体验质量(quality of experience，QoE)是一种性能指标，用于评价用户对设备、网络、系统、应用或业务的质量和性能(包括有效性和可用性等方面)的综合主观感受，也就是从业务应用的舒适度来定义的。对体验质量进行测量被称为QoE测量(也被称为应用层测量)。应用层测量还可以指终端设备上报设备、应用或业务的质量和性能。运营商通过收集QoE测量结果(也被称为应用层测量结果)来获知用户体验的状况，进而更好的优化网络以提高用户体验。

具体实施方式
下面结合附图，对本发明提供的实施例做详细说明。本发明实施例描述的网络架构以及业务场景是为了更加清楚的说明本发明实施例的技术方案，并不构成对于本发明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，本发明实施例提供的技术方案对于类似的技术问题，同样适用。
图1示出了本申请的一种可能的系统网络示意图。如图1所示，至少一个终端10与无线接入网(Radio access network,RAN)进行通信。所述RAN至少包括两个基站：基站20和基站30，图中只示出两个基站和一个用户设备UE。所述RAN与核心网络(core network,CN)相连。所述核心网络包括一个或多个核心网设备。可选的，所述CN可以耦合到一个或 者更多的外部网络(External Network)，例如英特网Internet，公共交换电话网(public switched telephone network，PSTN)等。其中，UE在移动过程中，与无线接入网的连接可以由基站20切换至基站30，此时，基站20可以称为源基站，基站30可以称为目标基站，UE可以通过空中接口(例如Uu接口)与基站通信。
在长期演进(long term evolution，LTE)和新无线(new radio，NR)中，UE和基站/接入和移动性管理功能(access and mobility management function，AMF)实体通过空口进行通信。为了更好地对数据进行处理，网络协议定义了若干协议栈，每个栈的功能各不相同，例如，如图2所示。其中，非接入(non-access stratum,NAS)层是UE和AMF之间的信令通道，具体过程可以是UE向基站发送NAS消息，基站将NAS消息透传给AMF，基站在透传的过程中不对NAS消息进行解析。NAS层主要负责一些管理功能，如公共陆地移动网络(public land mobile network,PLMN)选择，手动选择，接入控制，注册，签约信息等，具体的过程可以和别的协议层，例如接入(access stratum，AS)层协同进行。
AS层是指除NAS层之外的协议层，可以包括无线资源控制(radio resource control，RRC)、分组数据汇聚协议(packet data convergence protocol，PDCP)、无线链路控制(radio link control，RLC)、媒体接入控制(medium access control，MAC)、物理层(physical layer，PHY)，AS层主要负责切换，加密，数据重传，排序，发送等功能。
为便于理解下面对本申请中涉及到的一些名词做些说明。
本申请中，名词“网络”和“系统”经常交替使用。但本领域的技术人员可以理解其含义。本申请中所描述的通信装置是指的通信系统中的网元，例如终端、基站、核心网设备。
终端，有时也叫用户设备(User Equipment，UE)。UE是一种具有通信功能的终端设备，也可以称为终端，可以包括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等。例如，具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：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 internet device，MID)、可穿戴设备，虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)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。
接入网设备，是指将终端接入到无线网络的无线接入网(radio access network，RAN)节点(或设备)，通常包括基站。目前，一些RAN节点的举例为：继续演进的节点B(gNB)、传输接收点(transmission reception point，TRP)、演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，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home Node B，HNB)、基带单元(base band unit，BBU)，或无线保真(wireless fidelity，Wifi)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)节点、或分布单元(distributed unit，DU)节点、或包括CU节点和DU节点的RAN设备。其中包括CU节点和DU节点的RAN设备将基站的协议层拆分开，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。CU，DU只是一个名称示例，实现相同或类似功能的设备或实体还可以有其他名称，本申请对此不做限定。
核心网设备，是指为终端提供业务支持的核心网(core network，CN)中的设备。目前，一些核心网设备的举例为：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，所述AMF实体可以负责终端的接入管理和移动性管理；所述SMF实体可以负责会话管理，如用户的会话建立等；所述UPF实体可以是用户面的功能实体，主要负责连接外部网络。
