具体实施方式
为了能够更加详尽地了解本申请实施例的特点和技术内容，下面结合附图对本申请实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本申请实施例。
在对本申请实施例提供的确定无线链路连接状态的方法进行详细说明之前，先对NR系统进行简要说明。
随着人们对速率、延迟、高速移动性、能效的追求以及未来生活中业务的多样性和复杂性，3GPP国际标准组织开始研发5G。5G的主要应用场景为：增强移动超宽带(Enhance Mobile Broadband，eMBB)、低时延高可靠通信(Ultra Reliable Low Latency Communications，URLLC)、和大规模机器类通信(Massive Machine Type Communication，mMTC)。
eMBB仍然以用户获得多媒体内容、服务和数据为目标，其需求增长十分迅速。另一方面，由于eMBB可能部署在不同的场景中，便如室内，市区，农村等，其能力和需求的差别也比较大，所以不能一概而论，必须结合具体的部署场景详细分析。URLLC的典型应用包括：工业自动化，电力自动化，远程医疗操作(手术)，交通安全保障等。mMTC的典型特点包括：高连接密度，小数据量，时延不敏感业务，模块的低成本和长使用寿命等。
为了尽快实现5G网络的部署和商业应用，3GPP在2017年12底前首先完成第一个5G版本，即LTE-NR双连接(LTE-NR Dual Connectivity，EN-DC)。EN-DC的网络部署和组网架构示意图，如图1所示：LTE系统的网络设备作为主节点(Master Node，MN)，NR系统的网络设备作为辅节点(Secondary Node，SN)。
在如图2所示的EN-DC场景中，MN(LTE eNB)主要用于实现RRC功能以及通向核心网(CoreNetwork，CN)的控制面，SN(gNB)可以配置辅助的信令，例如信令承载3(Signalling Radio Bearer3，SRB3)，主要提供数据传输功能。
终端设备除了EN-DC外，还支持其他的DC形式，如NE-DC、5GC-EN-DC、以及NR-DC等。EN-DC的网络架构如图3所示，接入网络连接的核心网是EPC。NE-DC或者NR-DC的网络架构如图4所示，NGEN-DC的网络架构如图5所示，接入网络连接的核心网是5GC。
下面再对无线链路监测(Radio Link Monitoring，RLM)进行简要说明：
RLM是指监听服务小区下行链路的信道质量，物理层在规定时间内评估无线链路质量，并将信号与干扰加噪声比(Signal to Interference plus Noise Ratio，SINR)与Qin门限和Qout门限比较，如果SINR低于Qout门限，则物理层向高层上报失步(out-of-sync)指示，如果SINR高于Qin门限，则物理层向高层上报同步(in-sync)指示。
Qout门限和Qin门限是通过检测物理下行控制信道(Physical Downlink Control Channel，PDCCH)format 1-0的误块率(The radio block error ratio of Radio Link Control，BLER)来确定。其中Qin门限和Qout门限对应的BLER值是通过RRC信令per cell配置的。Qin门限和Qout门限与BLER的对应关系，如下表1所示，缺省默认值对于Qout门限，PDCCH对应的BLER为10％；缺省默认值对于Qin门限，PDCCH对应的BLER为2％。
配置 BLERout BLERin
0 10％ 2％
1 TBD TBD
表1
在RLF过程中，终端设备在网络侧的下行失步判定涉及到如下几个定时器(RLF-Timers)和常量(Constants IE)：N310，T310，N311。其中，所涉及的定时器和常量参数可以通过专用信令配置给终端设备；如果没有通过专用信令配置给终端设备，则使用系统广播(SIB1)里面的参数配置给终端设备。
当终端设备处于RRC_CONNECTED状态时，收到连续N310个“out_of_Sync”且T310，T301，T304，T311没有运行，则启动定时器T310。如果在定时器超时前收到连续N311个“in_Sync”则停止定时器T310，表面终端设备已经恢复下行同步。否则T310超时，终端设备处于下行失步状态，即RLF。
