具体实施方式

在通信场景中，用户所使用的应用层业务是由运营商自身的应用功能节点或者是第三方的应用功能节点提供的。
当前网络能力开放功能可以为运营商自己或者是第三方的应用功能节点，提供该应用功能节点AF所对应的应用的用户面的信息。举例而言，应用功能节点AF可以向信息提供网元SMF订阅指定一个或者多个用户的用户面管理相关的信息，例如DNAI和N6路由信息的变更；然后应用功能节点AF可以根据收到的信息，向网络PCF发送相应的策略或者调度请求，以优化业务体验。
但是，在相关技术中，目前应用功能节点AF无法向网络订阅其他应用功能节点的相关信息。一般应用与应用之间，只能通过应用层的相互交互，来确定业务是否运行或获取其他信息。例如，运营商想开发相关的短信增值服务，即当监测到用户在使用某第三方应用时，运营商的短信系统可以向该用户推送相关的增值短信。但是该功能无法通过网络实现。

接下来，参考图2中所示对本公开实施例中的信息传输方法进行具体说明。
在步骤S210中，应用功能节点发送针对其他应用功能节点提供的目标应用的订阅请求，并获取所述订阅请求对应的目标信息。
本公开实施例中，应用功能节点与3GPP核心网络交互以提供服务，可以允许运营商信任的应用功能直接与相关网络功能交互。应用功能节点可以为运营商自己或者是第三方的应用功能节点。应用功能节点能够提供用户所使用的应用层业务，可以为任意一个应用功能节点，例如运营商的IMS系统(IP Multimedia Subsystem，IP多媒体子系统)，也可以为其他系统，此处不作限定。每个应用都可存在对应的应用功能节点，且一个应用功能节点可以提供一个或多个应用。
目标应用可以为其他应用功能节点提供的应用，其他应用功能节点与应用功能节点不同。目标应用可以为其他应用功能节点提供的多个应用中的任意一个或多个，具体根据实际业务需求而确定。多个目标应用可以由相同应用功能节点提供，也可以由不同应用功能节点提供，此处不作限定。举例而言，应用功能节点1为运营商的IMS系统中的短信系统，目标应用可以为与运营商的IMS系统代表的应用功能节点1不同的其他应用功能节点2所提供的应用，其他应用功能节点提供的应用可以包括应用1、应用2、应用2等等，目标应用可以为应用1。即，运营商IMS系统中的短信系统，可以订阅其他应用功能节点2对应的应用1的使用情况。
订阅请求可以为针对于目标用户以及目标应用的信息请求，订阅请求用于获取目标用户在使用其他应用功能节点所提供的目标应用时的相关信息，相关信息用于描述对目标应用的使用情况或者是目标应用的状态信息等。目标用户可以为某一个用户或者是用户组中的用户，此处不作限定。在一些实施例中，订阅请求可以包括但不限于以下信息：用户信息、应用状态以及其他可选条件。其中，用户信息指的是目标用户(或目标用户组)ID，目标应用ID或目标服务提供商ID。应用状态指的是目标应用对应的目标报告信息或者事件，例如目标应用的开始/结束通知、目标应用流量大小等等。其他可选条件包括但不限于针对于目标应用的目标服务器地址、网络服务区域、订阅时长或有效性信息、报告阀值；其中，订阅时长用于代表订阅请求的有效时长，报告阀值用于描述目标报告信息或事件的 触发条件，若超过报告阀值，则触发目标报告信息进行报告。报告阀值例如可以为流量阀值或者是使用时长阀值等等。举例而言，报告阀值可以为流量总量大于500M的流量或者时长超过一个小时。
在应用功能节点发送针对其他应用功能节点提供的目标应用的订阅请求时，应用功能节点可以直接将订阅请求发送至用户数据库，也可先发送至网络开放功能节点，再由网络开放功能节点发送至用户数据库。具体根据应用功能节点的类型而确定。应用功能节点的类型可以根据其来源而确定，例如可以包括第一类型网元和第二类型网元。其中，第一类型网元可以为第三方部署网元，第二类型网元为运营商自身部署的网元。
图3中示意性示出了发送订阅请求的流程图，参考图3中所示，主要包括以下步骤：
在步骤S310中，若所述应用功能节点为第一类型网元，应用功能节点通过网络开放功能节点将所述订阅请求发送至用户数据库；
