具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
当前，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、复杂性，为此第三代合作伙伴项目(Third Generation Partnership Project，3GPP)国际标准组织开始研发第五代通信(5th-Generation，5G)。5G的主要应用场景为：增强移动超宽带(Enhanced Mobile Broadband，eMBB)、低时延高可靠通信(Ultra-Reliable & Low-Latency Communication，URLLC)、大规模机器类通信(massive Machine Type of Communication，mMTC)。
新空口(New Radio，NR)也可以独立部署，5G网络环境中为了降低空口信令和快速恢复无线连接，快速恢复数据业务的目的，定义一个新的无线资源控制(Radio Resource Control，RRC)状态，即RRC不 活跃(RRC_INACTIVE)状态。这种状态有别于RRC空闲(RRC_IDLE)状态和RRC活跃(RRC_ACTIVE)状态。
RRC_IDLE：移动性为基于终端的小区选择重选，寻呼由终端发起，寻呼区域由终端配置。网络设备侧不存在终端接入层(Access Stratum，AS)上下文，不存在RRC连接。
RRC_CONNECTED：存在RRC连接，网络设备和终端存在终端接入层上下文。网络设备侧确定终端的位置是具体小区级别的进行的，移动性是网络设备侧控制的移动性。终端和网络设备之间可以传输单播数据。
RRC_INACTIVE：移动性为基于终端的小区选择重选，存在核心网(Core Network，CN)与NR之间的连接，可简写为CN-NR之间的连接，终端接入层上下文存在某个网络设备上，寻呼由无线接入网(Radio Access Network，RAN)触发，基于RAN的寻呼区域由RAN管理，网络设备侧确定终端的位置是基于RAN的寻呼区域级别的进行的。
在介绍本申请技术方案之前，下面先对本申请相关知识进行说明：
窄带物联网(NarrowBand Internet of Things，NB-IoT)中处于非连接态的终端的无线资源管理(Radio Resource Management，RRM)测量：
处于非连接态的终端(User Equipment，UE)，需要基于网络的配置对服务小区以及其他邻小区进行RRM测量以支持移动性操作，例如小区重选等。
示意性的，非连接态的UE针对服务小区的测量是持续进行的。在NB-IoT中，可引入了针对静止终端的邻小区测量放松机制，以进一步满足终端省电的需求。针对邻小区测量放松引入的测量放松准则，网络设备会配置窄带参考信号接收功率(Narrowband Reference Signal Received Quality，NRSRP)变化的评估时长和参考信号接收功率(Reference Signal Received Power，RSRP)变化值门限。其中，评估时长可用TSearchDeltaP指示，RSRP变化值门限可用SSearchDeltaP指示。
当一段时间TSearchDeltaP内UE在服务小区上的RSRP变化量小于SSearchDeltaP时，则认为该UE满足测量放松准则。
示意性的，在一段时间TSearchDeltaP内，满足：
(SrxlevRef–Srxlev)<SSearchDeltaP   <公式1>。
其中，Srxlev是服务小区的当前Srxlev测量值，SrxlevRef是服务小区的参考Srxlev值。
当UE选择或重选到一个新的小区，或者(Srxlev-SrxlevRef)>0，或者，UE没有在持续TSearchDeltaP时间内满足<公式1>，UE将SrxlevRef设为服务小区的当前Srxlev测量值；随后，UE在完成小区选择/重选之后，需要在至少一段时间TSearchDeltaP内执行正常的RRM测量。
可选的，当UE满足测量放松准则时，UE针对邻小区的测量间隔可以增大到24小时。
NR中处于连接态的UE的RRM测量：