若MCG发生RLF，则终端设备执行RRC连接重建过程；若SCG发生RLF，则终端设备向MN上报SCG失败消息(SCG Failure Information)，但是并不触发RRC连接重建过程。
目前，仅支持在PCell上的T312机制，网络设备针对一些测量对象(如测量频点)配置T312；网络设备还针对一些测量事件(如A3事件或A5事件)配置是否使用T312的标识。终端设备在触发测量上报时，如果该测量事件配置使用T312、且终端设备当前的T310正在运行，则终端设备启动T312。其中，T312超时的情况下，终端设备判断无线链路失败，并触发RRC连接重建。T312停止的条件为：接收到连续N311个物理层的in-sync指示时、或者触发切换过程时、或者初始化RRC连接重建过程时、或者T310超时时。但是，PSCell是否支持T312机制尚未被明确；在PSCell支持T312机制的情况下，如何控制PCell的T312和PSCell的T312的启动或停止也尚未被明确。
本申请实施例提供的确定无线链路连接状态的方法可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、 LTE系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统或5G系统等。

本申请实施例提供的确定无线链路连接状态的方法的一种可选处理流程，如图7所示，包括以下步骤：
步骤S201，终端设备接收网络设备发送的RRC消息。
在一些实施例中，所述RRC消息为MN RRC消息，由PCell对应的第二网络设备发送至终端设备。所述MN RRC消息中携带所述PCell的第一定时器的配置信息。所述PCell的第一定时器的配置信息至少可以包括下述中的一项或多项：PCell中针对一个或多个测量对象配置的T312的时长、针对一个或多个测量上报事件配置是否使用T312的指示。
在一些实施例中，所述终端设备根据所述RRC消息的传输路径，启动至少一个第一定时器。若所述RRC消息为SN RRC消息，所述SN RRC消息可以通过两种路径发送至终端设备。一种路径是：RRC消息由PSCell对应的第一网络设备发送至主小区PCell对应的第二网络设备，所述RRC消息再由所述第二网络设备通过SRB1发送至所述终端设备。在具体实施时，PSCell对应的第一网络设备将SN RRC消息发送至PCell对应的第二网络设备，所述PCell对应的第二网络设备再将SN RRC消息以容器(container)的形式封装在MN RRC消息中，并通过SRB1将封装了SN RRC消息的MN RRC消息发送至终端设备。另一种路径是：所述RRC消息由PSCell对应的第一网络设备通过SRB3发送至所述终端设备。其中，所述SN RRC消息中携带所述PSCell的第一定时器的配置信息。所述SPCell的第一定时器的配置信息至少可以包括下述中的一项或多项：PSCell中针对一个或多个测量对象配置的T312的时长、针对一个或多个测量上报事件配置是否使用T312的指示。
在一些实施例中，所述第一定时器为T312，所述第二定时器为T310。
步骤S202，在与所述终端设备对应的第二定时器正在运行、且在测量对象上满足测量事件上报的情况下，若所述网络设备对应的第一定时器未启动，所述终端设备根据所述RRC消息启动至少一个第一定时器。
在一些实施例中，终端设备接收到网络设备发送的RRC消息后，还可以根据所述RRC消息中的测量配置进行无线资源管理(Radio Resource Management，RRM)测量；在与终端设备对应的第二定时器正在运行、测量事件配置了使用第一定时器的指示，且在测量对象上满足测量事件上报的情况下，若所述网络设备对应的第一定时器未启动，所述终端设备根据所述RRC消息启动至少一个第一定时器。
在一些实施例中，第一定时器包括PCell对应的第一定时器和PSCell对应的第一定时器的情况下，所述终端设备根据传输SN RRC消息的路径确定启动PCell对应的第一定时器和PSCell对应的第一定时器中的一个。
下面分别针对不同的传输SN RRC消息的路径，对终端设备启动第一定时器进行说 明。