在步骤S320中，若所述应用功能节点为第二类型网元，应用功能节点将所述订阅请求发送至用户数据库。
本公开实施例中，首先对应用功能节点的类型为第一类型网元时的发送订阅请求的过程进行说明。应用功能节点发送针对目标应用的订阅请求包括：应用功能节点将针对其他应用功能节点提供的目标应用的订阅请求发送至网络开放功能节点，网络开放功能节点发送至用户数据库。应用功能节点生成面向目标应用的信息订阅请求。进一步，可以将针对于目标用户在目标应用的订阅请求发送至网络中的网络开放功能节点。网络可以为5GC网络，但本公开实施例中的网络不局限于此。需要说明的是，在3GPP标准TS23.501/502/503中，网络开放功能节点NEF(Network Exposure Function)位于5G核心网和外部第三方应用功能体之间(可能也有部分内部AF)，负责管理对外开放网络数据的，所有的外部应用，想要访问5G核心网内部数据，都必须要通过NEF。NEF提供相应的安全保障来保证外部应用到3gpp网络的安全，提供外部应用QoS定制能力开放、移动性状态事件订阅、AF请求分发等功能。NEF使用标准化接口(Nudr)将信息作为结构化数据存储到统一数据存储库。网络开放功能从其他网络功能接收信息(基于其他网络功能的公开功能)。所存储的信息可以由NEF访问并“重新开放”到其他网络功能和应用功能，并用于其他目的，例如分析。
在本公开实施例中，网络开放功能节点可以根据应用功能节点的类型对接收到的订阅请求中的信息进行转换操作。若所述应用功能节点为第一类型网元，网络开放功能节点NEF会对接收到的信息进行转换操作，转换操作可以包括转换/翻译。具体地，可以按照网络中的参数信息对接收到的订阅请求中的信息进行格式转换，例如对目标用户(或目标用户组)ID，应用ID、用户信息等进行格式转换，以使其满足网络的参数格式。举例而言，第一类型网元的订阅请求中的信息为电话号码，在网络里用的是网络标识号，因此需要将电话号码转换为网络标识号。通过转换操作，可以满足网络安全隔离的需要，提高安全性。若所述应用功能节点为第二类型网元，可以不对接收到的订阅请求中的信息进行转换操作，即保持订阅请求中的信息不变。
在对订阅请求中的信息进行转换操作后，网络开放功能节点可以将来自应用功能节点的订阅请求发送至用户数据库UDR(Unified Data Repository)，以在用户数据库中对所述应用功能节点与所述目标应用的报告事件进行关联，并存储至所述用户数据库。
接下来对应用功能节点的类型为第二类型网元时的发送订阅请求的过程进行说明。若应用功能节点的类型为运营商自身部署的网元，则应用功能节点直接将订阅请求发送至用户数据库即可。
用户数据库中可以包含目标用户的所有信息，例如报告信息、使用信息等等。举例而言，用户数据库中可以包含用于表示用户只能在某些地方使用某些服务的信息、用于表示使用某个应用时应该向网络报告相关情况的信息。
在用户数据库中，可以修改目标用户的签约信息中与目标应用对应的相关信息。签约信息可以包括但不限于：用户等级、用户的基本流量、对特定应用分配的QoS(Quality of Service，服务质量)的标准、目标应用对应的相关信息。用于修改的相关信息可以为签约信息中的一部分，例如可以为使用某个应用时需要报告的报告信息，包括但不限于使用某个应用时对应的路由。
在对签约信息中与目标应用对应的相关信息进行调整后，可以将应用功能节点与目标应用的报告事件进行关联。此处的关联可以通过绑定来实现。基于此，可以为应用功能节点和目标应用的报告事件之间建立关联关系，进一步可以将应用功能节点与目标用户、订阅请求对应的目标应用的报告事件进行关联，使得应用功能节点能够与目标用户在使用目标应用时的目标应用的报告事件相关联，且目标应用的报告事件与接收到的订阅请求相对应。举例而言，应用功能节点有可能同时请求多个用户，因此需要找出目标用户并将该目标用户使用目标应用时需要报告的信息(目标应用的报告事件)填入应用功能节点，从而实现多个信息之间的绑定，并且可以将绑定好的信息存储在用户数据库。基于此，用户数据库中可以存储订阅请求、目标用户、目标应用的报告事件以及应用功能节点之间绑定得到的绑定信息。
