Description

一种通信方法及装置
相关申请的交叉引用
本申请要求在2022年11月03日提交中国专利局、申请号为202211371935.1、申请名称为“一种通信方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种通信方法及装置。
背景技术
应用层测量也可称为体验质量(quality of experience，QoE)测量，用于确定业务的流量、业务的吞吐量或业务的时延等信息。比如，接入网设备可以将应用层测量配置信息发送给终端设备，进而终端设备根据应用层测量配置信息进行应用层测量。通过应用层测量结果可以确定用户在使用这些业务时的用户体验，从而更好地优化网络以提高用户的体验。
广播是指一个发送方进行数据发送，而多个接收方对数据进行接收的传输技术。通过广播的方式进行传输的业务可以称为广播业务，例如接入网设备发送广播业务的数据，多个终端设备对广播业务的数据进行接收。其中，广播业务比如为第5代(the 5th generation，5G)通信系统引入的多播/广播服务(multicast broadcast service，MBS)业务。
然而，如何实现广播业务的应用层测量，仍需进一步研究。
发明内容
本申请提供了一种通信方法及装置，用于提高接入网设备对终端设备执行广播业务的应用层测量的可控性。
第一方面，本申请实施例提供一种通信方法，该方法可以应用于终端设备或者终端设备中的部件(例如电路或者芯片)，以该方法应用于终端设备为例，在该方法中，终端设备接收来自接入网设备的第一信息，所述第一信息用于指示所述接入网设备具有至少一个广播业务的应用层测量配置信息，所述至少一个广播业务包括第一广播业务；以及，根据所述第一信息，向所述接入网设备发送第二信息，所述第二信息用于指示所述终端设备对所述第一广播业务感兴趣；接收来自所述接入网设备的所述第一广播业务的应用层测量配置信息，所述第一广播业务的应用层测量配置信息用于对所述第一广播业务进行应用层测量。
采用上述方法，终端设备可以根据第一信息上报第二信息，进而接入网设备可以根据第二信息，有针对地向终端设备发送广播业务的应用层测量配置信息(即通过单播的方式发送)，便于接入网设备的灵活调控。可选地，当终端设备对广播业务不感兴趣时，终端设备可以不向接入网设备发送第二信息，进而接入网设备也不再向该终端设备发送广播业务的应用层测量配置信息，相比于接入网设备以广播的方式发送广播业务的应用层测量配置(即使终端设备对第一广播业务不感兴趣，终端设备也需要去接收接入网设备广播的广播业务的应用层测量配置信息，)来说，可以避免终端设备执行不必要的接收，节省终端设备的功耗。

以5G通信系统为例，核心网200中可以包括会话管理功能(session management function，SMF)网元、用户面功能(user plane function，UPF)网元、策略控制功能(policy control function，PCF)网元、应用功能(application function，AF)网元等。有关上述各个核心网网元的具体描述，可以参考第三代合作伙伴计划(3rd generation partnership project，3GPP)的相关技术规范。
三、OAM网元300
本申请实施例中的OAM网元是指能够向接入网设备发送测量任务的实体，其中测量任务比如为体验质量(quality of experience，QoE)测量任务。OAM网元还可以向接入网设备发送接入网设备的配置信息。OAM网元可以是独立于核心网和无线接入网之外的网元或功能实体。
可以理解的是，本申请实施例中的技术方案还可以应用于其他通信系统中，相应的名称也可以用其他通信系统中的对应功能的名称进行替代。图1仅为便于理解而示例的简化示意图，该通信系统中还可以包括其它设备，图1中未画出。
下面先对本申请实施例所涉及的相关技术特征进行解释说明。需要说明的是，这些解释是为了让本申请实施例更容易被理解，而不应该视为对本申请所要求的保护范围的限定。
一、应用层测量
在图1所示意的通信系统中，核心网网元或OAM网元可以向接入网设备下发测量任务，进而接入网设备可以指示终端设备执行应用层测量。
其中，应用层测量是指对终端设备的应用层的性能所进行的测量。对于一些流类业务或者语音业务来说，流类业务比如包括流服务(streaming service，SS)，语音业务比如包括互联网协议(internet protocol，IP)多媒体系统(IP multi-media system，IMS)的多媒体电话服务(multimedia telephony service for IMS，MTSI)，单纯的信号质量或接入层的通信质量却并不能体现用户在使用这些业务时的用户体验。运营商想要知道用户的体验，从而才能更好地优化网络质量以提升用户体验。因此，应用层测量实际上属于一种提高用户网络使用体验的重要测量方式。
应用层测量的发起方式可以分为基于信令的应用层测量和基于管理的应用层测量。对于基于信令的应用层测量来说，测量任务可以由核心网网元通知接入网设备以对特定的某个终端设备发起应用层测量。对于基于管理的应用层测量来说，并不是针对某个特定终端设备的应用层测量，而是先由接入网设备从OAM网元(或网管，本申请实施例中以OAM网元为例)接收进行应用层测量的消息，再基于一定的策略从接入该接入网设备的终端设备中选择合适的终端设备发起应用层测量。
图2为本申请实施例提供的一种应用层测量的流程示意图。如图2所示，该流程包括如下步骤：
S201a或S201b，接入网设备获取应用层测量请求消息，应用层测量请求消息中携带有应用层测量配置信息。
在一种可选的实施方式中，应用层测量配置信息在应用层测量请求消息中可以以一种透明的容器(container)形式进行承载。容器是一种类似于包裹的承载方式，只有当容器到达最终的目的地时才会 被打开(即解析)，本申请实施例中，接入网设备不会解析容器中的内容(即使接入网设备有能力解析，接入网设备也不会解析容器中的内容)。这种情况下，由于应用层测量是在终端设备的应用层测量层中执行，因此应用层测量配置信息所在的容器只有在达到终端设备的应用层测量层后才会被解析，而在除终端设备的应用层测量层以外的其它层或其他设备(例如接入网设备)中并不会被解析，而是直接以容器的形式进行封装转发。应用层测量层为下面描述中的接入层的上层。
在又一种可选的实施方式中，应用层测量配置信息在应用层测量请求消息中也可以以一种非容器形式进行承载。这种情况下，除终端设备的应用层以外的其它层或其它设备(例如接入网设备)也可以解析应用层测量请求消息而得到应用层测量配置信息的具体内容。
在又一种可选的实施方式中，应用层测量配置信息中的一部分内容可以采用容器形式进行承载，另外一部分内容可以采用非容器形式进行承载。应用层测量配置信息在应用层测量请求消息中的承载方式有很多，此处不再一一介绍。
此外，应用层测量请求消息中除了包括应用层测量配置信息以外，还可以包括其它信息，例如QoE参考(QoE reference)、测量收集实体(measurement collection entity，MCE)的地址信息、测量范围信息、本次测量所对应的业务类型中的至少一项。这些信息可以不以容器的形式承载在应用层测量请求消息中，因此这些信息可以被接入网设备进行解析。
其中，QoE reference可以是一个全局唯一的标识，用于标识网络请求的这个应用层测量或QoE测量(或用于接入网设备和MCE标识应用层测量任务)。比如，QoE reference是由公共陆地移动网络(public land mobile network，PLMN)(PLMN由移动国家码(mobile country code，MCC)和移动网络码(mobile network code，MNC)构成)和QoE测量收集标识构成，QoE测量收集标识是由管理系统或运营商分配的。MCE的地址信息比如包括MCE的IP地址，MCE的IP地址用于接入网设备在接收到终端设备上报的应用层测量结果之后，把对应的测量结果发送给MCE。
