However, if the base station sends to the UE in the form of multicast, the base station only needs to establish a dedicated MBMS/MBS bearer, and all UEs interested in the MBMS/MBS service can receive the MBMS/MBS service through the dedicated bearer. Therefore, the way that the base station adopts MBMS/MBS dedicated bearer to multicast and send data to the UE can save air interface resources, improve frequency spectrum utilization, and improve transmission efficiency.

Description

一种测量方法及相关装置
本申请要求于2021年7月16日提交中国国家知识产权局、申请号为202110808492.7、申请名称为“一种测量方法及相关装置”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
本申请涉及通信技术领域，尤其涉及一种测量方法及相关装置。
背景技术
移动性管理是无线移动通信中的一项基本功能，用于保证网络设备与用户设备(user equipment，UE)之间的通信链路不因UE的移动而中断的服务。根据UE的无线资源控制(radio resource control，RRC)状态可将移动性管理分为空闲态移动性管理和连接态(radio resource control connected state，RRC_CONNECTED state)移动性管理。RRC空闲态移动性管理包括小区选择/重选(cell selection/reselection)的过程。RRC连接态移动性管理包括小区切换(handover)的过程。终端设备进行移动性管理(比如，小区选择/重选，或者切换)时，需要获取测量结果，进而基于测量结果进行移动性管理。
目前，UE接收单播业务时，RRC连接态的UE可根据服务小区的测量配置，对服务小区进行测量，从而UE或网络设备根据一个小区(例如服务小区)的测量参考信号的测量结果对该UE进行RRC连接态移动性管理。然而，在引入多播传输技术后，UE可以通过多播方式接收多个小区(例如，服务小区和单频网络(single frequency network，SFN)动态小区)传输的多播业务，此种情形下，如何进行移动性管理仍需进一步的研究。
发明内容
本申请实施例提供了一种测量方法及相关装置，用以实现更为可靠的移动性管理。
第一方面，本申请实施例提供一种测量方法。该方法可由第一通信装置执行，第一通信装置可以是通信设备或能够支持通信设备实现该方法所需的功能的通信装置，例如芯片。示例性地，该第一通信装置为终端设备，或者为设置在终端设备中的用于实现终端设备的功能的芯片，或者为用于实现终端设备的功能的其他部件。在下文的介绍过程中，以第一通信装置是终端设备为例进行说明。
该方法中，终端设备根据测量配置信息，确定多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，该测量配置信息包括多播小区测量参考信号和单小区测量参考信号的测量信息。终端设备根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，确定触发测量配置信息中的测量事件；或者，根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，确定不触发测量配置信息中的测量事件。
可见，终端设备根据测量配置信息确定的多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，确定是否触发测量配置信息中的测量事件，使得终端设备触发测量事件更加准确；另一方面，该方法可使得终端设备在确定触发测量事件时，通过测量报告上 报多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，可以减少网络设备根据传统的单小区测量参考信号的测量结果，确定终端设备是否需要进行小区切换所导致的移动性管理可靠性较低的问题，因此，本申请可实现更为可靠的移动性管理。
一种可选的实施方式中，多播小区参考信号包括单频网络(single frequency network，SFN)测量参考信号或多播专用测量参考信号。例如，当多个小区协作以SFN的方式广播数据给终端设备时，多播小区测量参考信号包括SFN测量参考信号。再例如，当多小区协作以多播方式传输数据给终端设备时，多播小区测量参考信号包括多小区的多播专用测量参考信号。
如此，网络设备可以根据多小区实际的组网形式、和/或传输数据的方式(例如，广播、多播)使用合适的多播小区测量参考信号，提高了网络设备配置多播小区测量参考信号的灵活性。
一种可选的实施方式中，测量配置信息还包括一个或多个权重系数，以及第一门限；此时，终端设备根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，确定触发测量配置信息中的测量事件，包括：终端设备根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，以及一个或多个权重系数，确定加权后的测量结果；在加权后的测量结果满足第一门限时，确定触发第一门限对应第一测量事件。
可见，当测量配置信息包括一个或多个权重系数，以及第一门限时，终端设备是根据加权后的测量结果，确定是否触发第一门限对应的第一测量事件。即终端设备联合了多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，确定是否触发测量事件，可提高终端设备确定触发测量事件的准确性。
另一种可选的实施方式中，测量配置信息还包括第二门限和第三门限，终端设备根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，确定触发测量配置信息中的测量事件，包括：终端设备在多播小区测量参考信号的测量结果满足第二门限，以及单小区测量参考信号的测量结果满足第三门限时，确定触发第二门限和第三门限对应的第二测量事件。
可见，终端设备在测量配置信息包括第二门限和第三门限时，当多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果分别满足第二门限和第三门限时，确定触发第二门限和第三门限对应的第二测量事件。即终端设备也是联合了多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，确定是否触发第二测量事件的，进而也可提高终端设备确定触发测量事件的准确性。
又一种可选的实施方式中，测量配置信息还包括第二门限和/或第三门限，终端设备根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，确定触发测量配置信息中的测量事件，包括：终端设备在多播小区测量参考信号的测量结果满足第二门限时，或者在单小区测量参考信号的测量结果满足第三门限时，确定触发第二门限和第三门限对应的第二测量事件。
可见，终端设备在测量配置信息包括第二门限和/或第三门限时，当多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果中的一个测量结果满足测量结果对应的门限时，确定触发第二测量事件，进而上报测量报告。与上述终端设备在多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果分别满足第二门限和第三门限时，才确定触发第二测量事件相比，该方式可使得网络设备获得更多的测量报告，有利于网络设备能够根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，进行更及时的移动性管理。
一种可选的实施方式中，当终端设备根据加权后的测量结果确定触发第一测量事件时，终端设备上报测量报告，该测量报告包括加权后的测量结果。
可见，若终端设备根据加权后的测量结果确定触发上述第一测量事件，那么终端设备上报的也是加权后的测量结果，以使得网络设备根据加权的测量结果确定终端设备是否需要进行小区的切换。
另一种可选的实施方式中，若终端设备根据多播小区测量参考信号的测量结果和/或单小区测量参考信号的测量结果，确定触发上述第二测量事件，那么终端设备上报测量报告，该测量报告包括多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果。
