具体实施方式
为了便于理解，首先介绍本申请涉及的术语。
1、无线资源控制(radio resource control，RRC)
RRC是指通过一定的策略和手段进行无线资源管理、控制和调度，为上层提供无线资源参数以及控制下层的主要参数和行为。在满足服务质量的要求下，尽可能地充分利用有限的无线网络资源，确保到达规划的覆盖区域，尽可能地提高业务容量和资源利用率。
2、无线链路失败(radio link failure，RLF)
在本申请中无线链路失败(radio link failure,RLF)指一个终端设备和网络设备之间的物理层连接中断，其发生于终端设备的RRC连接态。当RLF持续一定时间仍没有恢复物理层连接，则终端设备从RRC连接态进入RRC空闲态。相应的，本申请中所述的进入RLF是指终端设备确定进入与网络设备之间的物理层连接中断状态，其中所述“进入RLF”也可以理解为进入RLF状态，或者发生RLF，或者检测到RLF。进一步，在此状态下终端设备会发起RRC连接重建。
为了更好的理解本申请实施例公开的一种邻区测量方法，下面首先对本申请实施例适用的通信系统进行描述。
请参见图1，图1为本申请实施例提供的一种通信系统的架构示意图。该通信系统可包括但不限于一个终端设备和三个网络设备，图1所示的设备数量和形态用于举例并不构成对本申请实施例的限定，实际应用中可以包括两个或两个以上的终端设备，一个、两个、四个或四个以上的网络设备。图1所示的通信系统以包括一个终端设备101和三个网络设备(图1中第一网络设备102、第二网络设备103、第三网络设备104)为例。
第一网络设备102为终端设备101的服务小区对应的网络设备，第二网络设备103为邻区a对应的网络设备，第三网络设备104为邻区b对应的网络设备。其中，邻区a和邻区b均为服务小区的邻小区。需要说明的是，图1所示的通信系统包括两个邻区(即邻区a和邻区b)仅用于举例，并不构成对本申请实施例的限定。在一种实现方式中，除了邻区a和邻区b以外，图1所示的通信系统还可以包括该服务小区的其他邻区。图1中，第一网络设备102所在的椭圆形区域为终端设备101的服务小区的覆盖区域，第二网络设备103所在的椭圆形区域为邻区a的覆盖区域，第三网络设备104所在的椭圆形区域为邻区b的覆盖区域。终端设备101同时处于服务小区、邻区a和邻区b的覆盖范围内。
其中，终端设备101可以在处于RRC连接态的情况下，获取邻区测量结果；该邻区测量结果可以包括该终端设备101的服务小区的多个邻区(如邻区a和邻区b)的信道质量信息；并在检测到无线链路失败(radio link failure，RLF)之前，根据该邻区测量结果，发起针对前述多个邻区中的目标邻区的RRC连接重建过程。图1以目标邻区为邻区b为例，并不构成对本申请实施例的限定，目标邻区还可以为邻区a。
终端设备101在检测到RLF的情况下，可以表明该终端设备101与服务小区对应的网络设备(即第一网络设备102)之间的链路质量较差，此时，会对该终端设备101的业务造成影响。因此，相较于在检测到RLF之后发起RRC连接重建过程，终端设备101在检测到RLF之前，发起RRC连接重建，有利于降低对终端设备101的业务造成的影响。
需要说明的是，本申请实施例的技术方案可以应用于各种通信系统。例如：长期演进(long term evolution，LTE)系统、第五代(5th generation，5G)移动通信系统、5G新空口(new radio，NR)系统。可选的，本申请实施例的方法还适用于未来的各种通信系统，例如6G系统或者其他通信网络等。
本申请实施例中的终端设备101是用户侧的一种用于接收或发射信号的实体，如手机。终端设备也可以称为终端(terminal)、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等。终端设备可以是手机(mobile phone)、穿戴式设备、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self-driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端、窄带物联网(narrowband internet of things，NB-IoT)中的终端设备、增强机器类型通信(enhanced machine type communication，eMTC)终端设备等等。本申请的实施例对终端设备所采用的具体技术和具体设备形态不做限定。
其中，NB-IoT和eMTC的终端设备具有低复杂度、低成本、低功耗、低带宽的特点，适用于广泛的物联网场景。例如，智能水表、智能电表、智能家居、智慧城市等。目前，大规模机器类型通信mMTC(massive Machine Type Communications，mMTC)作为5G三大应用场景之一，其中新无线轻量接入技术(new radio-Light，NR-Light)和降低能力(reduced capability,REDCAP)的接入技术赢得广泛讨论和关注，其为适应5G的发展而产生，需要具备NB-IoT、eMTC终端设备的特点。
为满足低复杂度、低成本等需求，这类终端设备不支持常规终端设备的小区切换功能。例如，这类终端设备在小区1的边缘位置因为信号变差而发生RLF之后，若这类终端设备通过小区选择，发现了合适的邻区(小区2)，则通过RRC连接重建过程重建到小区2。这样会导致这类终端设备不能及时重建到小区2，即更换小区存在较长时延。这会使得终端设备在小区1边缘与小区1进行通信(信道状态较差)需要消耗更多的功率和无线资源，并且，更换小区时间较长，会导致终端设备的通信业务较长时间中断，对终端设备的通信业务影响较大。通过实施本申请实施例，有利于缩短NB-IoT终端设备更换小区的时延，以确保NB-IoT终端设备的服务质量，以及节省功率和无线资源。
