Figure PCTCN2019093394-appb-000001
EDT数据传输
在LTE中引入了EDT数据传输，在EDT数据传输过程中，UE可能始终保持在空闲(idle)状态或者悬挂(suspend)状态或者非激活(inactive)状态，完成上行和/或下行的EDT数据传输。
EDT数据传输可以采用控制面传输方案，如图2-1所示，包括如下步骤：
1、UE向eNB发送RRC早数据请求(RRCEarlyDataRequest)消息。
这里，RRCEarlyDataRequest消息也可以称为EDT数据传输请求消息，或小数据传输请求消息，或小数据包传输请求消息，或小包数据传输请求消息。
这里，RRCEarlyDataRequest消息携带如下信息：S-TMSI、establishmentCause、dedicatedInfoNAS。dedicatedInfoNAS即为EDT数据(或者称为小数据、或小数据包、或小包数据)。
2、eNB向MME发送初始UE消息(Initial UE message)，初始UE消息携带NAS消息(NAS message)。
3、MME与S-GW之间修改承载(Modify Bearer)。
4、MME向S-GW发送上行数据(Uplink data)。
5、S-GW向MME发送下行数据(Downlink data)。
6a、下行NAS传输(DL NAS TRANSPORT)。
6b、建立连接(CONNECTION)。
7、eNB向UE发送RRC早数据完成(RRCEarlyDataComplete)消息。
这里，RRCEarlyDataComplete消息携带dedicatedInfoNAS，dedicatedInfoNAS即为EDT数据(或者称为小数据、或小数据包、或小包数据)。
8、MME与S-GW之间修改承载(Modify Bearer)，eNB和MME之间执行S1释放流程(S1 release procedure)。
EDT数据传输也可以采用用户面传输方案，如图3所示，包括如下步骤：
1、UE向eNB发送RRC连接恢复请求(RRCConnectionResumeRequest)消息以及上行数据(Uplink data)。
这里，RRCConnectionResumeRequest携带如下信息：resumeID、resumeCause、shortResumeMAC-I。
2、eNB向MME发送UE上下文恢复请求(UE Context Resume Request)消息。
3、MME与S-GW之间修改承载(Modify Bearer)。
4、MME向eNB发送UE上下文恢复响应(UE Context Resume Response)消息。
5、eNB向S-GW发送上行数据(Uplink data)。
6、S-GW向eNB发送下行数据(Downlink data)。
7、MME与S-GW之间修改承载(Modify Bearer)，eNB和MME之间执行S1悬挂流程(S1Suspend procedure)。
8、eNB向UE发送RRC连接释放(RRCConnectionRelease)消息和下行数据(Downlink data)。
这里，RRCConnectionRelease消息携带如下信息：releaseCause、releaseID、NCC。
需要说明的是，图2-1和图3是以LTE为例进行说明，NR与LTE同理，区别在于，对于NR需要将eNB替换为gNB，移动管理功能实体(MME，Mobility Management Entity)替换为接入和移动性管理功能实体(AMF，Access and Mobility Management Function)，服务网关(Serving Gateway，S-GW)替换为用户平面功能实体(UPF，User Plane Function)。
对于UE侧而言，UE NAS(即终端的NAS层)会传递NAS消息给UE AS(即终端的AS层)，UE AS收到UE NAS的NAS消息(即UE AS收到UE NAS的触发)后启动EDT初始化过程(包含启动定时T300)，UE会在随机接入过程的Msg3里面携带NAS消息(该NAS消息携带上行数据)。如果UE AS发送完Msg3后定时器超时，则UE AS通知UE NAS RRC连接失败或者NAS消息传输失败或者上行数据传输失败。UE NAS如果需要触发UE AS再一次传输NAS消息，按照上述过程反复进行。由于NAS消息(或者说上行数据)传输占用Msg3资源，而且使用的是CCCH信道，会出现上行覆盖受限的情况。所以如果通过Msg3携带上行数据，在上行覆盖受限的情况下可能会出现上行数据传输失败。为此提出了本申请实施例的 以下技术方案。
图4为本申请实施例提供的数据传输方法的流程示意图一，如图4所示，所述数据传输方法包括以下步骤：
步骤401：终端通过NAS消息向网络设备发送上行数据。
本申请实施例中，所述终端可以是手机、平板电脑、笔记本、车载终端、穿戴式设备等任意能够与网络进行通信的设备。
本申请实施例中，所述网络设备可以是基站，例如5G基站(即gNB)，4G基站(即eNB)。
本申请实施例中，通过NAS消息向网络设备发送上行数据，属于控制面传输方案来发送上行数据。在一个例子中，采用图2-2所示的控制面传输方案来传输上行数据，图2-2与图2-1的流程一致，图2-2与图2-1的区别在于，图2-1是以LTE为例进行说明，图2-2是以NR为例进行说明。
在本申请一些可选实施方式中，上行数据是指上行的EDT数据，或者小数据，或者小数据包，或者小包数据。上行数据携带在NAS消息中进行传输，进一步，NAS消息是通过Msg3进行传输，以图2-2为例，Msg3是指RRCEarlyDataRequest消息，RRCEarlyDataRequest消息也可以称为小数据传输请求消息，或小数据包传输请求消息，或小包数据传输请求消息，或EDT数据传输请求消息。
