具体实施方式
为了便于理解本公开，此处对本公开实施例涉及到的部分概念作简单介绍。
1、MDT最小化路测(minimization of drive tests，MDT)，即最小化路测技术。
该技术的基本思想是运营商可以通过签约用户的商用终端设备进行测量上报来部分替代传统的路测工作，以便实现自动收集终端设备的测量数据，从而可以检测和优化无线网络中的问题和故障。运营商一般每个月都要做例行的网络覆盖路测，针对用户投诉也会做一些针对特定区域的呼叫质量路测，这些场景的路测都可以用MDT代替。现有的MDT技术的测量类型可以包括以下几种：
1)、信号水平测量：由终端设备测量无线信号的信号水平，将测量结果上报给接入网设备；
2)、服务质量(quality of service，QoS)测量：可以由接入网设备进行QoS测量，如业务的流量、业务的吞吐量、业务的时延等的测量，也可以由终端设备进行QoS测量，例如，上行处理时延的测量，还可以由接入网设备和终端设备联合进行QoS测量，例如，空口时延测量，即测量数据包经过接入网设备的服务数据适配协议(service data adaptation protocol，SDAP)/包数据汇聚协议(package data convergence protocol，PDCP)层到该数据包到达终端设备的SDAP/PDCP层的时间。
3)、可接入性测量：由终端设备记录RRC连接建立失败的信息，并上报给接入网设备。
MDT可以包括已登录的(logged)MDT和即时(immediate)MDT。immediate MDT主要针对处于RRC连接态(即RRC_CONNECTED)的终端设备进行测量，接入网设备可以指示终端设备进行实时测量和上报。该测量可以包括：
无线资源管理(radio resources management，RRM)测量、物理层(physical，PH)测量、上行链路(up link，UL)PDCP时延测量、体验质量(quality of experience，QoE)测量、无线保真(wireless fidelity，WiFi)测量、蓝牙测量等。RRM测量可以包括参考信号接收功率(reference signal received power，RSRP)测量、参考信号接收质量(reference signal received quality，RSRQ)测量、接收信号强度指示(received signal strength indicator，RSSI)测量等。immediate MDT一般用于测量终端设备的数据量、网络协议(internetprotocol，IP)吞吐率、包传输时延、丢包率、处理时延等。
logged MDT主要针对处于RRC空闲态(即RRC_IDLE)的终端设备或RRC去激活态(即RRC_INACTIVE)的终端设备进行测量。logged MDT测量结果中的每条Logged记录(record)可以包括相对时间戳(relative time stamp)、NR小区全局标识(NR cell globalidentifier，NCGI)、服务小区测量结果、邻区测量结果、无线局域网(wireless local areanetwork，WLAN)测量结果、传感器(sensor)测量结果等。可选地，logged MDT测量结果中的每条Logged记录(record)还可以包括终端设备的位置信息。服务小区测量结果可以包括PCI、小区RSRP/RSRQ、最好波束索引(beam index)、最好波束的RSRP/RSRQ、好波束的数量等。logged MDT一般指终端设备对接收信号强度的测量。
NR中还定义了一些L2测量，用于接入网设备统计一些网络性能，以便进行无线链路管理、无线资源管理、网络维护等功能。这些L2测量是针对一个终端设备进行统计的，如业务的吞吐量、业务的流量、终端设备的处理时延、终端设备的空口时延等。
其中，MDT测量的发起方式可以包括如下两种：
一种是基于信令的MDT(signalling based MDT，SBMDT)测量。基于信令的MDT测量是指针对于某个特定的终端设备所发起的MDT测量，例如由核心网(core network，CN)通知接入网设备以对某个特定的终端设备发起MDT测量。对于基于信令的MDT测量来说，只有当终端设备的使用者同意进行MDT测量(即该终端设备支持MDT测量)时，核心网才会发起针对该终端设备进行MDT测量的消息，否则核心网并不会发起针对该终端设备进行MDT测量的消息。MDT测量的消息中一般会携带一些MDT测量的配置信息、跟踪收集实体或策略收集实体(measurement collection entity，MCE)的IP地址或统一资源标识符(uniform resource identifier，URI)(URI在电脑术语中是一个用于标识某一互联网资源名称的字符串，该标识允许用户通过特定的协议对网络中的资源进行交互操作。URI的最常见的形式是统一资源定位符，URI也经常被指定为一些非正式的网址。还有一些场景中URI被指定为统一资源名称，目的是通过提供一种途径在特定的命名空间资源的标识中补充网址)等信息。MDT测量的配置信息可以包括如下内容中的一项或多项：MDT测量的激活类型(例如可以包括Immediate MDT only类型、Logged MDT only类型和Immediate MDT and Trace类型等)、MDT测量的区域范围、MDT测量的模式(例如immediate MDT模式或logged MDT模式)及该模式的一些配置参数(例如immediate MDT模式的测量事件、logged MDT模式的记录间隔和持续时间等)，基于信令的MDT测量的公共陆地移动(public land mobile network，PLMN)列表。
