Description

用户设备的控制方法以及用户设备 技术领域
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。
背景技术
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)。
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)。
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。
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。
在这一方案中当MCG传输发生问题时,UE如何需要处理当前的承载是需要解决的问题;相应地,当UE接收到RRC重配置消息后,如何恢复逻辑链路传输也是需要解决的。此外在MCG传输发生问题到UE收到重配置消息之前,如果SCG的链路也出现了问题,UE需要如何处理也是需要解决的。
发明内容
本发明针对以下问题提出了解决方案,上述问题包括:当MCG传输发生问题时,UE如何需要处理当前的承载;当UE接收到RRC重配置消息后,如何恢复逻辑链路传输;以及在MCG传输发生问题到UE收到重配置消息之前,如果SCG的链路也出现了问题,UE需要如何处理。具体地,本发明提供了一种用户设备的控制方法以及用户设备。
根据本发明的第一方面,提供了一种用户设备UE的控制方法,包括:所述UE基于主小区组MCG、辅小区组SCG进行通信;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,执行MCG失败处理操作;和所述UE向基站发送携带或指示MCG失败相关的信息的消息。
在上述控制方法中,在检测到所述MCG传输中发生了失败的情况下,所述UE启动或者触发向所述基站发送携带或指示MCG失败相关信息的消息的MCG失败通知过程,在所述MCG失败通知过程的初始化或者开始的操作中,执行所述MCG失败处理操作。

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。
在步骤S101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。
在步骤S102中,用户设备UE对基于MCG的传输中是否发生失败进行检测。
其中,基于MCG的传输中所发生的失败至少包含以下的至少一种情况:MCG无线链路失败;MCG的下层指示完整性保护校验失败;MCG的RLC指示达到了最大允许的发送次数或则重传输次数;和MCG MAC报告随机接入问题。
在步骤S102中,在用户设备UE检测到MCG传输中发生了失败的情况下,进入步骤S103,用户设备UE执行MCG发生了失败的情况下的处理操作,上述处理操作可称为“MCG失败处理操作”。
其中,该“MCG失败处理操作”包含以下的至少一种操作:挂起所有SRB在MCG上的传输;挂起所有DRB在MCG上的传输;挂起除了SRB0以外的所有的SRB在MCG上的传输;挂起split SRB在MCG上的传输;挂起除了SRB0以外的MCG SRB;和挂起所有的MCG DRB。
进而,在步骤S104中,用户设备UE向基站发送携带或指示MCG失败相关的信息的消息。具体而言,该信息由split SRB传输。例如SRB1被配置为split SRB,则该消息经由SRB1传输。
另外,在步骤S102中,在用户设备UE未检测到MCG传输中发生失败的情况下,也就是说在基于MCG的传输中未发生失败的情况下,返回至步骤S101,继续基于MCG、SCG来进行通信。
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。
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S203替换了步骤S103,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。
在步骤S102中,在用户设备UE检测到MCG传输中发生了失败的情况下,进入步骤S203,在步骤S203中,用户设备启动或者触发MCG失败通知过程,并且在该MCG失败通知过程的初始化或开始的操作中,执行上述MCG失败处理操作。
再有,对用户设备UE检测到MCG传输中发生了失败的情况下,SCG传输中也发生了失败时的控制方法进行说明。
用户设备UE在基于MCG的传输中发生了失败的情况下,启动恢复定时器。关于恢复定时器,可以在用户设备UE检测到MCG发生了上述的任意一种失败情况时,启动恢复定时器,也可以在用户设备UE发送携带/指示MCG失败相关的信息的消息时,启动恢复定时器。
