Description

Method and device for establishing task tunnel Technical Field The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for establishing a task tunnel. Background In future sixth generation (6 th generation, 6G) communication systems, networks need to efficiently co-schedule heterogeneous resources, such as computing power, data or models, in order to support new services. In a 6G communication system, a process of cooperatively completing a specific object through multidimensional resources (such as computational power, data, models, etc.) is called a "task". In order to allow tasks to be controllably executed in the network, new logic functions, such as Task Anchors (TAs) and Task Executors (TEs), are required. The TA is responsible for lifecycle management of tasks including task deployment, start, delete, modify, monitor, etc. The TE is responsible for specific execution of tasks and for data interaction on the task logic. The TA may receive external task requests, and deploy the tasks to one or more TEs for execution. In a 6G communication system, a task control function (task control function, TCF) is added to a core network to provide TA functions, and a task processing function (task process function, TPF) is added to provide TE functions. In addition, the terminal may provide TE functionality. The TCF may deploy a task to be executed on at least one terminal and/or at least one TPF, where different task executives need to interact with task data during task execution. For a certain task, how to establish a tunnel for the task so as to realize interaction of task data is a technical problem to be solved. Disclosure of Invention The application provides a method and a device for establishing a task tunnel, wherein a tunnel for a first task is established between access network equipment and TFF, and task data of different task executors can be forwarded by using the tunnel in a routing way. In a first aspect, a method for establishing a task tunnel is provided, wherein an execution body of the method is a TFF or a module (such as a chip or a circuit) in the TFF, and the method comprises the steps of receiving a first request message from a Task Control Function (TCF), wherein the first request message is used for requesting the TFF to establish a tunnel of a first task, the first task is completed through multi-dimensional resource cooperation, sending a first response message responding to the first request message to the TCF, the first response message comprises tunnel information of the TFF related to the first task, and receiving tunnel information of access network equipment related to the first task from the TCF. Optionally, the tunnel of the first task includes a tunnel between the access network device associated with the first task and the TFF associated with the first task. By the above design, a tunnel for the first task can be established between the access network device and the TCF, and the at least one terminal and/or the at least one TPF participating in the first task can use the tunnel to transmit task data. Further, for uplink task data sent to the TPF by the terminal, the access network device only needs to forward to the TFF, and the access network device does not need to perceive which TPF to send to, so that complexity of the access network device is simplified. For downlink task data sent to the access network device by the TPF, the TPF only needs to forward to the TFF, and the position of the terminal is not required to be perceived, so that the complexity of the TPF is simplified. In one design, the first request message includes an identification of the first task and information of a task processing function TPF associated with the first task. Further, the first request message also comprises at least one of information of the terminal associated with the first task, a data packet detection rule associated with the first task, a data packet forwarding rule associated with the first task, or an identification of the TCF. Optionally, the first request message may further include a session identifier of the first task. Through the design, the tunnel of the first task can be established with the granularity of the task. Or tunnels of the first task may be established at granularity of the session. When the tunnel of the first task is established with the granularity of the session, the first request message may further include the session identifier of the first task in addition to the content. When tunnels for a first task are established at session granularity, more fine-grained tunnels may be established. In one implementation, the TFF may establish a tunnel context for the first task upon receipt of the first request message. And the TFF subsequently carries out routing forwarding on the task data of the first task according to the tunnel context of the first task. The content included in the tunnel contex