另一种是基于管理的MDT(management based MDT，MBMDT)测量。基于管理的MDT测量并不是针对某个特定终端设备的MDT测量，而是先由接入网设备从OAM实体或元素管理(element manager，EM)实体接收进行MDT测量的消息，再基于一定的策略从接入该接入网设备的各终端设备中选择合适 的终端设备发起MDT测量。例如，一定的策略可以是指接入网设备只选择那些已经同意进行MDT测量的终端设备发起MDT测量。而每个终端设备是否同意进行MDT测量可以是由核心网提前通知给接入网设备，例如当终端设备的用户同意进行基于管理MDT时，核心网会提前向接入网设备发送指示信息，以指示该终端设备的用户同意进行基于管理的MDT测量，这种情况下，该指示信息可以是“Management Based MDT Allowed indication”。可选地，该指示信息还可以是指示用户同意在哪些PLMN中进行基于管理的MDT，这种情况下，该指示信息还可以为同意进行基于管理MDT的PLMN列表。
需要说明的是，上述所介绍的基于信令的MDT测量和基于管理的MDT测量都可以包括logged MDT模式和immediated MDT模式。
对于基于信令的MDT而言，核心网会把一些MDT配置信息、跟踪收集实体(trace collection entity，TCE)IP地址通知给接入网设备。MDT配置信息可以包括MDT的激活类型、MDT的区域范围、MDT的模式、MDT的模式的配置参数、基于信令的MDT的PLMN列表等。MDT的激活类型可以包括仅限即时MDT(immediate MDT only)、仅限记录的MDT(logged MDT only)、即时MDT和跟踪(immediate MDT and trace)等。MDT的模式的配置参数可以包括immediate MDT的测量事件、logged MDT的记录间隔、logged MDT的持续时间等。
2、跟踪收集实体TCE(Trace Collection Entity，跟踪收集实体)。
本公开实施例中的跟踪收集实体是指能够完成跟踪和收集工作的实体。跟踪收集实体可以是独立于核心网和接入网设备之外的网元或功能实体，也可以是属于核心网或接入网设备中的网元或功能实体，具体不作限定。
为了更好的理解本公开实施例公开的一种测量获取方法和装置，下面首先对本公开实施例适用的通信系统进行描述。
如图1所示，本公开实施例提供了一种通信系统，包括：核心网设备(例如5G核心网(5th generation core，5GC)11、演进型分组核心网(evolved packet core，EPC)12)、接入网设备(例如继续演进的节点B(gNB)13、演进型节点B(evolved node B，eNB)14)、终端设备15。
终端设备15，又称之为用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等，是指向用户提供语音和/或数据连通性的设备。例如，具有无线连接功能的手持式设备、车载设备等。目前，一些终端设备的举例包括：手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internetdevice，MID)、可穿戴设备、虚拟现实(virtual reality，VR)设备、增强现实(augmentedreality，AR)设备、工业控制(industrial control)中的无线终端、无人驾驶(selfdriving)中的无线终端、远程手术(remote medical surgery)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。
核心网设备11，是指为终端设备提供业务支持的核心网(core network，CN)中的设备。目前，一些核心网设备包括：接入和移动性管理功能(access and mobilitymanagement function，AMF)实体、会话管理功能(session management function，SMF)实体、用户面功能(user plane function，UPF)实体等等，此处不一一列举。其中，AMF实体可以负责终端设备的接入管理和移动性管理。SMF实体可以负责会话管理，如用户的会话建立等。UPF实体可以是用户面的功能实体，主要负责连接外部网络。需要说明的是，本公开中实体也可以称为网元或功能实体，例如，AMF实体也可以称为AMF网元或AMF功能实 体，SMF实体也可以称为SMF网元或SMF功能实体等。
接入网设备13，是指将终端设备接入到无线网络的无线接入网(radio accessnetwork，RAN)节点(或设备)，又可以称为基站。目前，一些RAN节点的举例包括：gNB、eNB、传输接收点(transmission reception point，TRP)、无线网络控制器(radio networkcontroller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved NodeB，或homenode B，HNB)、基带单元(base band unit，BBU)，或无线保真(wireless fidelity，Wi-Fi)接入点(access point，AP)等。另外，在一种网络结构中，接入网设备可以包括集中单元(centralized unit，CU)、或分布单元(distributed unit，DU)、或包括CU和DU的RAN设备。其中包括CU和DU的RAN设备从逻辑功能角度将协议层拆分开，部分协议层的功能放在CU集中控制，剩下部分或全部协议层的功能分布在DU中，由CU集中控制DU。
如图2所示，是CU-DU的架构示意图。CU和DU在物理上可以是分离的也可以部署在一起。CU和DU可以根据协议层进行划分，例如其中一种可能的划分方式是：CU用于执行无线资源控制(radio resource control，RRC)层、服务数据适配层(service data adaptationprotocol，SDAP)(本协议层是当接入网设备连接到5G核心网时才具有的协议层)、分组数据汇聚层协议层(packet data convergence protocol，PDCP)的功能，而DU用于执行无线链路控制(radio link control，RLC)层、媒体接入控制(medium access control，MAC)层以及物理(physical，PHY)层等的功能。