步骤402：若所述终端发送所述上行数据失败的次数达到第一门限值，则所述终端执行RRC连接建立过程，通过所述RRC连接建立过程建立专用承载，并通过所述专用承载发送所述上行数据。
本申请实施例中，所述终端的NAS层触发所述终端的AS层发送上行数据给网络设备，并启动第一定时器；若所述第一定时器超时之前所述上行数据未发送完成，则所述终端的AS层通知所述终端的NAS层所述上行数据发送失败。若所述终端发送所述上行数据失败的次数达到第 一门限值，则所述终端执行RRC连接建立过程，通过所述RRC连接建立过程建立专用承载，并通过所述专用承载发送所述上行数据。
举个例子：UE NAS发送NAS PDU给UE AS，并触发UE AS发送RRCEarlyDataRequest消息给基站(如图2-2中的gNB)，UE AS初始化EDT过程时启动第一定时器(如T300)。第一定时器超时，则UE AS通知UE NAS上行数据发送失败或者RRC传输失败。
这里，所述终端发送所述上行数据失败的次数达到第一门限值，可以由所述终端的NAS层确定，也可以由所述终端的AS层确定，以下详细说明。
1)所述终端的NAS层确定发送所述上行数据失败的次数达到第一门限值，所述终端的NAS层通知所述终端的AS层发送RRC连接建立请求消息。
具体地，所述终端的NAS层每次触发所述终端的AS层发送所述上行数据给网络设备后，将第一计数器的值加1；所述终端的NAS层确定所述第一计数器的值达到第一门限值。
举个例子：UE NAS维护一个计数器(即第一计数器)，每次触发UE AS发送携带上行数据的NAS消息，计数器就加1。当计数器的值大于一定门限(即第一门限值)，则UE NAS通知UE AS发送RRC连接建立请求消息，回落到RRC连接建立过程，通过专用承载(或者说专用信道)传输上行数据。
需要说明的是，所述第一计数器的计数是针对同一上行数据的发送。举个例子：第一计数器是针对同一个NAS消息，适用于NAS消息重传的计数。如果NAS消息发生变更，例如消息变长，则第一计数器被重置。
2)所述终端的AS层确定发送所述上行数据失败的次数达到第一门限值，所述终端的AS层发送RRC连接建立请求消息，并通知所述终端的NAS 层执行RRC连接建立过程。
具体地，所述终端的AS层每次发送所述上行数据给网络设备后，将第二计数器的值加1；所述终端的AS层确定所述第二计数器的值达到第一门限值。
举个例子：UE AS维护一个计数器(即第二计数器)，UE AS传输携带上行数据的NAS消息，则计数器加1，当计数器的值大于一定门限(即第一门限值)，则UE AS通知UE NAS，回落到RRC连接建立过程，通过专用承载(或者说专用信道)传输上行数据。
需要说明的是，所述第二计数器的计数是针对同一上行数据的发送。举个例子：第二计数器是针对同一个NAS消息，适用于NAS消息重传的计数。如果NAS消息发生变更，例如消息变长，则第二计数器被重置。
本申请实施例中，所述第一门限值可以由终端自定义，或者网络设备通过系统广播消息来配置，或者系统自定义。
图5为本申请实施例提供的数据传输方法的流程示意图二，如图5所示，所述数据传输方法包括以下步骤：
步骤501：终端接收网络设备发送的第一指示信息，所述第一指示信息用于指示信号质量门限。
本申请实施例中，所述终端可以是手机、平板电脑、笔记本、车载终端、穿戴式设备等任意能够与网络进行通信的设备。
本申请实施例中，所述网络设备可以是基站，例如5G基站(即gNB)，4G基站(即eNB)。
在本申一可选实施方式中，所述第一指示信息携带在系统广播消息中。具体地，网络设备发送系统广播消息，该系统广播消息携带第一指示信息，所述第一指示信息用于指示信号质量门限。
本申请实施例中，所述信号质量包括以下至少之一：参考信号接收功 率(Reference Signal Received Power，RSRP)、参考信号接收质量(Reference Signal Received Quality，RSRQ)、信号与干扰加噪声比(Signal to Interference plus Noise Ratio，SINR)。相应地，所述第一指示信息用于指示以下至少一种信号质量门限：RSRP门限、RSRQ门限、SINR门限。
步骤502：所述终端测量目标小区的第一信号质量，基于测量得到的所述第一信号质量和所述信号质量门限，确定上行数据的发送方式。
本申请实施例中，所述终端测量的第一信号质量包括以下至少之一：测量的RSRP、测量的RSRQ、测量的SINR。
本申请实施例中，若测量得到的所述第一信号质量大于等于所述信号质量门限，则所述终端确定通过EDT方式向网络设备发送所述上行数据；若测量得到的所述第一信号质量小于所述信号质量门限，则所述终端确定通过专用承载向网络设备发送所述上行数据。
这里，EDT方式可以参照图2-1至图2-2所示的传输方案。专用承载是指终端进入连接态，通过专用承载(或者说专用信道)发送上行数据。本申请实施例中，上行数据是指上行的EDT数据，或者小数据，或者小数据包，或者小包数据。
本申请实施例中，若测量得到的所述第一信号质量小于所述信号质量门限，则所述终端的AS层通知所述终端的NAS层不支持上行数据的传输；若测量得到的所述第一信号质量大于等于所述信号质量门限，则所述终端的AS层通知所述终端的NAS层支持上行数据的传输。如此，所述终端的NAS层可以根据是否支持上行数据的传输，决定是否继续出发所述终端的AS层发送NAS消息。
本申请实施例的技术方案，适用于LTE EDT的场景，也适用于NR EDT的场景。另一方面，适用于4步随机接入过程中的EDT数据传输，也可以适用于2步随机接入过程中的EDT数据传输。

发送单元601，用于通过NAS消息向网络设备发送上行数据；若所述发送所述上行数据失败的次数达到第一门限值，则执行RRC连接建立过程，通过所述RRC连接建立过程建立专用承载，并通过所述专用承载发送所述上行数据。
在一实施方式中，所述发送单元601包括NAS层(图中未示出)和AS层(图中未示出)；其中，