本申请实施例中的网络设备(如第一网络设备102、第二网络设备103、第三网络设备104)是网络侧的一种用于发射或接收信号的实体。例如，网络设备可以为演进型基站(evolved NodeB，eNB)、传输点(transmission reception point，TRP)、NR系统中的下一代基站(next generation NodeB，gNB)、其他未来移动通信系统中的基站或无线保真(wireless fidelity，WiFi)系统中的接入节点等。本申请的实施例对网络设备所采用的具体技术和具体设备形态不做限定。
可以理解的是，本申请实施例描述的通信系统是为了更加清楚的说明本申请实施例的技术方案，并不构成对本申请实施例提供的技术方案的限定，本领域技术人员可知，随着系统架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
下面结合附图对本申请提供的邻区测量方法及通信装置进行详细地介绍。
请参见图2，图2是本申请实施例提供的一种邻区测量方法的流程示意图。其中，步骤S201～步骤S202的执行主体为终端设备，或者为终端设备中的芯片，以下以终端设备为邻区测量方法的执行主体为例进行说明。如图2所示，该方法可以包括但不限于如下步骤：
步骤S201：终端设备在处于无线资源控制RRC连接态的情况下，获取邻区测量结果；该邻区测量结果包括该终端设备的服务小区的多个邻区的信道质量信息。
在本申请实施例中，终端设备可以在处于RRC连接态的情况下，对该终端设备的服务小区的多个邻区进行邻区测量，得到邻区测量结果。该邻区测量结果可以包括前述多个邻区中各个邻区的信道质量信息。
在本申请实施例中，小区(如邻区、服务小区)的信道质量信息可以包括信道质量参数的评估值。信道质量参数可以包括如下至少一项：参考信号接收功率(reference signal receiving power，RSRP)、接收信号强度指示(received signal strength indication，RSSI)、参考信号接收质量(reference signal receiving quality，RSRQ)、信号与干扰加噪声比(signal to interference plus noise ratio，SINR)、信噪比(signal noise ratio，SNR)、成功接收重复次数、重复发送次数、覆盖增强等级、发射功率、下行无线链路误块率、以特定误块率可靠接收假设的PDCCH的链路水平、终端设备与该小区的覆盖中心(或者与该小区对应的网络设备)之间的距离。在一种实现方式中，终端设备可以通过测量邻小区对应的网络设备发送的参考信号获取该邻小区的信号质量信息，参考信号可以包括以下至少一项：小区参考信号(cell-specific reference signal，CRS)、同步信号块(synchronization signal block，SSB)和信道状态参考信号(channel state information reference signal，CSI-RS)。
在一种实现方式中，终端设备所测量的前述多个邻区可以指如下任意一项：前述多个邻区为服务小区的同频邻区；前述多个邻区为服务小区的异频邻区；前述多个邻区中的一部分小区为服务小区的同频邻区，一部分小区为服务小区的异频邻区；前述多个邻区为服务小区的异系统邻区；前述多个邻区中的一部分小区为服务小区的异系统邻区。需要说明的是，异系统邻区的含义可以为：该终端设备的服务小区与该邻区属于不同的通信系统(如该服务小区属于4G通信系统，该邻区属于5G通信系统)，且该终端设备既支持在服务小区所属的通信系统内进行通信，也支持在该邻区所属的通信系统内进行通信。
在本申请实施例中，每个小区可以配置有邻区列表，该邻区列表可以用于指示该小区的待测邻区。例如，该邻区列表可以包含待测邻区的小区标识和/或频点等信息，用于指示终端设备测量小区标识对应的邻区，和/或指示终端设备测量相应频点上的邻区。在一种实现方式中，前述多个邻区可以为该终端设备的服务小区配置的邻区列表中的部分邻区或者全部邻区，本申请实施例对此不做限定。在一种实现方式中，可以通过如下方式确定待测邻区：当本申请实施例应用于终端设备发生移动的场景下，该终端设备可以预测接下来即将处于哪一个小区的覆盖范围内，并将预测的小区作为待测邻区。可选的，终端设备可以根据历史移动路径，预测接下来即将处于哪一个小区的覆盖范围内；或者，终端设备可以根据用户在该终端设备中输入的目的地，结合网络设备下发的覆盖信息，预测接下来即将处于哪一个小区的覆盖范围内，本申请实施例对此不做限定。
在一种实现方式中，终端设备在处于RRC连接态的情况下，可以对服务小区进行测量，得到该服务小区的信道质量信息；并在该服务小区的信道质量信息满足第一预设条件的情况下，对该终端设备的服务小区的多个邻区进行邻区测量。其中，该服务小区的信道质量信息满足第一预设条件可以表示：该服务小区的信道质量较差、变差或即将变差。该服务小区的信道质量信息可以包括信道质量参数的评估值。信道质量参数可以包括但不限于如下至少一项：参考信号接收功率RSRP、参考信号接收质量RSRQ、信号与干扰加噪声比SINR、信噪比SNR、成功接收重复次数、重复发送次数、覆盖增强等级、发射功率、下行无线链路误块率、以特定误块率可靠接收假设的PDCCH的链路水平、该终端设备与该服务小区的覆盖中心(或者该服务小区对应的网络设备)之间的距离。该服务小区的信道质量信息满足第一预设条件可以包括：例如，该服务小区的参考信号接收功率低于预设参考信号接收功率阈值。或者，该终端设备与该服务小区的覆盖中心(或者该服务小区对应的网络设备)之间的距离超过预设距离阈值，使得该终端设备接收到的来自该服务小区的信号的质量较差。通过这种方式，终端设备可以及时进行邻区测量，以便在服务小区的信道质量较差，但还未检测到RLF的情况下，根据邻区测量结果发起针对前述多个邻区中的目标邻区的RRC连接重建过程。
