Description

信息传递方法及装置 技术领域
本申请涉及通信技术领域，尤其涉及一种信息传递方法及装置。
背景技术
最小化路测(Minimization of Drive Test，MDT)是运营商通过签约用户的商用终端对网络覆盖的测量上报，实现自动收集终端测量数据的一种技术，以检测和优化无线网络中的问题和故障。
核心网设备会指定终端设备可以执行MDT时的公共陆地移动网络(Public Land Mobile Network，PLMN)列表，并告知接入网设备，接入网设备根据PLMN列表向终端设备配置MDT。当终端设备在某一接入网设备覆盖的小区内成功执行MDT测量后，可能会发生小区切换，比如终端设备切换至第一接入网设备覆盖的小区，如果该切换到的第一接入网设备覆盖的小区的PLMN不在上述PLMN列表内，终端设备无法执行MDT测量。如果终端设备从上述第一接入网设备覆盖的小区再次发生切换，例如切换至新的目标小区时，即使该新的目标小区的PLMN在上述PLMN列表内，该新的目标小区所关联的目标接入网设备仍无法获得上述PLMN列表，进而无法通知终端设备执行MDT。因此，终端设备进行小区切换导致PLMN列表在目标接入网设备侧丢失时，如何使得目标接入网设备获得PLMN列表是一个亟待解决的问题。

本申请实施例先对最小化路测(Minimization of Drive-Test，MDT)中的一些概念做下介绍。
1.MDT技术
3GPP RAN2工作组提出了最小化路测技术，是通信系统实现自动化采集和分析含位置信息的UE测量报告的技术，用于最大程度上减小人工路测的工作量。MDT的工作过程是核心网设备向接入网设备配置MDT，接入网设备再向终端设备配置MDT，终端设备执行MDT测量。
现有的MDT模式包括日志型的MDT(Logged MDT)和即时MDT(Immediate MDT)。Logged MDT主要针对处于空闲态(RRC_IDLE)的终端设备或RRC非激活态(RRC_INACTIVE)的终端设备进行的测量，主要测量包括终端设备对接收信号强度的测量。Immediate MDT主要针对处于连接态(RRC_CONNECTED)的终端设备进行的测量，主要测量包括终端的数据量、IP吞吐率、包传输时延、丢包率和处理时延等信息。
MDT的管理方式包括基于管理的MDT(management based MDT)和基于信令的MDT(signaling based MDT),基于管理的MDT是指核心网设备通知接入网设备进行MDT，接入网设备基于一定的策略从该接入网设备覆盖的终端中选择终端进行MDT测量。基于信令的MDT是核心网设备通知接入网设备选择某些特定终端进行MDT测量。
基于管理的MDT和基于信令的MDT是核心网设备对用户执行MDT时的管理方式，基于管理的MDT可以包括日志型的MDT和即时MDT，基于信令的MDT可以包括日志型的MDT和即时MDT。
当终端设备成功执行MDT时，核心网设备的统一数据管理(Unified Data Management,UDM)网元会保存终端设备执行MDT时的配置信息，该配置信息可以包含以下几种信息中的一种或多种：MDT模式，MDT的区域，MDT的管理模式及该模式下的配置参数，用户授权等。
当核心网设备通过接入网设备向终端配置MDT成功后，核心网设备的UDM可以存储终端设备执行MDT时的配置信息，并将存储的配置信息发送给移动性管理网元，由移动性管理网元发送给接入网设备。
2.PLMN列表
PLMN列表可以理解为允许终端设备执行MDT的PLMN的集合，该列表是由核心网设备指定的。终端设备发生小区切换时，如果切换后终端设备所在的小区的PLMN不在PLMN列表中，则终端设备在该小区内无法执行MDT。
3.用户授权(User Consent)
其中，用户授权也可以叫做用户同意信息，该用户授权用于表明终端是否允许激活MDT，用户授权的内容包含支持终端设备执行MDT测量时的PLMN列表。当终端设备所在的小区的PLMN在PLMN列表内，核心网设备向该小区对应的接入网设备发送MDT配置，该接入网设备向终端设备配置MDT。
4.跟踪区(Tracking Area，TA)
用来记录寻呼和位置更新的区域，在该区域中，终端设备不需要更新服务，通过TA可以实现对终端位置的管理，例如包括寻呼管理和位置更新管理。当终端设备处于空闲状态时，核心网设备能够知道终端设备所在的跟踪区，同时当处于空闲状态的终端设备需要被寻呼时，在终端设备所注册的跟踪区的所有小区进行寻呼。TA是小区级的配置，多个小区可以配置相同的TA，且一个小区只能属于一个TA。
5.跟踪区编码(Tracking Area Code，TAC)
每一个TA都会有自己的编号，编号分为两种，一种是跟踪区域码TAC，一种是跟踪区域标识(Tracking Area Identity,TAI)。其中TAC定义为运营商对Tracking Area的编号，TAI则是全球性的编号。TAI由移动国家码(Mobile Country Code，MCC)+移动网码(Mobile Network Code，MNC)+TAC组成。用户设备注册的跟踪区域的信息为跟踪区域标识TAI或跟踪区域编码码TAC。根据TAC可以确定MDT的区域范围(area scope)。
6.小区全球标识(Cell Global Identifier，CGI)
