Description

一种上行数据的传输方法、装置、设备和计算机存储介质
相关申请的交叉引用
本申请基于申请号为201710223621.X、申请日为2017年04月07日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此以引入方式并入本申请。
技术领域
本发明涉及移动通信技术领域，尤其涉及一种上行数据的传输方法、装置、设备和计算机存储介质。
背景技术
在第三代合作伙伴计划的长期演进(3GPP LTE，3rd Generation Partnership Project Long Term Evolution)系统中，引入了一种新的无线资源控制(RRC)状态，在本文中称为RRC非活动状态(RRC Inactive state)。对该状态下的UE，在网络侧网元(核心网和接入网网元)和UE均保持有该UE的接入层(AS)上下文信息，AS上下文信息包括该UE的信令资源承载(SRB，Signal Resource Bearer)、数据资源承载(DRB，Data Resource Bearer)的配置信息，以及用户面协议层(分组数据汇聚协议(PDCP，Packet Data Convergence Protocol)、无线链路控制(RLC，Radio Link Control))的配置信息和(可能的)状态信息。同时，该UE的行为类似于RRC空闲(IDLE)态的UE，即：在无线接口没有为该状态下的UE分配专用无线资源。网络侧网元为该状态下的UE维护核心网到接入网网元的控制面和用户面连接，即站在核心网的视角，该UE处于RRC连接态(RRC CONNECTED state)。维护该UE的AS上下文信息的接入网网元被称为该UE的锚点网元(anchor 网元，例如anchor gNB)。
在3GPP的讨论中，提出了在非活动状态下的UE发送上行数据的需求。在上述非活动状态发送上行数据的过程中，接入网网元可以将UE的RRC状态转移到RRC连接态或保持在非活动状态。
3GPP还为无线接入网定义了无线通知区域(RAN Notification Area，RNA)，归属于不同的接入网网元的小区可能属于同一个RNA。UE在同一个RNA内移动时，可能驻留(camp)到不同于其anchor网元的接入网网元下的小区，并在该小区内发起RRC连接恢复过程(RRC resume procedure)或在非活动状态发送上行数据。UE在不同于其anchor网元的小区中发起非活动状态上行数据发送时，称新的接入网网元为服务接入网网元，或服务网元(serving Network element)。
当UE发起非活动状态上行数据发送时，如果anchor网元和服务网元属于不同网元，接入网如何决定UE的后续RRC状态，以及如何在该过程中节省UE的电池消耗是一个需要解决的问题。

实施例1
图11描述了相关技术中非活动状态的UE在服务网元发起上行数据传输的过程，此时服务网元和UE的anchor网元不是同一个接入网网元：
第一步：UE在服务网元下的小区(如Cell A)中发起RACH的接入过程，并在RACH的接入过程中的message 3(如果基于四步RACH的接入过程)或message 1(如果基于两步RACH的接入过程)中携带如下信息：
UE的标识和UE的上行数据。UE的标识可表现为UE的上下文标识(UE Context ID)、或其它在接入网的RNA内可以唯一标识该UE的标识、或其它在一个小区内可以唯一标识该UE的标识。
在一实施例中，还可携带：UE的认证信息，例如short MAC-I；
在一实施例中，还可携带：UE发起上行数据传输的原因信息(cause)；
在一实施例中，还可携带：UE上行数据缓冲区的信息(buffer status report，BSR)。
上述的message 3或message1中携带的信息的形式可包括:

以MAC SDU形式复用在MAC PDU中的上行数据。
第二步：接收到第一步所述message 3或message 1的服务网元对接收到的信息进行处理，包括：
识别UE的标识，并通过UE的标识确定UE的anchor网元。
服务网元通过与锚点(anchor)网元间的控制面接口，向所述anchor网元发送获取UE的AS上下文请求消息，例如Retrieve UE context request消息，并在该消息中至少携带如下信息：UE标识。
在一实施例中，该消息中还可携带UE的认证信息、UE当前发起RACH过程的小区的信息(例如PCI：物理小区标识Physical Cell ID)。
第三步：UE的anchor网元处理上述的UE上下文请求消息，包括：
