| Zusammenfassung: | 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
). |
