Description

测量及上报方法、装置及系统
本申请要求于2021年03月23日提交国家知识产权局、申请号为202110310760.2、申请名称为“测量及上报方法、装置及系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，尤其涉及测量及上报方法、装置及系统。
背景技术
非陆地网络(non-terrestrial network，NTN)指将基站或者部分基站功能部署在高空平台或者卫星上为终端提供无缝覆盖的网络。随着NTN与第五代(5th generation，5G)技术的融合，将地面网络中的移动性管理引入NTN，以使NTN网络优化其覆盖，是未来通信发展的重要方向。
移动性管理是无线通信系统中的重要组成部分，指的是为了保证网络与终端之间的通信链路不因终端的移动而中断所涉及的相关内容的统称。移动性管理根据终端的状态大致上可以分为空闲态移动性管理和连接态移动性管理两部分。在空闲态/去激活态下，移动性管理主要指的是小区选择/重选(cell selection/reselection)的过程，在连接态下，移动性管理主要指的是小区切换(handover)。不论是小区选择/重选还是切换，都是基于测量的结果进行的，因此移动性测量是移动性管理的基础。
目前，地面网络中的测量是基于信号质量的测量，例如测量参考信号接收功率(reference signal receiving power，RSRP)或者参考信号接收质量(reference signal receiving quality，RSRQ)等。但是在NTN中，因为远近效应不明显，小区中心和边缘的信号质量差值不足3dB，因此，基于信号质量的测量可能不再适用于NTN通信。
发明内容
本申请提供一种测量及上报方法、装置及系统，可以提高测量的合理性，提升测量报告对网络设备的价值，从而使得网络设备能够合理地进行网络优化，最终提高用户的服务质量。
为达到上述目的，本申请采用如下技术方案：
第一方面，提供了一种测量及上报方法，该方法可以由终端执行，也可以由终端的部件，例如终端的处理器、芯片、或芯片系统等执行，本申请以终端执行该方法为例进行说明。该方法包括：终端接收用于配置目标小区的测量配置信息，对目标小区进行测量，得到目标小区的测量报告，并发送目标小区的测量报告。其中，目标小区包括服务小区和邻区；测量报告包括第一时间信息和/或第一位置信息，第一时间信息包括以下一项或多项：服务小区的覆盖剩余时间、邻区的覆盖剩余时间、或邻区即将到来的时间；第一位置信息包括：终端所处的位置与服务小区的中心位置之间的距离，和/或，终端所处的位置与邻区的中心位置之间的距离；或者，第一位置信息包括：终端所处的位置与服务小区的边缘位置之间的距离，和/或，终端所处的位置与邻区的边缘位置之间的距离。
基于该方案，本申请基于时间和/或位置进行测量，并向网络设备上报与小区覆盖相关的第一时间信息和/或第一位置信息，在网络设备或终端设备高速移动的远距离通信场景下，如NTN中，相比于单纯基于信号质量的测量以及上报信号质量相关的信息，可以提高测量的合理性，提升测量报告对网络设备的价值，从而使得网络设备能够合理地进 行网络优化，最终提高用户的服务质量。
在一些可能的设计中，测量配置信息还用于配置第一条件，第一条件用于触发目标小区的测量，第一条件包括第二时间信息和/或第二位置信息，第二时间信息指示启动测量的时间，第二位置信息指示启动测量的位置；对目标小区进行测量，包括：在第一条件满足的情况下，对目标小区进行测量。

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、无线资源控制(radio resource control，RRC)状态：
本申请中，终端设备的RRC状态可以分为RRC连接状态和RRC非连接状态。当终端设备处于RRC连接状态时，终端设备与网络设备之间存在RRC连接，当终端设备处于RRC非连接状态时，终端设备与网络设备之间不存在RRC连接。
示例性的，RRC连接状态可以包括RRC连接态(RRC_CONNECTED)，RRC非连接状态可以包括RRC去激活态(RRC_INACTIVE)和RRC空闲态(RRC_IDLE)中的至少一种。
可以理解的是，本申请并不限定RRC非连接状态仅包括RRC去激活态和RRC空闲态，在未来的协议中可能出现其他RRC非连接状态。