可见，即使终端设备根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果中的其中一个测量结果，确定触发上述第二测量事件，终端设备上报的也是多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，以使得网络设备根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，确定终端设备是否需要进行小区的切换，进而有利于实现更为可靠的移动性管理。
一种可选的实施方式中，终端设备在上报测量报告时，还可启动定时器，并在该定时器计时期间，不进行测量报告的生成。
可见，终端设备在上报测量报告期间，即使其他测量结果触发了对应的测量事件，终端设备也不再进行新的测量报告的生成，以提高当前测量报告上报的成功率。

具体实施方式
下面结合本申请实施例中的附图对本申请实施例中的技术方案进行清楚、完整的描述。
首先，为了更好的理解本申请实施例公开的测量方法，对本申请实施例适用的通信系统进行描述。

本申请实施例的技术方案可应用于各种通信系统中。例如，第四代移动通信(4th-generation，4G)系统和第五代移动通信(5th-generation，5G)系统、以及随着通信技术的不断发展。本申请实施例的技术方案还可用于第六代移动通信(6th-generation，6G)系统等后续演进的通信系统，等等。
本申请实施例中，终端设备可以是用户设备(user equipment，UE)、接入终端、UE单元、UE站、移动站、移动台、远方站、远程终端、移动设备、UE终端、终端、无线通信设备、多媒体设备、流媒体设备、UE代理或UE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、可穿戴设备、未来5G网络中的终端，或者未来演进的公共陆地移动网络(public land mobile network，PLMN)网络中的终端等。

本申请实施例中的术语“系统”和“网络”可被互换使用。“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A、同时存在A和B、单独存在B的情况，其中A，B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如“A，B和C中的至少一个”包括A，B，C，AB，AC，BC或ABC。
本申请实施例中，“组播”也可以理解为“多播”、“广播”、“组播广播”；多播小区可以为“组播小区”、“多播广播小区”、“广播小区”“MBS小区”；“单小区”可以理解为“单播小区”。本申请对此不做区分，下文描述中替代使用。
另外，本申请实施例中，多播小区可以理解为进行多播业务的小区，单小区可以理解为进行单播业务的小区，本申请对此不做限制。其次，对本申请实施例涉及的相关概念进行简单的介绍。
1.多媒体广播多播业务(multimedia broadcast multicast service，MBMS)、组播/多播广播业务(multicast broadcast service，MBS)。
如图2所示，MBMS或者MBS主要是面向多个UE的业务，即基站同时将MBMS业务或MBS业务向多个UE发送。例如，现场直播、定时播放节目等。基站可以建立UE专用的承载，并通过该UE专用的承载以单播(unicast)的形式将MBMS/MBS业务发送给UE。基站也可以建立MBMS/MBS业务专用的承载，通过MBMS/MBS业务专用的承载以多播(multicast)的形式将MBMS/MBS业务发送给UE。
当有大量UE需要接收某一MBMS/MBS业务时，若基站以单播形式发送此业务给大量UE，那么基站需要为大量的UE建立专用承载，该方式会造成大量的资源消耗。然而，若基站是以多播的形式发送给UE，则基站只需要建立MBMS/MBS专用的承载，所有对该MBMS/MBS业务感兴趣的UE均可以通过该专用的承载接收MBMS/MBS业务，因此基站采 用MBMS/MBS专用的承载给UE多播发送数据的方式可节约空口资源，提高频谱利用率，以及提高传输效率。
2.单频网络(single frequency network，SFN)。
单频网络是实现上述多播传输的一种方式，即多个小区的网络设备通过单频网络的方式向UE多播传输数据。该传输方式中的多个小区被称为SFN动态小区，如图3所示，灰色区域是SFN动态小区，该SFN动态小区的范围是根据UE的位置改变而变化的。在SFN动态小区中的每个小区均是使用相同的数据包传输模式(packet transmission mode，PTM)，均配置有相同的时频资源，且向UE传输相同的数据。
3.UE的工作状态。
在4G系统中，根据无线资源控制(radio resource control，RRC)的连接状态，将UE的工作状态分为RRC连接态和RRC空闲态。UE在开机但并未与无线网络建立连接时，处于RRC空闲态。UE与无线网络建立连接时，处于RRC连接态。相比4G系统，5G系统中也保留了RRC空闲态和RRC连接态。除此之外，5G还新增一个第三态，即RRC inactive态。UE可在RRC的这三个状态之间相互转换。
UE处于RRC连接态时，可以进行数据的收发，并可根据UE自身的活动性，进行非连续接收(discontinuous reception，DRX)，从而可节省空口资源以及UE的耗电。UE处于RRC空闲态(RRC_IDLE)时，UE不存在RRC连接。此时UE可进行小区选择和重选，监听寻呼信道，跟踪区更新(tracking area update，TAU)等。RRC inactive态(RRC_INACTIVE)可使UE快速恢复到RRC连接态。
4.UE的移动性管理、移动性测量。
移动性管理是无线移动通信中的一项基本功能，用于保证网络设备与UE之间的通信链路不因UE的移动而中断的服务。根据UE的状态可将移动性管理分为无线资源控制空闲态(radio resource control idle state，RRC_IDLE state)移动性管理和无线资源控制连接态(radio resource control connected state，RRC_CONNECTED state)移动性管理两部分。RRC空闲态移动性管理包括小区选择/重选(cell selection/reselection)的过程。RRC连接态移动性管理包括进行小区切换(handover)的过程。终端设备进行移动性管理(比如，小区选择/重选，或者切换)时，需要获取测量结果，进而基于测量结果进行移动性管理。
通信系统中，根据测量所涉及到的层次，移动性测量可以被划分为物理层测量(层1测量)和RRC层测量(层3测量)两部分。
5.RRC层测量。
目前，RRC层测量包括：测量配置、测量执行、测量上报。
测量配置是网络设备给UE配置的，且用于UE在RRC连接态时对服务小区进行测量的配置。测量配置的相关信息一般通过RRC重配置消息传递给UE。例如，长期演进(long term evolution，LTE)系统中，eNB通过RRCConnectionReconfigurtion消息携带的measConfig信元将测量配置下发给UE。再例如，NR系统中，gNodeB通过RRCReconfigurtion消息携带的measConfig信元将测量配置下发给UE。
测量执行是指UE根据测量配置对当前服务小区进行测量。另外，UE会根据RRCConnectionReconfigurtion消息中的s-Measure信元或者RRCReconfigurtion消息中的s-MeasureConfig信元来判断是否需要执行对相邻区的测量，若需要对邻区进行测量时，UE还会根据测量配置对邻区进行测量。
测量报告是基于测量对象(比如，同步信号块(synchronization signal block，SSB)/物理 广播信道块(physical broadcast channel block，PBCH block)，信道状态信息参考信号(channel state information reference signal，CSI-RS)的测量结果获得的。测量报告的上报触发方式按照类型分为事件触发上报和周期触发上报。事件触发上报是指测量结果满足测量报告的上报条件时，UE将测量结果填入MeasurementReport消息中，并将该MeasurementReport消息发送给网络设备，比如eNB/gNB。如图4所示，终端设备通过MeasurementReport消息将测量报告上报给网络设备。
其中，事件触发的上报配置中包括各类事件及门限值。当对应的测量事件满足触发条件的持续时间(time To Trigger)，以及参考信号的类型(SSB或CSI-RS)等等时，终端设备确定触发对应的测量事件。以下表1为各类测量事件的定义，以及进入条件和离开条件。
