技术领域technical field
本申请属于无线通信技术领域，具体涉及一种无线链路恢复的方法及装置。The present application belongs to the technical field of wireless communication, and in particular relates to a method and device for restoring a wireless link.
背景技术Background technique
当前，若用户设备(User Equipment，UE)(也称为终端)移动至主小区组(Master Cell Group，MCG)网络覆盖较差的区域，导致了MCG无线链路故障(Radio Link Failure，RLF)，可通过辅小区组(Secondary Cell Group，SCG)上报MCG链路故障信息(Failure Information message)，该信息包括UE的测量结果。主节点(Master Node，MN)可基于上报的MCG链路故障信息，对UE下一步行为进行指示，如切换至其他小区。Currently, if a user equipment (User Equipment, UE) (also called a terminal) moves to an area where the network coverage of the master cell group (Master Cell Group, MCG) is poor, it will cause MCG radio link failure (Radio Link Failure, RLF) , the MCG link failure information (Failure Information message) can be reported through the secondary cell group (Secondary Cell Group, SCG), and the information includes the measurement result of the UE. Based on the reported MCG link failure information, the master node (Master Node, MN) can instruct the next behavior of the UE, such as switching to other cells.
然而，当前流程终端与MCG之间中断时间较长，导致信令及数据丢失，传输可靠性较低。However, in the current process, the interruption time between the terminal and the MCG is relatively long, resulting in loss of signaling and data, and low transmission reliability.

下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的无线链路恢复的方法及装置进行详细地说明。The method and device for restoring a wireless link provided by the embodiments of the present application will be described in detail below through some embodiments and application scenarios with reference to the accompanying drawings.
下面首先对本申请涉及的通信名词进行简单说明。Firstly, the communication terms involved in this application will be briefly described below.
1、无线链路故障(Radio link Failure，RLF)1. Radio link Failure (RLF)
当UE处于无线资源控制(Radio Resource Control，RRC)连接态(RRC_CONNECTED)态时，UE会基于参考信号(同步信号块(Synchronization Signal and PBCH block，SSB)或信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS))和网络配置的参考信号质量阈值，对激活带宽部分(bandwidth Part，BWP)进行无线链路监测(Radio Link Monitoring，RLM)。When the UE is in the Radio Resource Control (RRC) connected state (RRC_CONNECTED), the UE will base on the reference signal (Synchronization Signal and PBCH block, SSB) or channel state information reference signal (Channel State Information Reference Signal, CSI-RS)) and the reference signal quality threshold configured by the network, and perform radio link monitoring (Radio Link Monitoring, RLM) on the active bandwidth part (bandwidth Part, BWP).
RLM可基于SSB或CSI-RS：RLM can be based on SSB or CSI-RS:
对于包括发送SSB的频段的激活BWP，可基于SSB进行RLM；For active BWPs that include frequency bands that transmit SSBs, RLM can be performed based on SSBs;
否则，可基于CSI-RS进行RLM。Otherwise, RLM can be done based on CSI-RS.
当以下条件之一满足时，UE会判定发生了无线链路故障RLF：When one of the following conditions is met, the UE will determine that a radio link failure RLF has occurred:
物理层指示无线网故障后启动的计时器(即T310)超时；The timer (ie T310) started after the physical layer indicates that the wireless network fails is overtime;
T310在运行过程中，触发了测量报告上报后启动的计时器(即T312)超时；During the operation of T310, the timer (ie T312) started after the report of the measurement report is triggered to time out;
随机接入信道(Random Access Channel，RACH)过程失败；The random access channel (Random Access Channel, RACH) process fails;
无线链路控制(Radio Link Control，RLC)故障。Radio Link Control (RLC) failure.
当UE判定RLF后，UE将保持在RRC_CONNECTED状态，并选择一个合适的小区，然后启动RRC重建流程(RRC connection re-establishment)；若在判定RLF后一定时间内(即T311)没有找到合适的小区，则进入RRC空闲态(RRC_IDLE)。After the UE determines RLF, the UE will remain in the RRC_CONNECTED state, select a suitable cell, and then start the RRC connection re-establishment process (RRC connection re-establishment); if no suitable cell is found within a certain period of time (ie T311) after the RLF is determined , then enter the RRC idle state (RRC_IDLE).
2、快速MCG链路恢复(Fast MCG link recovery)2. Fast MCG link recovery
对于双连接(Dual Connectivity,DC)下的UE，如果UE检测到MCG的无线链路故障，并且配置了快速MCG链路恢复(fast MCG link recovery)，UE将触发快速MCG链路恢复。否则，UE启动RRC重建流程(RRC connection re-establishment)。For a UE under Dual Connectivity (DC), if the UE detects a MCG radio link failure and is configured with fast MCG link recovery (fast MCG link recovery), the UE will trigger fast MCG link recovery. Otherwise, the UE starts the RRC re-establishment process (RRC connection re-establishment).
