为便于理解本申请实施例的技术方案，以下对本申请实施例的相关技术进行说明，以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。
在一些场景下，一个终端可以单独处理一项任务，在另一些场景下，多个终端可以联合起来处理一项任务。
以下以联邦学习任务为例进行说明，对于联邦学习任务来说，多个终端联合起来处理一项学习任务。
在传统的机器学习建模中，通常是把模型训练需要的数据集合到一个数据中心然后再训练模型，之后通过训练好的模型进行预测。在横向联邦学习中，可以看作是基于样本的分布式模型训练，分发全部数据到不同的机器，每台机器从服务器下载模型，然后利用本地数据训练模型，之后返回给服务器需要更新的参数；服务器聚合各机器上的返回的参数，更新模型，再把最新的模型反馈到每台机器。在这个过程中，每台机器下都是相同且完整的模型，且机器之间不交流不依赖，在预测时每台机器也可以独立预测，可以把这个过程看作成基于样本的分布式模型训练。
图2是一种联邦学习的典型架构，其中服务器(Server)A是管理者，用于向各分布节点发送模型以及根据分布节点的反馈结果做模型更新，并将更新的模型再次发送给分布节点用于下一轮模型训练。图2中的B1、B2、…、Bk可以认为是多个不同的分布节点(即参与方)，每个分布节点有各自的本地数据，为了不将本地数据发送给其他人(如服务器A)，每个分布节点使用服务器A发送的模型在本地进行训练后将要更新的参数返回给服务器A。其中，分布节点(即参与方)可以是网络侧的网元也可以是终端。如图2所示，联邦学习的流程如下：
(1)参与方各自从服务器A下载最新模型，每个参与方利用本地数据训练模型，将得到的梯度向量加密后上传给服务器A。
(2)服务器A聚合各参与方的梯度向量，根据聚合后的梯度向量更新模型。
(3)服务器A返回更新后的模型给各参与方。
(4)各参与方更新各自的模型。
上述步骤(2)到步骤(4)进行多次迭代，实现对模型的多次更新，在一定条件下(如完成一定次数的迭代数量或模型的损失函数计算值低于预设值后)，完成模型训练。
在联邦学习任务中，较为重要的一件事情是对成员(即参与方)的选择，成员选择的好与坏对于联邦学习的性能(如收敛速度、模型训练结果)有着重要的影响。
需要说明的是，以上描述虽然是以联邦学习任务为例进行说明的，但是任何任务的处理，无论是单个终端处理的任务，还是多个终端联合处理的任务，为了提升任务处理效率，都有需求选择合适的终端来处理该任务。如何判断一个终端是否合适，或者说如何选择合适的终端，是需要解决的问题。为此，提出了本申请实施例的以下技术方案。
为便于理解本申请实施例的技术方案，以下通过具体实施例详述本申请的技术方案。以上相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。
需要说明的是，本申请实施例的技术方案可以应用于任何通信系统，包括但不限于5G系统 (5GS)、6G系统(6GS)等。
参照图3，第三方(也即本申请以下方案中的第二节点)可以是应用服务器或终端。对于常规业务来说(如图3中的左侧所示)，其效率与服务质量(Quality of Service，QoS)有关。对于人工智能或者机器学习业务来说(如图3中的右侧所示)，其效率不仅与QoS有关，还与信息质量(Quality of Information，QoI)有关，这里，通过5GS为第三方提供其分析出的QoI，可以帮助第三方为业务做出更好的决策，例如可以帮助第三方条件信息更好的终端来处理业务。需要说明的是，图3虽然以人工智能或者机器学习业务进行说明，但不局限于此，其他类型的业务也同样适用。
图4是本申请实施例提供的通信方法的流程示意图一，如图4所示，所述通信方法包括以下步骤：
步骤401：第一节点接收第二节点发送的第一请求消息，所述第一请求消息携带条件信息。
