需要说明的是，本申请所涉及的信息(包括但不限于用户设备信息、用户个人信息等)、数据(包括但不限于用于分析的数据、存储的数据、展示的数据等)以及信号，均为经用户授权或者经过各方充分授权的，且相关数据的收集、使用和处理需要遵守相关国家和地区的相关法律法规和标准。
下面，对本申请的应用场景进行说明：
图1示出了本申请一个示例性实施例提供的通信系统的框图，该通信系统可以包括：终端10、接入网设备20和核心网设备30。
终端10的数量通常为多个，每一个接入网设备20所管理的小区内可以分布一个或多个终端10。终端10可以包括各种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，以及各种形式的用户设备(User Equipment，UE)、移动台(Mobile Station，MS)等等。为方便描述，本申请实施例中，上面提到的设备统称为终端。
接入网设备20是一种部署在接入网中用以为终端10提供无线通信功能的装置。为方便描述，本申请实施例中，上述为终端10提供无线通信功能的装置统称为网络设备。网络设备20与终端10之间可以通过空口建立连接，从而通过该连接进行通信，包括信令和数据的交互。网络设备20的数量可以有多个，两个邻近的网络设备20之间也可以通过有线或者无线的方式进行通信。终端10可以在不同的网络设备20之间进行切换，也即与不同的网络设备20建立连接。
该网络设备20可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备网络设备功能的设备的名称可能会有所不同，例如在5G NR(New Radio，新空口)系统中，称为gNodeB或者gNB。随着通信技术的演进，“网络设备”这一名称可能会变化。
核心网设备30是部署在核心网中的设备，核心网设备30的功能主要是提供用户连接、对用户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。核心网设备30包括各种具有各种管理功能的核心网网元。例如，该核心网网元包括AMF(Access and Mobility Management Function，接入及移动性管理功能)网元、SMF(Session Management Function，会话管理功能)网元、PCF(Policy Control Function，策略控制功能)网元、UPF(User Plane Function，用户平面功能)网元、NSSF(The Network Slice Selection Function，网络切片选择功能)网元、AUSF(Authentication Server Function，鉴权服务器功能)网元、UDM(Unified Data Management，统一数据管理)网元、AF(Application Function，应用功能)网元、NEF(Network Exposure Funcition，网络能力开放功能)网元等。
在一些实施例中，终端涉及多种类型的业务。例如，移动媒体类服务、云AR(Augmented Reality，增强现实)或云VR(Virtual Reality，虚拟现实)业务、云游戏、基于视频的机器与无人机远程控制等业务。其中，终端涉及的业务包括多模态数据流。其中，该多模态数据是指同一业务或应用从同一个设备或不同设备输入的数据，并且这些数据可以输出到一个或多个目的设备。另外，多模态数据中的各数据流具有一定的相关性，也就是多条数据流之间可以互相影响。例如，音频和视频流的同步，触觉和视觉的同步等。这类媒体业务的数据流本身，各数据流之间，以及这些数据流对网络传输的需求，都存在一些共性特征，这些特性的有效识别和利用将更有助于网络和业务的传输、控制，也更有助于业务保障和用户体验。
可选地，本申请中的业务可以统称为XRM(Extended Reality and Media services，扩展现实和媒体服务)业务，在移动通信系统中考虑数据流之间的相关性。
在本申请实施例中，终端与通过云服务器交互业务数据，并且云服务器与AF网元传输数据流，而对于AF网元来说，该AF网元与NEF网元交互以保证数据流之间的相关性。