可以理解，上述划分仅仅是一种举例，CU和DU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。
在一种可能的实现方式中，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。
在另一种可能的实现方式中，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。
在又一种可能的实现方式中，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，也可以分离设置。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。
应理解，CU和DU的功能可以在具体实现中可以根据需要设置，本公开实施例对此不作任何限定。CU的功能可以由一个实体来实现也可以由不同的功能实体来实现。在一种方式中，CU的功能可以进一步切分为控制面(control plane，CP)功能和用户面(userplane，UP)，即CU可以分为CU-UP和CU-CP。CU-CP和CU-UP可以由不同的功能实体来实现，也可以由同一功能实体来实现。CU-CP和CU-UP可以与DU相耦合，共同完成接入网设备的功能。一种可能的方式中，CU-CP负责控制面功能，主要包含RRC和PDCP-C。PDCP-C主要负责控制面数据的加解密、完整性保护以及数据传输等。CU-UP负责用户面功能，主要包含SDAP和PDCP-U。其中SDAP主要负责将核心网设备的数据进行处理并将数据流(flow)映射到承载。PDCP-U主要负责数据面的加解密、完整性保护、头压缩、序列号维护以及数据传输等。还有一种可能的实现方式是PDCP-C也包含在CU-UP中。
核心网设备与CU(例如CU-UP和/或CU-CP)之间可以进行通信，例如，CU-CP可以代表接入网设备通过Ng接口与核心网设备进行通信。CU-UP与CU-CP之间可以进行通信，例如，通过E1接口进行 通信。CU-UP与DU之间以及CU-CP与DU之间可以进行通信，例如，CU-CP可以通过F1-C(控制面)与DU进行通信，CU-UP可以通过F1-U(用户面)与DU进行通信。多个DU可以共用一个CU，一个DU也可以连接多个CU(图中未示出)。CU与DU之间可以通过接口(例如F1接口)进行通信。
在本公开实施例中，一个终端设备可以通过MR-DC(multi-RAT dualconnectivity，多无线电双连接)与多个接入网设备通信。MR-DC中与核心网有控制面信令交互的接入网设备(基站)称为MN(Master Node，主节点)，其他基站称为SN(Secondary Node，辅节点)。MN中包括主小区组(mastercell group，MCG)，MCG至少包括一个PCell，还可以包括至少一个辅小区(secondary cell，SCell)，这些小区都称为终端设备的MCG服务小区。SN中包括辅小区组(secondary cellgroup，SCG)，SCG至少包括一个PSCell，还可以包括至少一个SCell，这些小区都称为终端设备的SCG服务小区。终端设备的MCG服务小区和SCG服务小区都称为终端设备的服务小区。其中，MCG中各个小区对应的频点称为终端设备的MCG服务频点(也可以称为MN服务频点)。SCG中各个小区对应的频点称为终端设备的SCG服务频点(也可以称为SN服务频点)。这些频点都称为终端设备的服务频点。
对于一个终端设备来说，组成MR-DC的多个接入网设备可能属于同一无线接入技术(radio access technology，RAT)，例如都属于第四代(4th generation，4G)通信技术中的通用陆基无线接入技术(evolved universal terrestrial radio access，E-UTRA)或者都属于5G中的新无线(new radio，NR)接入技术。组成MR-DC的多个接入网设备也可能属于不同RAT，例如一个属于E-UTRA，另一个属于NR。网络侧可以利用多个接入网设备的资源为该终端设备提供通信服务，从而为终端设备提供高传输速率。
可以理解的是，本公开实施例描述的通信系统是为了更加清楚的说明本公开实施例的技术方案，并不构成对于本公开实施例提供的技术方案的限定，本领域普通技术人员可知，随着系统架构的演变和新业务场景的出现，本公开实施例提供的技术方案对于类似的技术问题，同样适用。
下面结合附图对本公开所提供的一种测量获取方法和装置进行详细地介绍。
请参见图3，图3是本公开实施例提供的一种测量获取方法的流程图。
如图3所示，该方法由第二节点执行，该方法可以包括但不限于如下步骤：
S31：接收第一节点发送的第一测量的收集请求。
可以理解的是，相关技术中，第三节点发起配置在第二节点上激活第一测量，并且第二节点生成第一测量的测量结果，可以上报至第三节点。然而，对于不同于第三节点的第一节点，无法获知第二节点中激活的测量信息和生成的测量结果。
基于此，本公开实施例中，第一节点可以向第二节点发送第一测量的收集请求，以请求获取第二节点中激活的测量信息和/或生成的测量结果。在一些实施例中，收集请求，包括以下至少一项：
开始收集指示；
停止收集指示；
收集的时间信息；
需要收集的特定小区的小区标识；
需要收集的第一测量的测量标识；
需要收集的终端设备的终端设备标识；
需要收集的第一测量的测量内容；
测量报告的上报方式。
其中，开始收集指示或停止收集指示，用于指示第一测量的测量结果的收集开始或停止，如果是开始收集指示，第二节点会开始向第一节点传输第一测量的测量结果；如果是停止收集指示，第二节点停止向第一节点传输第一测量的测量结果。
收集的时间信息，用于指示第一测量的测量结果的收集时间长度，当第二节点开始向第一节点传输第一测量的测量结果后，经过收集的时间信息，第二节点停止向第一节点传输第一测量的结果。
需要收集的特定小区的小区标识，用于指示需要收集哪个特定小区的第一测量，例如可用是PCI(physical cell identifier，物理小区标识)或CGI(Cell Global Identity，小区全局标识)。