值得注意的是，通常，NB-IoT终端设备是在检测到RLF之后，才通过小区选择以确定合适的邻区，进而发起针对该邻区的RRC连接重建过程以更换小区。采用这种方式会导致更换小区时存在较长时延，使得NB-IoT终端设备在较差的信道状态下仍然与服务小区保持通信，消耗了更多的功率和无线资源，且较长时间的中断会对NB-IoT终端设备的通信业务造成较大影响。NB-IoT终端设备在服务小区的信道质量信息满足第一预设条件，但还未检测到RLF的情况下，对该服务小区的多个邻区进行邻区测量。可以提前确定合适的目标邻区，从而有利于缩短更换小区的时延，以确保NB-IoT终端设备的服务质量。
在一种实现方式中，在服务小区的信道质量信息满足第一预设条件的情况下，终端设备可以向该服务小区对应的网络设备发送通知，并对该服务小区的多个邻区进行邻区测量。其中，该通知可以用于指示该服务小区的信道质量信息满足第一预设条件。相应的，该网络设备接收到该通知，可以确定该服务小区的信道质量信息满足第一预设条件，也可以表示该终端设备开始进行邻区测量。在此情况下，终端设备进行邻区测量可以无需得到该网络设备的允许，即不用通过网络设备触发该终端设备进行邻区测量。通过向该网络设备发 送该通知，有利于避免该终端设备与网络设备的通信与该终端设备的邻区测量产生冲突。
在一种实现方式中，在用于配置邻区测量配置参数的网络设备与该服务小区对应的网络设备不同的情况下，该通知可以携带该邻区测量配置参数。终端设备在进行邻区测量时，无法接收到该服务小区对应的网络设备发送的信息。在用于配置邻区测量配置参数的网络设备与该服务小区对应的网络设备不同的情况下，该服务小区对应的网络设备无法获知该终端设备中配置的邻区测量配置参数，也就无法获知该终端设备在何时进行邻区测量。通过在该通知中携带终端设备中配置的邻区测量配置参数，可以使得该服务小区对应的网络设备可以获取该邻区测量配置参数，从而有利于避免该终端设备与网络设备的通信与该终端设备的邻区测量产生冲突。
需要说明的是，前述第一预设条件(例如预设参考信号接收功率阈值、预设距离阈值)可以由网络配置(例如，在系统消息或专有信令中下发)，或者可以由协议约定，或者可以由终端设备默认设置，或者可以由用户设置以及更改，本申请实施例对此不做限定。
步骤S202：该终端设备在检测到无线链路失败RLF之前，根据该邻区测量结果，发起针对前述多个邻区中的目标邻区的RRC连接重建过程。
在本申请实施例中，终端设备在获取邻区测量结果之后，即使还未检测到RLF，也可以发起针对目标邻区的RRC连接重建过程。相较于在检测到RLF之后发起RRC连接重建过程，终端设备在检测到RLF之前发起RRC连接重建，有利于确保终端设备的数据传输，降低对终端设备的业务造成的影响。另外，由于目前NB-IoT终端设备是在检测到RLF之后，才发起针对目标邻区的RRC连接重建过程以更换小区。这样会导致更换小区时存在较长时延，使得终端设备在较差的信道状态下仍然与服务小区保持通信，消耗了更多的功率和无线资源，且较长时间的中断会对终端设备的通信业务造成较大影响。通过实施本申请实施例，有利于缩短NB-IoT终端设备更换小区的时延，以确保NB-IoT终端设备的服务质量。
具体的，终端设备根据邻区测量结果，发起针对前述多个邻区中的目标邻区的RRC连接重建过程的具体实施方式可以为：终端设备根据邻区测量结果，从前述多个邻区中确定目标邻区；并发起针对该目标邻区的RRC连接重建过程。在一种实现方式中，目标邻区可以为前述多个邻区中信道质量最好的邻区，或者，目标邻区可以为前述多个邻区中信道质量参数的评估值大于预设的参数阈值的邻区。其中，该预设的参数阈值可以由网络配置，或者该预设的参数阈值可以由协议约定，或者可以由终端设备默认设置，或者可以由用户设置以及更改，本申请实施例对此不做限定。需要说明的是，前述多个邻区中信道质量参数的评估值大于前述参数阈值的邻区数量可以为一个或多个。当前述多个邻区中信道质量参数的评估值大于该参数阈值的邻区数量为多个时，目标邻区可以为信道质量参数的评估值大于该参数阈值的邻区中的任一个邻区，或者，目标邻区可以为信道质量参数的评估值大于该参数阈值的邻区中评估值最大的邻区。
在一种实现方式中，终端设备在确定目标邻区时处于服务小区的覆盖范围内，当本申请实施例应用于终端设备发生移动的场景下，该终端设备可以预测接下来即将处于哪一个邻区的覆盖范围内，此时，前述目标邻区可以为该终端设备预测的邻区。可选的，终端设备可以根据历史移动路径，预测目标邻区；或者，终端设备可以根据用户在该终端设备中 输入的目的地，结合网络设备下发的覆盖信息，预测目标邻区，本申请实施例对此不做限定。
在本申请实施例中，终端设备发起针对该目标邻区的RRC连接重建过程可以指：该终端设备向目标邻区对应的网络设备(如基站)发送RRC连接重建请求(即RRC connection reestablishment request)。目标邻区对应的网络设备接收到该RRC连接重建请求之后，可以重新为该终端设备分配无线资源。然后，该网络设备可以向该终端设备发送RRC连接重建(即RRC connection reestablishment)消息，该消息可以用于指示新分配的无线资源。终端设备收到该RRC连接重建消息之后，可以根据该消息进行无线资源配置，并向该网络设备发送RRC连接重建完成(即RRC connection reestablishment complete)消息。至此，终端设备完成针对目标邻区的RRC连接重建过程。