网络中还可以包括操作、管理和维护(operation，administration and maintenance，OAM)、元素管理(element manager，EM)、跟踪收集实体(tracking area code，TCE)或测量收集实体(measurement collector entity，MCE)等网元或实体。
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，在描述具体网元或实体时有时会略去“实体”“网元”“功能实体”等，例如AMF实体简称为AMF，UPF实体简称为UPF。在未来通信系统，如6G中，上述网元还可以有其它的名称，本申请不做限定。
为了便于理解本申请的实施例，下文先对应用层测量的主要流程进行举例说明。
对于一些流类业务或者语音业务而言，比如流服务(streaming service)、语音服务、IP多媒体系统的多媒体电话服务(multimedia telephony service for IMS，MTSI)、虚拟现实技术(virtual reality，VR)业务以及增强现实(augmented reality，AR)业务、多播广播业务(multicast and broadcast service，MBS)等,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，运营商想知道用户的体验是如何，从而更好的优化网络以提高用户的体验。这类测量收集称为QoE测量收集，也可称为应用层测量收集。
基站从CN或OAM或EM收到这些测量相关的配置信息。这些配置信息中一部分可以以一种透明的容器(container)的方式发给基站，基站把这些配置通过RRC消息发送给UE。UE的RRC层从上层(例如应用层)收到应用层测量结果之后，把这些测量结果发送给基站。测量结果可以以一种透明容器的封装形式给基站。基站从CN或OAM或EM接收的信息除了以上的测量的配置信息之后，还可能包括QOE测量的其他信息，比如QOE测量的区域范围，QOE测量的业务类型等。基站可以通过RRC重配消息把QoE测量配置发送给UE。基站可以为UE配置一个信令承载来传输QoE测量结果。UE的测量结果可通过该信令承载来发送。给UE下发QoE测量相关的配置信息的基站，可能和接收UE发送QoE测量结果的基站并不是同一个基站。
参考图3，QoE测量的主要流程如下：
步骤301，RAN从CN或OAM获取QoE测量配置信息。
对于基于信令的QoE测量，RAN从CN中获取QoE测量配置信息。
QOE测量配置信息包含一个QoE测量配置容器(QoE measurement configuration container)，业务类型(service type)等。此外，该QOE测量配置信息还包括QoE测量收集(QoE measurement collection，QMC)的区域范围。其中，QMC的区域范围包括：小区标识列表(Cell ID List)以及QMC的跟踪区域列表(tracking area list，TA List)、跟踪区域标识列表(tracking area identity list，TAI List)等。QoE测量配置容器中携带的是给UE的QoE测量配置。例如，QoE测量配置容器中包括了指示UE上报哪些测量值，上报间隔。上报间隔是指终端设备周期性上报测量结果或者在业务结束之后才上报测量结果。QoE测量配置容器中还可能包括测量的开始时间和持续时间，以及测量的区域范围。QoE测量配置容器可以是通过可延伸标记式语言(Extensible Markup Language，XML)的形式来携带以上信息。由于，接入网设备在获得封装了QoE测量配置的container之后，并不会解包该container，因此，将这种封装在container中的接入网设备不主动解包识别的QoE测量配置称为接入网设备不可识别的QoE测量配置。此外，与该接入网设备不可识别的QoE测量配置对应的QoE测量结果也是接入网设备不可识别的QoE测量结果，并且，该接入网设备不可识别的QoE测量结果也是通过封装在container中传输至接入网设备，因此，接入网设备不可识别的QoE测量结果常被称为QoE测量报告容器(QoE measurement report container)。
CN通知的是针对某个特定UE的QOE测量配置信息，比如通过RAN与CN之间针对某个UE的接口消息发送该QOE测量配置信息。
对于基于管理的QoE测量，RAN从OAM或EM中获取QoE测量配置信息。OAM或EM通知的不是针对某个特定UE的QOE测量配置信息。
另外，CN或OAM还可能通知基站，发送给UE的应用层测量配置包括让UE上报如下应用层指标的指示(基站可以感知或可以识别UE会对如下应用层指标进行测量)，该应用层的指标可能是如下指标：
平均吞吐量：该指标指示的是一个测量间隔内，UE的应用层接收的总比特数。如对于流媒体业务。初始播放时延：该指标指示的是在流媒体开始呈现的初始播放时延。比如具体可以定义为从获取媒体的第一段的时刻到从客户端缓冲区中提取流媒体的时刻。例如可以参考3GPP协议TS 26.247-g30中的定义。
缓冲级别：该指标指示的是从当前播放时刻开始，媒体数据还可以播放的持续时间。播放时延：该指标指示的是流媒体启动的播放时延。比如具体可以定义为从由超文本传送协议传输的动态自适应流媒体(Dynamic Adaptive Streaming over HTTP，DASH)播放器收到一个播放/回退/开始触发到媒体播放的时延。例如可以参考3GPP协议TS 26.247-g30中的定义。