在一些实施例中，本申请实施例涉及第一网元、第二网元和第三网元，该第一网元可以与第二网元和第三网元进行交互，也可以理解为，该第一网元是第二网元与第三网元之间媒介。又或者，第二网元与第三网元之间也可以直接进行交互。
可选地，该第一网元为NEF网元，该第二网元为AF网元，该第三网元为PCF网元。
图2示出了本申请一个示例性实施例提供的时延差信息报告方法的流程图，示例性的可以应用于如图1所示的核心网设备包括的网元中，该方法包括以下内容中的至少部分内容：
步骤201：第二网元向第一网元发送订阅请求，订阅请求用于请求订阅的业务的数据流的时延差信息。
步骤202：第一网元接收第二网元发送的订阅请求。

在本申请实施例中，第二网元与终端之间传输有业务的数据流，并且第二网元可以通过订阅传输的业务的数据流的时延差信息，以便于确定传输的业务的数据流之间的关系。
在一些实施例中，该订阅请求也可以理解为请求订阅的业务的数据流相关的时延差信息。或者，该订阅请求也可以理解为请求订阅的业务的数据流对应的时延差信息。
则第二网元向第一网元发送订阅请求，通过该订阅请求即可订阅业务的数据流的时延差信息，而对于第一网元来说，该第一网元接收到该订阅请求后，即可确定第二网元需要订阅的业务的数据流的时延差信息。
其中，对于任两条数据流来说，每条数据流均对应一个时延，而两条数据流之间的时延的差值可以理解为时延差。例如，该时延差为2ms(毫秒)、3ms或者其他数值，本申请实施例不做限定。
在一些实施例中，每条数据流对应的时延是指该数据流由发送端传输到接收端所需耗费的时长。
可选地，时延差信息对应的时延差包括多种类型的时延差。例如，该时延差包括以下至少一项：
(1)平均时延差。
其中，该平均时延差是指多个时延差的平均值。例如，在确定多条数据流的时延差后，对确定的多条数据流的多个时延差求平均值，以得到平均时延差。
例如，若获取的时延差包括时延差1、时延差2和时延差3，则获取时延差1、时延差2和时延差3的平均值，作为平均时延差。
(2)最大时延差。
其中，该最大时延差是指多个时延差中最大的时延差。例如，在确定多条数据流的时延差后，对确定的多条数据流的多个时延差进行对比，以得到多个时延差中数值最大的时延差，作为最大时延差。
例如，若获取的时延差包括时延差1、时延差2和时延差3，则对比时延差1、时延差2和时延差3的数值，如时延差1大于时延差2，时延差2大于时延差3，则将时延差1作为最大时延差。
(3)最小时延差。
其中，该最小时延差是指多个时延差中最小的时延差。例如，在确定多条数据流的时延差后，对确定的多条数据流的多个时延差进行对比，以得到多个时延差中数值最小的时延差，作为最小时延差。
例如，若获取的时延差包括时延差1、时延差2和时延差3，则对比时延差1、时延差2和时延差3的数值，如时延差1小于时延差2，时延差2小于时延差3，则将时延差1作为最小时延差。
(4)时延差范围。
其中，时延差范围是指时延差所属的范围。例如，该时延差范围为2ms到5ms，或者，该时延差范围为5ms到15ms，本申请实施例不做限定。
步骤204：第三网元接收第一网元发送的订阅请求，订阅请求用于请求订阅的业务的数据流的时延差信息。
在本申请实施例中，第三网元可以接收第一网元发送的订阅请求，进而确定第二网元所订阅的信息，进而由第三网元对第二网元所订阅的信息进行监控。
步骤205：第三网元响应于订阅请求，向第一网元发送报告信息。
在一些实施例中，第三网元接收到订阅请求后，则可以确定第二网元所订阅的数据流，而第三网元触发所请求订阅的数据流的监控，进而获取数据流的报告信息。
步骤206：第一网元接收第三网元响应于订阅请求发送的报告信息。
在本申请实施例中，第三网元接收该订阅请求后，则可以根据该订阅请求 确定该订阅请求对应的报告信息，进而向第一网元发送报告信息。
其中，该报告信息包括订阅的业务的数据流的时延。
步骤207：第一网元向第二网元发送时延差信息，时延差信息基于报告信息确定。
步骤208：第二网元接收第一网元发送的时延差信息，时延差信息基于报告信息确定，报告信息由第三网元响应于订阅请求报告。
在本申请实施例中，第一网元接收第三网元发送的报告信息后，则可以基于接收的报告信息确定时延差信息，进而将确定的时延差信息发送给第二网元，由第二网元接收第一网元发送的时延差信息。