在恢复定时器运行期间,如果用户设备UE检测到SCG中发生了失败,则触发RRC连接重建立过程,如果用户设备UE接收到RRC重配置消息,则停止定时器运行。
在恢复定时器运行超时后,用户设备UE触发RRC连接重建立过程。
其中,上述SCG中发生的失败包括以下的至少一种情况:SCG无线链路失败;SCG的底层指示完整性保护校验失败;SCG的RLC指示达到了最大允许的发送次数或者重传输次数;和SCG MAC指示随机接入问题。
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。
【实施例1】
步骤一:UE检测到MCG发生了下述的至少一种失败情况:
-MCG无线链路失败
-MCG的下层,例如PDCP层,指示完整性保护校验失败
-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 MAC报告随机接入问题
步骤二:UE执行下述的至少一种操作:
-挂起(suspend)所有SRB在MCG上的传输
-挂起(suspend)所有DRB在MCG上的传输
-挂起(suspend)除了SRB0以外的所有的SRB在MCG上的传输
-挂起(suspend)split SRB在MCG上的传输
-挂起(suspend)除了SRB0以外的MCG SRB
-挂起(suspend)所有的MCG DRB。
其中,MCG SRB是指在双连接或者多连接下的信令承载,该信令承载的RLC和MAC逻辑信道配置仅配置/工作在主小区组(MCG)。
MCG DRB是指在双连接或者多连接下的数据承载,该数据承载的RLC和MAC逻辑信道配置仅配置/工作在主小区组(Master Cell Groups,MCG)。
split SRB是指主节点(Master Node,MN)和UE之间的信令承载,该信令承载的RLC和MAC逻辑信道配置被配置在主小区组(MCG)和辅小区组(SCG)。
MCG SRB、MCG DRB、split SRB如图3所示,图中的bearer可以是SRB或者DRB。
此外,挂起SRB/DRB在MCG上的传输是指暂停/停止SRB/DRB的数据经过MCG接收和发送。如果这些SRB/DRB中的SRB/DRB的 RLC和MAC逻辑信道配置被配置在主小区组(MCG)和辅小区组(SCG),那么此类SRB/DRB的数据还可以经由SCG接收和发送;如果这些SRB/DRB中的SRB/DRB的RLC和MAC逻辑信道配置仅被配置在主小区组(MCG),那么此类SRB/DRB的数据就被暂停/停止发送。
挂起split SRB在MCG上的传输是指暂停/停止split SRB的数据经过MCG接收和发送,由于split SRB的RLC和MAC逻辑信道配置被配置在主小区组(MCG)和辅小区组(SCG),因此,尽管它在MCG上的传输被暂停/停止,还可以通过SCG进行接收和发送。
挂起SRB/DRB与挂起SRB/DRB在MCG上的传输是不同的,挂起SRB/DRB是指SRB/DRB暂停/停止工作,SRB/DRB的PDCP实体,RLC实体将不再产生或者处理数据包,所有相应的定时器也被停止。被挂起的SRB/DRB的信息将在UE的上下文中被保存,以用来以后恢复该SRB/DRB。
步骤三:UE向基站发送携带/指示MCG失败相关的信息的消息,在该消息中,可选的,UE可以报告MCG发生了上述的至少一种失败的情况。该信息由步骤二中的split SRB传输。例如SRB1被配置为split SRB,则该消息经由SRB1传输。
【实施例2】
实施例2是实施例1的又一实施方式,具体内容如下。
步骤一:UE检测到MCG发生了下述的至少一种的失败情况:
-MCG无线链路失败
-MCG的下层指示完整性保护校验失败
-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 MAC报告随机接入问题。
步骤二:UE启动/触发向基站发送携带/指示MCG失败相关信息的消息过程。
在该过程的初始化/开始的操作中UE执行下述的至少一种操作:
-挂起(suspend)所有SRB在MCG上的传输
-挂起(suspend)所有DRB在MCG上的传输
-挂起(suspend)除了SRB0以外的所有的SRB在MCG上的 传输
-挂起(suspend)split SRB在MCG上的传输
-挂起(suspend)除了SRB0以外的MCG SRB
-挂起(suspend)所有的MCG DRB。
步骤三:UE向基站发送携带/指示MCG失败相关的信息的消息,在该消息中,可选的,UE可以报告MCG发生了上述至少一种失败的情况。该信息由步骤二中的split SRB传输。例如,SRB1被配置为split SRB,则该消息经由SRB1传输。
【实施例3】
实施例3和实施例1的区别在于UE检测到MCG发生了下述至少一种的失败情况时,启动一个定时器,这里称为恢复定时器。