在本申请实施例中，终端设备在检测到RLF之前发起RRC连接重建，有利于确保终端设备的数据传输，并有利于降低对终端设备的业务造成的影响。
请参见图3，图3是本申请实施例提供的另一种邻区测量方法的流程示意图，该方法详细描述了终端设备如何根据前述邻区测量结果，发起针对目标邻区的RRC连接重建过程。其中，步骤S301～步骤S302的执行主体为终端设备，或者为终端设备中的芯片，以下以终端设备为邻区测量方法的执行主体为例进行说明。该方法可以包括但不限于如下步骤：
步骤S301：终端设备在处于无线资源控制RRC连接态的情况下，获取邻区测量结果；该邻区测量结果包括该终端设备的服务小区的多个邻区的信道质量信息。
需要说明的是，步骤S301的执行过程可参见图2中步骤S201的具体描述，此处不再赘述。
步骤S302：该终端设备在检测到无线链路失败RLF之前，在前述多个邻区中的目标邻区的信道质量信息满足第二预设条件的情况下，发起针对该目标邻区的RRC连接重建过程。
在本申请实施例中，终端设备在获取邻区测量结果之后，还可以确定该多个邻区中是否存在信道质量信息满足第二预设条件的邻区。若存在，该终端设备可以将信道质量信息满足第二预设条件的任一邻区作为目标邻区；或者，该终端设备可以将找到的第一个信道质量信息满足第二预设条件的邻区作为目标邻区；或者，该终端设备可以将信道质量信息满足第二预设条件的邻区中信道质量最好的邻区作为目标邻区，本申请实施例对此不做限定。其中，目标邻区的信道质量信息满足第二预设条件可以表示：该目标邻区的信道质量较好。通过这种方式，一方面，终端设备在检测到RLF之前发起RRC连接重建，有利于避免RLF对终端设备的业务造成影响；另一方面，目标邻区的信道质量较好，有利于终端设备获取更优质的服务，避免终端设备在服务小区的信道质量较差的时候仍然与服务小区保持通信带来的不必要的功率和无线资源的消耗。
在一种实现方式中，信道质量信息可以包括信道质量参数的评估值；目标邻区的信道质量信息满足该第二预设条件可以包括但不限于以下一项或多项：
1、目标邻区的信道质量参数的评估值与终端设备的服务小区的信道质量参数的评估值之间的差值大于第一预设阈值，该第一预设阈值大于或等于0，即目标邻区比服务小区的信道质量更好；2、该目标邻区的信道质量参数的评估值大于第二预设阈值，且该服务小区 的信道质量参数的评估值小于第三预设阈值；该第二预设阈值不小于(即大于或等于)该第三预设阈值，即服务小区的信道质量较差、目标邻区的信道质量较好，且目标邻区比服务小区的信道质量更好；
3、该目标邻区的信道质量参数的评估值与第四预设阈值之间的差值大于第五预设阈值，即目标邻区的信道质量足够好。
需要说明的是，前述第二预设条件、第一预设阈值、第二预设阈值、第三预设阈值、第四预设阈值、第五预设阈值均可以由网络配置(例如，在系统消息或专有信令中下发)，或协议约定，或者可以由终端设备默认设置，或者可以由用户设置以及更改，本申请实施例对此不做限定。
在本申请实施例中，一方面，终端设备在检测到RLF之前发起RRC连接重建，有利于避免RLF对终端设备的业务造成影响；另一方面，终端设备确定信道质量信息满足第二预设条件的目标邻区，并针对该目标邻区进行RRC连接重建，有利于终端设备获取更优质的服务，避免终端设备在服务小区的信道质量较差的时候仍然与服务小区保持通信带来的不必要的功率和无线资源的消耗。
请参见图4，图4是本申请实施例提供的又一种邻区测量方法的流程示意图，该方法详细描述了网络设备在确定终端设备的服务小区满足第一预设条件的情况下，向该终端设备发送第一指示信息，以使能该终端设备根据邻区测量配置参数进行邻区测量。其中，步骤S401的执行主体为网络设备，或者为网络设备中的芯片，步骤S402～步骤S403的执行主体为终端设备，或者为终端设备中的芯片，以下以终端设备、网络设备为邻区测量方法的执行主体为例进行说明。该方法可以包括但不限于如下步骤：
步骤S401：网络设备在确定终端设备的服务小区满足第一预设条件的情况下，向该终端设备发送第一指示信息；该第一指示信息用于指示该终端设备根据邻区测量配置参数进行邻区测量；该网络设备为该服务小区对应的网络设备。
在本申请实施例中，终端设备的服务小区满足第一预设条件可以表示：该服务小区的信道质量较差、变差或者即将变差。在此情况下，该终端设备可以进行邻区测量，以便确定合适的目标邻区，使得该终端设备将服务小区更换为该目标邻区，这样有利于确保该终端设备的数据传输。具体的，网络设备通过向该终端设备发送第一指示信息以指示该终端设备进行邻区测量。在终端设备的服务小区满足第一预设条件的情况下，网络设备通过向该终端设备发送第一指示信息以指示该终端设备进行邻区测量，有利于终端设备更及时地获取邻区测量结果，进而有利于更及时地进行RRC连接重建，降低对终端设备的业务造成的影响，还有利于避免终端设备在服务小区不满足第一预设条件的情况下进行邻区测量，造成不必要的资源消耗。
