Abstract
Methods and apparatuses are provided which may be implemented in various devices for to determine or assist in determining that a mobile station is at one or more particular indoor regions and to provide positioning assistance data and/or the like to the mobile station with regard to at least the one or more particular indoor regions.
Claims32
A method comprising, at a mobile station:
- transmitting a request for a repository device identifier to a directory device, said request for said repository device identifier being indicative of at least a first estimated location of said mobile station;
- receiving a response from said directory device, said response identifying one or more identifiers for preliminary positioning assistance data for one or more indoor regions determined to be at or nearby to said first estimated location;
- transmitting a request for said preliminary positioning assistance data for at least one of said one or more indoor regions to a repository device corresponding to at least one of said identifiers;
- receiving said preliminary positioning assistance data from said repository device;
- determining that said mobile station is in a first one of said one or more indoor regions based, at least in part, on a signal characteristic measurement for a signal received from a transmitter identified in said at least said portion of said preliminary positioning assistance data:
- transmitting a request for positioning assistance data for said first one of said one or more indoor regions to said repository device;
- receiving said positioning assistance data from said repository device, 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, or an access point locator for said first one of said one or more indoor regions;
- decoding said encoded metadata;
- and
- providing at least a portion of said decoded metadata to at least one function.

An apparatus for use in a mobile station, the apparatus comprising:
- means for initiating transmission of a request for a repository device identifier to a directory device, said request for said repository device identifier being indicative of at least a first estimated location of said mobile station;
- means for receiving a response from said directory device, said response identifying one or more identifiers for preliminary positioning assistance data for one or more indoor regions determined to be at or nearby to said first estimated location;
- means for transmitting a request for said preliminary positioning assistance data for at least one of said one or more indoor regions to a repository device corresponding to at least one of said identifiers;
- means for receiving said preliminary positioning assistance data from said repository device;
- means for determining that said mobile station in a first one of said one or more indoor regions based, at least in part, on a signal characteristic measurement for a signal received from a transmitter identified in said at least said portion of said preliminary positioning assistance data:,
- means for initiating transmission of a request for positioning assistance data for said first one of said one or more indoor regions to said repository device;
- means for receiving said positioning assistance data from said repository device, said positioning assistance data com comprising encoded metadata corresponding to at least one of an electronic map for said first one of said one or more indoor regions, or an access point locator for said first one of said one or more indoor regions;
- means for decoding said encoded metadata;
- and
- means for providing at least a portion of said decoded metadata to at least one function.
7 more elements
A mobile station comprising:
- a network interface;
- and
- a processing unit to:
- initiate transmission of a request for a repository device identifier to a directory device via said network interface, said request for said repository device identifier being indicative of at least a first estimated location of said mobile station;
- obtain a response from said directory device via said network interface, said response identifying one or more identifiers for preliminary positioning assistance data for one or more indoor regions determined to be at or nearby to said first estimated location;
- initiate transmission, via said network interface, of a request for said preliminary positioning assistance data for at least one of said one or more indoor regions to a repository device corresponding to at least one of said identifiers;
- receive, via said network interface, said preliminary positioning assistance data from said repository device;
- determine that said mobile station in a first one of said one or more indoor regions based, at least in part, on a signal characteristic measurement for a signal received from a transmitter identified in said at least said portion of said preliminary positioning assistance data:
- initiate transmission of a request for positioning assistance data for said first one of said one or more indoor regions to said repository device via said network interface;
- obtain said positioning assistance data from said repository device via said network interface, 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, or an access point locator for said first one of said one or more indoor regions;
- decode said encoded metadata;
- and
- provide at least a portion of said decoded metadata to at least one function.

An article comprising:
- a non-transitory computer readable medium having stored therein computer implementable instructions that are executable by a special purpose electronic computing device to:
- initiate transmission of a request for a repository device identifier to a directory device, said request for said repository device identifier being indicative of at least a first estimated location of said mobile station;
- obtain a response from said directory device, said response identifying one or more identifiers for preliminary positioning assistance data for one or more indoor regions determined to be at or nearby to said first estimated location;
- initiate transmission of a request for said preliminary positioning assistance data for at least one of said one or more indoor regions to a repository device corresponding to at least one of said identifiers;
- receive said preliminary positioning assistance data from said repository device;
- and
- determine that said mobile station in a first one of said one or more indoor regions based, at least in part, on a signal characteristic measurement for a signal received from a transmitter identified in said at least said portion of said preliminary positioning assistance data;
- and
- initiate transmission of a request for positioning assistance data for said first one of said one or more indoor regions to said repository device;
- obtain said positioning assistance data from said repository device, 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, or an access point locator for said first one of said one or more indoor regions;
- decode said encoded metadata;
- and
- provide at least a portion of said decoded metadata to at least one function.
