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。
本申请实施例描述的网络架构以及业务场景是为了更加清楚地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，本领域普通技术人员可知，随着网络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。
目前，相关标准组织正在研究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。相比于地面的蜂窝通信网络，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，由于一颗卫星即可以覆盖较大的地面，加之卫星可以围绕地球做轨道运动，因此理论上地球上每一个角落都可以被卫星通信覆盖。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都可以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，促进这些地区的发展。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LEO(Low-Earth Orbit，低地球轨道)卫星、MEO(Medium-Earth Orbit，中地球轨道)卫星、GEO(Geostationary Earth Orbit，地球同步轨道)卫星、HEO(High Elliptical Orbit，高椭圆轨道)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，对用户终端设备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。
请参考图1，其示出了一种卫星网络架构的示意图，该卫星网络架构中的通信卫星是透明转发(transparent payload)的卫星。如图1所示，该卫星网络架构包括：终端设备10、卫星20、NTN网关30、接入网设备40和核心网设备50。
终端设备10和接入网设备40之间可通过空口(如Uu接口)进行通信。在图1所示架构中，接入网设备40可以部署在地面，终端设备10和接入网设备40之间的上下行通信，可以通过卫星20和NTN网关30(通常位于地面)进行中转传输。以上行传输为例，终端设备10将上行信号发送给卫星20，卫星20将上述上行信号转发给NTN网关30，再由NTN网关30将上述上行信号转发给接入网设备40，后续由接入网设备40将上述上行信号发送给核心网设备50。以下行传输为例，来自核心网设备50的下行信号发送给接入网设备40，接入网 设备40将下行信号发送给NTN网关30，NTN网关30将上述下行信号转发给卫星20，再由卫星20将上述下行信号转发给终端设备10。
请参考图2，其示出了另一种卫星网络架构的示意图，该卫星网络架构中的通信卫星是再生转发(regenerative payload)的卫星。如图2所示，该卫星网络架构包括：终端设备10、卫星20、NTN网关30和核心网设备50。
在图2所示架构中，接入网设备40的功能集成在卫星20上，也即卫星20具备接入网设备40的功能。终端设备10和卫星20之间可通过空口(如Uu接口)进行通信。卫星20和NTN网关30(通常位于地面)之间可通过SRI(Satellite Radio Interface，卫星无线接口)进行通信。
在图2所示架构中，以上行传输为例，终端设备10将上行信号发送给卫星20，卫星20将上述上行信号转发给NTN网关30，再由NTN网关30将上述上行信号发送给核心网设备50。以下行传输为例，来自核心网设备50的下行信号发送给NTN网关30，NTN网关30将上述下行信号转发给卫星20，再由卫星20将上述下行信号转发给终端设备10。
在上述图1和图2所示的网络架构中，接入网设备40是用于为终端设备10提供无线通信服务的设备。接入网设备40与终端设备10之间可以建立连接，从而通过该连接进行通信，包括信令和数据的交互。接入网设备40的数量可以有多个，两个邻近的接入网设备40之间也可以通过有线或者无线的方式进行通信。终端设备10可以在不同的接入网设备40之间进行切换，也即与不同的接入网设备40建立连接。