表1
Figure PCTCN2022101457-appb-000001
上述表1中，Ms代表服务小区信号质量，Mn代表邻区信号质量，Hys代表服务小区对应的偏移，Thresh代表门限，Ofn和Ocn代表邻区对应的偏置，Ofs和Ocs代表服务小区对应的偏置。TimeToTriger代表持续时间。
按照准则可将上述的事件触发上报和周期触发上报细分为：事件触发的一次上报、事件触发的周期上报、周期性上报。网络设备在测量配置中配置了UE上报测量报告的方式，即 网络设备在RRC重配置消息里的MeasConfig中的ReportConfigToaddModlist中配置了UE上报测量报告的方式。
事件触发的一次上报：是指UE仅当满足了某个测量事件的进入门限，并持续一段时间(timeToTrigger)后，才会触发测量报告的发送，且测量报告发送一次后，发送流程结束。此时测量配置的上报配置为：报告类型为“事件”，即reportType＝eventTriggered；上报次数为一次，即reportAmount＝1；上报间隔无论为何值，UE均会忽略，即忽略reportInterval的值。
事件触发的周期上报：是指UE仅当满足了某个测量事件的进入门限，并持续一段时间(timeToTrigger)后，才会触发测量报告的发送。上报被触发后，会开启多次测量之间的定时器(reportInterval)以及测量次数的计数器(reportAmount)，直至上报次数达到要求后，上报流程结束。如果reportAmount为infinity，则UE会一直周期上报。此时测量配置的上报配置为：报告类型为“事件”，即reportType＝eventTriggered；上报次数大于一次，即reportAmount〉1；上报间隔有效，即UE将根据上报间隔reportInterval来设置上报周期的定时器。
周期性上报：UE按照测量配置的上报配置中的上报周期和上报间隔(reportInterval)发送测量报告。此时测量配置的上报配置为：报告类型为“周期”，即reportType＝periodical；上报次数大于一次，即reportAmount〉1。
终端设备上报的测量报告主要包括测量标识(measure identification，MeasID)，服务小区测量量(measResultServingMOList)、邻区测量量(measResultNeighCells)。
其中，网络设备通过测量标识和自身存储的测量配置可以获取本次上报所对应的测量对象标识(identification，ID)和上报配置ID，事件触发的测量事件门限、周期触发目的等内容。
服务小区测量量包含物理小区ID、小区测量量的结果(如参考信号接收功率(reference signal received power，RSRP)、参考信号的测量结果(如针对单个SSB的测量结果)等。
邻区测量量包括物理小区ID、邻区对应的触发量、小区标识等。
再次对本申请所要解决的技术问题进行简单的描述。
目前，UE接收单播业务时，RRC连接态的UE可根据服务小区的测量配置，对服务小区进行测量，从而UE或网络设备根据一个小区(服务小区)的测量参考信号的测量结果对该UE进行RRC连接态移动性管理。而UE在同时接收多播业务(如通过SFN实现的多播业务)和单播业务时，UE接收的是多个小区(服务小区和SFN动态小区)传输的数据，此时RRC连接态的UE无法通过目前服务小区的测量配置完成对服务小区和SFN动态小区的测量，从而UE或网络设备无法完成对该UE的RRC连接态移动性管理。因此，此种情形下，如何进行移动性管理仍需进一步的研究。
本申请实施例提供了一种测量方法100。该测量方法100中，终端设备根据测量配置信息，确定多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，该测量配置信息包括多播小区测量参考信号和单小区测量参考信号的测量信息；终端设备根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，确定触发测量配置信息中的测量事件；或者，根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，确定不触发测量配置信息中的测量事件。终端设备是根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，确定是否触发测量配置信息中的测量事件，使得终端设备触发测量事件更加准确。另一方面，该方法可使得终端设备在确定触发测量事件时，通过测量报告上报多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，可以减 少网络设备根据传统的单小区测量参考信号的测量结果，确定终端设备是否需要进行小区切换所导致的移动性管理可靠性较低的问题，因此，该方法可实现更为可靠的移动性管理。
本申请实施例还提供了一种测量方法200。与上述测量方法100不同的是，终端设备确定多播小区测量参考信号的测量结果和及单小区测量参考信号的测量结果后，根据测量配置信息中的上报周期，周期性上报测量报告。该方式中，终端设备上报的测量报告是根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果生成的，从而使得网络设备不是根据传统的单小区测量参考信号的测量结果确定终端设备是否需要进行小区切换，而是根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，确定终端设备是否需要进行小区切换，从而可实现更为可靠的移动性管理。
本申请实施例还提供了一种测量方法300。与上述测量方法100和测量方法200不相同的是，终端设备在确定出多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果后，自行根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果确定待切换的目标小区，以及向目标小区发起随机接入，完成移动性管理。由于目标小区不是根据传统的单小区测量参考信号的测量结果确定的，而是根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果确定的，因此也可实现更为可靠的移动性管理。
本申请实施例所提供的测量方法适用于对多个小区进行测量，例如，适用于对单小区和多播小区进行测量。
本申请实施例提供一种测量方法100。图5是该测量方法100的交互示意图。该测量方法100是从终端设备和网络设备之间交互的角度进行阐述。该测量方法100包括但不限于以下步骤：
S101.终端设备根据测量配置信息，确定多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，测量配置信息包括多播小区测量参考信号和单小区测量参考信号的测量信息。
一种可选的实施方式中，网络设备与终端设备建立专用连接，网络设备确定上述测量配置信息，并将该测量配置信息通过专用链接下发给终端设备，从而终端设备接收来自网络设备的测量配置信息。
另一种可选的实施方式中，网络设备与终端设备无需建立连接，网络设备可以通过广播、多播、或者系统信息块(system information block，SIB)告知终端设备，此时，终端设备接收多播、广播或者SIB信息，获取测量配置信息。也就是说，上述多播、广播或者SIB信息中包括测量配置信息，终端设备通过接收该广播、多播或者SIB信息，获取测量配置信息。
本申请实施例中，多播小区指的是终端设备接收多播业务/广播业务时所涉及的多个小区。例如，网络设备通过SFN向终端设备传输广播业务，即多个小区的网络设备同时向终端设备广播相同的数据，那么此时终端设备所处的SFN动态小区包括多个小区，该多个小区即为终端设备在接收广播业务时所涉及的多播小区。再例如，多个小区通过协商方式给终端设备传输多播业务，该多个小区也就为终端设备接收多播业务时所涉及的多播小区。单小区是指终端设备接收单播业务时，所在的服务小区。
另外，多播小区测量参考信号是用于对多播小区进行测量的参考信号，单小区测量参考信号是用于对单小区进行测量的参考信号。
多播小区测量参考信号和单小区测量参考信号的测量种类是相同的，即测量的都是参考信号接收功率(reference signal received power，RSRP)，参考信号接收质量(reference signal  received quality，RSRQ)或者信干噪比(signal to interference plus noise ratio，SINR)。测量RSRP时，单位为dBm；测量RSRQ和RS-SINR时，单位为dB。
可选的，多播小区测量参考信号和单小区测量参考信号的测量种类也可是不相同的。