CGI可以用来识别一个小区所覆盖的区域，CGI由PLMN和小区标识组成，例如，在5G NR网络中，NCGI＝PLMN+NCI,其中NCGI表示NR CGI,NCI表示NR小区标识(NR Cell Identity)。核心网设备保存小区对应的CGI信息。可以理解的是，每个小区所属的PLMN 与CGI信息有对应关系，核心网设备可以根据CGI信息获知小区的PLMN。
7.服务PLMN
终端设备被配置MDT时，MDT的配置信息所绑定的PLMN信息，我们称之为服务PLMN(serving PLMN)。举例说明，终端设备在小区A时，小区A的PLMN信息为PLMN_a，PLMN_a在PLMN列表内，核心网设备通过小区A对应的接入网设备1向终端设备配置MDT，终端设备在小区A执行MDT，此时核心网设备的UDM保存MDT相关的配置信息，该配置信息包含PLMN列表，MDT的服务PLMN为PLMN_a。当终端设备从小区A切换至小区B，小区B的PLMN信息为PLMN_b，PLMN_b在PLMN列表内，终端设备继续执行MDT，此时MDT的服务PLMN仍为PLMN_a。当终端设备切换至小区C，小区C的PLMN信息为PLMN_c，PLMN_c在PLMN列表内，但核心网设备通过小区C对应的接入网设备2向终端设备更新MDT的配置，更新后的MDT相关的配置信息保存在核心网设备的UDM，此时，MDT的服务PLMN为PLMN_c。在所举例中，接入网设备2与接入网设备1可以是同一个接入网设备，也可以是不同的接入网设备。可以理解，终端设备在执行MDT时，发生小区切换，小区对应的PLMN信息发生变化，MDT的服务PLMN不一定发生变化。接入网设备向终端设备配置MDT时，会携带TA信息，该TA信息是从TA列表中根据服务PLMN索引得到的。接入网设备根据TA信息，确定终端设备执行MDT时的区域范围。
8.用户感知体验(Quality of Experience，QoE)测量
用户感知体验测量是对于一些流类业务或者语音业务而言，运营商收集用户的感知体验测量量，从而更好的优化网络。QoE测量也可称为应用层测量，接入网设备从核心网设备收到这些测量的配置信息，接入网设备把这些配置通过RRC消息发送给终端设备，终端设备的RRC层收到应用层的测量结果之后，把这些测量结果发送给接入网设备。
QoE测量的管理方式也包含基于信令的QoE测量和基于管理的QoE测量。QoE测量的测量指标包括-平均吞吐量、初始播放时延、缓冲级别、播放时延、恶化持续时间、连续的丢包数、抖动持续时间、往返时延、平均码率和卡顿情况等。
QoE测量与MDT类似，终端设备执行QoE测量时，终端设备所在的小区的PLMN需要在PLMN列表内，终端设备才能执行QoE测量。
在实际场景中，核心网设备通过接入网设备向终端设备配置MDT后，在一定的场景下，如果终端设备发生小区切换，终端设备在切换后的小区内仍可以执行MDT。例如，小区A对应接入网设备1，小区B对应接入网设备2，终端设备从小区A切换至小区B时，如果小区A的PLMN信息为PLMN_a，小区B的PLMN信息为PLMN_b，如果PLMN_a属于PLMN列表，PLMN_b属于PLMN列表，此时接入网设备1可以通过用户上下文信令向接入网设备2发送MDT相关的配置信息。进而接入网设备2可以向位于小区B内的终端设备配置MDT。
但当PLMN_a属于PLMN列表，PLMN_b不属于PLMN列表，切换至小区B后,接入网设备1无法通过用户上下文信令向接入网设备2发送MDT相关的配置信息。因此终端在该小区B内无法执行MDT。进而当终端设备切换至小区C，小区C的PLMN信息为PLMN_c,PLMN_c属于PLMN列表时，小区C对应的接入网设备可能仍无法获得 MDT相关的配置信息。
因此，本申请提出的一种信息传递的方法，当终端设备发生小区切换时，可以使得切换后终端设备所在的小区对应的接入网设备可以及时获得终端执行第一操作时的配置信息，避免因切换过程中接入网设备无法获得第一操作的配置信息而导致终端设备无法执行第一操作。可以理解的是，本申请实施例中，将MDT称为第一操作，该第一操作例如还可以是QoE测量。
在本申请实施例中，以MDT场景为例，对本申请中的一种信息传递的方法进行示意说明，可以理解，当本申请实施例中的MDT替换成QoE测量时，本申请实施例所说明的一种信息传递方法仍可以执行。
本申请提供的实施例适用于多种不同的场景。
图3A示出了本申请实施例可以适用的一种场景示意图。在该应用场景中，无线接入网络中至少包含两个接入网设备：第二接入网设备和第一接入网设备。终端设备从第二接入网设备覆盖的第二小区移动到第一接入网设备覆盖的第一小区，其中第二小区的第二PLMN与第一小区的第一PLMN不同。
图3B示出了本申请实施例可以使用的另一种场景示意图，在该应用场景中，无线接入网络中至少包含两个接入网设备：第二接入网设备和第一接入网设备。终端设备从第二接入网设备覆盖的第三小区移动到第一接入网设备覆盖的第二小区，进一步地，终端设备从第二小区切换至第一小区。其中第二小区和第一小区都对应第一接入网设备，第二小区对应的第二PLMN与第一小区对应的第一PLMN不同。
下面以具体实施例结合附图对本申请的技术方案进行详细说明。下述实施例和实施方式可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。应理解，本申请中所解释的功能可以通过独立硬件电路、使用结合处理器/微处理器或通用计算机而运行的软件、使用专用集成电路，和/或使用一个或多个数字信号处理器来实现。当本申请描述为方法时，其还可以在计算机处理器和被耦合到处理器的存储器中实现。