以蜂窝通信网络为例，蜂窝通信网络中的接入网设备40可以是基站。基站是一种部署在接入网中用以为终端设备10提供无线通信功能的装置。基站可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，例如在5G NR系统中，称为gNodeB或者gNB。随着通信技术的演进，“基站”这一名称可能会变化。为方便描述，本申请实施例中，上述为终端设备10提供无线通信功能的装置统称为基站或接入网设备。
另外，本申请实施例中涉及的终端设备10，可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备，以及各种形式的用户设备(User Equipment，UE)，移动台(Mobile Station，MS)，终端设备(terminal device)等等。为方便描述，本申请实施例中，上面提到的设备统称为终端设备。在本申请实施例中，有些地方使用“UE”代表“终端设备”。在本申请实施例中，“网络设备”可以是接入网设备(如基站)或者卫星。
另外，以5G NTN网络为例，NTN网络中可以包括多颗卫星20。一颗卫星20可以覆盖一定范围的地面区域，为该地面区域上的终端设备10提供无线通信服务。另外，卫星20可以围绕地球做轨道运动，通过布设多个卫星20，可以实现对地球表面的不同区域的通信覆盖。
另外，在本申请实施例中，名词“网络”和“系统”通常混用，但本领域技术人员可以理解其含义。本申请实施例描述的技术方案可以适用于LTE(Long Term Evolution，长期演进)系统，也可以适用于5G NR系统，也可以适用于5G NR系统后续的演进系统或者其他通信系统，本申请对此不作限定。
在介绍本申请技术方案之前，先对本申请涉及的一些背景技术知识进行介绍说明。以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。
1.NR系统中的RRC(Radio Resource Control，无线资源控制)状态
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3GPP(3rd Generation Partner Project，第三代合作伙伴计划)国际标准组织开始研发5G。5G的主要应用场景为：eMBB(Enhanced Mobile Broadband，增强移动超宽带)、URLLC (Ultra-reliable and Low Latency Communications，低时延高可靠通信)、mMTC(Massive Machine Type of Communication，大规模机器类通信)。
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，定义了一个新的RRC状态，即RRC_INACTIVE(RRC非激活态)状态。这种状态有别于RRC_IDLE(RRC空闲态)和RRC_CONNECTED(RRC连接态)状态。
RRC_IDLE(简称为“IDLE状态”或“空闲态”)：移动性为基于UE的小区选择重选，寻呼由CN(Core Network，核心网)发起，寻呼区域由CN配置。基站侧不存在UE AS(Access Stratum，接入层)上下文。不存在RRC连接。
RRC_CONNECTED(简称为“CONNECTED状态”或“连接态”)：存在RRC连接，基站和UE存在UE AS上下文。网络侧知道UE的位置是具体小区级别的。移动性是网络侧控制的移动性。UE和基站之间可以传输单播数据。
RRC_INACTIVE(简称为“INACTIVE状态”或“非激活态”)：移动性为基于UE的小区选择重选，存在核心网与RAN之间的连接，UE AS上下文存在锚点基站上，寻呼由RAN触发，基于RAN的寻呼区域由RAN管理，网络侧知道UE的位置是基于RAN的寻呼区域级别的。
2.NB-IoT(Narrow Band Internet of Things，窄带物联网)非连接态UE的RRM(Radio Resource Management，无线资源管理)测量