一种可选的实施方式中，多个小区通过协作将广播业务传输给终端设备，终端设备通过接收多个小区的数据，接收该广播业务。也就是说，网络设备通过上述SFN实现广播业务的传输。此时，多播小区测量参考信号包括SFN测量参考信号，该SFN测量参考信号用于对SFN动态小区进行测量。
另一种可选的实施方式中，多个小区通过协作将多播业务传输给终端设备时，终端设备通过接收多个小区的数据，实现对多播业务的接收。此时，该多播小区测量参考信号包括多小区多播专用测量参考信号，该多小区的多播专用测量参考信号用于对传输多播业务的多个小区进行测量。本申请实施例中，多小区和多个小区的含义相同，即多小区代表了多个小区。
不论多播测量参考信号包括上述哪一种测量参考信号，多播测量参考信号均包括以下一种或多种：多播测量参考信号的种类(比如，SSB，CSI-RS，或者信定义的与多播小区相匹配的参考信号)，多播测量参考信号占用的时域资源(周期、偏置、占用长度、重复次数、重复间隔、用于确定多播测量参考信号出现的时域位置和占用的时域长度，单位可为子帧，或者为符号)，频域资源(多播测量参考信号所在的频点资源、多播测量参考信号使用的频域资源数、子载波间隔、comb结构)，码域资源(初始码序列)，空域资源(与其他参考信号的准共址(Quasi Co-Location，QCL)关系)。
一种可选的实施方式中，多播测量参考信号是多播小区对应的多个网络设备通过协商确定的。也就是说，多个网络设备通过协商分布式确定采用哪一个参考信号作多播测量参考信号。
另一种可选的实施方式中，多播小区测量参考信号是第一小区中的网络设备确定的，第一小区是多播小区中的任一小区。也就是说，多播小区对应的多个网络设备中的其中一个网络设备确定采用哪一个参考信号作为多播测量参考信号，并将确定的多播测量参考信号下发给多播小区对应的所有网络设备。该网络设备可以是CN网元，也可以是某个RAN节点。
另外，多播小区测量参考信号和单小区测量参考信号的测量信息是指多播小区测量参考信号的测量信息和单小区测量参考信号的测量信息。多播小区测量参考信号的测量信息和单小区测量参考信号的测量信息，可以是网络设备同时发送给终端设备的。例如，多播小区测量参考信号的测量信息和单小区测量参考信号的测量信息包含在相同的专用信令中，如RRC重配置或RRCResume消息。或者，多播小区测量参考信号的测量信息和单小区测量参考信号的测量信息是网络设备分开发送给终端设备的。例如，在终端设备加入多播会话的过程中，网络设备将多播小区测量参考信号的测量信息作为多播配置的一部分通过专用信令下发给终端设备，而网络设备则使用其他专用信令(如RRC重配置消息)下发给终端设备。
一种可选的实施方式中，多播小区测量参考信号的测量信息包括以下一种或多种：多播小区测量参考信号的频点信息，子载波间隔，多播小区测量参考信号的配置。
一种可选的实施方式中，测量配置信息还包括上报配置，上报配置包括以下一种或多种：多播测量参考信号的种类(比如，SSB，CSI-RS，或者信定义的与多播小区相匹配的参考信号)，终端设备需要上报的测量报告的数量，终端设备执行周期上报时使用的上报间隔，包含在测量报告中的测量结果的测量类型(RSRP、RSRQ、SINR)，测量报告中包含的最大的非服务小区的数量，多播小区测量中被测量的合并小区数量，测量事件相关信息。
其中，测量事件相关信息包括以下一种或多种：事件阈值参数(MeasTriggerQuantity)和偏移量参数(MeasTriggerQuantityOffset)，滞后参数(hysteresis)，触发时间(TimeToTrigger)，用于定义符合该事件的进入条件和离开条件。
可理解的，终端设备根据测量配置信息，对多播小区测量参考信号和单小区测量参考信号分别进行测量，从而确定多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果。
S102.终端设备根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，确定触发测量配置信息中的测量事件；或者，根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，确定不触发测量配置信息中的测量事件。
可理解的，测量配置信息中还包括测量事件，该测量事件与终端设备是否上报测量报告相关联。测量报告是根据多播测量参考信号的测量结果和单小区测量参考信号的测量结果确定的。当终端设备确定触发该测量事件时，上报测量报告；当终端设备确定不触发测量事件时，不上报测量报告。从而，终端设备可根据确定的多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，确定是否触发该测量事件，以进一步确定是否上报测量报告。
以下结合测量配置信息的三种实施方式，阐述终端设备根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，确定是否触发测量事件的实施方式：
方式1：测量配置信息包括一个或多个权重系数，以及第一门限时。
可以理解，在此方式下，终端设备根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，一个或多个权重系数，以及第一门限，确定是否触发测量事件。
其中，一个或多个权重系数用于终端设备结合多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果生成加权后的测量结果。
可选地，权重系数是根据以下一种或多种确定的：多播小区传输的业务的优先级、单小区传输的业务的优先级、多播小区传输的业务的服务质量标识符或单小区传输的业务的服务质量标识符。可例如，权重系数是根据多播小区传输的业务的优先级确定的。再例如，权重系数是根据单小区传输的业务的优先级确定的。再例如，权重系数是根据多播小区传输的业务的优先级和单小区传输的业务的优先级确定的。再例如，权重系数是根据多播小区传输的业务的服务质量标识符确定的。再例如，权重系数是根据单播小区传输的业务的服务质量标识符确定的。再例如，权重系数是根据多播小区传输的业务的服务质量标识符和单小区传输的业务的服务质量标识符确定的。再例如，权重系数可以由多播小区传输的业务的优先级和多播小区传输的业务的服务质量标识符确定的。本申请对此不做限制。
一种可选的实施方式中，当测量配置信息配置的测量事件不涉及对邻区的测量时，多播小区测量参考信号对应的第一权重系数与单小区测量参考信号对应的第二权重系数之间存在归一化的关系。网络设备可以配置其一，终端设备根据归一化关系确定另一个权重系数；或者网络设备可以根据归一化关系确定两个权重系数，然后发给终端设备。可以理解，当第一权重系数和第二权重系数之间存在归一化的关系时，第一权重系数和第二权重系数之和为1。
例如，当测量配置信息包括多播测量参考信号对应的第一权重系数和单小区测量参考信号对应的第二权重系数时，第一权重系数和第二权重系数分别是根据多播小区传输的业务的优先级、单小区传输的业务的优先级确定的。比如，多播小区传输的业务的优先级为第3级，单小区传输的业务的优先级为第7级，网络设备确定第一权重系数等于0.3，第二权重系数等于0.7。
再例如，当测量配置信息包括多播测量参考信号对应的第一权重系数时，第一权重系数是根据多播小区传输的业务的优先级确定的。比如，多播小区传输的业务的优先级和单小区传输的业务的优先级共有10级，多播小区传输的业务的优先级为第2级，网络设备确定第一权重系数为0.2。终端设备获得第一权重系数为0.2后，根据第一权重系数，确定第二权重系数等于1-第一权重系数，即第二权重系数为0.8。可见，第一权重系数和第二权重系数具有归一化关系。当测量配置信息包括一个权重系数时，终端设备可根据测量配置信息包括的权重系数和归一化原则，确定另外一个权重系数，进而根据多播小区测量参考信号和单小区测量参考信号分别对应的权重系数确定加权后的测量结果。
另一种可选的实现方式中，当测量配置信息配置的测量事件涉及对邻区(neighbour cells)的测量时，测量配置信息还包括邻区测量参考信号对应的第三权重系数和第四权重系数，第三权重系数是单小区相关的邻区测量参考信号对应的权重系数，第四权重系数是多播小区相关的邻区测量参考信号对应的权重系数。
又一种可选的实现方式中，当测量配置信息的测量事件涉及邻区的测量时，测量配置信息还包括邻区测量参考信号对应的第三权重系数，且终端设备接收到测量配置信息后，可根据归一化原则和第三权重系数，确定出邻区测量参考信号对应的第四权重系数，即第四权重系数＝1-第三权重系数。
又一种可选的实现方式中，当测量配置信息的测量事件涉及邻区的测量时，测量配置信息还包括邻区测量参考信号对应的第四权重系数，且终端设备接收到测量配置信息后，可根据归一化原则和第四权重系数，确定出邻区测量参考信号对应的第三权重系数，即第三权重系数＝1-第四权重系数。
也就是说，网络设备在传输的业务的优先级更为重要，或者QoS要求更为严格时，应当增加测量参考信号对应的权重系数，从而使得后续UE进行移动性管理时，参考的加权后的测量结果更侧重于对传输业务的影响。
