具体实施方式
为了方便理解本申请实施例的技术方案，首先给出本申请相关技术的简要介绍如下。
1.D2D通信、侧行链路、U2N relay通信：
D2D通信：或称为邻近服务(proximity service，ProSe)，是指终端和终端之间的直连通信，数据不经过网络中转。
侧行链路：是为了支持D2D通信引入的区别于上行链路和下行链路的链路，又称为直通链路或侧链，其对应的接口称为PC5接口。
在U2N relay通信中，运营商可以部署中继终端(relay终端)，为远端终端(remote终端)中转数据。也就是说，远端终端通过中继终端与网络设备通信，例如，远端终端有待发送给网络设备的数据到达时，远端终端向中继终端发送该数据，中继终端收到该数据后，向网络设备转发该数据。可以理解的是，在U2N relay通信中，远端终端和中继终端之间的通信为D2D通信，或者说，远端终端和中继终端通过侧行链路通信。
2.直接通信(direct communication)、非直接通信(indirect communication)：直接通信：指终端和网络之间没有终端到网络的中继节点(例如中继终端)的通信。
非直接通信：指终端和网络之间有终端到网络的中继节点(例如中继终端)的通信。
在一些实施方式中，本申请中的直接通信也可以称为直连通信或直接网络通信；本申请中的非直接通信也可以称为非直连通信或非直接网络通信或间接通信，可以相互替换。
3.移动历史信息报告：
传统的蜂窝网络中，终端在移动过程中，若支持移动历史信息报告的测量、存储与上报，将会记录终端所访问的小区的标识信息和在该小区内的停留时长。此外，还可以记录终端处于无小区覆盖(out of coverage，OoC)状态的持续时长。
一般来说，在终端进行小区切换时，终端记录切换前的服务小区的标识信息以及在该服务小区内的驻留时长。在终端从OoC状态切换至小区驻留状态时，记录本次OoC的持续时长，但不记录任何标识。
示例性的，如图3所示，假设终端从左至右依次穿过小区1至小区4的覆盖区域，且在小区3和小区4之间经历了OoC状态。在终端从小区1切换至小区2的情况下，终 端记录的移动性历史报告为{小区1的标识，在小区1驻留的时长}；在终端从小区2切换至小区3的情况下，终端记录的移动性历史报告为{小区2的标识，终端在小区2驻留的时长}；在终端从小区3切换至OoC状态的情况下，终端记录的移动性历史报告为{小区3的标识，在小区3驻留的时长}；在终端从OoC状态切换至小区4的情况下，终端记录的移动性历史报告为{OoC状态的持续时长}。
4.无线资源控制(radio resource control，RRC)连接建立失败(connection establishment failure，CEF)和RRC连接恢复失败(connection resume failure，CRF)：
为了检测RRC连接建立成功与否，终端在向网络设备发送RRC建立请求消息时，启动定时器T300，并根据定时器T300进行相应处理，例如：
在T300到期前，终端收到RRC建立消息或RRC拒绝消息或终端上层指示终端该RRC连接建立流程的情况下，终端停止T300，并进行相应的后续流程，例如，在收到RRC建立消息的情况下，进行连接建立准备工作，并发送RRC建立完成消息。
在T300到期时，终端未收到网络设备回复的RRC消息，例如RRC建立消息，也未收到终端上层的终端指示的情况下，终端确定发生CEF，并记录CEF的相关测量信息。其中，CEF的相关测量信息可参考相关标准中的定义，在此不再赘述。
此外，为了检测RRC连接恢复成功与否，终端在向网络设备发送RRC恢复请求消息时，启动定时器T319，并根据定时器T319判断是否发生CRF，在发生CRF的情况下，记录CRF相关的测量信息。其中，CRF相关的测量信息包括的内容与CEF相关的测量信息包括的内容相同，可参考上述相关说明，在此不再赘述。
对于上述介绍的移动历史信息报告以及CEF和CRF相关的测量信息，在一些场景下可能存在如下问题：
示例性的，对于移动历史信息报告：
一种可能的实现方式中，在U2N relay通信场景下，远端终端由中继终端的服务小区控制。因此，远端终端进行非直接通信时，其小区驻留情况以及对于移动历史信息的感知和测量将与直接通信有所差别，从而导致网络设备估计的远端终端的移动性产生偏差。
示例性的，如图4所示，假设终端1在黑色粗实线表示的轨迹上从A点移动至B点，期间穿过小区1和小区2，在C点通过终端2从小区1切换至小区2，在B点由小区2切换至OoC状态。
一种可能的移动历史信息报告的记录方法中，终端1感知到的小区1的覆盖范围为图4所示的斜线填充的区域(称为区域1)，小区2的覆盖区域为图4所示的菱形填充的区域(称为区域2)，即终端1记录并上报的移动历史信息报告包括{小区1的标识，区域1驻留的时长}以及{小区2的标识，区域2的驻留时长}。
该情况下，终端1上报的区域1驻留的时长小于实际在小区1内驻留的时长，从而网络设备根据该信息估计的终端1的移动速度可能大于实际速度；终端2上报的区域2驻留的时长大于实际在小区2内驻留的时长，从而网络设备根据该信息估计的终端1的移动速度可能小于实际速度。此外，小区1和小区2之间实际存在OoC区域，但是终端1并未感知。
示例性的，对于接入性失败报告：
如图5所示，为U2N relay通信场景中，远端终端与网络设备进行RRC连接建立的流程示意图，包括如下步骤：
S501、远端终端通过发现(discovery)过程选择合适的中继终端。
需要说明的是，本申请以远端终端选择的中继终端已经建立了与网络设备之间的RRC连接为例进行说明。
S502、远端终端和中继终端建立PC5-RRC连接。
S503和S504、远端终端通过中继终端，向网络设备发送RRC建立请求消息。
S505和S506、网络设备通过中继终端，向远端终端回复RRC建立消息。
S507和S508、远端终端通过中继终端，向网络设备发送RRC建立完成消息。
其中，上述步骤S503至S506中的任一RRC消息发送不成功，远端终端都将感知到CEF，但是远端终端无法感知CEF发生在侧行链路还是中继终端与网络设备之间的链路(以下称为Uu接口对应的链路)，从而导致网络设备无法识别CEF是发生在侧行链路还是Uu接口对应的链路上，进而网络无法根据测量上报信息确定合适的网络优化方案。例如，当远端终端和中继终端之间的侧行链路不稳定，远端终端未能成功发送S503的RRC建立请求消息时，将检测到CEF并进行测量上报。网络设备接收到测量信息后，可能会误认为这是Uu接口对应的链路上的信号质量问题导致的CEF，从而选择优化本小区内的网络信号质量。然而，该决策实质上并不能对上述CEF进行优化。
另外，RRC连接恢复流程中存在与RRC连接建立过程中类似的问题，可参考上述相关说明，在此不再赘述。
基于此，本申请提供一种测量上报方法，可以降低网络设备对终端的移动性估计误差，提高移动性估计的准确性。此外，在发生RRC连接建立失败或RRC连接恢复失败的情况下，增强失败相关的测量报告，从而提高网络设备根据该测量报告进行网络优化的准确性和合理性，提高网络优化效率。