处于非连接态的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。
非连接态的UE针对服务小区测量是持续进行的。在相关技术的NB-IoT中，引入了针对静止UE的邻小区测量放松机制，以进一步满足UE省电的需求。针对邻小区测量放松引入了测量放松准则，网络会配置NRSRP(Narrowband Reference Signal Received Quality，窄带参考信号接收功率)变化的评估时长TSearchDeltaP和RSRP(Reference Signal Received Quality，参考信号接收功率)变化值门限SSearchDeltaP。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。即：在一段时间TSearchDeltaP内，满足：
(SrxlevRef–Srxlev)<SSearchDeltaP<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，
如果(Srxlev-SrxlevRef)>0，或者，
如果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；
UE在完成小区选择或重选之后，需要在至少一段时间TSearchDeltaP内执行正常的RRM测量。
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。
3.NB-IoT连接态UE的RRM测量
在一些相关技术中，NB-IoT UE不支持连接态的RRM测量。当连接态的NB-IoT UE在服务小区上的信道质量变差后，通过RLF(Radio Link Failure，无线链路失败)和RRC重建过程来进行移动性管理。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。
为了节省UE触发RLF之后选择重建小区的时间，相关技术针对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-measure准则，同时网络还可以配置UE移动状态评估准则。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 Ref设置为最近一次测得的用于小区选择或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T326定时器。
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T326定时器。
如果网络没有配置UE移动状态评估准则，或者T326定时器正在运行：
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。
4.NR NTN针对earth-fixed cell(地球固定小区)引入的非连接态测量控制
NR NTN中，当服务小区属于Quasi-Earth-fixed cell(准地球固定小区)场景时，引入了基于位置信息和时间信息的邻区测量启动。具体的，基于位置信息的邻区测量启动机制引入了distanceThresh参数，当UE和服务小区参考点(例如小区中心)之间的距离小于distanceThresh时，UE可以停止邻区测量，否则，UE就要执行邻区测量。基于时间信息的邻区测量启动机制引入了t-Service，代表服务小区停止服务的时刻，如果网络配置了该参数，UE需要在t-Service前开始执行同频或异频或异系统的邻区测量，无论位置或RSRP/RSRQ(Reference Signal Receiving Quality，参考信号接收质量)是否满足对应的启动条件。
