1. A method comprising, at a mobile station:
- receiving preliminary positioning assistance data for one or more indoor regions determined to be at or nearby to an estimated location of said mobile station;
transmitting a request for positioning assistance data for a first one of said one or more indoor regions, wherein said transmitting said request is in response to a determination that said mobile station is in said first one of said one or more indoor regions based, at least in part, on a signal characteristic measurement for a wireless signal received by said mobile station from a first transmitter identified in at least a portion of said preliminary positioning assistance datareceiving positioning assistance data for said first one of said one or more indoor regions in response to said request for positioning assistance data, said positioning assistance data comprising;
encoded metadata corresponding to at least one of an electronic map for said first one of said one or more indoor regions;
an access point locator for said first one of said one or more indoor regions;
or both; and
providing at least a portion of said positioning assistance data to;
a positioning function;
a navigation function;
a location based service function;
or a combination thereof.

1. A method comprising, at a mobile station:
-
receiving preliminary positioning assistance data for one or more indoor regions determined to be at or nearby to an estimated location of said mobile station; transmitting a request for positioning assistance data for a first one of said one or more indoor regions, wherein said transmitting said request is in response to a determination that said mobile station is in said first one of said one or more indoor regions based, at least in part, on a signal characteristic measurement for a wireless signal received by said mobile station from a first transmitter identified in at least a portion of said preliminary positioning assistance data receiving positioning assistance data for said first one of said one or more indoor regions in response to said request for positioning assistance data, said positioning assistance data comprising;
encoded metadata corresponding to at least one of an electronic map for said first one of said one or more indoor regions;
an access point locator for said first one of said one or more indoor regions;
or both; andproviding at least a portion of said positioning assistance data to;
a positioning function;
a navigation function;
a location based service function;