关于本实施例中第一测量报告包括的内容：
其中，第一测量报告包括第一指示信息，该第一指示信息指示第一终端的通信模式，该通信模式包括直接通信、非直接通信、或无覆盖状态。无覆盖状态也可以称为无覆盖模式，该状态下，终端所处的位置无小区覆盖，终端未驻留在任何小区。

第一切换前第一终端的通信模式；
第一切换后第一终端的通信模式；

在一些实施方式中，该第一指示信息可以包括第一指示符，该第一指示符的不同取值可以用于指示不同的通信模式。
在第一指示信息用于指示第一切换前第一终端的通信模式，以及，第一切换后第一终端的通信模式的情况下：
作为一种示例，该第一指示符可以是1比特的indicator，该第一指示符的取值为第一数值时，指示第一情况。该第一情况可以是：第一切换前第一终端的通信模式以及第一切换后第一终端的通信模式不包括非直接通信，例如，第一切换前第一终端的通信模式和第一切换后第一终端的通信模式中，一个为直接通信，另一个为OoC状态。该第一指示符的取值为第二数值时，指示除第一情况外的其他情况，也就是说，第一切换前第一终端的通信模式以及第一切换后第一终端的通信模式包括非直接通信，例如，第一切换前第一终端的通信模式和第一切换后第一终端的通信模式中，一个为直接通信，另一 个为非直接通信。

