics corresponding to the one or more scanned wide area devices, local area devices, personal area network devices or the combination or sub-combination thereof; and memory to store the background position information. - View Dependent Claims (10, 11, 12)

13. A non-transitory storage medium comprising machine-readable instructions, for determining a location of a mobile station, stored thereon which, if executed by a processing unit, perform positioning, the instructions comprising:
-
code for quasi-periodically determining that received signal strength of a signal received from at least one wide area device, local area device, or personal area network device is below a predetermined threshold; code for scanning for one or more wide area devices, local area devices, or personal area network devices or a combination or sub-combination thereof; code for determining background position information for the mobile station based at least in part on signal metrics corresponding to the one or more scanned wide area devices, local area devices, personal area network devices or the combination or sub-combination thereof; and code for storing the background position information. - View Dependent Claims (14, 15, 16)