在一些可选实施方式中，所述第一节点为第一核心网网元。这里，相对于已有的核心网来说，所述第一核心网网元可以是一个新的功能网元，或者也可以是一个已有的功能网元。本申请对所述第一核心网网元的名称不做限定。
在一些可选实施方式中，所述第二节点为终端或应用服务器。
本申请实施例中，第二节点向第一节点发送第一请求消息，相应地，第一节点接收第二节点发送的第一请求消息，这里，所述第一请求消息用于请求获取推荐的候选终端。其中，所述第一请求消息携带条件信息。这里，所述条件信息用于选择候选终端。
本申请实施例中，所述条件信息用于确定一个或多个条件，例如：所述条件信息包括一个或多个条件的指示信息。
在一些可选实施方式中，所述条件信息用于确定以下至少一个条件：终端满足的区域条件、终端满足的数量条件、终端之间满足的距离间隔条件、终端满足的传输速率条件、终端满足的速度条件、终端在指定区域停留的时间条件、终端满足的运行轨迹条件、终端满足的服务质量(Quality of Service，QoS)条件、终端满足的业务能力条件。
上述方案中，可选地，传输速率条件、速度条件、时间条件、QoS条件的满足与否可以通过一个阈值来衡量。
例如，传输速率条件是否满足可以通过一个传输速率阈值来衡量，终端的传输速率大于等于该传输速率阈值则表示终端满足传输速率条件。
例如，速度条件是否满足可以通过一个速度阈值来衡量，终端的速度大于等于该速度阈值则表示终端满足速度条件。
例如，时间条件是否满足可以通过一个时间阈值来衡量，终端在指定区域停留的时间大于等于该时间阈值则表示终端满足时间条件。
例如，QoS条件是否满足可以通过一个QoS阈值来衡量，其中，对于一些QoS参数来说，终端的QoS值大于等于该QoS阈值则表示终端满足QoS条件；对于另一些QoS参数来说，终端的QoS值小于等于该QoS阈值则表示终端满足QoS条件。
进一步，在一些可选实施方式中，所述条件信息所确定的每个条件还携带一个附加条件，所述附加条件包括以下至少之一：满足条件的准确度、满足条件的有效时间。
这里，满足条件的准确度可以通过信任(confidence)值来表征，换句话说，通过confidence值可以表示满足条件的预测准确度。
这里，满足条件的有效时间可以是指满足条件的时间点或者也可以是指满足条件的时间段。
这里，需要说明的是，对于条件信息所确定的大部分条件来说，“是否满足条件或者条件的满足分值”通常是网络预测出的，由于“预测”有准确度、有效时间等问题，因而每个条件还关联“满足条件的准确度”和/或“满足条件的有效时间”这些附加条件。
需要说明的是，条件是否满足或者满足概率(对应于下述方案中的条件的满足分值)可以仅考虑条件本身，或者不仅考虑条件本身还需要考虑条件的附加条件。作为示例：条件1的附加条件为附加条件1，作为一种实现方式，条件1满足的情况下，认为条件1的满足分值为100％。作为另一种实现方式，条件1和附加条件1均满足的情况下，认为条件1的满足分值为100％。
步骤402：所述第一节点基于所述条件信息确定多个终端中的每个终端的条件满足情况，并基于所述多个终端中的每个终端的条件满足情况从所述多个终端中确定候选终端。
本申请实施例中，所述条件信息用于确定一个或多个条件，所述第一节点可以通过以下方式确定多个终端中的每个终端的条件满足情况：
方式一：对于所述多个终端中的每个终端，所述第一节点确定所述终端对应于所述一个或多个 条件中的每个条件的满足分值，基于所述终端对应于所述一个或多个条件中的每个条件的满足分值确定所述终端的条件满足值。这里，所述终端的条件满足值用于表征所述终端的条件满足情况。
在一些可选实施方式中，条件的满足分值为大于等于0且小于等于1的数，条件的满足分值用于表征条件的满足度。作为示例，条件的满足分值为1，代表100％满足条件。条件的满足分值为0，代表不满足条件。条件的满足分值为X％，代表X％的概率满足条件。