以新空口(new radio，NR)系统为例，在NR中，当终端设备处于RRC连接态时，终端设备与接入网设备以及核心网都已经建立了连接，终端设备可以和网络进行数据传输；当终端设备处于RRC去激活态时，终端设备保留了终端设备在接入网设备和核心网之间的链路，挂起了终端设备和接入网设备之间的链路。此时，终端设备和接入网设备保存有终端设备的上下文，当有数据需要传输时，终端设备可以快速地恢复终端设备和接入网设备之间的链路。当终端设备处于RRC空闲态时，终端设备释放了终端设备与接入网设备的链路，以及终端设备和核心网之间的链路，当有数据需要传输时，需要建立终端设备到接入网设备以及核心网的链路。
示例性的，上述三种状态的转换可以如图1所示。终端设备处于RRC空闲态时，可以通过建立和网络设备间的RRC连接进入RRC连接态；终端设备处于RRC连接态时，网络设备可以释放终端设备的RRC连接，配置终端设备进入RRC去激活态或者RRC空闲态；终端设备处于RRC去激活态时，可以发起恢复RRC连接的请求，网络设备可以配置终端设备进入RRC连接态或者空闲态。
可以理解的是，上述RRC状态仅为一种举例，不应对本申请构成任何限定。本申请 也并不排除在未来的协议中定义其他可能的命名来替代现有命名，但具有相同或相似的特性，或者也有可能出现其他的状态。
2、移动性管理：
移动性管理是无线通信系统中的重要组成部分，指的是为了保证网络与终端之间的通信链路不因终端的移动而中断所涉及的相关内容的统称。可以分为空闲态移动性管理和连接态移动性管理两部分。在空闲态/去激活态下，移动性管理主要指的是小区选择/重选(cell selection/reselection)的过程，在连接态下，移动性管理主要指的是小区切换(handover)。不论是小区选择/重选还是切换，都是基于测量的结果进行的，因此移动性测量是移动性管理的基础。
下面分别对连接态的测量、小区选择、以及小区重选进行说明。
2.1、连接态的测量：
示例性的，如图2所示，地面通信网络中连接态的测量可以包括如下步骤：
S201、网络设备向终端设备发送测量配置。相应的，终端设备接收来自网络设备的测量配置。
其中，测量配置包括一个或多个测量标识，每个测量标识关联一个或多个测量对象的标识(identifier，ID)和上报配置的标识。测量对象即为终端设备要进行测量的目标，通常为一个或者多个小区。上报配置的信元结构可以如下所示：
Figure PCTCN2022081015-appb-000001
triggerQuantity：触发事件的测量量。例如为RSRP或者RSRQ；
reportQuantity：上报的测量量。例如为RSRP或RSRQ，或者，为RSRP和RSRQ；
maxReportCells：一次上报中最多允许的小区数目；
reportInterval：周期上报、或者事件触发的周期上报的每次测量上报间隔；
reportAmount：周期上报、或者事件触发的周期上报的最大测量上报总数。
其中，A1～A5具体如下：
A1：服务小区质量大于某个阈值：
Equation A1-1(Entering condition)；
Equation A1-2(Leaving condition)。
A2：服务小区质量低于某个阈值：
Equation A2-1(Entering condition)；
Equation A2-2(Leaving condition)。
A3：邻区质量高于服务小区质量，且高于某个阈值：
Equation A3-1(Entering condition)；
Equation A3-2(Leaving condition)。
A4：邻区质量高于某个阈值：
Equation A4-1(Entering condition)；
Equation A4-2(Leaving condition)。
A5：邻区质量高于某个阈值、且服务小区质量低于某个阈值：
Equation A5-1(Entering condition 1)；
Equation A5-2(Entering condition 2)；
Equation A5-3(Leaving condition 1)；
Equation A5-4(Leaving condition 2)。
其中，entering condition为进入条件，即信号质量满足该条件时触发上报；leaving condition为离开条件，即信号质量与该条件不符时停止上报。
S202、终端设备根据测量配置进行测量，得到测量结果。