在将绑定信息存储至用户数据库之后，可以获取订阅请求对应的目标信息。目标信息可以为绑定的应用功能节点与目标应用的报告事件对应的绑定信息，可以为与订阅请求对应的目标应用的报告事件，即使用目标应用时需要向网络汇报的信息。目标应用的类型不同，目标信息也可以不同，具体根据实际需求来确定。在一些实施例中，目标信息可以包括使用情况、状态报告等等。例如，目标信息可以为与应用功能节点绑定的目标应用的使用时长累计信息、开始/结束状态、流量使用情况等等。
本公开实施例中，在获取订阅请求对应的目标信息时，基于网络的具体结构，可以通过网络中的信息提供网元来从用户数据库获取到绑定的请求方应用功能节点AF1与目标应用的报告事件的订阅信息。信息提供网元可以将获取的目标信息直接发送至应用功能节点，也可以发送至网络开放功能节点，以使得网络开放功能节点获取到目标信息并发送应用功能节点。此处以通过网络开放功能节点为例进行说明。
信息提供网元用于从用户数据库获取需要的目标信息。信息提供网元可以根据会话状态而确定，会话状态不同则对应的信息提供网元也不同。会话状态可以为与目标应用之间的会话，具体可以包括会话建立状态或策略状态。其中，会话建立状态可以为建立或修改会话，策略状态可以为建立或修改策略关联。会话指的是目标用户在目标应用中的会话。策略关联指的是用户与网络建立会话所使用的会话策略，可以包括带宽、网速、接入策略、应用范围等等。例如，策略关联可以为哪些地方不能使用这些策略，哪些地方能够使用策略等等。
基于此，可以根据会话状态对应的信息提供网元，从用户数据库中获取所述目标用户的签约信息，并根据所述签约信息获取所述目标信息。通过获取签约信息，在建立连接时能够确定在哪个节点获取到哪些信息从而修改哪些策略，进一步根据签约信息获取目标信息，能够确定在使用目标应用时需要向网络汇报的信息，即用户数据库中与订阅请求匹配的绑定的应用功能节点与目标应用的报告事件。
图4中示意性示出了获取目标信息的流程图，参考图4中所示，主要包括以下步骤：
在步骤S410中，若所述会话状态为目标用户建立或修改会话，根据会话管理功能节点从所述用户数据库获取所述签约信息，并根据所述签约信息获取所述目标信息。
本公开实施例中，如果会话状态为目标用户建立或修改会话，其对应的信息提供网元为会话管理功能节点。会话管理功能节点SMF(Session Management Function)能够实现以下功能：会话建立、修改和释放、UE IP地址分配、确定会话的SSC模式等等。会话管理功能节点从用户数据库中获取到目标用户的签约信息，能够确定在哪个节点获取到哪些 信息，进一步根据签约信息来获取目标应用的目标信息，即获取到绑定的请求方应用功能节点与目标应用的报告事件所形成的绑定信息，以获取在使用目标应用的过程中需要汇报的信息。
在步骤S420中，若所述会话状态为目标用户建立或修改策略关联，根据策略与计费控制节点从所述用户数据库获取所述签约信息，并根据所述签约信息获取所述目标信息。
本公开实施例中，如果会话状态为目标用户建立或修改策略关联，其对应的信息提供网元为策略与计费控制节点。策略与计费控制节点PCF(Policy Control Function)包括以下功能：访问统一数据存储库中与策略决策相关的目标信息，提供策略规则等等。策略与计费控制节点从用户数据库中获取到目标用户的签约信息，能够确定在哪个节点获取到哪些信息，也可以得知存在应用功能节点针对目标应用订阅的相关报告。进一步根据签约信息来获取目标应用的目标信息，即获取到绑定的请求方应用功能节点与目标应用的报告事件的目标信息，以获取在使用目标应用的过程中需要汇报的信息。