若终端设备通过SRB1接收SN RRC消息，当前PCell上的第二定时器在运行，且当前没有正在运行的PCell对应的第一定时器，则终端设备启动PCell对应的第一定时器。
若终端设备通过SRB3接收SN RRC消息，当前PSCell上的第二定时器在运行，且当前没有正在运行的PSCell对应的第一定时器，则终端设备启动PSCell对应的第一定时器。
还有一些实施例中，第一定时器包括PCell对应的第一定时器和PSCell对应的第一定时器的情况下，所述终端设备启动PCell对应的第一定时器和PSCell对应的第一定时器。
在具体实施时，在PCell对应的第二定时器正在运行的情况下，若所述PCell对应的第一定时器未启动，所述终端设备启动与所述PCell对应的第一定时器；在PSCell对应的第二定时器正在运行的情况下，若所述PSCell对应的第一定时器未启动，所述终端设备启动与所述PSCell对应的第一定时器。
因此，根据不同的场景，终端设备可以启动PCell对应的第一定时器和PSCell对应的第一定时器中的任意一个，终端设备也可以启动PCell对应的第一定时器和PSCell对应的第一定时器。
步骤S203，终端设备基于所述第一定时器确定服务小区的无线链路连接状态。
在一些实施例中，终端设备根据第一定时器是否超时，确定所述服务小区和/或所述服务小区所在的小区组的无线链路连接状态。在具体实施时，终端设备可以根据PCell对应的第一定时器和/或PSCell对应的第一定时器是否超时，确定所述服务小区和/或所述服务小区所在的小区组的无线链路连接状态。
下面分别针对PCell对应的第一定时器和/或PSCell对应的第一定时器的超时情况，对终端设备确定所述服务小区和/或所述服务小区所在的小区组的无线链路连接状态进行说明。
针对终端设备通过SRB1接收SN RRC消息的情况，终端设备启动PCell对应的第一定时器。在PCell对应的第一定时器超时的情况下，所述终端设备确定所述服务小区和/或所述服务小区所在的主小区组的无线链路连接失败。在所述服务小区和/或所述服务小区所在的主小区组的无线链路连接失败的情况下，所述终端设备可以触发连接重建立过程；终端设备也可以向PSCell对应的第一网络设备发送主小区组失败消息(SCG Failure Information)。在PCell对应的第一定时器超时之前，所述终端设备通过SRB1接收到包括PSCell变更(change)的RRC消息的情况下，所述终端设备可以执行PSCell变更；所述终端设备还可以停止运行所述PCell对应的第一定时器。
针对终端设备通过SRB3接收SN RRC消息的情况，终端设备启动与所述PSCell对应的第一定时器。在PSCell对应的第一定时器超时的情况下，所述终端设备确定所述服务小区和/或所述服务小区所在的辅小区组的无线链路连接失败。在所述服务小区和/或所述服务小区所在的辅小区组的无线链路连接失败的情况下，所述终端设备还可以向PCell对应的第二网络设备发送辅小区组失败消息。在PSCell对应的第一定时器超时前，所述终端设备通过SRB3接收到包括PSCell变更的RRC消息的情况下，所述终端设备 可以执行PSCell变更，所述终端设备还可以停止运行所述PSCell对应的第一定时器。
针对终端设备启动与所述PSCell对应的第一定时器和与所述PCell对应的第一定时器的情况，若PCell对应的第一定时器超时，所述终端设备确定所述服务小区和/或所述服务小区所在的主小区组的无线链路连接失败；所述终端设备可以触发连接重建立过程，所述终端设备也可以向PSCell对应的第一网络设备发送主小区组失败消息。若PSCell对应的第一定时器超时，所述终端设备确定所述服务小区和/或所述服务小区所在的辅小区组的无线链路连接失败，所述终端设备也可以向PCell对应的第二网络设备发送辅小区组失败消息。若在PSCell对应的第一定时器和PCell对应的第一定时器中的至少一个超时前，即PSCell对应的第一定时器超时前、或PCell对应的第一定时器超时前、或PSCell对应的第一定时器超时前和PCell对应的第一定时器超时前，所述终端设备接收到包括PSCell变更的RRC消息的情况下，所述终端设备可以执行PSCell变更；所述终端设备也可以停止运行所述PSCell对应的第一定时器和所述PCell对应的第一定时器。
