Mobile device positioning responsive to externally generated regional candidate position fix mode selection

A mobile device comprising:

• a communications transceiver;
• and
• a processing unit to:
• obtain, via said communications transceiver, assistance data indicative of a candidate position fix mode for a partial region of an environment navigable by said mobile device, said candidate position fix mode being selected from a plurality of wireless signal-based positioning modes comprising at least:
• a first wireless signal-based positioning mode based on first wireless signals transmitted by a terrestrial-based transmitting device, a second wireless signal-based positioning mode based on a second wireless signals transmitted a satellite-based transmitting device, and a third wireless signal-based positioning mode based on a combination of said first wireless signals and said second wireless signals;
• and
• in response to a determination that said mobile device is estimated to be located within a threshold proximity of said partial region, affect a positioning function based, at least in part, on said candidate position fix mode.

An apparatus for use in a mobile device, the apparatus comprising:

• means for accessing assistance data indicative of a candidate position fix mode for a partial region of an environment navigable by said mobile device, said candidate position fix mode being selected from a plurality of wireless signal-based positioning modes comprising at least:
• a first wireless signal-based positioning mode based on first wireless signals transmitted by a terrestrial-based transmitting device, a second wireless signal-based positioning mode based on a second wireless signals transmitted a satellite-based transmitting device, and a third wireless signal-based positioning mode based on a combination of said first wireless signals and said second wireless signals;
• and
• means for affecting a wireless signal-based positioning function, based, at least in part, on said candidate position fix mode, in response to a determination that said mobile device is estimated to be located within a threshold proximity of said partial region.

An article comprising:

• a non-transitory computer readable medium having computer implementable instructions executable by a processing unit of a mobile device to:
• obtain assistance data indicative of a candidate position fix mode for a partial region of an environment navigable by said mobile device, said candidate position fix mode being selected from a plurality of wireless signal-based positioning modes comprising at least:
• a first wireless signal-based positioning mode based on first wireless signals transmitted by a terrestrial-based transmitting device, a second wireless signal-based positioning mode based on a second wireless signals transmitted a satellite-based transmitting device, and a third wireless signal-based positioning mode based on a combination of said first wireless signals and said second wireless signals;
• and
• in response to a determination that said mobile device is estimated to be located within a threshold proximity of said partial region, affect a wireless signal-based positioning function based, at least in part, on said candidate position fix mode.
