Abstract
A phone sends information about its whereabouts periodically to a receiving part. The receiving part can then report the last location or information about the last known location of the phone. The query can return a map of both coarse and fine. This allows determining the location of the phone, even when the phone is off or not receiving cell service. A special message can be to the phone, indicating that the phone is trying to be found. This puts the phone into an “im lost” mode, from which it does not recover until a code is entered.