需要收集的第一测量的测量标识，用于指示需要收集的第一测量的ID，例如跟踪参考Trace Reference，或跟踪记录会话参考Trace Session Recording Reference等。
需要收集的终端设备的终端设备标识，用于指示需要收集的终端设备的终端设备标识，例如可以是终端设备F1AP(F1 Application Proposal，F1应用协议)ID，终端设备E1AP(E1 Application Proposal，E1应用协议)ID，终端设备XNAP(Xn Application Proposal，Xn应用协议)ID或C-RNTI(Cell Radio Network Temporary Identify，小区无线网络临时标识)等在无线接入网中标识终端设备的ID。
需要收集的第一测量的测量内容，用于指示需要收集的第一测量内容的测量结果。根据一种实施例，需要收集的第一测量的测量内容可以是一种比特位图，每一个比特代表一种测量的内容，值为“1”则代表需要收集的第一测量的测量内容对应的测量结果需要被第一节点收集，值为“0”则代表需要收集的第一测量的测量内容对应的测量数据或结果不需要被第一节点收集，需要收集的第一测量的测量内容可以包括但不限于MDT的M2(功率余量)，M5(UE平均吞吐量)，M6(包延迟)，M7(丢包率)，CQI(channel quality indictor，信道质量指示)，PHR(powerheadroomreport，功率余量报告)，UL interference上行干扰等。
测量报告的上报方式，用于指示第二节点何时向第一节点发送收集的第一测量报告，例如可以是根据预配置的测量周期上报、或者也可以是按第一节点定义的周期进行上报、或者也可以是在会话结束的时候进行上报(例如终端设备或承载的上下文被释放时上报)。
在一些实施例中，上述被第一测量的收集请求包括的信息可以是一个信息列表，每一个列表中包括一个或多个上述信息。
第二节点接收收集请求，第二节点考虑收集请求，向第一节点发送请求的第一测量的测量结果。第一节点向第二节点发送收集请求可以让第二节点有针对性地上报对应的第一测量的测量结果，或按照特定的上报方式进行上报，让第一测量的测量结果收集更加地灵活，可以减少不必要的收集和信令开销。
在一些实施例中，第一节点为集中单元控制面CU-CP，第二节点为中央单元用户面CU-UP。
在另一些实施例中，第一节点为主节点MN，第二节点为辅节点SN。
在又一些实施例中，第一节点为集中单元CU，第二节点为分布单元DU。
在一些实施例中，收集请求使用与终端设备相关的信令消息进行传输。
本公开实施例中，第一测量的收集请求使用与终端设备相关的信令消息进行传输，根据一种实施例，第一节点是CU-CP，第二节点是DU，收集请求被包括在CU-CP发送给DU的终端设备上下文建立请求消息、终端设备上下文修改请求消息、终端设备上下文修改确认消息、MDT收集请求消息或其他终端设备相关的F1AP(F1 Application Proposal，F1应用协议)消息中；根据另一实施例，第一节点是CU-CP， 第二节点是CU-UP，第一测量的收集请求被包括在CU-CP发送给CU-UP的承载上下文建立请求消息、承载上下文修改请求消息、承载上下文修改确认消息、MDT收集请求消息或其他终端设备相关的E1AP(E1 Application Proposal，E1应用协议)消息中；根据又一实施例，第一节点是DC场景下的MN，第二节点是DC场景的SN，第一测量的收集请求被包括在MN发送给SN的SN添加请求消息、SN修改请求消息、SN修改确认消息、MDT收集请求消息、Trace收集请求消息、测量收集请求消息或其他终端设备相关的XnAP(Xn Application Proposal，Xn应用协议)消息中。应当理解，以上仅为示例，第一节点、第二节点和包括第一测量的收集请求的消息不限于此。
在一些实施例中，收集请求使用与终端设备不相关的信令消息进行传输。
本公开实施例中，第一测量的收集请求使用与终端设备不相关的信令消息进行传输，根据一种实施例，第一节点是CU-CP，第二节点是DU，第一测量的收集请求的信息被包括在CU-CP发送给DU的F1 SETUP RESPONSE消息、GNB-CU CONFIGURATION UPDATE消息、第一测量的收集请求消息或其他与终端设备不相关的F1AP消息中；根据另一实施例，第一节点是CU-CP，第二节点是CU-UP，第一测量的收集请求包括在CU-CP发送给CU-UP的GNB-CU-CP E1 SETUP REQUEST消息、GNB-CU-UP E1 SETUP RESPONSE消息、GNB-CU-CP CONFIGURATION UPDATE消息、第一测量收集的请求消息或其他与终端设备不相关的E1AP消息中；根据又一实施例，第一节点是DC场景下的MN，第二节点是DC场景的SN，第一测量的收集请求被包括在MN发送给SN的XN SETUP REQUEST消息、XN SETUP RESPONSE消息、NG-RAN NODE CONFIGURATION UPDATE消息、NG-RAN NODE CONFIGURATION UPDATE ACKNOWLEDGE消息、第一测量的收集请求消息或其他与终端设备不相关的XnAP消息中。应当理解，以上仅为示例，第一节点、第二节点和包括第一测量的收集请求的消息不限于此。
在一些实施例中，第一测量，包括以下至少一种：
基于管理的最小化路测MDT；
小区话务跟踪Cell Traffic Trace；
终端设备跟踪UE Trace。
可以理解的是，MDT可以用于收集终端设备的测量信息和接入网设备侧终端设备相关的测量信息。MDT分为基于信令的MDT(signalling-based MDT)和基于管理的MDT(management-based MDT)。如果是基于管理的MDT，MDT数据是从指定区域的终端设备上采集的，该区域被定义为小区列表或跟踪/路由/位置区域列表，基于管理的MDT是基于管理的跟踪功能的增强。如果是基于信令的MDT，MDT数据是从一个特定的终端设备收集的，参与MDT数据采集的终端是用国际移动设备识别码(International Mobile Equipment Identity，IMEI)或IMEI软件版本来指定的，基于信令的MDT是基于信令的跟踪功能的增强。
