Abstract

See full text

A technique for automatically reconnecting a mobile unit to an emergency operator when the connection therebetween is interrupted is described. In a preferred embodiment, when such a call is dropped, a mobile switching center ('MSC') though which the call is connected detects that the call has been dropped and, after determining that the call is an emergency call, based on the number originally dialed by the mobile unit, automatically reestablishes the connection with the mobile unit, thereby reestablishing the emergency call.
