Description

用户设备的控制方法以及用户设备User equipment control method and user equipment 技术领域Technical field
本发明涉及无线通信技术领域，更具体地，本发明涉及用户设备的控制方法以及用户设备。The present invention relates to the field of wireless communication technology, and more specifically, the present invention relates to a control method of user equipment and user equipment.
背景技术Background technique
随着移动通信的快速增长和技术的巨大进步，世界将走向一个完全互联互通的网络社会，即任何人或任何东西在任何时间和任何地方都可以获得信息和共享数据。为了增强移动宽带业务需求、海量物联网终端的通信需求，新一代通信技术(5G)将研究用户在双连接以至多连接下的技术增强(RP-181469 New WID on DC and CA enhancements)。With the rapid growth of mobile communications and the tremendous advancement of technology, the world will move towards a completely interconnected network society, that is, anyone or anything can obtain information and share data at any time and anywhere. In order to enhance the demand for mobile broadband services and the communication needs of massive IoT terminals, the new generation of communication technology (5G) will study the technical enhancements (RP-181469 New WID on DC and CA enhancements) for users under dual connections and at most multiple connections.
双连接或者多连接，是指工作在连接态的UE与多于一个网络节点建立物理上的通路，并实现数据传输。其中，包括主控制节点(Master Node，MN)与辅助控制节点(Secondary Node，SN)。MN由一个Gnb/Enb/ng-eNB来执行，由MN控制的服务小区组称为主小区组(Master Cell Group，MCG)。相应地，SN由一个或多个Gnb/Enb/ng-eNB来执行，由SN控制的服务小区组称为辅小区组(Secondary Cell Group，SCG)。Dual connectivity or multiple connectivity means that a UE working in a connected state establishes a physical path with more than one network node and realizes data transmission. Among them, it includes a master control node (Master Node, MN) and a secondary control node (Secondary Node, SN). The MN is executed by a Gnb/Enb/ng-eNB, and the serving cell group controlled by the MN is called a master cell group (Master Cell Group, MCG). Correspondingly, the SN is executed by one or more Gnb/Enb/ng-eNBs, and the serving cell group controlled by the SN is called a secondary cell group (SCG).
被配置了双连接或者多连接的UE可以通过MCG或者SCG进行通信。在现有机制中，当MCG发生链路传输问题时，即使UE通过SCG也能够正常传输，UE还是需要触发RRC连接重建立过程，通过小区重选机制，选择合适的小区进行链路连接恢复，同时释放之前配置的SCG。重建过程需要持续一段时间，并且有可能失败，需要中断UE的传输，增加了业务传输时延。A UE configured with dual connectivity or multiple connectivity can communicate through MCG or SCG. In the existing mechanism, when the MCG has a link transmission problem, even if the UE can transmit normally through the SCG, the UE still needs to trigger the RRC connection re-establishment process, through the cell reselection mechanism, select the appropriate cell for link connection recovery, At the same time, the previously configured SCG is released. The reconstruction process needs to last for a period of time, and may fail, and the UE transmission needs to be interrupted, which increases the service transmission delay.
为了解决这一问题，现有机制中提出当MCG发生链路失败，如果SCG能够正常工作，那么UE可以通过SCG向网络侧报告MCG发生失败的信息，然后网络侧经由SCG向UE发送RRC重配置消息，通过重配置使得UE继续工作，从而将链路中断带来的影响降到最低。In order to solve this problem, the existing mechanism proposes that when the MCG has a link failure, if the SCG can work normally, the UE can report the failure of the MCG to the network side through the SCG, and then the network side sends the RRC reconfiguration to the UE via the SCG Message, through reconfiguration to enable the UE to continue to work, thereby minimizing the impact of link interruption.
在这一方案中，当UE向网络侧报告MCG发生失败的信息后，可以启动一个复原定时器，当这个复原定时器超时时，UE还没有接收到网络侧发送的任何响应信息，那么UE可以判定复原失败；类似地，当这个复原定时器在运行时，如果UE检测到了SCG传输发送失败，那么UE也可以判定复原失败。In this scheme, after the UE reports the failure of MCG to the network side, it can start a recovery timer. When the recovery timer expires, the UE has not received any response information sent by the network side, then the UE can It is determined that the restoration has failed; similarly, when the restoration timer is running, if the UE detects that the SCG transmission has failed, the UE can also determine that the restoration has failed.