这里，条件的满足分值可以按需打分。作为示例，以QoS条件为例，终端的QoS值位于第一取值范围，那么可以将对应的满足分值打分为第一分值，终端的QoS值位于第二取值范围，那么可以将对应的满足分值打分为第二分值，终端的QoS值位于第三取值范围，那么可以将对应的满足分值打分为第三分值。可选地，第一取值范围的最高值小于第二取值范围的最低值，第二取值范围的最高值小于第三取值范围的最低值。举个例子：第一取值范围为低于QoS值1所界定的取值范围，第二取值范围为QoS值1至QoS值2所界定的取值范围，第三取值范围为QoS值2至QoS值3所界定的取值范围。作为示例，以附加条件中的“条件满足的准确度(即confidence)”为例，终端的条件满足的准确度位于第一准确度范围，那么可以将对应的满足分值打分为第一分值，终端的条件满足的准确度位于第二准确度范围，那么可以将对应的满足分值打分为第二分值，终端的条件满足的准确度位于第三准确度范围，那么可以将对应的满足分值打分为第三分值。
需要说明的是，上述条件的满足分值还可以按照其他方式进行打分，任何可以评估条件的满足程度的方式都可以用于来对条件的满足分值进行打分。
在一些可选实施方式中，所述一个或多个条件具有对应的权重值，所述第一节点基于所述一个或多个条件对应的权重值，对所述终端对应于所述一个或多个条件中的每个条件的满足分值进行加权求和，得到所述终端的条件满足值。这里，条件对应的权重值可以表征该条件的优先满足等级，条件对应的权重值越高，则代表该条件的优先满足等级越高。
作为示例：条件信息用于确定5个条件，分别为：条件1、条件2、条件3、条件4、和条件5。这5个条件对应的权重值分别为：w1、w2、w3、w4和w5，其中，5个权重值的总和等于1。终端的条件满足值可以通过以下公式确定：
w1*满足分值1+w2*满足分值2+w3*满足分值3+w4*满足分值4+w5*满足分值5。
其中，满足分值1是指条件1的满足分值，满足分值2是指条件2的满足分值，满足分值3是指条件3的满足分值，满足分值4是指条件4的满足分值，满足分值5是指条件5的满足分值。
需要说明的是，由于全部条件的权重值的总和等于1，而每个条件的满足分值为大于等于0且小于等于1的数，因此计算出的终端的条件满足值的大小在[0,1]范围内。
上述方案中，可选地，所述一个或多个条件对应的权重值携带在所述第一请求消息中；或者，所述一个或多个条件对应的权重值为预配置的。
在一些可选实施方式中，所述条件满足值为信息质量(Quality of Information，QoI)值，也即所述条件满足情况通过QoI值来表征。本申请对所述条件满足值的名称不做限定。
需要说明的是，由于第一节点是根据预测来选择候选终端的，选择的候选终端可能不会完全满足第二节点的要求，因此每个条件对应的权重值可以作为候选终端的选择依据，例如某一条件对应的权重值越高，则第一节点选择的候选终端满足该条件的可能性越高。
方式二：对于所述多个终端中的每个终端，所述第一节点确定所述终端是否满足所述一个或多个条件中的每个条件。
方式三：对于所述多个终端中的每个终端，所述第一节点确定所述终端是否满足所述一个或多个条件中的指定的条件。
这里，指定的条件的数目可以是一个或者多个。
本申请实施例中，所述第一节点接收第二节点发送的第一请求消息之后，可以与至少一个第三节点进行交互，从而从所述至少一个第三节点获取所述多个终端中的每个终端的分析信息。对于所述多个终端中的每个终端，所述第一节点基于所述终端的分析信息确定所述终端对应于所述一个或多个条件中的每个条件的满足分值或者确定所述终端是否满足所述一个或多个条件中的每个条件或者确定所述终端是否满足所述一个或多个条件中的指定的条件。
在一些可选实施方式中，所述分析信息包括以下至少之一：移动性信息、会话信息、网络性能信息。