其中，测量结果包括的内容包括测量配置所配置的上报的测量量。
S203、终端设备上报测量结果。
其中，终端设备在触发事件发生时或上报周期到达时上报测量结果。
本申请仅是示例性的对连接态测量的部分内容进行说明，详细说明可参考现有标准的定义，在此不再赘述。
2.2、小区选择：
当终端设备开机或发生无线链路失败等情况下，终端设备将执行小区搜索过程，并尽快选择合适的小区驻留，这个过程称为“小区选择”。
在小区选择过程中，终端设备根据某些条件评估某个小区是否为合适的小区，一旦找到合适的小区，小区选择过程完成。如果某个小区不是合适的小区，终端设备继续进行搜索，直到找到合适的小区并驻留。
根据第三代合作伙伴计划(3rd generation partnership project，3GPP)标准TS 38.304，终端可能驻留的小区称为suitable cell，即合适小区，合适小区具备以下条件：
1)、小区的公共陆地移动网络(public land mobile network，PLMN)是选择的PLMN(selected PLMN)、注册PLMN(registered public land mobile network，RPLMN)、等效PLMN(equivalent public land mobile network，EPLMN)中的一个。
2)、满足S准则，终端设备可以通过读取小区广播的各种参数，计算得到该小区是否满足S准则。
具体的，满足S准则指S rxlev＞0且S qual＞0，即小区的S值大于0的情况下，该小区满足S准则，或者说，该小区是合适小区或适合驻留的小区。S rxlev＞0和S qual＞0满足如下公式：
S rxlev＝Q rxlevmeas-(Q rxlevmin+Q rxlevminoffset)-P compensation-Qoffset temp
S qual＝Q qualmeas-(Q qualmin+Q qualminoffset)-Qoffset temp
其中：
S rxlev是小区选择/重选过程中计算得到的电平值(dB)；
Q rxlevmeas是终端设备测量得到的接收信号强度值，该值为测量到的RSRP(dBm)；
Q rxlevmin是该小区需要的最小接收信号强度值，该值在系统信息块(system information block，SIB)1的q-RxLevMin中指示(dBm)；
P compensation为max(PEMAX–PUMAX，0)(dB)，PEMAX为终端设备在接入该小区时，系统设定的最大允许发送功率；PUMAX是根据终端等级规定的最大输出功率。
Q rxlevminoffset只有在正常驻留在一个访问PLMN(visited public land mobile network，VPLMN)，周期性搜索高优先级的PLMN进行小区选择评估时有效，该参数对Q rxlevmin进行一定的偏置。
其中，其他参数的定义可参考标准中的相关描述，在此不再赘述。
3)、小区未禁止终端设备接入。
4)、小区的PLMN在满足第一条的前提下，其中的至少一个跟踪区域码(tracking area code，TAC)不在被禁的TA里面。
可以理解的，运营商会根据位置将网络覆盖的地区划分成不同的跟踪区(tracking area，TA)，每个PLMN有各自的一套TA规则。
2.3、小区重选：
当RRC空闲态的终端设备驻留在一个小区后，随着终端设备的移动，可能需要更换到另一个优先级更高或信号质量更好的小区驻留，这就是小区重选过程。小区选择是尽快找到一个合适小区的过程，小区重选是选择更适合小区的过程。重选过程中，终端设备会根据RRC释放消息和驻留小区的广播消息中的频点和优先级对邻区进行测量。
可选的，终端设备会在一些事件后删除这些优先级，如RRC状态改变，相关的定时器超时，发生了PLMN选择，再次收到RRC释放消息等。
小区重选后的小区也要符合小区选择过程涉及的合适小区的条件，除此之外，还要满足执行测量准则和重选准则：
执行测量准则，用于终端设备决定是否开始对小区进行测量，具体包括：
对于优先级高于服务小区的频率或系统，终端设备始终对其进行测量；
如果服务小区的Srxlev<＝Sintrasearch，终端设备启动对同频小区的测量；
如果服务小区的Srxlev<＝Snonintrasearch或Snonintrasearch未配置，终端设备启动对同优先级频率或低优先级频率及系统的测量。