在一种实现方式中，网络设备可以通过如下方式确定终端设备的服务小区满足第一预设条件：网络设备获取以下参数中的至少一项：参考信号接收功率RSRP、参考信号接收质量RSRQ、信号与干扰加噪声比SINR、信噪比SNR、成功接收重复次数、重复发送次数、覆盖增强等级、发射功率、下行无线链路误块率、以特定误块率可靠接收假设的PDCCH的链路水平、该服务小区的覆盖中心与该终端设备之间的距离、该服务小区的负载或该服 务小区的调度情况信息，并根据所获取的信息判断该服务小区是否满足第一预设条件。可选的，终端设备上报服务小区的参考信号接收功率RSRP，若网络设备确定该终端设备的服务小区的参考信号接收功率低于预设参考信号接收功率阈值，则该网络设备可以确定该终端设备的服务小区满足第一预设条件。可选的，若该服务小区的覆盖中心与该终端设备之间的距离超过预设距离阈值，则该网络设备可以确定该服务小区满足第一预设条件。可选的，若该服务小区的负载大于预设负载，则该网络设备可以确定该服务小区满足第一预设条件。该服务小区的负载大于预设负载，会影响该服务小区中终端设备接收到的信号的质量。服务小区的负载大于预设负载可以指：接入该服务小区的终端设备的数量大于预设数量。此时，网络设备通过指示终端设备进行邻区测量，可以使得该终端设备根据邻区测量结果确定合适的邻区(如负载较小的邻区)，并通过RRC连接重建接入至该邻区。需要说明的是，针对不同的小区，预设负载和预设数量可以相同，也可以不同。例如，对于接入设备的上限数量不同的小区，预设数量可以不同。还需要说明的是，预设负载和预设数量均可以由网络配置(例如，在系统消息或专有信令中下发)，或者可以由协议约定，或者可以由终端设备默认设置，或者可以由用户设置以及更改，本申请实施例对此不做限定。
该服务小区的调度情况信息可以反映该服务小区的信道质量。在一种实现方式中，该服务小区的调度情况信息可以包括由该服务小区对应的网络设备配置的RRC最大重复次数。网络设备可以根据小区的信道质量的变化情况，为该小区配置该RRC最大重复次数。可选的，在小区的信道质量变差的情况下，网络设备可以为该小区配置更大的RRC最大重复次数；在小区的信道质量变好的情况下，网络设备可以为该小区配置更小的RRC最大重复次数。在一种实现方式中，若该RRC最大重复次数大于第一预设次数，则该网络设备可以确定该服务小区满足第一预设条件，即可以确定该终端设备需要进行邻区测量。若该RRC最大重复次数小于或等于该第一预设次数，则该网络设备可以确定该服务小区不满足第一预设条件，即可以确定该终端设备无需进行邻区测量。
在另一种实现方式中，该服务小区的调度情况信息可以包括下行控制信息(downlink control information，DCI)中指示的重复次数。可选的，网络设备可以根据小区的信道质量的变化情况，从次数范围内选择该重复次数，并通过DCI指示该重复次数。在小区的信道质量变差的情况下，网络设备可以选择较大的重复次数；在小区的信道质量变好的情况下，网络设备可以选择较小的重复次数。其中，该次数范围可以由该网络设备预先设置。在一种实现方式中，若DCI中指示的重复次数大于第二预设次数，则该网络设备可以确定该服务小区满足第一预设条件，即可以确定该终端设备需要进行邻区测量。若DCI中指示的重复次数小于或等于该第二预设次数，则该网络设备可以确定该服务小区不满足第一预设条件，即可以确定该终端设备无需进行邻区测量。其中，DCI由物理下行控制信道(physical downlink control channel，PDCCH)承载，DCI还可以用于指示上下行资源分配、混合自动重传请求(hybrid automatic repeat request，HARQ)信息、功率控制等。PDCCH是一种物理信道，用于承载下行调度信息。需要说明的是，前述第一预设次数、第二预设次数均可以由网络配置(例如，在系统消息或专有信令中下发)，或者可以由协议约定，或者可以由终端设备默认设置，或者可以由用户设置以及更改，本申请实施例对此不做限定。
在一种实现方式中，终端设备可以对服务小区进行测量，得到该服务小区的信道质量 信息；根据测量得到的该服务小区的信道质量信息，判断该服务小区的信道质量信息是否满足第一预设条件；并在该服务小区的信道质量信息满足第一预设条件的情况下，向该服务小区对应的网络设备发送第二指示信息，该第二指示信息用于指示该服务小区的信道质量信息满足该第一预设条件。相应的，网络设备在接收到来自该终端设备的第二指示信息时，即可确定该服务小区的信道质量信息满足第一预设条件。
邻区测量配置参数是网络设备为终端设备配置的、在进行邻区测量时所需使用的参数。该邻区测量配置参数可以用于指示时长、周期、时间提前量(timing advance，TA)、起始位置中的一种或多种。该邻区测量配置参数所指示的信息(即时长、周期、TA和起始位置中的一种或多种)可以用于确定网络设备针对邻区测量所配置的时域资源。例如，时长和/或周期可以用于确定针对邻区测量所配置的时域资源。
需要说明的是，网络设备可以为终端设备配置进行一次邻区测量所需的时域资源，也可以为该终端设备配置进行多次邻区测量所需的一系列时域资源。还需要说明的是，网络设备为终端设备配置有一系列时域资源的情况下，该网络设备可以指示该终端设备根据该一系列时域资源中的一个时域资源进行一次邻区测量，或者，该网络设备可以指示该终端设备根据该一系列时域资源中的部分或者全部时域资源进行多次邻区测量。所配置的一个时域资源可以看做是进行邻区测量的一次测量时机。
其中，该时长可以指针对邻区测量所配置的时域资源持续的时长。起始位置指针对邻区测量所配置的时域资源的起始位置。例如，起始位置为系统帧中的某子帧。结合时长和起始位置可以确定一个时域资源。若一系列时域资源中相邻的两时域资源的起始位置之间的间隔时长相同，该间隔时长即为周期。可选的，在邻区测量配置参数未指示周期的情况下，可以认为该邻区测量配置参数指示该终端设备进行一次邻区测量；在邻区测量配置参数指示了周期的情况下，可以认为该邻区测量配置参数指示该终端设备进行周期性邻区测量。
