作为示例而非限定，在本申请实施例中，该终端设备还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能首饰等。
此外，在本申请实施例中，终端设备还可以是物联网(internet of things，IoT)系统中的终端设备，IoT是未来信息技术发展的重要组成部分，其主要技术特点是将物品通过通信技术与网络连接，从而实现人机互连，物物互连的智能化网络。本申请的终端设备还可以是作为一个或多个部件或者单元而内置于车辆的车载单元、车载模组、车载部件、车载芯片或者车载单元，车辆通过内置的所述车载单元、车载模组、车载部件、车载芯片或者车载单元可以实施本申请的方法。因此，本申请实施例可以应用于车联网，例如车辆外联(vehicle to everything，V2X)、车间通信长期演进技术(long term evolution-vehicle，LTE-V)、车到车(vehicle-to-vehicle，V2V)等。

本申请实施例中的核心网设备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，上述核心网设备可以为：接入和移动性管理功能(access and mobility management 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，上述AMF实体可以负责终端设备的接入管理和移动性管理；上述SMF实体可以负责会话管理，如用户的会话建立等；上述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，本申请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，又例如，SMF实体也可以称为SMF网元或SMF功能实体等，本申请对此不作限定。
图2为本申请实施例提供的系统架构200示意图。如图2所示，系统架构200包括核心网设备201、终端设备202、接入网设备203接入网设备204。其中，核心网设备201可以为终端设备202提供业务支持的核心网，该核心网可以给终端设备202提供连接、对终端设备202的管理以及对业务完成承载，作为承载网络提供到外部网络的接口。接入网设备203和接入网设备204主要用于核心网设备201和终端设备202之间的交叉连接、复用和传输。终端设备202可以通过接入网设备203或接入网设备204接收传输资源(例如，频域资源，或者说，频谱资源)与小区进行通信，该小区可以属于宏基站(例如，宏eNB或宏gNB等)，也可以属于小小区(small cell)对应的基站，这里的小小区可以包括：城市小区(metro cell)、微小区(micro cell)、微微小区(pico cell)、毫微微小区(femto cell)等，这些小小区具有覆盖范围小、发射 功率低的特点，适用于提供高速率的数据传输服务。
运营商一般每一个月都要做例行的网络覆盖路测，或者针对用户的投诉也会做一些针对特定区域的进行呼叫质量路测，并根据测量结果检测和优化无线网络中的问题和故障。为实现自动收集终端测量数据，进而提高网络优化效率，目前上述路测都可以使用最小化路测(minimization of drive-tests,MDT)代替，该技术的基本思想是运营商通过签约用户的商用终端设备进行测量并发送测量结果来部分替代传统的路测工作。
现有的MDT技术的测量类型可分为以下几种：
1、信号水平测量：由终端设备测量无线信号的信号水平，将测量结果发送给接入网设备。
2、服务质量(quality of service，Qos)测量：通常由接入网设备执行Qos测量，比如：业务的流量、业务的吞吐量，业务时延等，或者由终端设备测量上行处理时延等，也可以是接入网设备和终端设备联合测量空口时延，即测量数据包经过接入网设备的SDAP层/PDCP层到该数据包达到终端设备的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，并发送给接入网设备。