在一些可选实施方式中，所述至少一个第三节点包括以下至少之一：数据分析网元、会话管理网元、移动性管理网元。作为示例，所述数据分析网元可以是网络数据分析功能网元(Network Data Analytics Function，NWDAF)。所述会话管理网元可以是会话管理功能网元(Session Management  Function，SMF)。所述移动性管理网元可以是接入和移动性管理功能网元(Access and Mobility Management Function，AMF)。
本申请实施例中，所述第一节点确定出多个终端中的每个终端的条件满足情况后，可以通过以下方式从所述多个终端中确定候选终端：
方式A：所述第一节点基于所述多个终端中的每个终端的条件满足值，确定条件满足值大于等于条件满足门限值的终端，将条件满足值大于等于条件满足门限值的终端确定为候选终端。
上述方案中，可选地，所述条件满足门限值携带在所述第一请求消息中；或者，所述条件满足门限值为预配置的。
作为示例：第一节点确定5个终端的条件满足值，其中，终端1的条件满足值为0.95，终端2的条件满足值为0.7，终端3的条件满足值为0.85，终端4的条件满足值为0.98，终端5的条件满足值为0.6。条件满足门限值为0.8，那么，第一节点可以确定出终端1、终端3和终端4的条件满足值均大于条件满足门限值，第一节点确定出候选终端包括终端1、终端3和终端4。
方式B：所述第一节点将满足所述条件信息所确定的全部条件的终端，确定为候选终端。
这里，所述第一节点在筛选候选终端时，将满足条件信息所确定的全部条件的终端确定为候选终端，将不满足条件信息所确定的任何一个或多个条件或不满足其中指定的一个或多个条件的终端，直接排除掉。
方式C：所述第一节点将满足所述条件信息所确定的指定的一个或多个条件的终端，确定为候选终端。
在一些可选实施方式中，所述第一节点确定一个或多个限定条件中的每个限定条件对应的候选终端。
作为示例：所述限定条件为时间段。所述第一节点确定一个或多个时间段中的每个时间段对应的候选终端。以所述第一节点确定3个时间段中的每个时间段对应的候选终端为例，3个时间段中的每个时间段对应的候选终端如下表1所示。
时间段 候选终端
时间段1 终端1、终端2、终端3、终端4、终端5
时间段2 终端1、终端3、终端5、终端7、终端9
时间段3 终端2、终端4、终端6、终端8、终端10
表1
从以上表1可以看出，不同的时间段对应的候选终端是不同的，这是由于不同的时间段内终端的条件满足值可能发生变化，导致终端的条件满足值发生变化的原因是终端对应于每个条件的满足分值发生了变化。
步骤403：所述第一节点向所述第二节点发送第一请求回复消息，所述第一请求回复消息携带所述候选终端的指示信息。
本申请实施例中，所述第一节点向所述第二节点发送第一请求回复消息，相应地，所述第二节点接收所述第一节点发送的第一请求回复消息，其中，所述第一请求回复消息携带所述候选终端的指示信息。
这里，需要说明的是，候选终端的数量可以一个或者多个。所述第一请求回复消息携带一个或多个候选终端的指示信息。
在一些可选实施方式中，所述第一请求回复消息携带一个或多个候选终端的标识信息，所述标识信息用于指示候选终端。作为示例：所述第一请求回复消息携带一个或多个候选终端的UE ID。
在一些可选实施方式中，所述第一请求回复消息还携带一个或多个候选终端的条件满足值。
作为示例：条件满足门限值为0.8，条件满足值大于等于0.8的终端为候选终端，以下表2列举出了每个候选终端的条件满足值。
候选终端 条件满足值
终端1 0.95
终端2 0.89
终端3 0.85
终端4 0.83
终端5 0.81
表2
在一些可选实施方式中，在上述步骤402中，所述第一节点确定一个或多个限定条件中的每个限定条件对应的候选终端，那么，所述第一节点向所述第二节点发送的第一请求回复消息携带所述一个或多个限定条件中的每个限定条件对应的候选终端的指示信息。作为示例，第一请求回复消息携带如表1所示的内容。