图5中示意性示出了通过不同路径获取目标信息的过程，参考图5中所示，会话状态500为状态1建立或修改会话时，通过会话管理功能节点501从用户数据库502中获取目标应用的目标信息503，即通过路径1获取；会话状态500为状态2目标用户建立或修改策略关联时，通过策略与计费控制节点504从用户数据库502中获取目标应用的目标信息503。通过不同的会话状态，可经过不同的信息提供网元以及不同的路径来从用户数据库中获取目标信息，能够提高获取目标信息的准确性和及时性。
接下来，继续参考图2中所示，在步骤S220中，若确定所述目标应用满足触发条件，所述应用功能节点通过网络中的信息提供网元接收所述目标信息。
本公开实施例中，触发条件用于触发对目标信息进行报告。触发条件可以为所述目标用户与目标应用之间建立会话，且目标应用满足报告条件。目标用户与目标应用之间建立会话可以为目标用户与目标应用相关的会话建立资源和生成流量，即目标用户开始使用目标应用提供的业务。在目标用户使用目标应用的基础上，可以进一步判断目标应用是否满足报告条件。报告条件可以根据报告阀值等来确定，也可以根据订阅请求中包含的信息来确定。
图6中示意性示出了接收目标信息的流程图，参考图6中所示，主要包括以下步骤：
在步骤S610中，判断目标应用是否满足触发条件；若是，则转至步骤S620；若否，则转至步骤S630；
在步骤S620中，所述应用功能节点接收通过信息提供网元提供的所述目标信息；
在步骤S630中，所述应用功能节点无法接收目标信息。
本公开实施例中，如果目标用户使用目标应用，且目标应用满足报告条件，则可以触发应用功能节点接收通过网络中的信息提供网元提供的目标信息。具体地，如果应用功能节点的类型为第一类型网元，其发送订阅请求的过程经过了网络开放功能节点，则获取目标信息的过程可以包括：信息提供网元从用户数据库中获取目标信息，并发送至网络开放功能节点，网络开放功能节点再将目标信息发送至应用功能节点，以使应用功能节点接收，实现应用功能节点经过网络获取目标信息的功能。即，通过网络向应用功能节点提供所请求的目标用户或目标用户组的用户与目标应用的订阅事件或者信息。如果应用功能节点的类型为第二类型网元，其发送订阅请求的过程未经过网络开放功能节点，则获取目标信息的过程可以包括：信息提供网元从用户数据库中获取目标信息，并发送至应用功能节点，以使应用功能节点接收，实现应用功能节点经过网络获取目标信息的功能。
在一些实施例中，若应用功能节点为第一类型网元。如果会话状态为目标用户建立或修改会话，其对应的信息提供网元为会话管理功能节点。会话管理功能节点从用户数据库中获取目标信息，并发送至网络开放功能节点，网络开放功能节点再将目标信息发送至应用功能节点，实现应用功能节点经过所述网络开放功能节点接收会话管理功能节点获取的 目标信息的功能。如果会话状态为目标用户建立或修改策略关联，其对应的信息提供网元为策略与计费控制节点。策略与计费控制节点从用户数据库中获取目标信息，并发送至网络开放功能节点，网络开放功能节点再将目标信息发送至应用功能节点，实现应用功能节点经过所述网络开放功能节点接收策略与计费控制节点获取的目标信息的功能。
若应用功能节点为第二类型网元进行说明。如果会话状态为目标用户建立或修改会话，其对应的信息提供网元为会话管理功能节点。会话管理功能节点从用户数据库中获取目标信息，并发送至应用功能节点。如果会话状态为目标用户建立或修改策略关联，其对应的信息提供网元为策略与计费控制节点。策略与计费控制节点从用户数据库中获取目标信息，并发送至应用功能节点，实现应用功能节点接收策略与计费控制节点获取的目标信息的功能。
如果目标用户使用了目标应用，且目标应用不满足报告条件，或者是目标用户未使用目标应用，均可以认为目标应用不满足触发条件，此时应用功能节点无法经过网络接收目标信息。
本公开实施例中的技术方案，通过触发条件以及不同的路径来使得应用功能节点接收针对于不同应用功能节点提供的目标应用的目标信息，能够实现通过网络获取其他应用的相关信息的功能，增加了全面性和应用范围。
在步骤S230中，根据所述目标信息执行对应操作。
