Server-based mobile device regional candidate position fix mode selection
First Claim
1. A method comprising, with an electronic device:
- for at least one of a plurality of regions corresponding to an environment navigable by a mobile device, selecting an initial candidate position fix mode for use by said mobile device, based at least in part on a proximity of the mobile device to or a presence of the mobile device within one of said plurality of regions;
transmitting initial assistance data to said mobile device, said initial assistance data being indicative of said initial candidate position fix mode;
receiving one or more messages from said mobile device, said one or more messages comprising historical navigation observations or historical signal observations, or some combination thereof; and
transmitting new assistance data to said mobile device, said new assistance data being indicative of a newly determined candidate position fix mode, said newly determined candidate position fix mode being selected based, at least in part, on said one or more messages received from said mobile device, wherein said initial candidate position fix and said newly determined candidate position fix mode are selected from a plurality of wireless signal-based positioning modes comprising;
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 second wireless signals transmitted a satellite-based transmitting device, anda third wireless signal-based positioning mode based on a combination of said first wireless signals and said second wireless signals.

Abstract
Various methods, apparatuses and/or articles of manufacture are provided for use by an electronic device to generate a recommended candidate position fix mode to a mobile device for use in a particular region of an environment. Such a candidate position fix mode may, for example, be 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 second wireless signals transmitted a satellite-based transmitting device, and a third wireless signal-based positioning mode based on a combination of the first wireless signals and the second wireless signals. In certain example implementations, assistance data indicative of at least the candidate position fix mode may be transmitted to the mobile device.