一种可选的实施方式中，当终端设备测量的多播小区测量参考信号和单小区测量参考信号的种类是不相同的时，网络设备确定的权重系数需保证根据多播测量参考信号的测量结果和单小区测量参考信号的测量结果进行加权后的测量结果的量纲一致，从而加权后的测量结果才具有可实施性。比如，终端设备测量多播小区测量参考信号测量的是RSRP，测量单播小区测量参考信号测量的是RSRQ，由于RSRP和RSRQ的量纲不相同，调整了多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果中的一个测量结果的量纲，才能根据统一量纲的两个测量结果确定加权后的测量结果。
另外，第一门限是根据多播小区传输的业务的优先级和单小区传输的业务的优先级确定的。可选的，第一门限是根据多播小区传输的业务的服务质量标识符(quality of service identifier，QoS Identifier)和单小区传输的业务的服务质量标识符确定的。也就是说，第一门限的值与小区传输的业务优先级或者传输的业务的服务质量标识符有关。
一种可选的实施方式中，当测量配置信息还包括一个或多个权重系数，以及第一门限时，终端设备根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，确定触发所述测量配置信息中的测量事件，包括：终端设备根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，以及一个或多个权重系数，确定加权后的测量结果；终端设备在加权后的测量结果满足第一门限时，确定触发第一门限对应第一测量事件。
可理解的，当测量配置信息还包括一个或多个权重系数，以及第一门限时，终端设备先确定出加权的测量结果，在加权的测量结果满足第一门限，且持续测量配置信息中的持续时 间(TimeToTriger)时，确定触发第一门限对应的第一测量事件。从而有利于提高网络设备确定终端设备是否进行小区切换的可靠性，进而有利于实现更为可靠的移动性管理。
其中，加权后的测量结果满足第一门限，可指加权后的测量结果大于第一门限，也可指加权后的测量结果小于第一门限。
可选地，当终端设备确定触发第一测量事件时，终端设备将满足第一测量事件进入条件的多播小区和单小区加入到测量报告的触发小区列表(CellsTriggeredList)中。另外，终端设备在加权的测量结果不满足第一门限对应的门限，且持续TimeToTriger时间时，即满足第一测量事件的离开条件时，将满足离开条件的多播小区和单小区从CellsTriggeredList删除。其中，第一门限对应的门限是根据第一门限和偏移量确定的。
另一种可选的实施方式中，当测量配置信息还包括一个或多个权重系数，以及第一门限时，终端设备根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，确定不触发所述测量配置信息中的测量事件，包括：终端设备根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，以及一个或多个权重系数，确定加权后的测量结果；终端设备在加权后的测量结果不满足第一门限对应的门限时，确定不触发第一门限对应的第一测量事件。
可理解的，当测量配置信息还包括一个或多个权重系数，以及第一门限时，终端设备先确定出加权的测量结果，在加权的测量结果不满足第一门限对应的门限时，且持续TimeToTriger时间时，确定不触发第一门限对应的第一测量事件。
例如，第一测量事件中涉及服务小区的测量，需要检测服务小区的信号质量是否高于第一门限，第一门限为MeasTriggerQuantity，多播小区测量参考信号对应的第一权重为w1，单小区测量参考信号对应的第二权重为w2，多播小区测量参考信号的测量结果为Ms1，单小区测量参考信号的测量结果为Ms2，偏置为hysteresis，持续时间为TimeToTriger，那么第一测量事件如下：当满足Ms-hysteresis〉MeasTriggerQuantity，且持续TimeToTriger时，终端设备确定符合第一测量事件的进入条件，即确定触发第一测量事件，也即将满足进入条件的多播小区和单小区添加到测量报告的CellsTriggeredList中；当满足Ms-hysteresis<MeasTriggerQuantity-Hys，且持续TimeToTriger时，终端设备确定符合第一测量事件的离开条件，即将满足离开条件的多播小区和单小区从CellsTriggeredList中删除，Hys为偏移量，且是被配置在测量配置信息中的。其中，Ms为加权的测量结果，Ms＝f(w1,w2,Ms1,Ms2)，f(.)表示数学函数；比如，Ms＝w1*Ms1+w2*Ms2；本申请对具体的f(.)形式不做限制。
又一种可选的实施方式中，当第一测量事件涉及邻区的信号质量时，测量配置信息还包括第四门限。此时，终端设备在上述加权后的测量结果满足第一门限，邻区的测量结果满足第四门限，且持续时间TimeToTriger时，确定触发第一测量事件。其中，邻区是指与当前单小区相邻的小区，或当前多播小区所包含的小区集合不同的小区集合。
也就是说，所述邻区与当前小区的组成成分不同，所述邻区的组成成分包括单小区和多播小区。例如，当前单小区为X小区，当前多播小区为A小区、B小区和C小区，那么当前小区的测量结果包括X小区、A小区、B小区和C小区的测量结果，而邻区的组成包括单小区(X小区)和多播小区(A小区、B小区、D小区)，从而邻区的测量结果由单小区(X小区)和多播小区(A小区、B小区、D小区)的测量结果组成。或者，邻区的组成包括单小区(Y小区)和多播小区(A小区、B小区、C小区)，从而邻区的测量结果由单小区(Y小区)和多播小区(A小区、B小区、C小区)的测量结果组成。再或者，邻区的组成包括 单小区(Y小区)和多播小区(A小区、B小区、D小区)，从而邻区的测量结果由单小区(Y小区)和多播小区(A小区、B小区、D小区)的测量结果组成。再或者，邻区的组成包括单小区(X小区)和多播小区(A小区、B小区)，从而邻区的测量结果由单小区(X小区)和多播小区(A小区、B小区)的测量结果组成。
需要说明的是，当邻区的组成成分包括多个多播小区时，该多个多播小区可以对应相同的权重系数；或者，该多播小区中的部分可以对应相同的权重系数；或者，该多播小区中的每一个可以有各自的权重系数。例如，邻区的组成成分包括多播小区#1(A小区、B小区、D小区)和多播小区#2(A小区、E小区)，多播小区#1和多播小区#2对应的权重系数相同。再例如，邻区的组成成分包括多播小区#1(A小区、B小区、D小区)、多播小区#2(A小区、E小区)、多播小区#3(B小区、C小区)，多播小区#1和多播小区#2对应的权重系数相同，多播小区#3的权重系数不同于多播小区#1和多播小区#2的权重系数。
例如，如上述，当前服务小区中的单小区为X小区，多播小区为A小区、B小区和C小区，加权后的当前小区的测量结果为：Ms＝w1*Ms1+w2*Ms2，Ms1为X小区使用单小区测量参考信号的测量结果，w1为Ms1对应的权重系数，Ms2为多播小区A小区、B小区、C小区使用多播小区测量参考信号得到的测量结果，w2为Ms2对应的权重系数。当邻区的测量结果由单小区(Y小区)和多播小区(A小区、B小区、C小区)的测量结果组成时，加权后的邻区测量结果为：Mn＝w3*Mn1+w2*Mn2，Mn1为邻区(Y小区)的测量结果，w3为Mn1对应的权重系数，Mn2为邻区包括的多播小区的测量结果。那么，当Ms满足第一门限，Mn1满足邻区对应的第四门限时，且持续时间TimeToTriger时，终端设备确定触发第一门限和第四门限对应的测量事件。
再例如，当邻区的测量结果由单小区(X小区)和多播小区(A小区、B小区、D小区)的测量结果组成时，加权后的邻区测量结果为：Mn＝w1*Mn1+w4*Mn2，Mn1为邻区包括的单小区(X小区)的测量结果，Mn2为邻区(A小区、B小区、D小区)的测量结果，w4为Mn2对应的权重系数。那么，当Ms满足第一门限，Mn满足邻区对应的第四门限时，且持续时间TimeToTriger时，终端设备确定触发第一门限和第四门限对应的测量事件。
再例如，当邻区的测量结果由单小区(Y小区)和多播小区(A小区、B小区、D小区)的测量结果组成时，加权后的邻区测量结果为：Mn＝w3*Mn1+w4*Mn2，Mn1为邻区(Y小区)的测量结果，w3为Mn1对应的权重系数，Mn2为邻区(A小区、B小区、D小区)的测量结果，w4为Mn2对应的权重系数。那么，当Ms满足第一门限，且Mn满足邻区对应的第四门限时，且持续时间TimeToTriger时，终端设备确定触发第一门限和第四门限对应的测量事件。