S202，接入网设备根据应用层测量请求消息，确定要执行应用层测量的终端设备。
本申请实施例中，当应用层测量的发起方式不同时，接入网设备确定要执行应用层测量的终端设备的方式也不同。示例来说：
当应用层测量的发起方式为基于信令的应用层测量时，应用层测量任务由核心网发起，而接入网设备可以按照S201a所示意的从核心网接收针对于某个特定终端设备的应用层测量请求消息。在这种情况下，由于接入网设备在终端设备接入核心网时为该终端设备和核心网的通信分配了一个专门的通信接口，因此接入网设备从哪个通信接口接收到应用层测量请求消息，即可根据通信接口与终端设备的对应关系确定出要对哪个终端设备发起应用层测量。
当应用层测量的发起方式为基于管理的应用层测量时，应用层测量任务由OAM网元发起，而接入网设备可以按照S201b所示意的从OAM网元接收测量请求消息。在这种情况下，接入网设备可以先根据解析该应用层测量请求消息得到的待测量的区域范围等限制条件，再根据这些限制条件确定出接入该接入网设备的全部终端设备中哪些终端设备符合此次应用层测量的需求，进而将这些符合需求的终端设备作为要执行本次应用层测量的终端设备。
需要说明的是，本申请实施例中，“本次应用层测量”具体是指从本次测量任务开始至本次测量任务结束的整个应用层测量，例如当要对某个会话进行应用层测量时，从该会话开始到该会话结束的整个测量时段作为本次应用层测量的测量时段。且，在一次应用层测量中，终端设备可以只上报一次应用层测量结果，例如在一次会话结束后上报该次会话的整个测量时段内测量得到的应用层测量结果，也可以上报多次应用层测量结果，例如在一次会话过程中按照5秒的周期时长周期上报每个5秒内测量得到的应用层测量结果。
应理解，在上述两种发起方式中，只有当终端设备支持应用层测量时，接入网设备才会将该终端设备作为要执行应用层测量的终端设备。而终端设备是否支持应用层测量，可以由终端设备上报给接入网设备，也可以由接入网设备向终端设备发送问询消息并接收响应消息得到，还可以由接入网设备与终端设备预配置得到，具体不作限定。
需要说明的是，上述S201a和S201b中的方案仅是一种可选的实施方式。本申请实施例中，接入网设备也可以不根据从核心网网元或OAM网元接收的应用层测量消息来确定执行应用层测量的终端设备。例如在另一种可选的实施方式中，接入网设备还可以根据自己生成应用层测量配置信息，并根据自己的需求确定出要执行应用层测量的终端设备。
S203，接入网设备将应用层测量配置信息承载在RRC消息中发送给要执行应用层测量的终端设备中的接入层(access stratum，AS)。
在上述S203中，应用层测量配置信息在RRC消息中的数据承载形态也可以为容器形式、或非容器形式、或两者混合的形式，参见上述S201a或S201b中的介绍。
可选地，RRC消息中除了包括应用层测量配置信息之外，还包括其它信息，例如应用层测量标识和/或本次测量所对应的业务类型(用于指示要对哪种业务类型的业务执行应用层测量)。其中，应用层测量标识可以是由接入网设备为终端设备生成的，用于标识应用层测量配置信息。一般而言，应用层测量标识和QoE reference对应，且接入网设备可以保存应用层测量标识和QoE reference之间的对应关系。
S204，终端设备中的AS将应用层测量配置信息发送给终端设备中的AS的上层。
在上述S204中，由于AS并不是要执行应用层测量的最终层，因此AS可以将应用层测量配置信息转发给AS的上层。AS的上层可以是指终端设备的应用层，也可以是指一个专门进行应用层测量的层，还可以是介于应用层和AS之间的一个层。当AS的上层是介于应用层和AS之间的一个层时，AS的上层需要进一步转发应用层测量配置信息，直至将应用层测量配置信息转发给最终测量的层。应理解，当RRC消息中同时包括应用层测量配置信息和本次测量所对应的业务类型和/或应用层测量标识时，AS还可以将应用层测量配置信息和待测量的业务类型和/或应用层测量标识同时发送给AS的上层。
示例性地，终端设备的AS可以通过一个AT(attention)命令(command)把以上信息发送给AS的上层。比如，上述AT命令可以为AT command+CAPPLEVMC(command application level measurement configuration)。
S205，终端设备中的AS的上层执行应用层测量，得到应用层测量结果。
本申请实施例中，若AS的上层同时接收到应用层测量配置信息和本次测量所对应的业务类型，则AS的上层可以根据应用层测量配置信息，对本次测量所对应的业务类型所对应的应用进行应用层测量，得到应用层测量结果。应用层测量结果可以占据1字节～8000字节中的任一字节。
在上述S205中，如果终端设备在执行应用层测量的过程中发生了服务小区的切换，则切换后的服务小区所属的接入网设备会重新判断该终端设备切换后的服务小区是否属于待测量的区域范围，若属于，则切换后的服务小区所属的接入网设备可以向终端设备发送继续测量的指示信息以指示终端设备继续执行测量，或切换后的服务小区所属的接入网设备也可以无需特殊地向终端设备发送指示信息，这种情况下终端设备默认继续进行测量。若不属于，则切换后的服务小区所属的接入网设备可以向终端设备发送停止测量的指示信息以指示终端设备暂停测量，或切换后的服务小区所属的接入网设备也可以向终端设备发送释放应用层测量配置信息的指示信息以指示终端设备结束测量。
S206，终端设备中的AS的上层将应用层测量结果上报给终端设备中的AS。
在上述S205和S206中，AS的上层可以按照某种设定规则执行应用层测量并上报应用层测量结果给终端设备中的AS。其中，设定规则可以是终端设备中默认的规则，也可以是应用层测量配置信息中指出的某种规则。例如，在一种可能的设定规则中，AS的上层按照应用层测量配置信息中指出的周期来执行应用层测量并上报应用层测量结果。又例如，在另一种可能的设定规则中，AS的上层在每个会话(或某一类型的会话)过程中执行应用层测量并在会话结束之后上报应用层测量结果。假设终端设备在一个会话过程中经过了5个服务小区，则AS的上层会从本次会话开始到本次会话结束的整个时段内终端设备的应用层测量结果情况上报给AS。
示例性地，AS的上层除了可以将应用层测量结果上报给AS之外，还可以上报应用层测量标识。
示例性地，AS的上层可以通过一个AT(attention)命令把以上信息发送给AS。比如，上述AT命令可以为AT command+CAPPLEVMR(command application level measurement report)。
S207，终端设备中的AS将应用层测量结果承载在RRC消息中发送给接入网设备。
在上述S207中，应用层测量结果在RRC消息中的数据承载形态也可以为容器形式、或非容器形式、或两者混合的形式，参见上述S201a或S201b中的介绍。且，RRC消息中除了可以包括应用层测量结果之外，还可以包括应用层测量标识，以便于接入网设备或其他实体获知该应用层测量结果是根据哪一应用层测量配置信息所执行的测量。
在上述S207中，如果终端设备在执行应用层测量的过程中发生了服务小区的切换，则AS会向切换后的服务小区所属的接入网设备发送应用层测量结果。这种情况下，当切换后的服务小区所属的接入网设备与切换前的服务小区所属的接入网设备不同时，发送应用层测量配置信息的接入网设备(即S203 中的接入网设备)和接收应用层测量结果的接入网设备(即S207中的接入网设备)并不是同一个接入网设备。当切换后的服务小区所属的接入网设备与切换前的服务小区所属的接入网设备相同时，发送应用层测量配置信息的接入网设备和接收应用层测量结果的接入网设备是同一个接入网设备。需要说明的是，切换前的服务小区所属的接入网设备会向切换后的服务小区所属的接入网设备发送同一应用层测量配置信息对应的应用层测量标识和QoE reference(即应用层测量标识和QoE reference之间的对应关系)。
