Description

无线链路失败处理方法及相关产品 技术领域
本申请涉及通信技术领域，尤其涉及一种无线链路失败处理方法及相关产品。
背景技术
在无线通信系统中，终端根据网络侧发送的载波信息对使用该载波的相邻小区的信号质量进行检测。对于长期演进增强(long-term evolution advance，LTE-A)系统等载波聚合系统，终端可能同时拥有多个为它服务的载波，在一个基站下的载波聚合称为聚合小区。当聚合小区为终端提供服务时，终端可以同时使用多个上行和下行载波进行数据传输。如果仅有部分载波(上行和/或下行)发生了无线链路失败，终端仍可以通过其他没有失败的载波与基站通信。只有当全部载波(下行和/或上行)都发生了无线链路失败，终端才判定无线链路失败，并发起无线资源控制(Radio Resource Control，RRC)连接重建立过程来恢复与基站的信令连接。目前新无线(new radio)系统的讨论中，对于RLC实体，如果对应的逻辑信道配置的小区组全部是辅小区，则当AM RLC的某一个RLC SDU重传达到最大次数的时候，可以不用触发RRC重配置，而只需要报告重传达到最大次数事件，从而减少重配置给终端造成的影响。但是，目前并没有讨论如何对RLC实体进行相应配置。
发明内容