但是对于一些流类业务或者语音业务而言，比如流媒体服务(streaming service)，IP多媒体系统的多媒体电话服务(multimedia telephony service for IMS，MTSI)，单纯的信号质量并不能体现用户在使用这些业务时的用户体验，为使运营商更好的了解用户的体验情况，从而更好的优化网络以更准确的提高用户的体验，目前可以通过体验质量(quality of experience,QoE)测量实现，该测量也可称为应用层测量。
目前应用层测量的基本流程如下：接入网设备从核心网设备或管理设备获取应用层测量配置信息，并将该应用层测量配置信息发送给终端设备的接入层，终端设备的接入层将该应用层测量配置信息发送给终端设备的接入层的上层，终端设备的接入层的上层接收该应用层测量配置信息，基于该配置信息进行测量，并将应用层测量结果发送给终端设备的接入层，终端设备的接入层将该应用层测量结果发送给接入网设备，接入网设备将该应用层测量结果发送给测量收集实体(measurement collector entity，MCE)设备。测量收集实体也可以称为跟踪收集实体(trace collector entity，TCE)。另外，终端设备的接入层的上层还可以上报一些接入网设备可见的测量指标。接入网设备可以根据终端设备上报的接入网设备可见的测量指标进行优化无线资源，比如当某个测量指标测量结果并不理想时，接入网设备可以给该终端设备分配更多的无线资源，或者提高该终端设备的调度优先级等。接入网设备可见的测量指标可以是应用层测量结果中的一部分测量指标，也可能是根据应用层测量结果中的一部分测量指标获得的另外一个测量结果。
上述管理设备还可以称为操作、管理和维护(operation administration and maintenance，OAM)设备、域管理(domain manager)设备，或元素管理(element manager)设备。
此外，为了提高网络优化的准确性和效率，在上述现有应用层测量方案的基础上，目前还提出了针对网络切片(slice)进行的应用层测量方案。
图3示出了针对网络切片进行的应用层测量方法300，如图3所示，S301、核心 网设备或管理设备向接入网设备发送应用层测量配置信息时携带有网络切片范围(slice scope)和业务类型(service type)(业务类型也可以称为服务类型)，该网络切片范围可以包括至少一个网络切片标识(slice ID)。网络切片标识例如可以是单网络切换选择支撑信息(single network slice selection assistance information，S-NSSAI。S302、接入网设备可以根据该网络切片标识与PDU会话标识之间的对应关系，获得上述网络切片标识对应的至少一个PDU会话标识，在业务建立过程中，核心网设备会把PDU会话标识和网络切片标识之间的对应关系发送给接入网设备。S303、接入网设备向终端设备下发上述应用层测量配置、上述至少一个PDU会话标识和业务类型。S304、终端设备可以基于上述应用层测量配置，以及上述至少一个PDU会话标识和业务类型进行测量。S305、上述终端设备向接入网设备上报应用层测量结果时，携带该应用层测量结果对应的PDU会话标识。S306、接入网设备可以根据该应用层测量结果和其对应的PDU会话标识，进行网络优化。此外，接入网设备还可以将该PDU会话标识对应的网络切片标识和应用层测量结果发送给MCE设备。但是，由于网络切片标识与PDU会话标识之间并不是一一对应的，比如一个PDU会话标识对应一个网络切片标识，但一个网络切片标识可能对应多个PDU会话标识，所以上述接入网设备可以根据网络切片标识与PDU会话标识之间对应关系，获得上述应用层测量配置信息携带的网络切片标识对应的全部PDU会话标识，又由于不同的业务类型又可能对应相同的网络切片标识，且接入网设备并不知道每个PDU会话标识对应的业务类型，所以可能导致获得的上述PDU会话标识比实际上述网络切片在本次任务中对应的PDU会话标识更多，即在上述接入网设备将上述应用层测量配置信息和上述网络切片标识对应的全部PDU会话标识发送给终端设备，因为，终端设备获得的PDU会话标识的范围更大，所以不符合网络侧的原始需求。