重选准则，用于终端设备在测量后决定是否执行小区重选到新的小区，具体包括：
高优先级频率或系统的重选标准：目标频率小区的Srxlev>Threshx_high且持续TreselectionRAT时间；
低优先级频率或系统的重选标准：服务小区的Srxlev<Threshserving_low，且目标频率小区的Srxlev>Threshx_low且持续TreselectionRAT时间；
同优先级频率或系统的重选标准：基于同频小区重选的Ranking标准。
上述执行测量准则和重选准则的涉及到的参数可参考标准中的相关说明，在此不再赘述。
3、条件切换(conditional handover，CHO)：
CHO机制用于提升切换成功率。如图3所示，在CHO机制中，源网络设备在源链路质量较好时向终端设备发送CHO配置信息，该CHO配置信息中可以包括切换触发条件、一个或多个候选小区的信息，例如，候选小区的CGI，或者，候选小区的物理小区标识(physical cell identifier，PCI)以及候选小区对应的频率信息。
示例性的，源网络设备可以通过现有的RRC消息发送CHO配置信息，或者，源网 络设备可以通过新定义的RRC消息发送CHO配置信息，例如，该RRC消息可以是条件RRC重配置消息(如CondRRCReconfiguration)，或者其他命名/表达形式，对此不作限定。
终端设备在接收到该CHO配置信息后，根据该配置信息判断候选小区是否满足切换触发条件，将满足切换触发条件的候选小区作为目标小区；然后，终端设备与确定出的目标小区进行随机接入过程，当随机接入成功完成，终端设备向目标小区所属的网络设备(即目标网络设备，图3中以候选网络设备1为目标网络设备为例进行说明)发送RRC消息(如RRC重配置完成消息)，通知目标网络设备条件切换完成。
此外，在源网络设备向终端设备发送CHO配置信息之前，还可以向终端设备发送RRC重配置消息，用于测量配置，终端设备在根据测量配置进行测量后向源网络设备发送测量报告。源网络设备根据测量报告向一个或多个候选网络设备发送CHO请求(CHO request)(图3以候选网络设备1和候选网络设备2为例)，请求将候选网络设备的小区作为CHO的候选小区，若候选网络设备同意，向源网络设备发送CHO请求确认(CHO request ACK)。源网络设备收到CHO请求确认后，可以确定CHO配置信息，随后发给终端设备。
4、非地面网络(non-terrestrial network，NTN)通信：
如图4所示，按照承载基站或基站功能的平台距离地面的高度，NTN可以包括低空平台(low altitude platform，LAP)子网(LAP subnetwork)、高空平台(high altitude platform，HAP)子网(HAP subnetwork)、以及卫星通信子网(SATCOM subnetwork)。
其中，LAP subnetwork中，基站或基站功能部署于距离地面0.1km至1km的低空飞行平台上为终端设备提供覆盖，例如无人机；HAP subnetwork中，基站或基站功能部署于距离地面1km至50km的高空飞行平台上为终端设备提供覆盖，例如飞机；SATCOM subnetwork中，基站或基站功能部署于距离地面50km以上的卫星上为终端设备提供覆盖。卫星通信具有全球覆盖、远距离传输、组网灵活、部署方便和不受地理位置限制等显著优点，已经被广泛应用于海上通信、定位导航、抗险救灾、科学实验、视频广播、对地观测等多个领域。
进一步的，按照卫星高度，即卫星轨位高度，如图5所示，可以将卫星分为高椭圆轨道(highly elliptical orbiting，HEO)卫星、高轨(geostationary earth orbit，GEO)卫星、中轨(medium earth orbit，MEO)卫星和低轨(low-earth orbit，LEO)卫星。其中，GEO卫星又称静止卫星，其运动速度与地球自转速度相同，因此GEO卫星相对地面保持静止状态，对应的，GEO卫星的小区也是静止的。GEO卫星小区的覆盖较大，一般情况下小区的直径为500km。LEO卫星相对地面移动较快，大约7Km每秒，因此LEO卫星提供的服务覆盖区域也随之移动。通常来说，卫星的轨道越高其覆盖面积越大，但是其通信时延也越长。
其中，低轨卫星通信系统距离地面近、通信时延短、数据传输率高，移动终端的重量体积与个人移动设备相差无几，更适合大众市场普及，成为当前产业发展的热点。从1990年至今，数个低轨和中轨卫星通信网络已经正式提供商业服务，其中比较著名的包括低轨的铱星网络和中轨的O3b网络。