具体实施方式
下面将结合附图对本申请实施例中的技术方案进行描述。
示例的，图1A示出了本申请涉及的无线通信系统。该无线通信系统100可以工作在高频频段上，不限于长期演进(Long Term Evolution，LTE)系统，还可以是未来演进的第五代移动通信(the 5th Generation，5G)系统、新空口(NR)系统，机器与机器通信(Machine to Machine，M2M)系统等。该无线通信系统100可包括：一个或多个网络设备101，一个或多个终端103，以及核心网设备105。其中：网络设备101可以为基站，基站可以用于与一个或多个终端进行通信，也可以用于与一个或多个具有部分终端功能的基站进行通信(比如宏基站与微基站)。基站可以是时分同步码分多址(Time Division Synchronous Code Division Multiple Access，TD-SCDMA)系统中的基站收发台(Base Transceiver Station，BTS)，也可以是LTE系统中的演进型基站(Evolutional Node B，eNB)，以及5G系统、新空口(NR)系统中的基站。另外，基站也可以为接入点(Access Point，AP)、传输节点(Trans TRP)、中心单元(Central Unit，CU)或其他网络实体，并且可以包括以上网络实体的功能中的一些或所有功能。核心网设备105包括接入和移动管理功能(Access and Mobility Management Function，AMF)实体，用户面功能(User Plane Function，UPF)实体和会话管理功能(Session Management Function，SMF)等核心网侧的设备。终端103可以分布在整个无线通信系统100中，可以是静止的，也可以是移动的。在本申请的一些实施例中，终端103可以是移动设备(如智能手机)、移动台(mobile station)、移动单元(mobile unit)、M2M终端、无线单元，远程单元、用户代理、移动客户端等等。
需要说明的，图1A示出的无线通信系统100仅仅是为了更加清楚的说明本申请的技术方案，并不构成对本申请的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请提供的技术方案对于类似的技术问题，同样适用。
下面对本申请涉及的相关技术进行介绍。
目前，在第五代移动通信技术(5th-Generation，5G)以及NR系统中，对于数据复制传输，在NR目前的讨论中，已经同时基于PDCP duplication方式进行数据复制传输，提高数据传输可靠性。NR目前定义了两种架构支持数据复制传输：对于载波聚合情况(carrier  aggregation，CA)，支持数据复制传输(data duplication)的方案利用PDCP层的复制数据功能，使复制的PDCP PDU分别传输到两个RLC entity(两个不同的逻辑信道)，并最终保证复制的PDCP PDU能够在不同物理层聚合载波上传输，从而达到频率分集增益以提高数据传输可靠性。具体的协议结构如图1B所示，无线链路控制层RLC层实体对应的逻辑信道可以配置一个或者一组小区(组)，CA duplication下的两个逻辑信道所配置的小区(组)不同，这样可以使得复制的PDCP PDU在不同的载波传输，从而提高传输分集效果，已达到提高可靠性的目前。在NR RAN2讨论中，在第99次会议讨论中，有如下结论：#99Agreements
1.RLC reports maxNumberofRLC retransmissions are reached to RRC.
2.For a logical channel restricted to one or multiple SCell(s)(i.e.logical channel configured for duplication)UE reports the failure to the gNB(e.g.SCell-RLF)but no RRC re-establishment happens.
对于RLC实体，如果对应的逻辑信道配置的小区组全部是辅小区，则当AM RLC的某一个RLC SDU重传达到最大次数的时候，可以不用触发RRC重配置，只报告重传达到最大次数事件，从而减少重配置给UE造成的影响。但是，目前并没有讨论如何对RLC实体进行相应配置。
针对上述问题，本申请实施例提出以下实施例，下面结合附图进行详细描述。
请参阅图2，图2是本申请实施例提供的一种无线链路失败处理方法，应用于上述示例通信系统中的终端，所述终端包括逻辑链路控制RLC层实体，该方法包括：
在201部分，所述终端当所述RLC层实体达到最大重传次数，根据所述RLC层实体的配置触发通信失败过程。
其中，所述RLC层实体达到最大重传次数是指所述RLC层数据重传次数达到预配置的最大重传阈值，具体可以是所述RLC层实体处理的RLC服务数据单元SDU关联的重传计数器。
其中，所述最大重传次数可以由协议预先约定，数值可以是2次、3次、4次等，此处不做唯一限定。
其中，RLC层位于分组数据汇聚协议PDCP层和媒体接入控制MAC层之间。它通过服务接入点(Service AccessPoint，SAP)与PDCP层进行通信，并通过逻辑信道与MAC层进行通信。每个终端的每个逻辑信道都有一个RLC层实体。RLC层实体从PDCP层接收到的数 据，或发往PDCP层的数据被称作RLC SDU(或PDCP PDU)。RLC实体从MAC层接收到的数据，或发往MAC层的数据被称作RLC PDU(或MAC SDU)。
RLC层的功能是由RLC实体来实现的。一个RLC实体可以配置成以下3种模式之一：(1)透传模式TransparentMode(TM)：对应TM RLC实体，简称TM实体。该模式可以认为是空的RLC，因为这种模式下只提供数据的透传(passthrough)功能。(2)非确认模式UnacknowledgedMode(UM)：对应UM RLC实体，简称UM实体。该模式提供除重传和重分段外的所有RLC功能，因此提供了一种不可靠的传输服务。(3)确实模式AcknowledgedMode(AM)：对应AM RLC实体，简称AM实体。通过出错检测和重传，AM模式提供了一种可靠的传输服务。该模式提供了所有的RLC功能。
可以看出，本申请实施例中，终端当所述RLC层实体达到最大重传次数，根据所述RLC层实体的配置触发通信失败过程。由于不同的RLC实体对应的配置可以不同，从而终端能够区分不同的RLC层实体配置，以触发不同的无线链路失败过程，如此可以尽可能减少终端的无线链路中断，并及时对链路失败进行恢复，有利于提高终端无线通信的可靠性。
在一个可能的示例中，所述通信失败包括以下任意一种：
无线链路失败、辅小区组SCG无线链路失败、辅小区SCell无线链路失败。
其中，所述无线链路失败又称为主小区组MCG无线链路失败。
可见，本示例中，由于通信失败过程包括多种链路失败情形中的一种，也就是说，在5G NR系统中，终端能够更加精确的发起无线链路失败过程，避免未及时识别无线链路失败而导致中断时延过长，尽可能减少终端的无线链路中断，并及时对链路失败进行恢复，有利于提高终端无线通信的可靠性。
在一个可能的示例中，所述RLC层实体对应的逻辑信道所配置的载波集合包含主小区Pcell；所述根据所述RLC层实体的配置触发通信失败过程，包括：

(2)重置MAC层(reset MAC)。
(3)初始化RRC连接重建立请求消息的传输(initiate transmission of the RRCConnectionReestablishmentRequest message)。
其中，所述无线链路失败又称为主小区组MCG无线链路失败。
可见，本示例中，针对RLC层实体对应的逻辑信道所配置的载波集合包含主小区Pcell的情况，终端能够根据RLC层实体的配置触发无线链路失败过程，暂停除信号无线承载SRB0之外的全部无线承载，重置MAC层，以及初始化RRC连接重建立请求消息的传输，及时对链路失败进行恢复，有利于提高终端无线通信的可靠性。