图4示出了又一种针对网络切片进行的应用层测量方法400，如图4所示，S401、接入网设备或管理设备向接入网设备发送应用层测量配置时携带有网络切片范围和业务类型，该网络切片范围可以包括至少一个网络切片标识。S402、上述接入网设备将上述应用层测量配置、网络切片范围和业务类型，发送给终端设备。S403、终端设备可以基于上述应用层测量配置，网络切片范围和业务类型进行应用层测量。S404、终端设备向接入网设备发送应用层测量结果，以及该应用层测量结果对应的网络切片标识。S405、接入网设备可以基于该应用层测量结果，以及对应的网络切片标识进行网络优化。此外接入网设备还可以将收到的上述应用层测量结果和对应的网络切片标识发送给MCE设备。但是，由于网络切片标识与PDU会话标识之间并不是一一对应的，接入网设备从终端设备收到的应用层测量结果、网络切片标识之后，接入网设备并不知道该应用层测量结果对应哪一个PDU会话标识，导致接入网设备只能针对该应用层测量结果对应的网络切片标识对应的所有PDU会话进行优化，导致接入网设备优化范围扩大，即无法准确执行网络优化，进而降低优化效率。
有鉴于此，本申请提出了一种网络优化方法，在终端设备向接入网设备发送应用层测量结果的同时，还将该应用层测量结果对应的PDU会话标识发送给接入网设备，使得该接入网设备在获得上述应用层测量结果的同时，获得该应用层测量结果对应的PDU会话，进而接入网设备可以针对该PDU会话的无线资源配置或调度进行优化， 此外，终端设备还可以向上述接入网设备发送PDU会话标识的同时，还发送该PDU会话标识对应QoS流标识，使接入网设备可以根据该QoS流，进而使接入网设备可以针对该PDU会话的对应的QoS流的无线资源配置或调度进行优化。进一步的，接入网设备还可以对该QoS流对应的数据无线承载(data radio bearer,DRB)的无线资源配置或调度进行优化)，有利于提高网络优化的准确性和效率，进而提高业务的性能。
为了使本申请的目的、技术方案更加清楚直观，下面将结合附图及实施例，对本申请实施例通过的网络优化方法和通信装置进行详细说明。应理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。

第三，“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中的至少一项(个)，可以表示：a，或b，或c，或a和b，或a和c，或b和c，或a、b和c，其中a，b，c可以是单个，也可以是多个。

在一种可能的实现方式中，应用层测量配置信息可以以容器(container)的形式(例如以字节串的形式)发送给终端设备。终端设备的接入层不可以感知容器中的信息，或容器中的信息对终端设备的接入层不可见，或对于终端设备的接入层而言，容器中的信息只是一些字节串，终端设备的接入层无需感知这些字节串的具体含义。例如应用层测量配置信息对应的容器携带的是以可延伸标记式语音(extensible markup language，XML)格式配置的信息。
在一种可能的实现方式中，应用层测量配置信息还可以以非容器的形式发送给终端设备，即为终端设备的接入层可以感知或可见的形式(比如信元的形式)。

可选地，核心网设备或者管理设备也可以通过容器的形式将应用层测量配置信息发送给接入网设备，接入网设备可以不解析容器中的内容(即使接入网设备有能力解析)，直接将容器转发给终端设备，或者也可以通过接入网设备可以感知或可见的形式发送上述应用层配置信息至接入网设备。
可选地，上述业务类型可以包括下列类型中的至少一个：多媒体电话业务类型、流媒体业务类型、多媒体广播和组播业务类型、虚拟现实业务类型、或扩展现实业务类型等。

可选地，该测量指标可以包括平均吞吐量指标、初始播放时延指标、缓冲级别指标、播放时延指标，恶化持续时间指标、连续丢包数指标、抖动持续时间指标、失步持续时间指标、往返时延指标、平均码率指标、类比质量视角切换时延指标、或卡顿情况指标、播放列表指标等中的至少一个。可选地，该测量指标的取值可以是一个具体的数值，也可能是一个范围(比如好，中，差中的一个)。这些指标的定义可以参考3GPP协议中的定义。
可选地，该测量指标还可以是以上平均吞吐量指标、初始播放时延指标、缓冲级别指标、播放时延指标，恶化持续时间指标、连续丢包数指标、抖动持续时间指标、失步持续时间指标、往返时延指标、平均码率指标、类比质量视角切换时延指标、或卡顿情况指标等中的多个指标的一个综合测量指标，比如按照某种规则会公式综合以上多个指标获得一个综合指标。该综合测量指标的取值可以是一个具体的数值，也可能是一个范围(比如好，中，差中的一个)。
示例性地，终端设备的接入层可以通过该终端设备的接入层与该终端设备的接入层的上层之间的口令命令(attention command)向终端设备的接入层的上层发送上述第一信息，终端设备的接入层的上层可以按照上述第一信息进行应用层测量，并获得应用层测量结果。
可选地，终端设备的接入层的上层可以按照应用层测量配置信息进行周期性的测量并获得应用层测量结果，或者在应用层测量配置信息在业务测量结束之后才产生对应的应用层测量结果。
S503、终端设备向上述接入网设备发送第二信息，对应地，接入网设备接收来自上述终端设备的第二信息。
可选地，上述第二信息包括对应于上述第一信息的应用层测量结果和该应用层测量结果对应的标识信息，该标识信息可以包括协议数据单元PDU会话标识。
示例性地，终端设备的接入层的上层在获得应用层测量结果时，产生第二信息，且该终端设备的接入层的上层通过该接入层与该接入层的上层之间的口令命令向终端设备的接入层发送上述第二信息，终端设备的接入层可以向接入网设备发送该第二信 息。
可选地，若终端设备以透明的容器的形式收到的应用层测量配置信息，则该应用层测量结果可以是终端设备的接入层以容器的形式发送给接入网设备，此时接入网设备不能感知或可见应用层测量结果(即使接入网设备有能力解析)。例如应用层测量结果对应的容器对应一些字节串，且这些字节串携带的是以XML格式携带的信息且这些信息是经过压缩之后形成了这些字节串。
可选地，若终端设备是以非容器的方式收到的应用层测量配置信息，则应用层测量结果可以是终端设备的接入层以非容器的形式发送给接入网设备，即接入网设备可以感知或可见的形式(比如信元的形式)。
可选地，若终端设备是以非容器的方式收到的应用层测量配置信息，则应用层测量结果可以是终端设备的接入层以容器的形式发送给接入网设备，但接入网设备可以感知或可见或可解析该容器中的内容。例如，应用层测量结果携带的是以XML格式的信息，接入网设备可以解析这些XML格式的信息，从而感知或可见或解析这些应用层测量结果。
可选地，应用层测量结果包括两部分，一部分是以容器的方式收到的应用层测量配置信息对应的测量结果，另外一部分是以非容器的方式收到的应用层测量配置信息对应的测量结果或者是终端设备上报协议中规定的接入网设备可以感知或可见的测量指标对应的测量结果。
可选地，应用层测量结果是终端设备上报协议中规定的接入网设备可以感知或可见的测量指标对应的测量结果。
可选地，上述标识信息还可以包括网络切片标识。接入网设备根据网络切片标识能获知该应用层测量结果对应的网络切片标识。网络切片标识可能在应用层测量结果中(即应用层测量结果中包括网络切片标识)，也可能在应用层结果之外(即应用层测量结果中不包括网络切片标识)。接入网设备收到应用层测量结果之后，接入网设备向测量收集实体发送应用层测量结果时，还发送该网络切片标识(可能在应用层测量结果之内或之外)。
应理解，在接入网设备获得上述第二信息后，该接入网设备还可以基于该第二信息，对上述PDU会话对应的无线资源配置进行优化。
在本申请实施例中，终端设备向接入网设备上报应用层测量结果时，同时还上报该应用层测量结果对应的PDU会话标识，对应的，接入网设备可以通过上述第二信息获知上述应用层测量结果及对应的PDU会话标识，并可以通过该应用层测量结果和该应用层测量结果对应的PDU会话标识，准确的定位该应用层测量结果对应的业务，进而接入网设备可以仅针对该业务进行配置或调度优化，因此本申请在准确定位测量业务的情况下，提高了网络优化的效率和准确性，进而提高该上述业务的性能。
可选地，上述第一信息也可以不包括网络切片范围信息，即不限定进行应用层测量的网络切片范围。
可选地，上述标识信息还可以包括上述PDU会话标识对应的至少一个服务质量QoS流标识；且在接入网设备对该PDU会话对应的无线资源配置进行优化之前，接入网设备还可以确定与上述至少一个QoS流标识对应的至少一个数据无线承载DRB；且 该接入网设备可以对上述至少一个DRB的配置进行优化。
作为一个可选的实施例，当接入网设备包括CU和DU时，接入网设备的CU收到上述第二信息时，并可以将该第二信息发送给接入网设备的DU，从而DU可以基于该第二信息，获知该应用层测量结果是对应哪些PDU会话，或者哪些PDU会话和QoS流，从而接入网设备的DU可以基于上述应用层测量结果对与其对应的上述PDU会话，或者与其对应的上述QoS流对应的DRB的配置或调度进行优化。
在一种可能的实现方式中，接入网设备的CU收到上述第二信息时，可以将该第二信息中的应用层测量结果和该应用层测量结果对应的QoS流对应的DRB标识发送给接入网设备的DU，从而DU可以基于该应用层测量结果对与上述QoS流对应的DRB的配置或调度进行优化。
在一种可能的实现方式中接入网设备的CU收到上述第二信息时，可以根据第二信息中的应用层测量结果和终端设备上报的与其他QoS流对应的应用层测量结果获得一个合并的应用层测量结果，接入网设备的CU把该合并的应用层测量结果和该合并的应用层测量结果对应的DRB标识发送给接入网设备的DU，从而DU可以基于该合并的应用层测量结果对所述DRB的配置或调度进行优化，其中第二信息中的应用层测量结果对应的QoS流和上述其他QoS流都是映射在上述DRB中。
示例性地，当接入网设备包括CU和DU时，接入网设备的CU收到上述第二信息时，由接入网设备的CU根据第二信息更新终端设备的无线配置信息，接入网设备的CU向接入网设备的DU发送更新的无线配置信息(比如更新之后的QoS流与DRB的映射关系，或者各个QoS流的相关QoS参数配置)。当接入网设备的CU包括CU-CP和CU-UP时，接入网设备的CU-CP向接入网设备的CU-UP发送的无线配置信息。
应理解，接入网设备还可以向MCE发送上述PDU会话标识，或上述DRB标识，从而MCE可以根据PDU会话或PDU会话对应的DRB标识找到该应用层测量结果对应的终端设备的接入层的测量结果。
示例性地，在接入网设备包括CU和DU的情况下，在接入网设备收到上述第二信息后，接入网设备的CU可以向DU发送消息，该消息用于请求对方(即DU)向MCE发送上述应用层测量结果对应的PDU会话对应的接入层的测量结果(例如时延测量结果等)，或者上述应用层测量结果对应的PDU会话对应的DRB的接入层的测量结果，或者上述应用层测量结果对应的QoS流对应的DRB的接入层的测量结果。若上述接入网设备的CU还包括CU-CP和CU-UP，则在接入网设备收到上述第二信息后，接入网设备也可以通过CU-CP向CU-UP发送消息，该消息用于请求对方(即CU-UP)向MCE发送上述应用层测量结果对应的PDU会话对应的接入层的测量结果(例如时延测量结果等)，或者上述应用层测量结果对应的PDU会话对应的DRB的接入层的测量结果，或者上述应用层测量结果对应的QoS流对应的DRB的接入层的测量结果。
可选地，接入网设备在向MCE发送上述应用层测量结果和与其对应的PDU会话标识或者对应的DRB标识时，接入网设备还可以携带时间信息，该时间信息指示接入网设备发送或接收应用层测量结果的时刻信息，从而MCE可以上述根据时间信息能获得对应时刻的终端设备的接入层的测量结果。
在本申请实施例中，接入网设备除了通过上述第二信息获知上述应用层测量结果 及对应的PDU会话标识之外，还可以获得该应用层测量结果是对应哪些PDU会话中的哪些QoS流，进而接入网设备可以根据该QoS流获得对应的DRB，并可以基于上述应用层测量结果对上述QoS流或上述QoS流对应的DRB的配置或调度进行优化，在精准定位测量业务的同时，更加细粒度的定位该业务，进一步提高网络优化的准确性和效率。
应理解，由于上述终端设备的移动性，上述发送第一信息的接入网设备和上述接收第二信息的接入网设备可能为同一个接入网设备，也可能为不同的接入网设备。
在图2所示的系统架构200中，若接入网设备203发送上述第一信息，接入网设备204接收上述第二信息，则当终端设备202接收上述第一信息后，若其未发生移动，或者移动范围较小，仍然处于上述发送第一信息的接入网设备203的范围内，并在该范围内发送第二信息，则可以确定上述发送第一信息的接入网设备203和上述接收第二信息的接入网设备204可以为同一个接入网设备，否则，可以确定上述发送第一信息的接入网设备203和上述接收第二信息的接入网设备204为不同接入网设备。
可选地，当应用层测量结果对应的PDU会话标识或QoS流标识对应的业务是终端设备与至少两个不同的接入网设备中进行传输，则可以分为两种不用的应用场景。
在一种可能的应用场景中，在多空口双连接(multi-radio dual connectivity，MR-DC)场景或多空口多连接(multi-raido multi connectivity)场景中，如图2所示，在该场景下，终端设备202可以连接至少两个接入网设备。本实施例以两个接入网设备为例，即接入网设备203和接入网设备204，若从终端设备收到应用层测量结果的是接入网设备203，则接入网设备203收到该应用层测量结果之后，可以将该应用层测量结果发送给另外一个接入网设备204，且接入网设备203可以通知接入网设备204该应用层测量结果是对应哪一个PDU会话或QoS流，即会将应用层测量结果对应的PDU会话标识和QoS流标识发送给上述接入网设备204，在这种应用场景下，接入网设备204也可以根据该应用层测量结果对上述QoS流或上述QoS流对应的DRB的配置或调度进行优化。
在另一种可能的应用场景中，在上述接入网设备203或上述接入网设备204包括CU/DU的场景中，本申请实施例以上述接入网设备203为例，在该场景下，接入网设备203接收应用层测量结果，且该接入网设备203对应的CU会向接入网设备203的DU发送上述应用层测量结果，接入网设备203向接入网设备204发送上述应用层测量结果。进一步的，接入网设备204对应的CU会向接入网设备204的DU发送从接入网设备接收到的上述应用层测量结果。且接入网设备203的CU可以通知接入网设备203的DU该应用层测量结果是对应哪一个PDU会话或QoS流或DRB，接入网设备204的CU可以通知接入网设备204的DU该应用层测量结果是对应哪一个PDU会话、QoS流或DRB，即接入网设备203的CU会将上述应用层测量结果对应的PDU会话标识、QoS流标识或DRB标识发送给上述接入网设备203的DU，接入网设备204的CU会将上述应用层测量结果对应的PDU会话标识、QoS流标识或DRB标识发送给上述接入网设备204的DU，从而，接入网设备203的DU和接入网设备204的DU根据该应用层测量结果对上述QoS流或上述QoS流对应的DRB的配置或调度进行优化。
可选地，接入网设备203对应的CU向接入网设备203的DU发送的应用层测量结果和接入网设备203向接入网设备204发送的应用层测量结果可以相同，也可以不同。
示例性地，对于上述发送的应用层测量结果相同的情况，发送的应用层测量结果都为从终端设备收到的应用层测量结果。可选地，发送上述应用层测量结果时还携带指示信息，该指示信息指示该应用层测量结果为分裂PDU会话或分裂承载(split bearer)对应的应用层测量结果。可选地，该指示信息还可以指示分裂承载(split bearer)采用了复制，即该分裂承载(split bearer在上述两个接入网设备中发送的内容相同。这种应用场景下，接入网设备203可以把从终端设备202侧接收的应用层测量结果转发给其他实体，有利于简化上述接入网设备203的处理复杂度。另外，在上述分裂承载(split bearer)采用了复制的情况下，由于终端设备202与接入网设备203和接入网设备204传输的内容是相同的，相当于上述两个接入网设备是相互独立为终端设备提供服务，所以发送相同的应用层测量结果更有利于上述两个接入网设备分别进行配置或调度优化。
示例性地，对于上述发送的应用层测量结果不相同的情况，对于吞吐率、吞吐量或缓冲级别而言，接入网设备203可以按照接入网设备203统计的分别通过接入网设备203和终端设备202之间，接入网设备204与终端设备202之间进行数据传输对应的历史吞吐率、吞吐量把收到的应用层测量结果中的吞吐率、吞吐量或缓冲级别分解到上述两个接入网设备中。例如，接入网设备203统计通过接入网设备203与终端设备202之间进行数据传输对应的历史吞吐率或吞吐量为A,统计通过接入网设备204与终端设备之间进行数据传输对应的历史吞吐率或吞吐量为B,接入网设备203从终端设备202收到的应用层测量结果中的吞吐率或吞吐量或缓冲级别为C。则接入网设备203的CU向接入网设备203的DU发送的应用层测量结果中的吞吐率或吞吐量或缓冲级别可以为：C*A/(A+B)，接入网设备203向接入网设备204发送的应用层测量结果中的吞吐率、吞吐量或缓冲级别可以为：C*B/(A+B)，在该种情况下，可以适用于上述分裂承载(split bearer)采用了非复制，即由于终端设备202与接入网设备203之间的传输内容与终端设备202和接入网设备204之间传输的内容是不相同的，相当于一部分数据通过接入网设备203与终端设备202进行传输，另外一部分数据通过接入网设备204与终端设备202进行传输，而应用层测量结果反映的是通过接入网设备203与终端设备202，以及接入网设备204与终端设备202进行传输的总体结果。所以若接入网络设备根据同一个应用层测量结果进行配置或调度优化，则会导致过优化，导致无线资源的浪费。本实施例通过接入网设备203把从终端设备202收到的应用层测量结果分解到各个接入网设备，从而可以避免该无线资源的浪费。
应理解，在上述两个应用场景中，接入网设备除可以通过上述S501～S503获得上述应用层测量结果，以及与其对应的标识信息之外，还可以采用其他方法获得应用层测量结果及与其对应的标识信息，本申请对此不作限定。
作为一个可选的实施例，上述终端设备还可以通过容器的形式发送上述第二信息；所以在接入网设备接收来自上述终端设备的第二信息之后，该接入网设备需要先解码上述第二信息，获得上述应用层测量结果和该应用层测量结果对应的标识信息，并可 以基于该标识信息精准定位被测业务，实现高效网络优化。
可选地，上述终端设备还可以通过容器的形式仅发送上述第二信息中的应用层测量结果，以非容器的形式发送上述第二信息中的其他信息，在接入网设备接收来自上述终端设备的第二信息之后，该接入网设备需要先解码上述第二信息中的应用层测量结果，获得上述应用层测量结果中的测量指标，并可以第二信息中标识信息精准定位被测业务，实现高效网络优化。

示例性地，若上述第一信息包括应用层测量配置信息、网络切片范围信息为网络切片1和业务类型1，则终端设备的接入层可以将从上述接入网设备接收到的第一信息发送给终端设备的接入层的上层，该终端设备的接入层的上层可以根据上述第一信息中的网络切片范围，确定此次测量任务在网络切片1上执行，且可以根据业务类型1选择在该网络切片1中业务类型为业务类型1的业务进行应用层测量，且将该应用层测量结果发送给终端设备的接入层。
除接入网设备接收来自终端设备的PDU会话标识或PDU会话标识和其对应的QoS流标识进行网络优化之外，本申请实施例还提供了另一种网络优化的方法，接入网设备接收来自终端设备的应用层测量结果、该应用层测量结果对应的网络切片标识，但不同的是在本申请实施例中接入网设备可以通过提前收到的业务类型和PDU会话标识之间的对应关系，自身确定与上述应用层测量结果对应的PDU会话标识，并可以对该PDU会话对应的无线资源配置进行优化。或者，接入网设备还可以通过提前收到的业务类型、PDU会话标识，以及该PDU会话对应的QoS流三者之间的对应关系，确定与上述应用层测量结果对应的PDU会话标识和对应的QoS流，并在基于该QoS流获得对应的DRB的情况下，接入网设备还可以对上述PDU会话对应的DRB配置进行优化，缩小了优化范围，有利于提高优化效率和准确性，进而提高业务的性能。

