Abstract

The subject matter disclosed herein relates to systems, methods, apparatuses, devices, articles, and means for updating radio models. For certain example implementations, a method for one or more server devices may comprise receiving at one or more communication interfaces at least one measurement that corresponds to a position of a first mobile device within an indoor environment. At least one radio model that is stored in one or more memories may be updated based, at least in part, on the at least one measurement to produce at least one updated radio model. The at least one radio model and the at least one updated radio model may correspond to the indoor environment. The at least one updated radio model may be transmitted to enable a second mobile device to use the at least one updated radio model for positioning within the indoor environment. Other example implementations are described herein.

Claims

1. A method for providing updated indoor graph information to mobile devices from a server, the method comprising:

receiving an indication of a position of a first mobile device within an indoor environment at the server;

identifying, at the server, a conflict between the position of the first mobile device and at least one graph that corresponds to the indoor environment by comparing the position of the first mobile device with the at least one graph to identify the conflict;

updating, at the server, the at least one graph that corresponds to the indoor environment to produce updated graph information associated with the indoor environment, the updating being responsive to the conflict being identified a threshold number of times based on information received from a plurality of mobiles devices providing indications of the positions of the mobile devices within the indoor environment; and

transmitting the updated graph information associated with the indoor environment to a second mobile device to enable the second mobile device to use the updated graph information for positioning within the indoor environment;

wherein identifying the conflict between the position of the first mobile device and the at least one graph that corresponds to the indoor environment comprises comparing the position of the first mobile device with a previous position of the first mobile device to determine whether the first mobile device has moved along a path that does not correspond to a traversable path included in the at least one graph.

2. The method of claim 1 wherein the conflict indicates that the at least one graph does not match a characteristic associated with the indoor environment.

3. The method of claim 2 wherein the position of the first mobile device does not match a position corresponding to a node or edge of the at least one graph;

and wherein updating the at least one graph comprises updating the at least one graph to include a node or edge associated with the position of the first mobile device.

4. A server for providing updated indoor graph information to mobile devices, the server comprising:

means for receiving an indication of a position of a first mobile device within an indoor environment;

means for identifying a conflict between the position of the first mobile device and at least one graph that corresponds to the indoor environment, wherein the means for identifying comprises comparing the position of the first mobile device with the at least one graph to identify the conflict;

means for updating the at least one graph that corresponds to the indoor environment to produce updated graph information associated with the indoor environment, the means for updating comprising means for updating the at least one graph responsive to the conflict being identified a threshold number of times based on information received from a plurality of mobiles devices providing indications of the positions of the mobile devices within the indoor environment; and

means for transmitting the updated graph information associated with the indoor environment to a second mobile device to enable the second mobile device to use the updated graph information for positioning within the indoor environment;

wherein the means for identifying the conflict between the position of the first mobile device and at least one graph that corresponds to the indoor environment comprises means for comparing the position of the first mobile device with a previous position of the first mobile device and means for determining whether the first mobile device has moved along a path that does not correspond to a traversable path included in the at least one graph.

5. The server of claim 4 wherein the conflict indicates that the at least one graph does not match a characteristic of the physical world associated with the indoor environment.

6. The server of claim 5 wherein the position of the first mobile device does not match a position corresponding to a node or edge of the at least one graph;

and wherein the means for updating the at least one graph comprises means for updating the at least one graph to include a node or edge associated with the position of the first mobile device.

7. An article comprising:

at least one storage medium having stored thereon instructions for providing updated indoor graph information to mobile devices, the instructions being executable by one or more processors to;

receive via one or more communication interfaces an indication of a position of a first mobile device within an indoor environment;

identify a conflict between the position of the first mobile device and at least one graph that corresponds to the indoor environment by comparing the position of the first mobile device with the at least one graph to identify the conflict;

update the at least one graph that corresponds to the indoor environment to produce updated graph information associated with the indoor environment, the update being responsive to the conflict being identified a threshold number of times based on information received from a plurality of mobiles devices providing indications of the positions of the mobile devices within the indoor environment; and

transmit the updated graph information associated with the indoor environment to a second mobile device to enable the second mobile device to use the updated graph information for positioning within the indoor environment;

wherein the instructions to cause the one or more processors to identify the conflict between the position of the first mobile device and the at least one graph that corresponds to the indoor environment include instructions to cause the one or more processors to compare the position of the first mobile device with a previous position of the first mobile device and instructions to cause the one or more processors to determine whether the first mobile device has moved along a path that does not correspond to a traversable path included in the at least one graph.

8. The article of claim 7 wherein the conflict indicates that the at least one graph does not match a characteristic of the physical world associated with the indoor environment.

9. The article of claim 8 wherein the position of the first mobile device does not match a position corresponding to a node or edge of the at least one graph;

and wherein the instructions to cause the one or more processors to update the at least one graph include instructions to cause the one or more processors to update the at least one graph to include a node or edge associated with the position of the first mobile device.

10. A server for providing updated indoor graph information to mobile devices, the server comprising:

one or more processors configured to;

receive via one or more communication interfaces an indication of a position of a first mobile device within an indoor environment;

identify a conflict between the position of the first mobile device and at least one graph that corresponds to the indoor environment by comparing the position of the first mobile device with the at least one graph to identify the conflict;