可选的，该测量报告可以是第一终端根据第一小区的信号质量确定的。即在步骤S1501之前，该方法还可以包括：
S1500、第一终端根据第一小区的信号质量，确定测量报告。
示例性的，如图16所示，以第一终端为终端1为例，终端1从A点移动至B点的过程中，在C点发生第一切换，从小区1的直接通信切换至小区2的非直接通信，若终端1在D点首次测得小区1的信号质量大于第一阈值，则第一时刻为终端1位于D点的时刻，若在E点首次测得小区1的信号质量小于或等于第一阈值，则第二时刻为终端1位于E点的时刻，第一时长即为终端1从D点移动至E点的时长，在该时长内，终端1穿过了完整的小区1。在C点小区1的信号质量可能大于第一阈值，此时终端1在C点发生第一切换的原因可能是小区2的信号质量大于小区1的信号质量。
可选的，该第一小区的信号质量可以是第一终端对第一小区进行测量得到的，即该方法还可以包括：第一终端对第一小区进行测量，得到第一小区的信号质量。
可选的，第一终端对第一小区进行测量，可以为：第一终端对第一小区进行Uu口的小区测量，例如，测量第一小区的参考信号。
可选的，第一终端可以周期性或非周期性连续对第一小区进行测量，每次测量得到一个第一小区的信号质量。示例性的，小区的信号质量可以包括(reference signal Received Power，RSRP)、参考信号接收质量(reference signal received quality，RSRQ)、或信号与干扰噪声比(signal to interference plus noise ratio，SINR)中的一项或多项。
基于该方案，终端通过小区测量确定移动历史信息，使得测量报告可以反映终端在一个完整的小区内的驻留时长，从而降低非直接通信的引入对终端移动性估计的误差，提高网络设备对终端进行移动性管理的效率。
上述提供的方法对终端移动性相关的测量报告进行了说明。下面，对终端的RRC连接失败相关的测量报告进行说明。本实施例中，以第一终端通过第二终端与第一网络设备建立或恢复RRC连接的过程中发生RRC连接失败为例进行说明。

可选的，第二终端收到该请求消息时，可以启动第二定时器，该第二定时器可以用于监测第二终端与第二网络设备之间是否发生RRC连接失败。
可选的，第一定时器的时长大于第二定时器的时长。基于该方案，可以避免第一终端通过第二终端收到第一网络设备对该请求消息的响应之前，确定发生了RRC连接失败。
S1702、第二终端向第一网络设备发送该请求消息。相应的，第一网络设备接收该请求消息。
可选的，第二终端在收到第一终端的该请求消息时，未启动第二定时器的情况下，可以在向第一网络设备发送该请求消息时，启动第二定时器。

其中，该第二消息为第一网络设备对该请求消息的响应消息，也就是说，该第二消息为该请求消息对应的响应消息，或者说，第二消息用于响应该请求消息。
示例性的，第二消息可以为以下任意一种：

第一小区的跟踪区域码(tracking area code，TAC)，用于指示第一小区的跟踪区域(tracking area，TA)；

连续发生RRC连接失败的次数，以RRC连接失败为CEF为例，在发生本次CEF之前，若第二终端已经记录了之前发生过的CEF的相关测量信息，并且当前的注册移动网络，和之前记录的移动网络不一致或当前所处小区标识和之前记录的小区标识不一致，该连续CEF次数的值设置为0；否则，若之前记录的该连续CEF次数的值小于8，将之前记录的取值加1作为本次记录的连续CEF的次数；其中，移动网络例如可以为PLMN；