请参考图2，在快速MCG链路恢复期间，UE暂停MCG传输，并通过SCG向主节点(MasterNode，MN)上报MCGFailureInformation(MCG失败消息)消息。其中，SCG通过分离式无线承载1(split Signaling Radio Bearer1，split SRB1)或SRB3发送。若通过SRB3发送，需要将MCGFailureInformation消息封装在ULInformationTransferMRDC(上行链路信息传输多无线接入技术双连接)消息中发送至SCG后，SCG将该消息转发至MN。Please refer to FIG. 2 , during the recovery of the fast MCG link, the UE suspends MCG transmission, and reports an MCGFailureInformation (MCG failure message) message to the master node (MasterNode, MN) through the SCG. Wherein, the SCG is sent through a split radio bearer 1 (split Signaling Radio Bearer1, split SRB1) or SRB3. If it is sent through SRB3, the MCGFailureInformation message needs to be encapsulated in a ULInformationTransferMRDC (uplink information transfer multi-radio access technology dual connectivity) message and sent to the SCG, and the SCG forwards the message to the MN.
UE根据MN和辅节点(Secondary Node，SN)的测量配置进行测量，并在MCGFailureInformation消息中包括测量结果。如果UE在快速MCG链路恢复启动后一定时间内没有收到RRCReconfiguration(无线资源控制重配置)、MobilityFromNRCommand(切换到NR的命令)、MobilityFromEUTRACommand(切换到EUTRA的命令)或RRCRelease(无线资源控制释放)消息，则启动RRC重建流程RRC connection re-establishment。The UE performs measurement according to the measurement configuration of the MN and the secondary node (Secondary Node, SN), and includes the measurement result in the MCGFailureInformation message. If the UE does not receive RRCReconfiguration (radio resource control reconfiguration), MobilityFromNRCommand (command to switch to NR), MobilityFromEUTRACommand (command to switch to EUTRA) or RRCRelease (radio resource control release) within a certain period of time after the fast MCG link recovery starts message, start the RRC reconstruction process RRC connection re-establishment.
MN收到MCGFailureInformation消息后，可以通过SCG的split SRB1或SRB3承载向UE发送RRCReconfiguration、MobilityFromNRCommand、MobilityFromEUTRACommand或RRCRelease消息。在收到RRCReconfiguration、MobilityFromNRCommand或MobilityFromEUTRACommand消息后，UE恢复所有无线承载的MCG传输。在收到RRCRelease消息后，UE释放所有无线承载和配置。After receiving the MCGFailureInformation message, the MN can send a RRCReconfiguration, MobilityFromNRCommand, MobilityFromEUTRACommand or RRCRelease message to the UE through the split SRB1 or SRB3 bearer of the SCG. After receiving the RRCReconfiguration, MobilityFromNRCommand or MobilityFromEUTRACommand message, the UE resumes MCG transmission for all radio bearers. After receiving the RRCRelease message, the UE releases all radio bearers and configurations.
3、分离式无线承载(Split SRB)3. Split Radio Bearer (Split SRB)
对于多无线接入技术双连接(Multi-RAT Dual Connectivity，MR-DC)，SRB1和SRB2都支持Split SRB(SRB0和SRB3不支持Split SRB)。请参考图3，Split SRB上的RRC协议数据单元(Protocol Data Unit，PDU)使用NR分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)进行加密和完整性保护。Split SRB可以由MN在SN添加和/或修改流程中配置。UE可以同时配置Split SRB和SRB3。For Multi-RAT Dual Connectivity (MR-DC), both SRB1 and SRB2 support Split SRB (SRB0 and SRB3 do not support Split SRB). Please refer to Figure 3. The RRC protocol data unit (Protocol Data Unit, PDU) on the Split SRB uses the NR packet data convergence protocol (Packet Data Convergence Protocol, PDCP) for encryption and integrity protection. Split SRB can be configured by the MN during the SN addition and/or modification process. UE can configure Split SRB and SRB3 at the same time.
对于分离式SRB，下行链路的传输路径选择取决于网络实现。对于上行链路，UE基于MN下发的RRC配置，确定使用MCG路径或在MCG和SCG上重复传输。该RRC配置分为两部分：分离式承载(Split Bearer)及PDCP重复(duplication)。For the split SRB, the selection of the downlink transmission path depends on the network implementation. For the uplink, the UE determines to use the MCG path or repeat transmission on the MCG and SCG based on the RRC configuration delivered by the MN. The RRC configuration is divided into two parts: Split Bearer and PDCP duplication.