NR NTN中，对于准地面静止小区场景(也即Quasi-Earth-fixed cell场景)，由于NTN小区的覆盖在一段时间内相对地面是静止的，因此网络可以在系统消息中配置一个相对固定的小区参考点(例如小区覆盖中心点)以及一个固定的小区服务结束时刻。然而，对于earth-moving cell(地球移动小区)场景，NTN小区的覆盖随着卫星移动相对地面一直在移动，其地面参考点(即小区中心点)也随着卫星移动而移动，这样就增加了系统消息配置小区中心点的复杂度，需要考虑其时变的特性。其次，earth-moving cell的停止服务时刻不再是一个统一的时刻，而是针对不同的地理位置而不同，系统消息是面向小区内的所有UE来广播的，因而无法简单的实现针对不同位置配置不同的停止服务时刻。本申请旨在针对earth-moving cell场景研究邻区测量的启动机制，该问题适用于NR NTN和IoT NTN，适用于连接态、空闲态和非激活态的UE。
下面，将通过几个实施例对本申请技术方案进行介绍说明。
请参考图3，其示出了本申请一个实施例提供的邻小区测量方法的流程图。该方法可应用于图1或图2所示的任一卫星网络架构中，例如该方法可以由终端设备执行。该方法可以包括如下步骤：
步骤310，若终端设备满足邻区测量启动条件，则终端设备对邻小区启动或执行测量；其中，邻区测量启动条件与第一信息和/或第二信息有关，第一信息包括与终端设备和卫星之间的距离和/或时延相关的信息，第二信息包括与测量启动时间相关的信息。其中，与终端设备和卫星之间的距离相关的信息，可以理解为与位置相关的信息，即与终端设备的位置和卫星的位置相关的信息。
邻区测量启动条件是指用于触发启动或执行邻区测量的条件。若终端设备满足邻区测量启动条件，则终端设备对邻小区启动或执行测量。其中，启动测量可以理解为开始执行针对邻小区的测量流程。
终端设备所处的卫星网络架构，可以是如图1所示的透明转发的架构，也可以是如图2所示的再生转发的架构，本申请对此不作限定。
在邻区测量启动条件与第一信息有关，且第一信息包括与终端设备和卫星之间的距离和/或时延相关的信息时，本申请实施例提供的邻区测量启动控制方案，可以理解为是基于位置(location-based)或时延的邻区测量启动机制。在邻区测量启动条件与第二信息有关，且第二信息包括与测量启动时间相关的信息时，本申请实施例提供的邻区测量启动控制方案，可以理解为是基于时间信息的邻区测量启动机制。
在一些实施例中，第一信息包括以下至少之一：
a)终端设备到卫星的仰角；
b)终端设备到卫星的距离；
c)终端设备到卫星的传播时延；
d)终端设备的TA(Timing Advance，定时提前量)。
终端设备到卫星的仰角，是指该终端设备与卫星之间的连线与水平面的夹角。示例性地，如图4所示，终端设备41到卫星45的仰角为α，终端设备42到卫星45的仰角为β。终端设备到卫星的仰角能够反映出终端设备和卫星之间的距离。一般来说，终端设备到卫星的仰角越小，说明终端设备和卫星之间的距离越大；反之，终端设备到卫星的仰角越大，说明终端设备和卫星之间的距离越小。示例性地，如图4所示，α＞β，L1＜L2，其中，L1表示终端设备41与卫星45之间的距离，L2表示终端设备42与卫星45之间的距离。
终端设备到卫星的距离，是指该终端设备与卫星之间的连线的长度。示例性地，如图4所示，L1表示终端设备41与卫星45之间的距离，L2表示终端设备42与卫星45之间的距离，从图中可以看出，L1＜L2。
终端设备到卫星的传播时延，可以是单向传播时延，也可以是双向传播时延。其中，单向传播时延可以是信息从终端设备发出，到卫星接收到该信息所经历的时长；或者，单向传播时延也可以是信息从卫星发出，到终端设备接收到该信息所经历的时长。双向传播时延则是信息从终端设备发出到卫星接收到该信息所经历的时长，以及信息从卫星发出到终端设备接收到该信息所经历的时长之和。终端设备到卫星的传播时延能够反映出终端设备和卫星之间的距离。一般来说，终端设备到卫星的传播时延越大，说明终端设备和卫星之间的距离越大；反之，终端设备到卫星的传播时延越小，说明终端设备和卫星之间的距离越小。
终端设备的TA也能够反映出终端设备和卫星之间的距离和/或时延。一般来说，终端设备的TA越大，终端设备和卫星之间的距离和/或时延也就越大；反之，终端设备的TA越小，终端设备和卫星之间的距离和/或时延也就越小。终端设备的TA可以是终端设备当前的实际TA，处于连接态的终端设备可以通过开环和/或闭环控制，获取当前的实际TA。需要说明的是，对于图1所示的透明转发的架构，终端设备的TA实际反映的是终端设备与接入网设备之间的传输时延，但是由于终端设备和接入网设备之间的通信是由卫星进行中转的，因此终端设备的TA也能够从一定程度上反映出终端设备和卫星之间的时延和/或距离。对于图2所示的再生转发的架构，由于没有接入网设备的存在，终端设备的TA实际反映的就是终端设备与卫星之间的传输时延，也即能够反映出终端设备和卫星之间的时延和/或距离。
