Description

链路恢复方法、装置、设备及处存储介质 技术领域
本公开涉及通信技术领域，具体而言，本公开涉及一种链路恢复方法、装置、设备及处存储介质。
背景技术
为了扩展网络覆盖，当UE(User Equipment，用户设备)在小区内信号不佳时可以考虑连接到中继UE(relay UE)，以接续在当前小区的连接与数据传递。中继UE本身是具有中继功能的终端。经过中继UE连接到网络的UE本身为远端UE(remote UE)。
对于UE-to-network relay(即U2N relay)，中继UE和远端UE之间使用sidelink(边缘链路)直接通信接口，中继UE与网络/基站之间使用Uu link(空口链路)。R17的sidelink仅允许远端UE通过单个中继UE的单链路连接接入到网络侧。R18引入了多路径场景，即远端UE可以通过一个至多个中继UE以及一个直连Uu link接入网络侧，用以提升remote UE接入网络的可靠性以及峰值速率。R18目前仅允许多路径接入同一个基站，后续可能允许多路径接入不同的基站也即多连接，即可实现多路径(multi-path)/多连接(multi-connection)的场景。
由于多路径/多连接的场景涉及sidelink直接通信接口和Uu口，当前的链路恢复方案无法实现该场景下链路的快速恢复，限制了峰值速率，因此有必要提供一种针对多路径/多连接场景的快速链路恢复方案。

在本公开的一种可选实施例中，该方法还包括：在处于非连接态之前，接收网络侧发送的SL-EMR测量配置信息；在处于非连接态时，获取SL-EMR测量结果，包括：在处于非连接态时，基于SL-EMR测量配置信息获取SL-EMR测量结果。

具体实施方式
下面详细描述本公开的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本公开，而不能解释为对本公开的限制。
本技术领域技术人员可以理解，除非特意声明，这里使用的单数形式“一”、“一个”、“所述”和“该”也可包括复数形式。应该进一步理解的是，本公开的说明书中使用的措辞“包括”是指存在所述特征、整数、步骤、操作、元件和/或组件，但是并不排除存在或添加一个或多个其他特征、整数、步骤、操作、元件、组件和/或它们的组。应该理解，当我们称元件被“连接”或“耦接”到另一元件时，它可以直接连接或耦接到其他元件，或者也可以存在中间元件。此外，这里使用的“连接”或“耦接”可以包括无线连接或无线耦接。这里使用的措辞“和/或”包括一个或更多个相关联的列出项的全部或任一单元和全部组合。
为使本公开的目的、技术方案和优点更加清楚，下面将结合附图对本公开实施方式作进一步地详细描述。
对于仅涉及Uu口的链路，可以采用基于提早测量上报(early measurement report，EMR)的方式实现链路快速恢复。在一个LTE/NR双 连接架构的示例中，可能有一个MN(Master Node，主节点)，以及一至多个SN(Secondary Node，辅助节点)。MN与SN节点均为基站节点，可以使用LTE/e-LTE/NR等技术。当前针对Uu口的EMR流程，为MN释放UE连接时，在RRC释放消息中携带EMR相关的配置信息，包括：载波信息、区域范围、以及定时器等内容。当然，也可以在系统信息中携带EMR相关配置信息。如图1所示，针对Uu口的EMR流程可以包括一下几个步骤：
1、MN与SN协商UE的测量配置过程，该步骤可选，MN可以直接决定给UE下发哪些提早测量配置信息；
2、MN确定是否给UE下发提早测量配置；
3、当网络侧给UE下发连接释放消息时，可以携带EMR配置信息；
4、UE收到后，进入IDLE(空闲模式)/INACTIVE(去激活模式)态后收集相关测量结果；
5、当UE建立/恢复连接时，在RRC建立/恢复完成消息中携带EMR可用指示信息；
6、如果网络想要获得EMR测量结果，则请求UE上报。UE将之前收集的IDLE/INACTIVE态EMR测量结果上报给网络侧；
7、网络侧可以根据收集到的测量结果给UE配置双连接。基于UE上报的EMR测量结果内容，新配置的SN可以与UE连接释放在前的SN相同或不同。
如果没有上述针对Uu口的EMR提早测量与上报机制，当UE建立/恢复RRC连接后，需要网络侧重新给UE配置测量，然后UE经过测量评估后再上报给网络侧，进而网络才能给UE配置合适的双连接。使用上述针对Uu口的EMR方式后，节省了UE进入连接态后重新接收测量配置与执行测量与评估的时间，使得网络可以尽快为UE执行双连接配置，恢复/建立双连接，快速提升峰值速率。