在一些可选实施方式中，所述第二节点接收到第一节点发送的第一请求回复消息后，可以从候选终端中选择一个或多个终端来处理任务。
进一步，可选地，如果所述第一请求回复消息中携带一个或多个限定条件中的每个限定条件(如时间段)对应的候选终端的指示信息，那么，第二节点可以从不同限定条件(如时间段)对应的候选终端中选择一个或多个终端来处理不同限定条件(如时间段)下的任务。作为示例，以表1为例，第二节点可以从时间段1对应的候选终端中选择终端1、终端2和终端3来处理在时间段1下的任务，第二节点可以从时间段2对应的候选终端中选择终端1、终端3和终端5来处理在时间段2下的任务，第二节点可以从时间段3对应的候选终端中选择终端2、终端4和终端6来处理在时间段3下的任务。这里，任务可以是但不局限于是联邦学习任务。
本申请实施例的技术方案，第一节点为第二节点进行服务，帮助第二节点得到合理的候选终端。由于第一节点仅将候选终端的指示信息提供给第二节点，因而不会暴露候选终端的隐私(如候选终端的分析信息)。此外，本申请实施例的技术方案充分使用现有架构和信令，对现有协议影响较小，易于实现。
图5是本申请实施例提供的通信方法的流程示意图二，如图5所示，所述通信方法包括以下步骤：
步骤501：第一节点接收第二节点发送的第一请求消息，所述第一请求消息携带终端的标识和条件信息。
在一些可选实施方式中，所述第一节点为第一核心网网元。这里，相对于已有的核心网来说，所述第一核心网网元可以是一个新的功能网元，或者也可以是一个已有的功能网元。本申请对所述第一核心网网元的名称不做限定。
在一些可选实施方式中，所述第二节点为终端或应用服务器。
本申请实施例中，第二节点向第一节点发送第一请求消息，相应地，第一节点接收第二节点发送的第一请求消息，这里，所述第一请求消息用于请求获取终端的条件满足值，进一步，可选地，所述第一请求消息用于请求获取终端的条件满足值是否大于等于条件满足门限值的判断结果。其中，所述第一请求消息携带终端的标识和条件信息。
这里，需要说明的是，终端的数量可以是一个或多个，对于多个终端的情况，多个终端可以对应相同的条件信息，或者，多个终端中的至少部分终端可以对应不同的条件信息。
在一些可选实施方式中，所述条件信息用于确定以下至少一个条件：终端满足的区域条件、终端满足的数量条件、终端之间满足的距离间隔条件、终端满足的传输速率条件、终端满足的速度条件、终端在指定区域停留的时间条件、终端满足的运行轨迹条件、终端满足的服务质量(Quality of Service，QoS)条件、终端满足的业务能力条件。
进一步，在一些可选实施方式中，所述条件信息所确定的每个条件还携带一个附加条件，所述附加条件包括以下至少之一：满足条件的准确度、满足条件的有效时间。
这里，满足条件的准确度可以通过信任(confidence)值来表征，换句话说，通过confidence值可以表示满足条件的预测准确度。
这里，满足条件的有效时间可以是指满足条件的时间点或者也可以是指满足条件的时间段。
需要说明的是，条件是否满足或者满足概率(对应于下述方案中的条件的满足分值)可以仅考虑条件本身，或者不仅考虑条件本身还需要考虑条件的附加条件。作为示例：条件1的附加条件为附加条件1，作为一种实现方式，条件1满足的情况下，认为条件1的满足分值为100％。作为另一种实现方式，条件1和附加条件1均满足的情况下，认为条件1的满足分值为100％。
步骤502：所述第一节点基于所述条件信息确定所述终端的条件满足值。
本申请实施例中，所述条件信息用于确定一个或多个条件，所述第一节点通过以下方式确定所述终端的条件满足值：
所述第一节点确定所述终端对应于所述一个或多个条件中的每个条件的满足分值，基于所述终端对应于所述一个或多个条件中的每个条件的满足分值确定所述终端的条件满足值。
