Abstract

Under the current implementation of GSM (Global System for Mobile Communications) systems, when a user has switched off his mobile phone or is not under network coverage, all calls directed towards him are lost. Unless the user has specially activated his CFNRc (Call Forwarding on Subscriber Not Reachable) feature, and the user is in the vicinity of the forwarded-to-number, the user will have no knowledge of who tried to reach him on his mobile phone when it was switched-off either accidentally or intentionally. Further, unless the user has calls for- warded to a voice.mail and the calling party has left a message correctly, the information is again lost.