但是，当前仅有针对Uu口的EMR方式与配置参数，但针对sidelink的PC5接口，尚未有相关的EMR方式及配置参数。因此，由于多路径/多连接的场景涉及sidelink直接通信接口和Uu口，当前的链路恢复方案 无法实现该场景下链路的快速恢复。
本公开提供的链路恢复方法、装置、设备及处存储介质，旨在解决现有技术的如上技术问题。
下面以具体地实施例对本公开的技术方案以及本公开的技术方案如何解决上述技术问题进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。下面将结合附图，对本公开的实施例进行描述。
图2为本公开实施例提供的一种链路恢复方法的流程示意图，该方案应用于用户设备UE侧，如图2所示，该方法可以包括：
步骤S201，在处于非连接态时，获取边缘链路提早测量上报SL-EMR测量结果；步骤S202，在进入连接态时，将SL-EMR测量结果发送至对应的网络侧，以进行链路恢复。
具体地，在UE处于非连接态时，UE基于接收到的SL-EMR测量指示，执行对SL(sideline)相关节点的EMR测量，获得相应的SL-EMR测量结果。在UE进入连接态时，将该SL-EMR测量结果发送至对应的网络侧。网络侧基于接收到的SL-EMR测量结果进行分析判断，以实现UE和相应网络侧的连接恢复。
本公开实施例提供的方案，UE在处于非连接态时获取了SL-EMR测量结果，并在进入连接态时将SL-EMR测量结果上报至相应的网络侧，使得UE在需要与相应的网络侧进行链接恢复前，无需进行SL相关节点的EMR测量，节省了UE进入连接态后重新获取SL-EMR测量结果的时间，进而能够实现多路径/多连接场景下的链路快速恢复。
在本公开的一种可选实施例中，该方法还可以包括：
接收网络侧基于SL-EMR测量结果发送的多路径链路配置信息，并基于多路径链路配置信息进行链路恢复。
具体地，在UE将获得的SL-EMR测量结果发送至对应的网络侧后，网络侧基于SL-EMR测量结果的内容确定是否给UE配置多路径/多连接。如果确定需要配置多路径/多连接，则网络侧会基于接收到的SL-EMR测量结果生成相应的多路径链路配置信息，并将该多路径链路配置信息反馈 至UE，UE接收到该多路径链路配置信息后，将基于该多路径链路配置信息进行链路恢复。
本公开方案中，UE获取SL-EMR测量结果可以基于两种方式，其一为基于网络侧下发的SL-EMR测量配置信息获取SL-EMR测量结果，其二是基于网络侧下发的中继发现(relay discovery)指示。下面将对这两种方式进行详细说明。
在本公开的一种可选实施例中，该方法还可以包括：
在处于非连接态之前，接收网络侧发送的SL-EMR测量配置信息；
在处于非连接态时，获取SL-EMR测量结果，包括：
在处于非连接态时，基于SL-EMR测量配置信息获取SL-EMR测量结果。
具体地，UE在处于非连接态之前，接收网络侧发送的SL-EMR测量配置信息，并在处于连接态时，基于接收到的SL-EMR测量配置信息进行SL相关节点的EMR测量，得到SL-EMR测量结果。
在本公开的一种可选实施例中，SL-EMR测量配置信息可以包括以下各项中的一项或多项：
SL-EMR测量对象信息；
SL-EMR报告配置信息；
SL-EMR测量时间定时器长度信息和测量间隔信息；
SL-EMR测量区域范围信息；
测量所在部分带宽BWP的子载波间隔。
具体地，SL-EMR测量对象信息可以进一步包括：传输资源池相关信息，频点信息，参考符号信息，信道配置信息，测量带宽信息等。
SL-EMR报告配置信息可以进一步包括：测量触发事件配置，相关门限信息(例如测量评估门限值，可以为SL-RSRP，SD-RSRP以及SL-U测量量中的任何一种的门限值)，测量记录周期，记录次数等。
SL-EMR测量区域范围信息可以进一步包括：小区级区域信息，TA级区域信息，频点级区域信息或PLMN列表。
在本公开的一种可选实施例中，SL-EMR测量对象信息包含有至少一 个预设中继UE的标识信息，预设中继UE的标识信息所指示的中继UE被优先测量。
具体地，预设中继UE可以为在UE处于非连接态之前，与UE连接的一个或多个中继UE。UE在执行EMR测量时，将优先对这些预设中继UE进行测量。