在一些可选实施方式中，条件的满足分值为大于等于0且小于等于1的数，条件的满足分值用于表征条件的满足度。作为示例，条件的满足分值为1，代表100％满足条件。条件的满足分值为0，代表不满足条件。条件的满足分值为X％，代表X％的概率满足条件。
在一些可选实施方式中，所述条件满足值为信息质量(Quality of Information，QoI)值。本申请对所述条件满足值的名称不做限定。
在一些可选实施方式中，所述一个或多个条件具有对应的权重值，所述第一节点基于所述一个或多个条件对应的权重值，对所述终端对应于所述一个或多个条件中的每个条件的满足分值进行加权求和，得到所述终端的条件满足值。这里，条件对应的权重值可以表征该条件的优先满足等级，条件对应的权重值越高，则代表该条件的优先满足等级越高。
作为示例：条件信息用于确定5个条件，分别为：条件1、条件2、条件3、条件4、和条件5。这5个条件对应的权重值分别为：w1、w2、w3、w4和w5，其中，5个权重值的总和等于1。终端的条件满足值可以通过以下公式确定：
w1*满足分值1+w2*满足分值2+w3*满足分值3+w4*满足分值4+w5*满足分值5。
其中，满足分值1是指条件1的满足分值，满足分值2是指条件2的满足分值，满足分值3是指条件3的满足分值，满足分值4是指条件4的满足分值，满足分值5是指条件5的满足分值。
需要说明的是，由于全部条件的权重值的总和等于1，而每个条件的满足分值为大于等于0且小于等于1的数，因此计算出的终端的条件满足值的大小在[0,1]范围内。
上述方案中，可选地，所述一个或多个条件对应的权重值携带在所述第一请求消息中；或者，
所述一个或多个条件对应的权重值为预配置的。
需要说明的是，由于第一节点是根据预测来选择候选终端的，选择的候选终端可能不会完全满足第二节点的要求，因此每个条件对应的权重值可以作为候选终端的选择依据，例如某一条件对应的权重值越高，则第一节点选择的候选终端满足该条件的可能性越高。
本申请实施例中，所述第一节点接收第二节点发送的第一请求消息之后，可以与至少一个第三节点进行交互，从而从所述至少一个第三节点获取所述终端的分析信息。所述第一节点基于所述终端的分析信息确定所述终端对应于所述一个或多个条件中的每个条件的满足分值。
在一些可选实施方式中，所述分析信息包括以下至少之一：移动性信息、会话信息、网络性能信息。
在一些可选实施方式中，所述至少一个第三节点包括以下至少之一：数据分析网元、会话管理网元、移动性管理网元。作为示例，所述数据分析网元可以是NWDAF。所述会话管理网元可以是SMF。所述移动性管理网元可以是AMF。
进一步，在一些可选实施方式中，第一节点确定出终端的条件满足值后，确定所述终端的条件满足值是否大于等于条件满足门限值，具体地，第一节点可以将终端的条件满足值与条件满足门限值进行比较，判断终端的条件满足值是否大于等于条件满足门限值。
在一些可选实施方式中，所述条件满足门限值携带在所述第一请求消息中；或者，所述条件满足门限值为预配置的。
作为示例：第一节点确定终端的条件满足值为0.95，条件满足门限值为0.8，那么，第一节点可以确定出终端的条件满足值大于条件满足门限值。
步骤503：所述第一节点向所述第二节点发送第一请求回复消息，所述第一请求回复消息携带所述终端的条件满足值。
本申请实施例中，所述第一节点向所述第二节点发送第一请求回复消息，相应地，所述第二节点接收所述第一节点发送的第一请求回复消息，其中，所述第一请求回复消息携带所述终端的条件满足值。
在一些可选实施方式中，所述第一请求回复消息还携带第一指示信息，所述第一指示信息用于指示所述终端的条件满足值是否大于等于条件满足门限值。
这里，需要说明的是，终端的数量可以一个或者多个。所述第一请求回复消息携带一个或多个终端的条件满足值和/或第一指示信息。
