Wherein, the L1 may include a Physical (PHY) layer, etc., and the L2 may include a service data adaptation (SERVICE DATA adaptation protocol, SDAP) layer, a packet data convergence layer protocol (PACKET DATA convergence protocol, PDCP) layer, a radio link control (radio link control, RLC) layer, a medium access control (MEDIA ACCESS control, MAC) layer, etc. The service NAS layer mainly implements NAS services, for example, basic NAS services (such as access management service, mobility management service) and new NAS services (such as computing service, awareness service, and artificial intelligence service) may be implemented.

The protocol layer between the terminal device and the RAN may be AN Access Network (AN) protocol layer, for example, including L1 and L2 related protocol layers, which is not limited in this aspect of the present application.

The protocol layer between the RAN and the signaling distribution network element may be a protocol layer (RAN-CN protocol layer) between the RAN and a Core Network (CN), which is not limited in this regard.

The protocol layer between the signaling distribution network element and the NAS service network element may be a service interface protocol, for example, including HTTP/2 or HTTP/3, secure transport layer (transport layer security, TLS), TCP/QUIC, IP, L2, L1, and other protocols.

The protocol stacks described above are examples only and should not be limiting, such as having fewer layers or more layers than examples in the protocol stack.

In combination with the foregoing description, in the present application, NAS functions may be served, and both the terminal device and the NAS service network element may register NAS services provided by themselves as needed, so as to implement flexible inter-call of NAS services as needed, which will be described in detail below.

In the application, the names of each message and each information are only examples, and the names of the messages or the information can be changed along with the evolution of the network architecture and the appearance of a new service scene, but the technical scheme provided by the embodiment of the application is also applicable to similar technical problems.

When the method provided by the application is applied to the system shown in fig. 1, the terminal device can be the terminal device or a chip or a module in the terminal device in fig. 1, the signaling distribution network element can be the chip or the module in the signaling distribution function network element in fig. 1, and the calculation management network element can be the chip or the module in the calculation management network element in fig. 1.

Fig. 3 is a schematic flow chart of a communication method according to an embodiment of the present application.

Step 301, a terminal device sends a first request message to a signaling distribution network element.

Correspondingly, the signaling distribution network element receives the first request message.

In the present application, the terminal device may send the first request message to the signaling distribution network element through the access network device, that is, after the access network device receives the first request message, the first request message is forwarded to the signaling distribution network element.

In the present application, the message name of the first request message is not limited, and for example, the first request message may also be referred to as a computing task resource request message or a computing task establishment request message.

The terminal device transmits the first request message in any case, and the present application is not limited thereto. For example, if the terminal device performs the first computing task and the terminal device determines to offload the first computing task to the network for execution according to the policy information, the first request message may be sent. The policy information may be preset or configured at the network side, for example, before step 301, the computing management network element may send the policy information to the terminal device through the signaling distribution network element. The policy information is used to instruct the terminal device to send the data corresponding to the computing task to the network for processing, and it can be understood that the policy information indicates a condition for offloading the data corresponding to the computing task to the network for execution. Conditions indicated by policy information include, for example, performing an offload process on computing tasks having computing resource requirements greater than or equal to a resource threshold and latency requirements less than or equal to a latency threshold. Policy information may also be referred to as a computational task offload policy, and the name of the policy information is not limited in this disclosure. The conditions for the indication of the policy information in the present application are not limited and will not be described in detail herein.

In the present application, the first computing task may be a task that an upper layer application of the terminal device (for example, an application program in the terminal device) requests to execute. In one implementation, the first computing task includes processing the first data. For example, the first data may be image data, the first computing task may include image rendering or image compression of the image data, or the first computing task may include AI image generation from the image data, the first data may be video data, the first computing task may include AI video generation from the video data, the first data may be voice data, and the first computing task may include audio compression of the audio data.

In the application, the first request message is used for requesting to call the computing service. The first request message may also be used to instruct the signaling distribution network element to send a second request message to the computing management network element, the second request message being used to request allocation of computing resources for the first computing task. In one implementation, the first request message includes identification information of the computing service, and the identification information of the computing service is used for sending the second request message to the computing management network element by the signaling distribution network element. Optionally, the first request message comprises a second request message.

