具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
图1是根据一示例性实施例示出的一种下行数据传输方法的应用场景示意图。本公开提供的下行数据传输方式应用在基站与UE之间，如图1所示，该场景下可以包括多个基站以及多个UE，UE在基站的覆盖范围内移动，有可能移动至其他基站(图中以一个其他基站为例)的无线通知区域，即其他基站的覆盖范围，当基站需要对该UE进行下行数据 传输时，可采用本方案提供的下行数据传输方法，后续的技术方案针对同一个UE进行说明。
图2是根据一示例性实施例示出的一种下行数据传输方法实施例一的流程图。如图2所示，该方法用于在基站侧，该基站可以是宏基站、微基站、射频拉远、直放站或者室内分布系统等类型的站点，对此本方案不做限制。该下行数据传输方法包括以下步骤：
在步骤S101中，在无线通知区域发送寻呼消息，寻呼消息包括需要向UE发送的数据。
在步骤S102中，接收UE返回的接收确认消息，接收确认消息用于指示UE成功接收所述数据。
在上述步骤中，当网络侧存在数据需要传输给某个UE时，对于正在连接态的UE则可以直接下发数据，若UE未连接或者非活跃状态的，则可以将待发送的下行数据携带在寻呼消息中进行发送，一般是广播方式，该数据可以通过UE的标识进行标记，以便接收到该寻呼消息的UE可以确定数据是否是发送给自己的。
可选的，在该方案的具体实现中，基站获取寻呼消息的方式至少包括以下两种：
第一种实现方式，接收其他基站发送的所述寻呼消息。
第二种实现方式，获取寻呼信令，并在所述信令中添加所述数据得到所述寻呼消息。
上述两种方式的含义是：该基站可以接收其他基站发送的寻呼消息，其中包括对UE的寻呼指令以及发送给该UE的下行数据；或者，自己生成的寻呼消息，根据发送数据的需要生成对该UE的寻呼指令，并将待发送的数据增加在寻呼指令中得到该寻呼消息
当基站将该寻呼消息广播或者通过其他基站进行广播后，若UE成功获取到了该数据，则需要向基站返回接收确认消息，以便基站能够确定UE已经正确接收下行数据。
该发送方式优选应用在UE为非活跃状态下。
本公开实施例提供的下行数据传输方法，基站发送给UE的寻呼消息中包括数据，UE接收到寻呼消息，并直接获取到数据，不需要建立连接状态就可以直接得到数据，有效提高数据的传输效率，降低数据传输时延。
图3是根据一示例性实施例示出的一种下行数据传输方法实施例二的流程图，如图3所示，在上述实施例一的基础上，该下行数据传输方法的另一种实现方式包括以下步骤：
在步骤S201中，将寻呼消息发送至其他基站，以使其他基站在对应的通知区域内发送寻呼消息。
在本步骤中，该基站可以在自身广播寻呼消息的同时，将该寻呼消息发送给周围的一个或者多个其他基站，以使这些其他基站将该寻呼消息进行广播。
可选的，该基站也可以接收其他基站的寻呼消息，并对其他基站发送的寻呼消息进行广播，以便UE可以快速接收到数据。
在步骤S202中，接收UE返回的接收确认消息，接收确认消息用于指示UE成功接收 所述数据。
在本步骤中，如果是其他基站接收到UE返回的接收确认消息，则此处的接收UE返回的接收确认消息是通过其他基站转发得到的，即基站接收UE通过其他基站发送的接收确认消息。
同样的，如果广播的是其他基站的寻呼消息，且接收到了UE返回的接收确认消息，也需要将所述接收确认消息发送至所述其他基站。
UE可能会一直进行移动，即远离了最初的寻呼区域，因此为了更快的将数据发送给UE，基站也可以通过周围的其他的基站对UE进行寻呼，即将携带该UE下行数据的寻呼消息发送给其他基站，以使其他基站将该寻呼消息进行广播，以使UE能更快的获取到数据。
同样的，该方案一般是应用于非活跃状态的UE，即RRC_INACTIVE状态，基站在确定UE处于无线资源控制(Radio Resource Control，RRC)连接状态时，不需要对UE进行唤醒，即不需要与UE进行RRC建立过程，将需要发送的数据直接携带在寻呼消息中，对UE进行寻呼的同时实现下行数据的传输，有效提高数据的传输效率，降低了数据的传输时延。
图4是根据一示例性实施例示出的一种下行数据传输方法实施例三的流程图，如图4所示，该方案应用于用户设备侧，该用户设备可以是手机、平板电脑等需要进行上下行数据传输的设备，该下行数据传输方法的具体步骤包括：
在步骤S301中，UE接收基站发送的寻呼消息。
在步骤S302中，检测寻呼消息中是否包括基站向UE发送的数据。
在步骤S303中，若寻呼消息中包括数据，则获取数据并生成接收确认消息，接收确认消息用于指示UE成功接收数据。
在步骤S304中，将接收确认消息发送给基站。
在本方案中，UE可以是未建立连接的状态，也可以是非活跃状态，也称为轻连接状态，依然可以对基站的寻呼消息进行接收，基站发送寻呼消息的方式为广播。
UE在接收到寻呼消息之后，需要检测其中是否包含了发送给自己的下行数据，如果包括则直接获取该数据，生成接收确认消息返回给基站，以使基站知道UE接收到数据，同时可根据寻呼消息中的寻呼指令进行RRC链路建立，以便后续可以继续进行数据传输。
如果该寻呼消息中并没有发送给该UE的数据，且其中的寻呼指令指示是对该UE的寻呼，则UE根据寻呼指令发起无线链路建立过程，建立无线链路以便传输数据
本公开实施例提供的下行数据传输方法，UE在接收到基站的寻呼消息时，检测该寻呼消息中是否携带发送给该UE的下行的数据，该数据可以使用UE的标识进行标记，如果包括，则解码获取该数据，并生成接收确认消息返回给基站，否则根据寻呼指令发起无线链路建立过程，建立无线链路以便传输数据。通过该方式可以有效提高数据的传输效率， 降低数据的传输时延。
综合上述几个实施例技术方案，可知本公开提供一种向处于RRC_INACTIVE状态UE直接传输下行数据的方法。
当网络有数据需要传输给处于RRC_INACTIVE状态的UE并且基站(简称gNB)决定为该UE采用直接传输下行数据的方法时，gNB在无线通知区域内发送无线寻呼信令来寻呼该UE，并且将所需要传输的数据添加在寻呼信令中一起进行传输。为了实现该寻呼，gNB可以向无线通知区域内的所有其他gNB发送该包含数据信息的寻呼信令，其他gNB在收到该寻呼信令后，再将该寻呼信令在自己的覆盖范围内进行广播。
处于RRC_INACTIVE状态的UE在收到无线寻呼信令后，如果该无线寻呼信令包含针对自己的寻呼，那么该UE会进一步检查该寻呼信令是否包含数据部分，如果包含数据部分，那么UE继续接收无线寻呼信令中包含的发送给自己的数据，如果不包含数据部分，那么该UE会尝试与gNB建立RRC连接。在接收到数据后，UE还可以选择向发送该寻呼信令的基站发送接收确认信令，接收到该确认信令的基站再将该确认信令传输给最开始发送寻呼信令的gNB，以便gNB知道数据传输完毕。
通过该种方式，5G网络中，处于RRC_INACTIVE状态的UE可以不用转变成RRC_CONNECTED状态就可以进行数据的接收。提高的数据的传输效率，降低了数据的传输时延。
