在本申请中，TA功能实体负责任务的生命周期管理，如基于任务的QoS参数完成任务部署、启动、删除、修改、监控等，包括调控算力、算法、数据、连接四要素来进行任务的QoS保障。其中，算力包括算力资源；算法为实现AI模型训练的算法；数据为执行任务所需的数据，如任务的输入数据；连接即设备之间的连接关系。任务的QoS参数可以包括以下至少一项：收敛时间、精度、能耗、任务所需的资源。收敛时间例如可以为人工智能(artificial intelligence，AI)模型的收敛时间。精度例如可以为AI模型的精度，任务所需的资源例如可以包括以下至少一项：算力资源、时频资源。算力资源例如可以包括以下至少一项：任务所需的内存、任务所需的中央处理器(central processing unit，CPU)数目、图形处理器数目(Graphics Processing Unit)。时频资源，即时域资源和频域资源。时域资源例如可以为资源块(resource block，RB)、资源单元组(resource-element group，REG)等，频域资源例如可以为分量载波(component carrier，CC)、带宽部分(bandwidth part，BWP)等。任务的QoS参数所包含的算力资源例如可以为任务所需的平均算力资源。
进一步的，TA功能实体可以接收来自网络内部的任务和QoS参数，也可以通过网络能力开放(network capability exposure，NCE)技术接收来自第三方实体的服务请求，服务请求包括第三实体请求的服务需求，服务需求可以包括工作流和QoS参数，工作流包括至少一个任务的任务流，其内部的一个任务的执行结果可以为另一任务的输入。如，工作流包括任务1、任务2、任务3，当任务1执行完成后，需要将任务1的执行结果作为任务2的输入，在任务2执行完成后，需要将任务2的执行结果作为任务3的输入。其中，第三方实体例如可以为互联网服务提供商(internet service provider，ISP)和互联网内容提供商(internet content provider，ICP)。可以理解，TA功能实体具备服务编排管控功能，即TA功能实体可以将来自网络内部 的任务或工作流中的任务创建任务实例，分配任务的标识信息以及设置任务的QoS参数。
进一步的，TA功能实体可以将任务实例部署到具体的节点上去执行，包括根据任务的QoS参数以及各节点的算力情况进行合理分配，在节点上创建TE功能实体，以及下发任务的配置信息。在任务部署成功后，启动任务并实时监控、调整任务的执行过程，直到任务结束后，删除任务的上下文信息。
在一种可能的实施方式中，任务的配置信息包括用于执行任务的配置信息和用于建立任务的上下文信息的配置信息。任务的上下文信息包括以下至少一项：用于建立任务的上下文信息的配置信息、任务的标识信息、第二节点中TE功能实体的标识信息、TE功能实体的地址信息。

在本申请中，TS功能实体可以建立并维护任务的上下文信息，从而对任务进行控制。其中，TS功能实体主要有三大核心特性。
其一，TS功能实体负责任务执行的实时控制，实现通信和计算深度融合。网络环境是动态变化的，如通信连接会发生切换、拉远拉近等各种情况，TS能够感知网络环境变化，进而可以实时调整算力、算法等配置，对算力、连接、数据、算法进行协同优化，保障任务的顺利执行和QoS要求。其中，网络环境变化包括：第二节点进入空闲态；或，第二节点进行小区切换；或，第二节点中执行的任务中断。
其二，TS功能实体负责任务调度，包括单任务和多任务调度。其中，单任务调度指的是，任务是一个过程，期间对于时频资源和算力资源的需求是不断变化的，需要实时调度；多任务调度指的是，TS功能实体可以部署在接入网设备或者核心网设备，其下分布着多种算力资源，可以部署不止一个任务，这些任务在时频资源和算力资源时需要TS功能实体根据任务的QoS参数进行调度。
其三，TS功能实体需要接受TA功能实体管理控制。TS功能实体不能作为任务管控架构外的功能独立存在，其必须接受TA功能实体的管理控制。
在本申请中，TE功能实体负责任务的执行，并进行业务逻辑上的数据交互。TE功能实体由TA功能实体创建。TA功能实体可以根据各网元的算力情况来决定任务的分配，一旦确定执行网元，下发指令在该网元上为任务创建TE功能实体。
工作流包括多个任务的任务流，多个任务可以部署在多个TE功能实体执行，因此TE功能实体间存在数据的交互。TE功能实体间的交互属于任务执行面，是业务逻辑，不需要TA功能实体、TS功能实体干预。即，某个TE功能实体1的数据要传递给另一个TE功能实体2时，可以自行发起，不需要TA功能实体、TS功能实体从任务控制面下发指令来触发。
在一种可能的实施方式中，TA功能实体、TS功能实体和TE功能实体可以为独立的设备， TA功能实体可以接入和移动性管理功能(access and mobility management function，AMF)网元通信，其中，AMF网元主要负责移动性管理、接入管理等服务。在又一种可能的实施方式中，TA功能实体、TS功能实体和TE功能实体也可以分别部署在相应的节点中，即TA功能实体可以部署在第三节点中，如SMF；TS功能实体可以部署在第一节点中；TE功能实体可以部署在第二节点中，在此不做限定。应理解的，第一节点为核心网设备，部署在第一节点的TS功能实体可以管理核心网设备的算力资源和MEC实体的算力资源；第一节点为接入网设备，部署在第一节点的TS功能实体可以管理第一节点的算力资源和第二节点的算力资源。当接入网设备为CU、DU分离的设备，TS功能实体的控制功能可以部署在CU上，TS功能实体的调度功能可以部署在DU上，即TS-control可以部署在CU上，TS-schedule可以部署在DU上。在另一可能的实施方式中，TS功能实体和TE功能实体可以部署在同一节点中，如TS功能实体和TE功能实体可以部署在第一节点中。

示例性的，第一终端设备的网络环境变化为第一终端设备进入空闲态，第一终端设备进入空闲态的概率为1，即表示第一终端设备进入空闲态已发生；第一终端设备进入空闲态的概率为0.8，即表示第一接入网设备预测第一终端设备的网络环境变化。
在一可能实施方式中，第一任务例如可以为AI训练任务、AI推理任务或AI感知任务。在另一可能的实施方式中，第一任务例如可以为前述这些任务的子任务，在此不做限定。其中，第一任务的数量可以为一个或多个，在此不做限定。另外，在一可能的实施方式中，一个任务可以对应一个TE功能实体，但一个TE功能实体可以用于执行一个或多个任务。即，一个TE功能实体在一个任务执行完成后，还可以执行另一个任务。

可选的，在步骤401之前，本方案还可以包括：第一接入网设备确定发生第一终端设备的网络环境变化的概率大于或等于预设阈值。其中，预设阈值可以是协议预先定义的，或固定值，在此不做限定。即可以看出，第一接入网设备可以通过确定发生第一终端设备的网络环境变化的概率大于或等于预设阈值后，生成并发送第一消息，使得核心网设备可以根据第一消息提前更新第一任务的配置信息，进而可以提前管理第一任务。另外，也在网络环境实际发生变化时减少了更新第一任务的配置信息所消耗的时间。
402、核心网设备从第一接入网设备接收第一消息。
相应的，第一接入网设备向核心网设备发送第一消息。