需要说明的是，本申请实施例是以第二网元通过订阅请求订阅数据流的时延差信息为例进行说明。而在另一实施例中，第二网元还可以通过订阅请求订阅数据流的时延信息，以使第一网元报告数据流的时延信息，又或者，第二网元还可以通过订阅请求订阅数据流的时延信息以及时延差信息，以使第一网元报告数据流的时延信息以及时延差信息。
需要说明的是，网络设备所执行的步骤可以单独形成一个实施例，终端所执行的步骤也可以单独形成一个实施例，本申请对此不作限定。

在图2所示的实施例的基础上，第一网元需要确定第三网元，进而向确定的第三网元发送订阅请求。在本申请实施例中，第一网元可以通过两种方式确定第三网元。
第一种：第一网元基于订阅请求，确定至少一个第三网元，向每个第三网元发送订阅请求。
在本申请实施例中，第一网元接收到订阅请求后，可以根据该订阅请求确定至少一个第三网元，进而可以向确定的第三网元发送订阅请求，以便于第三网元返回订阅请求对应的报告信息。
可选地，第一网元可以采用以下任一种方式来确定第三网元。

其中，该配置信息为第一网元在本地存储的配置。并且该配置信息包括订阅请求所订阅的时间对应的第三网元。则第一网元接收到订阅请求后，可以根据该订阅请求和配置信息确定至少一个第三网元。
本申请实施例提供的方案中，第一网元接收到订阅请求后，根据网络存储功能或自身的配置信息即可确定至少一个第三网元，进而将订阅请求发送给已确定的至少一个第三网元，不仅扩展了确定的第三网元的方式，而且提高了发送订阅请求的准确性。
第二种：第一网元基于订阅请求，向缺省第三网元发送订阅请求。
在本申请实施例中，缺省第三网元用于将订阅请求转发给其他第三网元。也就是说，缺省第三网元接收到第一网元发送的订阅请求后，可以将接收的订阅请求转发给其他第三网元。
其中，该缺省第三网元为第一网元传输订阅请求的网元，该缺省第三网元接收订阅请求后，还可以将接收的订阅请求转发给其他第三网元。也可以理解为，该缺省第三网元为中转网元，具有转发功能。该缺省第三网元为通过通信协议约定的网元，或者，为预配置的网元，或者为默认的网元，或者为采用其他方式确定的网元，本申请实施例不做限定。

在本申请实施例中，第一网元对多个报告信息进行汇聚，得到时延差信息，向第二网元发送时延差信息。
在本申请实施例中，第三网元向第一网元发送报告信息后，实际上多条报告信息对应不同的数据流的时延，则第一网元接收到多条报告信息后，需要对这多条报告信息进行处理，以得到第二网元订阅的时延差信息，进而将得到的时延差信息发送给第二网元。
在一些实施例中，报告信息中包括时延，则第一网元执行以下步骤对报告信息进行汇聚。
第一网元根据多个第三网元中每个第三网元发送的时延，确定业务的数据流之间的时延差，向第二网元发送时延和/或时延差。
在本申请实施例中，第三网元可以根据订阅请求以获取数据流的时延，进而由多个第三网元分别向第一网元发送时延，则第一网元可以接收多个第三网元中每个第三网元发送的时延，再由第一网元根据接收的多个第三网元中每个第三网元发送的时延，确定业务的数据流之间的时延差，进而由第一网元向第二网元发送数据流的时延和/或时延差。
在一些实施例中，订阅请求指示订阅数据流的时延差，则对于第一网元来说，该第一网元向第二网元发送已确定的数据流的时延差即可。
在本申请实施例中，若订阅请求指示订阅数据流的时延差，则对于第一网 元来说，根据订阅请求确定第二网元请求订阅的数据流之间的时延差，在确定数据流之间的时延差后向第二网元发送确定的数据流之间的时延差。

事件过滤器参数定义了S-NSSAI(在可信AF或不可信AF的AF-Service-Identifier的情况下)、S-NSSAI和DNN、XRM服务组ID、终端ID，为其请求XRM服务订阅。
事件报告信息参数定义了报告模式，包括阈值或带有周期性时间间隔的定期报告，如果请求，则立即报告标志。
当订阅的多模式数据流的延迟差异达到阈值时，才会发送与基于阈值的订 阅相关的通知。每次从低于阈值变为达到阈值时，都会发送一个通知。
2、NEF发送Nnef_EventExposure Subscribe/UnsubscribeResponse(响应消息)给AF。
3、NEF发现负责请求的事件过滤器参数的PCF，并授权AF请求。