本申请实施例的技术方案，第一节点为第二节点进行服务，帮助第二节点分析终端的条件满足值和/或终端的条件满足值是否大于等于条件满足门限值。由于第一节点仅将终端的条件满足值提供给第二节点，因而不会暴露候选终端的隐私(如候选终端的分析信息)。此外，本申请实施例的技术 方案充分使用现有架构和信令，对现有协议影响较小，易于实现。
图6是本申请实施例提供的通信方法的交互流程图，如图6所示，第三方(终端或应用服务器)向新的网络功能网元(NF)(即第一节点)发送第一请求消息，该第一请求消息携带条件信息、QoI门限值和权重值，其中，QoI门限值和权重值为可选携带，例如第一请求消息携带条件信息，QoI门限值和权重值是预配置的。NF可以将条件转换为5GS中已经定义的事件(如分析、事件触发、监测等事件)发送给NWDAF或者其他NF(如SMF、AMF等)，从NWDAF或者其他NF获得事件的结果(Result)。其中，对于一些条件来说，NF可以直接将其映射到5GS中已经定义的事件(例如，移动性预测、QoS预测等事件)，而对于另一些条件来说，NF可能需要结合条件推导出对应的事件。新的NF获得事件的结果后，根据该结果确定终端对应于每个条件的QoI分值，再结合每个条件的权重值推导出终端的QoI值，通过将终端的QoI值与QoI门限值进行比较，从而为第三方(终端或应用服务器)推荐出有效终端(也即候选终端)。需要说明的是，图6所述新的NF的名称不做限定，作为示例，可以将该新的NF称为按需QoI NF(On-demand QoI NF)。
在图6所示的交互流程中，第三方(终端或应用服务器)向新的NF)提供的条件信息可以包括以下至少一个条件：终端满足的区域条件、终端满足的数量条件、终端之间满足的距离间隔条件、终端满足的传输速率条件、终端满足的速度条件、终端在指定区域停留的时间条件、终端满足的运行轨迹条件、终端满足的QoS条件、终端满足的业务能力条件。进一步，上述方案中，速率条件、时间条件、QoS条件的满足与否可以通过一个阈值来衡量。例如，速率条件是否满足可以通过一个速率阈值来衡量，终端的速率大于等于该速率阈值则表示终端满足速率条件。例如，时间条件是否满足可以通过一个时间阈值来衡量，终端在指定区域停留的时间大于等于该时间阈值则表示终端满足时间条件。例如，QoS条件是否满足可以通过一个QoS阈值来衡量，其中，对于一些QoS参数来说，终端的QoS值大于等于该QoS阈值则表示终端满足QoS条件；对于另一些QoS参数来说，终端的QoS值小于等于该QoS阈值则表示终端满足QoS条件。
以下结合具体应用实例对本申请实施例的技术方案进行举例说明，需要说明的是，以下应用实例中，以条件满足值为QoI值为例进行说明的。
应用实例一
图7是本申请实施例提供的通信方法的流程示意图三，如图7所示，所述通信方法包括以下步骤：
步骤701a/b：应用服务器/终端向核心网发送第一请求消息，其中，所述第一请求消息携带条件信息。
这里，所述第一请求消息用于请求获取推荐的候选终端。
这里，所述第一请求消息携带条件信息，其中，条件信息所确定的条件包括但不限于以下至少之一：终端满足的区域条件、终端满足的数量条件、终端之间满足的距离间隔条件、终端满足的传输速率条件、终端满足的速度条件、终端在指定区域停留的时间条件、终端满足的运行轨迹条件、终端满足的QoS条件、终端满足的业务能力条件。
进一步，在一些可选实施方式中，所述条件信息所确定的每个条件还携带一个附加条件，所述附加条件包括以下至少之一：满足条件的准确度、满足条件的有效时间。
这里，满足条件的准确度可以通过信任(confidence)值来表征，换句话说，通过confidence值可以表示满足条件的预测准确度。
这里，满足条件的有效时间可以是指满足条件的时间点或者也可以是指满足条件的时间段。
步骤702：核心网进行内部交互，根据条件信息确定候选终端。