需要说明的是，本公开实施例中所说的链路恢复，可以是基于SL-EMR测量结果，恢复UE与之前连接的中继UE的链路，也可以是基于SL-EMR测量结果，恢复UE与一个新的中继UE之间的链路。换言之，恢复后的链路与之前的链路相应的中继节点可以相同也可以不相同。
在本公开的一种可选实施例中，在处于非连接态时，基于SL-EMR测量配置信息获取SL-EMR测量结果，包括：
若SL-EMR测量配置信息中包含SL-EMR测量时间定时器长度信息，则在SL-EMR测量时间定时器超时前，基于SL-EMR测量配置信息获取SL-EMR测量结果；
若SL-EMR测量配置信息中不包含SL-EMR测量时间定时器长度信息，则一直基于SL-EMR测量配置信息获取SL-EMR测量结果，或者在空口链路提早测量上报Uu-EMR测量时间定时器超时前，基于SL-EMR测量配置信息获取SL-EMR测量结果。
具体地，如果SL-EMR测量配置信息中包含SL-EMR测量时间定时器长度信息，说明网络侧为UE单独配置了SL-EMR测量时间定时器，那么UE针对中继的EMR测量在该定时器超时前执行，即基于SL-EMR测量配置信息获取SL-EMR测量结果，且在该定时器超时后是否继续执行取决于UE实现。如果SL-EMR测量配置信息中不包含SL-EMR测量时间定时器长度信息，说明网络侧没有为UE单独配置了SL-EMR测量时间定时器。那么，UE针对中继的EMR测量在原有针对Uu口配置的EMR定时器(即Uu-EMR测量时间定时器)超时前执行，基于SL-EMR测量配置信息获取SL-EMR测量结果，且在该定时器超时后是否继续执行取决于UE实现；或者，UE一直基于SL-EMR测量配置信息获取SL-EMR测量结果。
需要说明的是，SL-EMR配置信息中除了包含SL-EMR配置参数还可以包含有Uu-EMR配置参数，基于Uu-EMR配置参数进行针对Uu口的EMR测量的过程在此不在赘述。
可以理解的是，如果UE收到针对中继的EMR配置，仅针对中继执行EMR测量与记录。如果UE同时收到针对小区/基站与中继的EMR配置，针对小区/基站与中继均进行EMR测量与记录。
在本公开的一种可选实施例中，该方法还可以包括：
在处于非连接态之前，接收网络侧发送的中继发现指令；
在处于非连接态时，获取SL-EMR测量结果，包括：
在处于非连接态时，执行中继发现指令并对发现的中继UE进行测量，并将测量结果作为SL-EMR测量结果。
具体地，UE在处于非连接态之前，接收网络侧发送的中继发现指令，并在处于连接态时，执行中继发现指令并对发现的中继UE进行测量，并将测量结果作为SL-EMR测量结果。该方式省去了网络侧进行SL-EMR测量配置信息配置的工作量，简化了链路恢复过程中网络侧的工作。
在本公开的一种可选实施例中，在进入连接态时，将SL-EMR测量结果发送至对应的网络侧，包括：
在进入连接态时，将SL-EMR测量结果携带于无线资源控制RRC建立/恢复完成消息中发送至对应的网络侧；或，
在进入连接态时，将携带有SL-EMR测量结果指示信息的RRC建立/恢复完成消息发送至对应的网络侧，以供网络侧基于SL-EMR测量结果指示信息获取SL-EMR测量结果。
具体地，UE在获得了SL-EMR测量结果后，在进入连接态时可以有两种方式向网络侧上报SL-EMR测量结果。其一是，直接将SL-EMR测量结果携带于无线资源控制RRC建立/恢复完成消息中发送至对应的网络侧。其二是将携带有SL-EMR测量结果指示信息的RRC建立/恢复完成消息发送至对应的网络侧，即向网络侧发送SL-EMR测量结果可用指示(available indicator)，该可用指示可以复用现有的针对Uu口的EMR测量结果可用指示。然后网络侧再基于该可用指示向UE请求对应的 SL-EMR测量结果。
具体来说，UE向网络侧指示UE保存有SL-EMR测量结果，或者UE复用现有的针对Uu口的EMR测量结果可用指示；网络侧基于可用指示向UE请求SL单独的EMR测量结果，或者所有EMR测量结果；相应地，UE向网络侧上报SL单独的EMR测量结果，或者所有EMR测量结果。
在本公开的一种可选实施例中，该方法还可以包括：
若在将SL-EMR测量结果发送至对应的网络侧的过程中发生了切换或重建，则在接入新的小区时，在新的小区将SL-EMR测量结果重新发送至对应的网络侧。