可选的，该第一消息还包括第三指示信息，该第三指示信息用于指示第二链路上发生RRC连接失败。
需要说明的是，本实施例提供的测量上报方法还涉及“第二指示信息”，将在下文说明，在此不予赘述。
可选的，第二终端在发送第一消息后，若收到来自第一终端的第三反馈信息，反馈 第一终端成功接收该第一消息，第二终端可以删除第一消息包括的RRC连接失败的相关信息中除第一移动网络标识外的其他信息。
针对上述图17所示的流程，示例性的，可以执行如图18所示的方法进行测量上报。参见图18，该测量上报方法包括如下步骤：
S1801、第一终端确定第三测量报告。
其中，该第三测量报告包括第二指示信息。该第二指示信息用于指示发生RRC连接失败的链路。可以理解的，发生RRC连接失败的链路为图17所示方法中的第一链路或第二链路。
可选的，该第三测量报告可以用于网络优化。在一些实现方式中，本实施例中的第三测量报告也可以称为接入性失败报告或接入性失败信息，可以相互替换。当然，该第三测量报告也可以有其他名称，本申请对此不作具体限定。
可选的，第一终端确定第三测量报告，也可以理解为：第一终端记录该第三测量报告，或者，第一终端生成该第三测量报告，或者，第一终端获取该第三测量报告，可以相互替换。
作为一种实现方式，在第二指示信息指示发生RRC连接失败的链路为第一链路的情况下，该第三测量报告还可以包括以下一项或多项：
第二终端的标识；
第一小区的标识；
至少一个第三终端的信息，示例性的，该第三终端的信息可以包括第三终端的标识，和/或，第一终端和第三终端之间的链路对应的信道质量信息；
第一链路对应的信道质量信息；
第一小区的跟踪区域码；
第一移动网络的标识；
第三小区的信号质量信息，第三小区可以在第一终端能够测量到的小区；
第一链路上连续发生RRC连接失败的次数，在发生本次RRC连接失败之前，若第一终端已经记录了之前在第一链路上发生过的RRC连接失败的相关信息，并且第一终端当前的注册移动网络和之前记录的移动网络不一致、或第一终端当前对应中继终端和之前记录的中继终端不一致、或第一终端当前对应的中继终端所处的小区的标识和之前记录的中继终端所处的小区的标识不一致，该第一链路上连续发生RRC连接失败的次数设置为0；否则，若之前记录的第一链路上连续发生RRC连接失败的次数的值小于8，将之前记录的取值加1作为本次报告的第一链路上连续发生RRC连接失败的次数。
可选的，第三终端可以是第一终端周边能够作为中继终端的终端，或者说，第三终端可以是备选(或后续)的中继终端。
作为另一种实现方式，在第二指示信息指示发生RRC连接失败的链路为第二链路的情况下，该第三测量报告还可以包括第二终端的标识和第二终端记录的RRC连接失败的相关信息。
可选的，在该步骤S1801之前，第一终端可以通过其是否收到第一消息或第二消息确定是否发生RRC连接失败，在发生RRC连接失败的情况下，可以进一步确定RRC连接失败发生的链路。其中，判断是否发生RRC连接失败也可以理解为确定发生RRC连接失败或未发生RRC连接失败。
示例性的：
在第一终端收到第一消息的情况下，第一终端确定第二链路上发生了RRC连接失败。进一步的，在第一定时器到期前，第一终端收到第一消息的情况下，确定第二链路上发生RRC连接失败。
在第一终端收到第二消息的情况下，第二终端确定未发生RRC连接失败，后续可以根据第二消息进行相应处理。例如，在第二消息为RRC建立消息时，通过第二终端向第一网络设备发送RRC建立完成消息。进一步的，在第一定时器到期前，第一终端收到第二消息的情况下，确定未发生RRC连接失败。
在第一终端未收到第一消息和第二消息的情况下，第一终端确定第一链路上发生RRC连接失败。进一步的，在第一定时器到期前，第一终端未收到第一消息和第二消息的情况下，确定第一链路上发生RRC连接失败。
可选的，第一终端未收到第一消息和第二消息的原因可能是:在上述步骤S1701中，由于第一链路的质量较差，第二终端未收到第一终端发送的请求消息，从而后续操作不会执行，也就是说，S1702-S1704a或S1702-S1704b不会执行，进而第一终端无法收到第一消息和第二消息，此时，第一终端也可以确定第一链路上发生RRC连接失败。