在这两种情况下，UE只能触发RRC连接重建立过程，在这一过程中，UE向基站发送RRC连接重建请求消息，在该消息中携带了触发本次RRC连接重建的重建原因。那么对于判定复原失败而触发的RRC连接重建过程，如何设置这个重建原因以指明RRC连接重建的原因，是需要解决的问题。In these two cases, the UE can only trigger the RRC connection re-establishment process. In this process, the UE sends an RRC connection re-establishment request message to the base station, which carries the reason for triggering the re-establishment of the RRC connection. Then for the RRC connection re-establishment process triggered by the determination of the restoration failure, how to set the re-establishment reason to indicate the reason for the RRC connection re-establishment is a problem that needs to be solved.

下面，对本发明中的用户设备UE的控制方法进行说明，具体而言，对用户设备UE的接入控制方法进行说明。作为一例，图1中表示基于本发明的实施例的用户设备UE的控制方法100的流程图。In the following, the control method of the user equipment UE in the present invention will be described, specifically, the access control method of the user equipment UE will be described. As an example, FIG. 1 shows a flowchart of a method 100 for controlling a user equipment UE according to an embodiment of the present invention.
在步骤S101中，用户设备UE执行主小区组(Master Cell Group：MCG)失败复原操作In step S101, the user equipment UE performs a master cell group (Master Cell Group: MCG) failure recovery operation
在步骤S102中，用户设备UE对上述复原操作中是否发生失败进行检测。当用户设备UE在检测到MCG失败复原操作发生失败的情况下，进入步骤S103。In step S102, the user equipment UE detects whether a failure occurs in the aforementioned restoration operation. When the user equipment UE detects that the MCG failure recovery operation has failed, it proceeds to step S103.
在步骤S103中，用户设备触发RRC连接重建过程。在这一过程中，用户设备UE向基站发送RRC连接重建请求消息，在生成这条消息的过程中，用户设备UE需要设置RRC连接重建的原因。用户设备UE根据所述的MCG失败复原操作发生失败的情况，设置所述RRC连接重建请求消息中的重建原因，包括以下的至少一种操作：In step S103, the user equipment triggers the RRC connection re-establishment process. In this process, the user equipment UE sends an RRC connection reestablishment request message to the base station. In the process of generating this message, the user equipment UE needs to set the reason for the RRC connection reestablishment. The user equipment UE sets the reestablishment reason in the RRC connection reestablishment request message according to the failure of the MCG recovery operation, including at least one of the following operations:
当所述UE发生重配置失败，并触发所述MCG失败复原操作时，设置所述重建原因，指示发生了重配置失败；When a reconfiguration failure occurs in the UE and the MCG failure recovery operation is triggered, setting the reconfiguration reason to indicate that a reconfiguration failure has occurred;
当所述UE发生重配置同步失败，并触发所述MCG失败复原操作时，设置所述重建原因，指示发生了重配置同步失败；When the UE fails to reconfiguration synchronization and triggers the MCG failure recovery operation, setting the reconfiguration reason to indicate that reconfiguration synchronization failure has occurred;
当复原定时器正在运行时，所述UE检测到SCG传输发生失败，设置所述重建原因，指示发生了SCG失败；When the recovery timer is running, the UE detects that the SCG transmission has failed, and sets the re-establishment reason to indicate that an SCG failure has occurred;
当复原定时器运行超时时，设置所述重建原因，指示发生了复原失败。When the restoration timer runs overtime, the reason for the restoration is set to indicate that restoration failure has occurred.
此外，图2中表示基于本发明的实施例的用户设备UE的控制方法200的流程图。In addition, FIG. 2 shows a flowchart of a method 200 for controlling a user equipment UE based on an embodiment of the present invention.
用户设备UE的控制方法200与上述控制方法100的不同点在于由步骤S201替换了步骤S101，其他的步骤与上述控制方法100相同。下面，仅对不同的部分进行详细说明，对于相同的部分，则省略说明。The control method 200 of the user equipment UE is different from the aforementioned control method 100 in that step S201 is replaced by step S101, and the other steps are the same as the aforementioned control method 100. Hereinafter, only the different parts will be described in detail, and the description of the same parts will be omitted.
在步骤S201中用户设备UE基于主小区组(Master Cell Group：MCG)、辅小区组(Secondary Cell Group：SCG)与基站进行通信；其中，所述UE对所述MCG传输中是否发生失败进行检测；在检测到所述MCG传输中发生了失败的情况下，所述UE启动或者触发向基站发送携带MCG失败相关信息的消息，并启动复原定时器。In step S201, the user equipment UE communicates with the base station based on the primary cell group (Master Cell Group: MCG) and the secondary cell group (Secondary Cell Group: SCG); wherein, the UE detects whether a failure occurs in the MCG transmission ; In the case of detecting a failure in the MCG transmission, the UE starts or triggers to send a message carrying MCG failure related information to the base station, and starts a recovery timer.