例如，S-NSSAI和服务ID，或S-NSSAI和服务组ID，或S-NSSAI和DNN和服务ID，或S-NSSAI和DNN和服务组ID；服务组内的S-NSSAI和终端ID，或服务组内的S-NSSAI和终端ID，或服务组内的S-NSSAI和DNN和终端ID，或服务组内的S-NSSAI和DNN和终端ID服务组。
NEF可以查询NRF以找到负责请求的事件过滤器参数的PCF。如果需要，NEF在执行查询之前将AF-Service-Identifier转换为相应的S-NSSAI。
4、NEF向PCF发送Npcf_PolicyAuthorization_Subscribe Request(事件请求消息)。
如果NEF还没有从PCF为所请求的事件过滤器订阅事件，则NEF向支持所请求的两个流的所有PCF发起请求Npcf_PolicyAuthorization_Subscribe Request。
其中，Npcf_PolicyAuthorization_Subscribe Request包括事件ID、事件过滤器、事件报告信息、立即报告、S-NSSAI。
NEF存储AF请求的事件报告信息。如果为所请求的几个数据流选择了多个PCF，则NEF可以在其对PCF的请求中将事件报告信息设置为周期性。如果选择单个PCF，则NEF将事件报告信息设置为与收到的来自AF的请求相同。NEF还将事件ID和事件过滤器设置为与收到的来自AF的请求相同。(所选择的周期由NEF根据其内部逻辑或AF请求选择)
5、PCF用Npcf_PolicyAuthorization_SubscribeResponse(事件响应消息)消息向NEF确认。
6、PCF进行策略决策和订阅事件。
PCF做出策略决定并订阅AF或NEF请求的事件，为了订阅请求的5G延时差，PCF可能会触发对特定数据流对的QoS监控，以获得端到端延时，并计算延时差。
例如，PCF向SMF发起SM策略关联修改请求。根据来自PCF的用于测量的QoS监控策略，SMF为UPF和RAN(如果需要)生成QoS监控配置。
7、事件触发或通知报告给PCF。
其中，当检测到/达到事件时，将触发报告，例如达到阈值，或周期计时器超时。
例如UPF触发报告消息将测量的信息(端到端延时，延时差)报告给PCF。
如果PCF被告知所请求的5G延时差，PCF可以将此类信息发送给NEF。如果PCF发现延时差大于AF提供的延时差阈值，PCF可以将此信息通知给NEF，以及这对流的实时延时值。
基于该通知，PCF可以为一对流中的一个或每个流调整相关的PCC(Policy Control and Charging，策略控制和计费)规则，例如降级或升级相关的QoS(Quality of Service，服务质量)授权。
8、PCF向NEF发送Npcf_PolicyAuthorization_NotifyRequest(策略授权通知)消息。
其中，Npcf_PolicyAuthorization_NotifyRequest包括事件ID、事件过滤器、事件报告信息。
如果订阅是针对基于事件的通知(例如，基于监控的事件达到阈值)，则事件报告信息参数包含对事件完成的确认。
如果订阅是定期通知或即时报告，则事件报告信息参数提供当前延时和延时差的信息(例如延时差值，或以最大延时差的百分比表示)
9、NEF向PCF发送Npcf_PolicyAuthorization_NotifyResponse(策略授权响应)消息。
10、当发现过程返回单个PCF时，从PCF收到通知后NEF立即返回。
在不信任的AF的情况下，NEF在返回的通知中包含与S-NSSAI对应的AF-Service-Identifier。
11a、当为请求的延时差选择多个PCF时，NEF从报告PCF执行聚合。
只要订阅处于活动状态，NEF就会维护所选PCF的特定流对(例如，包括实时端到端延时和延时差)的整体计算。如果为这对流的请求延时差选择了多个PCF，则NEF会不断更新聚合信息以能够满足来自AF的传入订阅请求。
11b、当为请求的流对的延时差选择多个PCF时，当AF订阅事件的报告条件满足时，NEF触发向AF的通知。
在不信任的AF的情况下，NEF在返回的通知中包含与S-NSSAI对应的AF-Service-Identifier。