另外，为了便于清楚描述本申请实施例的技术方案，在本申请的实施例中，采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样也并不限定一定不同。同时，在本申请实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念，便于理解。
可以理解，说明书通篇中提到的“实施例”意味着与实施例有关的特定特征、结构或特性包括在本申请的至少一个实施例中。因此，在整个说明书各个实施例未必一定指相同的实施例。此外，这些特定的特征、结构或特性可以任意适合的方式结合在一个或多个实施例中。可以理解，在本申请的各种实施例中，各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
可以理解，在本申请中，“当…时”、“若”以及“如果”均指在某种客观情况下会做出相应的处理，并非是限定时间，且也不要求实现时一定要有判断的动作，也不意味着存在其它限定。
本申请中的“同时”可以理解为在相同的时间点，也可以理解为在一段时间段内，还可以理解为在同一个周期内。
本申请实施例的技术方案可用于各种通信系统，该通信系统可以为第三代合作伙伴计划(third generation partnership project，3GPP)通信系统，例如，长期演进(long term evolution，LTE)系统，又可以为第五代(fifth generation，5G)移动通信系统、新空口(new radio，NR)系统、新空口车联网(vehicle to everything，NR V2X)系统，还可以应用于LTE和5G混合组网的系统中，或者设备到设备(device-to-device，D2D)通信系统、机器到机器(machine to machine，M2M)通信系统、物联网(Internet of Things，IoT)，以及其他下一代通信系统，也可以为非3GPP通信系统，不予限制。

参见图6，为本申请实施例提供的一种通信系统。该通信系统包括至少一个网络设备20，以及与该网络设备20连接的一个或多个终端30。可选的，不同的终端30之间可 以相互通信。
以图6所示的网络设备20与任一终端30进行交互为例，本申请实施例中，网络设备向终端设备发送测量配置信息，该测量配置信息用于配置目标小区，该目标小区包括服务小区和邻区。终端设备对目标小区进行测量，得到目标小区的测量报告后，向网络设备发送该目标小区的测量报告。其中，该测量报告包括第一时间信息和/或第一位置信息，该第一时间信息包括以下一项或多项：服务小区的覆盖剩余时间、邻区的覆盖剩余时间、或邻区即将到来的时间；第一位置信息包括：终端所处的位置与服务小区的中心位置之间的距离，和/或，终端所处的位置与邻区的中心位置之间的距离；或者，第一位置信息包括：终端所处的位置与服务小区的边缘位置之间的距离，和/或，终端所处的位置与邻区的边缘位置之间的距离。本申请提供的具体方案将在后续实施例中详细说明，在此不予赘述。
本申请中，基于时间和/或位置进行测量，向网络设备上报与小区覆盖相关的第一时间信息和/或第一位置信息，在网络设备或终端设备高速移动的远距离通信场景下，如NTN中，相比于单纯基于信号质量的测量以及上报信号质量相关的信息，可以提高测量的合理性，提升测量报告对网络设备的价值，从而使得网络设备能够合理地进行网络优化，最终提高用户的服务质量。
本申请涉及的终端30，可以是用于实现无线通信功能的设备，例如终端设备或者可用于终端中的芯片等。其中，终端可以是IoT、5G网络、或者未来演进的PLMN中的用户设备(user equipment，UE)、接入终端、终端单元、终端站、移动站、移动台、远方站、远程终端、移动设备、无线通信设备、终端代理或终端装置等。接入终端可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备或可穿戴设备，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、远程医疗(remote medical)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)中的无线终端等。终端可以是移动的，也可以是固定的。