可选的，第一终端收到第一消息的原因可能是：在上述步骤S1702中，由于第二链路的质量较差，第一网络设备未收到第二终端发送的请求消息，从而第一网络设备不会执行S1703，进而第二终端无法收到第二消息，此时，第二终端仍然可以执行上述步骤S1704b，向第一终端发送第一消息，使得第一终端确定第二链路上发生RRC连接失败。
S1802、第一终端向第二网络设备发送该第三测量报告。相应的，第二网络设备接收来自第一终端的第三测量报告。
可选的，第二网络设备和第一网络设备可以是相同的网络设备，也可以是不同的网络设备，本申请对此不作具体限定。
其中，该步骤S1802的实现方式可参考上述步骤S802的相关说明，在此不再赘述。
可选的，第二网络设备还可以向第一终端发送第四反馈信息，用于反馈第二网络设备是否成功第三测量报告。
可选的，在第一终端基于第二网络设备的请求消息发送第三测量报告的情况下，处第三测量报告外，第一终端还可以发送第三报告，该第三报告可以包括第一时间间隔，该第一时间间隔可以为第一终端收到请求消息与上一次发生RRC连接失败之间的时间间隔。示例性的，该第一时间间隔可以携带在timeSinceFilure信元中。
S1803、第二网络设备根据第三测量报告进行通信。
可选的，在第二网络设备和第一网络设备不同的情况下，第二网络设备根据第三测量报告进行通信可以为：第二网络设备向第一网络设备发送第三测量报告，相应的，第一网络设备接收来自第二网络设备的第三测量报告，之后，第一网络设备可以根据第三测量报告进行网络优化。
可选的，在第二网络设备和第一网络设备相同的情况下，第二网络设备根据第三测量报告进行通信，可以包括：第二网络设备根据该第三测量报告进行网络优化。
作为一种可能的实现，网络设备根据第三测量报告进行网络优化时，若第三测量报告包括的第二指示信息指示第二终端和第一网络设备之间的链路发生RRC连接失败，网络设备可以增强第二终端所处小区的覆盖优化Uu接口的信号质量以优化网络覆盖。
或者，网络设备可以根据第二指示信息确定第二终端和第一网络设备之间的链路发生RRC连接失败，并确定发生该RRC连接失败的原因可能是第二终端与第一网络设备 之间的链路质量较差，即第二终端可能不适合作为中继终端。由于终端是否可以作为中继终端的条件可以是：终端与第一网络设备之间的链路质量大于第二阈值且小于第三阈值(第三阈值大于第二阈值)，因此第二终端作为中继终端的原因可能是第二阈值的取值过低，从而网络设备可以提高该第二阈值的取值，以提高对中继终端的要求。
或者，在第三测量报告包括本次RRC连接失败相关的随机接入信息时，网络设备可以根据该随机接入信息优化随机接入的参数。
或者，在第三测量报告包括连续发生RRC连接的次数时，若该次数较多，可以指示第一终端切换至信号质量较好的小区或信号质量较好小区的中继终端。
作为另一种可能的实现，网络设备根据第三测量报告进行网络优化时，若第三测量报告包括的第二指示信息指示第一终端和第二终端之间的链路发生RRC连接失败，在第一终端进行切换时，网络设备可以指示第一终端不再接入第二终端；或者可以指示第二终端在后续的一段时间内不再作为中继终端；或者可以指示第二终端增强其侧行链路的质量。
基于上述方案，一方面，在第一终端通过第二终端与第一网络设备建立或恢复RRC连接的过程中发生RRC连接失败的情况下，第一终端能够识别该RRC连接失败发生的链路是侧行链路还是Uu口对应的链路，并在第三测量报告中指示发生RRC连接失败的链路，从而使得网络设备能够根据该第三测量报告进行合理的网络优化，提高网络优化的效率。另一方面，该第三测量报告中还包括RRC连接失败相关的其他信息，例如第三终端的信息或者第二终端记录的RRC连接失败的相关信息，可以向网络设备提供更多的信息，进一步提高网络优化的合理性及准确性。
此外，本申请还提供一种测量上报方法，如图19所示，该测量上报方法包括如下步骤：

其中，第一终端向第二网络设备发送第三测量报告的方式可参考上述步骤S1802中的相关描述，在此不再赘述。
在一种可能的实现方式中，该第三测量报告是第一终端确定的，因此，在步骤S1901之前，该方法还可以包括：

作为一种实现方式，第一终端确定该第三测量报告也可以理解为第一终端生成该第三测量报告；或者，第一终端获取该第三测量报告；或者，第一终端记录该第三测量报告。本实施例对第一终端确定该第三测量报告的方式不作具体限定。
S1902、第三网络设备根据第三测量报告进行通信。
其中，第三网络设备根据第三测量报告进行通信的实现可参考上述步骤S1803中的相关说明，在此不予赘述。