恶化持续时间：该指标指示的在恶化之前的上一个质量好帧对应的尼泊尔时间(Nepal Time,NPT)到后续第一个质量好帧对应的尼泊尔时间之间的间隔。一个质量好帧时指一个被完整接受的帧，且该帧对应的图片中所有部分包含了正确的内容或者该帧时一个新帧(即不依赖于之前任何已经解码的帧)或只依赖之前已经解码的质量好帧。连续的丢包数：该指标指示的是连续丢失的实时传输协议(Real-time Transport Protocol,RTP)报文数目。例如可以参考3GPP协议TS26.114-g20中的定义。
抖动持续时间：抖动是指一个帧的实际播放时刻和期望的播放时刻之间的差别超过一个门限。一个帧的期望的播放时刻是指上一个播放帧的播放时刻加上(当前帧的尼泊尔时间和上一个播放帧的尼泊尔时间之间的差别)。失步持续时间：失步是指一个值A和一个值B之间的绝对时间差别超过一定门限。这里的值A时指一个视频流的上一个播放帧的播放时刻和语音流的上一个播放帧的播放时刻之间的差别。这里的值B是指该视频流的上一个播放帧的期望的播放时刻和该语音流的上一个播放帧的期望的播放时刻之间的差别。例如可以参考3GPP协议TS 26.114-g20中的定义。
往返时延：该指标指示的是RTP级别的往返时间，并加上在客户端中由于缓冲和其他处理导致的额外的两方向的时延(RTP级别->扬声器->话筒->RTP级别)。平均码率:该指标指示的是在测量周期内编码有效的媒体信息的比特率。例如可以参考3GPP协议TS 26.114-g20中的定义。
类比质量视角切换时延(comparable quality viewport switching latency)：该指标上报当视角移动导致质量下降时的时延和质量相关因素。质量相关因素包括质量排序值(quality ranking value)、分辨率。卡顿情况：该指标指示的是在视频流播放过程中是否发生了卡顿，或者卡顿发生的时间长度。例如可以参考3GPP协议TS 26.118-g02中的定义。
本申请中，感知是指接入网设备可以解读接收到的信息，“感知”还可以替换为可见、获知、检测等，不作限定。
步骤302，RAN把应用层测量配置发送给UE。
对于基于信令的QoE测量，RAN把应用层测量配置发送对应的UE.RAN也会根据UE是否支持QoE测量来决定是否为UE配置QoE测量。应用层测量配置包括前面的QoE测量配置容器。
对于基于管理的QoE测量，RAN根据OAM/EM发送的QoE测量配置信息以及UE是否支持对应的QoE测量以及其他一些因素选择合适的UE进行QoE测量。RAN选择完UE之后，再把应用层测量配置发送给UE.应用层测量配置包括前面的QoE测量配置容器。
RAN通过RRC消息把从CN或OAM或EM中获取的应用层测量配置发送给UE，该消息中也携带该应用层测量配置对应的业务类型。
注：现有技术中还提到RAN可以自己触发为UE配置应用层测量配置，并不限定于需要收到步骤1中的命令而触发。
除了把应用层测量配置发送给UE之外，RAN还可以向UE下发一些指示UE上报RAN感知的QoE测量结果对应的配置信息。指示UE上报RAN感知的QoE测量结果对应的配置信息用于RAN通知UE以RAN可以感知的形式(比如信息元素形式)上报一些应用层指标，这样RAN能知道对应的应用层指标测量结果，或者RAN可以通知UE上报一个应用层指标的综合分数或接入层指标的综合分数或者结合应用层指标和接入层指标得到的综合分数或者一个指示应用层指标优劣程度的指标(比如取值可以是好，中，差)(比如基站给UE下发一些阈值，UE根据应用层指标测量结果及该应用层测量指标对应的一些阈值，从而知道上报应用层指标测量结果对应的优劣程度的指标)。另外，RAN可以无需向UE下发关于RAN 感知测量结果的一些配置信息，UE在获得应用层指标之后，UE向RAN上报协议规定的且当前UE能获取到的一些应用层指标，或一个应用层指标的综合分数，或接入层指标的综合分数，或者结合应用层指标和接入层指标得到的综合分数，或者一个指示应用层优劣程度的指标。
可选的，应用层测量配置还可能不包括前面的QoE测量配置容器，比如，包括应用层测量配置对应的业务类型，以及指示UE上报RAN感知的QoE测量结果对应的配置信息。
RAN会为UE配置一个传输QoE测量结果的承载，该承载可以是信令无线承载，比如SRB4.该承载的配置信息可以和应用层测量配置在同一个RRC消息发送给UE的AS(比如UE的RRC层)，也可能通过不同的消息发送。
步骤303，UE的AS把从RAN收到的应用层测量配置发送给UE的AS的上层。
这里的UE的AS的上层可以是应用层，也可能是其他可以进行QoE测量的层。
UE的AS把应用层测量配置和业务类型发送给UE的AS的上层。
UE的AS的上层根据应用层测量配置进行QoE测量。
除了把应用层测量配置发送给AS的上层之外，UE的AS还把从RAN接收的RAN可以感知的形式上报的一些应用层指标配置发送给UE的AS的上层。
步骤304，UE的AS的上层把应用层测量结果发送给UE的AS。
UE的AS的上层按照一定的规则(比如该规则是包含在应用层测量配置中)进行上报应用层测量结果。比如UE的AS的上层周期性上报应用层测量结果。比如UE可以在一个会话结束之后才上报应用层测量结果。
当UE的AS的上层根据应用层测量配置需要上报应用层测量结果时，UE的AS的上层把应用层测量结果发送给UE的AS，同时UE的AS的上层会指示该QOE测量结果对应的业务类型。
另外，UE的AS的上层除了上报RAN不可见的应用层测量结果之外，还可以上报RAN可见的测量结果(比如以信息元素形式上报的应用层指标或者综合分数)。
步骤305，UE的AS把应用层测量结果发送给RAN。
UE的AS把应用层测量结果和对应的业务类型发送给RAN。比如在上行RRC消息中携带这些信息。应用层测量结果也是通过一种container形式发送给RAN.
注：下发应用层测量配置信息的RAN可能和接收应用层测量结果的RAN不是同一个基站(由于移动性，更换了RAN)，也可能是同一个基站.
另外，UE的AS除了上报RAN不可见的应用层测量结果之外，还可以上报RAN可见的测量结果(比如以信息元素形式上报的应用层指标或者综合分数)。
步骤306，RAN把应用层测量结果发送给TCE。
RAN把应用层测量结果发送给TCE.