示意性的，NB-IoT UE不支持连接态的RRM测量。当连接态的NB-IoT在服务小区上的信道质量变差后，通过无线链路失败(Radio Link Failure，RLF)和RRC重建过程来进行移动性管理。
其中，由于UE触发RLF之后，需要先通过搜索、测量来选择一个合适的小区，然后在该小区上发起RRC连接重建。为节省UE触发RLF之后选择重建小区的时间，可针对NB-IoT UE引入了连接态UE的邻区测量机制。
针对连接态UE的邻区测量，网络会通过系统消息配置S测量(s-measure)准则，同时网络还可以为终端配置UE移动状态评估准则。随后UE基于s-measure准则和UE移动状态评估准则，确定是否需要执行邻小区测量。方法如下：
当UE进入到RRC连接态之后，如果网络配置了UE移动状态评估准则，则：
-将NRSRP参考值(NRSRP Ref)设置为最近一次测得的用于小区选择/重选的服务小区上的NRSRP；
-如果UE在进入RRC连接态之前没有满足邻小区测量放松准则，则UE启动对应的定时器，定时器可用T3AB指示。其中，A、B可以是相同的整数，也可以是不同的整数，A、B的取值范围为0-9。应当理解的是，T3AB还可用其他方式进行表述，如T3XX，其中的“XX”用于代替相同或不同的整数。
对于处于连接态的UE，假设UE在被测载波上的测量结果为NRSRP，如果网络配置了UE移动状态评估准则，则：
-如果(NRSRP Ref-(NRSRP-PowerOffsetNonAnchor))>s-MeasureDeltaP，则UE设置NRSRP Ref＝NRSRP-PowerOffsetNonAnchor，同时UE启动或重启T3AB。
如果网络没有配置UE移动状态评估准则，或者T3AB正在运行：
-如果(NRSRP-PowerOffsetNonAnchor)<s-MeasureIntra，则UE执行对同频邻小区的测量。
-如果(NRSRP-PowerOffsetNonAnchor)<s-MeasureInter，则UE执行对异频邻小区的测量。
Non Terrestrial Network(NTN，非地面通信网络)相关背景：
目前3GPP正在研究NTN技术，NTN技术一般采用卫星通信的方式向地面用户提供通信服务。相比地面蜂窝网通信，卫星通信具有很多独特的优点。首先，卫星通信不受用户地域的限制，例如一般的陆地通信不能覆盖海洋、高山、沙漠等无法搭设通信设备或由于人口稀少而不做通信覆盖的区域，而对于卫星通信来说，一颗卫星即可以覆盖较大的地面，加之卫星可围绕地球做轨道运动，因此理论上地球上每一个角落都可被卫星通信覆盖。其次，卫星通信有较大的社会价值。卫星通信在边远山区、贫穷落后的国家或地区均可以较低的成本覆盖到，从而使这些地区的人们享受到先进的语音通信和移动互联网技术，有利于缩小与发达地区的数字鸿沟，促进地区发展。再次，卫星通信距离远，且通信距离增大通讯的成本没有明显增加；最后，卫星通信的稳定性高，不受自然灾害的限制。
通信卫星按照轨道高度的不同分为低地球轨道(Low-Earth Orbit，LEO)卫星、中地球轨道(Medium-Earth Orbit，MEO)卫星、地球同步轨道(Geostationary Earth Orbit，GEO)卫星、高椭圆轨道(High Elliptical Orbit，HEO)卫星等等。目前阶段主要研究的是LEO和GEO。
1.LEO：低轨道卫星高度范围为500km～1500km，相应轨道周期约为1.5小时～2小时。用户间单跳通信的信号传播延迟一般小于20ms。最大卫星可视时间20分钟。信号传播距离短，链路损耗少，对用户终端的发射功率要求不高。
2.GEO：地球同步轨道卫星，轨道高度为35786km，围绕地球旋转周期为24小时。用户间单跳通信的信号传播延迟一般为250ms。
为了保证卫星的覆盖以及提升整个卫星通信系统的系统容量，卫星采用多波束覆盖地面，一颗卫星可以形成几十甚至数百个波束来覆盖地面；一个卫星波束可以覆盖直径几十至上百公里的地面区域。
目前3GPP考虑的卫星有两种，分别是：透明转发(transparent payload)的卫星，如图1所示；再生转发(regenerative payload)的卫星，如图2所示。