如果是基于管理的MDT，在CU-DU分离架构下，EM可以直接向gNB-DU(以下简称DU)或gNB-CU-CP(以下简称CU-CP)或gNB-CU-UP(以下简称CU-UP)发送激活MDT配置。
如图4所示，图4为gNB-DU中基于管理的MDT激活信令流程(gNB-CU-UP中基于管理的MDT激活流程与之类似)。
如果基于管理的MDT是在gNB-DU中激活的(如步骤3所示)，且终端设备被选择执行MDT,当有匿名化参数指被设置成IMEI-TAC(International Mobile Equipment Identity-Type Allocation Code)时， 那么gNB-DU才会向gNB-CU-CP发送Cell Trace Traffic以通知gNB-CU-CP被选择终端设备的Trace ID(如步骤4)，以便gNB-CU-CP通知核心网(如步骤5)，核心网再将终端设备ID和Trace ID进行关联发送到TCE，否则，gNB-DU不会向gNB-CU-CP发任何关于MDT的信息。而gNB-DU在收集完MDT后，会将MDT报告、Cell Traffic Trace报告或终端设备Trace报告发送给TCE，这样TCE就可以对测量结果进行进一步分析了，但是对于CU-CP，对整个过程是不可知的，即CU-CP不知道DU或CU-UP开始MDT测量和具体的测量内容(注意图4中第四步可能发生或不发生，即使是发生了，也并不知道进行了哪些类型的测量)，因此，相关技术中不支持CU-CP从DU或CU-UP获取MDT的测量信息和测量结果。
本公开实施例中，第一节点(CU-CP)可以向第二节点(CU-UP)发送第一测量(MDT)的收集请求，可以请求获取MDT的测量信息和测量结果。
本公开实施例中，第一节点(CU)可以向第二节点(DU)发送第一测量(MDT)的收集请求，可以请求获取MDT的测量信息和测量结果。
当然，对于相关技术中，基于管理的MDT由OAM直接在SN中激活，不支持MN从SN获取MDT的测量信息和测量结果的情况，本公开实施例中，第一节点(MN)可以向第二节点(SN)发送第一测量(MDT)的收集请求，可以请求获取MDT的测量信息和测量结果。
另外，本公开实施例中，第一测量还可以为小区话务跟踪Cell Traffic Trace，小区话务跟踪Cell Traffic Trace在第二节点中激活，第一节点可以向第二节点发送小区话务跟踪Cell Traffic Trace的收集请求，可以请求获取小区话务跟踪Cell Traffic Trace的测量信息和测量结果。其中，第一节点为CU-CP，第二节点为CU-UP，或者第一节点为CU，第二节点为DU，或者第一节点为MN，第二节点为SN。
本公开实施例中，第一测量还可以为终端设备跟踪UE Trace，终端设备跟踪UE Trace在第二节点中激活，第一节点可以向第二节点发送终端设备跟踪UE Trace的收集请求，可以请求获取终端设备跟踪UE Trace的测量信息和测量结果。其中，第一节点为CU-CP，第二节点为CU-UP，或者第一节点为CU，第二节点为DU，或者第一节点为MN，第二节点为SN。
S32：向第一节点发送第一测量的收集反馈，其中，第一测量是由第三节点发起配置，并在第二节点上激活的，第一节点不同于第三节点。
本公开实施例中，第二节点接收到第一节点发送的第一测量的收集请求之后，可以向第一节点发送第一测量的收集反馈。
其中，第一测量是由第三节点发起配置，并在第二节点上激活的，第三节点可以是OAM(operation,administration and maintenance，操作、管理和维护)或EM(elementmanager，元素管理)。
在一些实施例中，收集反馈包括第一测量的测量报告，测量报告，包括以下至少一项：
测量结果对应的测量标识；
测量结果对应的终端设备的终端设备标识；
测量结果；
测量结果对应的特定小区的小区标识；
测量结果对应的测量开始时间；
测量结果对应的测量结束时间。
本公开实施例中，第二节点向第一节点发送第一测量的收集反馈，收集反馈中包括一个或多个第一 测量的测量结果(或者也可称为测量报告，例如MDT报告、Cell Traffic Trace报告或终端设备Trace报告)。
其中，测量报告包括测量结果对应的测量标识，用于指示测量报告中的测量结果对应的第一测量ID，例如Trace ID。
测量报告包括测量结果对应的终端设备的终端设备标识，用于指示测量报告中的测量结果对应的终端设备，例如可以是终端设备F1AP ID，终端设备E1AP ID，终端设备XNAP ID或C-RNTI等在无线接入网中标识终端设备的ID。
测量报告包括测量结果，例如MDT报告Cell Traffic Trace报告或终端设备Trace报告，测量结果可以包括一个或多个测量内容的测量结果和/或测量报告生成的时间。
测量报告包括测量结果对应的特定小区的小区标识，用于指示反馈的第一测量是哪个小区的，例如可用是PCI或CGI。
测量报告包括测量结果对应的测量开始时间和/或测量结果对应的测量结束时间，用于指示第一测量的测量结果中对应的测量的开始时间和/或结束时间，例如可以是时间戳的形式。第一节点可以通过具体的测量时间来关联来自其他节点的测量信息，从而对整体的数据收集进行分析。
在一些实施例中，收集反馈使用与终端设备相关的信令消息进行传输。
在一些实施例中，收集反馈使用与终端设备不相关的信令消息进行传输。
本公开实施例中，第一测量的收集反馈是由与终端设备相关的信令消息或与终端设备不相关的信令消息传输的，根据一种实施例，第一节点是CU-CP，第二节点是DU，第一测量的收集反馈被包括在DU发送给CU-CP的第一测量的收集反馈消息、MDT报告、Cell Traffic Trace报告或终端设备Trace报告或其他F1AP消息中；根据另一实施例，第一节点是CU-CP，第二节点是CU-UP，第一测量的收集反馈被包括在CU-UP发送给CU-CP的第一测量的收集反馈消息、MDT报告、Cell Traffic Trace报告或终端设备Trace报告或其他E1AP消息中；根据又一实施例，第一节点是DC场景下的MN，第二节点是DC场景的SN，第一测量的收集反馈被包括在MN发送给SN的第一测量的收集反馈消息、MDT报告、Cell Traffic Trace报告或终端设备Trace报告或其他XnAP消息中。应当理解，以上仅为示例，第一节点、第二节点和包括收集反馈的消息不限于此。