另外，RAN可以根据UE上报的RAN可见的测量结果进行优化无线资源(比如当某个应用层指标测量结果并不理想时，基站可以给该UE分配更多的资源，或者提高该UE的调度优先级等)
当RAN负载比较高时，RAN可以通知UE暂停QoE测量结果上报。但UE的AS的上层仍然会继续QoE测量(已经开始的QoE测量还会继续)。对于这些UE的AS的上层还仍然会继续QoE测量的场景，由于UE的AS不会把这些结果发送给RAN，UE需要处理新产生的应用层测量结果。
针对步骤307-310，基站指示UE暂停QoE测量，UE继续存储QoE测量结果。在UE接收到基站发送的恢复QoE测量上报指示后，上报存储的QoE测量结果。
下文以5G网络为例，对本发明实施例的相关方案进行描述，但本发明的方案并不限于5G网络，例如本发明的方案还可以适用于LTE，或者后续演进网络，或者多种融合网络等，本发明实施例对此不作限定。本申请中不同实施例给出的各个名称的定义可以相互参考，不限于某一个实施例。
实施例一
本发明实施例提供了一种基于时间指示的应用层测量结果保存方案。如图4所示，包括如下步骤：
401.终端设备的RRC层接收来自于所述RRC层的上层的第一业务类型的应用层测量结果和第二业务类型的应用层测量结果。
可选的，第一业务类型和第二业务类型，还可以是第一切片(slice)和第二切片，或者第一测量配置和第二测量配置等。即本发明中第一业务类型和第二业务类型可以用第一切片(slice)和第二切片，或者第一测量配置和第二测量配置替代。
可选的，在步骤401之前，终端设备从接入网设备接收应用层测量配置以及终端设备的RRC层把应用层测量配置发送给终端设备的RRC层的上层。例如具体可参见前面图3中的描述。
可选的，在步骤401之前，终端设备的RRC层可以向终端设备的RRC层的上层发送第一能力信息，第一能力信息指示终端设备的RRC层是否支持对应用层测量结果进行分段传输(或称为是否支持对RRC消息进行分段传输)。其中终端设备的RRC层支持对应用层测量结果进行分段传输是指终端是指终端设备通过RRC消息携带应用层测量结果时，可以对该RRC消息进行分段传输，其中每一段也是通过RRC消息发送。例如，终端设备的RRC层通过RRC消息携带了一个或多个应用层测量结果之后，发现该RRC消息的大小超过PDCP层支持的PDCP SDU的最大长度，则终端设备的RRC层对该RRC消息进行分割为多段，终端设备的RRC层在用另外一个RRC消息(可以简称为新的RRC消息)来携带这些分段，携带每个分段的新的RRC消息中携带一个分段指示信息，该分段指示信息指示档期那是否为最后一个分段。当终端设备的RRC层的上层收到第一能力信息之后，就获知终端设备的RRC层是否支持对应用层测量结果进行分段传输。当终端设备的RRC层支持对应用层测量结果进行分段传输时，则终端设备的RRC层的上层就可以向终端设备的RRC层发送更大的应用层测量结果(比如超过PDCP层支持的PDCP SDU的最大长度的应用层测量结果)。终端设备的RRC层在通过RRC消息携带应用层测量结果之后，发现应用层测量结果的大小超过PDCP层支持的PDCP SDU的最大长度，则终端设备的RRC层对该RRC消息进行分段传输。当终端设备的RRC层不支持对应用层测量结果进行分段传输时，则终端设备的RRC层的上层就不能向终端设备的RRC层发送更大的应用层测量结果(比如超过PDCP层支持的PDCP SDU的最大长度的应用层测量结果)。第一能力指示信息可能只是指示终端设备的RRC层支持对应用层测量结果进行分段传输，当终端设备的RRC层没有向终端设备的RRC层的上层发送第一能力信息时，则默认终端设备的RRC层不支持对应用层测量结果进行分段传输。需要说明的是，该终端设备的RRC层向终端设备的RRC层的上层发送第一能力信息的步骤可以独立于本实施例，即可以和其他实施例或其他技术相结合。
RRC层的上层可以是应用层，也可能是其他可以进行QoE测量的层。
402.所述终端设备的RRC层接收来自于接入网设备的第一指示信息和第二指示信息，所述第一指示信息指示所述终端设备暂停第一业务类型的应用层测量结果上报，所述第二指示信息指示所述终端设备暂停第二业务类型的应用层测量结果上报。
可选的，上述第一指示信息和第二指示信息可以是同一个信息(即接入网设备通过一个指示信息来指示终端设备停止两个或多个业务类型的应用层测量结果上报)，也可以是两个信息(例如通过两条信令携带)。
本申请并不限制步骤401和步骤402的先后关系。所述终端设备的RRC层接收来自于接入网设备的第一指示信息和第二指示信息之前，终端设备的RRC层可能并没有收到第一业务类型的应用层测量结果和第二业务类型的应用层测量结果。
403.所述终端设备的RRC层接收来自于所述接入网设备的第一时间信息，所述第一时间信息指示保存第一业务类型的应用层测量结果的时长。
404.所述终端设备的RRC层接收来自于所述接入网设备的第二时间信息，所述第二时间信息指示保存第二业务类型的应用层测量结果的时长。
可选的，上述第一时间信息指示的时长，与第二时间信息指示的时长不同。网络侧可以通过设置时长来指示第一业务类型应用层测量和第二业务类型应用层测量的优先级。例如，将第一时间信息指示的时长设置为大于第二时间信息指示的时长，则表示第一业务类型应用层测量优先级高于第二业务类型应用层测量。
步骤403和步骤404可以在步骤401和402之前，比如接入网设备向终端设备发送应用层测量配置时携带所述第一时间信息和第二时间信息。