其中，馈线连接(feeder link)指的是卫星14和NTN网关16(NTN gateway)之间的无线链路，NTN网关通常位于地面。
示意性的，NTN网络由以下网元组成：
·1个或者多个网关：用于连接卫星和地面公共网络。
·馈线链路：用于网关和卫星之间通信的链路。
·服务链路：用于终端和卫星之间通信的链路。
·卫星：从其提供的功能上可以分为透传载荷和再生载荷这两种。
·透传载荷：只提供无线频率滤波，频率转换和放大的功能。只提供信号的透明转发，不会改变其转发的波形信号。
·再生载荷：除了提供无线频率滤波，频率转换和放大的功能，还可以提供解调/解码，路由/转换，编码/调制的功能。其具有基站的部分或者全部功能。
·星间链路(Inter-Satellite Links，ISL)：存在于再生载荷场景下。
图3示出了不同场景下的远近效应的示意图。
示意性的如图3的(a)所示，在地面网络中，UE处于小区中心时的参考信号接收功率(N)RSRP要明显高于其处于小区边缘时的(N)RSRP。由于存在明显的“远近效应”，因此可以基于(N)RSRP测量判断是否满足邻区测量启动条件，即在网络配置了s-measure准则的情况下，UE可以通过对服务小区的(N)RSRP测量来判断自己是否信道状态不够好；在网络配置了UE移动性评估准则的情况下，UE可以基于自己在服务小区上的(N)RSRP变化量判断自己是否不满足低移动性或静止状态。
示意性的如图3的(b)所示，在NTN系统中，对于处于小区中心的UE和处于小区边缘的UE，他们对应的RSRP差异并不明显，如果使用目前的基于RSRP测量来判断UE是否满足s-meausre准则或/和UE移动性评估准则，一方面网络很难设置合适的RSRP门限，另一方面，由于RSRP测量存在误差，很可能导致UE执行了不合适的测量操作。例如，在网络配置了s-measure准则的情况下，对于小区中心的用户，由于测量的RSRP偏低导致启动了邻小区测量，增加了不必要的终端功耗；对于小区边缘的用户，由于测量的RSRP偏高导致没有启动针对邻小区的测量，当UE触发了RLF之后增加了RRC重建的时间，从而影响了终端的体验。
基于上述内容，本申请实施例提供了一种NTN中的邻小区测量方法，以满足终端的移动性管理的需求。图4示出了本申请一个示例性实施例提供的NTN中的邻小区测量方法的流程图，该方法由终端执行， 该方法包括如下步骤：
步骤102：基于终端到服务小区参考点之间的距离和/或距离变化量是否满足基于终端位置的评估准则，启动对邻小区的测量。
其中，终端到服务小区参考点之间的距离和/或距离变化量可根据距离参考值确定。距离参考值可用Dref表示，可选的，距离参考值可由网络设备可向终端配置、或者由终端自主确定。
比如，终端将距离参考值确定为实时距离或最近一次测量距离，实时距离是终端的实时位置与服务小区参考点之间的距离，最近一次测量距离是终端最近一次获取到的有效终端位置与服务小区参考点之间的距离。其中，终端的实时位置，是指终端在确定终端到服务小区参考点之间的距离和/或距离变化量的时间节点下的位置；终端最近一次获取到的有效终端位置，是指终端在确定终端到服务小区参考点之间的距离和/或距离变化量的时间节点之前的最近一次获取到的终端位置。
可选的，在NB-IoT中，服务小区参考点是锚点(anchor)载波对应的参考点。
基于终端位置的评估准则可由网络设备向终端配置。在配置基于终端位置的评估准则时，网络设备可为终端配置评估准则对应的评估时长和/或门限，以便于终端进行判断。
示意性的，基于终端位置的评估准则可以是基于终端位置的移动性状态评估准则，或者是基于终端位置的S测量(S-measure)准则。其中，移动性状态评估准则用于评估终端的移动性状态，S测量准则用于判断终端是否处于小区边缘。
以基于终端位置的评估准则是第一准则为例，步骤102可实现为：
在满足邻区测量启动条件的情况下，启动对邻小区的测量；
其中，邻区测量启动条件至少包括：终端到服务小区参考点之间的距离变化量不满足第一准则，第一准则是基于终端位置的移动性状态评估准则。
可选的，在第一准则对应于第一评估时长和第一门限的情况下，在第一评估时长内，在终端到服务小区参考点之间的距离变化量小于或等于第一门限的情况下，确定距离变化量满足第一准则，距离变化量是基于距离参考值确定的。