S208，接入网设备将终端设备的应用层测量结果发送给MCE。
示例性地，接入网设备可以根据保存的应用层测量标识和QoE reference之间的对应关系及终端设备上报的应用层测量标识，获得终端设备上报的应用层测量结果对应的QoE reference；进一步地，接入网设备根据QoE reference查找到对应的MCE的IP地址，并把应用层测量结果发送给MCE。或者，接入网设备根据终端设备上报应用层测量标识获得对应的应用层测量配置信息，再根据核心网网元或OAM网元下发的应用层测量请求消息，获得应用层测量配置信息对应的MCE的IP地址，该MCE的IP地址即为应用层测量结果对应的MCE的IP地址，进而把应用层测量结果发送给MCE。
本申请实施例中，MCE在接收到终端设备的应用层测量结果后，可以根据该应用层测量结果确定用户使用该终端设备中的应用的用户体验(例如通话质量的优劣性、观看视频的流畅性等)，当用户体验较差时，MCE可以通知接入网设备为该终端设备分配更多的无线资源，以提升该终端设备的应用性能，提高用户的应用体验。
需要说明的是，本申请实施例中，上述S208仅是一种可选的步骤。在另一种可选的实施方式中，接入网设备也可以先自行利用应用层测量结果确定出用户使用该终端设备中的应用的用户体验，进而根据应用层测量结果来调整为该终端设备分配的无线资源，以提升该终端设备的应用性能，提高用户的应用体验。
二、广播业务
针对于广播业务(比如MBS业务)，目前引入了两个逻辑信道，分别为MBS控制信道(MBS control channel，MCCH)和MBS业务信道(MBS traffic channel，MTCH)，这两个逻辑信道都映射到下行共享信道(downlink shared channel，DL-SCH)上。其中，MCCH用于传输控制信息，包括广播业务的标识和MTCH的配置信息(比如广播业务关联的组无线网络临时标识(group-radio network temporary identity，G-RNTI)、接收MTCH的资源信息)。MTCH用于传输广播业务数据，每个广播业务可以对应一个MTCH，比如广播业务1对应MTCH1，广播业务2对应MTCH2。进而，终端根据MCCH中的调度信息可以接收MTCH中的广播业务的数据。
终端设备的工作状态可以包括无线资源控制(radio resource control，RRC)空闲(RRC_IDLE)态、RRC非激活(Inactive)态和RRC连接(RRC_CONNECTED)态。其中，RRC空闲态可简称为空闲态，RRC非激活态可简称为非激活态，RRC连接态可简称为连接态。终端设备可以连接态接收广播业务的数据，然而，由于接入网设备维护大量的终端设备处于连接态会耗费大量的处理资源，因此，接入网设备也可以指示终端设备进入空闲态或非激活态，并在空闲态或非激活态接收广播业务的数据。
基于上述相关技术特征的描述，目前考虑对广播业务进行应用层测量，即接入网设备从核心网网元或OAM网元接收到广播业务(比如广播业务1)的应用层测量配置信息后，可以将应用层测量配置信息发送给终端设备，以使终端设备对广播业务1进行应用层测量。
针对基于管理的应用层测量，由于接入网设备无法知晓哪些终端设备对广播业务1感兴趣，且对广播业务1感兴趣的终端设备可能处于连接态、空闲态或非激活态，因此，在一种可能的实现方式中，接入网设备接收到广播业务1的应用层测量配置信息后，可以通过广播的方式发送广播业务1的应用层测量配置信息。相应地，位于接入网设备的覆盖范围内的终端设备(可能处于连接态、空闲态或非激活态)可以接收广播业务1的应用层测量配置信息。若终端设备对广播业务1感兴趣，则终端设备可以在接收广播业务的数据时，根据广播业务1的应用层测量配置信息，对广播业务1进行应用层测量。
然而，采用上述方法，接入网设备无法知晓哪些终端设备会执行广播业务1的应用层测量，不便于接入网设备的调控，从而可能会出现较多终端设备执行广播业务1的应用层测量，并向接入网设备上报广播业务1的应用层测量结果。由于终端设备的应用层测量结果的信息量较大，若有较多终端设备向接入网设备上报广播业务1的应用层测量结果，会导致接入网设备的负担较重。
基于此，本申请实施例提供一种通信方法，用于提高接入网设备对终端设备执行广播业务的应用层 测量的可控性。
下面结合具体实施例对本申请实施例提供的通信方法进行详细描述，在具体实施例中将以基于管理的应用层测量为例进行描述，以及在具体实施例中，将以本申请实施例所提供的方法应用于图1所示的网络架构为例。另外，该方法可由两个通信装置执行，这两个通信装置例如为第一通信装置和第二通信装置，其中，第一通信装置可以是接入网设备或能够支持接入网设备实现该方法所需的功能的通信装置，当然还可以是其他装置，例如芯片或芯片系统。第二通信装置可以是终端设备或能够支持终端设备实现该方法所需的功能的通信装置，当然还可以是其他装置，例如芯片或芯片系统。为了便于介绍，在下文中，以该方法由接入网设备和终端设备执行为例，也就是，以第一通信装置是接入网设备、第二通信装置是终端设备为例。
实施例一
在实施例一中，接入网设备可以发送第一信息，以指示接入网设备具有至少一个广播业务的应用层测量配置信息；相应地，终端设备可以根据第一信息，向接入网设备上报第二信息，以指示终端设备感兴趣的广播业务；进而，接入网设备可以根据第二信息，有针对性地向终端设备发送(即通过单播的方式发送)终端设备感兴趣的广播业务的应用层测量配置信息。
图3为本申请实施例一提供的通信方法所对应的流程示意图。如图3所示，该方法包括如下步骤：
S301，接入网设备发送第一信息，第一信息用于指示接入网设备具有至少一个广播业务的应用层测量配置信息。
此处，触发接入网设备发送第一信息的因素可以有多种。比如，OAM网元可以向接入网设备发送应用层测量请求消息，应用层测量请求消息包括至少一个广播业务的应用层测量配置信息；相应地，接入网设备接收到应用层测量请求消息后，可以存储至少一个广播业务的应用层测量配置信息，并根据应用层测量请求消息发送第一信息。
其中，至少一个广播业务可以包括第一广播业务，以第一广播业务为例，应用层测量请求消息除了包括第一广播的应用层测量配置信息之外，还可以包括第一广播业务的标识。比如，第一广播业务的标识可以为第一广播业务对应的MBS会话标识，第一广播业务对应的MBS会话标识可以包括第一广播业务的临时移动组标识(temporary mobile group identifier，TMGI)。可选地，第一广播业务的MBS会话标识还包括网络标识(network identifier，NID)，NID和公共陆地移动网(public land mobile network，PLMN)标识用于标识一个独立的非公共网络。
(1)对第一信息进行说明。
本申请实施例中，第一信息可以用于触发终端设备上报第二信息。
作为一种可能的实现，第一信息用于指示接入网设备具有至少一个广播业务的应用层测量配置信息(应理解，第一信息可以不包括至少一个广播业务的应用层测量配置信息)。也就是说，第一信息通过指示接入网设备具有至少一个广播业务的应用层测量配置信息，来触发终端设备上报第二信息。其中，第一信息用于指示接入网设备具有至少一个广播业务的应用层测量配置信息，也可以替换为其它可能的描述，比如替换为第一信息用于指示接入网设备希望或需要配置至少一个广播业务的应用层测量配置信息。
此种情形下，第一信息可以是一种粗粒度的指示，即第一信息仅指示接入网设备具有至少一个广播业务的应用层测量配置信息，而未具体指示是具有哪些广播业务的应用层测量配置信息；或者，也可以是一种细粒度的指示，即第一信息指示接入网设备具有至少一个广播业务的应用层测量配置信息，且具体指示出是具有哪些广播业务的应用层测量配置信息。
其中，当是一种粗粒度的指示时，第一信息可以为指示接入网设备具有至少一个广播业务的应用层测量配置信息的指示信息；当是一种细粒度的指示时，第一信息可以包括至少一个广播业务的标识。本申请实施例中主要以第一信息是细粒度的指示为例进行描述。
示例性地，当第一信息包括至少一个广播业务的标识时，这至少一个广播业务可以是接入网设备希望或需要或感兴趣的应用层测量配置信息对应的广播业务。比如，接入网设备接收到应用层测量请求消息可以包括M个广播业务的应用层测量配置信息，则若接入网设备希望或需要或感兴趣的应用层测量配置信息对应的广播业务为M个广播业务中的N个广播业务，则接入网设备发送的第一信息可以包括N个广播业务的标识。
可选地，第一信息还包括至少一个广播业务的应用层测量配置信息对应的时间信息和/或区域信息。 以第一广播业务为例，第一广播业务的应用层测量配置信息对应的时间信息用于指示第一广播业务的应用层测量配置信息的有效时间范围；在有效时间范围内，终端设备认为接入网设备有第一广播业务的应用层测量配置信息。第一广播业务的应用层测量配置信息对应的区域信息用于指示第一广播业务的应用层测量配置信息的有效区域范围；当终端设备位于有效区域范围内，终端设备认为接入网设备有第一广播业务的应用层测量配置信息。
可以理解的是，至少一个广播业务中不同广播业务的应用层测量配置信息对应的有效时间范围或有效区域范围可以相同，或者也可以不同，具体不做限定。
上述是以第一信息通过指示接入网设备具有至少一个广播业务的应用层测量配置信息，来触发终端设备上报第二信息为例进行描述的。在其它可能的实现中，第一信息也可以不指示接入网设备具有至少一个广播业务的应用层测量配置信息，比如第一信息可以为一条专门用于触发终端设备上报第二信息(比如上报终端设备感兴趣的多播业务，或者上报终端设备是否对多播业务感兴趣)的信息或消息；此种情形下，终端设备在接收到第一信息时，可能并不感知接入网设备发送第一信息的目的是为了配置广播业务的应用层测量配置信息。也就是说，本申请实施例是通过第一信息和第二信息来实现有针对性地向终端设备发送应用层测量配置信息，但并不代表接入网设备不能用第一信息和第二信息作为其他目的。
(2)对接入网设备发送第一信息的具体实现进行说明。
接入网设备可以向接入网设备覆盖范围内的至少一个终端设备发送第一信息；相应地，至少一个终端设备可以接收第一信息，并保存第一信息。示例性地，即使终端设备的状态发生变化(比如终端设备从连接态进入空闲态或非激活态)，终端设备也可以不释放第一信息。
作为一种可能的实现，接入网设备可以以广播的方式发送第一信息，比如接入网设备可以通过广播控制信道(broadcast control channel，BCCH)或MBS控制信道或MBS业务信道发送广播消息，广播消息包括第一信息。此种情形下，接入网设备覆盖范围内的终端设备(处于连接态或空闲态或非激活态)可以接收到第一信息。
以第一信息用于指示接入网设备具有第一广播业务的应用层测量配置信息为例，第一信息可以包括指示信息和第一广播业务的标识。若接入网设备通过MBS控制信发送第一信息，则第一信息可以是作为MBS广播配置(例如第一广播业务对应的MBS会话信息)的一部分，比如接入网设备可以在第一广播业务对应的MBS会话开始时发送第一信息；相应地，终端设备接收到第一信息后，可以保存第一信息。
作为又一种可能的实现，针对于连接态的终端设备，接入网设备可以通过专用消息向终端设备发送第一信息。其中，专用消息可以为RRC重配置消息，或者也可以为RRC释放消息(比如接入网设备通过RRC释放消息指示终端设备释放RRC连接的同时，在RRC释放消息中携带第一信息)。示例性地，接入网设备可以获取终端设备的能力信息，若能力信息指示终端设备支持广播业务的应用层测量，则接入网设备向终端设备发送第一信息；否则，可以不向终端设备发送第一信息，从而节省传输资源。
S302，终端设备根据第一信息，向接入网设备发送第二信息，第二信息用于指示终端设备对广播业务感兴趣，比如第二信息用于指示终端设备对第一广播业务感兴趣。
示例性地，终端设备根据第一信息，可以获知接入网设备有至少一个广播业务的应用层测量配置信息，进而可以向接入网设备发送第二信息。
其中，第二信息指示终端设备广播业务感兴趣，可以是一种粗粒度的指示，即第二信息仅指示终端设备对广播业务感兴趣，而不指示具体对哪些广播业务感兴趣；比如，当接入网设备发送的第一信息为一种粗粒度的指示时，终端设备所反馈的第二信息也可以为一种粗粒度的指示，此种情形下，若终端设备对广播业务感兴趣，则可以根据第一信息向接入网设备发送第二信息；又比如，当接入网设备发送的第一信息为一种细粒度的指示时，终端设备所反馈的第二信息也可以为一种粗粒度的指示，此种情形下，若终端设备对至少一个广播业务中的任一广播业务感兴趣，则可以向接入网设备发送第二信息。
或者，第二信息也可以是一种细粒度的指示，即第二信息指示终端设备对广播业务感兴趣，且具体指示是对哪些广播业务(比如第一广播业务)感兴趣。比如，当接入网设备发送的第一信息为一种粗粒度的指示时，终端设备所反馈的第二信息可以为一种细粒度的指示，此种情形下，第二信息可以包括终端设备所有感兴趣的广播业务的标识。又比如，当接入网设备发送的第一信息为一种细粒度的指示时，终端设备所反馈的第二信息可以为一种细粒度的指示，此种情形下，第二信息可以包括至少一个广播业务中终端设备感兴趣的广播业务的标识。
可以理解的是，第二信息用于指示终端设备对第一广播业务感兴趣，也可以替换为其它可能的描述，比如替换为：第二信息用于指示终端设备想接收第一广播业务的数据，或想接收第一广播业务的应用层测量配置信息，或对第一广播业务的应用层测量配置信息感兴趣。相应地，下文描述中终端设备确定对至少一个广播业务中的某一或某些广播业务(比如第一广播业务)感兴趣也可以替换为其它可能的描述，比如替换为：终端设备确定想接收某一或某些广播业务(比如第一广播业务)的数据，或想接收某一或某些广播业务(比如第一广播业务)的应用层测量配置信息，或对某一或某些广播业务(比如第一广播业务)的应用层测量配置信息感兴趣。
S303，接入网设备根据第二信息，向终端设备发送第一广播业务的应用层测量配置信息；相应地，终端设备接收第一广播业务的应用层测量配置信息。
示例性地，若S302中的第二信息为一种粗粒度的指示，则在S303中，接入网设备可以向终端设备发送至少一个广播业务的应用层测量配置信息。若S302中的第二信息为一种细粒度的指示，则在S303中，接入网设备可以向终端设备发送第一广播业务的应用层测量配置信息。本申请实施例中主要以第二信息是细粒度的指示为例进行描述。
如前文所述，终端设备接收第一信息时，可能处于连接态或空闲态或非激活态，下面分别针对不同状态的终端设备对S302和S303的具体实现进行说明。
(1)空闲态或非激活态的终端设备
情形A1：
终端设备接收到第一信息后，若确定对至少一个广播业务中的某一或某些广播业务(比如第一广播业务)感兴趣，则可以发起RRC建立过程或RRC恢复过程(终端设备发起RRC建立过程或RRC恢复过程时，无需考虑当前是否即将接收或开始接收第一广播业务的数据)。
比如，终端设备可以向接入网设备发送RRC建立请求消息或RRC恢复请求消息，RRC建立请求消息或RRC恢复请求消息包括原因值和/或第二信息，即终端设备在建立或恢复终端设备与接入网设备之间的RRC连接的过程中，向接入网设备发送原因值和/或第二信息。其中，原因值用于指示向接入网设备发送RRC建立请求消息或RRC恢复请求消息的原因为需要接收广播业务的应用层测量配置信息。相应地，接入网设备接收到RRC建立请求消息或RRC恢复请求消息后，可以向终端设备发送第一广播业务的应用层测量配置信息。后续，当终端设备接收第一广播业务的数据时，终端设备可以根据第一广播业务的应用层测量配置信息对第一广播业务进行应用层测量。
其中，接入网设备可以通过RRC建立消息或RRC恢复消息向终端设备发送第一广播业务的应用层测量配置信息(即在建立或恢复RRC连接的过程中，向终端设备发送第一广播业务的应用层测量配置信息)；或者，接入网设备也可以在建立或恢复RRC连接后，通过其它可能的消息向终端设备发送第一广播业务的应用层测量配置信息，具体不做限定。
可以理解的是，若RRC建立请求消息或RRC恢复请求消息包括原因值而不包括第二信息(细粒度的指示)，或者也可以认为原因值即为第二信息(粗粒度的指示)，则接入网设备可以认为终端设备是对至少一个广播业务都感兴趣，并向终端设备发送至少一个广播业务的应用层测量配置信息。此种情形下，若至少一个广播业务包括第一广播业务和第二广播业务，终端设备对第一广播业务感兴趣，而对第二广播业务不感兴趣，则终端设备后续可以根据第一广播业务的应用层测量配置信息对第一广播业务进行应用层测量，并忽略第二广播业务的应用层测量配置信息。
若RRC建立请求消息或RRC恢复请求消息包括第二信息而不包括原因值，则可以认为第二信息隐式指示向接入网设备发送RRC建立请求消息或RRC恢复请求消息的原因为需要接收广播业务的应用层测量配置信息；或者，也可以认为第二信息即为原因值。
在其它可能的实施例中，终端设备可以向接入网设备发起RRC建立过程或RRC恢复过程，接入网设备根据终端设备发起RRC建立过程或RRC恢复过程的资源能获得第二信息。例如，接入网设备根据终端设备所使用的随机接入前导资源能获得第二信息。例如，接入网设备为由于应用层测量配置信息而发起的RRC建立过程或RRC恢复过程分配了专门的随机接入前导资源，接入网设备根据随机接入前导资源就能获知终端设备是否由于应用层测量配置信息而发起的RRC建立过程或RRC恢复过程。
情形A2：
终端设备接收到第一信息后，若确定对至少一个广播业务中的某一或某些广播业务(比如第一广播业务)感兴趣，则可以发起RRC建立过程或RRC恢复过程(终端设备发起RRC建立过程或RRC恢复 过程时，无需考虑当前是否即将接收或开始接收第一广播业务的数据)，以便于建立或恢复RRC连接；在建立或恢复RRC连接后，终端设备可以向接入网设备发送第二信息；其中，终端设备发起RRC建立过程或RRC恢复过程和发送第二信息时，均无需考虑当前是否即将接收或开始接收第一广播业务的数据。相应地，接入网设备可以根据第二信息，向终端设备发送第一广播业务的应用层测量配置信息。
也就是说，情形A2与情形A1的区别在于：情形A1中，终端设备是在建立或恢复RRC连接的过程中，向接入网设备发送第二信息；情形A2中，终端设备是在建立或恢复RRC连接后，向接入网设备发送第二信息。除此区别之外的其它内容，情形A2可以参照情形A1。
情形A3：
终端设备接收到第一信息后，若确定对至少一个广播业务中的某一或某些广播业务(比如第一广播业务)感兴趣，则可以在即将接收或开始接收第一广播业务的数据时，发起RRC建立过程或RRC恢复过程；进一步地，终端设备可以在建立或恢复RRC连接的过程中，向接入网设备发送第二信息，或者也可以是在建立或恢复RRC连接后，向接入网设备发送第二信息。
或者，终端设备接收到第一信息后，在即将接收或开始接收第一广播业务的数据时，发起RRC建立过程或RRC恢复过程；进一步地，终端设备可以在建立或恢复RRC连接的过程中，向接入网设备发送第二信息，或者也可以是在建立或恢复RRC连接后，向接入网设备发送第二信息。可选地，终端设备在即将接收或开始接收第一广播业务的数据时，可以判断第一广播业务是否属于至少一个广播业务，若是，则发起RRC建立过程或RRC恢复过程。
也就是说，情形A3与情形A1或A2的区别在于：情形A3中，终端设备是在即将接收或开始接收第一广播业务的数据时，发起RRC建立过程或RRC恢复过程。除此区别之外的其它内容，情形A3可以参照情形A1或A2的描述。
情形A4：
终端设备接收到第一信息后，若确定对至少一个广播业务中的某一或某些广播业务(比如第一广播业务)感兴趣，则可以发起RRC建立过程或RRC恢复过程(终端设备发起RRC建立过程或RRC恢复过程时，无需考虑当前是否即将接收或开始接收第一广播业务的数据)，以便于建立或恢复RRC连接；在建立或恢复RRC连接后，终端设备若确定即将接收或开始接收第一广播业务的数据，则向接入网设备发送第二信息。
此种情形下，第二信息可以为MBS兴趣指示(MBS interest indication，MII)，MII用于指示终端设备即将接收或开始接收或正在接收或有兴趣接收的广播业务。
可以理解的是，上述侧重描述了各种情形之间的区别，除区别之外的其它内容，不同情形之间可以相互参照。上述各种情形中，接入网设备根据第二信息向终端设备发送第一广播业务的应用层测量配置信息后，可以触发终端设备进入空闲态或非激活态，以便降低接入网设备的负担。
(2)连接态的终端设备
情形B1：
终端设备接收到第一信息后，若确定对至少一个广播业务中的某一或某些广播业务(比如第一广播业务)感兴趣，则可以向接入网设备发送第二信息。比如，终端设备可以通过RRC消息向接入网设备发送第二信息。终端设备发送第二信息时，无需考虑终端设备当前是否即将接收或开始接收第一广播业务的数据。相应地，接入网设备可以根据第二信息，向终端设备发送第一广播业务的应用层测量配置信息。
情形B2：
终端设备接收到第一信息后，若确定对至少一个广播业务中的第一广播业务感兴趣，则可以在即将接收或开始接收第一广播业务的数据时，向接入网设备发送第二信息。或者，终端设备接收到第一信息后，在即将接收或开始接收第一广播业务的数据时，向接入网设备发送第二信息；可选地，终端设备在即将接收或开始接收第一广播业务的数据时，可以判断第一广播业务是否属于至少一个广播业务，若是，则向接入网设备发送第二信息。
此种情形下，第二信息可以为MII。
情形B3：
终端设备接收到第一信息后，进入空闲态或非激活态。比如，接入网设备通过RRC释放消息发送第一信息，进而终端设备可以根据RRC释放消息后，进入空闲态或非激活态；又比如，终端设备在接 收到接入网设备发送的第一信息后，接收到接入网设备发送的RRC释放消息，进而可以根据RRC释放消息后，进入空闲态或非激活态。后续，终端设备可以在即将接收或开始接收第一广播业务的数据时，发起RRC建立过程或RRC恢复过程，具体可以参照上述情形A3。
此外，在上述S303中，作为一种可能的实现，接入网设备可以根据第二信息，判断出有多少个终端设备对第一广播业务感兴趣，若对第一广播业务感兴趣的终端设备的数量较多，则接入网设备可以从这多个终端设备中选择出部分终端设备，并向选择出的部分终端设备发送第一广播业务的应用层测量配置信息，从而通过接入网设备的灵活调控，避免后续有较多设备向接入网设备上报第一广播业务的应用层测量结果，导致接入网设备的负担较重。
可以理解的是，在其它可能的实施例中，接入网设备接收到来自终端设备的第二信息后，也可以根据其它可能的原因，决定是否向终端设备发送第一广播业务的应用层测量配置信息。比如，接入网设备可以根据终端设备的能力信息，决定是否向终端设备发送第一广播业务的应用层测量配置信息。其中，终端设备的能力信息可以由终端设备上报给接入网设备。又比如，接入网设备可以判断终端设备是否位于第一广播业务对应的测量范围内，若是，则可以向终端设备发送第一广播业务的应用层测量配置信息，若否，则可以不再向终端设备发送第一广播业务的应用层测量配置信息。
其中，接入网设备从核心网网元或OAM网元接收到的应用层测量请求消息中可以包括第一广播业务对应的测量范围信息，用于指示第一广播业务对应的测量范围。测量范围信息可以包括以下至少一项：测量范围包括的至少一个小区的标识；测量范围包括的至少一个TA的标识；测量范围对应的至少一个TAI的标识；测量范围包括的至少一个PLMN的标识。