在TR 37.817中，在CU-DU分离架构下，AI模型的训练和推理都在gNB-CU执行，在DC场景下，AI模型的训练和推理在MN进行，而终端设备相关的测量信息会作为AI模型训练和推理的输入或AI模型的性能反馈。其中，终端设备相关的测量信息可以利用相关技术中的MDT测量来实现。
当AI的训练模型和推理在CU-CP或MN，根据相关技术中的Trace/MDT机制，如果管理的Trace/MDT在DU或CU-UP或SN中激活，DU或CU-UP或SN在选择终端设备后开始测量，并将MDT报告、Cell Traffic Trace报告或终端设备Trace报告直接发送给OAM(例如OAM中的TCE)，CU-CP对这个过程是不可知的，即CU-CP并不知道DU或CU-UP开始了MDT测量和具体的测量内容(例如图4中第四步可能发生或不发生，即使是发生了，也并不知道进行了哪些类型的测量)，因此，Trace/MDT机制不支持CU-CP从DU或CU-UP获取MDT的测量信息和测量结果，同样，现有Trace/MDT机制也不支持MN从SN获取Trace/MDT的测量信息和测量结果。
基于此，本公开实施例中，如果基于管理的MDT在第二节点上激活，而第一节点作为负责AI模型训练或推理的节点，需要从第二节点收集MDT测量报告，通过本公开实施例提供的方法，可以让第 二节点考虑到第一节点有AI收集的需求而有针对性地选择终端设备进行MDT测量，也能让第一节点及时地获取到在第二节点上激活的MDT的详细信息，例如是否被配置或激活、具体被配置或激活的MDT测量内容的信息、和/或需要收集的MDT测量报告，以便更有针对性地选择收集MDT测量数据，用于AI相关的操作。
其中，在CU-DU分离架构下，第一节点是CU或CU-CP，第二节点是DU或CU-UP；在双连接场景下，第一节点是MN，第二节点是SN。

请参见图7，图7是本公开实施例提供的又一种测量获取方法的流程图。
如图7所示，该方法由第一节点执行，该方法可以包括但不限于如下步骤：
S71：向第二节点发送第一测量的收集请求。
可以理解的是，相关技术中，第三节点发起配置在第二节点上激活第一测量，并且第二节点生成第一测量的测量结果，可以上报至第三节点。然而，对于不同于第三节点的第一节点，无法获知第二节点中激活的测量信息和生成的测量结果。
基于此，本公开实施例中，第一节点可以向第二节点发送第一测量的收集请求，以请求获取第二节点中激活的测量信息和/或生成的测量结果。

在另一些实施例中，第一节点为主节点MN，第二节点为辅节点SN。
在又一些实施例中，第一节点为集中单元CU，第二节点为分布单元DU。
在一些实施例中，收集请求使用与终端设备相关的信令消息进行传输。
本公开实施例中，第一测量的收集请求使用与终端设备相关的信令消息进行传输，根据一种实施例，第一节点是CU-CP，第二节点是DU，收集请求被包括在CU-CP发送给DU的终端设备上下文建立请求消息、终端设备上下文修改请求消息、终端设备上下文修改确认消息、MDT收集请求消息或其他终端设备相关的F1AP(F1 Application Proposal，F1应用协议)消息中；根据另一实施例，第一节点是CU-CP，第二节点是CU-UP，第一测量的收集请求被包括在CU-CP发送给CU-UP的承载上下文建立请求消息、承载上下文修改请求消息、承载上下文修改确认消息、MDT收集请求消息或其他终端设备相关的E1AP(E1 Application Proposal，E1应用协议)消息中；根据又一实施例，第一节点是DC场景下的MN，第 二节点是DC场景的SN，第一测量的收集请求被包括在MN发送给SN的SN添加请求消息、SN修改请求消息、SN修改确认消息、MDT收集请求消息、Trace收集请求消息、测量收集请求消息或其他终端设备相关的XnAP(Xn Application Proposal，Xn应用协议)消息中。应当理解，以上仅为示例，第一节点、第二节点和包括第一测量的收集请求的消息不限于此。
在一些实施例中，收集请求使用与终端设备不相关的信令消息进行传输。
本公开实施例中，第一测量的收集请求使用与终端设备不相关的信令消息进行传输，根据一种实施例，第一节点是CU-CP，第二节点是DU，第一测量的收集请求的信息被包括在CU-CP发送给DU的F1 SETUP RESPONSE消息、GNB-CU CONFIGURATION UPDATE消息、第一测量的收集请求消息或其他与终端设备不相关的F1AP消息中；根据另一实施例，第一节点是CU-CP，第二节点是CU-UP，第一测量的收集请求包括在CU-CP发送给CU-UP的GNB-CU-CP E1 SETUP REQUEST消息、GNB-CU-UP E1 SETUP RESPONSE消息、GNB-CU-CP CONFIGURATION UPDATE消息、第一测量收集的请求消息或其他与终端设备不相关的E1AP消息中；根据又一实施例，第一节点是DC场景下的MN，第二节点是DC场景的SN，第一测量的收集请求被包括在MN发送给SN的XN SETUP REQUEST消息、XN SETUP RESPONSE消息、NG-RAN NODE CONFIGURATION UPDATE消息、NG-RAN NODE CONFIGURATION UPDATE ACKNOWLEDGE消息、第一测量的收集请求消息或其他与终端设备不相关的XnAP消息中。应当理解，以上仅为示例，第一节点、第二节点和包括第一测量的收集请求的消息不限于此。
在一些实施例中，第一测量，包括以下至少一种：
基于管理的最小化路测MDT；
小区话务跟踪Cell Traffic Trace；
终端设备跟踪UE Trace。
