Communicating mapping application data between electronic devices

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.