可选的，上述方法还可以包括：405.所述终端设备的RRC层启动第一定时器，所述第一定时器的时长由所述第一时间信息确定，当所述第一定时器超时时，所述UE的RRC层暂停第一业务类型的应用层测量结果存储；或者所述终端设备的RRC层丢弃所述时长外的第一业务类型的应用层测量结果。
第一定时器的时长为上述第一时间信息指示的保存第一业务类型的应用层测量结果的时长。当第一定时器超时后，对于终端设备RRC层从上层新收到的第一业务类型的应用层测量结果，RRC层会丢弃。可选的，终端设备的RRC层可以在收到第一指示信息或收到第一时间信息时启动第一定时器，也可以在存储应用层测量结果的内存空间用尽时，启动第一定时器。
或者，终端设备的RRC层仅保存最近时长收到的第一业务类型的应用层测量结果，时长为第一时间信息指示的保存第一业务类型的应用层测量结果的时长。对于超出时长的第一业务类型的应用层测量结果，终端设备的RRC层会丢弃。可选的，在存储应用层测量结果的内存空间用尽时，终端设备的RRC层才会指示仅保存最近时长收到的第一业务类型的应用层测量结果。
406.所述终端设备的RRC层启动第二定时器，所述第二定时器的时长由所述第二时间信息确定，当所述第二定时器超时时，所述UE的RRC层暂停第二业务类型的应用层测量结果存储；或者所述终端设备的RRC层丢弃所述时长外的第二业务类型的应用层测量结果。
第二定时器的时长为上述第二时间信息指示的保存第二业务类型的应用层测量结果的时长。当第二定时器超时后，对于终端设备RRC层从上层新收到的第二业务类型的应用层测量结果，RRC层会丢弃。可选的，终端设备的RRC层可以在收到第二指示信息或收到第二时间信息时启动第二定时器，也可以在存储应用层测量结果的内存空间用尽时，启动第二定时器。
或者，终端设备的RRC层仅保存最近时长收到的第二业务类型的应用层测量结果，时长为第二时间信息指示的保存第二业务类型的应用层测量结果的时长。对于超出时长的第二业务类型的应用层测量结果，终端设备的RRC层会丢弃。可选的，在存储应用层测量结果的内存空间用尽时，终端设备的RRC层才会指示仅保存最近时长收到的第二业务类型的应用层测量结果。
步骤405通常在步骤402和403之后，步骤406通常在步骤402和404之后。其他步骤之间的先后关系，本申请不做限定。
通过上述保存应用层测量结果的方案，提高了存储效率。另外，通过设置不同业务类型或切片或测量配置的优先级，使得UE优先保存高优先级的测量结果，从而在发生暂停QoE测量结果上报时，网络侧可以优先获得高优先级的业务类型或切片或测量配置的应用层测量结果，满足了运营商对不同业务类型或切片或测量配置的测量需求，利于网络优化。
实施例二
本实施例提供了一种基于内存的应用层测量结果保存方法，如图5所示，包括如下步骤：
501.终端设备的RRC层接收来自于所述RRC层的上层的第一业务类型的应用层测量结果和第二业务类型的应用层测量结果。
可选的，第一业务类型和第二业务类型，还可以是第一切片(slice)和第二切片，或者第一测量配置和第二测量配置等。
可选的，在步骤501之前，终端设备从接入网设备接收应用层测量配置以及终端设备的RRC层把应用层测量配置发送给终端设备的RRC层的上层。例如具体可参见前面图3中的描述。
可选的，在步骤501之前，终端设备的RRC层可以向终端设备的RRC层的上层发送第一能力信息。第一能力信息的描述参见图4的描述。
502.所述终端设备的RRC层接收来自于接入网设备的第一指示信息和第二指示信息，所述第一指示信息指示所述终端设备暂停第一业务类型的应用层测量结果上报，第二指示信息指示所述终端设备暂停第二业务类型的应用层测量结果上报。
可选的，上述第一指示信息和第二指示信息可以是同一个信息(即接入网设备通过一个指示信息来指示终端设备停止两个或多个业务类型的应用层测量结果上报)，也可以是两个信息(例如通过两条信令携带)。
503.所述终端设备的RRC层在第一内存空间存储第一业务类型的应用层测量结果；所述终端设备的RRC层在第二内存空间存储第二业务类型的应用层测量结果。
第一业务类型的应用层测量结果和第二业务类型的应用层测量结果，使用不同的内存空间，彼此可以独立。第一业务类型的应用层测量结果对应的内存空间已满时，不影响第二业务类型应用层测量结果的存储。上述内存空间用于存储应用层测量结果。
可选的，所述终端设备的RRC层在第一内存空间存储第一业务类型的应用层测量结果包括：所述终端设备的RRC层从RRC层的上层收到新的第一业务类型的应用层测量结果时，且当所述第一业务类型的应用层测量结果对应的第一内存空间用尽时，所述RRC层丢弃新收到的第一业务类型的应用层测量结果。
所述终端设备的RRC层在第二内存空间存储第二业务类型的应用层测量结果包括：所述终端设备的RRC层从RRC层的上层收到新的第二业务类型的应用层测量结果时，当所述第二业务类型的应用层测量结果对应的第二内存空间用尽时，所述RRC层丢弃新收到的第二业务类型的应用层测量结果。
步骤501和502不限定先后顺序。所述终端设备的RRC层接收来自于接入网设备的第一指示信息和第二指示信息之前，终端设备的RRC层可能并没有收到第一业务类型的应用层测量结果和第二业务类型的应用层测量结果。
本实施中，通过不同业务类型或切片或测量配置的内存空间独立，不同业务类型或切片或测量配置的测量结果不会相互覆盖，提供了应用层测量结果的存储灵活性及效率。
实施例三
本实施例提供了一种基于内存的应用层测量结果保存方法，如图6所示，包括如下步骤：
601.终端设备的RRC层接收来自于所述RRC层的上层的第一业务类型的应用层测量结果和第二业务类型的应用层测量结果。
可选的，第一业务类型和第二业务类型，还可以是第一切片(slice)和第二切片，或者第一测量配置和第二测量配置等。
可选的，在步骤601之前，终端设备从接入网设备接收应用层测量配置以及终端设备的RRC层把应用层测量配置发送给终端设备的RRC层的上层。例如具体可参见前面图3中的描述。
可选的，在步骤601之前，终端设备的RRC层可以向终端设备的RRC层的上层发送第一能力信息。第一能力信息的描述参见图4的描述。
602.所述终端设备的RRC层接收来自于接入网设备的第一指示信息和第二指示信息，所述第一指示信息指示所述终端设备暂停第一业务类型的应用层测量结果上报，第二指示信息指示所述终端设备暂停第二业务类型的应用层测量结果上报。
可选的，上述第一指示信息和第二指示信息可以是同一个信息(即接入网设备通过一个指示信息来指示终端设备停止两个或多个业务类型的应用层测量结果上报)，也可以是两个信息(例如通过两条信令携带)。

可选的，所述第一业务类型的应用层测量结果和第二业务类型的应用层测量结果共享用于存储应用层测量结果的内存空间。
可选的，所述终端设备在步骤603之前从接入网设备收到指示信息，指示第一业务类型的优先级以及第二业务类型的优先级，或者指示某些业务类型的优先级，如果接入网设备没有发送指示信息指示某些业务类型的优先级，则这些业务类型的优先级默认为最高或最低。
针对步骤603，一种可选的方案，所述终端设备的RRC层优先保存第一业务类型的应用层测量结果包括：
当用于存储应用层测量结果的内存空间用尽时，所述RRC层删除已保存的第二业务类型的应用层测量结果，保存新收到的第一业务类型的应用层测量结果。
针对步骤603，另一种可选的方案，所述终端设备的RRC层优先保存第一业务类型的应用层测量结果包括：
当所述用于存储应用层测量结果的内存空间用尽时，所述RRC层删除未收到结束指示的已保存的第二业务类型的应用层测量结果，保存新收到的第一业务类型的应用层测量结果。所述RRC层不删除已经收到结束指示的已保存的第二业务类型的应用层测量结果。
在内存空间用尽的情况下：对于已存储的第二业务类型的应用层测量结果，如果RRC层未收到该测量结果对应的结束指示，则在收到新的第一业务类型的应用层测量结果时，删掉未收到结束指示的第二业务类型的应用层测量结果，保存新收到的第一业务类型的应用层测量结果。如果已存储的第二业务类型的应用层测量结果，已经收到了结束指示，则在收到新的第一业务类型的应用层测量结果时，不删除该第二业务类型的应用层测量结果。如果无法删除其他的应用层测量结果，则丢弃新收到的第一业务类型的应用层测量结果。
其中UE的RRC层的上层收到应用层测量配置时，当前述业务类型对应的业务开始时，UE会启动对应的应用层测量。当UE的RRC层的上层启动应用层测量时，UE的RRC层的上层会向UE的接入层发送一个开始指示，该开始指示用于指示前述业务类型对应的某个会话对应的应用层测量开始了。该开始指示包括该应用层测量启动对应的信息。该应用层测量启动对应的信息包括如下一项：UE已经启动的应用层测量对应的业务类型、该业务类型中哪些切片(slice)的应用层测量已经启动(比如携带单网络切片选择辅助信息(single network slice selection assistance information，S-NSSAI))、记录会话指示(record session indication)。其中，记录会话指示在某个会话的整个过程中是相同的，不同的会话对应不同的记录会话指示，即UE的RRC层的上层会为不同的会话分配不同的记录会话指示。
可选的，当前述业务类型对应的业务结束时，UE会结束对应的应用层测量。当UE的RRC层的上层结束应用层测量时，UE的RRC层的上层会向UE的接入层发送一个结束指示，该结束指示用于指示前述业务类型对应的某个会话对应的应用层测量结束了。该结束指示包括该应用层测量结束对应的信息。该应用层测量结束对应的信息包括如下一项：UE已经结束的应用层测量对应的业务类型、该业务类型中哪些slice的应用层测量已经结束(比如携带S-NSSAI)、记录会话指示(record session indication)。
需要说明的是，收到结束指示的已保存的的应用层测量结果是指UE的RRC层收到该应用测量结果对应的会话对应的结束指示。由于只有获得一个会话的完整的应用层测量结果才有意义，如果删除这些收到结束指示的已保存的的应用层测量结果，则终端设备之前已经发送给接入网设备的那些对应该会话的应用层测量结果就没有意义。
步骤601和602不限定先后顺序。所述终端设备的RRC层接收来自于接入网设备的第一指示信息和第二指示信息之前，终端设备的RRC层可能并没有收到第一业务类型的应用层测量结果和第二业务类型的应用层测量结果。
本实施中，通过定义不同业务类型或切片或测量配置对应的应用层测量结果的优先级，在终端设备暂停QoE测量上报时，优先保存高优先级的应用层测量结果，满足了运营商对不同业务类型或切片或测量配置的测量需求，提供了应用层测量结果的存储灵活性及效率。同时通过只删除未收到结束指示的已保存的应用层测量结果，避免了删除那些应用层测量已经结束的会话对应的应用层测量结果，从而保证了网络侧能获得完整的应用层测量结果。
实施例四
本实施例提供了一种基于门限的应用层测量结果保存方法，如图7所示，包括如下步骤：
701.终端设备的RRC层接收来自于所述RRC层的上层的第一业务类型的应用层测量结果。
可选的，第一业务类型，还可以是第一切片(slice)，或者第一测量配置等。
可选的，在步骤701之前，终端设备从接入网设备接收应用层测量配置以及终端设备的RRC层把应用层测量配置发送给终端设备的RRC层的上层。例如具体可参见前面图3中的描述。
可选的，在步骤701之前，终端设备的RRC层可以向终端设备的RRC层的上层发送第一能力信息。第一能力信息的描述参见图4的描述。
702.所述终端设备的RRC层接收来自于网络设备的第一指示信息，所述第一指示信息指示所述终端设备暂停第一业务类型的应用层测量结果上报。
703.当所述第一业务类型的应用层测量结果对应的AS测量结果，或者所述RRC层收到的所述第一业务类型的应用层测量结果时的AS测量结果，或者所述第一业务类型的应用层测量结果对应的接入网设备可见的测量结果，满足第一门限对应的条件时，所述终端设备的RRC层保存所述第一业务类型的应用层测量结果。
可选的，当不满足上述第一门限对应的条件时，所述终端设备的RRC层不保存所述第一业务类型的应用层测量结果。
可选的，这里说的满足第一门限对应的条件可以指高于第一门限，也可以指低于第一门限，本发明不限定。例如，当应用层测量结果对应的AS测量结果低于第一门限时，终端设备的RRC层才保存该应用层测量结果，从而可以只针对AS测量结果低于第一门限的应用层测量结果进行分析，从而优化网络。
可选的，所述门限来自于所述接入网设备。例如，接入网设备在向终端设备发送应用层测量配置或第一指示信息时携带第一门限。可选的，当终端设备的RRC层收到第一指示信息之后，终端设备才会执行步骤703；或者当终端设备说到应用层测量配置之后，就执行步骤703，即不管是否收到第一指示信息。
可选的，AS测量结果指服务小区的信号质量(比如RSRP/RSRQ)或者丢包率等。接入网设备可见的测量结果参见图3对应的方案中的描述。
本实施例中，步骤701和702不限定先后顺序。
通过上述保存应用层测量结果的方案，只有当应用层测量结果对应AS测量结果或接入网设备可见的测量结果满足第一门限对应的条件时，终端设备的RRC层才保存该应用层测量结果，从而在终端设备的内存有限的情况下，有选择的保存应用层测量结果，提高了存储效率。
上述实施例一至四中，可选的，当UE的RRC层从接入网设备收到暂停QoE测量上报的指示信息，对于已经那些已经传提给PDCP层的QoE测量结果，该如何处理？方法一：UE会继续把这些QoE测量结果发送给接入网设备。方法二：UE不会继续把这些QoE测量结果发送给接入网设备，UE会把那些还没有成功发送给接入网设备的QoE测量结果(比如保存在UE的PDCP层的QoE测量结果)重新保存在UE的RRC层。
可选的，还可以包括步骤：
步骤A.接入网设备向UE发送恢复QoE测量上报的指示信息。
接入网设备可能只是通知UE暂停某些QoE测量上报，指示信息中可携带业务类型、slice ID或其他标识来指示暂停上报那些QoE测量。
步骤B.UE向接入网设备发送保存的QoE测量结果
当UE的RRC层从上层收到恢复QoE测量上报的指示信息，UE的RRC层开始把保存的QoE测量结果发送给UE的PDCP层。具体的，UE生成RRC消息，RRC消息中携带一个或多个保存的QoE测量结果。UE通过RRC消息把QoE测量结果发送给接入网设备。
实施例五
本实施例提供了一种基于PDCP的应用层测量结果保存方法，如图8所示，包括如下步骤：
801.所述终端设备的RRC层接收来自于接入网设备的第一指示信息，所述第一指示信息指示所述终端设备暂停应用层测量结果上报。
可选的，在步骤801之前，终端设备从接入网设备接收应用层测量配置以及终端设备的RRC层把应用层测量配置发送给终端设备的RRC层的上层。例如具体可参见前面图3中的描述。可选的，在步骤801之前，终端设备的RRC层可以向终端设备的RRC层的上层发送第一能力信息。第一能力信息的描述参见图4的描述。
802.所述终端设备的RRC层向终端设备的PDCP层发送第二指示信息，指示暂停应用层测量结果上报。
可选的，第二指示信息还可以指示所述终端设备的的PDCP层不再处理后续收到的QoE测量结果。可选的，当终端设备的PDCP层收到第二指示信息之后，对于已经那些已经传提给PDCP层的QoE测量结果，该如何处理？方法一：终端设备会继续把这些QoE测量结果发送给接入网设备。方法二：终端设备不会继续把这些QoE测量结果发送给接入网设备，终端设备会把那些还没有成功发送给接入网设备且已经被PDCP层处理为PDCP PDU的QoE测量结果对应的PDCP PDU重新恢复为PDCP业务数据单元(service data unit,SDU),即PDCP层把这些还没有成功发送给接入网设备站的测量结果以PDCP SDU的形式保存在PDCP层。
803.所述PDCP层启动第一定时器，所述第一定时器对应从RRC层新收到的第一应用层测量结果。
在所述终端设备的RRC层收到第一指示信息之后，所述终端设备的RRC层从RRC层的上层收到新收到的第一应用层测量结果时，所述终端设备的RRC层把新收到的第一应用层测量结果发送给所述PDCP层。可选的，所述终端设备的RRC层会把第一应用层结果封装在RRC消息之后，再把该RRC消息发送给所述PDCP层(该RRC消息在PDCP层可以称为PDCP SDU)。