-MCG无线链路失败
-MCG完整性保护校验失败
-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 MAC报告随机接入问题。
在恢复定时器运行期间,如果UE检测到SCG发生了下述至少一种的失败情况时,触发RRC连接重建立过程。
-SCG无线链路失败
-SCG的底层指示完整性保护校验失败
-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 MAC指示随机接入问题。
当恢复定时器运行超时后,UE触发RRC连接重建立过程。
在恢复定时器运行期间,如果UE接收到了RRC重配置消息,那么停止定时器运行。
【实施例4】
实施例4和实施例3的区别在于UE在发送携带/指示MCG失败相关的信息的消息时,启动恢复定时器。
具体可以是UE在生成发送携带/指示MCG失败相关的信息的消息时启动恢复定时器;还可以是UE将发送携带/指示MCG失败相关的信息的消息递交给下层传输时,启动恢复定时器;还可以是UE触发向基站发送携带/指示MCG失败相关信息的消息过程后,在该过程的初始化/开始阶段启动恢复定时器。
在恢复定时器运行期间,如果UE检测到SCG发生了下述至少一种的失败情况时,触发RRC连接重建立过程。
-SCG无线链路失败
-SCG的底层指示完整性保护校验失败
-SCG的RLC指示达到了最大允许的发送次数或者重传输次数
-SCG MAC指示随机接入问题。
当恢复定时器超时后,UE触发RRC连接重建立过程。
在恢复定时器运行期间,如果UE接收到了RRC重配置消息,那么停止定时器运行。
【实施例5】
实施例5是将实施例1和3结合,或者将实施例1和4结合,UE在进行实施例1中的步骤一后,不总是执行步骤二及步骤三。具体可以是如下步骤。
步骤一:UE检测到MCG发生了下述至少一种的失败情况:
-MCG无线链路失败
-MCG的下层指示完整性保护校验失败
-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 MAC报告随机接入问题。
如果UE被配置了恢复定时器,或者被配置了恢复定时器的时长,那么UE如实施例1中所述,继续执行步骤二以及步骤三,以及如实施例3或4中所述启动恢复定时器,并进行相应的操作。
如果UE没有被配置恢复定时器,或者没有被配置恢复定时器的时长,那么UE触发RRC连接重建立过程。
【实施例6】
实施例6是将实施例2和3结合,或者将实施例2和4结合,UE在进行实施例2中的步骤一后,不总是执行步骤二及步骤三。具体可以是如下步骤。
步骤一:UE检测到MCG发生了下述至少一种的失败情况:
-MCG无线链路失败
-MCG的下层指示完整性保护校验失败
-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 MAC报告随机接入问题。
如果UE被配置了恢复定时器,或者被配置了恢复定时器的时长,那么UE如实施例2中所述,继续执行步骤二UE启动/触发向基站发送携带/指示MCG失败相关信息的消息过程,以及步骤三;以及如实施例3或4中所述启动恢复定时器,并进行相应的操作。
如果UE没有被配置恢复定时器,或者没有被配置恢复定时器的时长,那么UE触发RRC连接重建立过程。
【实施例7】
UE向基站发送前述的携带/指示MCG失败相关信息的消息之后,可能会接收到RRC重配置消息。
UE在接收到RRC重配置消息时,
如果UE MCG的传输被挂起,那么UE执行下述的至少一种操作:

-执行该SRB的PDCP data recovery,
-重建该SRB的PDCP实体,
-重建该SRB的RLC实体,
-恢复(resume)被挂起的SRB在MCG上的传输。
针对在MCG上的传输被挂起的DRB,UE执行下述的一种或多种操作:
-执行该DRB的PDCP data recovery,
-重建该DRB的PDCP实体,
-重建该DRB的RLC实体,
-和/或恢复(resume)被挂起的DRB在MCG上的传输。
针对在MCG上的传输被挂起的split SRB,UE执行下述的一种或多种操作:
-执行PDCP data recovery
-重建该split SRB的PDCP实体,
-重建该split SRB的RLC实体,
-恢复(resume)被挂起的split SRB在MCG上的传输
优选的,如果split SRB为SRB1,那么针对在MCG上的传输被挂起的SRB1,UE执行下述操作之一或多:
-执行SRB1的PDCP data recovery
-重建SRB1的PDCP实体,
-重建SRB1的RLC实体,
-恢复(resume)SRB1在MCG上的传输
针对被挂起的DRB,复原(restore)其PDCP状态和重建PDCP实体,以及恢复(resume)被挂起的DRB;