再例如，当邻区的测量结果由单小区(Y小区)和多播小区(A小区、B小区、D小区)的测量结果组成时，加权后的邻区测量结果为：Mn＝w3*Mn3+(wA*MnA+wB*MnB+wD*MnD)，Mn3为邻区(Y小区)的测量结果，w3为Mn3对应的权重系数，MnA、MnB、MnD分别为邻区中多播小区的A小区、B小区、D小区的测量结果，wA、wB、wD分别为MnA、MnB、MnD对应的权重系数。那么，当Ms满足第一门限，且Mn满足邻区对应的第四门限时，且持续时间TimeToTriger时，终端设备确定触发第一门限和第四门限对应的测量事件。
本申请实施例中，上述网络设备对一个或多个权重系数的设置，不仅适用于第一测量事件中信号质量的计算，还可适用于S-mearsure的判决。
S-measure是包含在测量配置MeasConfig中，作为测量配置的一部分，用于定义一个测量量为RSRP的门限值，控制对非服务小区(即邻区)进行测量。当服务小区质量高于此门限值时，UE无需进行同频、异频、异系统等非服务小区(即邻区)的测量，减少耗电。如果没有配置s-Measure或者配置了s-Measure但是服务小区的RSRP高于这个值，那么UE只会测量服务小区，而不会对其他邻区进行测量。
那么，当测量配置信息包括一个或多个权重系数时，针对S-measure的判决，终端设备也是根据一个或多个权重系数，以及多播小区测量参考信号的测量结果、单小区测量参考信号的测量结果确定加权后的测量结果，再确定加权后的测量结果是否高于用于进行S-measure判决的门限。当终端设备根据加权后的测量结果确定满足进行S-measure判决的门限时，终端设备不进行邻区的测量。
需要说明的是，如上对于S-measure的方法可以作为一个单独的实施例，或者作为可选步骤与本申请中的任一项或多项进行结合，本申请对此不做限制。
方式2.测量配置信息包括第二门限和第三门限。
其中，第二门限和第三门限的确定方式与上述权重系数的确定方式相同，即第二门限和第三门限是根据以下一种或多种确定的：多播小区传输的业务的优先级、单小区传输的业务的优先级、多播小区传输的业务的服务质量标识符或单小区传输的业务的服务质量标识符。不再赘述。
一种可选的实施方式中，当测量配置信息包括第一门限和第二门限时，终端设备根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，确定触发测量配置信息中的测量事件，包括：终端设备在多播小区测量参考信号的测量结果满足第二门限，以及单小区测量参考信号的测量结果满足第三门限时，确定触发第二门限和第三门限对应的第二测量事件。
其中，第二测量事件是由第二门限和第三门限组成的测量事件。例如，第二测量事件为多播小区测量参考信号的测量结果大于第二门限，以及单小区测量参考信号的测量结果大于第三门限。再例如，第二测量事件为多播小区测量参考信号的测量结果小于第二门限，单小区测量参考信号的测量结果大于第三门限。
可理解的，当测量配置信息包括第一门限和第二门限时，终端设备在多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果分别同时满足第二门限、第三门限，且持续TimeToTriger时，确定触发第二测量事件。即终端设备是联合了多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，确定触发第二测量事件的，可提高网络设备确定终端设备是否需要进行小区切换的可靠性，从而有利于实现更为可靠的移动性管理。
其中，多播小区测量参考信号的测量结果满足第二门限，可指多播小区测量参考信号的测量结果大于第二门限，也可指多播小区测量参考信号的测量结果小于第二门限。详细地，多播小区测量参考信号的测量结果满足第二门限的含义是根据第二测量事件确定的。同理，单播小区测量参考信号的测量结果满足第三门限的含义也是根据第二测量事件确定的。
可选的，当测量配置信息包括第二门限和第三门限时，终端设备在多播小区测量参考信号的测量结果满足第二门限时，单小区测量参考信号的测量结果未满足第三门限，但在预设时间后，单小区测量参考信号的测量结果满足第三门限，且持续时间TimeToTriger时，终端设备也确定触发第二测量事件。也就是说，当多播小区测量参考信号的测量结果满足第二门限，单小区测量参考信号的测量结果满足第三门限的时间间隔在预设时间内，终端设备就可确定触发第二测量事件。预设时间可以是终端设备预先设定的。
本申请实施例中，当终端设备确定触发第二测量事件时，终端设备将满足第二测量事件进入条件的多播小区和单小区加入到测量报告的CellsTriggeredList中。另外，终端设备在多播小区测量参考信号的测量结果不满足第二门限对应的门限，或者单小区测量参考信号的测量结果不满足第三门限对应的门限，且持续TimeToTriger时间时，即满足第二测量事件的离开条件时，将满足离开条件的多播小区和单小区从CellsTriggeredList删除。其中，第二门限对应的门限是根据第一门限和偏移量确定的，第三门限对应的门限是根据第三门限和偏移量确定的。
另一种可选的实施方式中，终端设备根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，确定不触发测量配置信息中的测量事件，包括：终端设备在多播小区测量参考信号的测量结果不满足第二门限，或者单小区测量参考信号的测量结果不满足第三门限时，确定不触发第二门限和第三门限对应的第二测量事件。
可理解的，当测量配置信息包括第一门限和第二门限时，终端设备在多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果中的一个不满足对应的门限，且持续TimeToTriger时，确定不触发第二测量事件。
例如，第二测量事件中涉及服务小区的测量，需要检测服务小区的信号质量是否高于对应的门限，与多播小区测量参考信号关联的第一门限为MeasTriggerQuantity1，与单小区测量参考信号关联的第二门限为MeasTriggerQuantity2，多播小区测量参考信号的测量结果为Ms1，单小区测量参考信号的测量结果为Ms2，多播小区测量参考信号对应的偏置为hysteresis1，单小区测量参考信号对应的偏置为hysteresis2。那么，第二门限和第三门限对应的第二测量事件如下：当满足Ms1-hysteresis1〉MeasTriggerQuantity1，Ms2-hysteresis2〉MeasTriggerQuantity2，且持续时间TimeToTriger时，终端设备确定符合第二测量事件的进入条件，即确定触发第二测量事件,将满足进入条件的多播小区和单小区添加到测量报告的CellsTriggeredList中；当满足Ms1-hysteresis1<MeasTriggerQuantity1-Hys1，或者满足Ms2-hysteresis2<MeasTriggerQuantity2-Hys2，且持续时间TimeToTriger时，终端设备确定符合第二测量事件的离开条件，将满足离开条件的多播小区和单小区从CellsTriggeredList中删除。其中，Hys1、Hys2为偏移量。
又一种可选的实施方式中，当第二测量事件涉及邻区的信号质量时，测量配置信息还包括第四门限。此时，终端设备在多播小区测量参考信号满足第二门限，单小区测量参考信号满足第三门限，以及邻区测量参考信号的测量结果满足第四门限时，确定触发第二测量事件。
上述对多播小区测量参考信号和单小区测量参考信号分别设置一个门限的方式，不仅适用于第一测量事件中信号质量的计算，还可适用于S-mearsure的判决。
实施方式3.测量配置信息包括第一门限和/或第二门限。
一种可选的实施方式中，当测量配置信息包括第一门限和第二门限时，或者测量配置信息包括第一门限，或者测量配置信息包括第二门限时，终端设备根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，确定触发测量配置信息中的测量事件，包括：终端设备在多播小区测量参考信号的测量结果满足第二门限，或者单小区测量参考信号的测量结果满足第三门限时，确定触发第二门限和第三门限对应的第二测量事件。
其中，第二门限和第三门限的确定方式与上述权重系数的确定方式相同，不再赘述。第二测量事件也可参见上述描述，不再赘述。
可理解的，当测量配置信息包括第一门限和/或第二门限时，终端设备可在多播小区测量参考信号的测量结果或者单小区测量参考信号的测量结果满足对应的门限时，确定触发第二测量事件。
另外，多播小区测量参考信号的测量结果满足第二门限，以及单播小区测量参考信号的测量结果满足第三门限的含义也是根据第二测量事件确定的，不再赘述。
本申请实施例中，当终端设备确定触发第二测量事件时，终端设备将满足第二测量事件进入条件的多播小区和单小区加入到测量报告的CellsTriggeredList中。另外，终端设备在多播小区测量参考信号的测量结果不满足第二门限对应的门限，以及单小区测量参考信号的测量结果不满足第三门限对应的门限，且持续TimeToTriger时间时，即满足第二测量事件的离开条件时，将满足离开条件的多播小区和单小区从CellsTriggeredList删除。其中，第二门限对应的门限是根据第一门限和偏移量确定的，第三门限对应的门限是根据第三门限和偏移量确定的。