在一些实施例中，邻区测量启动条件包括以下至少之一：
a)仰角小于或等于第一门限值；示例性地，第一门限值可记为alpha-threshold；
b)距离大于或等于第二门限值；示例性地，第二门限值可记为d-threshold；
c)传播时延大于或等于第三门限值；示例性地，第三门限值可记为t-threshold；
d)TA大于或等于第四门限值；示例性地，第四门限值可记为TA-threshold。
如果终端设备到卫星的仰角小于或等于第一门限值，则说明终端设备与当前的服务小区的卫星之间的距离较大，因此触发终端设备对邻小区启动或执行测量。
如果终端设备到卫星的距离大于或等于第二门限值，则说明终端设备与当前的服务小区的卫星之间的距离较大，因此触发终端设备对邻小区启动或执行测量。
如果终端设备到卫星的传播时延大于或等于第三门限值，则也可以说明终端设备与当前 的服务小区的卫星之间的距离较大，因此触发终端设备对邻小区启动或执行测量。
如果终端设备的TA大于或等于第四门限值，则也可以说明终端设备与当前的服务小区的卫星之间的距离较大，因此触发终端设备对邻小区启动或执行测量。
需要说明的是，第一信息和邻区测量启动条件是相对应的。当第一信息包括终端设备到卫星的仰角时，邻区测量启动条件包括该仰角小于或等于第一门限值；当第一信息包括终端设备到卫星的距离时，邻区测量启动条件包括该距离大于或等于第二门限值；当第一信息包括终端设备到卫星的传播时延时，邻区测量启动条件包括该传播时延大于或等于第三门限值；当第一信息包括终端设备的TA时，邻区测量启动条件包括该TA大于或等于第四门限值。另外，第一信息可以包括上述仰角、距离、传播时延和TA中的任意一项或者任意多项的组合；相应地，邻区测量启动条件也包括上述a)至d)中的任意一项或者任意多项的组合。
在一些实施例中，终端设备根据位置信息确定终端设备的位置，根据服务小区广播的星历信息确定卫星的位置，根据终端设备的位置和卫星的位置，确定以下至少之一：仰角、距离、传播时延。其中，上述位置信息可以是GNSS(Global Navigation Satellite System，全球导航卫星系统)位置信息，或者其他类型的定位信息，本申请对此不作限定。在确定出终端设备的位置和卫星的位置之后，即可计算出终端设备到卫星的距离，也可以根据终端设备到卫星的连线与水平面的夹角确定上述仰角，或者将距离除以光速得到终端设备到卫星的单向传播时延。

1)测量的启动时刻；
2)测量的结束时刻。

在一些实施例中，如果第二信息包括测量的启动时刻和结束时刻，那么相当于第二信息包括测量的时间窗，该测量的时间窗包括测量的启动时刻和结束时刻，例如该测量的时间窗是从测量的启动时刻开始，到测量的结束时刻为之的时间区间。例如，该测量的时间窗可以表示为[T1，T2]，T1表示测量的启动时刻，T2表示测量的结束时刻。
在一些实施例中，邻区测量启动条件包括以下至少之一：
1)当前时刻大于或等于测量的启动时刻；
2)当前时刻小于或等于测量的结束时刻。
如果当前时刻大于或等于测量的启动时刻，则满足邻区测量启动条件，终端设备对邻小区启动或执行测量。
如果当前时刻小于或等于测量的结束时刻，则满足邻区测量启动条件，终端设备对邻小区启动或执行测量。
如果当前时刻大于或等于测量的启动时刻，且当前时刻小于或等于测量的结束时刻，则满足邻区测量启动条件，终端设备对邻小区启动或执行测量。
需要说明的是，第二信息和邻区测量启动条件是相对应的。当第二信息包括测量的启动时刻时，邻区测量启动条件包括当前时刻大于或等于测量的启动时刻；当第二信息包括测量的结束时刻时，邻区测量启动条件包括当前时刻小于或等于测量的结束时刻。
示例性地，如图5中的子图(a)所示，如果第二信息包括测量的启动时刻T0，邻区测量启动条件包括当前时刻大于或等于测量的启动时刻T0，那么在T0时刻之前，终端设备不执行邻区测量，从T0时刻开始，终端设备执行邻区测量。