本申请实施例中，对MDT的模式或者MDT的管理方式不做限制，前述任一模式的MDT或任一管理方式下的任一模式的MDT均适用本申请实施例。除MDT外，其他面临PLMN列表在切换过程中丢失的场景，本申请实施例所说明的信息传递方法均适用。例如QoE测量时，如果PLMN列表在切换过程中丢失，采用本申请实施例所说明的信息传递方法，也可以保证小区切换过程中QoE测量的连续性。
本申请实施例中，终端设备在某接入网设备覆盖的小区内已成功执行MDT，此时，核心网设备的统一数据管理(Unified Data Management,UDM)会保存终端设备执行MDT时的第一信息，该第一信息中包含PLMN列表，该PLMN列表指示支持终端设备执行MDT的可用PLMN的集合。
在一种可能的实施方式中，该第一信息可以是用户授权(User Consent)，该用户授权中携带了上述PLMN列表。
在另一种可能的实施方式中，该第一信息中除了携带PLMN列表，还可以包含以下信息中的一种或多种：MDT模式，MDT的区域，MDT的管理模式及该模式下的配置参数。
关于MDT模式，MDT的区域，MDT的管理模式及该模式下的配置参数可以参考 3GPP TS32.422和3GPP TS37.320中相应概念的定义和说明。本申请实施例中不做赘述。可以理解，对上述概念的解释，不限于现有协议中的定义和说明。
在另一种可能的实施方式中，当MDT为基于信令的MDT时，该第一信息中还可以包含服务PLMN信息。
可选的，核心网设备的移动性管理网元可以从UDM中直接获得该第一信息，进而获的上述PLMN列表信息。
本申请实施例中，终端设备在某小区内被成功配置MDT，该小区被称之为起始服务小区，起始服务小区的PLMN信息即是MDT的服务PLMN信息。可以理解的是，起始服务小区并不一定是终端设备初始接入网络时的小区，仅用于表述终端设备被配置MDT时终端设备当前所在的小区，该小区的PLMN即为服务PLMN。基于前述对服务PLMN的解释，可以理解，当终端设备从起始服务小区切换至新的小区时，新的小区的PLMN属于PLMN列表，即新的小区的PLMN在PLMN列表内，终端设备仍继续执行MDT，如果核心网设备未更新MDT的配置信息，终端设备在新的小区内执行MDT时的服务PLMN仍是起始服务小区的PLMN。如果终端设备在新的小区内，新的小区对应的接入网设备接收到核心网设备触发更新MDT配置，接入网设备更新MDT配置后，向终端设备配置MDT，终端设备在新的小区内执行MDT时的服务PLMN更新为新的小区的PLMN。进一步地，可以理解，核心网设备更新MDT配置后，终端设备执行MDT的起始服务小区更新为新的小区，服务PLMN更新为新的小区的PLMN。
在本申请实施例中，终端设备被配置MDT后，终端设备在第三小区成功执行MDT，终端设备从第三小区切换至第二小区，第二小区的PLMN信息称之为第二PLMN信息，第二PLMN信息不属于PLMN列表，则终端无法在第二小区内执行MDT。终端设备从第二小区切换至第一小区，第一小区的PLMN信息称之为第一PLMN信息，如果第一PLMN信息属于PLMN列表，为了使得终端设备能够在第一小区内继续执行MDT，本申请实施例提出了一种信息传递的方法，如图4所示，图4为该信息传递方法400的交互示意图。图4中以第二小区对应的接入网设备、第一小区对应的接入网设备和核心网设备作为该交互示意的执行主体为例来示意该信息传递方法，但本申请并不限制该交互示意的执行主体。例如，图4中的接入网设备也可以是支持该接入网设备实现该方法的芯片、芯片系统、或处理器，图4中的核心网设备也可以是支持该核心网设备实现该方法的芯片、芯片系统、或处理器，或者是该核心网设备中支持实现该方法的功能网元。
图4中示意的方法400包括410部分至430部分。通过该方法，当终端设备发生小区切换时，切换后终端设备所在的第一小区对应的第一接入网设备可以获得终端执行第一操作时的第一信息，避免因切换过程中第一接入网设备无法获得第一操作的第一信息而导致终端设备无法执行第一操作，保证终端执行第一操作的连续性。下面以第一操作为MDT为例，对本申请实施例提供的方法400进行介绍。
410：核心网设备获知第一小区的第一公共陆地移动网络PLMN信息。
例如，终端设备在第三小区发生小区切换(从第三小区切换至第二小区)，核心网设备获知第二小区对应的第二PLMN信息，其中，该第三小区是终端设备成功执行过MDT的小区。之后，终端设备从第二小区切换至第一小区，核心网设备获知第一小区对应的第一PLMN信息，该第一小区是终端设备从第二小区切换后的第一个小区，即第二小区是 终端设备最近一次切换至第一小区前所在的小区。
可选地，终端设备在第三小区成功执行MDT，终端设备从第三小区切换至第二小区时，第三小区对应的第三接入网设备可以向第二小区对应的第二接入网设备通知终端设备成功配置过MDT，终端设备从第二小区切换至第一小区时，第二接入网设备向第一小区对应的第一接入网设备通知终端设备成功配置过MDT。通过该方法，第一接入网设备可以获知终端设备需要执行MDT，进而第一接入网设备确定需要接收来自核心网设备的MDT的配置信息。本申请实施例对不同接入网设备之间通知终端设备成功配置过MDT的方式不做限制，例如，第二接入网设备可以通过切换请求中携带上述信息，相应的，第一接入网设备接收该切换请求后，获得切换请求中携带的上述信息。