本申请涉及的网络设备20，是无线接入网(radio access network，RAN)中的一种将终端30接入到无线网络的设备，RAN可以与核心网相连(例如可以是LTE的核心网，也可以是5G的核心网等)。
网络设备20可以是LTE中的演进型基站(evolutional Node B，eNB或eNodeB)；或者5G网络或者未来演进的公共陆地移动网络(public land mobile network，PLMN)中的基站，宽带网络业务网关(broadband network gateway，BNG)，汇聚交换机或非3GPP接入设备；或者本申请实施例中的网络设备20还可以是云无线接入网络(cloud radio access network，CRAN)中的无线控制器；或者传输接收节点(transmission and reception point，TRP)，或者包括TRP的设备等，本申请实施例对此不作具体限定。可选的，本申请实施例中的基站可以包括各种形式的基站，例如：宏基站，微基站(也称为小站)，中继站，接入点等，本申请实施例对此不作具体限定。
或者，网络设备20也可以是指RAN中的集中单元(central unit，CU)或者分布式单元(distributed unit，DU)，或者，如图7所示，网络设备也可以是CU和DU组成的。 多个DU可以共用一个CU。一个DU也可以连接多个CU(图7中未示出)。CU和DU之间可以通过接口相连，例如可以是F1接口。
CU和DU可以理解为是对网络设备从逻辑功能角度的划分。其中，CU和DU在物理上可以是分离的，也可以部署在一起，本申请实施例对此不做具体限定。CU和DU可以根据无线网络的协议层划分。例如，无线资源控制(radio resource control，RRC)协议层、业务数据适配协议栈(service data adaptation protocol，SDAP)协议层以及分组数据汇聚层协议(packet data convergence protocol，PDCP)协议层的功能设置在CU中，而无线链路控制(radio link control，RLC)协议层，媒体接入控制(media access control，MAC)协议层，物理(physical，PHY)协议层等的功能设置在DU中。
可以理解，对CU和DU处理功能按照这种协议层的划分仅仅是一种举例，也可以按照其他的方式进行划分。
例如，可以将CU或者DU划分为具有更多协议层的功能。例如，CU或DU还可以划分为具有协议层的部分处理功能。在一种设计中，将RLC层的部分功能和RLC层以上的协议层的功能设置在CU，将RLC层的剩余功能和RLC层以下的协议层的功能设置在DU。在另一种设计中，还可以按照业务类型或者其他系统需求对CU或者DU的功能进行划分。例如按时延划分，将处理时间需要满足时延要求的功能设置在DU，不需要满足该时延要求的功能设置在CU。在另一种设计中，CU也可以具有核心网的一个或多个功能。一个或者多个CU可以集中设置，也分离设置。例如CU可以设置在网络侧方便集中管理。DU可以具有多个射频功能，也可以将射频功能拉远设置。
进一步的，CU的功能可以由一个实体来实现也可以由不同的实体实现，例如，CU可以由CU控制面(CU control plane，CU-CP)和CU用户面(CU user plane，CU-UP)组成，CU-CP和CU-UP可以理解为是对CU从逻辑功能的角度进行划分。其中，CU-CP和CU-UP可以根据无线网络的协议层划分，例如，RRC协议层和信令无线承载(signal radio bearer，SRB)对应的PDCP协议层的功能设置在CU-CP中，数据无线承载(data radio bearer，DRB)对应的PDCP协议层的功能设置在CU-UP中。此外，SDAP协议层的功能也可能设置在CU-UP中。
在一些实施例中，本申请实施例中的网络设备可以搭载或部署于飞行平台，例如低空飞行平台、高空飞行平台或者卫星。当网络设备搭载在飞行平台上时，网络设备与飞行平台同步移动。
作为一种示例，参照图8a，网络设备可以搭载在飞行平台上作为层1中继(L1relay)，重新生成物理层信号并转发给地面站或终端，地面站通过核心网与数据网络通信。
作为另一种示例，参照图8b，网络设备可以搭载在飞行平台上实现地面站的功能，直接与核心网通信，进一步的，通过核心网与数据网络通信。

