A method of preserving or gracefully concluding wireless calls that are dropped
when service is interrupted in a wireless communication system (100) (e.g.,
due to poor RF coverage). When a mobile unit (108) encounters a service
interruption during a call, an announcement (208) is played inviting remaining
participating unit(s) to hold. After a predetermined waiting time (210, 216),
if service is not re-established to the mobile unit, the remaining unit(s) are
invited (218) to leave a message (e.g., voice mail) for the mobile unit
and connected (220) to a messaging system (126). After message(s)
are concluded, the call is ended (226) or optionally, lo continued (206)
if there is more than one remaining unit. If service is recovered before the waiting
time expires, a service recovery announcement is provided (214) to the remaining
unit(s) and the call continues (206).
