Abstract

The present disclosure relates to systems and processes for efficiently communicating mapping application data between electronic devices. In one example, a first electronic device can act as a proxy between a second electronic device and a map server by receiving a first request for map data from the second user device, determining a set of supplemental data to add to the first request to generate a complete second request for map data, and transmitting the second request to a map server. The first electronic device can receive the requested map data from the map server and transmit the received map data to the second electronic device. In another example, the first electronic device can act as a navigation server for the second electronic device by initially transmitting a full set of route data to the second electronic device and subsequently transmitting route update messages to the second electronic device.

Claims

1. A first electronic device comprising a non-transitory machine readable medium storing a program, the program comprising sets of instructions for:

receiving a first request for map data from a second electronic device;

generating a second request for map data based on the first request for map data, wherein the second request for map data comprises a supplemental set of data not included in the first request for map data;

transmitting the second request for map data to a map server;

receiving map data from the map server; and

transmitting the map data to the second electronic device.

2. The first electronic device of claim 1, wherein the first request for map data and the second request for map data each comprises geographic coordinates of the second electronic device.

3. The first electronic device of claim 1, wherein the first request for map data and the second request for map data each comprises an indication of a type of map data requested by the second electronic device.

4. The first electronic device of claim 1, wherein the supplemental set of data comprises a URL of the map server.

5. The first electronic device of claim 1, wherein the supplemental set of data comprises an HTTP request for the map data.

6. The first electronic device of claim 1, wherein the supplemental set of data comprises a software version of an application stored on the second electronic device.

7. The first electronic device of claim 1, wherein the supplemental set of data comprises a device identifier of the second electronic device.

8. The first electronic device of claim 1, wherein the supplemental set of data comprises one or more properties of the second electronic device.

9. The first electronic device of claim 8, wherein the one or more properties of the second electronic device comprises a resolution of a screen of the second electronic device.

10. The first electronic device of claim 1, wherein the set of instructions for generating the second request for map data based on the first request for map data comprises sets of instructions for:

extracting a set of data from the first request for map data;

determining the supplemental set of data based on the extracted set of data; and

generating the second request for map data, wherein the second request for map data comprises the extracted set of data and the supplemental set of data.

11. The first electronic device of claim 1, wherein the program further comprises a set of instructions for pairing with the second electronic device before receiving the first request for map data from the second electronic device.

12. The first electronic device of claim 11, wherein the program further comprises a set of instructions receiving the supplemental set of data after pairing with the second electronic device and before receiving the first request for map data from the second electronic device.

13. The first electronic device of claim 1, wherein the map data comprises:

one or more map tiles;

a set of geographic coordinates;

routing information from a start location to an end location;

or

traffic data.

14. The first electronic device of claim 1, wherein the first electronic device is a mobile phone and the second electronic device is a watch.

15. A first electronic device comprising a non-transitory machine readable medium storing a program, the program comprising sets of instructions for:

transmitting routing data to a second electronic device, wherein the routing data represents a route from a start location to an end location to be traveled by a user;

determining whether a location of the user has changed;

when the location of the user has changed, generating a route update message representing the change of the location of the user; and

transmitting the route update message to the second electronic device.

16. The first electronic device of claim 15, wherein the routing data comprises a set of directions for navigating the route from the start location to the end location.

17. The first electronic device of claim 16, wherein the route update message excludes the set of directions for navigating the route from the start location to the end location.

18. The first electronic device of claim 15, wherein the routing data comprises a plurality of map tiles corresponding to the route.

19. The first electronic device of claim 18, wherein the route update message excludes the plurality of map tiles corresponding to the route.

20. The first electronic device of claim 15, wherein the route update message comprises a location of the user.

21. The first electronic device of claim 15, wherein the route update message comprises a location of the user on the route.

22. The first electronic device of claim 15, wherein the route update message comprises a timestamp.

23. The first electronic device of claim 15, wherein the route update message comprises a speed of the user.

24. The first electronic device of claim 15, wherein the route comprises a plurality of route segments, and wherein the update message comprises a route segment index value representing a segment of the plurality of route segments associated with the location of the user.

25. The first electronic device of claim 15, wherein the program further comprises a set of instructions receiving the routing data from a map server prior to transmitting the routing data to the second electronic device.

26. The first electronic device of claim 15, wherein the set of instructions for determining whether the location of the user has changed comprises sets of instructions for:

determining, at the first electronic device, a location of the first electronic device; and

determining whether the location of the first electronic device is different than a previous location of the first electronic device by more than a threshold amount.

27. The first electronic device of claim 15, wherein the set of instructions for determining whether the location of the user has changed comprises sets of instructions for:

receiving, at the first electronic device, a location of the second electronic device; and

determining whether the location of the second electronic device is different than a previous location of the second electronic device by more than a threshold amount.