在一种可能的实施方式中，终端设备切换至第二小区，第二接入网设备向核心网设备上报第二小区对应的第二PLMN信息，核心网获知该第二PLMN信息。终端设备从第二小区切换至第一小区，第一接入网设备向核心网设备上报第一小区对应的第一PLMN信息，核心网获知该第一PLMN信息。可以理解，第一接入网设备和第二接入网设备连接的核心网设备可以是相同的，也可以是不同的。
在本申请实施例中，接入网设备获知终端设备所在的小区对应的PLMN信息的方式不受限制。
在一种可能的实施方式中，接入网设备可以向核心网设备上报对应小区的PLMN信息。本申请实施例对接入网设备上报小区对应的PLMN信息的方式不做限制。以第二接入网设备向核心网设备上报第二小区对应的第二PLMN的方式进行说明。例如，第二接入网设备可以采用专门的信令向核心网设备上报第二PLMN信息，或者第二接入网设备采用在已有的信令中携带第二PLMN信息的方式向核心网设备上报第二PLMN信息。例如，该已有的信令例如可以是路径切换请求(path switch req)。可选的，第一接入网设备可以采用类似的方式向核心网设备上报第一小区对应的PLMN信息。
在另一种可能的实施方式中，终端设备切换至第二小区，核心网设备收到第二小区的全球标识CGI，核心网设备根据该该CGI确定第二小区对应的第二PLMN信息。可选的，在终端设备从第二小区切换至第一小区的情况下，类似的，核心网设备可以根据第一小区的CGI确定第一小区对应的第一PLMN信息。
可以理解的是，核心网设备获知上述第一PLMN信息和第二PLMN信息的方式可能不同，例如，第一PLMN信息是第一接入网设备上报给核心网设备的，第二PLMN是核心网设备根据第二小区的CGI确定的。又例如，第一PLMN信息是核心网设备根据第一小区的CGI确定的，第二PLMN信息是第二接入网设备上报给核心网设备的。可以理解的是，核心网设备获知小区的PLMN信息的方式在本申请中不做限制。
420：核心网设备根据第一PLMN信息确定向第一接入网设备发送第一信息。
一种可能的实现方式中，核心网设备根据上述第二PLMN信息和上述第一PLMN信息确定是否向第一接入网设备发送第一信息。例如，当核心网设备确定第二PLMN不属于PLMN列表，第一PLMN属于PLMN列表时，核心网设备确定向第一接入网设备发送第一信息，执行430。该第一信息中包含PLMN列表，该PLMN列表包含允许终端设备执行MDT的PLMN集合。又例如，当核心网设备确定第二PLMN不属于PLMN列表，第一PLMN也不属于PLMN列表时，核心网设备确定不向第一接入网设备发送 第一信息。
在一种可能的实施方式中，上述第一信息中包含用户授权(User Consent)，该用户授权中携带了上述PLMN列表。
在一种可能的实施方式中，该第一信息还包含服务PLMN信息。
430：核心网设备向第一接入网设备发送第一信息。
在一种可能的实施方式中，核心网设备的移动性管理网元向第一接入网设备发送该第一信息。
相应的，第一接入网设备接收来自核心网设备的第一信息，进而可以向终端设备配置MDT，保证了终端设备执行MDT测量的连续性。
在本申请实施例中，核心网设备向第一接入网设备发送该第一信息的方式不受限制。例如，核心网设备可以采用专门的信令直接向第一接入网设备发送该第一信息；或者核心网设备采用在已有的信令中携带第一信息的方式向接入网设备发送该第一信息，例如，该已有的信令例如可以是路径切换请求响应(Path Switch Req Ack)。
在一种可能的实施方式中，核心网发送的第一信息中还可以包含服务PLMN信息。那么，第一接入网设备可以根据接收到的服务PLMN信息获得跟踪区域码块列表，避免因为PLMN变化导致跟踪区域码块列表索引错误。
在本申请实施例中，基于前述步骤的描述，终端设备执行MDT时发生小区切换，当终端设备从第二小区切换至第一小区时，第一小区对应的第一接入网设备可以通过核心网设备重新获取该终端设备执行MDT的第一信息，可以向终端设备配置MDT，保证了终端设备执行MDT的连续性。
在本申请实施例中，第三小区对应的第三接入网设备、第二小区对应的第二接入网设备和第一小区对应的第一接入网设备可以是同一接入网设备，也可以是不同的接入网设备。
例如，当第三接入网设备、第二接入设备和第一接入网设备均不相同时，因为第二小区的第二PLMN不属于PLMN列表，第三接入网设备无法通过用户上下文信令向第二接入网设备发送第一信息，当终端设备从第二小区切换至第一小区时，第一接入网设备可以通过上述信息传递方法400，获得第一信息，保证终端设备在第一小区内继续执行MDT。
又例如，当第二接入网设备与第一接入网设备相同，记为第一接入网设备，第一接入网设备与第三接入网设备不相同时，终端设备从第三小区切换至第二小区，因为第二PLMN不属于PLMN列表，第三接入网设备无法通过用户上下文信令向第一接入网设备发送第一信息。当终端设备从第二小区切换至第一小区时，第一接入网设备可以通过上述信息传递方法400，获得第一信息，保证终端设备在第一小区内继续执行MDT。
又例如，当第三接入网设备与第二接入设备相同，记为第三接入网设备，第一接入网设备与第三接入网设备不相同时，终端设备从第三小区切换至第二小区，因为第二PLMN不属于PLMN列表，终端设备在第二小区无法执行MDT,当终端设备从第二小区切换至第一小区时，第一接入网设备可以通过上述信息传递方法400，获得第一信息，保证终端设备在第一小区内继续执行MDT。
