摘　　要：为了对基于蜂窝物联网技术的业务续航时长进行研究,首先给出了物联网业务的续航时长评估方法,随后运用该方法得出了低频次周期性上报业务、高频次事件触发上报业务以及下行时延敏感业务这三种典型物联网业务的续航时长,最后分析了业务触发方式、心跳机制、节电方式等影响续航时长的关键因素。The battery life of application services based on Cellular IoT（C-IoT） technology is investigated. Firstly, the evaluation method of battery life for IoT application services is presented. Then, the method is used to derive the battery life of three typical IoT application services, including periodically low-frequency reporting service, highfrequency event-trigger reporting service and delay-sensitive service. Finally, the key factors to affect the battery life are elaborated, including service trigger mode, heartbeat mechanism and power saving mode.