再有，对用户设备UE如何检测到上述复原操作中发生失败的控制方法进行说明：Furthermore, the control method for how the user equipment UE detects the failure in the above restoration operation is described:
当复原定时器运行超时的时候，用户设备UE判定检测到MCG失败复原操作发生了失败；或When the recovery timer runs out, the user equipment UE determines that the MCG failure recovery operation has failed; or
当复原定时器正在运行时，用户设备UE检测到所述SCG传输发生失败时，那么用户设备UE判定检测到所述MCG失败复原操作发生了失败。When the recovery timer is running and the user equipment UE detects that the SCG transmission fails, the user equipment UE determines that the MCG failure recovery operation has failed.
另外，用户设备UE在步骤201中向基站发送携带MCG失败相关信息的消息，这个消息中可以包含指示MCG失败的失败类型。UE可以设置所述RRC连接重建请求消息中的重建原因与这个MCG失败类型相同，或者相关联。因此，用户设备UE根据MCG失败复原操作发生失败，设置RRC连接重建请求消息中的重建原因的方法还可以包括：基于所述MCG失败类型，设置所述RRC连接重建请求消息中的重建原因。In addition, the user equipment UE sends a message carrying MCG failure related information to the base station in step 201, and this message may include a failure type indicating MCG failure. The UE may set the re-establishment reason in the RRC connection re-establishment request message to be the same as the MCG failure type, or be associated. Therefore, the user equipment UE fails according to the MCG failure recovery operation, and the method of setting the reestablishment reason in the RRC connection reestablishment request message may further include: setting the reestablishment reason in the RRC connection reestablishment request message based on the MCG failure type.
以下，对本发明所涉及的具体实施例进行详细说明。另外，如上所述， 本发明中的实施例是为了容易理解本发明而进行的示例性说明，并不是对本发明的限定。Hereinafter, specific embodiments related to the present invention will be described in detail. In addition, as described above, the embodiments of the present invention are illustrative descriptions for easy understanding of the present invention, and do not limit the present invention.
【实施例1】[Example 1]
步骤一：UE执行MCG失败复原相关的操作；Step 1: The UE executes operations related to MCG failure recovery;
这一步骤可以包含：This step can include:
UE工作在双连接(Dual Connectivity)的工作模式。在该工作模式下，UE通过主小区组(Master Cell Group：MCG)、辅小区组(Secondary Cell Group：SCG)与基站进行通信。The UE works in a dual connectivity (Dual Connectivity) working mode. In this working mode, the UE communicates with the base station through a primary cell group (Master Cell Group: MCG) and a secondary cell group (Secondary Cell Group: SCG).
在与基站通信期间，UE对MCG传输中是否发生失败(简称MCG失败)进行检测。当UE检测到MCG传输中发生了失败的情况下，UE可以向基站发送携带MCG失败相关信息的消息，这样的操作可以被称为MCG失败恢复/报告过程(MCG failure recovery/report procedure)，即，在UE检测到MCG传输中发生失败的情况下，UE触发或者启动MCG失败复原(MCG failure recovery)/报告(MCG failure report)过程。优选的，在启动(initiation)/触发(trigger)这一过程时，UE同时启动复原定时器。这个复原定时器还可以是UE在生成或者发送携带MCG失败相关信息的消息时启动的。During communication with the base station, the UE detects whether a failure occurs in MCG transmission (MCG failure for short). When the UE detects that a failure has occurred in the MCG transmission, the UE can send a message carrying information about the MCG failure to the base station. This operation can be called the MCG failure recovery/report procedure (MCG failure recovery/report procedure), namely In the case that the UE detects a failure in MCG transmission, the UE triggers or initiates the MCG failure recovery (MCG failure recovery)/report (MCG failure report) process. Preferably, when the process of initiation/trigger is initiated, the UE simultaneously starts the restoration timer. This recovery timer can also be started when the UE generates or sends a message carrying information about MCG failure.
作为补充，这样的检测不是一次性的，而是持续发生的。如果UE没有检测到上述失败的发生，UE可以根据其他的输入，例如链路质量的测量结果持续进行检测；还可以是UE持续等待，直到有失败情况的发生。As a supplement, such detection is not a one-time, but a continuous occurrence. If the UE does not detect the occurrence of the above-mentioned failure, the UE may continue to perform detection according to other inputs, such as the measurement result of the link quality; or the UE may continue to wait until a failure occurs.
