Abstract

Methods and apparatus for an environment analysis tool on a mobile device which may construct a model of the surrounding environment in order to determine whether or not characteristics of the model implicate a degradation in wireless signal quality. In response to an analysis of the constructed model to determine signal quality, the environment analysis tool may alter the behavior of any number of hardware or software functions to avoid or reduce efforts to receive or use the affected signal over the duration of the mobile device's presence within the environment with the signal-degrading characteristics.

First claim

What is claimed is:

1. A method, comprising:
performing, by a mobile computing device:
receiving mapping information for a surrounding environment of the mobile computing device;
determining, based on height values included in the mapping information, one or more spatial dimensions for one or more particular objects in the surrounding environment;
determining, based on analyzing the one or more spatial dimensions for the one or more particular objects with respect to a signal type, whether reception on the mobile computing device of a signal of the signal type could be affected by the one or more particular objects; and
modifying operation of a component on the mobile computing device in response to said determining that reception of the signal of the signal type could be affected by the one or more particular objects,
wherein the component on the mobile computing device is related to processing the signal, and
wherein the operation of the component on the mobile device is modified to search less frequently for the signal or the operation of the component on the mobile device is modified to operate in a low-power mode.

2. The method of claim 1 , wherein the mapping information comprises two-dimensional mapping information, wherein the mapping information comprises three-dimensional mapping information, and wherein the mapping information comprises vector graphics data for rendering on the mobile computing device.

3. The method of claim 1 , wherein the mapping information comprises two-dimensional mapping information and three-dimensional mapping information, and wherein said determining the one or more spatial dimensions for one or more particular objects comprises:
generating a model of the surrounding environment, wherein said generating comprises:
identifying a footprint of an object of the one or more particular objects from the two-dimensional mapping information;
correlating the footprint to a corresponding area in the three-dimensional mapping information to find a height value;
determining, based on the height value, one of the one or more spatial dimensions;
extruding the footprint to the height value; and
repeating said identifying, said correlating, said determining, and said extruding for each of the one or more particular objects.

4. The method of claim 3 , wherein said determining whether reception of a signal of the signal type is affected comprises determining that the model comprises an urban canyon.

5. The method of claim 4 , wherein said modifying the operation of the component of the mobile computing device further comprises modifying the operation of the component of the mobile computing device to search less frequently for the signal while inside of the urban canyon.

6. The method of claim 4 , wherein said modifying the operation of the component of the mobile computing device further comprises modifying the operation of the component of the mobile computing device to operate circuitry for processing the signal in a low-power mode while inside of the urban canyon.

7. The method of claim 6 , further comprising:
determining, based on sensor data, when the urban canyon has been exited, wherein the sensor data is collected from the mobile computing device; and
in response to determining when the urban canyon has been exited, transitioning the circuitry for processing the signal out of the low-power mode.

8. The method of claim 5 , further comprising:
determining, based on sensor data, when the urban canyon has been exited, wherein the sensor data is not received from a remote source; and
in response to determining when the urban canyon has been exited, searching more frequently for the signal.

9. A non-transitory computer-readable storage medium storing program instructions, wherein the program instructions are executable on a mobile computing device to implement:
receiving mapping information for a surrounding environment of the mobile computing device;
determining, based on height values included in the mapping information, one or more spatial dimensions for one or more particular objects in the surrounding environment;
determining, based on analyzing the one or more spatial dimensions for the one or more particular objects with respect to a signal type, whether reception on the mobile computing device of a signal of the signal type could be affected by the one or more particular objects; and
modifying operation of a component on the mobile computing device in response to said determining that reception of the signal of the signal type could be affected by the one or more particular objects,
wherein the component on the mobile computing device is related to processing the signal, and
wherein the operation of the component on the mobile computing device is modified to search less frequently for the signal or the operation of the component on the mobile device is modified to operate in a low-power mode.

10. The non-transitory computer-readable storage medium of claim 9 , wherein the mapping information comprises two-dimensional mapping information, wherein the mapping information comprises three-dimensional mapping information, and wherein the mapping information comprises vector graphics data for rendering on the mobile computing device.

11. The non-transitory computer-readable storage medium of claim 9 , wherein the mapping information comprises two-dimensional mapping information and three-dimensional mapping information, and wherein said determining the one or more spatial dimensions for one or more particular objects comprises:
generating a model of the surrounding environment, wherein said generating comprises:
identifying a footprint of an object of the one or more particular objects from the two-dimensional mapping information;
correlating the footprint to a corresponding area in the three-dimensional mapping information to find a height value;
determining, based on the height value, one of the one or more spatial dimensions;
extruding the footprint to the height value; and
repeating said identifying, said correlating, said determining, and said extruding for each of the one or more particular objects.

12. The non-transitory computer-readable storage medium of claim 11 , wherein said determining whether reception of a signal of the signal type is affected comprises determining that the model comprises an urban canyon.

13. The non-transitory computer-readable storage medium of claim 12 , wherein said modifying the operation of the component of the mobile computing device further comprises modifying the operation of the component of the mobile device to search less frequently for the signal while inside of the urban canyon.

14. The non-transitory computer-readable storage medium of claim 12 , wherein said modifying the operation of the component of the mobile computing device further comprises modifying the operation of the component of the mobile computing device to operate circuitry for processing the signal in a low-power mode while inside of the urban canyon.

15. The non-transitory computer-readable storage medium of claim 14 , wherein the program instructions are further executable by the mobile computing device to perform:
determining, based on sensor data, when the urban canyon has been exited, wherein the sensor data is collected from the mobile computing device; and
in response to determining when the urban canyon has been exited, transitioning the circuitry for processing the signal out of the low-power mode.

16. The non-transitory computer-readable storage medium of claim 13 , wherein the program instructions are furthe
