具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。
以下，术语“网络侧设备”用于表示各种类型的网络侧的设备，例如基站，5G系统中将基站命名为gNB。
用户设备(User Equipment，UE)可以称之为终端(Terminal)、移动台(Mobile Station，简称为“MS”)、移动终端(Mobile Terminal)、移动设备等，包括支持各种类型无线通信技术的用户设备。
实施例一
参见图1，图中示出了一种数据传输方法，具体步骤如下：
步骤101、网络侧设备接收用户设备发送的请求消息和接收所述用户设备发送的数据和缓存状态报告BSR中的一项或多项，其中，所述请求消息至少携带用户设备标识信息；
上述请求消息还可以携带用户设备的验证信息。
上述用户设备标识可以是用户设备的ID。
在本实施例中，可选地，上述请求消息可以是无线资源控制连接恢复请求(Radio Resource Control(RRC)Connection Resume Request)，该RRC Connection Resume Request中可以携带用户设备ID和消息鉴权码，该消息鉴权码用于对用户设备进行验证，例如该消息鉴权码为MAC-I(Message Authentication Code used for data Integrity of signaling messages)信息。
步骤102、网络侧设备根据数据和/或BSR的接收情况，向所述用户设备反馈针对携带所述用户设备标识信息的信息进行数据传输的确认，和/或网络侧设备根据数据和/或BSR的接收情况，向所述用户设备反馈针对携带所述用户设备标识信息的信息连接恢复或建立的确认。
方案1：非激活态进行数据的传输
如果所述网络侧设备仅接收到数据，所述网络侧设备向所述用户设备反馈针对携带用户设备标识信息的信息进行数据传输的确认。
在本实施例中，可选地，网络侧设备通过层2(例如MAC(媒体访问控制)或者链路控制层)反馈针对携带用户设备的标识的信息进行数据传输的确认。
方案2：非激活态进行数据的传输
如果所述网络侧设备收到BSR，且缓存大小不超过阈值(或者小于该阈值)，所述网络侧设备对用户设备进行上行链路授权UL grant。具体地，用户设备收到UL grant进行数据传输，也可以进一步地传输BSR，然后网络侧设备确认数据接收，例如网络侧设备通过底层ACK信令确认数据接收。
上述UL grant可以通过层2(例如MAC(媒体访问控制)或者链路控制层)传递。
上述缓存大小可以表示UE发送数据所需的资源(例如资源块)的大小。
方案3：如果网络侧设备收到BSR，且缓存大小超过阈值(或者不小于该阈值)，网络侧设备恢复所述用户设备的空口连接，向用户设备反馈针对携带移动终端标识的信息进行连接恢复或建立确认。然后，用户设备确认空口连接恢复，进入连接态(Connected)，并上传BSR，包含DRB(数据无线承载)信息。后续为连接态相关调度和数据传输。
方案4：如果网络侧设备收到数据和BSR，且缓存大小不超过阈值(或者小于该阈值)，网络侧设备可以通过一条信息进行确认，以及调度。
具体地，网络侧设备向所述用户设备反馈针对携带的所述用户设备标识信息的信息进行数据传输的确认，以及所述UL grant，通过一个消息进行传递。
方案5：如果网络侧设备收到数据和BSR，且缓存大小超过阈值(或者不小于该阈值)，网络侧设备通过一条信息进行确认，一条信息进行配置。
具体地，网络侧设备先向所述用户设备反馈针对携带的所述用户设备标识信息的信息进行数据传输的确认，然后向所述用户设备反馈针对携带所述移动终端标识的信息进行连接恢复或建立的确认。
需要说明的是，上述阈值可以根据具体情况进行设置，例如根据负载自适应调整设置该阈值，在本实施例中并不限定该阈值的具体范围。
在本实施例中，如果网络侧设备接收到数据，当网络侧设备需要进行上下文更新(context update)时，所述网络侧设备在携带所述用户设备标识信息的信息对应的层2的信息中额外携带一个RRC指示；或者
如果网络侧设备接收到数据和BSR，且缓存大小大于阈值，所述网络侧设备在携带所述用户设备标识信息的信息对应的层2的信息中额外携带一个RRC指示；或者
如果所述网络侧设备接收到BSR，且缓存大小小于阈值，当所述网络侧设备需要进行上下文更新时，所述网络侧设备在携带所述用户设备标识信息的信息对应的层2的信息中额外携带一个RRC指示。