可以理解的是，MDT可以用于收集终端设备的测量信息和接入网设备侧终端设备相关的测量信息。MDT分为基于信令的MDT(signalling-based MDT)和基于管理的MDT(management-based MDT)。如果是基于管理的MDT，MDT数据是从指定区域的终端设备上采集的，该区域被定义为小区列表或跟踪/路由/位置区域列表，基于管理的MDT是基于管理的跟踪功能的增强。如果是基于信令的MDT，MDT数据是从一个特定的终端设备收集的，参与MDT数据采集的终端是用国际移动设备识别码(International Mobile Equipment Identity，IMEI)或IMEI软件版本来指定的，基于信令的MDT是基于信令的跟踪功能的增强。
如果是基于管理的MDT，在CU-DU分离架构下，EM可以直接向gNB-DU(以下简称DU)或gNB-CU-CP(以下简称CU-CP)或gNB-CU-UP(以下简称CU-UP)发送激活MDT配置。
如图4所示，图4为gNB-DU中基于管理的MDT激活信令流程(gNB-CU-UP中基于管理的MDT激活流程与之类似)。
如果基于管理的MDT是在gNB-DU中激活的(如步骤3所示)，且终端设备被选择执行MDT,当有匿名化参数指被设置成IMEI-TAC(International Mobile Equipment Identity-Type Allocation Code)时，那么gNB-DU才会向gNB-CU-CP发送Cell Trace Traffic以通知gNB-CU-CP被选择终端设备的Trace ID(如步骤4)，以便gNB-CU-CP通知核心网(如步骤5)，核心网再将终端设备ID和Trace ID进行关联发送到TCE，否则，gNB-DU不会向gNB-CU-CP发任何关于MDT的信息。而gNB-DU在收集完 MDT后，会将MDT报告、Cell Traffic Trace报告或终端设备Trace报告发送给TCE，这样TCE就可以对测量结果进行进一步分析了，但是对于CU-CP，对整个过程是不可知的，即CU-CP不知道DU或CU-UP开始MDT测量和具体的测量内容(注意图4中第四步可能发生或不发生，即使是发生了，也并不知道进行了哪些类型的测量)，因此，相关技术中不支持CU-CP从DU或CU-UP获取MDT的测量信息和测量结果。
本公开实施例中，第一节点(CU-CP)可以向第二节点(CU-UP)发送第一测量(MDT)的收集请求，可以请求获取MDT的测量信息和测量结果。
本公开实施例中，第一节点(CU)可以向第二节点(DU)发送第一测量(MDT)的收集请求，可以请求获取MDT的测量信息和测量结果。
当然，对于相关技术中，基于管理的MDT由OAM直接在SN中激活，不支持MN从SN获取MDT的测量信息和测量结果的情况，本公开实施例中，第一节点(MN)可以向第二节点(SN)发送第一测量(MDT)的收集请求，可以请求获取MDT的测量信息和测量结果。
另外，本公开实施例中，第一测量还可以为小区话务跟踪Cell Traffic Trace，小区话务跟踪Cell Traffic Trace在第二节点中激活，第一节点可以向第二节点发送小区话务跟踪Cell Traffic Trace的收集请求，可以请求获取小区话务跟踪Cell Traffic Trace的测量信息和测量结果。其中，第一节点为CU-CP，第二节点为CU-UP，或者第一节点为CU，第二节点为DU，或者第一节点为MN，第二节点为SN。
本公开实施例中，第一测量还可以为终端设备跟踪UE Trace，终端设备跟踪UE Trace在第二节点中激活，第一节点可以向第二节点发送终端设备跟踪UE Trace的收集请求，可以请求获取终端设备跟踪UE Trace的测量信息和测量结果。其中，第一节点为CU-CP，第二节点为CU-UP，或者第一节点为CU，第二节点为DU，或者第一节点为MN，第二节点为SN。
S72：接收第二节点发送的第一测量的收集反馈，其中，第一测量是由第三节点发起配置，并在第二节点上激活的，第一节点不同于第三节点。
本公开实施例中，第二节点接收到第一节点发送的第一测量的收集请求之后，可以向第一节点发送第一测量的收集反馈。
其中，第一测量是由第三节点发起配置，并在第二节点上激活的，第三节点可以是OAM(operation,administration and maintenance，操作、管理和维护)或EM(elementmanager，元素管理)。
在一些实施例中，收集反馈包括第一测量的测量报告，测量报告，包括以下至少一项：
测量结果对应的测量标识；
测量结果对应的终端设备的终端设备标识；
测量结果；
测量结果对应的特定小区的小区标识；

测量结果对应的测量结束时间。
本公开实施例中，第二节点向第一节点发送第一测量的收集反馈，收集反馈中包括一个或多个第一测量的测量结果(或者也可称为测量报告，例如MDT报告、Cell Traffic Trace报告或终端设备Trace报告)。
其中，测量报告包括测量结果对应的测量标识，用于指示测量报告中的测量结果对应的第一测量 ID，例如Trace ID。
测量报告包括测量结果对应的终端设备的终端设备标识，用于指示测量报告中的测量结果对应的终端设备，例如可以是终端设备F1AP ID，终端设备E1AP ID，终端设备XNAP ID或C-RNTI等在无线接入网中标识终端设备的ID。
测量报告包括测量结果，例如MDT报告、Cell Traffic Trace报告或终端设备Trace报告，测量结果可以包括一个或多个测量内容的测量结果和/或测量报告生成的时间。
测量报告包括测量结果对应的特定小区的小区标识，用于指示反馈的第一测量是哪个小区的，例如可用是PCI或CGI。
测量报告包括测量结果对应的测量开始时间和/或测量结果对应的测量结束时间，用于指示第一测量的测量结果中对应的测量的开始时间和/或结束时间，例如可以是时间戳的形式。第一节点可以通过具体的测量时间来关联来自其他节点的测量信息，从而对整体的数据收集进行分析。
在一些实施例中，收集反馈使用与终端设备相关的信令消息进行传输。
在一些实施例中，收集反馈使用与终端设备不相关的信令消息进行传输。