anchor网元确定UE的AS上下文信息，包括UE的接入网层(AS)上下文(context)，并根据UE的AS上下文信息，以及所属的UE认证信息，对UE的身份真实性进行认证检验。
如果UE身份检验通过，则所述UE的anchor网元回应所述的服务网元以获取UE的AS上下文回应消息，例如Retrieve UE Context Response消息，并在该消息中携带UE的上下文信息。
所述的UE的AS上下文信息包括但不限于：AS层的安全上下文、UE的ERAB上下文信息、RRC上下文(包括PDCP、RLC协议配置信息)。
服务网元接收到UE的上下文信息后，在服务网元为UE的SRB和DRB建立相应的无线接入网用户面实体，包括PDCP、RLC实体等。
第四步：服务网元向UE发送消息。
其中，所述消息中携带RRC消息，例如RRC Resume消息；在该RRC消息中指示UE的状态转换信息(state indication)，例如：指示UE转换到RRC连接态、或者指示UE保持在非活动状态(inactive state)、或者指示 UE转换到RRC空闲态(idle)；以及该RRC消息包含UE进行状态转换所必须要的信息和配置。
在一实施例中，在上述发给UE的消息，还可以以MAC CE的形式指示UE的状态转换信息。
需要说明的是，所述的RRC消息或MAC CE不一定在RACH过程中的message 4(基于四步RACH过程)或message 2(基于两步RACH过程)中发送给UE。
第五步：将UE与核心网的连接迁移到服务网元，包括：
服务网元向核心网发起控制面过程，例如path switch过程，将保持在anchor网元的UE与核心网的连接迁移到服务网元。所述的path switch过程还将把anchor网元为UE缓冲的下行数据转移到服务网元。
针对上述方法流程，本实施例提供如下的方法以改进上述的过程。
在上述过程的第三步中，anchor网元还指示服务网元UE状态指示信息，所述UE状态指示信息包括如下信息的至少一种：
anchor网元缓冲的UE的下行数据的大小；所述UE的下行数据大小为每个DRB的下行数据的大小，即(DRB，下行数据大小)的列表，或所有DRB下行数据大小的和；
anchor网元是否缓存有该UE的下行数据；可选的，所述是否有下行数据可按照每个DRB进行指示，即(DRB，是否有下行数据)的列表；
UE的RRC状态转换指示；包括：指示将UE转换为连接态(或称为active态)，或指示将UE转换为空闲态(idle)，或指示将UE保持在非活动态；
在一实施例中，如果指示将UE保持在非活动态，则UE状态指示信息还包括如下信息的至少一种：
指示UE是否需要保持监听下行控制信道(PDCCH)一段时间，以接 收在接入网缓冲的下行数据；
指示UE保持监听下行控制信道的时间长度信息；
指示UE开始监听下行控制信道的时间偏移信息；
指示UE保持监听下行控制信道的DRX信息；所述DRX信息包括DRX周期的大小、DRX周期中监听下行数据传输信令的位置信息；
RRC消息中的一部分，该RRC消息的内容可以包括：将UE状态从非活动态转换到RRC连接态的RRC消息，将UE状态从非活动状态转换到RRC空闲态的RRC消息，以及将UE状态保持在非活动态的RRC消息。服务网元将该RRC消息转发给UE。
在一实施例中，在上述第二步中，服务网元还发送给anchor网元UE上行数据缓冲区的信息；该UE上行数据缓冲区的信息包括：UE通过所述的message 1或message 3中携带的BSR MAC CE、和/或UE是否还有上行数据需要发送、和/或UE需要发送的上行数据的大小、和/或UE需要发送的上行数据的逻辑信道以及每个逻辑信道的数据大小。
在一实施例中，anchor网元根据可根据是否有该UE的缓冲的下行数据或该UE的缓冲的下行数据的大小、和/或该UE的历史行为信息、和/或UE上行数据缓冲区的信息，决定在上述第三步中发送给服务网元的UE状态指示信息的内容。
其中，所述UE的历史行为信息为：anchor网元记录的UE之前的行为，是指UE的上下行数据的业务模型(service model)，即该UE过去一段时间内上下行数据的时间间隔、大小的信息。
这里，由于anchor网元和核心网之间维护了为UE建立的连接，如果核心网有数据要发给接入网，那么anchor网元则知道所述UE的下行数据的缓冲情况的(缓冲的下行数据的大小)。
在上述第四步中，服务网元根据上述第三步中anchor网元提供的UE 状态指示信息，判决后续UE的RRC状态，以及如果将UE保持在非活动状态，是否需要将UE保持监听下行控制信道。
如果需要UE保持监听下行控制信道，服务网元还发送给UE如下信息的至少一种组合：
是否需要监听下行控制信道的指示；
UE监听下行控制信道的时间偏移；
UE监听下行控制信道的时间长度；
UE监听下行控制信道的DRX配置信息。