Wherein the computing resources include hardware resources for processing computing tasks, e.g., the computing resources include at least one of central processor (central processing unit, CPU) resources, graphics processor (graphics processing unit, GPU) resources, and storage resources. The application is not limited in the implementation of the computing resources.

The first computing task may be a computing task corresponding to a computing service, and the computing service may correspond to a plurality of computing tasks.

Alternatively, in the present application, the first request message may also be used to request allocation of computing resources for the first computing task.

The first request message may also include identification information of the first session. The first session is a session established between the terminal device, the computing management network element and the computing processing node, and the first session is a session for carrying the computing task, which can be understood as a user plane channel established between the terminal device and the computing management network element, and the first session can support unloading of the computing task and issuing of a computing result of the computing task. For example, the first session may be a protocol data unit (protocol data unit, PDU) session, the first session may be a session similar to a PDU session, for example, the first session may be referred to as a computing session. One first session may correspond to one or more computing tasks, i.e., one first session may carry one or more computing tasks, multiple computing tasks may have the same business requirements and business attributes, such as multiple application-initiated image rendering computing tasks may be carried on the same session.

The first session may be initiated by the terminal device, and the specific procedure for establishing the first session is not limited by the present application, and may refer to the flow shown in fig. 4 below, for example. The establishment of the first session may be completed before step 301.

In the present application, the first request message may further include other information, for example, the first request message further includes at least one of identification information of the terminal device, task type information of the first computing task, and computing resource requirement information of the terminal device, where the computing resource requirement information is used to indicate a second computing resource, the second computing resource is a computing resource that the terminal device desires to acquire, and the computing resource requirement information may indicate information such as a resource number of the second computing resource. The task type information of the first computing task may indicate a task type of the first computing task, e.g., the task type of the first computing task is image rendering or image generation or video generation, etc. The task type information of the first computing task may further indicate computing resources required by the first computing task, the number of resources of computing resources required by computing tasks of different task types may be different, and an association relationship between the task type of the computing task and the number of resources of computing resources required by the computing task may be established in advance, so that the computing management network element may determine the number of resources of computing resources required by the computing task according to the task type of the computing task.

In one implementation, the first request message further includes a computing task establishment NAS container (container), where the computing task establishment NAS container includes at least one of identification information of the first session, type information of the first session, identification information of the terminal device, identification information of the first computing task, task type information of the first computing task, and computing resource requirement information, and the signaling distribution network element does not parse the computing task establishment NAS container, but forwards the computing task establishment NAS container to the computing management network element.

The type information of the first session is used for indicating the type of the first session, for example, the type of the first session can be a PDU session or an Ethernet PDU session based on IP, and the type of the first session can also be a session type such as an AI task session or an image task session.

Wherein in an IP-based PDU session, data is transmitted in the form of IP packets. In an ethernet PDU session, data is transmitted in the form of ethernet frames.

The AI task session refers to a session for carrying the calculation task related to the AI task, and the image task session refers to a session for carrying the calculation task related to the image task. Other types of first session are also possible in the present application, and are not particularly limited.

The identification information of the first computing task and the type information of the first computing task may be the same information, i.e., the identification information or the type information of the first computing task may indicate the first computing task and the type of the first computing task.

Step 302, the signaling distribution network element sends a second request message to the computation management network element, where the second request message is used to request to allocate computing resources for the first computing task.

Correspondingly, the computing management network element receives a second request message from the signaling distribution network element.

Optionally, before step 301, the computing management network element performs NAS service registration in the NAS service management network element. In the NAS service registration process, the computing management network element registers NAS services which can be provided by the computing management network element in the NAS service management network element as computing services.

The specific content of the NAS service registration procedure is not limited, and will not be described herein.