本公开实施例中，第一测量的收集反馈是由与终端设备相关的信令消息或与终端设备不相关的信令消息传输的，根据一种实施例，第一节点是CU-CP，第二节点是DU，第一测量的收集反馈被包括在DU发送给CU-CP的第一测量的收集反馈消息、MDT报告、Cell Traffic Trace报告或终端设备Trace报告或其他F1AP消息中；根据另一实施例，第一节点是CU-CP，第二节点是CU-UP，第一测量的收集反馈被包括在CU-UP发送给CU-CP的第一测量的收集反馈消息、MDT报告、Cell Traffic Trace报告或终端设备Trace报告或其他E1AP消息中；根据又一实施例，第一节点是DC场景下的MN，第二节点是DC场景的SN，第一测量的收集反馈被包括在MN发送给SN的第一测量的收集反馈消息、MDT报告、Cell Traffic Trace报告或终端设备Trace报告或其他XnAP消息中。应当理解，以上仅为示例，第一节点、第二节点和包括收集反馈的消息不限于此。
在TR 37.817中，在CU-DU分离架构下，AI模型的训练和推理都在gNB-CU执行，在DC场景下，AI模型的训练和推理在MN进行，而终端设备相关的测量信息会作为AI模型训练和推理的输入或AI模型的性能反馈。其中，终端设备相关的测量信息可以利用相关技术中的MDT测量来实现。
当AI的训练模型和推理在CU-CP或MN，根据相关技术中的Trace/MDT机制，如果管理的Trace/MDT在DU或CU-UP或SN中激活，DU或CU-UP或SN在选择终端设备后开始测量，并将MDT报告、Cell Traffic Trace报告或终端设备Trace报告直接发送给OAM(例如OAM中的TCE)，CU-CP对这个过程是不可知的，即CU-CP并不知道DU或CU-UP开始了MDT测量和具体的测量内容(例如图4中第四步可能发生或不发生，即使是发生了，也并不知道进行了哪些类型的测量)，因此，Trace/MDT机制不支持CU-CP从DU或CU-UP获取Trace/MDT的测量信息和测量结果，同样，现有Trace/MDT机制也不支持MN从SN获取Trace/MDT的测量信息和测量结果。
基于此，本公开实施例中，如果基于管理的MDT在第二节点上激活，而第一节点作为负责AI模型训练或推理的节点，需要从第二节点收集MDT测量报告，通过本公开实施例提供的方法，可以让第二节点考虑到第一节点有AI收集的需求而有针对性地选择终端设备进行MDT测量，也能让第一节点及时地获取到在第二节点上激活的MDT的详细信息，例如是否被配置或激活、具体被配置或激活的MDT测量内容的信息、和/或需要收集的MDT测量报告，以便更有针对性地选择收集MDT测量数据， 用于AI相关的操作。
其中，在CU-DU分离架构下，第一节点是CU或CU-CP，第二节点是DU或CU-UP；在双连接场景下，第一节点是MN，第二节点是SN。
在一些实施例中，第一节点根据收集反馈，执行以下至少一个：
模型训练；

本公开实施例中，第一节点接收收集反馈。在一些实施例中，第一节点将收集反馈作为输入用于模型训练、模型推理和/或模型性能反馈，能够让模型的训练、推理等更加准确，其中，模型可以为AI(Artificial Intelligence，人工智能)模型，从而能让接入网设备做出更好的负载均衡、网络节能和/或移动性优化决策，提升用户体验，降低网络能耗。
通过实施本公开实施例，在CU-DU或CP-UP分离架构下或双连接场景下，能让执行AI模型训练、推理和/或性能反馈的节点获取其他节点上终端设备测量是否可用的信息和/或收集其他节点上的终端设备测量信息，并且本方法能让AI模型训练、推理和/或性能反馈的数据收集多样、灵活、且有针对性，从而让AI模型的训练和/或推理更加准确，通过更准确的AI模型，实现更优的网络优化方案，例如负载均衡、网络节能、移动性优化等，从而既能保证或提升用户体验，提升用户忠诚度从而提高运营收益，同时也能节约网络能耗，降低运营商成本。
通过实施本公开实施例，第一节点向第二节点发送第一测量的收集请求；接收第二节点发送的第一测量的收集反馈，其中，第一测量是由第三节点发起配置，并在第二节点上激活的，第一节点不同于第三节点。由此，第一节点可以获取第二节点中激活的第一测量的信息，以及第一测量的测量结果。
可以理解的是，在CU-DU分离架构下，第一节点为CU，第二节点为DU，Trace为OAM通过CU配置给DU的，CU可以知晓DU中关于Trace(小区话务跟踪Cell Traffic Trace和/或终端设备跟踪UE Trace)的测量内容。在此情况下，CU可以直接向DU发送Trace的测量的收集请求，进而接收DU发送的收集反馈，以获取Trace的测量信息和/或测量结果。
其中，在第一节点为CU，第二节点为DU，第一测量为基于管理的MDT的情况下，第二节点可以预先向第一节点发送用于确定收集请求的第一测量的可用性信息，以使第一节点可以获取第一测量的可用性信息，进而有针对性的选择特定的终端设备和/或特定的测量内容进行测量结果的收集，向第二节点发送收集请求。
此外，对于情况一：第一节点为CU-CP，第二节点为CU-UP，第一测量为基于管理的MDT；情况二：第一节点为CU-CP，第二节点为CU-UP，第一测量为Trace(小区话务跟踪Cell Traffic Trace和/或终端设备跟踪UE Trace)；情况三：第一节点为MN，第二节点为SN，第一测量为基于管理的MDT；情况四：第一节点为MN，第二节点为SN，第一测量为Trace(小区话务跟踪Cell Traffic Trace和/或终端设备跟踪UE Trace)，第二节点均可以预先向第一节点发送用于确定收集请求的第一测量的可用性信息，以使第一节点可以获取第一测量的可用性信息，进而有针对性的选择特定的终端设备和/或特定的测量内容进行测量结果的收集，向第二节点发送收集请求。
在一些实施例中，第二节点向第一节点发送用于确定收集请求的第一测量的可用性信息。
可以理解的是，第二节点在接收第一节点发送的第一测量的收集请求之前，可以向第一节点发送第 一测量的可用性信息，以指示可以获取的第一测量的可用性信息。从而，第一节点可以根据可用性信息，确定向第二节点发送的收集请求。