或者，接入网设备也可以不考虑终端设备当前是否在测量范围内，此种情形下，接入网设备可以根据第二信息，向终端设备发送第一广播业务的应用层测量配置信息和第一广播业务对应的测量范围信息；相应地，终端设备接收到第一广播业务的应用层测量配置信息和第一广播业务对应的测量范围信息后，若当前不在第一广播业务对应的测量范围内，则可以先不对第一广播业务进行应用层测量，当进入第一广播业务对应的测量范围内，终端设备可以对第一广播业务进行应用层测量。也就是说，即使终端设备当前没在第一广播业务对应的测量范围内，接入网设备也可以向终端设备发送第一广播业务的应用层测量配置信息，从而当终端设备进入测量范围内时就可以进行应用层测量。
采用上述方法，从接入网设备的角度来看，接入网设备可以根据第二信息，有针对地向终端设备发送广播业务的应用层测量配置信息(即通过单播的方式发送)，便于接入网设备的灵活调控；从终端设备的角度来看：当终端设备对第一广播业务不感兴趣时，终端设备可以不向接入网设备发送第二信息，进而接入网设备也不再向该终端设备发送第一广播业务的应用层测量配置信息，相比于接入网设备以广播的方式发送第一广播业务的应用层测量配置(即使终端设备对第一广播业务不感兴趣，终端设备也需要去接收接入网设备广播的广播业务的应用层测量配置信息，)来说，可以避免终端设备执行不必要的接收，节省终端设备的功耗。
针对于上述实施例一，需要说明以下几点：
(1)上文中，终端设备确定终端设备感兴趣的广播业务的方式可以有多种，比如终端设备可以根据终端设备存储的应用层信息确定是否对广播业务(比如第一广播业务)感兴趣；其中，应用层信息比如包括用户服务订阅(user service description，USD)信息。示例性地，终端设备在判断是否对某个广播业务感兴趣时，也可以忽略USD中指示的广播业务开始传输的时间信息，也可以忽略目前协议中规定的发送广播业务兴趣信息所需的一些条件(例如SIB20/21是否存在、感兴趣的频点)。
终端设备确定即将接收或开始接收第一广播业务的数据的具体实现可以有多种。比如，终端设备的USD信息中可以包括第一广播业务开始传输的时间信息，进而终端设备可以根据该时间信息，确定出何时即将接收或开始接收第一广播业务的数据。又比如，终端设备也可以根据接入网设备的调度信息，确定即将接收或开始接收第一广播业务的数据。
(2)上文中，终端设备可以发起RRC建立过程或RRC恢复过程。为避免多个终端设备同时发起RRC建立过程或RRC恢复过程，导致接入网设备的负担较重，本申请实施例提供的一种解决方案为：在上述各种情形中，当终端设备确定需要发起RRC建立过程或RRC恢复过程时，终端设备可以生成一个随机数，若随机数大于或等于概率因子，则终端设备可以发起RRC建立过程或RRC恢复过程；若随机数小于概率因子，则终端设备可以先不发起RRC建立过程或RRC恢复过程，并开始等待，可选地，当终端设备的等待时间大于或等于回退时间时，终端设备可以发起RRC建立过程或RRC恢复过程。
示例性地，概率因子可以是接入网设备为终端设备配置的，或者也可以是协议预先定义的。回退时间可以是终端设备根据回退时间范围生成的，比如回退时间范围为[0,1](单位为毫秒)，则终端设备可以根据[0,1]随机生成一个回退时间，比如生成的回退时间为0.5毫秒，则当终端设备的等待时间大于或等于0.5毫秒时，终端设备可以发起RRC建立过程或RRC恢复过程。其中，回退时间范围可以是接入网设备为终端设备配置的，或者也可以是协议预先定义的。本申请实施例中以概率因子和/或回退时间范围是由接入网设备为终端设备配置的为例，比如接入网设备可以向终端设备发送第三信息(比如以广播的方式发送)，第三信息用于指示概率因子和/或回退时间范围；相应地，终端设备可以接收第三信息，并根据第三信息得到概率因子和/或回退时间范围。
本申请实施例提供的又一种解决方案为：接入网设备广播指示信息，以指示是否允许终端设备在当前小区由于接收广播业务的应用层测量配置信息而发起RRC建立过程或RRC恢复过程。比如，接入网设备在接入网设备的小区1广播指示信息1，指示信息1指示允许终端设备在小区1由于接收广播业务的应用层测量配置信息而发起RRC建立过程或RRC恢复过程；以及，接入网设备在接入网设备的小区2广播指示信息2，指示信息2指示不允许终端设备在小区2由于接收广播业务的应用层测量配置信息而发起RRC建立过程或RRC恢复过程。如此，通过灵活调整在不同小区广播的指示信息，可以避免大量终端设备同时发起RRC建立过程或RRC恢复过程。
(3)本申请实施例中是以基于管理的应用层测量为例，上述方法也可以适用于基于信令的应用层测量。在基于信令的应用层测量中，接入网设备可以向特定终端设备发送第一信息，相应地，特定终端设备根据第一信息，向接入网设备发送第二信息；进而，接入网设备根据第二信息，可以获知特定终端设备感兴趣的广播业务，并向特定终端设备发送特定终端设备感兴趣的广播业务的应用层测量配置信息。如此，接入网设备可以只向特性终端设备发送特定终端设备感兴趣的广播业务的应用层测量配置信息，而不发送不感兴趣的广播业务的应用层测量配置信息，便于节省传输资源的开销。
基于实施例一的描述，下面分别结合图4、图5和图6描述三种可能的实现流程。
图4为本申请实施例提供的通信方法所对应的流程示意图。如图4所示，该方法包括：
S401，接入网设备获取至少一个广播业务的应用层测量配置信息。
比如，接入网设备接收来自OAM网元的应用层测量请求消息，应用层测量请求消息包括至少一个广播业务的应用层测量配置信息。
S402，终端设备向接入网设备发送终端设备的能力信息，能力信息用于指示终端设备支持广播业务的应用层测量；相应地，接入网设备接收终端设备的能力信息。其中，终端设备处于连接态。
S403，接入网设备向终端设备发送第一信息，第一信息用于指示接入网设备具有至少一个广播业务的应用层测量配置信息；相应地，终端设备接收并保存第一信息。
示例性地，接入网设备根据终端设备的能力信息，确定终端设备支持广播业务的应用层测量后，可以通过RRC消息(比如RRC重配置消息)发送第一信息，第一信息可以包括至少一个广播业务的标识。
S404，接入网设备向终端设备发送RRC释放消息，以指示终端设备进入空闲态或非激活态；相应地，终端设备接收到RRC释放消息后，根据RRC释放消息进入空闲态或非激活态。
此处，终端设备从连接态进入空闲态或非激活态时，不释放第一信息，即仍然存储第一信息。
S405，终端设备确定即将接收或开始接收第一广播业务的数据或者对第一广播业务的数据感兴趣，且第一广播业务属于至少一个广播业务。

S407，终端设备向接入网设备发送终端设备的能力信息，能力信息用于指示终端设备支持广播业务的应用层测量的能力信息，能力信息用于指示终端设备支持广播业务的应用层测量。
可以理解的是，若终端设备是从空闲态进入连接态，由于终端设备进入空闲态时，接入网设备可以释放了终端设备的相关信息(比如能力信息)，因此，终端设备进入连接态后，可以向接入网设备发送终端设备的能力信息(即执行S407)。若终端设备是从非激活态进入空闲态，由于终端设备进入非激活态时，接入网设备可以不释放终端设备的相关信息(比如能力信息)，因此，终端设备进入连接态后，可以无需向接入网设备发送终端设备的能力信息(即不执行S407)。
S408，终端设备向接入网设备发送第二信息，第二信息用于指示终端设备对第一广播业务感兴趣。
此处，第二信息可以包括第一广播业务的标识，比如第二信息可以为MII。
S409，接入网设备接收第二信息，向终端设备发送第一广播业务的应用层测量配置信息。
可选的，接入网设备向终端设备发送第一广播业务的应用层测量配置信息时，还向终端设备发送第一广播业务的标识和/或该应用层测量配置信息对应的应用层测量标识。