因存在距离引起的射频传输时延，TA是指为使终端设备发送的上行包在希望的时间到达网络设备，提前相应时间发出该上行包。TA可以看做是终端设备接收到下行子帧的起始时间与传输上行子帧的时间之间的一个负偏移(negative offset)。网络设备通过适当地控制每个终端设备的偏移，可以控制来自不同终端设备的上行信号到达该网络设备的时间。例如，对于离该网络设备较远的终端设备，由于有较大的传输延迟，需要比离该网络设备较近的终端设备提前发送上行数据。
在一种实现方式中，邻区测量配置参数除了可以用于指示时长、周期、时间提前量(timing advance，TA)、起始位置中的一种或多种以外，还可以用于指示测量次数。该测量次数可以用于指示终端设备进行邻区测量的次数。需要说明的是，在该测量次数为多次的情况下，进行所述多次邻区测量所使用的多个时域资源可以具有周期性的特征，也可以不具有周期性的特征，本申请实施例对此不做限定。具体的，当进行所述多次邻区测量所使用的多个时域资源不具有周期性的特征时，可以通过邻区测量配置参数确定各次邻区测量所对应的时域资源。其中，多个时域资源具有周期性的特征可以指：该多个时域资源的起始位置具有周期性规律；或者，该多个时域资源的持续时长相同，且起始位置具有周期性规律。另外，在测量次数为一次的情况下，无论邻区测量配置参数是否指示了周期，都 可以认为该邻区测量配置参数指示该终端设备进行一次邻区测量。
在一种实现方式中，第一指示信息具体可以用于指示终端设备根据该邻区测量配置参数进行一次邻区测量。此时，根据该邻区测量配置参数指示的信息(即时长、周期、TA和起始位置中的一种或多种)所确定的针对邻区测量所配置的时域资源的数量可以为一个或多个。若终端设备根据该邻区测量配置参数进行一次邻区测量之后，后续还需要进行邻区测量，该网络设备可以再次向该终端设备发送第一指示信息以指示该终端设备再进行一次邻区测量。可选的，第一指示信息用于指示终端设备根据该邻区测量配置参数进行一次邻区测量可以指：指示该终端设备在一时间段内进行一次邻区测量，或者，指示该终端设备在接收到该第一指示信息之后经过多长时间开始进行一次邻区测量。
在另一种实现方式中，该第一指示信息具体可以用于指示终端设备根据邻区测量配置参数进行周期性邻区测量。此时，根据该邻区测量配置参数指示的信息，所确定的针对邻区测量所配置的时域资源的数量为多个，且该多个时域资源具有周期性的特征。通过这种方式，网络设备向终端设备发送一次第一指示信息，即可指示终端设备进行多次邻区测量，有利于节省信令资源。
需要说明的是，该邻区测量配置参数可以携带于第一指示信息中发送给终端设备，也可以由协议约定，还可以由网络设备为终端设备配置(例如，在专有信令中为终端设备配置)，本申请实施例对此不做限定。还需要说明的是，邻区测量配置参数可以由该终端设备当前的服务小区对应的网络设备配置，也可以由该终端设备的历史服务小区对应的网络设备配置。通过这种方式，为终端设备配置一次邻区测量配置参数后，可以在不同的小区内使用，而不用针对每个小区重新进行配置，有利于节省信令资源。在一种实现方式中，在用于配置邻区测量配置参数的网络设备与(终端设备当前的)服务小区对应的网络设备不同的情况下，前述第二指示信息可以包括该邻区测量配置参数。终端设备在进行邻区测量时，无法接收到该终端设备的服务小区对应的网络设备发送的信息。若用于配置邻区测量配置参数的网络设备与该服务小区对应的网络设备不同，那么该服务小区对应的网络设备无法获知该终端设备中配置的邻区测量配置参数，也就无法获知该终端设备在何时进行邻区测量。这样可能会发生如下情况：该服务小区对应的网络设备在该终端设备进行邻区测量的过程中向该终端设备发送信息，这样会导致该终端设备无法接收到该信息，该信息丢失。在此情况下，本申请实施例通过在第二指示信息中携带终端设备中配置的邻区测量配置参数，可以使得该服务小区对应的网络设备可以获取该邻区测量配置参数，从而有利于避免该终端设备与网络设备的通信与该终端设备的邻区测量产生冲突。
在一种实现方式中，该终端设备的服务小区可以和历史服务小区交互以获得该邻区测量配置参数。可选的，该服务小区对应的网络设备可以向该历史服务小区对应的网络设备发送参数请求，以请求获取该邻区测量配置参数。可选的，该历史服务小区对应的网络设备可以主动向该服务小区对应的网络设备发送该邻区测量配置参数。其中，该历史服务小区对应的网络设备可以为前述用于配置邻区测量配置参数的网络设备。
在一种实现方式中，网络设备还可以通过RRC重配流程为终端设备配置邻区测量配置参数，或者在除第一指示信息以外的其他信息中向终端设备下发邻区测量配置参数。终端设备更换小区后，若未配置有邻区测量配置参数，则网络设备可以通过RRC重配流程为该 终端设备配置邻区测量配置参数；若该终端设备已经配置有邻区测量配置参数，则可以采用已经配置的邻区测量配置参数进行邻区测量。这样可以节省更换小区后进行RRC重配的信令资源。
在本申请实施例中，在终端设备已配置有邻区测量配置参数的情况下，网络设备通过向终端设备发送第一指示信息以指示该终端设备根据该邻区测量配置参数进行邻区测量。在此过程中，该第一指示信息可以看做用于激活邻区测量配置参数。换言之，为终端设备配置邻区测量配置参数之后，该邻区测量配置参数并非立刻生效(即终端设备在此时不会采用该邻区测量配置参数进行邻区测量)，而是在接收到第一指示信息之后才生效。
在一种实现方式中，第一指示信息可以携带于媒体接入控制-控制单元(medium access control control element，MAC CE)中，或者可以携带于MAC协议数据单元(protocol data unit，PDU)子头中，或者可以携带于其他信息(如DCI)中，本申请实施例对此不做限定。终端设备更换小区后，相较于通过RRC重配流程重新为该终端设备配置邻区测量配置参数，本申请实施例通过MAC CE(或MAC PDU子头)携带的第一指示信息激活邻区测量配置参数，有利于更加灵活的触发和停止邻区测量，且有利于节省信令资源。