UE持续监听下行控制信道所使用的RNTI为UE在上述RACH过程中分配的临时RNTI。
可知，服务网元判断UE的后续RRC状态以及保持在非活动态的UE的行为时，需要更完整的信息来完成其判断。而下行数据缓冲区的信息(如上文所述的anchor网元缓冲的UE的下行数据的大小)，以及UE的历史行为信息，是影响UE是否需要进入连接态的重要因素，而这些信息的传递在上述相关技术中是缺失的。
虽然服务网元可以在完成了上述的path switch之后获得UE的缓冲的下行数据大小信息，但是path switch过程需要一定的时间完成，如果在此之前因为缺乏上述anchor网元传递给服务网元的信息，不必要的将UE转换到RRC连接态，或让UE保持监听下行控制信道，都会造成UE电池的浪费。
因此，通过本实施例提供的方法，服务网元可以快速的获得保持在anchor网元的上述信息，即在本实施例中的第三步，从而在path switch完成前便可恰当的决定UE的状态并转换UE的状态。例如：如果没有缓冲的下行数据和上行数据，服务网元可以尽快发送消息指示UE保持在inactive状态并停止监听下行控制信道，这样可以减少UE监听下行控制信道的时 间，从而节省UE的电能消耗。
实施例2
图12为相关技术中四步RACH过程示意图，图13为相关技术中两步RACH过程示意图，以所述四步RACH过程为例说明UE在非活动状态发送上行数据的过程：
第一步：UE发送message 1，包括：
UE从小区配置的随机接入信道资源中随机选择一个前导序列(preamble)，并在随机接入信道上发送。
第二步：接入网网元接收到UE发送的message 1，回应message 2；
其中，所述Message 2又称为随机接入响应(RAR，Random Access Response)消息，RAR消息中携带了针对UE发送的preamble的回应信息，包括发送message 3的资源的上行授权(UL grant)，以及一个临时的RNTI(temp C-RNTI)，以及上行定时调整的信息(timing advance command)。
第三步：UE发送message 3；
如果UE接收到针对它在message 1所发送的premable的RAR回应信息，则根据定时调整信息调整发送上行信号的定时偏移，以及在所述的上行授权的资源中发送message 3。
所述的message 3的内容包括：
UE的标识以及，UE的上行数据；UE的标识表现为在UE Context ID，或其它在接入网的RNA内可以唯一标识该UE的标识，或其它在一个小区内可以唯一标识该UE的标识。
在一实施例中，所述的message 3的内容还包括：UE的认证信息，例如short MAC-I。
在一实施例中，所述的message 3的内容还包括：UE发起上行数据传输的原因信息(cause)。
在一实施例中，所述的message 3的内容还包括：UE上行数据缓冲区的信息(BSR，Buffer Status Report)。
第四步：接入网网元回应message 4；
这里，针对接收到的message 3，网络侧通过temp C-RNTI加扰的PDCCH信令调度发送message 4的信道资源，UE通过检测在message 2中接收到的temp C-RNTI得到message 4的调度信息从而接收messag 4。
所述Message 4中包括contention resolution MAC CE，该MAC CE中包含用于UE竞争解决的标识，接收到message 4的UE检查该UE竞争解决标识是否为自己的竞争解决标识，如果是，则UE此次的RACH过程成功结束，否则此次RACH过程的竞争解决失败。
在相关技术中，message 4还将承载一个RRC消息以更新UE的AS配置、指示UE的后续RRC状态、以及提供接入网网元的认证信息。
关于图13所示的流程与图12所示的流程类似，在图13的第一步UE发送给接入网网元的message 1中的信息为图12中message 1与message3中信息的叠加；在图13的第二步接入网网元发送给UE的message 2中的信息为图12中message 4中信息的相似，此处不再详细描述。
从上文描述可知，如果UE发起上行数据发送的小区所在的服务网元不同于UE的anchor网元时，如实施例1所述，服务网元和UE的anchor网元之间需要一系列的交互，才能确定UE后续的RRC状态和行为。另一方面，UE需要确认服务网元不是一个假冒的接入网网元，因此需要对接入网网元进行认证，即提供接入网网元认证信息，而生成接入网网元认证信息的秘钥也需要从anchor网元传递到服务网元。
