As a mobile unit approaches a communication dead zone, a call is automatically disconnected in an orderly fashion. The call can be automatically reconnected when the mobile unit exits the communication dead zone. As part of the orderly disconnection, parties to the call are given an audible and/or visual message and/or sensual tactile stimulus letting them know that a dead zone is being approached. The message can also indicate the time before entering the dead zone, and/or what actions will be taken. Similarly, when the mobile unit is about to exit the dead zone, the parties can be given an indication prior to being reconnected.
