Abstract

The subject matter disclosed herein relates to systems, methods, apparatuses, articles, etc. for mobile device locating in conjunction with localized environments. For certain example implementations, a method may comprise obtaining at a mobile device one or more signals comprising information indicative of a location thereof. The information may be transmitted to one or more servers. A location context identifier (LCI) may be received responsive to the transmitting, with the LCI corresponding to a localized environment at which the mobile device is located. The LCI may be transmitted to the one or more servers. Location-based data may be received responsive to the transmitting of the LCI, with the location-based data being associated with the LCI and pertaining to the localized environment. The location of the mobile device may be determined with respect to the localized environment based, at least in part, on the location-based data. Other example implementations are described herein.

wirelessly transmitting, by the mobile device, the selected at least one received location context identifier to a second server;

in response to said wirelessly transmitting the selected at least one received location context identifier, wirelessly receiving, by the mobile device from the second server, the location-based data, the location-based data corresponding to the selected at least one received location context identifier and comprising local coordinates of a plurality of wireless access devices associated with the localized environment; and

determining the location of the mobile device, by the mobile device, based at least in part upon the location-based data.

2. The method of claim 1 wherein the first server and the second server are a same server.

3. The method of claim 1 wherein the information indicative of the localized environment of the mobile device comprises at least one of an image or a sound.

4. The method of claim 1 wherein the location-based data further comprises one or more of routability information, feasibility information, orientation information, shortest distance information, signal heat map data, portal information, points of interest, annotation information, or position probability data.

5. The method of claim 4 wherein the routability information comprises one or more of a routing graph, annotation information, general building information, feasibility indications, shortest path information, or traversable path information.

6. The method of claim 1, wherein the localized environment of the mobile device comprises an indoor environment corresponding to at least a portion of a building structure in which the mobile device is located.

7. The method of claim 1 wherein the first server is a positioning server and the second server is a location-based-data server.

8. A mobile device comprising:

at least one memory to store instructions; and

one or more processors configured to execute said instructions and render the mobile device to be configured to;

wirelessly transmit, by the mobile device, information indicative of a localized environment of the mobile device to a first server;

wirelessly receive, by the mobile device from the first server and in response to the transmission of the information indicative of the localized environment of the mobile device, one or more location context identifiers associated with the information indicative of the localized environment of the mobile device;

select, by the mobile device, at least one received location context identifier of the one or more received location context identifiers, the selected at least one received location context identifier corresponding to location-based data associated with a particular application;

wirelessly transmit, by the mobile device, the selected at least one received location context identifier to a second server;

wirelessly receive, by the mobile device from the second server and in response to the transmission of the selected at least one received location context identifier, the location-based data corresponding to the selected at least one received location context identifier and comprising local coordinates of a plurality of wireless access devices associated with the localized environment; and

determine the location of the mobile device, by the mobile device, based at least in part upon the location-based data.

9. The mobile device of claim 8 wherein the first server and the second server are a same server.

10. The mobile device of claim 8 wherein the information indicative of the localized environment of the mobile device comprises at least one of an image or a sound.

11. The mobile device of claim 8 wherein the location-based data further comprises one or more of routability information, feasibility information, orientation information, shortest distance information, signal heat map data, portal information, points of interest, annotation information, or position probability data.

12. The mobile device of claim 11 wherein the routability information comprises one or more of a routing graph, annotation information, general building information, feasibility indications, shortest path information, or traversable path information.

13. The mobile device of claim 8, wherein the localized environment of the mobile device comprises an indoor environment corresponding to at least a portion of a building structure in which the mobile device is located.

14. A mobile device comprising:
