具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。
本公开实施例收集服务体验质量信息的方法可以应用于图1所示的无线通信系统中。参阅图1所示，该无线通信系统中包括网络设备和终端。终端通过无线资源与网络设备相连接，并进行数据传输。
可以理解的是，图1所示的无线通信系统仅是进行示意性说明，无线通信系统中还可以包括其他网络设备，例如还可以包括核心网设备、无线中继设备和无线回传设备等，在图1中未画出。本公开实施例对该无线通信系统中包括网络设备数量和终端数量不做限定。
进一步可以理解的是，本公开实施例无线通信系统，是一种提供无线通信功能的网络。无线通信系统可以采用不同的通信技术，例如码分多址(code division multiple access,CDMA)、宽带码分多址(wideband code division multiple access，WCDMA)、时分多址(time division multiple access，TDMA)、频分多址(frequency division multiple access，FDMA)、正交频分多址(orthogonal frequency-division multiple access，OFDMA)、单载波频分多址(single Carrier FDMA，SC-FDMA)、载波侦听多路访问/冲突避免(Carrier Sense Multiple Access with Collision Avoidance)。根据不同网络的容量、速率、时延等因素可以将网络分为2G(英文：generation)网络、3G网络、4G网络或者未来演进网络，如5G网络，5G网络也可称为是新无线网络(New Radio，NR)。为了方便描述，本公开有时会将无线通信网络简称为网络。
进一步的，本公开中涉及的网络设备也可以称为无线接入网设备。该无线接入网设备可以是：基站、演进型基站(evolved node B，基站)、家庭基站、无线保真(wireless fidelity，WIFI)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为NR系统中的gNB，或者，还可以是构成基站的组件或一部分设备等。应理解，本公开的实施例中，对网络设备所采用的具体技术和具体设备形态不做限定。在本公开中，网络设备可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域(小区)内的终端进行通信。此外，当为车联网(V2X)通信系统时，网络设备还可以是车载设备。
进一步的，本公开中涉及的终端，也可以称为终端设备、用户设备(User Equipment，UE)、移动台(Mobile Station，MS)、移动终端(Mobile Terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备，例如，终端可以是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：智能手机(Mobile Phone)、客户前置设备(Customer Premise Equipment，CPE)，口袋计算机(Pocket Personal Computer，PPC)、掌上电脑、个人数字助理(Personal Digital Assistant，PDA)、笔记本电脑、平板电脑、可穿戴设备、或者车载设备等。此外，当为车联网(V2X)通信系统时，终端设备还可以是车载设备。应理解，本公开实施例对终端所采用的具体技术和具体设备形态不做限定。
相关技术中，为提升通信网络中用户的业务体验，从终端应用层收集特定业务(如视频、语音等)的QoE参数。QoE是指用户的业务质量体验。在3GPP网络中，QoE可以由 一些应用层参数来体现，而QMC被称为QoE测量收集。运营商通过网络配置从UE应用层收集的特定业务(例如，视频、语音等)的QoE参数的手段。运营商可以通过QMC来获得网络中用户的业务体验，定位体验不好的用户和问题，分析并优化用户体验。
相关技术中支持网络设备可以读取部分的QoE参数。网络设备基于读取的部分QoE参数可以用于无线网络优化。其中，网络设备读取的用于无线网络优化的部分QoE参数，可以理解为是对网络设备可见的QoE参数。对网络设备可见的QoE参数可以称为RVQoE。
其中，目前主要由终端收集RVQoE，并按照固定的预设时间间隔向网络设备上报RVQoE信息，网络设备基于终端上报的RVQoE信息进行网络优化。然而，如果终端在多个网络设备间移动，进行切换，若采用上述方式进行QoE的测量，由于上报RVQoE信息的时间，与终端切换过程无关，故有可能出现终端发生了多次切换后，上报RVQoE信息。此种情况下，终端上报的RVQoE信息很可能反映的是终端在多个网络设备下的业务体验。并且，此种情况下也有可能出现终端上报的RVQoE信息也很有可能不是发送给为终端配置RVQoE的网络设备，这样就使得为终端配置RVQoE的网络设备(即需要根据RVQoE信息来进行优化的网络设备)无法得到终端在该网络设备下的RVQoE信息，进而无法根据对应的RVQoE信息来进行网络优化。
图2示出了终端在进行切换场景下上报RVQoE信息的过程示意图。参阅图2所示，终端在gNB1、gNB2以及gNB3三个网络设备之间移动，终端进行一次RVQoE信息上报的时间内，终端并从gNB1切换到gNB2，又从gNB2切换到gNB3。此时，终端向gNB3上报RVQoE信息，并不是向为终端配置RVQoE信息上报的gNB1上报该RVQoE信息。并且，终端上报的RVQoE信息可能对应终端在多个在gNB1、gNB2以及gNB3三个网络设备下的体验。这种情况下gNB3收集到的RVQoE信息并不适用于切换优化，并且gNB1并不能收集到RVQoE信息。
故，针对切换场景下提供一种行之有效的收集RVQoE信息的方法是有必要的。
有鉴于此，本公开实施例提供一种收集RVQoE信息的方法，在该方法中，配置与切换相关的RVQoE配置信息，终端根据该与切换相关的RVQoE配置信息收集RVQoE信息。
其中，本公开中涉及的与切换相关的RVQoE配置信息可以理解为是用于切换场景中使用的用于配置收集RVQoE信息的配置信息。例如，该与切换相关的RVQoE配置信息可以是用于配置切换前进行RVQoE信息收集的配置信息。该与切换相关的RVQoE配置信息也可以是用于配置切换过程中进行RVQoE信息收集的配置信息。该与切换相关的RVQoE配置信息可以是用于配置切换后进行RVQoE信息收集的配置信息。
一种实施方式中，本公开实施例提供的收集RVQoE信息的方法中涉及的与切换相关 的RVQoE配置信息为终端进行一次切换过程中涉及的RVQoE配置信息。本公开实施例以下为描述方便，将终端进行一次切换过程中涉及的网络设备称为第一网络设备和第二网络设备。其中，第一网络设备可以是终端进行切换的源基站，第二网络设备可以是终端进行切换的目标基站。
本公开实施例提供的一种收集RVQoE信息的方法中，由第一网络设备(进行切换的源基站)配置与切换相关的RVQoE配置信息。
图3是根据一示例性实施例示出的一种收集RVQoE信息的方法流程图。如图3所示，收集RVQoE信息的方法用于终端中，包括以下步骤。
在步骤S11中，确定与切换相关的RVQoE配置信息。
在步骤S12中，基于与切换相关的RVQoE配置信息，收集RVQoE信息。
本公开实施例中，与切换相关的RVQoE配置信息，用于在切换场景中进行RVQoE信息收集。在切换场景中进行RVQoE信息收集，可以是在切换前，切换中和/或切换后收集RVQoE信息。
