下面首先对本公开实施例提供的方案涉及的内容进行介绍。
目前在研究Ambient IoT设备如何接入5G网络进行通信,从而实现5G网络万物互联的目标。其中,由于Ambient IoT设备的功耗、复杂度等非常有限,所以相关技术定义的用户设备(User Equipment,UE)通过注册和建立协议数据单元(Protocol Data Unit,PDU)会话来传输数据的方式并不适合能力非常受限的Ambient IoT设备的数据传输,需要研究新的适合Ambient IoT设
备的数据传输方法。具体的,关于Ambient IoT场景和目前的UE数据传输机制介绍如下:
(1)Ambient IoT场景;
相关技术中对Ambient IoT场景进行了研究。Ambient IoT可广泛应用于自动化物流、智能电网、生产制造中的工厂内部物流、智能家居中的传感数据上报等场景。具体比如:自动化仓储场景,可通过Ambient IoT技术在货物入库和出库时进行清点。其中,Ambient IoT设备往往自身没有能量或者仅仅具有非常有限的能量,一般复杂度和成本非常低,传输的数据量非常小(例如仅需上报标签信息)且频率非常低(例如可能仅仅进行一次数据传输)。
(2)目前的UE数据传输机制;
目前定义的UE数据传输机制,需要UE注册到网络中,并建立PDU会话之后才能进行数据传输,网络针对每一个UE需要维护其上下文信息。虽然针对窄带物联网(Narrow Band Internet of Things,NB-IoT)设备,已定义了一些优化的小数据传输方法(如控制面小数据传输),但是无论何种优化方法都需要UE注册并建立PDU会话之后才能进行。
基于以上,本公开实施例提供了一种数据传输方法、装置及设备,用以解决相关技术中无法准确进行Ambient IoT设备的数据传输的问题。其中,方法、装置及设备是基于同一申请构思的,由于方法、装置及设备解决问题的原理相似,因此方法、装置及设备的实施可以相互参见,重复之处不再赘述。
