WAYPOINTS FOR LAST KNOWN NETWORK CONNECTIVITY
Abstract:
Waypoints can be automatically created by monitoring network wireless signal strength to help a user of a mobile device in a non-urban location to find a previous location with known network connectivity and make emergency calls. In some embodiments, a backtrack route is displayed on the mobile device to the closest previous location with network connectivity. In some embodiments, for privacy considerations, access to waypoint information stored in a secured storage/database is restricted based on the determination of location state, and backtrack routes are displayed in stages.