另一种可选的实施方式中，当测量配置信息包括第一门限和第二门限时，或者测量配置信息包括第一门限，或者测量配置信息包括第二门限时，终端设备根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，确定不触发测量配置信息中的测量事件，包括：终端设备在多播小区测量参考信号的测量结果满足第二门限，以及单小区测量参考信号的测量结果满足第三门限时，确定不触发第二门限和第三门限对应的第二测量事件。
可理解的，当测量配置信息包括第二门限和/或第三门限时，终端设备在多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果均不满足对应的门限，且持续TimeToTriger时间时，确定不触发第二测量事件。
例如，第二测量事件中涉及服务小区的测量，需要检测服务小区的信号质量是否高于一门限，与多播小区测量参考信号关联的第一门限为MeasTriggerQuantity1，与单小区测量参考信号关联的第二门限为MeasTriggerQuantity2，多播小区测量参考信号的测量结果为Ms1，单小区测量参考信号的测量结果为Ms2，多播小区测量参考信号对应的偏置为hysteresis1，单小区测量参考信号对应的偏置为hysteresis2。
那么，第二门限和第三门限对应的第二测量事件如下：当满足Ms1-hysteresis1〉MeasTriggerQuantity1，或者Ms2-hysteresis2〉MeasTriggerQuantity2，且持续TimeToTriger时，终端设备确定触发第二测量事件，将满足进入条件的多播小区和单小区添加到测量报告的CellsTriggeredList中；当满足Ms1-hysteresis1<MeasTriggerQuantity1-Hys1，以及满足Ms2-hysteresis2<MeasTriggerQuantity2-Hys2，且持续时间TimeToTriger时，终端设备确定符合第二测量事件的离开条件，将满足离开条件的多播小区和单小区从CellsTriggeredList中删除。其中，Hys1、Hys2为偏移量。
上述对多播小区测量参考信号和单小区测量参考信号分别设置一个门限的方式，不仅适用于第一测量事件中信号质量的计算，还可适用于S-mearsure的判决。
S103.终端设备在确定触发测量配置信息中的测量事件时，上报测量报告。
S104.网络设备接收测量报告。
这里，测量报告可以是基于多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果确定的。
一种可选的实施方式中，终端设备确定触发上述第一测量事件时，上报测量报告，该测量报告包括加权后的测量结果。也就是说，终端设备在确定触发第一测量事件时，根据加权后的测量结果，生成测量报告，并向网络设备上报该测量报告。一方面，终端设备根据加权 后的测量结果确定触发上述第一测量事件，使得终端设备触发第一测量事件更加准确；另一方面，该方法可使得终端设备在确定触发测量事件时，通过测量报告上报加权后的测量结果，可以减少网络设备根据传统的单小区测量参考信号的测量结果，确定终端设备是否需要进行小区切换所导致的移动性管理可靠性较低的问题，也就是说，可使得网络设备根据加权后的测量结果确定终端设备是否需要进行小区切换，使得网络设备确定终端设备是否需要进行小区切换更为准确，因此可实现更为可靠的移动性管理。
另一种可选的实施方式中，终端设备确定触发上述第二测量事件时，上报测量报告，该测量报告包括多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果。也就是说，不论终端设备是在多播小区测量参考信号的测量结果满足第二门限和单小区测量参考信号的测量结果满足第三门限，还是在多播小区测量参考信号的测量结果满足第二门限，或者单小区测量参考信号的测量结果满足第三门限时，确定触发第二测量事件的，终端设备可以根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果生成测量报告，并上报该测量报告。从而使得网络设备不是根据传统的单小区测量参考信号的测量结果确定终端设备是否需要进行小区切换，而是根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，联合确定终端设备是否需要进行小区切换，使得网络设备确定终端设备是否需要进行小区切换更为准确，从而可实现更为可靠的移动性管理。
一种可选的实施方式中，终端设备确定触发上述第一测量事件/第二测量事件时，上报测量报告，且终端设备上报测量报告的次数未达到测量配置信息中的上报次数时，根据测量配置信息中的上报间隔，继续上报该测量报告，直至上报测量报告的次数达到上报次数时，停止测量报告的上报。
另一种可选的实施方式中，测量配置信息中的上述reportAmount为infinity，那么终端设备确定触发上述第一测量事件/第二测量事件时，根据测量配置信息中的上报间隔，一直周期上报测量报告。
另外，一种可选的实施方式中，终端设备还可在上报测量报告时，启动定时器，并在定时器计时期间，停止测量报告的生成。也就是说，终端设备确定触发测量事件，上报测量报告期间，即使其他测量结果触发了对应的测量事件，终端设备也不再进行测量报告的生成，从而不进行其他测量报告的上报，以保证当前测量报告的成功上报。这里，停止测量报告的生成，也可以理解为跳过测量报告的生成。
本申请实施例还提供一种测量方法200。图6是该测量方法200的交互示意图。该测量方法200也是从终端设备和网络设备之间交互的角度进行阐述。该测量方法200包括但不限于以下步骤：
S201.终端设备根据测量配置信息，确定多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，测量配置信息包括多播小区测量参考信号和单小区测量参考信号的测量信息，以及上报周期。
S201的实施方式可参见上述S101的实施方式，不再赘述。
S202.终端设备根据上报周期，上报测量报告，测量报告是根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果生成的。
可理解的，测量配置信息中包括上报周期，那么网络设备给终端设备配置的是周期性上报测量报告，从而终端设备确定出多播小区测量参考信号的测量结果和单小区测量参考信号 的测量结果后，根据上报周期，周期性上报测量结果。该测量结果是根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果确定的。
其中，终端设备周期性上报测量报告的启动时刻，可以是被配置在测量配置信息的，也可以是网络设备和终端设备预先定义的，还可以是触发测量事件时的时刻。另外，上报周期是以报告间隔(reportInterval)的形式配置在测量配置信息中的。
一种可选的实施方式中，测量配置信息还包括一个或多个权重系数。那么终端设备根据上报周期，上报测量结果，包括：终端设备终端设备根据上述上报周期，上报测量报告，该测量报告包括加权后的测量结果，加权后的测量结果包括终端设备根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，以及一个或多个权重系数确定的测量结果。
其中，权重系数是根据以下一种或多种确定的：多播小区传输的业务的优先级、单小区传输的业务的优先级、多播小区传输的业务的服务质量标识符或单小区传输的业务的服务质量标识符。该实施方式和上述测量方法100中权重系数的实施方式相同，不再赘述。
也就是说，当测量配置信息中包括一个或多个权重系数时，终端设备是先根据一个或多个权重系数，以及多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，确定加权后的测量结果，然后根据上报周期上报测量报告，此时测量报告包括加权后的测量结果。
一种可能的实现方式中，测量报告包括measID，网络设备可根据measID，获知该测量报告对应的测量配置measconfig，进而根据该测量配置可获知终端设备上报的测量结果的类型。例如，测量报告中的measID对应的测量配置包括了加权系数，那么网络设备可知终端设备上报的测量结果为加权的测量结果。又例如，测量报告中的measID对应的测量配置包括了多个测量门限(上述第二门限和第三门限)，那么网络设备可知终端设备上报的测量结果为多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果。