又例如，当第三接入网设备、第二接入设备和第一接入网设备均相同时，记为第一 接入网设备，即第三小区、第二小区和第一小区均对应于第一接入网设备，通过上述信息传递方法400，第一接入网设备可以获得核心网设备配置的第一信息，向终端设备配置MDT。在另一种可能的实施方式中，终端设备进行了小区切换，而第一接入网设备保持不变，第一接入网设备可以直接向位于第一小区内的终端设备配置MDT。
图5为本申请实施例提供的另一种信息传递方法500的交互示意图。以第二接入网设备、第一接入网设备和核心网设备作为该交互示意的执行主体为例来示意该信息传递方法，但本申请并不限制该交互示意的执行主体。例如，图5中的接入网设备也可以是支持该接入网设备实现该方法的芯片、芯片系统、或处理器，图5中的核心网设备也可以是支持该核心网设备实现该方法的芯片、芯片系统、或处理器，或者是该核心网设备中支持实现该方法的功能网元。
图5中示意的方法500包括510部分至530部分。通过该方法，当终端设备发生小区切换时，切换后终端设备所在的第一小区对应的第一接入网设备可以获得终端执行第一操作时的第一信息，避免因切换过程中第一接入网设备无法获得第一信息而导致终端设备无法执行第一操作，保证终端执行第一操作的连续性。下面以第一操作为MDT为例，对本申请实施例提供的方法500进行介绍。
510a：核心网设备获知第一小区的第一PLMN信息。
在本申请实施例中，接入网设备获知终端设备所在的第一小区的第一PLMN信息的方式不受限制，可以参考前述信息传递方法400中在410部分的对应描述，此处不再赘述。
510b：核心网设备从第一接入网设备接收第一请求。
终端设备切换至第一小区时，第一小区对应的第一接入网设备向核心网设备发送第一请求，该第一请求指示第一接入网设备向核心网设备请求终端设备执行MDT时的第一信息。相应地，核心网设备接收该第一请求。
可以理解，本申请实施例并不限定第一请求的具体名称，第一请求仅仅是一种可能名称，第一请求用于指示第一接入网设备向核心网设备请求终端设备执行MDT时的第一信息，其他任何能够实现上述功能的信息都应被理解为本申请方案中的第一请求。
对第一信息的内容描述，可以参考前述信息传输方法400中在420部分的对应描述，此处不再赘述。
第一接入网设备向核心网设备发送第一请求可以是无条件的，也可以是有条件的。对于有条件的发送第一请求例如可以是在第一接入网设备获知切换前后所属的小区的PLMN不同(或者说PLMN信息发生变化)的情况下再发送该第一请求。
一种可能的实现方式中，第一接入网设备可以是在终端设备指示第一PLMN信息和第二PLMN信息不同的情况下，向核心网设备发送第一请求。例如，终端设备在第二小区时，获知第二小区的第二PLMN信息，当终端设备从第二小区切换至第一小区时，终端设备获得第一小区的第一PLMN信息，如果终端设备判断第一PLMN信息与第二PLMN信息不同，终端设备向第一接入网设备指示第一PLMN信息和第二PLMN不同(即发送第一指示)。第一接入网设备接收到该第一指示，向核心网设备发送上述第一请求。相应地，核心网设备接收该第一情求。
可以理解，该第一指示用于指示终端设备发生小区切换时，切换前后所属小区的 PLMN信息不同，本申请实施例并不限定第一指示的具体名称，第一指示仅仅是一种可能名称，其他的名称例如，第一指示可以被称为PLMN变化指示，或者其他任何能够实现上述功能的信息都应被理解为本申请方案中的第一指示。
在另一种可能的实施方式中，可以是第一接入网设备根据切换前后所属的小区的PLMN信息判断PLMN信息是否发生变化，从而在第一接入网设备确定PLMN信息发生变化的情况下，向核心网设备发送第一请求。例如，终端设备从第二小区切换至第一小区时，第二小区对应的第二接入网设备向第一小区对应的第一接入网设备发送第二PLMN信息，第一接入网设备接收该第二PLMN信息，当第一接入网设备判断出该第二PLMN信息与第一PLMN信息不同时，第一接入网设备向核心网设备发送上述第一请求。相应地，核心网设备接收该第一请求。
在一种可能的实施方式中，第一请求可以携带于第一接入网设备向核心网设备发送的已有的信令中，例如，该已有的信令例如可以是路径切换请求。相应地，接入网设备接收到路径切换请求信令，获知该第一请求。
可以理解，本申请实施例中510a和510b步骤的执行可以不限定顺序，例如，510a在前，510b在后，或者510b在前，510a在后。需要说明的是，510a和510b未在图中示出。
在另一种可能的实施方式中，510a和510b可以合并执行，为510步骤，即：
510：核心网设备从第一接入网设备接收第一请求，该第一请求中包括第一小区的第一PLMN信息。
第一接入网设备发送第一请求时，第一请求携带第一小区的第一PLMN信息。相应地，接入网设备接收到该第一请求时，获知该第一PLMN信息。第一PLMN信息携带于第一请求中时，所述方法有利于减少第一接入网设备与核心网设备之间的信令开销。
520：核心网设备根据第一PLMN信息确定向第一接入网设备发送第一信息。
当核心网设备确定第一PLMN信息属于PLMN列表时，该核心网设备确定向第一接入网设备发送上述第一信息。
在一种可能的实施例中，当核心网设备确定第一PLMN信息不属于PLMN列表时，该核心网设备确定不向第一接入网设备发送第一信息。