在UE发送给基站的、携带MCG失败相关信息的消息中，可以携带在何种情况下检测到MCG失败，即MCG失败的类型。例如，当UE检测到MCG发生了下述的至少一种失败情况时，可以判定检测到MCG传输中发生了失败：The message carrying the MCG failure related information sent by the UE to the base station may carry the circumstances under which the MCG failure is detected, that is, the type of the MCG failure. For example, when the UE detects that at least one of the following failures has occurred in the MCG, it can determine that a failure has occurred in the MCG transmission:
-MCG无线链路失败；-MCG wireless link failure;
-MCG的下层，例如PDCP层，指示完整性保护校验失败；-The lower layer of MCG, such as the PDCP layer, indicates that the integrity protection check fails;
-MCG的RLC指示达到了最大允许的发送次数或者重传输次数；-MCG’s RLC indication has reached the maximum allowable number of transmissions or retransmissions;
-MCG MAC报告随机接入问题；-MCG MAC reports random access problems;
-UE接收到指示UE同步到目标小区的重配置消息，但是在定时器 T304运行超时，意味着UE同步到目标小区发生失败，这里简称为同步重配置失败；-The UE receives a reconfiguration message indicating that the UE synchronizes to the target cell, but the timer T304 runs out, which means that the UE fails to synchronize to the target cell, which is referred to as synchronization reconfiguration failure;
-UE接收到对UE进行重配置的重配置消息，但是UE不能遵从(comply)这样的配置，可能是配置的内容得不到UE能力的支持，这里简称为重配置失败；-The UE receives a reconfiguration message for reconfiguration of the UE, but the UE cannot comply with such a configuration. It may be that the content of the configuration is not supported by the UE's capabilities, which is referred to as reconfiguration failure here;
因此在生成的、携带MCG失败相关信息的消息中，可以携带信息指示上述任一失败情况的信息。通常，可以定义一个信元(Information Element)，可以称为失败类型(failure type)，UE用这个信元来向基站指示或者通知在何种情况下发生MCG失败，或者说是MCG失败的类型是哪一类。具体的失败类型可以与上述用于检测MCG发生失败的各种情况一一对应。这种用于判定MCG失败的情况还可以被称为MCG失败的原因，或者是触发MCG失败复原/报告过程的原因。Therefore, in the generated message carrying the MCG failure-related information, information indicating any of the above-mentioned failure conditions can be carried. Generally, an information element (Information Element) can be defined, which can be called a failure type. The UE uses this information element to indicate or notify the base station under which circumstances MCG failure occurs, or the type of MCG failure is Which kind. The specific failure types can correspond one-to-one with the various situations described above for detecting MCG failure. This situation used to determine MCG failure may also be referred to as the cause of MCG failure, or the cause of triggering the MCG failure recovery/reporting process.
例如，UE接收到指示UE同步到目标小区的重配置消息，但是没有成功同步到目标小区(例如，T304超时)。基于这一情况，UE检测到MCG传输发生了失败，因此生成携带MCG失败相关信息的消息。For example, the UE receives a reconfiguration message indicating that the UE synchronizes to the target cell, but fails to successfully synchronize to the target cell (for example, T304 timeout). Based on this situation, the UE detects that the MCG transmission has failed, and therefore generates a message carrying information about the MCG failure.
在该消息中，携带失败类型信元，该失败类型的内容可以是切换失败(或者称为同步重配置失败)，指示的是或者对应的是当UE接收到指示UE同步到目标小区的重配置消息，但是发生失败的的情况。这样一个内容为同步重配置失败的失败类型，还可以指示触发MCG失败报告/复原过程的原因是UE接收到指示UE同步到目标小区的重配置消息，但是发生失败。The message carries the failure type information element. The content of the failure type can be handover failure (or called synchronization reconfiguration failure), indicating or corresponding to when the UE receives the reconfiguration indicating that the UE synchronizes to the target cell Message, but a failure occurred. Such a content is the failure type of synchronization reconfiguration failure, and it can also indicate that the reason for triggering the MCG failure report/recovery process is that the UE received the reconfiguration message indicating that the UE synchronizes to the target cell, but failed.