在一种可选的实施方式中，所述第一指示信息可以是网络设备通过以下方式发送的：
方式1、该第一指示信息可以携带于MAC CE发送，其中，可以通过MAC CE中的逻辑信道号(logical channel ID，LCID)字段为特定值时指示终端设备根据邻区测量配置参数进行邻区测量。例如，表1所示的MAC CE的结构中，可以通过对当前标准新增定义LCID为10001，以用于指示终端设备根据邻区测量配置参数进行邻区测量，或者可以通过其他比特值，例如当前标准中未被定义的数值(例如预留数值)，来指示终端设备进行邻区测量，本申请对此不作限制。
表1
R F2 E LCID
或者，该第一指示信息可以通过MAC PDU子头发送，其中，可以通过MAC PDU子头中的LCID字段为特定值时指示终端设备根据邻区测量配置参数进行邻区测量。例如，表2所示的MAC PDU子头的结构中，当LCID为特定值01011或01111或其他比特值时，指示终端设备根据邻区测量配置参数进行邻区测量。
表2
R F2 E LCID
方式2、该第一指示信息可以携带于MAC CE发送，其中，可以通过MAC CE中的LCID字段为特定值时指示终端设备根据邻区测量配置参数进行邻区测量。例如，表3所示的MAC CE的结构中，可以通过对当前标准新增定义LCID索引值(index)为33或46或其他索引值，以用于指示终端设备根据邻区测量配置参数进行邻区测量。
表3
R R LCID
或者，该第一指示信息可以通过MAC PDU子头发送，其中，可以通过MAC PDU子头中的LCID字段为特定值时指示终端设备根据邻区测量配置参数进行邻区测量。例如，表4所示的MAC PDU子头的结构中，LCID index为33或46或其他索引值时指示终端设 备根据邻区测量配置参数进行邻区测量。
表4
R R LCID
方式3、该第一指示信息可以通过MAC PDU子头发送，其中，可以通过MAC PDU子头中的F2字段为特定值时指示终端设备根据邻区测量配置参数进行邻区测量。例如，表2所示的MAC PDU子头的结构中，当F2为特定值1或其他值时用于指示终端设备根据邻区测量配置参数进行邻区测量。
方式4、该第一指示信息可以通过MAC PDU子头发送，其中，可以通过MAC PDU子头中的R字段为特定值时指示终端设备根据邻区测量配置参数进行邻区测量。
例如，表2所示的MAC PDU子头的结构中，当R为特定值1或其他值时用于指终端设备根据邻区测量配置参数进行邻区测量。
或者，例如表4所示的MAC PDU子头的结构中，当R为特定值1或其他值时用于指示终端设备根据邻区测量配置参数进行邻区测量。
方式5、该第一指示信息可以通过MAC PDU子头发送，其中，可以通过MAC PDU子头中的F字段为特定值时指示终端设备根据邻区测量配置参数进行邻区测量。例如，表5所示MAC PDU子头的结构中，当F为特定值1或其他值时用于指示终端设备根据邻区测量配置参数进行邻区测量。
表5
Figure PCTCN2021102971-appb-000001
或者，例如表6所示MAC PDU子头的结构中，当F为特定值1或其他值时用于指示终端设备根据邻区测量配置参数进行邻区测量。
表6
Figure PCTCN2021102971-appb-000002
需要说明的是，当MAC PDU的有效负荷(payload)不为0时(即L的值不为0)，还可以在payload中携带指示终端设备进行邻区测量的辅助信息，例如，待测邻区的小区标识。
作为一种示例，在表1、表2、表5所示的MAC CE及MAC PDU子头的结构中，L字段指示相应的MAC业务数据单元(service data unit，SDU)或可变大小的MACCE的长度，单位为字节；F2字段和F字段联合指示L字段的大小；E字段指示MAC头中是否存在更多字段；R字段表示预留比特。在表3、表4、表6所示的MAC CE及MAC PDU子头的结构中，L字段指示相应的MAC业务数据单元(service data unit，SDU)或可变大小的MACCE的长度，单位为字节；F字段指示L字段的大小；R字段表示预留比特。
在一种实现方式中，网络设备还可以向终端设备发送第三指示信息，该第三指示信息可以用于指示该终端设备停止邻区测量。换言之，该第三指示信息用于去激活(disable)邻区测量配置参数。进行邻区测量会增加终端设备的功耗，且测量的邻区越多，增加的功耗越显著。网络设备通过发送第三指示信息，可以避免该终端设备一直进行邻区测量，从 而有利于降低该终端设备的功耗。
在一种实现方式中，网络设备可以在确定终端设备的服务小区满足第三预设条件的情况下，向该终端设备发送第三指示信息。终端设备的服务小区满足第三预设条件可以表示：该服务小区的信道质量较好。换言之，该终端设备在当前的信道状态下与该服务小区保持通信，使得终端设备可以保持通信业务的正常运行；或者，该终端设备不需要继续进行邻区测量；或者，该终端设备不需要更换小区。通过这种方式，在服务小区的信道质量较好的情况下向终端设备发送第三指示信息，可以避免该终端设备进行不必要的邻区测量或者在不必要时更换小区，从而有利于降低该终端设备的功耗。
在一种实现方式中，网络设备可以通过如下方式确定终端设备的服务小区满足第三预设条件：
