需要说明的是，网络数据分析功能实体接收到消息1后，还可以向应用功能实体返回响应消息，以通知应用功能实体接收到消息1。
步骤303：终端向网络数据分析功能实体发送通知消息。
其中，步骤303中所述终端可以为：使用应用功能实体提供的应用的一个或多个终端用户，如：可以为访问该应用的所有终端用户，或者为访问该应用的一些特定终端用户，如贵宾(Very Important Person，VIP)用户或者某个特定区域内的用户等。

在本申请各实施例中，若终端检测到其访问应用功能实体提供的应用时，出现时延长、速率低等用户体验不佳的现象，则执行步骤303；或者，若终端在步骤303之前，接收到应用功能实体发送的消息2，则执行步骤303，这一过程对用户来说是不感知的；或者，若终端在步骤303之前，接收到应用功能实体发送的消息2，并通过用户界面(User Interface，UI)向用户发送是否同意对终端上的应用进行数据收集的提示信息后，接收到用户发送的用于指示对终端上的应用进行数据收集的确认指令，则执行步骤303，即终端在接收到用户的指示后才向网络数据分析功能实体发送通知消息，以此提高用户体验。
其中，消息2可以为应用消息，可以包括应用的ID，消息2可以用于指示终端上 报应用对应的数据。可选的，应用功能实体可以向终端上的与应用对应的APP客户端推送消息2。需要说明的是，本申请中，应用功能实体向终端发送消息2的过程可以在步骤301之前执行，也可以在步骤301之后、步骤303之前执行，还可以与步骤301同时执行，不予限制。此外，终端接收到应用功能实体发送的消息2后，还可以向应用功能实体返回响应消息，以通知应用功能实体接收到消息2。
如图3a所示，假设终端为手机，手机的收发器在接收到消息2后，在显示屏上弹出一提示框(如图3a中3011所示)，是否同意对终端的进行数据收集，若用户点击提示框中的按钮“是”，则手机的处理器确定对终端进行数据收集，执行步骤303所述过程。
具体的，为了降低信令开销，终端可以通过现有的会话建立流程(Session Establishment procedure)或会话修改流程(Session Modification procedure)或者业务请求流程(Service Request procedure)或配置更新流程(Configuration Update procedure)或者其他流程向网络数据分析功能实体发送通知消息，不予限制。以终端通过会话建立流程向网络数据分析功能实体发送通知消息为例，终端向AMF发起包括通知消息的会话建立请求，AMF接收到包括通知消息的会话建立请求(Session Establishment Request)后，向会话管理功能(Session Manager Function，SMF)发送包括通知消息的会话管理上下文请求(Session Management Context Request)，SMF接收到包括通知消息的会话管理上下文请求，且获取到终端的上下文后，向策略控制功能实体(如：PCF)发送包括通知消息的会话管理相关策略建立(SM Policy Association Establishment)请求或会话管理相关策略修改(SM Policy Association Modification)请求，策略控制功能实体接收到包括通知消息的会话管理相关策略建立请求或会话管理相关策略修改请求后，向网络数据分析功能实体发送通知消息，以便后续策略控制功能实体接收到网络数据分析功能实体发送的测量参数后，将测量参数包括在会话管理相关策略建立响应或会话管理相关策略修改响应中下发下去。同理，终端通过现有的会话修改流程或者业务请求流程或配置更新流程发送通知消息的过程可参照该过程，即终端将通知消息包括在会话修改请求或者业务请求或配置更新请求中发送出去，后续通过网络侧实体间的消息传递将通知消息发送至策略控制功能实体，以便策略控制功能实体接收到通知消息后，将通知消息发送给网络数据分析功能实体。
步骤304：网络数据分析功能实体接收通知消息，向策略控制功能实体发送消息3。
其中，消息3可以包括应用的ID和第一测量参数，消息3可以用于请求策略控制功能实体发送该应用对应的测量参数。策略控制功能实体可以为网络数据分析功能实体所处公共陆地移动网络(Public Land Mobile Network，PLMN)中的任一策略控制功能实体。
可选的，若PLMN中有且仅有一个策略控制功能实体，且网络数据分析功能实体保存有策略控制功能实体的地址(如：策略控制功能实体的服务化接口的地址Npcf)，则网络数据分析功能实体根据其保存的策略控制功能实体的地址向策略控制功能实体发送消息3；或者，若PLMN中存在多个策略控制功能实体，则网络数据分析功能实体向多个策略控制功能实体均发送消息3，由策略控制功能实体根据自身是否存储该应用对应的用户策略(UE policy)判断是否接收消息3，如：若策略控制功能实体保存该应用对应的UE policy，则接收消息3，否则拒绝接收消息3。
步骤305：策略控制功能实体接收消息3，向终端发送第二测量参数。
其中，为了降低信令开销，策略控制功能实体可以借助于现有的会话建立流程或会话修改流程或者业务请求流程或配置更新流程或者其他流程向终端发送第二测量参数。以策略控制功能实体通过会话建立流程向终端发送第二测量参数为例，策略控制功能实体接收到消息3后，将第二测量参数包括在会话管理相关策略建立响应或会话管理相关策略修改响应中发送给SMF，SMF接收到会话管理相关策略建立响应或会话管理相关策略修改响应后，向AMF发送包括第二测量参数的会话管理上下文响应，AMF接收到会话管理上下文响应后，向终端发送包括第二测量参数的会话建立响应。同理，策略控制功能实体通过现有的会话修改流程或者业务请求流程或配置更新流程向终端发送第二测量参数的过程可参照该过程，如：策略控制功能实体将第二测量参数包括在会话管理相关策略修改响应中发送给SMF，SMF将第二测量参数发送给AMF，AMF将第二测量参数发送给终端。
其中，第二测量参数可以包括终端测量参数、空口测量参数和PCC rule测量参数中的至少一种信息。如：当第一测量参数为终端测量参数时，第二测量参数可以为终端测量参数；当第一测量参数为终端测量参数和空口测量参数时，第二测量参数可以为终端测量参数和空口测量参数；当第一测量参数为终端测量参数和用于指示PCC rule是否需要测量的指示信息，且该指示信息指示PCC rule需要测量时，第二测量参数可以为终端测量参数和PCC rule测量参数；当第一测量参数为终端测量参数和用于指示PCC rule是否需要测量的指示信息，且该指示信息指示PCC rule不需要测量时，第二测量参数可以为终端测量参数；当第一测量参数为终端测量参数、空口测量参数和用于指示PCC rule是否需要测量的指示信息，且该指示信息指示PCC rule需要测量时，第二测量参数可以为终端测量参数、空口测量参数和PCC rule测量参数；当第一测量参数为终端测量参数、空口测量参数和用于指示PCC rule是否需要测量的指示信息，且该指示信息指示PCC rule不需要测量时，第二测量参数可以为终端测量参数和空口测量参数。PCC rule测量参数可以为保障比特速率(Guaranteed Bit Rate，BGR)等。具体的，该可能的设计可参照下述图4所示。
需要说明的是，由于接入网设备可以收集空口测量参数对应的数据，所以，在本申请实施例中，为了降低终端收集数据的负担，可以仅将终端测量参数，或者终端测量参数和PCC rule测量参数发送给终端，将空口测量参数发送给接入网设备，由接入网设备收集空口测量参数对应的数据后上报给网络数据分析功能实体。具体的，该可能的设计可参照下述图5所述。
步骤306：终端接收第二测量参数，收集第二测量参数对应的数据。
其中，终端可以在空闲(idle)态下收集第二测量参数对应的数据，还可以在连接(connected)态下收集第二测量参数对应的数据，不予限制。其中，空闲态可以指：终端与网络侧设备之间未建立非接入层(Non-Access Stratum，NAS)信令连接；连接态可以指：终端与网络侧设备之间已建立NAS信令连接。具体的，终端收集第二测量参数对应的数据的过程可参照现有技术，本申请实施例对此不再赘述。
步骤307：终端向网络数据分析功能实体发送收集到的数据，网络数据分析功能实体接收终端收集到的数据。
其中，终端可以通过会话释放流程(Session Release procedure)向网络数据分析功能实体发送收集到的数据，如：终端收集完第二测量参数对应的数据后，可以根据收集到的数据确定释放该应用对应的某个会话，向AMF发起包括收集到的数据的会话释放请求，AMF接收到包括收集到的数据的会话释放请求(Session Release Request)后，向SMF发送该会话释放请求，SMF接收到会话释放请求后，向策略控制功能实体发送包括收集到的数据的会话管理相关策略终止(SM Policy Association Termination)请求，策略控制功能实体接收到包括收集到的数据的会话管理相关策略终止请求后，向网络数据分析功能实体发送收集到的数据；或者，终端将收集到的数据包括在终端路由选择策略(UE Route Selection Policy，URSP)中向网络数据分析功能实体发送；或者，终端确定重新建立一个协议数据单元(Protocol Data Unit，PDU)会话，通过会话建立流程向网络数据分析功能实体发送收集到的数据，该过程可参照终端通过会话建立流程向网络数据分析功能实体发送通知消息的过程，不再赘述。
基于图3所示方法，应用功能实体将其提供的应用的情况上报给网络数据分析功能实体，网络数据分析功能实体根据应用功能实体上报的信息获取与该应用对应的测量参数，将测量参数下发给策略控制功能实体，策略控制功能实体向终端发送测量参数，以便终端收集测量参数对应的数据后，将收集到的数据上报给网络数据分析功能实体。如此，网络侧设备可以从终端收集应用对应的数据，并根据收集到的数据对该应用进行网络资源或者本地资源的智能化调整，提升用户的网络体验。