又例如，UE接收到对UE进行重配置的重配置消息，但是UE不能够遵从(comply)这样的配置，因此基于这一情况，UE检测到MCG传输发生了失败，因此生成携带MCG失败相关信息的消息，在该消息中，携带失败类型，该失败类型的内容可以是重配置失败，指示的是或者对应的是当UE接收到对UE进行重配置的重配置消息，但是UE不能遵从(comply)这样的配置的情况。这样一个内容为重配置失败的失败类型，还可以指示触发MCG失败报告/复原过程的原因是UE不能够遵从其所接收到重配置消息。For another example, the UE receives a reconfiguration message for reconfiguring the UE, but the UE cannot comply with such a configuration. Therefore, based on this situation, the UE detects that the MCG transmission has failed, and therefore generates information that carries MCG failure related information. The message contains the failure type. The content of the failure type can be a reconfiguration failure. It indicates or corresponds to when the UE receives a reconfiguration message for reconfiguration of the UE, but the UE cannot comply with (comply ) In the case of such a configuration. Such a content is a failure type of reconfiguration failure, and it can also indicate that the reason for triggering the MCG failure report/recovery process is that the UE cannot comply with the reconfiguration message it receives.
又例如，MCG发生无线链路失败，基于这一情况，UE检测到MCG传输发生了失败，因此生成报告MCG失败相关信息的消息，在该消息中， 携带失败类型，该失败类型的内容可以是MCG无线链路失败，指示的是或者对应的是UE发生了MCG无线链路失败这样的失败情况。由于UE基于定时器T310的超时可以判定MCG无线链路失败，因此，这个失败类型还可以是T310超时。这样的类型就对应了UE发生了MCG无线链路失败这样的失败情况。这样一个内容为MCG无线链路失败的失败类型，还可以指示触发MCG失败报告/复原过程的原因是UE发生了MCG无线链路失败。For another example, MCG has a radio link failure. Based on this situation, the UE detects that MCG transmission has failed, and therefore generates a message reporting MCG failure related information. The message carries the failure type, and the content of the failure type may be The MCG radio link failure indicates or corresponds to the failure of the MCG radio link failure in the UE. Since the UE can determine that the MCG radio link fails based on the timeout of the timer T310, the failure type may also be T310 timeout. This type corresponds to the failure of the MCG radio link failure of the UE. Such a content is the failure type of the MCG radio link failure, and it can also indicate that the reason for triggering the MCG failure report/recovery process is that the UE has an MCG radio link failure.
又例如，MCG MAC报告随机接入问题，基于这一情况，UE检测到MCG传输发生了失败，因此生成报告MCG失败相关信息的消息，在该消息中，携带失败类型，该失败类型的内容可以是MCG MAC报告随机接入问题，指示的是或者对应的是UE发生了MCG MAC报告随机接入问题这样的失败情况。这样一个内容为MCG MAC报告随机接入问题的失败类型，还可以指示触发MCG失败报告/复原过程的原因是UE发生了MCG MAC报告随机接入问题。For another example, MCG MAC reports a random access problem. Based on this situation, the UE detects that MCG transmission has failed, and therefore generates a message reporting MCG failure related information. The message carries the failure type. The content of the failure type can be It is the MCG MAC reporting the random access problem, which indicates or corresponds to the failure of the MCG MAC reporting random access problem of the UE. Such a content is the failure type of the MCG MAC reporting random access problem, and it can also indicate that the reason for triggering the MCG failure reporting/recovery process is that the UE has the MCG MAC reporting random access problem.
步骤二：UE在执行步骤一所述的复原/报告操作的过程中，检测到复原过程发生了失败。一种可能的实现方式可以是UE在下述任一情况下，检测到复原过程发生了失败：Step 2: In the process of performing the restoration/reporting operation described in step 1, the UE detects that the restoration process has failed. A possible implementation may be that the UE detects that the restoration process has failed in any of the following situations:
-当复原定时器运行超时的时候，用户设备UE判定检测到所述MCG失败复原操作发生了失败；或-When the recovery timer runs out, the user equipment UE determines that the MCG failure recovery operation has failed; or
-当复原定时器正在运行时，用户设备UE检测到SCG传输发生失败时，那么用户设备UE判定检测到所述MCG失败复原操作发生了失败；或-When the recovery timer is running and the user equipment UE detects that the SCG transmission fails, the user equipment UE determines that the MCG failure recovery operation has failed; or
-当UE触发/启动MCG失败报告/复原过程，如果在这一过程中UE检测到SCG传输发生失败时，那么用户设备UE判定检测到所述MCG失败复原操作发生了失败。-When the UE triggers/starts the MCG failure report/recovery process, if the UE detects that the SCG transmission fails during this process, the user equipment UE determines that the MCG failure recovery operation has failed.