示例性地，如图5中的子图(b)所示，如果第二信息包括测量的时间窗[T1，T2]，邻区测量启动条件包括当前时刻位于上述时间窗之内，那么在T1时刻之前，终端设备不执行邻区测量，从T1时刻开始到T2时刻，终端设备执行邻区测量，然后在T2时刻终端设备结束邻 区测量。
在一些实施例中，测量的启动时刻为：服务小区和距离终端设备最近的邻小区开始有重叠覆盖的时刻；或者，服务小区和目标频点上距离终端设备最近的邻小区开始有重叠覆盖的时刻；或者，服务小区和目标邻小区开始有重叠覆盖的时刻。
如果上述邻区测量启动条件有关的配置信息，是针对每个终端设备配置的，则测量的启动时刻可以是服务小区和距离终端设备最近的邻小区开始有重叠覆盖的时刻。如果上述邻区测量启动条件有关的配置信息，是针对每个频点配置的，则测量的启动时刻可以是服务小区和目标频点上距离终端设备最近的邻小区开始有重叠覆盖的时刻；其中，目标频点可以是任意一个频点。如果上述邻区测量启动条件有关的配置信息，是针对每个邻小区配置的，则测量的启动时刻可以是服务小区和目标邻小区开始有重叠覆盖的时刻；其中，目标邻小区可以是任意一个邻小区。
另外，在本申请实施例中，对终端设备获取当前时刻的方式不作限定，例如终端设备可以通过GNSS或者通过读取SIB(System Information Block，系统信息块)9消息获取当前时刻。
在一些实施例中，终端设备接收服务小区发送的配置信息，该配置信息用于指示与邻区测量启动条件有关的参数。
示例性地，当邻区测量启动条件包括以下至少之一时：a)仰角小于或等于第一门限值；b)距离大于或等于第二门限值；c)传播时延大于或等于第三门限值；d)TA大于或等于第四门限值；相应地，配置信息包括以下至少之一：a)第一门限值；b)第二门限值；c)第三门限值；d)第四门限值。
示例性地，当邻区测量启动条件包括以下至少之一时：1)当前时刻大于或等于测量的启动时刻；2)当前时刻小于或等于测量的结束时刻；相应地，配置信息包括以下至少之一：1)测量的启动时刻；2)测量的结束时刻。
在一些实施例中，上述配置信息是针对每个终端设备配置的，或者针对每个频点配置的，或者针对每个邻小区配置的。也即，配置信息可以结合实际需求，按需进行配置，从而提升邻区测量启动条件配置的灵活性。
在一些实施例中，配置信息通过系统消息发送，或者通过RRC专用信令发送。示例性地，上述系统消息可以是SIB 1消息、SIB 2消息、SIB 19消息等。示例性地，上述RRC专用信令可以是RRC重配置消息。
在一些实施例中，不同类型的邻小区对应相同的邻区测量启动条件。其中，不同类型的邻小区包括以下至少两种：同频邻小区、异频邻小区、异系统邻小区。例如，同频邻小区、异频邻小区和异系统邻小区，对应于同样的邻区测量启动条件。当终端设备满足该邻区测量启动条件时，终端设备对同频邻小区、异频邻小区和异系统邻小区均启动或执行测量。
在一些实施例中，不同类型的邻小区对应不同的邻区测量启动条件。其中，不同类型的邻小区包括以下至少两种：同频邻小区、异频邻小区、异系统邻小区。例如，同频邻小区、异频邻小区和异系统邻小区，分别对应于不同的邻区测量启动条件。当终端设备满足同频邻小区对应的邻区测量启动条件时，终端设备对同频邻小区启动或执行测量。当终端设备满足异频邻小区对应的邻区测量启动条件时，终端设备对异频邻小区启动或执行测量。当终端设备满足异系统邻小区对应的邻区测量启动条件时，终端设备对异系统邻小区启动或执行测量。在这种方式下，可以针对不同类型的邻小区配置不同的邻区测量启动条件，例如根据不同类型邻小区的部署情况，分别设置不同的邻区测量启动条件，从而更具灵活性，且有助于避免终端设备执行一些不必要的邻区测量，节省功耗。
在一些实施例中，若终端设备不满足邻区测量启动条件，则终端设备不执行对邻小区启动或执行测量的步骤，也即终端设备不对邻小区启动或执行测量。

示例性地，如果服务小区的RSRP和RSRQ测量结果均大于或等于网络配置的RSRP门限和RSRQ门限；
(1)如果网络配置了上述与邻区测量启动条件有关的参数，并且终端设备支持上述邻区测量启动机制，且终端设备有可用的或有效的位置信息，该位置信息包括用于确定终端设备的位置的信息(如GNSS信息)，可选地还包括用于确定卫星的位置的信息(如服务小区提供的星历信息)；
(1-1)如果终端设备满足上述邻区测量启动条件，则终端设备对邻小区启动或执行测量；