本公开实施例中，不同的目标信息关联的对应操作可以相同或不同，且对应操作可以根据业务需求而确定。对应操作可以为推送操作、调整操作、激活业务等等。
图7中示意性示出了第一类型网元对应的信息传输的交互流程图，参考图7中所示，主要包括应用功能节点AF1、网络开放功能节点NEF、用户数据库UDR、会话管理功能节点SMF、策略与计费控制节点PCF、目标应用的应用功能节点AF2，交互过程主要包括以下步骤：
步骤S701，应用功能节点AF1生成针对目标用户目标应用的订阅请求，并将订阅请求发送给关联的网络开放功能节点NEF。
其中，该订阅请求包括：用户(或用户组)ID、目标应用ID或目标服务提供商ID、目标报告信息或者事件以及其他可选条件。其他可选条件可以包括但不限于目标服务器地址、网络服务区域、订阅时长或有效性信息、报告阀值。
步骤S702，网络开放功能节点NEF将来自应用功能节点AF1的订阅请求发送到用户数据库UDR。
步骤S703，在用户数据库UDR中修改目标用户的签约信息中与目标应用对应的相关信息，并绑定请求方应用功能节点AF1与目标应用的报告事件，以进行存储。
步骤S704，当目标用户或目标用户组的用户建立或修改会话时，会话管理功能节点SMF从用户数据库UDR读取该目标用户的签约信息，并根据签约信息从用户数据库获取绑定的请求方应用功能节点AF1与目标应用的报告事件的目标信息。
步骤S705，当目标用户或目标用户组的用户建立或修改策略关联时，策略与计费控制节点PCF从用户数据库UDR读取该目标用户的签约信息，并根据签约信息从用户数据库获取绑定的请求方应用功能节点AF1与目标应用的报告事件的目标信息。
步骤S706，终端设备UE中的目标用户与应用功能节点AF2提供的目标应用建立会话。
步骤S707，会话管理功能节点SMF经过网络开放功能节点NEF向请求方应用功能节点AF1提供所请求的目标信息。
步骤S708，策略与计费控制节点PCF经过网络开放功能节点NEF向请求方应用功能节点AF1提供所请求的目标信息。
步骤S709，应用功能节点AF1根据接收到的目标信息进行对应操作。
本公开实施例中的技术方案，通过网络中的网络开放功能节点以及会话管理功能节点 或策略与计费控制节点向应用功能节点AF1提供基于订阅请求所请求的其他应用功能节点提供的目标应用的目标信息，能够增加全面性和准确性。
图8中示意性示出了第二类型网元对应的信息传输的交互流程图，参考图8中所示，主要包括应用功能节点AF1、用户数据库UDR、会话管理功能节点SMF、策略与计费控制节点PCF、目标应用的应用功能节点AF2，交互过程主要包括以下步骤：
步骤S801，应用功能节点AF1生成针对目标用户目标应用的订阅请求，并将订阅请求发送至用户数据库UDR。

步骤S803，当目标用户或目标用户组的用户建立或修改会话时，会话管理功能节点SMF从用户数据库UDR读取该目标用户的签约信息，并根据签约信息从用户数据库获取绑定的请求方应用功能节点AF1与目标应用的报告事件的目标信息。
步骤S804，当目标用户或目标用户组的用户建立或修改策略关联时，策略与计费控制节点PCF从用户数据库UDR读取该目标用户的签约信息，并根据签约信息从用户数据库获取绑定的请求方应用功能节点AF1与目标应用的报告事件的目标信息。
步骤S805，终端设备UE中的目标用户与应用功能节点AF2提供的目标应用建立会话。
步骤S806，会话管理功能节点SMF向请求方应用功能节点AF1提供所请求的目标信息。
步骤S807，策略与计费控制节点PCF向请求方应用功能节点AF1提供所请求的目标信息。
步骤S808，应用功能节点AF1根据接收到的目标信息进行对应操作。
本公开实施例中的技术方案，通过网络中的会话管理功能节点或策略与计费控制节点向应用功能节点AF1提供基于订阅请求所请求的其他应用功能节点提供的目标应用的目标信息，能够增加全面性和准确性。
图9中示意性示出了第一类型网元进行信息传输的传输路径图，参考图9中所示，主要包括应用功能节点AF1、网络开放功能节点NEF、用户数据库UDR、会话管理功能节点SMF、策略与计费控制节点PCF、目标应用的应用功能节点AF2，交互过程主要包括以下步骤：