具体地，如果UE保存有SL-EMR测量配置信息，但在接入连接态后尚未上报完成时发生了切换或者重建，当UE接入新小区时，可以在新小区重新上报。上报方式可以为：
在RRC重配/重建完成消息中直接携带测量结果；或者，
仅在RRC重配/重建完成消息中携带相关结果可用指示(available indicator)，然后在后续步骤中单独上报测量结果(例如网络侧收到可用指示后请求UE上报测量结果)。
如果使用发送可用指示后等待网络请求测量结果的方式，相关的方式或方式组合与前述实施例相同。
在本公开的一种可选实施例中，基于多路径链路配置信息进行链路恢复，包括：
与多路径链路配置信息所指示的中继UE建立PC5口连接。
具体地，UE接收到网络侧的多路径链路配置信息后，与多路径链路配置信息中指示的中继UE发起PC5口连接。该连接可以是由UE触发的，也可以是由中继UE触发的。
在本公开的一种可选实施例中，该方法还可以包括：
在处于非连接态之前，向网络侧发送支持SL-EMR测量指示信息。
具体地，为了使网络侧能够获知UE是否支持SL相关的提早测量以及记录/上报，或者与当前现有的Uu-EMR相区分，UE可以在AS能力上报中，上报是否支持SL-EMR。具体来说，若UE支持SL-EMR，则在处 于非连接态之前，向网络侧发送支持SL-EMR测量指示信息。
网络收到该UE能力指示后，可以确定该UE是否支持SL的EMR，从而确定是否给该UE下发SL相关的EMR配置信息。如果UE的Uu相关EMR与SL相关EMR使用共同的可用指示(available indicator)，该能力可以使网络确定从UE获取的EMR测量结果中是否包含SL-EMR测量结果，从而在向UE请求指示前评估UE上报信息的大小，确定获取EMR测量结果的合适时机。
图3为本公开实施例提供的一种链路恢复方法的流程示意图，应用于网络侧，如图3所示，该方法可以包括：
步骤S301，在UE进入连接态时，接收UE发送的边缘链路提早测量上报SL-EMR测量结果；步骤S302，若基于SL-EMR测量结果确定需要配置多路径链路，则基于SL-EMR测量结果确定相应的多路径链路配置信息，并将多路径链路配置信息发送至UE，以供UE基于多路径链路配置信息进行链路恢复。
其中，UE发送的SL-EMR测量结果是其在处于非连接态时，基于接收到的SL-EMR测量指示测量得到的。
本公开实施例提供的方案，UE在处于非连接态时获取了SL-EMR测量结果，并在进入连接态时将SL-EMR测量结果上报至相应的网络侧，使得UE在需要与相应的网络侧进行链接恢复前，无需进行SL相关节点的EMR测量，节省了UE进入连接态后重新获取SL-EMR测量结果的时间，进而能够实现多路径/多连接场景下的链路快速恢复。
由前文所述可知，本公开方案中，UE获取SL-EMR测量结果可以基于两种方式，其一为基于网络侧下发的SL-EMR测量配置信息获取SL-EMR测量结果，其二是基于网络侧下发的中继发现指示。因此在第一种方式中网络侧需要下发SL-EMR测量配置信息，在第二种方式中网络侧需要下发中继发现指示。下面将对两种方式中网络侧的下发过程进行详细说明。
在本公开的一种可选方式中，该方法还可以包括：
在处于非连接态之前，向UE发送SL-EMR测量配置信息，以供UE在处于非连接态时，基于SL-EMR测量配置信息获取SL-EMR测量结果。
具体地，向UE发送SL-EMR测量配置信息，包括：将SL-EMR测量配置信息携带于专用信令中发送至UE；和/或，将SL-EMR测量配置信息携带于系统信息中发送至UE。
其中，专用信令为无线资源控制RRC连接释放消息或RRC重配置消息。系统信息为与空口链路提早测量上报Uu-EMR测量共用的系统消息块SIB消息或单独给出的SIB消息。
在本公开的一种可选实施例中，SL-EMR测量配置信息通过以下方式获取：获取中继相关的测量配置；基于中继相关的测量配置和网络相关的测量配置，获取SL-EMR测量配置信息。
具体地，用于快速建立/恢复多路径/多连接的测量配置信息下发，可能允许NW节点与远端UE现有中继UE(即与UE连接的当前中继UE)之间进行协商，并最终由NW决定给UE下发的测量配置信息，并发送给UE；也可能NW自行决定给UE下发的测量配置信息，并直接发送给UE。而最终下发的测量配置信息可以由中继相关的测量配置和网络相关的测量配置整合得到。