其中，第一评估时长可用t-MeasureDeltaD表示；第一门限是与第一准则对应的距离变化量门限，可用s-MeasureDeltaD表示；距离变化量用于指示终端到服务小区参考点之间的距离相对于距离参考值的变化量，包括距离增大或减小两种情况。
可选的，距离变化量根据距离参考值确定。其中，距离参考值可由网络设备为终端配置，也可由终端自主确定，距离参考值可用Dref表示。
可选的，在第一准则对应有用于评估终端移动性状态的定时器的情况下，第一准则对应的第一定时器的时长为第一评估时长。其中，第一准则对应的第一定时器可用T3XY表示。其中，X、Y可以是相同的整数，也可以是不同的整数，X、Y的取值范围为0-9。应当理解的是，T3XY还可用其他方式进行表述，如T3YY，其中的“YY”用于代替相同或不同的整数。
根据前述内容，距离变化量满足第一准则的条件为：在第一评估时长内，且终端到服务小区参考点之间的距离变化量小于或等于第一门限。其中，在第一评估时长内可实现为第一准则对应的第一定时器正在运行。应当理解的是，除上述条件外，其他任意一种情况均属于距离变化量不满足第一准则的情况。比如，第一准则对应的第一定时器正在运行，则确定距离变化量不满足第一准则；又如，第一准则对应的第一定时器正在运行，且终端到服务小区参考点之间的距离变化量大于第一门限，则确定距离变化量不满足第一准则。
可选的，邻区测量启动条件还包括如下条件中的至少一种：第一准则对应的第一定时器正在运行，且终端满足S测量准则对应的测量启动条件；第二准则对应的第二定时器正在运行，且终端满足S测量准则对应的测量启动条件；第一准则对应的第一定时器正在运行，且第二准则对应的第二定时器正在运行，且终端满足S测量准则对应的测量启动条件。
其中，第二准则是基于信道质量的移动性状态评估准则，第二准则对应的第二定时器可用T3AB表示。比如，第二准则是基于(N)RSRP的移动性状态评估准则。
可选的，S测量准则对应的测量启动条件为：终端到服务小区参考点之间的距离不满足第三准则；终端不满足第四准则；终端到服务小区参考点之间的距离不满足第三准则，且终端不满足第四准则。其中，第三准则是基于终端位置的S测量准则，第四准则是基于信道质量的S测量准则。第三准则和第四准则的相关描述将在下文展开，此处不做具体描述。
可选的，第一准则对应的第一定时器和第二准则对应的第二定时器可以是不同的定时器，也可以是相同的定时器。在第一准则对应的第一定时器和第二准则对应的第二定时器是不同的定时器的情况下，第一准则使用T3XY定时器，第二准则使用T3AB定时器。在第一准则对应的第一定时器和第二准则对应的第二定时器是相同的定时器的情况下，可使得第一准则和第二准则共同使用T3AB定时器。
其中，A、B可以是相同的整数，也可以是不同的整数，A、B的取值范围为0-9；X、Y可以是相同的整数，也可以是不同的整数，X、Y的取值范围为0-9。应当理解的是，T3XY还可用其他方式进行表述，如T3YY，其中的“YY”用于代替相同或不同的整数；T3AB还可用其他方式进行表述，如T3XX，其中的“XX”用于代替相同或不同的整数。
以基于终端位置的评估准则是第三准则为例，步骤102可实现为：

假设在第一评估时长内，在终端移动至内实线圆和虚线圆之间的区域时，则存在距离变化量，且距离变化量的取值为D-Dref。此时，终端到服务小区参考点之间的距离变化量小于或等于第一门限，则可确定距离变化量满足第一准则。
随后，终端继续向远离服务小区参考点的方向移动，在终端移动至虚线圆和外实线圆之间的区域时，将存在(D-Dref)>s-MeasureDeltaD，也将不再满足距离变化量满足第一准则的条件。此时，可确定距离变化量不满足第一准则，终端启动对邻小区的测量。

其中，实时距离是终端的实时位置与服务小区参考点之间的距离，最近一次测量距离是终端最近一次获取到的有效终端位置与服务小区参考点之间的距离。
根据前述内容，若不存在实时距离且不存在最近一次测量距离，终端将无法确定终端到服务小区参考点之间的距离变化量，使得终端无法判断是否满足第一准则。在该情况下，终端可回退使用第二准则进行判断。比如，在该情况下，终端回退使用基于RSRP的移动性状态评估准则判断是否需要启动对邻小区的测量。