S410，接入网设备向终端设备发送RRC释放消息，以指示终端设备进入空闲态或非激活态；相应地，终端设备接收到RRC释放消息后，根据RRC释放消息进入空闲态或非激活态。
S411，终端设备在空闲态或非激活态接收第一广播业务的数据，并根据第一广播业务的应用层测量配置信息，对第一广播业务进行应用层测量。
图5为本申请实施例提供的通信方法所对应的流程示意图。如图5所示，该方法包括：
S501，接入网设备获取至少一个广播业务的应用层测量配置信息。
S502，接入网设备发送第一信息，第一信息用于指示接入网设备具有至少一个广播业务的应用层测量配置信息；相应地，处于空闲态或非激活态的终端设备接收并保存第一信息。
S503，终端设备确定即将接收或开始接收第一广播业务的数据或者对第一广播业务的数据感兴趣，且第一广播业务属于至少一个广播业务。
S504，终端设备发起RRC建立过程或RRC恢复过程，以建立或恢复终端设备与接入网设备之间的RRC连接。
S505，终端设备向接入网设备发送终端设备的能力信息，能力信息用于指示终端设备支持广播业务的应用层测量的能力信息，能力信息用于指示终端设备支持广播业务的应用层测量。
S506，终端设备向接入网设备发送第二信息，第二信息用于指示终端设备对第一广播业务感兴趣。
此处，第二信息可以包括第一广播业务的标识，比如第二信息可以为MII。
S507，接入网设备接收第二信息，向终端设备发送第一广播业务的应用层测量配置信息。
S508，接入网设备向终端设备发送RRC释放消息，以指示终端设备进入空闲态或非激活态；相应地，终端设备接收到RRC释放消息后，根据RRC释放消息进入空闲态或非激活态。
S509，终端设备在空闲态或非激活态接收第一广播业务的数据，并根据第一广播业务的应用层测量配置信息，对第一广播业务进行应用层测量。
可选的，在S508和S509之前，终端设备也可以在连接态接收第一广播业务的数据，并对第一广播业务进行应用层测量。
图6为本申请实施例提供的通信方法所对应的流程示意图。如图6所示，该方法包括：
S601，接入网设备获取至少一个广播业务的应用层测量配置信息。
S602，终端设备向接入网设备发送终端设备的能力信息，能力信息用于指示终端设备支持广播业务的应用层测量；相应地，接入网设备接收终端设备的能力信息。其中，终端设备处于连接态。
S603，接入网设备向终端设备发送第一信息，第一信息用于指示接入网设备具有至少一个广播业务的应用层测量配置信息；相应地，终端设备接收并保存第一信息。
示例性地，接入网设备根据终端设备的能力信息，确定终端设备支持广播业务的应用层测量后，可以通过RRC消息(比如RRC重配置消息)发送第一信息，第一信息可以包括至少一个广播业务的标识。
S604，终端设备根据第一信息，若确定对至少一个广播业务中的第一广播业务感兴趣，则向接入网设备发送第二信息，第二信息用于指示终端设备对第一广播业务感兴趣。
此处，第二信息可以包括第一广播业务的标识。可以理解的是，此处的第二信息区别于MII，MII是在特定条件下发送的信息(比如当终端设备正在接收或即将接收广播业务的数据，终端设备才会发送MII)，而终端设备发送第二信息，可以无需考虑上述特定条件。
S605，接入网设备接收第二信息，向终端设备发送第一广播业务的应用层测量配置信息。
S606，接入网设备向终端设备发送RRC释放消息，以指示终端设备进入空闲态或非激活态；相应地，终端设备接收到RRC释放消息后，根据RRC释放消息进入空闲态或非激活态。
S607，终端设备在空闲态或非激活态接收第一广播业务的数据，并根据第一广播业务的应用层测量配置信息，对第一广播业务进行应用层测量。
可选的，在S606和S607之前，终端设备也可以在连接态接收第一广播业务的数据，并对第一广播业务进行应用层测量。
可以理解的是，上述图4至图6中，各个步骤的具体实现可以参照实施例一中的描述。上述侧重描 述了图4至图6的区别之处，除区别之外的其它内容，可以相互参照。
实施例二
上述实施例一中，接入网设备是通过单播的方式向终端设备发送广播业务的应用层测量配置信息。在实施例二中，接入网设备可以通过广播的方式向终端设备发送广播业务的应用层测量配置信息，下面结合图7和图8描述两种可能的实现流程。
图7为本申请实施例二提供的通信方法所对应的一种流程示意图。如图7所示，该方法包括：
S701，接入网设备发送第一信息；相应地，终端设备可以接收第一信息。
比如，接入网设备可以通过广播的方式发送第一信息。第一信息可以包括至少一个广播业务的应用层测量配置信息，至少一个广播业务包括第一广播业务。区别于实施例一，实施例一的第一信息不包括至少一个广播业务的应用层测量配置信息。
S702，终端设备根据第一信息，向接入网设备发送第二信息，第二信息用于指示终端设备对广播业务感兴趣，比如第二信息用于指示终端设备对第一广播业务感兴趣。
此处，终端设备向接入网设备发送第二信息的实现可以参照实施例一。与实施例一的区别在于：若终端设备是通过RRC建立请求消息或RRC恢复请求消息发送第二信息，则接入网设备接收到第二信息后，可以获知终端设备建立或恢复RRC连接的目的是为了向接入网设备发送第二信息，进而可以拒绝建立或恢复RRC连接，以便降低接入网设备的负担。
如此，接入网设备根据终端设备上报的第二信息，可以获知终端设备对第一广播业务感兴趣，即终端设备可以对第一广播业务执行应用层测量，从而便于接入网设备的调控。例如，当接入网设备获知对第一广播业务执行应用层测量的终端设备的数量达到一定门限之后，接入网设备可以停止广播第一广播业务的应用层测量配置信息；或者，接入网设备接收到第二信息之后，向OAM网元发送指示信息，指示终端设备对第一广播业务感兴趣，从而OAM网元能获知对第一广播业务执行应用层测量的终端设备。当对第一广播业务执行应用层测量的终端设备的数量达到一定门限之后，OAM网元可以向接入网设备发送释放第一广播业务的应用层测量的消息，进而接入网设备可以停止广播第一广播业务的应用层测量配置信息。
图8为本申请实施例二提供的通信方法所对应的又一种流程示意图。如图8所示，该方法包括：
S801，接入网设备发送第一信息，第一信息用于触发终端设备上报第二信息；相应地，终端设备可以接收第一信息。
比如，第一信息用于指示接入网设备具有至少一个广播业务的应用层测量配置信息。
此处，接入网设备发送第一信息的具体实现参照实施例一。
S802，终端设备根据第一信息，向接入网设备发送第二信息，第二信息用于指示终端设备对广播业务感兴趣，比如第二信息用于指示终端设备对第一广播业务感兴趣。
此处，终端设备向接入网设备发送第二信息的具体实现可以参照S702。
S803，接入网设备发送至少一个广播业务的应用层测量配置信息；相应地，终端设备接收至少一个广播业务的应用层测量配置信息。
本申请实施例中，对S801和S803的执行顺序可以不做限定。
示例性地，接入网设备可以通过广播的方式发送至少一个广播业务的应用层测量配置信息。终端设备接收到至少一个广播业务的应用层测量配置信息，若对第一广播业务感兴趣，则后续可以根据第一广播业务的应用层测量配置信息，对第一广播业务进行应用层测量。
如此，接入网设备根据终端设备上报的第二信息，可以获知终端设备对第一广播业务感兴趣，即终端设备可以对第一广播业务执行应用层测量，从而便于接入网设备的调控。
实施例三
上述实施例一或实施例二中，对接入网设备向终端设备发送第一广播业务的应用层测量配置信息的实现进行了描述。在实施例三中，将主要针对终端设备向接入网设备上报第一广播业务的应用层测量结果的相关实现进行研究。
图9为本申请实施例提供的通信方法所对应的流程示意图。如图9所示，该方法包括：
S901，第一接入网设备向终端设备发送第一广播业务的应用层测量配置信息；相应地，终端设备 接收第一广播业务的应用层测量配置信息。
示例性地，S901的具体实现可以参照实施例一中的描述。