其中，UE检测到SCG发生了下述至少一种的失败情况时，判定检测到MCG失败复原操作发生了失败：Wherein, when the UE detects that the SCG has failed at least one of the following, it is determined that the MCG failure recovery operation has failed:
-SCG无线链路失败；-SCG wireless link fails;
-SCG的底层指示完整性保护校验失败；-The bottom layer of SCG indicates that the integrity protection verification failed;
-SCG的RLC指示达到了最大允许的发送次数或则重传输次数；-SCG’s RLC indication has reached the maximum allowable number of transmissions or retransmissions;
-SCG MAC指示随机接入问题。-SCG MAC indicates random access problems.
作为补充，对上述复原过程进行是否发生失败的检测不是一次性的，而是持续发生的。如果UE没有检测到上述失败的发生，UE可以根据其他的输入，例如链路质量的测量结果持续进行检测；还可以是UE持续等待，直到有失败情况的发生。As a supplement, the detection of failure in the above recovery process is not a one-time, but a continuous occurrence. If the UE does not detect the occurrence of the above-mentioned failure, the UE can continue to perform detection according to other inputs, such as the measurement result of the link quality; or the UE can continue to wait until a failure occurs.
步骤三：基于步骤二中的检测的结果，当UE检测到步骤一中的MCG失败复原操作发生了失败时，触发/启动RRC连接重建(RRC connection re-establishment)过程。在这一过程中，UE向基站发送RRC连接重建请求消息(RRCReestablishmentRequest message)。在这条消息中，UE设置RRC连接重建的重建原因(reestablishmen cause)的内容。设置的方法可以包括：Step 3: Based on the detection result in Step 2, when the UE detects that the MCG failure recovery operation in Step 1 has failed, it triggers/starts an RRC connection re-establishment (RRC connection re-establishment) process. In this process, the UE sends an RRC connection reestablishment request message (RRC Reestablishment Request message) to the base station. In this message, the UE sets the reestablishment cause of the RRC connection reestablishment. The setting method can include:
当UE发生了步骤一中描述的重配置失败，并触发MCG失败报告/复原过程时，设置重建原因，使其内容指示UE发生了重配置失败；或者是设置重建原因的内容，使得该内容对应于UE发生了重配置失败的情况；When the reconfiguration failure described in step 1 occurs in the UE and the MCG failure report/recovery process is triggered, set the reconfiguration reason so that its content indicates that the UE has reconfiguration failure; or set the reconfiguration reason content so that the content corresponds A reconfiguration failure occurred in the UE;
当UE发生步骤一中描述的同步重配置失败，并触发MCG失败报告/复原过程时，设置重建原因，使其内容指示UE发生了同步重配置失败；或者是设置重建原因的内容，使得该内容对应于UE发生了同步重配置失败的情况；When the UE fails to synchronize reconfiguration described in step 1, and triggers the MCG failure report/recovery process, set the rebuild reason so that its content indicates that the UE has failed to synchronize reconfiguration; or set the content of the rebuild reason to make the content Corresponding to the situation that the UE fails to synchronize reconfiguration;
当复原定时器正在运行时，UE检测到步骤二中描述的SCG传输发生失败，设置重建原因，使其内容指示UE发生了SCG失败，或者是设置重建原因的内容，使得该内容对应于UE发生了SCG失败的情况；When the recovery timer is running, the UE detects that the SCG transmission described in step 2 has failed, and sets the rebuild reason so that its content indicates that the UE has failed SCG, or sets the rebuild reason content so that the content corresponds to the UE occurrence The failure of SCG;
当RRC连接重建过程是由UE在复原定时器运行期间检测到SCG失败而触发的，UE设置重建原因，使其内容指示UE发生了SCG失败，或者是设置重建原因的内容，使得该内容对应于UE发生了SCG失败的情况；When the RRC connection re-establishment process is triggered by the UE detecting SCG failure during the operation of the recovery timer, the UE sets the re-establishment reason so that its content indicates that the UE has experienced SCG failure, or sets the re-establishment reason content so that the content corresponds to SCG failure occurred in the UE;
当复原定时器运行超时时，设置重建原因，使其内容指示UE发生了MCG失败报告/复原失败，或者是设置重建原因的内容，使得该内容对应于UE发生了MCG失败报告/复原失败的情况。这种情况下，还可以是设置重建原因，使其内容指示UE发生了MCG失败，或者是设置重建原因的内容，使得该内容对应于UE发生了MCG失败的情况。When the recovery timer runs out, set the rebuild reason so that its content indicates that the UE has an MCG failure report/recovery failure, or set the content of the rebuild reason so that the content corresponds to the UE’s MCG failure report/recovery failure. . In this case, it is also possible to set the re-establishment reason so that its content indicates that the UE has experienced an MCG failure, or set the content of the re-establishment reason so that the content corresponds to the UE's MCG failure.