Split Bearer通过moreThanOneRLC(多于一条无线链路控制)字段配置，配置之后即为激活状态，没有激活和去激活过程。Split Bearer is configured through the moreThanOneRLC (more than one radio link control) field. After configuration, it is in the active state, and there is no activation and deactivation process.
PDCP duplication通过pdcp-Duplication字段配置。对于SRB，配置PDCP duplication的时候就默认是激活的，后续可以通过媒体接入控制控制单元(Media Access Control Control Element，MAC CE)去激活和激活。若SRB处于PDCP duplication激活状态，则SRB承载的PDCP数据协议数据单元(Data PDU)在各无线链路控制实体(RLC entities)上重复发送。PDCP duplication is configured through the pdcp-Duplication field. For SRB, when PDCP duplication is configured, it is activated by default, and can be deactivated and activated through the Media Access Control Control Element (MAC CE) later. If the SRB is in the PDCP duplication active state, the PDCP data protocol data unit (Data PDU) carried by the SRB is repeatedly sent on each radio link control entity (RLC entities).
4、T312based fast failure recovery4. T312 based fast failure recovery
NR引入了基于T312的主小区(PCell)和辅小区组的主小区(PSCell)快速链路故障恢复方案。其原理是采用了比T310时长更短的计时器，从而更快的发现RLF并触发RRC重建流程RRC connection re-establishment。NR introduces T312-based primary cell (PCell) and secondary cell group primary cell (PSCell) fast link failure recovery scheme. The principle is to use a timer shorter than T310, so as to detect RLF faster and trigger the RRC connection re-establishment process.
如图4所示，当UE监测到PCell或PSCell底层失步并启动T310计时器之后，如果在T310运行期间UE测量到测量报告(measurement report)事件持续满足时间触发技术(Time To Trigger，TTT)时间，则UE发送measurement report(测量报告)尝试触发切换(Handover)，并启动T312定时器等待切换命令。如果T312超时没有收到切换命令，且T310定时器仍在运行，则UE不再等待T310超时，立即判决RLF并触发PCell RRC重建流程或上报PSCell SCG Failure。As shown in Figure 4, after the UE detects that the bottom layer of the PCell or PSCell is out of sync and starts the T310 timer, if the UE measures the measurement report (measurement report) event during the operation of T310 and continues to meet the time trigger technology (Time To Trigger, TTT) time, the UE sends a measurement report (measurement report) to try to trigger the handover (Handover), and starts the T312 timer to wait for the handover command. If the handover command is not received after T312 expires, and the T310 timer is still running, the UE does not wait for T310 to expire, and immediately judges RLF and triggers the PCell RRC reestablishment process or reports PSCell SCG Failure.
在图4过程中，当底层失步后，在T310运行期间，若UE监测到measurement report满足上报条件，则UE通过SRB1发送measurement report并等候响应。但是此时MCG底层已经出现了失步，在MCG无线覆盖较差的环境中，UE将无法收到MCG的RRC重配或RRC release消息，导致MCG中断时间较长，信令及数据丢失。In the process shown in Figure 4, when the bottom layer is out of synchronization, during the operation of T310, if the UE detects that the measurement report meets the reporting conditions, the UE sends the measurement report through SRB1 and waits for a response. But at this time, the bottom layer of MCG has already lost synchronization. In an environment with poor wireless coverage of MCG, UE will not be able to receive RRC reconfiguration or RRC release messages from MCG, resulting in long MCG interruption time and loss of signaling and data.
为解决现有的无线链路恢复的流程中，UE在出现MCG无线链路故障后再上报测量结果，导致MCG中断时间较长，信令及数据丢失的问题，请参考图5，本申请实施例还提供一种无线链路恢复的方法，包括：In order to solve the problem that in the existing wireless link recovery process, the UE reports the measurement results after the MCG wireless link failure occurs, resulting in a long MCG interruption time and loss of signaling and data, please refer to Figure 5.

下面结合具体应用场景，对本申请的无线链路恢复的方法进行说明。The radio link recovery method of the present application will be described below in conjunction with specific application scenarios.
本申请实施例的无线链路恢复的方法包括：The method for wireless link recovery in the embodiment of the present application includes:
步骤1：MCG向UE下发测量配置，其中包括测量上报条件，测量上报承载选择指示和测量上报反馈承载选择指示。其中，测量上报承载选择指示，用于指示UE选择上报测量结果的承载的类型；测量上报反馈承载选择指示，用于指示UE向主节点建议的上报测量的反馈的承载的类型。Step 1: The MCG sends the measurement configuration to the UE, which includes the measurement report condition, the measurement report bearer selection indication and the measurement report feedback bearer selection indication. Wherein, the measurement report bearer selection indication is used to indicate the type of bearer that the UE selects to report the measurement result; the measurement report feedback bearer selection indication is used to indicate the type of the bearer that the UE proposes to the master node for reporting measurement feedback.