可选地，第一接入网设备除向终端设备发送第一广播业务的应用层测量配置信息之外，还可以向终端设备(即终端设备的AS层)发送QoE reference、应用层测量标识，以及进一步可选地，还可以向终端设备发送(即终端设备的AS层)MCE的标识。其中，如前文所述，QoE reference和应用层测量标识之间存在对应关系。针对于同一应用层测量(或者说同一QoE reference)，第一接入网设备为不同终端设备分配的应用层测量标识可以不同。
MCE的标识可以与MCE的地址信息之间存在对应关系。接入网设备向终端设备发送MCE的标识，而不是发送MCE的地址信息，可以有效避免接入网设备向终端设备发送MCE的地址信息而导致的安全问题。示例性地，OAM网元可以为每个MCE的地址信息分配了一个MCE的标识，并将MCE的地址信息和MCE的标识之间的对应关系通知给接入网设备，进而当终端设备上报的应用层测量结果携带MCE的标识时，接入网设备便可以知晓该应用层测量结果对应的MCE的地址信息。
可选地，终端设备的AS层可以把QoE reference和应用层测量标识发送给终端设备的AS层的上层。
可选地，终端设备的AS层可以保存QoE reference和应用层测量标识之间的对应关系。
S902，终端设备对第一广播业务进行应用层测量。
此处，当终端设备开始接收第一广播业务的数据时，终端设备可以启动第一广播业务的应用层测量。其中，终端设备可以在空闲态或非激活态或连接态接收第一广播业务的数据。
S903，终端设备向第二接入网设备发送第一广播业务的应用层测量结果。
示例性地，终端设备可以在接入第二接入网设备后，向第二接入网设备发送第一广播业务的应用层测量结果。
比如一种可能的场景为：S901中，终端设备在连接态接收到第一接入网设备发送的第一广播业务的应用层测量配置信息后，进入空闲态；在S902中，终端设备在空闲态接收第一广播业务的数据，以及对第一广播业务进行应用层测量；在S903中，终端设备接入第二接入网设备，并向第二接入网设备发送第一广播业务的应用层测量结果。
其中，第二接入网设备和第一接入网设备可以是同一个接入网设备，此种情形下，终端设备进入空闲态时，第一接入网设备释放了终端设备的相关信息，比如释放了QoE reference和为该终端设备分配的应用层测量标识之间的对应关系；或者，第二接入网设备和第一接入网设备也可以是不同接入网设备，此种情形下，第二接入网设备中没有终端设备的相关信息，比如QoE reference和为该终端设备分配的应用层测量标识之间的对应关系(比如终端设备在空闲态下从第一接入网设备的覆盖范围移动至第二接入网设备的覆盖范围，并接入第二接入网设备，因此，第二接入网设备中没有终端设备的相关信息)。
针对于该种场景，终端设备向第二接入网设备第一次上报第一广播业务的应用层测量结果时，可以携带第一广播业务的应用层测量配置信息对应的QoE reference和应用层测量标识；相应地，第二接入网设备可以保存QoE reference和应用层测量标识之间的对应关系。之后，终端设备再向第二接入网设备上报第一广播业务的应用层测量结果时，可以携带对应的应用层测量标识，而无需携带对应的QoE reference。需要说明的是，QoE reference、应用层测量标识是针对一个应用层测量配置信息的，如果该应用层测量信息用于多个广播业务，则QoE reference、应用层测量标识对于这些广播业务的应用层测量结果都是相同的。这种情况下，之后，终端设备在后续上报这些广播业务中除第一广播业务之外的其他业务的应用层测量结果时，可以携带对应的应用层测量标识，而无需携带对应的QoE reference。
可选地，终端设备向第二接入网设备第一次上报第一广播业务的应用层测量结果时，还可以携带对应的MCE的标识；相应地，第二接入网设备可以保存MCE的标识。之后，终端设备再向第二接入网设备上报第一广播业务的应用层测量结果时，可以无需携带对应的MCE的标识。如果该应用层测量配置信息用于多个广播业务，之后，终端设备在上报这些广播业务中除第一广播业务之外的其他业务的应用层测量结果时，可以携带对应的应用层测量标识，而无需携带对应的MCE的标识。
可选的，第二接入网设备还可以向终端设备发送指示信息，指示终端设备在第一次上报广播业务的应用层测量结果之后，终端设备再次上报该应用层测量的测量结果是否携带QoE reference和/或MCE的标识。如果指示信息指示终端设备无需携带，则终端设备在第一次上报广播业务的应用层测量结果之后，终端设备再次上报该应用层测量的测量结果时无需携带QoE reference和/或MCE的标识；否则终端设备需要携带。
S904，终端设备从第二接入网设备切换至第三接入网设备时，第二接入网设备向第三接入网设备发送针对该终端设备的QoE reference和应用层测量标识之间的对应关系。
可选地，第二接入网设备还可以向第三接入网设备发送针对该终端设备的应用层测量(即上面QoE reference所标识的应用层测量)对应的MCE的地址信息或MCE ID。
S905，终端设备向第三接入网设备发送第一广播业务的应用层测量结果。
此处，终端设备向第三接入网设备发送第一广播业务的应用层测量结果时，可以只需携带应用层测量标识，而无需携带QoE reference。第三接入网设备从终端设备接收到应用层测量标识之后，根据第二接入网设备发送的QoE reference和应用层测量标识之间的对应关系，可以获知该应用层测量结果对应的QoE reference，从而第三接入网设备可以把QoE reference和应用层测量结果发送给该应用层测量对应的MCE。
可选地，终端设备向第三接入网设备发送第一广播业务的应用层测量结果时，还可以无需携带该应用层测量对应的MCE的标识。第三接入网设备从终端设备收到应用层测量标识之后，根据第二接入网设备发送的MCE的标识或MCE的地址信息和应用层测量标识，可以获知该应用层测量结果对应的MCE的标识或MCE的地址信息，进而便可知道应该把该应用层测量结果发送给哪一个MCE。如果该应用层测量信息用于多个广播业务，则终端设备在上报这些广播业务中除第一广播业务之外的其他业务的应用层测量结果时，可以携带对应的应用层测量标识，而无需携带对应的QoE reference和MCE的标识。
其中，S904和S905是可选的步骤。
也就是说，在终端设备从空闲态进入连接态后，第一次向接入网设备上报广播业务的应用层测量结果时，可以携带QoE reference和应用层测量标识，而后续再上报时可以无需携带QoE reference(可选地，还可以无需携带MCE的标识)。如此，由于QoE reference是全球唯一的，占用的比特数量较大(比如QoE reference可能占用6个字节，MCE的标识可能占用1个字节)，从而可以有效减少上报广播业务的应用层测量结果的资源开销。
可以理解的是，若终端设备在连接态接收到第一接入网设备发送的第一广播业务的应用层测量配置信息后，后续一直处于连接态(即在连接态接收第一广播业务的数据，以及对第一广播业务进行应用层测量)或者非激活态(即未进入过空闲态)，则终端设备每次向接入网设备上报广播业务的应用层测量结果时，都可以无需携带QoE reference(可选地，还可以无需携带MCE的标识)。
针对于上述实施例一至实施例三，可以理解的是：
(1)上述侧重描述了实施例一至实施例三中不同实施例之间的差异之处，除差异之处的其它内容，实施例一至实施例三之间可以相互参照；此外，同一实施例中，不同实现方式或不同示例之间也可以相互参照。
(2)实施例一至实施例三所描述的各个流程图的步骤编号仅为执行流程的一种示例，并不构成对步骤执行的先后顺序的限制，本申请实施例中相互之间没有时序依赖关系的步骤之间没有严格的执行顺序。各个流程图中所示意的步骤并非全部是必须执行的步骤，可以根据实际需要在各个流程图的基础上删除部分步骤，或者也可以根据实际需要在各个流程图的基础上增添其它可能的步骤。