530：核心网设备向第一接入网设备发送第一信息。
具体地，步骤530可以参考前述信息传输方法400中在步骤430的对应描述，此处不再赘述。
在本申请实施例中，基于前述步骤的描述，终端设备发生小区切换时，第一接入网设备可以通过向核心网发送第一请求信息，重新获取该终端设备执行MDT的第一信息，第一接入网设备可以向终端设备重新配置MDT，保证了终端设备执行MDT的连续性。
图6为本申请实施例提供的另一种信息传递方法600的交互示意图，以终端设备、第一接入网设备和核心网设备作为该交互示意的执行主体为例来示意该信息传递方法，但本申请并不限制该交互示意的执行主体。例如，图6中的终端也可以是支持该终端实现该方法的芯片、芯片系统、或处理器。图6中的接入网设备也可以是支持该接入网设备实现该方法的芯片、芯片系统、或处理器。图6中的核心网设备也可以是支持该核心网设备实现该方法的芯片、芯片系统、或处理器，或者是该核心网设备中支持实现该方 法的功能网元。
图6中示意的方法600包括610部分至640部分。通过该方法，当终端发生小区切换时，第一接入网设备从终端设备获得终端设备执行第一操作时的第一信息，避免因切换过程中第一接入网设备无法获得该第一信息而导致终端设备无法执行第一操作，保证终端执行MDT的连续性。下面以第一操作为MDT为例，对本申请实施例提供的方法600进行介绍。
610：终端设备接收并存储第一信息。
终端设备在某小区成功执行MDT，此时终端设备存储第一信息，该第一信息包含终端设备执行MDT的配置信息。第一信息的定义和内容，可以参考前述实施例中步骤410对第一信息的解释，这里不再赘述。
可以理解，该第一信息的传递方式在本申请实施例中不做限制，例如，该第一信息通过无线资源控制信令的格式发送，或者该第一信息通过多媒体接入控制层的控制单元信令的格式发送，或者该第一信息通过其他可以实现信令传输的方式发送。
可选地，当终端设备执行MDT时，核心网设备可以更新MDT的配置信息，记为第二信息，终端设备会接收并存储该第二信息，可以理解，终端设备存储的第一信息更新为第二信息，为了便于理解和描述，该第二信息仍记为第一信息。
620：终端设备获知第一小区的PLMN信息。
例如，终端设备发生小区切换，切换至第一小区，终端设备接收来自第一接入网设备对应的第一小区的第一PLMN信息。
630：终端设备根据第一PLMN确定向第一接入网设备发送第一信息。
如果终端设备根据接收到的第一PLMN信息确定第一PLMN在PLMN列表内，终端设备确定向第一小区对应的第一接入网设备发送第一信息。
在一种可能的实施例中，如果终端设备确定第一PLMN不属于PLMN列表时，该终端设备确定不向第一接入网设备发送第一信息。
640：终端设备向第一接入网设备发送第一信息。
在本申请实施例中，基于前述步骤的描述，终端设备发生网络切换时，第一接入网设备可以通过终端设备重新获取该终端设备执行MDT的第一信息，减少第一接入网设备与核心网设备之间的信令交互，保证了终端设备执行MDT的连续性。在MDT测量中，如何计算分裂承载(split Bearer)下的吞吐量也是一个亟需解决的问题。
本申请实施例提供了一种确定吞吐量的方法，用于实现在分裂承载下场景下的吞吐量计算。
本申请实施例先对分裂承载(split Bearer)场景下的一些概念做下介绍。
1.双连接(Dual-Connectivity,DC)
双连接是3GPP Release-12版本引入的重要技术。通过双连接技术，LTE宏站和小站可以利用现有的非理想回传(non-ideal backhaul)X2接口来实现载波聚合，从而为用户提供更高的速率，以及利用宏/微组网提高频谱效率和负载平衡。支持双连接的终端设备可以同时连接两个LTE基站，增加单用户的吞吐量。
3GPP Release-14在LTE双连接技术基础上，定义了LTE和5G的双连接技术。LTE/5G双连接是运营商实现LTE和5G融合组网、灵活部署场景的关键技术。在5G 早期可以基于现有的LTE核心网实现快速部署，后期可以通过LTE和5G的联合组网来实现全面的网络覆盖，提高整个网络系统的无线资源利用率、降低系统切换时延以及提高用户和系统性能。
LTE/5G，5G/5G双连接模式有多种组合，如图7所示，包括：
1)核心网为EPC时，LTE基站做主站，NR基站做辅站，如图7中的A所示。此时LTE基站和NR基站之间存在X2接口，至少有控制面连接，可以还有用户面连接；LTE基站和EPC之间存在S1接口，至少有控制面连接，可以还有用户面连接；NR基站和EPC之间存在S1-U接口，即只可以有用户面连接。此时LTE基站可以通过至少一个LTE小区为用户提供空口资源，此时所述至少一个LTE小区称为主小区组(Master Cell Group,MCG)。相应的，NR基站也可以通过至少一个NR小区为用户提供空口资源，此时所述至少一个NR小区称为辅小区组(Secondary Cell Group,SCG)。
2)核心网为5GC时，LTE基站做主站，NR基站做辅站，如图7中的B所示。此时LTE基站和NR基站之间存在Xn接口，至少有控制面连接，可以还有用户面连接；LTE基站和5GC之间存在NG接口，至少有控制面连接，可以还有用户面连接；NR基站和5GC之间存在NG-U接口，即只可以有用户面连接。此时LTE基站可以通过至少一个LTE小区为用户提供空口资源，此时所述至少一个LTE小区称为MCG。相应的，NR基站也可以通过至少一个NR小区为用户提供空口资源，此时所述至少一个NR小区称为SCG。