方式1：网络设备获取以下参数中的至少一项：参考信号接收功率RSRP、参考信号接收质量RSRQ、信号与干扰加噪声比SINR、信噪比SNR、成功接收重复次数、重复发送次数、覆盖增强等级、发射功率、下行无线链路误块率、以特定误块率可靠接收假设的PDCCH的链路水平、该服务小区的覆盖中心与该终端设备之间的距离、该服务小区的负载或该服务小区的调度情况信息，并根据所获取的信息判断该服务小区是否满足第三预设条件。可选的，终端设备上报服务小区的参考信号接收功率RSRP，若网络设备确定该终端设备的服务小区的参考信号接收功率高于预设参考信号接收功率阈值，则该网络设备可以确定该终端设备的服务小区满足第三预设条件。可选的，该服务小区的调度情况信息可以包括由该服务小区对应的网络设备配置的RRC最大重复次数或DCI中指示的重复次数，若该RRC最大重复次数小于或等于前述第一预设次数，则该网络设备可以确定该服务小区满足第三预设条件；若DCI中指示的重复次数小于或等于前述第二预设次数，则该网络设备可以确定该服务小区满足第三预设条件。可选的，若该服务小区的覆盖中心与该终端设备之间的距离未超过前述预设距离阈值，则该网络设备可以确定该服务小区满足第三预设条件。可选的，若该服务小区的负载小于或等于前述预设负载，则该网络设备可以确定该服务小区满足第三预设条件。服务小区的负载小于或等于预设负载可以指：接入该服务小区的终端设备的数量大于预设数量。
方式2：网络设备接收来自终端设备的第四指示信息，该第四指示信息可以用于指示该终端设备的服务小区满足第三预设条件。在一种实现方式中，终端设备可以对服务小区进行测量，得到该服务小区的信道质量信息(如信道质量参数的评估值)；根据测量得到的该服务小区的信道质量信息，判断该服务小区的信道质量信息是否满足第三预设条件；并在该服务小区的信道质量信息满足第三预设条件的情况下，向该服务小区对应的网络设备发送该第四指示信息。例如，若该服务小区的信道质量参数(参见步骤S201的具体描述)的评估值大于第六预设阈值，终端设备可以确定该服务小区的信道质量信息满足第三预设条件。该服务小区的信道质量参数的评估值大于第六预设阈值，可以表明该服务小区的信道质量足够好。
需要说明的是，第三预设条件与第六预设阈值均可以由网络配置(例如，在系统消息或专有信令中下发)，或者可以由协议约定，或者可以由终端设备默认设置，或者可以由用户设置以及更改，本申请实施例对此不做限定。
还需要说明的是，第三指示信息可以携带于MAC CE中，或者可以携带于MAC PDU子头中，或者可以携带于其他信息(如DCI)中，本申请实施例对此不做限定。在MAC CE(或MAC PDU子头)中携带第三指示信息的方式，与在MAC CE(或MAC PDU子头)中携带第一指示信息的方式类似，具体可以参照前文表1-表6相应内容，此处不再赘述。
在一种实现方式中，在步骤S401或者S401之前，网络设备还可以获取终端设备的能力信息，该能力信息可以用于指示该终端设备是否具有在检测到RLF之前进行RRC连接重建的能力。该能力信息可以是由终端设备发送给网络设备的，也可以是服务小区的网络设备通过与历史服务小区的网络设备交互获得的。可选的，该能力信息可以是显式的，例如，该能力信息可以指示该终端设备具有在检测到RLF之前进行RRC连接重建的能力，或者，该能力信息可以指示该终端设备支持在RRC连接态进行邻区测量。可选的，该能力信息也可以是隐式的，例如，若网络设备接收到终端设备发送的第二指示信息，或者，若服务小区的网络设备通过与历史服务小区的网络设备交互，获得了该终端设备的邻区测量配置参数，则认为该终端设备具有在检测到RLF之前进行RRC连接重建的能力，或者，该终端设备支持在RRC连接态进行邻区测量。此时，该网络设备可以在前述服务小区满足第一预设条件的情况下，向该终端设备发送第一指示信息；该第一指示信息可以用于指示该终端设备在检测到RLF之前，根据邻区测量配置参数进行邻区测量。在该服务小区满足第三预设条件的情况下，网络设备可以向该终端设备发送第三指示信息，以指示该终端设备停止进行邻区测量。
在一种实现方式中，在步骤S401或者S401之前，网络设备还可以确定终端设备是否开启如下功能：在检测到RLF之前进行RRC连接重建，或者支持在RRC连接态进行邻区测量。终端设备是否开启该功能可以由该终端设备以显式或隐式的方式告知该网络设备。例如，终端设备可以向该网络设备发送一指示信息，该指示信息可以指示该终端设备是否开启该功能。或者，若网络设备接收到终端设备发送的前述第四指示信息，则可以认为该终端设备已开启该功能。此时，该网络设备可以在前述服务小区满足第一预设条件的情况下，向该终端设备发送第一指示信息，以指示该终端设备在检测到RLF之前，根据邻区测量配置参数进行邻区测量。在该服务小区满足第三预设条件的情况下，网络设备可以向该终端设备发送第三指示信息，以指示该终端设备停止进行邻区测量。
步骤S402：终端设备在处于无线资源控制RRC连接态的情况下，根据该邻区测量配置参数，对该服务小区的多个邻区进行测量，得到邻区测量结果；该邻区测量结果包括该多个邻区的信道质量信息。
具体的，终端设备接收到来自该服务小区对应的网络设备的第一指示信息时，可以确定此时该服务小区满足第一预设条件，即可以确定该终端设备需要进行邻区测量。终端设备根据邻区测量配置参数对该服务小区的多个邻区进行测量的具体实施方式可以为：终端设备根据邻区测量配置参数确定针对邻区测量所配置的时域资源，进而在该时域资源上对该服务小区的多个邻区进行测量。
步骤S403：该终端设备在检测到无线链路失败RLF之前，根据该邻区测量结果，发起针对前述多个邻区中的目标邻区的RRC连接重建过程。
需要说明的是，步骤S403的执行过程可参见图2中步骤S202或者图3中步骤S302 的具体描述，此处不再赘述。
通过实施本申请实施例，在终端设备的服务小区满足第一预设条件的情况下，网络设备通过向该终端设备发送第一指示信息以指示该终端设备进行邻区测量，有利于该终端设备更及时地获取邻区测量结果，进而有利于更及时地确定合适的目标邻区进行RRC连接重建，降低对终端设备的业务造成的影响。