这里，直接与应用服务器/终端交互的网元可以称为第一核心网网元，相对于已有的核心网来说，所述第一核心网网元可以是一个新的功能网元，或者也可以是一个已有的功能网元。本申请对所述第一核心网网元的名称不做限定。第一核心网网元可以与其他核心网网元进行内部交互，从而从其他核心网网元获取终端的分析信息。在一些可选实施方式中，所述分析信息包括以下至少之一：移动性信息、会话信息、网络性能信息。在一些可选实施方式中，所述其他核心网网元包括以下至少之一：数据分析网元、会话管理网元、移动性管理网元。作为示例，所述数据分析网元可以是NWDAF。所述会话管理网元可以是SMF。所述移动性管理网元可以是AMF。
第一核心网网元基于终端的分析信息确定终端对应于条件信息所确定的每个条件的满足分值。在一些可选实施方式中，所述条件信息所确定的每个条件具有对应的权重值，第一核心网网元基于每个条件对应的权重值，对终端对应于每个条件的满足分值进行加权求和，得到终端的QoI值。这里，条件对应的权重值可以表征该条件的优先满足等级，条件对应的权重值越高，则代表该条件的 优先满足等级越高。
作为示例：条件信息用于确定5个条件，分别为：条件1、条件2、条件3、条件4、和条件5。这5个条件对应的权重值分别为：w1、w2、w3、w4和w5，其中，5个权重值的总和等于1。终端的QoI值可以通过以下公式确定：
w1*满足分值1+w2*满足分值2+w3*满足分值3+w4*满足分值4+w5*满足分值5。
其中，满足分值1是指条件1的满足分值，满足分值2是指条件2的满足分值，满足分值3是指条件3的满足分值，满足分值4是指条件4的满足分值，满足分值5是指条件5的满足分值。
进一步，第一核心网网元基于每个终端的QoI值，确定QoI值大于等于QoI门限值的终端，将QoI值大于等于QoI门限值的终端确定为候选终端。
作为示例：第一核心网网元确定5个终端的QoI值，其中，终端1的QoI值为0.95，终端2的QoI值为0.7，终端3的QoI值为0.85，终端4的QoI值为0.98，终端5的QoI值为0.6。QoI门限值为0.8，那么，第一核心网网元可以确定出终端1、终端3和终端4的QoI值均大于QoI门限值，第一核心网网元确定出候选终端包括终端1、终端3和终端4。
在一些可选实施方式中，第一核心网网元确定一个或多个限定条件中的每个限定条件对应的候选终端。作为示例：所述限定条件为时间段。所述第一节点确定一个或多个时间段中的每个时间段对应的候选终端。以所述第一节点确定3个时间段中的每个时间段对应的候选终端为例，3个时间段中的每个时间段对应的候选终端如上表1所示。
从以上表1可以看出，不同的时间段对应的候选终端是不同的，这是由于不同的时间段内终端的QoI值可能发生变化，导致终端的QoI值发生变化的原因是终端对应于每个条件的满足分值发生了变化。
步骤703a/b：核心网向应用服务器/终端发送第一请求回复消息，所述第一请求回复消息携带候选终端的指示信息。
这里，需要说明的是，候选终端的数量可以一个或者多个。所述第一请求回复消息携带一个或多个候选终端的指示信息。

在一些可选实施方式中，所述第二节点接收到第一节点发送的第一请求回复消息后，可以从候选终端中选择一个或多个终端来处理任务。
进一步，可选地，如果所述第一请求回复消息中携带一个或多个限定条件中的每个限定条件(如时间段)对应的候选终端的指示信息，那么，第二节点可以从不同限定条件(如时间段)对应的候选终端中选择一个或多个终端来处理不同限定条件(如时间段)下的任务。作为示例，以表1为例，第二节点可以从时间段1对应的候选终端中选择终端1、终端2和终端3来处理在时间段1下的任务，第二节点可以从时间段2对应的候选终端中选择终端1、终端3和终端5来处理在时间段2下的任务，第二节点可以从时间段3对应的候选终端中选择终端2、终端4和终端6来处理在时间段3下的任务。这里，任务可以是但不局限于是联邦学习任务。
