Abstract: A communication system is provided that alerts a public safety officer to missed Push-to-Talk (PTT) group calls. The communication system allows a public safety officer's radio to record a last stop working time. A public safety network then can search a missed call list associated with the public safety officer and automatically push a notification of missed PTT group calls to the public safety officer's radio when the radio re-joins the public safety network. Based on the notification, the public safety officer can choose to review or replay any missed calls to avoid missing important information.

Abstract translation: 提供一个通信系统，提醒公共安全主管错过一键通（PTT）群组呼叫。 通信系统允许公共安全官员的无线电记录最后一个停止工作时间。 然后，公共安全网络可以搜索与公共安全官员相关的未接来电列表，并且当无线电重新加入公共安全网络时，自动向公共安全官员的无线电推送丢失的PTT组呼叫通知。 根据通知，公安人员可以选择查看或重播任何未接来电，以免丢失重要信息。