在本实施例中，网络侧设备能够根据接收到的数据和/或BSR的情况，向用户设备反馈针对携带用户设备标识信息的信息进行数据传输和/或连接恢复或建立的确认，通过兼容现有信令设计可扩展地实现用户设备在非激活状态下低开销快速的完成部分类型数据(比如低开销快速的INACTIVE小数据)的传送。
实施例二
参见图2，图中示出了一种数据传输方法，具体步骤如下：
步骤201、用户设备向网络侧设备发送请求消息和向所述网络侧设备发 送数据和缓存状态报告BSR中的一项或多项，其中，所述请求消息至少携带用户设备标识信息；
上述请求消息还可以携带用户设备的验证信息。
步骤202、用户设备接收网络侧设备根据其接收到的数据和/或BSR的情况反馈的携带用户设备标识信息的信息进行数据传输的确认，和/或用户设备接收网络侧设备根据其接收到的数据和/或BSR的情况反馈的携带用户设备标识信息的信息连接恢复或建立的确认。
例如上述请求消息可以是RRC Connection Resume Request，该RRC Connection Resume Request中可以携带用户设备的ID和消息鉴权码，该消息鉴权码用于对用户设备进行验证，例如该消息鉴权码为MAC-I(Message Authentication Code used for data Integrity of signaling messages)信息。
在本实施例中，如果所述网络侧设备仅接收到数据，所述用户设备通过层2(例如MAC(媒体访问控制)或者链路控制层)接收携带所述用户设备标识信息的信息进行数据传输的确认。
在本实施例中，如果所述网络侧设备接收到BSR，且缓存大小小于阈值，当所述用户设备接收到UL grant消息，所述用户设备向所述网络侧设备进行数据传输，所述用户设备收到所述网络侧设备发送的携带所述用户设备标识信息的信息进行数据传输的确认。
在本实施例中，如果所述网络侧设备接收到BSR，且缓存大小大于阈值，所述用户设备收到所述网络侧设备发送的携带所述用户设备标识信息的信息进行连接恢复或建立的确认。
需要说明的是，上述阈值可以根据具体情况进行设置，例如根据负载自适应调整设置该阈值，在本实施例中并不限定该阈值的具体范围。
在本实施例中，通过重用现有的信令实现用户设备在非激活状态下低开销快速的完成部分类型数据(比如低开销快速的INACTIVE小数据)的传送。
实施例三
参见图3，图中示出了数据传输的流程，其中包括方案1(Case 1)、方案2(Case 2)和方案3(Case 3)，图中以用户设备为UE，网络侧设备为gNB为例进行说明。
UE首先会告诉gNB UE ID和MAC-I信息(用于对用户设备UE的验证)，同时可能带上数据(Data)或者缓存状态报告(Buffer Status Report，BSR)，其中UE ID和MAC-I的传递可以基于既有的RRC Connection Resume Request流程。
上述数据和缓存状态报告可以共享传输资源，例如需要放置两个MAC sub-header。这样，gNB收到数据的同时，可以灵活进一步获取数据传输的下一步请求(缓存中待传输数据量多少)。
方案1：UE在非激活状态下进行数据传输。
如果gNB仅收到数据，则向UE反馈UE ID进行确认(例如通过MAC层传递确认消息)；该数据中也可能携带进一步的缓存状态，该缓存状态可以表示UE所需缓存大小。
方案2：UE在非激活状态下进行数据传输。
如果gNB收到BSR(缓存状态报告)，并且缓存大小不超过一个阈值(或者小于一个阈值)，则gNB进行上行授权(UL Grant)，UE收到UL Grant进行数据传递，也可以进一步地传递BSR，gNB确认数据接收，例如通过ACK信令确认数据接收。
方案3：
如果gNB收到BSR，并且缓存大小超过一个阈值(或者不小于一个阈值)，gNB恢复用户设备的空口连接(RRC Connection Resume)。UE确认空口连接恢复(RRC Connection Resume Complete)，进入连接状态(Connected)，并上传BSR，该BSR包含DRB(Data Radio Bearer，数据无线承载)信息，后续为连接态相关调度和数据传输。
需要说明的是，上述方案1、方案2和方案3任何一个情况的发生，或者任何组合的发生都属于本申请保护的范围。