3)核心网为5GC时，NR基站做主站，LTE基站做辅站，如图7中的C所示。此时NR基站和LTE基站之间存在Xn接口，至少有控制面连接，可以还有用户面连接；NR基站和5GC之间存在NG接口，至少有控制面连接，可以还有用户面连接；NR基站和5GC之间存在NG-U接口，即只可以有用户面连接。此时NR基站可以通过至少一个NR小区为用户提供空口资源，此时所述至少一个NR小区称为MCG。相应的，LTE基站也可以通过至少一个LTE小区为用户提供空口资源，此时所述至少一个LTE小区称为SCG。
4)核心网为5GC时，主辅站都是NR基站,如图7中的D所示。主辅站之间的接口为Xn接口，至少有控制面连接，可以还有用户面连接；NR主基站和5GC之间存在NG接口，至少有控制面连接，可以还有用户面连接；NR辅基站和5GC之间存在NG-U接口，即只可以有用户面连接。此时NR主基站可以通过至少一个NR小区为用户提供空口资源，此时所述至少一个NR小区称为MCG。相应的，NR辅基站也可以通过至少一个NR小区为用户提供空口资源，此时所述至少一个NR小区称为SCG。
2.主节点(master node，MN)
在MR-DC中，控制面与核心网相连的节点。
3.辅节点(Secondary node，SN)
在MR-DC中，没有控制面与核心网相连的节点，但可以给UE提供额外的辅助无线资源的无线接入节点。
4.主小区组(Master Cell Group,MCG)
跟主节点(Master node,MN)相关联的一组服务小区，由SpCell(Pcell)和可能存在的一个或多个Scell组成。Pcell即为主小区(Primary cell)，是MCG里面所有小区的老 大，是用户在MCG里面连接的第一个小区，而Scell即为辅小区(Secondary cell)，是主小区组里面除了PCell以外的小区。
5.辅小区组(Secondary Cell Group,SCG)
跟辅节点(Secondary node，SN)相关联的一组服务小区，由SpCell(PSCell)和可能存在的一个或多个Scell组成。PSCell即为主辅小区，是SCG里面所有小区的老大，是用户在SCG里面连接的第一个小区。SCG里面除了PSCell以外的小区也叫做SCell。
6.双连接的承载
MN承载的数据单元可以通过MN空口资源和/或SN空口资源发送，SN承载的数据单元可以通过MN空口资源和/或SN空口资源发送。当仅通过MN空口资源发送数据单元时，称为通过MCG承载发送数据单元。当仅通过SN空口资源发送数据单元时，称为通过SCG承载发送数据单元。既通过MN空口资源发送数据单元也通过SN空口资源发送数据单元时，称为通过分裂承载发送数据单元，分裂承载包括MCG分裂承载和SCG分裂承载。
MCG bearer：MR-DC中，RLC承载仅存在于MCG中的无线承载RB；
SCG bearer：MR-DC中，RLC承载仅存在于SCG中的无线承载RB；
Split bearer：MR-DC中，RLC承载存在于MCG和SCG中的无线承载RB；split bearer的锚点节点可以理解为split bearer的PDCP实体所在的的节点。
MN Terminated bearer：MR-DC中，PDCP实体存在于MN中的无线承载RB；
SN Terminated bearer：MR-DC中，PDCP实体存在于SN中的无线承载RB；
7.锚点
双链接中，锚点指信令接入的节点。例如在EN-DC非独立组网中，锚点在LTE基站，锚点连LTE核心网，信令走LTE。NE-DC非独立组网中，锚点在NR基站，锚点连NR核心网，信令走NR。
图8为本申请实施例提供的一种确定吞吐量的方法800的交互示意图。以终端设备、第一节点和第二节点作为该交互示意的执行主体为例来示意该方法，但本申请并不限制该交互示意的执行主体。例如，图8中的终端设备也可以是支持该终端设备实现该方法的芯片、芯片系统、或处理器。图8中的第一节点或第二节点也可以是支持该第一节点或第二节点实现该方法的芯片、芯片系统、或处理器。可以理解的是，第一节点和第二节点是MR-DC场景中的接入网设备。
图8中示意的方法800包括810至840。通过该方法，可以获得分裂承载的吞吐量。
810：第一节点向第二节点发送吞吐量测量的配置信息。
相应的，第二节点接收该配置信息。
其中，第一节点可以是主节点，第二节点是辅节点，或者第一节点是辅节点，第二节点是主节点。
该配置信息包含测量周期长度。该测量周期指示终端设备与第一节点之间或者终端设备与第二节点之间执行吞吐量测量的时间长度。
在一种可能的实施方式中，该配置信息中包含终端设备与第一节点之间或者终端设备与第二节点之间执行吞吐量测量的起始时间信息和截止时间信息，根据起始时间信息和截止时间信息，也可以获得终端设备与第一节点之间或者终端设备与第二节点之间执 行吞吐量测量的时间长度。
在另一种可能的实施方式中，该配置信息中包括上述测量周期长度和时间节点，该时间节点可以是上述起始时间信息、截止时间信息中的一种。例如，根据周期长度和起始时间信息，可以获得吞吐量测量的截止时间，或者根据周期长度和截止时间信息，可以获得吞吐量测量的起始时间。
在另一种可能的实施方式中，该配置信息包括测量周期、吞吐量测量的起始时间信息和截止时间信息。