另一种可能的实现方式中，测量报告还包括第二指示信息，第二指示信息用于指示当前上报的测量结果是加权的测量结果，还是多播小区测量参考信号的测量结果，还是单小区测量参考信号的测量结果。从而网络设备通过第二指示信息，或者当前接收到的测量结果的类型。
又一种可能的实现方式中，网络设备和终端设备预先定义可根据测量结果的数量确定测量结果的类型。例如，当终端设备当前上报的测量结果的数量为一个，则网络设备确定该测量结果是加权后的测量结果；当终端设备当前上报的测量结果的数量为两个时，则网络设备确定该测量结果是多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果；当终端设备当前上报的测量结果的数量为三个时，则网络设备确定该测量结果是多播小区测量参考信号的测量结果、单小区测量参考信号的测量结果，以及邻区测量参考信号的测量结果。
S203.网络设备接收测量报告。
本申请实施例中，终端设备根据测量配置信息，确定多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果后，根据上报周期，周期性上报测量报告，该测量报告是根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果确定的，从而使得网络设备不是根据单小区测量参考信号的测量结果确定终端设备是否需要进行小区切换，而是可根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，确定终端设备是否需要进行小区切换，进而有利于实现更为可靠的移动性管理。
本申请实施例中，上述测量方法100中的S104或测量方法200中的S203之后，网络设备和终端设备还可执行以下步骤：(1)网络设备根据测量报告，确定目标小区；(2)网络设备发送第一指示信息，第一指示信息用于指示目标小区；(3)终端设备接收第一指示信息；(4)终端设备向目标小区发起随机接入。
可理解的，网络设备接收到终端设备上报的测量报告后，根据测量报告中的测量结果，确定终端设备是否需要进行小区切换，且在确定终端设备需要进行小区切换时，确定终端设备需切换的目标小区。
一种可选的实施方式中，测量报告包括加权的测量结果，从而网络设备根据加权的测量结果确定目标小区。例如，加权后的测量结果小于邻区的信号质量，则网络设备确定当前服务小区的信号质量较差，终端设备需切换至邻区，因此确定邻区为目标小区。
另一种可选的实施方式中，测量报告包括多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，那么网络设备根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，确定终端设备需切换的目标小区。
本申请实施例中，网络设备根据测量报告中的测量结果，确定终端设备需切换的目标小区，并通过第一指示信息告知给终端设备，从而终端设备向目标小区发起随机接入，以实现小区的切换，完成移动性管理。终端设备切换的目标小区是根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果确定的，因此可实现更为可靠的移动性管理。
本申请实施例还提供一种测量方法300。图7是该测量方法300的流程示意图。该测量方法300是从终端设备的角度进行阐述。该测量方法300包括但不限于以下步骤：
S301.终端设备根据测量配置信息，确定多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，测量配置信息包括多播小区测量参考信号和单小区测量参考信号的测量信息。
S301的实施方式可参见上述S101的实施方式，不再赘述。
S302.终端设备在多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果满足切换条件时，根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果确定目标小区。
S303.终端设备向目标小区发起随机接入。
其中，切换条件是网络设备提前将切换命令下发给终端设备的，切换命令包括候选目标基站的无线参数配置、切换执行的触发条件，从而使得终端设备提前获知到如何接入目标基站。进而终端设备在候选目标基站中找到满足触发条件的基站后，可以自主决定发起切换执行。这样可增加消息成功传输的机会，可以提高切换的成功率。
本申请实施例中，终端设备需要具有条件切换(conditional handover，CHO)的能力。终端设备在初始接入、切换入或重建入小区时，会将其对同频CHO、异频CHO的支持能力通过UECapabilityInformation消息上报给gNodeB。
本申请实施例中，可以通过开关控制CHO。源小区的CHO功能开启后，源基站通过HANDOVER REQUEST消息与候选目标基站协商，协商可以进行CHO后(所有候选目标基站都需要给终端设备预留好资源)，源基站会将CHO的相关配置通过RRCReconfiguration(HO)消息下发给终端设备，从而终端设备开始进行CHO的信令流程。
以Xn切换为例，本申请的CHO切换与目前NR中的CHO切换的不同环节包括：切换准备、切换执行。
在切换准备的环节中，源基站将带有候选目标基站的天线参数配置和切换执行触发条件的而且换命令提前发送给终端设备，但终端设备不立即发起切换执行。此时，源基站下发测量控制的RRCReconfiguration消息给终端设备；源基站接收到终端设备的MeasurementReport后，源基站根据邻区关系向多个候选目标基站发送HANDOVER REQUEST，要求做条件切换；候选目标基站进行切换准入，若准入成功，候选目标基站反馈HANDOVER REQUEST ACKNOWLEDGE给源基站，准入成功后，所有的候选目标基站都会为终端设备预留好无线资源，直到收到源基站的切换取消消息；源基站发送CHO切换命令的RRCReconfiguration消息给终端设备，该消息包含了所有候选目标基站的无线空口配置和切换执行触发条件。
而在切换执行环节，终端设备找到满足切换执行触发条件的目标小区后，不需要再等待基站侧的切换命令，可以主动执行切换。
也就是说，终端设备在具备有CHO能力的条件下，可自行根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，以及CHO条件，确定自身是否需要从当前的服务小区切换至其他小区。
本申请实施例中，终端设备自行根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，确定需要切换的目标小区，并向目标小区发起随机接入，以自主完成移动性管理。其中，目标小区也是根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果确定的，因此可实现更为可靠的移动性管理。
另外，本申请实施例还提供一种如图8所示的测量的流程示意图。如图8所示，一种方式中，网络设备和终端设备执行上述测量方法100中的步骤，即源基站将测量配置信息下发给终端设备，终端设备根据该测量配置信息，测量多播小区测量参考信号和单小区测量参考信号，生成多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果。从而终端设备根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果，确定触发测量事件时，上报基于多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果生成的测量报告。进而网络设备根据测量报告中的测量结果，确定终端设备需切换的目标小区，并告知给终端设备，终端设备向目标小区的目标基站进行小区切换。
另一种方式中，网络设备和终端设备执行上述测量方法200中的步骤，即终端设备在确定出多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果后，直接根据测量配置信息中的上报周期，周期性上报根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果生成的测量报告，进而网络设备根据测量报告中的测量结果，确定终端设备需切换的目标小区，并告知给终端设备，终端设备向目标小区的目标基站进行小区切换。
又一种方式中，终端设备可执行上述测量方法300中的步骤，即终端设备自行根据多播小区测量参考信号的测量结果和单小区测量参考信号的测量结果和CHO的条件，确定是否需要进行小区切换。
为了实现上述本申请实施例提供的方法中的各功能，终端设备或网络设备可以包括硬件结构和/或软件模块，以硬件结构、软件模块、或硬件结构加软件模块的形式来实现上述各功能。上述各功能中的某个功能以硬件结构、软件模块、还是硬件结构加软件模块的方式来执行，取决于技术方案的特定应用和设计约束条件。