由于在步骤一中提到，携带MCG失败相关信息的消息中可以包含指示MCG失败的失败类型时，因此，UE设置RRC连接重建的重建原因的内容的方法还可以是，UE基于携带MCG失败相关信息的消息中包含的失败类型来设置RRC连接重建请求消息中的重建原因。As mentioned in step 1, the message carrying the MCG failure related information may include the failure type indicating the MCG failure, therefore, the method for the UE to set the content of the reestablishment reason for the RRC connection reestablishment may also be that the UE carries the MCG failure related information The failure type contained in the information message is used to set the reestablishment reason in the RRC connection reestablishment request message.
上述操作的又一实现方法可以是，当RRC连接重建过程是由MCG失败报告/复原过程的失败而触发的，UE基于携带MCG失败相关信息的消息中包含的失败类型来设置RRC连接重建请求消息中的重建原因。Another implementation method of the above operation may be that when the RRC connection re-establishment process is triggered by the failure of the MCG failure report/recovery process, the UE sets the RRC connection re-establishment request message based on the failure type contained in the message carrying the MCG failure related information Reasons for reconstruction.
上述操作的又一实现方法还可以是，当RRC连接重建过程是由复原定时器运行超时而触发的，UE基于携带MCG失败相关信息的消息中包含的失败类型来设置RRC连接重建请求消息中的重建原因。Another implementation method of the above operation can also be that when the RRC connection re-establishment process is triggered by the timeout of the recovery timer, the UE sets the RRC connection re-establishment request message based on the failure type contained in the message carrying the MCG failure related information Reasons for reconstruction.
上述操作的又一实现方法还可以是，当RRC连接重建过程是由UE在复原定时器运行期间检测到SCG失败而触发的，UE基于携带MCG失败相关信息的消息中包含的失败类型来设置RRC连接重建请求消息中的重建原因。Another implementation method of the above operation may also be that when the RRC connection re-establishment process is triggered by the UE detecting SCG failure during the operation of the recovery timer, the UE sets the RRC based on the failure type contained in the message carrying the MCG failure related information The reason for reestablishment in the connection reestablishment request message.
以下示例UE如何基于携带MCG失败相关信息的消息中包含的失败类型来设置RRC连接重建请求消息中的重建原因：The following example shows how the UE sets the re-establishment reason in the RRC connection re-establishment request message based on the failure type contained in the message carrying MCG failure-related information:
示例一Example one
UE设置RRC连接重建请求消息中的重建原因与UE发送的、携带MCG失败相关信息的消息中的重建原因相同或者相关联：The UE sets that the reason for reestablishment in the RRC connection reestablishment request message is the same as or is related to the reason for reestablishment in the message sent by the UE that carries information about MCG failure:
这里以失败类型为“MCG无线链路失败”为例，当UE在携带MCG失败相关信息的消息中的失败类型设置的是MCG无线链路失败，那么UE可以设置RRC连接重建请求消息中的重建原因的内容为MCG无线链路失败，或者是设置重建原因的内容，使其对应于MCG无线链路失败这一情况。还可以理解为，UE设置RRC连接重建请求消息中的重建原因的内容，使得基站接收到该重建原因，能够获知UE曾发生了MCG无线链路失败。步骤一中提到的其他的失败类型，同样适用于上述操作。Here, taking the failure type as "MCG radio link failure" as an example, when the failure type in the message carrying MCG failure related information is set to MCG radio link failure, the UE can set the reestablishment in the RRC connection reestablishment request message The content of the cause is the failure of the MCG wireless link, or the content of the rebuild cause is set to correspond to the failure of the MCG wireless link. It can also be understood that the UE sets the content of the re-establishment reason in the RRC connection re-establishment request message, so that the base station receives the re-establishment reason and can learn that the UE has experienced an MCG radio link failure. The other failure types mentioned in step one are also applicable to the above operations.