在本公开的一种可选实施例中，获取中继相关的测量配置，包括以下各方式中的任一种方式：在UE进入非连接态之前，向与UE连接的当前中继UE发送第一测量配置请求，并接收当前中继UE响应于第一测量配置请求发送的当前中继UE所需测量的中继相关的测量配置；
在UE进入非连接态之前，向当前中继UE发送携带有网络相关的测量配置的第二测量配置请求，并接收当前中继UE响应于第二测量配置请求发送的与网络相关的测量配置互补的中继相关的测量配置；
在UE进入非连接态之前，接收当前中继UE发送的中继相关的测量配置。
具体地，NW决定释放与UE的RRC连接到IDLE或者到INACTIVE，并且想要给UE配置用于SL-EMR多路径/多连接的测量时，可以与UE的 当前中继UE进行SL-EMR测量配置信息的协商，该协商过程可以包括有以下三种方案：
方案1：可以由NW节点向当前中继UE发送测量配置请求(即第一测量配置请求)，当前中继UE将需要UE测量的内容反馈给NW节点；
方案2：可以由NW向当前中继UE发送携带推荐配置的请求(即第二测量配置请求)，当前中继UE基于NW已有的测量配置，将中继相关的补充/修正测量配置参数发送给NW。
方案3：当前中继UE直接向NW节点发送中继相关的测量配置。
在本公开的一种可选实施例中，若将SL-EMR测量配置信息携带于RRC连接释放消息中发送至UE，则基于中继相关的测量配置和网络相关的测量配置获取SL-EMR测量配置信息，包括：
将中继相关的测量配置与网络相关的测量配置整合到RRC连接释放消息中的一个单独的域中，得到SL-EMR测量配置信息；或者，
将中继相关的测量配置与网络相关的测量配置整合为同一套参数，得到SL-EMR测量配置信息。
具体地，在组装最终发送给UE的SL-EMR测量配置信息时，NW可以将中继相关的测量配置与NW相关的测量配置，一起配置在一条RRC连接释放消息中，并设置单独的域(field)独立携带(例如NW节点与relay节点为inter-RAT)，或者由NW节点进行决策/整合，仅设置一套给UE下发的最终参数。
可以理解的是，网络侧生成SL-EMR测量配置信息，并下发给UE进行相应的SL-EMR测量的过程如图4所示，可以包括以下几个步骤：
1、NW与当前中继UE协商下发给UE的测量配置(包括网络相关的测量配置和中继相关的测量配置)；
2、NW针对网络相关的测量配置和中继相关的测量配置进行决策/整合/组装，得到下发给UE的SL-EMR测量配置信息；
3、NW将得到的SL-EMR测量配置信息下发给UE；
4、UE在处于非连接态时，基于接收到的SL-EMR测量配置信息进行 测量。
在本公开的一种可选实施例中，该方法还可以包括：
在处于非连接态之前，向UE发送的中继发现指令，以供UE在处于非连接态时，执行中继发现指令并对发现的中继节点进行测量，并将测量结果作为SL-EMR测量结果。
具体地，向UE发送SL-EMR测量配置信息，包括：将中继发现指令携带于专用信令中发送至UE；和/或，将中继发现指令携带于系统信息中发送至UE。
其中，专用信令为无线资源控制RRC连接释放消息或RRC重配置消息。系统信息为与空口链路提早测量上报Uu-EMR测量共用的系统消息块SIB消息或单独给出的SIB消息。
下面通过一个示例来对本公开实施例提供的多路径/多连接场景下的链接恢复方法进行进一步说明，如图5所示，该方法可以包括以下几个步骤：
1、UE在IDLE/INACTIVE态执行基于网络配置的SL-EMR测量配置信息的测量，得到相应的SL-EMR测量结果；
2、UE与网络侧建立/恢复RRC连接，该步骤可能是由于网络侧寻呼了该UE而发起的，或者UE自行发起的连接建立/恢复；该步骤中，UE可能与NW之间建立直接连接；或者通过一至多个中继UE建立非直接连接，则NW与所连接的中继UE之间为Uu口连接，UE与中继UE之间以及可能的中继UE与中继UE之间为PC5口连接；
3、UE向网络侧上报SL-EMR测量结果；
4、与UE建立/恢复连接的网络侧节点接收到SL-EMR测量结果后，根据测量结果内容决定是否给UE配置多路径/多连接。如果确定需要配置，向相应的中继UE发送多路径链路配置信息，该信息中可能包括UE针对该中继的测量结果；
5、同时NW在RRC重配置消息中给UE下发多路径链路配置信息， 完成针对UE的配置；该步骤5与步骤4的顺序可变换；
6、UE接收到网络侧配置后，与配置中指示的中继UE发起PC5口连接。该连接可能是有UE触发的，或者由中继UE触发的。
