    • A user equipment (UE) may send a non-voice emergency services (NOVES) message to a public safety access point (PSAP). If the UE does not receive an acknowledgement that the PSAP received the NOVES message, the UE may buffer the NOVES message and periodically re-transmit the NOVES message. The NOVES message may include a counter value that is incremented with each successive transmission. The PSAP may determine if the PSAP or another PSAP has received the NOVES message previously. In some embodiments, the UE may change an interval between re-transmissions if the UE receives a partial acknowledgement from an operator network indicating that the operator network has received the NOVES message but that the PSAP is unavailable. Embodiments also provide an emergency module hosted at the operator network to store and forward the NOVES message to the PSAP.
    • 用户设备(UE)可以向公共安全接入点(PSAP)发送非语音紧急服务(NOVES)消息。 如果UE没有接收到PSAP接收到NOVES消息的确认,则UE可以缓冲NOVES消息并周期性地重新发送NOVES消息。 NOVES消息可以包括随每个连续传输递增的计数器值。 PSAP可以确定PSAP或其他PSAP是否先前已经接收到NOVES消息。 在一些实施例中,如果UE从运营商网络接收到指示运营商网络已经接收到NOVES消息但是PSAP不可用的部分确认,则UE可以改变重传之间的间隔。 实施例还提供在运营商网络上托管的紧急模块,以将NOVES消息存储并转发到PSAP。