作为又一种示例，参照图8d，网络设备可以是搭载在飞行平台上DU，与部署于地面的CU通过FI接口通信。部署于地面的CU与核心网通信，进一步的，通过核心网与数据网络通信。
在一些实施例中，网络设备20与终端30也可以称之为通信装置，其可以是一个通 用设备或者是一个专用设备，本申请实施例对此不作具体限定。

S1001、网络设备向终端发送测量配置信息。相应的，终端接收来自网络设备的测量配置信息。
可以理解的是，在该步骤S1001之前，网络设备需要生成该测量配置信息。

在一些实施例中，小区的覆盖剩余时间可以理解为：小区能够为终端提供服务的剩余时间。邻区即将到来的时间可以理解为：当前时刻邻区还未覆盖终端，但是在一段时间后，邻区可能会覆盖终端，或者说，可能为终端提供服务，该段时间即可理解为邻区即将到来的时间，或者理解为终端等待该邻区的时间，从而“邻区即将到来的时间”也可以称为“终端等待邻区的时间”，或“终端等待邻区到来的时间”，不予限制。
示例性的，在终端与网络设备之间的距离不断发生变化的通信场景下，或者说，在网络设备或终端快速移动的场景下，例如卫星通信场景下，由于网络设备处于高速移动状态，其小区的覆盖范围会发生变化，假设时刻1网络设备的小区1的覆盖范围在范围1，随着网络设备的移动，时刻2其覆盖范围可能为范围2，若终端在范围1内静止，此时就会存在小区1的覆盖剩余时间。
在一些实施例中，上述时间可以是相对时间，例如，覆盖剩余时间可以为覆盖剩余时长，即还能覆盖多久，即将到来的时间可以为还有多久到达；或者，上述时间可以是绝对时间(如国际通用时间(coordinated universal time，UTC))，例如，覆盖剩余时间可以为提供覆盖的最后时间，即能够覆盖到的最后时刻，即将到来的时间可以为到来的时刻；或者，上述时间还可以用系统帧号、子帧号、时隙号等表示。
在一些实施例中，在服务小区或邻区包括多个波束的情况下，终端可以得到每个波束的覆盖剩余时间或每个波束即将到来的时间，最终，该小区的覆盖剩余时间可以是多个波束的覆盖剩余时间的平均值或最小值或最大值或中间值等，类似的，该小区即将到来的时间可以是多个波束即将到来的时间的平均值或最小值或最大值或中间值等。

在一些实施例中，在服务小区或邻区包括多个波束的情况下，终端可以得到终端所处的位置与每个波束的覆盖中心位置之间的距离，和/或，得到终端所处的位置与每个波束的覆盖边缘位置之间的距离，最终，终端所处的位置与小区的中心位置之间的距离可以是与每个波束的覆盖中心位置之间的距离的平均值或最小值或最大值或中间值等，类似的，终端所处的位置与小区的边缘位置之间的距离可以是与每个波束的覆盖边缘位置之间的距离的平均值或最小值或最大值或中间值等。
需要说明的是，上述距离可以是直线距离，也可以是其他类型的距离，本申请对此不作具体限定。
在一些实施例中，除第一时间信息和/或第一位置信息之外，该测量报告还可以包括第一信号质量信息，该第一信号质量信息包括服务小区的信号质量，和/或，邻区的信号质量。也就是说，本申请可以将基于信号质量的测量，以及基于时间和/或位置的测量进行结合，从而提高测量的全面性。
S1003、终端向网络设备发送目标小区的测量报告。相应的，网络设备接收来自终端的测量报告。
在一些实施例中，网络设备收到测量报告后，可以根据测量报告进行移动性策略，例如在服务小区对终端的覆盖时间小于某个阈值时，做出切换决策，将该终端切换到邻区。或者，网络可以根据测量报告进行网络优化，例如覆盖优化、容量优化等；或者，可以根据测量报告进行配置优化，本申请对此不作具体限定。
基于该方案，本申请基于时间和/或位置进行测量，向网络设备上报与小区覆盖相关的第一时间信息和/或第一位置信息，在网络设备或终端设备高速移动的远距离通信场景下，如NTN中，相比于单纯基于信号质量的测量以及上报信号质量相关的信息，可以提高测量的合理性，提升测量报告对网络设备的价值，从而使得网络设备能够合理地进行网络优化，最终提高用户的服务质量。
在一些实施例中，终端还向网络设备发送第二指示信息，该第二指示信息指示目标小区包括的邻区是否覆盖到了终端。

在网络设备高速移动的场景，例如卫星通信中，通信往返时延长，该测量配置信息可能是提前下发的，即网络设备可能下发当前还未覆盖但是一段时间后会覆盖终端的邻区的测量配置，在该情况下，若终端收到测量配置立即开始测量，可能会测量不到。基于该方案，网络设备在测量配置中配置触发测量的第一条件，使得终端能够在满足第一条件的情况下启动目标小区的测量，从而节省了终端的功耗。