而考虑到服务网元和anchor网元之间的交互存在延时，例如在相关技术中，二者之间的单向的通信延时可能最大达到100毫秒(ms)，则来回多次的延时最大可到几百毫秒。
如果服务网元和anchor网元间结束交互过程才能发送message 4，UE需要在这最大几百毫秒的时间内保持监听下行控制信道，这白白消耗了UE的电池。
更不利的是，UE在这段时间内并不能判断其RACH过程是否成功，还是竞争解决失败。因此，如果UE在这次RACH过程中竞争解决已经失败(接入网没有成功解码该UE发送的message 3)，UE也不能继续发起新的RACH过程，从而增加该UE发送上行数据的延时。
针对上述的问题，本实施例提供了下面的方法(结合图11和图14所示，下面描述以四步RACH过程为例)：
接收到message 3的接入网网元，通过message 4发送竞争解决的MAC CE(UE contention Resolution MAC CE)，并在message 4中携带UE监听下行控制信道的时间信息。
接收到message 4的UE，如果确定message 4携带的竞争解决标识为该UE的竞争解决标识，则该UE根据上述的监听下行控制信道的时间信息，来监听下行控制信道。
上述在message 4中指示的UE监听下行控制信道的时间信息可包括如下方式中的一种：
一个时间偏移信息；即UE从接收到该信息的时间加上所述时间偏移的时间开始监听下行控制信道；
一个时间偏移信息和一个时间长度信息；即：UE从接收到该信息的时间加上所述时间偏移的时间开始，在所述时间长度的时间内监听下行控制信道。在时间偏移信息缺省时，所述的时间偏移值为0；
一个DRX配置信息，包括DRX周期，以及在一个DRX周期内监听下行控制信道的时间段信息(时间偏移，和/或，时间长度)。UE在每个DRX配置信息指示的监听下行控制信道的时间段内监听下行控制信道。DRX配 置信息还可以包括该DRX有效的时间范围信息、或有效的DRX重复次数信息。
服务网元在message 4之后的调度发送携带有指示UE的后续RRC状态转换、以及接入网网元认证信息的RRC消息或MAC CE。
例如，按照实施例1的方法，服务网元在接收到UE的anchor网元发送的获取UE上行文回应消息后，发送上述的RRC消息或MAC CE。
由于上述服务网元和anchor网元之间的延时是相对确定的，服务网元可以根据与anchor网元之间的通信历史可以知道，从而服务网元可以在上述message 4中恰当的设置UE监听下行控制信道的时间。
图15说明了基于两步RACH的过程中，如何实施本实施例提供的方法。下面简单描述如下：
接收到message 1的接入网网元，通过message 2发送竞争解决的MAC CE(UE contention Resolution MAC CE)，并在message 2中携带UE监听下行控制信道的时间信息。所述UE监听下行控制信道的时间信息的内容与上文描述相同，不再描述。
接收到message 2的UE，如果确定message 2携带的竞争解决标识为该UE的竞争解决标识，则该UE根据上述的监听下行控制信道的时间信息，来监听下行控制信道。
可见，本实施例本质上是将回应UE发送的RRC消息(例如RRC resume request)的回应消息(例如RRC resume)与message 4(message 2)解除了绑定关系。在上述的场景下，服务网元可以在最短的时间内发送messag 4(message 2)指示UE竞争解决标识，而不需要等待服务网元与anchor网元间的交互结束后和回应UE的RRC消息一起发送；从而竞争解决失败的UE可以尽快的重新发起RACH过程，而竞争解决成功的UE则根据本实施例提供的方法，即message 4(message 2)中指示的监听下行控制信道的时 间信息，来在合适的时间窗内开始监听下行控制信道，从而节省了UE的电池消耗。
当然，本实施例方法同样适用于在非活动状态下发送下行数据过程中，在发送给UE的任何一个下行MAC CE中指示UE在接收到该MAC CE之后监听下行控制信道的时间。

工业实用性
本发明实施例通过将UE状态指示信息发送给第二接入网网元，服务网元依据所述UE状态指示信息便可在路径切换完成前确定UE的状态，并转换UE的状态。例如：如果没有缓冲的下行数据和上行数据，服务网元可以尽快发送消息指示UE保持在inactive状态并停止监听下行控制信道，这样可以减少UE监听下行控制信道的时间，从而节省UE的电能消耗。另外，通过将UE监听下行控制信道的时间信息发送给UE，而不需要等待服务网元与锚点网元间的交互结束后和回应UE的RRC消息一起发送，从而竞争解决失败的UE可以尽快的重新发起RACH过程，而竞争解决成功的UE则根据所述UE监听下行控制信道的时间信息监听下行控制信道，从而节省了UE的电池消耗。