根据配置信息，第一节点或第二节点可以周期性的执行吞吐量测量。如图9所示。
在一种可能的实施方式中，配置信息中包含至少两个测量周期，该至少两个测量周期中的时域长度不同，第一节点或第二节点可以基于该至少两个测量周期，在每个测量周期内执行吞吐量测量。通过该方法，第一节点或第二节点可以灵活执行吞吐量测量，保证吞吐量测量过程的多样性。
820：第一节点和第二节点进行吞吐量测量。
例如，第一节点统计第一节点与终端设备之间的吞吐量测量值，第二节点统计第二节点与终端设备之间的吞吐量测量值。
在一种可能的实施方式中，在一个测量周期内，第一节点、第二节点分别与终端设备之间的吞吐量测量可以是对在测量周期内的多个时间段内的吞吐量测量统计。如图9所示。
图9为本申请实施例中第一节点、第二节点分别与终端设备之间的吞吐量测量的方法。具体地，在一个测量周期内，假设第一节点与终端设备进行了m次传输，在m次传输中的数据量分别为X 11,X 12,…X 1m，在m次传输中的传输时间分别为T 11,T 12,…T 1m，记为第一节点吞吐量统计信息。第二节点与终端设备在测量周期内进行了n次传输，在n次传输中的数据量分别为X 21,X 22,…X 2n，在n次传输中的传输时间分别为T 21,T 22,…T 2n，记为第二节点吞吐量统计信息。其中，m与n为大于等于1的整数，m与n的取值可以相同，也可以不同。吞吐量统计信息可以包括测量周期内的数据量信息，或者包括测量周期内的数据量信息和有效传输时间信息。可以理解，第一节点吞吐量统计信息和第二节点吞吐量统计信息仅仅是一种表述的名称，并未限定上述执行步骤，在本申请实施例中不做限制，其他任何可以表述上述吞吐量统计信息的名称均适用。
可选的，第一节点、第二节点分别与终端设备之间的吞吐量测量过程中，m次传输中每次传输的起始时刻和结束时刻，与n次传输中每次传输的起始时刻和结束时刻可以对其，也可以不对齐。m次传输中每段传输时长与n次传输中每段传输时长可以相同，也可以不同。通过该方法，保证列第一节点、第二节点分别于终端设备之间的吞吐量测量的灵活性。
830：计算每个测量周期内的分裂承载吞吐量。
一种可能的实现方式中，第一节点接收来自第二节点的吞吐量统计信息，根据第一节点吞吐量统计信息和第二节点吞吐量统计信息，计算每个周期内的分裂承载吞吐量。
在另一种可能的实施方式中，第一节点将第一节点吞吐量统计信息和第二节点吞吐量统计信息发送给核心网设备，核心网设备计算每个周期内的分裂承载吞吐量。
在另一种可能的实施方式中，核心网设备接收来自第一节点的第一节点吞吐量统计 信息和来自第二节点的第二节点吞吐量统计信息，然后计算每个周期内的分裂承载吞吐量。
分裂承载吞吐量计算方法为：
X split_bearer＝(X 11+X 12+…+X 1m+X 21+X 22+…+X 2n)/T all       (1)
其中，T all是根据T 11,T 12,…T 1m和T 21,T 22,…T 2n确定的，T all的计算方式为以下几种方式中的其中一种：
T all＝max(T 11+T 12+…+T 1m，T 21+T 22+…+T 2n)      (2a)
T all＝T 11+T 12+…+T 1m              (2b)
T all＝T 21+T 22+…+T 2n              (2c)
T all＝(T 11+T 12+…+T 1m+T 21+T 22+…+T 2n)/2    (2d)
T all＝T 测量周期     (2e)
其中，公式(2e)表明，作为一种可能的测量方式，T all的取值为测量周期的取值。
可以理解的是，上述分裂承载的吞吐量是一个测量周期内的测量量，当有多个测量周期时，根据上述一种确定吞吐量的方法，可以获得多个分裂承载的吞吐量，即每个测量周期对应一个分裂承载的吞吐量。
840：第一节点向第二节点发送停止信息，第一节点和第二节点停止吞吐量测量。
其中，在第一节点和第二节点完成K个测量周期内的吞吐量测量情况下，第一节点向第二节点发送停止信息，第一节点和第二节点停止吞吐量测量。其中K为大于等于1的整数，K可以是吞吐量测量的配置信息中携带的参数，也可以是预先设定并分别存储于第一节点和第二节点的。
在另一种可能的实施方式中，第一节点和第二节点在连续K个测量周期内，第一节点/第二节点与终端设备之间无数据传输的情况下，第一节点向第二节点发送停止信息，第一节点和第二节点停止吞吐量测量。
在上述吞吐量计算的方法800中，步骤810可以是可选的，即第一节点可以不用向第二节点发送吞吐量测量的配置信息，吞吐量测量的配置信息可以是第一节点和第二节点预先设定并分别存储于第一节点和第二节点的。
在上述吞吐量计算的方法800中，步骤840可以是可选的，即可以不通过第一节点向第二节点发送停止信息，例如，第一节点和第二节点在完成K个测量周期的吞吐量测量后，停止吞吐量测量，或者，第一节点和第二节点在连续K个测量周期内，第一节点/第二节点与终端设备之间无数据传输，则第一节点和第二节点停止吞吐量测量。其中K为大于等于1的整数，K可以是吞吐量测量的配置信息中携带的参数，也可以是预先设定并分别存储于第一节点和第二节点的。
可以理解，上述吞吐量计算的方法800并未限定数据传输的方向，即上述吞吐量计算的方法800在上行数据传输的场景和下行数据传输的场景均适用。
通过上述吞吐量计算的方法800，可以获得分裂承载的吞吐量，进而通过吞吐量衡量通信系统的性能。