在应用功能节点为第一类型网元时，应用功能节点AF1生成针对目标用户目标应用的订阅请求，并将订阅请求发送给关联的网络开放功能节点NEF。
网络开放功能节点NEF将订阅请求发送到用户数据库UDR，以绑定用功能节点AF1与目标应用的报告事件。
当目标用户或目标用户组的用户建立或修改会话时，会话管理功能节点SMF从用户数据库UDR获取目标信息，即路径1。当目标用户或目标用户组的用户建立或修改策略关联时，策略与计费控制节点PCF从用户数据库UDR获取目标信息，即路径2。
终端设备中的目标用户与应用功能节点AF2提供的目标应用的建立会话。
会话管理功能节点SMF将目标信息传输至网络开放功能节点NEF，以使网络开放功能节点NEF将目标信息发送至应用功能节点AF1，即路径1。策略与计费控制节点PCF将目标信息传输至网络开放功能节点NEF，以使网络开放功能节点NEF将目标信息发送至应用功能节点AF1，即路径2。
图10中示意性示出了第二类型网元进行信息传输的传输路径图，参考图10中所示，主要包括应用功能节点AF1、用户数据库UDR、会话管理功能节点SMF、策略与计费控制节点PCF、目标应用的应用功能节点AF2，交互过程主要包括以下步骤：
在应用功能节点为第二类型网元时，应用功能节点AF1生成针对目标用户目标应用的订阅请求，并将订阅请求发送给用户数据库UDR，以绑定用功能节点AF1与目标应用的 报告事件。
当目标用户或目标用户组的用户建立或修改会话时，会话管理功能节点SMF从用户数据库UDR获取目标信息，即路径1。当目标用户或目标用户组的用户建立或修改策略关联时，策略与计费控制节点PCF从用户数据库UDR获取目标信息，即路径2。

会话管理功能节点SMF将目标信息发送至应用功能节点AF1，即路径1。策略与计费控制节点PCF将目标信息传输至应用功能节点AF1，即路径2。
基于上述交互流程，即应用功能节点可以向网络订阅其他AF所支持的第三方应用的目标信息，例如相关流量的信息。进一步地，可以根据该目标信息，通过运营商的短信系统向该用户推送相关的增值短信。
若运营商想开发相关的短信增值服务，当监测到用户在使用某个第三方应用，即目标应用1时，运营商自身部署的网元，例如运营商IMS系统中的短信系统AF1，可以订阅应用功能节点AF2提供的目标应用1的使用情况作为目标信息，如该目标应用的使用时长累计信息。根据该目标信息，短信系统AF1可以向用户推送相应的套餐信息，实现业务增值。
在一些实施例中，某些应用会利用闲时进行业务升级服务。例如可以使用背景流量的功能，预先与网络协商好传输的时间和速率。但是有可能预设的时间内，用户突发使用其他高价值高带宽需求的业务。如果背景流量应用对应的应用功能节点AF1可以向网络订阅应用功能节点AF2提供的目标业务的开始/结束状态报告，就可以实时调整或暂停背景流量业务的传输，从而优化应用功能节点AF1侧和网络侧的资源利用率。
本公开实施例中的技术方案，一方面，可以基于非交互层，利用5G核心网网络的能力开放功能，在不需要目标应用参与的情况下即可向目标应用提供一定的开放信息，能够从网络中的信息提供网元获取用户对不同应用功能节点提供的目标应用的使用情况，避免了相关技术中只能通过应用层之间的相互交互来获取其他信息或者是应用功能节点无法通过网络获取用户使用其他应用的情况的局限性，填补了应用功能节点不能从5G网络获取用户使用其他应用的使用情况的空白，增加了应用范围和通用性，也提高了便捷性。另一方面，能够通过网络的信息提供网元向应用功能节点提供不同应用功能节点提供的目标应用的目标信息，实现应用功能节点向网络订阅其他应用功能节点的相关信息的功能，增加了全面性，且提高了操作效率。可以为网络针对AF开拓更多增值业务的机会。可以解决应用功能节点AF订阅与其不同的其他应用功能节点AF提供的应用的相关事件信息，且对于目标应用及其对应的应用功能节点AF没有任何影响。