S604、接入网设备基于第一对应关系和第二对应关系，确定与上述网络切片标识和上述业务类型信息对应的至少一个协议数据单元PDU会话标识。
应理解，上述第一对应关系指示网络切片标识和PDU会话标识之间的对应关系，上述第二对应关系指示业务类型、PDU会话标识之间的对应关系。
同上述实施例类似，接入网设备还可以基于上述第三信息，对上述至少一个PDU会话对应的无线资源配置进行优化，以及，由于终端设备的移动性，上述发送第一信息的接入网设备和上述接收第三信息的接入网设备可能为同一个接入网设备，也可能为不同的接入网设备，且在上述发送第一信息的接入网设备和上述接收第三信息的接入网设备为两个不同的接入网设备的情况下，本申请实施例也可以适用于上述两种不同的应用场景中，为避免重复此处不再做赘述。
在本申请实施例中，接入网设备可以根据终端设备上报的应用层测量结果对应的网络切片标识以及业务类型与PDU会话标识之间的对应关系，获得该应用层测量结果对应的至少一个PDU会话标识，在缩小该应用层测量结果对应的业务前提下，缩小了网络优化范围，提高网络优化效率，进而有效提高业务的性能。
作为一个可选的实施例，上述业务类型信息包括上述应用层测量结果对应的业务类型，或者与上述应用层测量结果对应的配置标识。上述接入网设备基于第一对应关系和第二对应关系，确定与上述网络切片标识和上述业务类型信息对应的至少一个PDU会话，包括：该接入网设备基于上述第一对应关系和上述网络切片标识，确定至少一个备选PDU会话标识；并基于上述业务类型或上述配置标识，确定该应用层测量结果对应的业务类型；上述接入网设备可以基于上述第二对应关系、上述至少一个备选PDU会话标识和上述应用层测量结果对应的业务类型，确定与该应用层测量结果对应的上述至少一个PDU会话标识。
应理解，上述配置标识用于指示上述应用层测量结果对应的业务类型。该配置标识可能是体验质量参考(QoE reference)或者接入网设备为终端业务的该应用层测量分配的一个标识。接入网设备可以根据配置标识获知该应用层测量结果对应的应用层测量配置，从而能获知对应的业务类型。
作为一个可选的实施例，上述第二对应关系还可以用于表示业务类型、PDU会话标识和QoS流标识之间的对应关系，在上述接入网设备基于上述第三信息，对上述至少一个PDU会话对应的无线资源配置进行优化之前，该方法还包括：接入网设备可以基于上述第二对应关系，确定上述至少一个PDU会话对应的至少一个QoS流标识，并确定与该至少一个QoS流标识对应的至少一个数据无线承载DRB，该接入网设备可以对上述至少一个PDU会话对应的上述至少一个DRB配置进行优化。
应理解，在上述接入网设备向终端设备发送第一信息之前，该接入网设备接收来自核心网设备的上述第一对应关系，该接入网设备接收来自上述核心网设备或管理设备的上述第二对应关系。
此外，本申请实施例还提供了另一种网络优化的方法，与上述实施例不同的是接入网设备可以根据网络切片标识和PDU会话标识之间的对应关系，提前确定应用层配置信息对应的PDU会话标识，或者根据网络切片标识、PDU会话标识和QoS流标识三者之间的对应关系，提前确定应用层配置信息对应的PDU会话标识和QoS流标识，并将上述确定的PDU会话标识，或者PDU会话标识和对应的QoS流标识发送终端设备，即终端设备在收到上述PDU会话标识，或者上述PDU会话标识和对应的QoS流标识之后，可以明确上述应用层测量配置对应的测量范围，且该范围相较于上述实施例更小，所以有利于提高终端设备的应用层测量效率，且在终端设备向接入网设备发 送应用层测量结果的同时，还发送了该应用层测量结果对应的PDU会话标识，或者至PDU会话标识和与其对应QoS流标识，使接入网设备可以精准定位业务，进而有利于提高网络优化效率和准确性。
