First Claim
Patent Images
1. A method comprising, at a mobile station:
- transmitting a request, via a communication network, to a first repository device corresponding to at least a first one of two or more identifiers, the request to indicate at least a portion of a region that includes a rough location estimate of the mobile device and to request a stored description or characterization of an environment comprising the at least a portion of the region;
receiving the stored description or characterization of the environment from the first repository in response to the request, the stored description or characterization of the environment indicating one or more locations of one or more wireless transmitters in the environment;
generating positioning assistance data at the mobile station for use in providing a location-based service based, at least in part, on the stored description or characterization;
transmitting at least a second one of said two or more identifiers to a second repository device over a wireless communication network; and
in response to transmission of said at least a second one of said file location identifiers, receiving descriptions of one or more transmitters located in or transmitting into the area including said rough location.

14. A mobile station comprising:
-
a network interface; and a processor to; initiate transmission of a request through said network interface to a first repository device corresponding to at least one a first of two or more identifiers, the request to indicate at least a portion of a region that includes a rough location estimate of the mobile device and to request a stored description or characterization of an environment comprising the at least a portion of the region; obtain the stored description or characterization of the environment received from said network interface in response to the request, the stored description or characterization of the environment indicating one or more locations of one or more wireless transmitters in the environment; generate positioning assistance data for use in providing a location-based service at the mobile station based, at least in part, on the stored description or characterization; transmit at least a second one of said two or more identifiers to a second repository device over a wireless communication network; and in response to said transmit of said at least a second one of said file location identifiers, receive descriptions of one or more transmitters located in or transmitting into the area including said rough location. - View Dependent Claims (15, 16, 17, 18)

19. An article comprising:
a non-transitory storage medium having machine-readable instructions stored thereon which are executable by a special purpose computing apparatus in a mobile station to; initiate transmission of a request from the mobile station to a first repository device according to at least a first one of two or more identifiers, the request to indicate at least a portion of a region that includes a rough location estimate of the mobile device and to request a stored description or characterization of an environment comprising the at least a portion of the region; obtain the stored description or characterization of the environment in response to the request, the stored description or characterization of the environment indicating one or more locations of one or more wireless transmitters in the environment; generate positioning assistance data at the mobile station for use in providing a location-based service at the mobile station based, at least in part, on the stored description or characterization; transmit at least a second one of said two or more identifiers to a second repository device over a wireless communication network; and in response to said transmit of said at least a second one of said file location identifiers, receive descriptions of one or more transmitters located in or transmitting into the area including said rough location. - View Dependent Claims (20, 21, 22)

23. An apparatus comprising:
-
means for transmitting a request from a mobile station, via a communication network, to a first repository device according to at least a first one of two or more identifiers, the request to indicate at least a portion of a region that includes a rough location estimate of the mobile device and to request a stored description or characterization of an environment comprising the at least a portion of the region; means for receiving the stored description or characterization of the environment in response to the request, the stored description or characterization of the environment indicating one or more locations of one or more wireless transmitters in the environment; means for generating positioning assistance data at the mobile station for use in providing a location-based service at the mobile station based, at least in part, on the stored description or characterization; means for transmitting at least a second one of said two or more identifiers to a second repository device over a wireless communication network; and means for receiving descriptions of one or more transmitters located in or transmitting into the area including said rough location in response to transmission of said at least a second one of said file location identifiers.