与现有的测量配置相比，新增测量上报承载选择指示和测量上报反馈承载选择指示。Compared with the existing measurement configuration, a measurement report bearer selection indication and a measurement report feedback bearer selection indication are newly added.
步骤2：由于UE处于移动状态，导致MCG无线链路发生了底层失步，UE启动RLF定时器T310。Step 2: Since the UE is in a moving state, the MCG radio link is out of synchronization at the bottom layer, and the UE starts the RLF timer T310.
如果UE配置了split SRB1的话，T310启动时或运行的情况下，UE还可以激活SRB1 duplication。或者，T310运行时，如果测量上报被触发，UE激活SRB1 duplication。If the UE is configured with split SRB1, the UE can also activate SRB1 duplication when the T310 is started or running. Or, when T310 is running, if the measurement report is triggered, the UE activates SRB1 duplication.
步骤3：在T310计时过程中(即监测到与第一网络设备通信的第一链路底层失步之后，在判定出所述第一链路故障之前)，UE监测到MN下发的测量配置对应的测量结果满足上报条件，则根据测量上报承载选择指示选择第一承载，并上报测量上报反馈承载选择指示，同时启动第一计时器。Step 3: During the timing of T310 (that is, after detecting that the bottom layer of the first link communicating with the first network device is out of sync, and before determining that the first link is faulty), the UE monitors the measurement configuration delivered by the MN If the corresponding measurement result satisfies the reporting condition, the first bearer is selected according to the measurement report bearer selection indication, and the measurement report feedback bearer selection indication is reported, and the first timer is started at the same time.
步骤4：若UE选择SCG的SRB3(即承载类型三)上报测量结果，则生成ULInformationTransferMRDC消息发送至SN，其中包括MN下发的测量配置对应的测量结果。Step 4: If the UE selects the SRB3 of the SCG (that is, bearer type 3) to report the measurement result, it generates a ULInformationTransferMRDC message and sends it to the SN, which includes the measurement result corresponding to the measurement configuration issued by the MN.
步骤5：SN收到ULInformationTransferMRDC消息后，将其中的测量结果封装至RRC转发(RRC TRANSFER)消息转发给MN。Step 5: After receiving the ULInformationTransferMRDC message, the SN encapsulates the measurement results in the RRC forwarding (RRC TRANSFER) message and forwards it to the MN.
步骤6：MN收到RRC TRANSFER消息后，读取其中的测量结果，并生成RRC重配或RRC释放消息，基于测量上报反馈承载选择指示，选择SCG的SRB3(承载类型六)反馈对所述第一链路的处理指示信息，则将生成的处理指示信息封装至RRC TRANSFER消息发给SN。Step 6: After the MN receives the RRC TRANSFER message, it reads the measurement results therein, and generates an RRC reconfiguration or RRC release message, and based on the measurement report feedback bearer selection indication, selects SRB3 (bearer type six) of the SCG to feed back to the first If the processing instruction information of a link is received, the generated processing instruction information is encapsulated into an RRC TRANSFER message and sent to the SN.
步骤7：SN收到RRC TRANSFER消息后，将其中的RRC重配或RRC释放消息封装至消息下行链路信息传输多无线接入技术双连接(DLInformationTransferMRDC)，转发给UE。Step 7: After receiving the RRC TRANSFER message, the SN encapsulates the RRC reconfiguration or RRC release message into the message DL Information Transfer MRDC, and forwards it to the UE.
步骤8：若UE在第一计时器超时前收到DLInformationTransferMRDC消息，则读取其中的RRC重配或RRC释放消息，进行切换或进入RRC_IDLE态。若UE在第一计时器超时前未收到DLInformationTransferMRDC消息，则UE进行RRC重建或将SCG转为MCG。Step 8: If the UE receives the DLInformationTransferMRDC message before the first timer expires, it reads the RRC reconfiguration or RRC release message therein, performs handover or enters the RRC_IDLE state. If the UE does not receive the DLInformationTransferMRDC message before the first timer expires, the UE performs RRC re-establishment or converts the SCG to the MCG.
本申请实施例中，UE在出现MCG RLF之前，可以通过SCG上报测量报告并转发至MN，从而让MN更早的进行决策，如将PCell切换到信号质量更好的小区上。In this embodiment of the application, before the MCG RLF occurs, the UE can report the measurement report through the SCG and forward it to the MN, so that the MN can make an earlier decision, such as switching the PCell to a cell with better signal quality.