可选的，所述终端设备的PDCP层可以在收到第二指示信息之后，才对从RRC层收到的应用层测量结果启动第一定时器，也可以即使没有收到第二指示信息，终端设备的PDCP层对从RRC层收到的应用层测量结果也启动第一定时器。
804.当所述第一定时器超时时，所述PDCP层丢弃所述第一应用层测量结果。
可选的，当第一定时器超时时，所述PDCP层可以丢弃所有应用层测量结果。
可选的，上述方法还包括步骤：
805.所述PDCP层启动第二定时器，所述第二定时器对应从RRC层新收到的第二应用层测量结果；
具体描述类似步骤803中第一定时器的描述。
806.当所述第二定时器超时时，所述PDCP层丢弃所述第二应用层测量结果。
可选的，所述第一定时器的时长由所述接入网设备指示。比如在接入网设备下发第一指示信息或应用层测量配置或接入网设备配置上报QoE测量结果的无线信令承载时指示第一定时器的时长。
可选的，所述第二定时器的时长由所述接入网设备指示。比如在接入网设备下发第二指示信息或应用层测量配置或接入网设备配置上报QoE测量结果的无线信令承载时指示第二定时器的时长。
可选的，上述方法还包括步骤：
807.在所述第一定时器超时前，所述PDCP层将来自于所述RRC层的第一业务类型的应用层测量结果保存为PDCP SDU。
即所述终端设备的PDCP层从所述终端设备的RRC层收到携带QoE测量结果的PDCP SDU之后，所述终端设备的PDCP层并不进行PDCP层的处理，即这些QoE测量结果只是以PDCP SDU的形式保存在PDCP层。
可选的，上述方法还包括步骤：
808.所述终端设备的RRC层接收来自于所述接入网设备的第三指示信息，所述第三指示信息指示所述终端设备恢复应用层测量结果上报。
809.所述终端设备的RRC层向终端设备的PDCP层发送第四指示信息，所述第四指示信息指示恢复应用层测量结果上报。
可选的，第四指示信息可能是指示PDCP层恢复QoE测量结果的处理。
通过上述保存应用层测量结果的方案，当发生暂停QoE测量上报时，终端设备把新收到的应用层测量结果保存在PDCP层，从而无需在RRC层进行特殊的处理，降低了终端设备的复杂度，提高了存储效率。
实施例六
本实施例提供了一种AS的上层保存应用层测量结果的方法，如图9所示，包括如下步骤：
901.终端设备的RRC层的上层从RRC层接收第一指示信息，第一指示信息指示所述终端设备暂停应用层测量结果上报。
可选的，所述RRC层可以是AS的其他层。RRC层的上层可以是应用层，也可能是其他可以进行QoE测量的层。
可选的，在步骤901之前，终端设备从接入网设备接收应用层测量配置以及终端设备的RRC层把应用层测量配置发送给终端设备的RRC层的上层。例如具体可参见前面图3中的描述。可选的，在步骤901之前，终端设备的RRC层可以向终端设备的RRC层的上层发送第一能力信息。第一能力信息的描述参见图4的描述。
902.终端设备的RRC层的上层获得第一业务类型的应用层测量结果。
终端设备的RRC的上层收到第一指示信息之后，终端设备的RRC的上层继续QoE测量，但终端设备RRC的上层并不是按照之前应用层测量配置中的上报规则或测量规则进行处理。
可选的，如果之前是周期上报或周期测量，则终端设备的RRC的上层修改为等业务结束之后才上报；或者，终端设备的RRC层的上层等收到恢复QoE测量上报的指示信息之后才，上报从暂停QoE测量上报到恢复QoE测量上报的时间段内的QoE测量结果；或者，UE的AS层的上层等收到恢复QoE测量上报的指示信息之后才，终端设备的RRC层的上层下次上报的QoE测量结果会包括从暂停QoE测量上报到恢复QoE测量上报的时间段内的应用层的性能(即终端设备的RRC层的上层按照暂停QoE上报之前的规则继续上报，只是下一个QoE测量结果包括了从暂停QoE测量上报到恢复QoE测量上报的时间段内的应用层的性能，也可能包括了其他时间段内的应用层的性能。
903.所述终端设备的RRC层的上层，在对应的业务结束后，或者在收到恢复应用层测量上报指示信息后，上报应用层测量结果。
可选的，所述应用层测量结果指示了所述RRC层的上层暂停上报时刻至恢复上报时刻之间的应用层测量结果。
例如，在T1时刻暂停，在T2时刻恢复，按照暂停之前的规则，UE应该在T0(T1>T0)、T3(T2>T3>T1)和T4(T4>T2>T3>T1)时刻产生测量结果,T4时刻产生的QoE测量结果是反映T3～T4时刻段内的测量结果。在本方案中，收到恢复QoE测量上报的指示信息之后，UE的AS的上层在T4时刻产生测量结果，该测量结果反映T0～T4时刻段内的测量结果)。
可选的，上述方法还可以包括：
904.所述终端设备的RRC层的上层从RRC层接收第二指示信息，第二指示信息指示所述终端设备恢复应用层测量结果上报。
可选的，UE的RRC层的上层恢复之前的应用层测量配置中的上报规则或测量规则。
通过上述保存应用层测量结果的方案，当发生暂停QoE测量上报时，终端设备的RRC层的上层不会在暂停时间段内产生应用层测量结果，但终端设备的RRC层的上层仍然在进行应用层测量，从而后续产生的应用测量结果仍然指示了暂停阶段应用层的测量结果，从而网络侧仍然能得到完整的应用层测量结果，不会出现内存空间用尽时导致丢弃应用层测量结果的问题，提高了效率。