示例二Example two
UE将失败类型进行分类，不同类别的失败类型对应不同的重建原因，相同类别的失败类型对应于相同的重建原因：The UE classifies the failure types. Different types of failure types correspond to different reconstruction reasons, and the same types of failure types correspond to the same reconstruction reasons:
例如：当UE在携带MCG失败相关信息的消息中的失败类型设置的是 重配置失败，那么UE可以设置RRC连接重建请求消息中的重建原因的内容为重配置失败，对应于重配置失败这样一种情况；For example, when the failure type of the UE in the message carrying the MCG failure related information is set to reconfiguration failure, the UE can set the reconfiguration reason in the RRC connection reestablishment request message as reconfiguration failure, which corresponds to the reconfiguration failure. A situation;
当UE在携带MCG失败相关信息的消息中的失败类型设置的是同步重配置失败，那么UE可以设置RRC连接重建请求消息中的重建原因的内容为同步重配置失败，对应于同步重配置失败这样一种情况；When the failure type of the UE in the message carrying the MCG failure related information is set to the synchronization reconfiguration failure, the UE can set the reconfiguration reason in the RRC connection reconfiguration request message as the synchronization reconfiguration failure, which corresponds to the synchronization reconfiguration failure. A situation
当UE在携带MCG失败相关信息的消息中的失败类型设置的是MCG无线链路失败或者MCG MAC报告随机接入问题，又或者是RLC层达到最大传输次数，又或者是指示完整性保护校验失败，那么UE可以设置RRC连接重建请求消息中的重建原因的内容为其他失败或者统称为MCG失败，对应于MCG失败这样一种情况。When the failure type of the UE in the message carrying the MCG failure related information is set to MCG radio link failure or MCG MAC report random access problem, or the RLC layer reaches the maximum number of transmissions, or it indicates integrity protection check If it fails, the UE may set the content of the re-establishment reason in the RRC connection re-establishment request message to other failures or collectively referred to as MCG failure, which corresponds to a situation where MCG fails.
【实施例2】[Example 2]
实施例2是对实施例1的又一种实现方式，主要差别在步骤二和步骤三。Embodiment 2 is another implementation of Embodiment 1, and the main difference is in step two and step three.
在实施例1中，UE在步骤二中检测到复原过程发生了失败，在步骤三UE基于该检测结果触发RRC连接重建过程。In Embodiment 1, the UE detects that the restoration process has failed in step 2, and in step 3, the UE triggers the RRC connection re-establishment process based on the detection result.
根据检测到复原过程发生了失败的多种情况，上述过程的又一种实现方式可以是：According to the detection of multiple failures in the restoration process, another implementation of the above process can be:
-当复原定时器运行超时的时候，用户设备UE触发RRC连接重建过程；或-When the recovery timer runs out, the user equipment UE triggers the RRC connection re-establishment process; or
-当复原定时器正在运行时，用户设备UE检测到SCG传输发生失败时，那么用户设备UE触发RRC连接重建过程；或-When the recovery timer is running and the user equipment UE detects that the SCG transmission fails, the user equipment UE triggers the RRC connection re-establishment process; or
-当UE触发/启动MCG失败报告/复原过程，如果UE检测到SCG传输发生失败时，那么用户设备UE触发RRC连接重建过程。-When the UE triggers/starts the MCG failure report/recovery process, if the UE detects that the SCG transmission fails, the user equipment UE triggers the RRC connection re-establishment process.
又或者是RRC连接重建过程可以在下述任一情况下被触发(trigger)/启动(initiation)：Or the RRC connection re-establishment process can be triggered/initiated in any of the following situations:
-复原定时器运行超时；或-The recovery timer runs out; or
-复原定时器正在运行，UE检测到SCG传输发生失败；或-The recovery timer is running and the UE detects that the SCG transmission has failed; or
-UE在MCG失败报告/复原过程中检测到SCG传输发生失败。-The UE detects SCG transmission failure during the MCG failure report/recovery process.
在上述情况下触发的RRC连接重建过程，UE向基站发送RRC连接重 建请求消息(RRCReestablishmentRequest message)。在这条消息中，UE设置RRC连接重建的重建原因的内容。设置的方法可以是实施例1中描述的任一方法。In the RRC connection reestablishment process triggered in the above situation, the UE sends an RRC connection reestablishment request message (RRC Reestablishment Request message) to the base station. In this message, the UE sets the content of the reason for the reestablishment of the RRC connection. The setting method can be any method described in Embodiment 1.
其余的过程都与实施例1中描述的相同。The rest of the process is the same as that described in Example 1.