针对被挂起的SRB,复原(restore)其PDCP状态和重建PDCP实体,以及恢复(resume)被挂起的SRB。
其中,UE MCG的传输被挂起,具体的挂起过程如实施例1中的描述,即当在接收到RRC重配置消息之前,UE的MCG传输进行了如实施例1中描述的挂起操作。
如果UE MCG的传输没有被挂起,那么UE基于RRC重配置消息中指示的信息进行相应的配置。
【实施例7的变形例】
作为上述实施例7的变形例,当UE接收到RRC重配置消息时,如果这是UE在发送了如实施例1中所示的携带/指示MCG失败相关的信息的消息之后接收到的第一条RRC重配置消息,那么UE在接收到RRC重配置消息后,执行下述的至少一种操作:
针对在MCG上的传输被挂起的SRB,UE执行下述的一种或多种操作:
-执行该SRB的PDCP数据恢复流程(PDCP data recovery),
-重建该SRB的PDCP实体,
-重建该SRB的RLC实体,
-恢复(resume)被挂起的SRB在MCG上的传输。
针对在MCG上的传输被挂起的DRB,UE执行下述的一种或多种操作:
-执行该DRB的PDCP data recovery
-重建该DRB的PDCP实体,
-重建该DRB的RLC实体,
-恢复(resume)被挂起的DRB在MCG上的传输。
针对在MCG上的传输被挂起的split SRB,UE执行下述操作之一或多:
-执行该split SRB的PDCP data recovery
-重建该split SRB的PDCP实体,
-重建该split SRB的RLC实体,
-恢复(resume)被挂起的split SRB在MCG上的传输。
优选的,如果split SRB为SRB1,那么针对在MCG上的传输被挂起的SRB1,UE执行下述的一种或多种操作:
-执行SRB1的PDCP data recovery
-重建SRB1的PDCP实体,
-重建SRB1的RLC实体,
-恢复(resume)SRB1在MCG上的传输。
针对被挂起的DRB,复原(restore)其PDCP状态和重建PDCP实体,以及恢复(resume)被挂起的DRB;
针对被挂起的SRB,复原(restore)其PDCP状态和重建PDCP实体,以及恢复(resume)被挂起的SRB。
如果这不是UE在发送了如实施例1中所示的携带/指示MCG失败相关的信息的消息之后接收到的第一条RRC重配置消息,那么UE基于RRC重配置消息中指示的信息进行相应的配置。
在这一实施方案中,由于UE在发送携带/指示MCG失败相关的信息的消息之前或者同时,会进行相应的挂起操作,如实施例1和2中所示,因此,“是否是UE发送携带/指示MCG失败相关的信息的消息之后收到的RRC重配置消息”,这一判断条件与“UE MCG的传输是否被挂起”等价。
上述的PDCP数据恢复流程(PDCP data recovery)是可以参见3GPP技术规范38.323第5.5章的描述.
【实施例8】
在UE检测到MCG发生失败之后,以及在接收到RRC重配置消息之前,在这之间UE可能会检测到SCG发生失败的情况。
当UE检测到SCG发生失败情况时,根据MCG的传输是否被挂起来判断进行RRC连接重建立还是触发SCG失败信息的传输过程。具体内容如下。
当UE检测到SCG发生了下述的至少一种失败情况时,
-SCG无线链路失败,
-SCG的底层指示完整性保护校验失败,
-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 MAC指示随机接入问题。
如果MCG的传输被挂起,那么UE触发/启动RRC连接重建立过程;
如果MCG的传输没有被挂起,那么UE触发/启动发送/传输SCG失败信息的过程来报告SCG失败。
其中上述的MCG传输的挂起操作见实施例1中的描述。
【实施例8的变形例】
作为上述实施例8的变形例,当UE检测到SCG发生失败情况时,根据恢复定时器是否运行来判断进行RRC连接重建立还是触发SCG失败信息的传输过程。具体内容如下。
当UE检测到SCG发生了下述的至少一种失败情况时,
-SCG无线链路失败,
-SCG的底层指示完整性保护校验失败,
-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 MAC指示随机接入问题。
如果恢复定时器正在运行,那么UE触发/启动RRC连接重建立过程;
如果恢复定时器停止,或者没有在运行,那么UE触发/启动发送/传输SCG失败信息的过程来报告SCG失败。
其中上述的MCG传输的挂起操作见实施例1中的描述。
在这一实施方案中,由于UE在发送携带/指示MCG失败相关的信息的消息之前或者同时,会进行相应的挂起操作,并启动恢复定时器,如实施例3和4中所示,因此,“MCG的传输是否被挂起”,这一判断条件与“恢复定时器是否运行”等价。
