Abstract

A mobile device comprising at least one processor configured to perform acts of obtaining position information for at least first and second positions of the mobile device along a route; obtaining communication quality information for at least a third position of the mobile device, the communication quality information calculated based on the route and the obtained position information; and causing the mobile device to display the obtained communication quality information.

Claims

1. A mobile device, comprising:

at least one processor configured to perform;

prior to determining a destination of a route, obtaining, based on a signal generated by a second device different from the mobile device, position information for at least first and second positions of the mobile device along the route;

determining a mode of transportation using data obtained by a sensor on the mobile device;

determining, based on the determined mode of transportation, whether to obtain communication quality information for at least a third position of the mobile device;

when it is determined to obtain the communication quality information, obtaining the communication quality information for at least the third position of the mobile device, the communication quality information calculated based on the route and the obtained position information; and

causing the mobile device to display the obtained communication quality information.

2. The mobile device of claim 1, wherein the causing comprises:

causing the mobile device to display the obtained communication quality information on a map.

3. The mobile device of claim 1, wherein the causing comprises:

causing the mobile device to display the obtained communication quality information together with other information associated with the third position.

4. The mobile device of claim 3, wherein the other information associated with the third position comprises location information associated with the third position and/or time information associated with the third position.

5. The mobile device of claim 1, wherein the causing comprises:

causing the mobile device to display the obtained communication quality information as text.

6. The mobile device of claim 1, wherein obtaining the communication quality information for at least the third position comprises obtaining communication quality information for each of a plurality of positions of the mobile device along the route, and wherein the causing comprises causing the mobile device to display the obtained communication quality information in a time sequence.

7. The mobile device of claim 1, wherein the causing comprises:

causing the mobile device to display the obtained communication quality information using color or shading.

8. The mobile device of claim 1, wherein the generated signal is received by the mobile device from a global positioning system (GPS).

9. The mobile device of claim 1, wherein the generated signal is received by the mobile device from a telecommunications carrier.

10. The mobile device of claim 1, wherein the communication quality information for at least the third position comprises information selected from the group consisting of:

a received signal strength indicator (RSSI), strength of a pilot signal, strength of a reference signal, signal strength of a beacon signal, a channel quality indicator (CQI) corresponding to a signal to noise ratio (SNR), a data rate control (DRC) corresponding to the SNR, a signal to interference ratio (SIR), a signal to interference and noise ratio (SINR), a common pilot channel energy per chip to noise ratio (Ec/No), a common pilot channel energy per chip to noise ratio (Ex/Io), reference signal received power (RSRP), reference signal received quality (RSRQ), and received signal code power (RSCP).

11. The mobile device of claim 1, wherein the communication quality information for at least the third position comprises communication quality information for a plurality of telecommunications carriers.

12. The mobile device of claim 1, wherein the at least one processor is further configured to perform:

identifying the route from a plurality of routes based at least in part on the first position of the mobile device and the second position of the mobile device.

13. The mobile device of claim 12, wherein identifying the route comprises calculating distance between the first position and one or more positions on the route.

14. The mobile device of claim 1, wherein obtaining the communication quality information comprises:

accessing, based on the route and the obtained position information, the communication quality information for at least the third position from among communication quality information stored on the mobile device.

15. The mobile device of claim 1, wherein obtaining the communication quality information comprises:

receiving the communication quality information from the second device different from the mobile device.

16. The mobile device of claim 1, wherein the at least one processor is further configured to perform displaying the communication quality information.

17. The mobile device of claim 1, wherein the mobile device comprises an acceleration sensor.

18. The mobile device of claim 1, wherein the third position of the mobile device is determined based on the route.

19. A method, comprising:

using at least one processor to perform;

prior to determining a destination of a route, obtaining, based on a signal generated by a second device different from the mobile device, position information for at least first and second positions of the mobile device along a route;

determining a mode of transportation using data obtained by a sensor on the mobile device;

determining, based on the determined mode of transportation, whether to obtain communication quality information for at least a third position of the mobile device;

when it is determined to obtain the communication quality information, obtaining the communication quality information for at least the third position of the mobile device, the communication quality information calculated based on the route and the obtained position information; and

causing the mobile device to display the obtained communication quality information.

20. At least one non-transitory computer readable storage recording medium storing a program that, when executed by at least one computer, causes the at least one computer to perform:

prior to determining a destination of a route, obtaining, based on a signal generated by a second device different from the mobile device, position information for at least first and second positions of the mobile device along a route;

determining a mode of transportation using data obtained by a sensor on the mobile device;

determining, based on the determined mode of transportation, whether to obtain communication quality information for at least a third position of the mobile device;

when it is determined to obtain the communication quality information, obtaining the communication quality information for at least the third position of the mobile device, the communication quality information calculated based on the route and the obtained position information; and

causing the mobile device to display the obtained communication quality information.