Optionally, before step 301, the signaling distribution network element may determine, by the NAS service management network element, that the NAS service provided by the computing management network element is a computing service. For example, the signaling distribution network element obtains information of the computing management network element through the NAS service management network element. The information of the computing management network element is used to instruct the computing management network element to provide computing service, and the information of the computing management network element may also be referred to as NAS service information of the computing management network element. For example, the information of the computing management network element includes the identification information of the computing management network element and the identification information of the computing service, such as an association relationship between the identification information of the computing management network element and the identification information of the computing service. The information of the computing management network element may also include address information of the computing management network element (e.g., the address information is a fully qualified domain name (fully qualified domain name, FQDN) or IP address). The identification information of the computing management network element is used for identifying the computing management network element and/or the type of the computing management network element, and can also be called as type information of the computing management network element, the identification information of the computing service can also be replaced by description such as service name information or index information of the computing service, and the identification information of the computing service is used for identifying the computing service.

The specific content of the process of obtaining the information of the computing management network element is not limited, and will not be described herein.

In the present application, the message name of the second request message is not limited, and for example, the second request message may also be referred to as a calculation task resource request message or a calculation task establishment request message.

The signaling distribution network element may determine, according to the first request message, that the terminal device requests to invoke the computing service, and may also determine to send a second request message to the computing management network element. How the signaling distribution network element determines the computational management network element, the application is not limited and several possible implementations are presented below.

In one implementation, the first request message includes identification information of the computing service, and the signaling distribution network element may determine the computing management network element according to the identification information of the computing service in the first request message.

For example, the signaling distribution network element may determine the computing management network element according to an association relationship between the identification information of the computing management network element and the identification information of the computing service. Before step 301, the signaling distribution network element may obtain information of the calculation management network element through the NAS service management network element, where the information of the calculation management network element may indicate the association relationship.

In this implementation manner, after the signaling distribution network element determines the computing management network element, the terminal device may further establish a first session, so that the terminal device transmits data corresponding to the first computing task to the network side through the first session. The specific flow of establishing the first session may be referred to the following description.

In another implementation, the first request message includes identification information of the computing service and identification information of the first session, and the signaling distribution network element may determine the computing management network element according to the identification information of the first session and the identification information of the computing service.

For example, the signaling distribution network element may determine the computing management network element according to an association relationship between the identification information of the first session, the identification information of the computing management network element, and the identification information of the computing service. The signaling distribution network element may determine the association relationship during the process of establishing the first session, and the specific process of establishing the first session may refer to the following description, which is not repeated herein. In this implementation, the process of establishing the first session may precede step 301.

In this implementation manner, the computing management network element determined by the signaling distribution network element is associated with the first session, that is, the first session for carrying the computing task has been established between the terminal device and the computing management network element, so that the terminal device may directly transmit, to the network side, data corresponding to the first computing task through the first session.

In the present application, the second request message may include at least one of identification information of the first session, type information of the first session, identification information of the terminal device, task type information of the first computing task, and computing resource demand information. For example, the first request message comprises a computing task establishment NAS container, and the signaling distribution network element may include the computing task establishment NAS container as part of the second request message, i.e. the second request message comprises the computing task establishment NAS container.

The second request message may further include other information, which is not limited in this aspect of the application and will not be described here.

Step 303, the computing management network element allocates a first computing resource for the first computing task according to the second request message.

In the present application, the computing resources may be provided by a computing processing node, and how the computing management network element determines the computing processing node for providing the first computing resource, which is not limited by the present application, and an example is given below.

Prior to step 303, a first session may be established between the terminal device and the computing management network element. In the first session establishment procedure, the computing management network element may determine at least one computing processing node, and how the computing management network element determines the at least one computing processing node may be referred to in the following description, which is not repeated herein.

The computing management network element may establish a management relationship of at least one computing processing node with the first session, the at least one computing processing node being operable to provide computing resources for computing tasks carried by the first session.

In one implementation, the second request message includes identification information of the first session. After the second request message is acquired by the computing management network element, at least one computing processing node associated with the first session may be determined from the identification information of the first session. The computing management network element may select one or more computing processing nodes from the at least one computing processing node, which may be part or all of the at least one computing processing node. The application is not limited in how the computing management network element specifically selects one or more computing processing nodes. For example, the computing management network element may select a computing processing node of the at least one computing processing node having a computing load less than or equal to a load threshold.

As another example, one computing processing node may support at least one computing task, such as one computing processing node supporting an AI model training task and another computing processing node supporting an image generation task. The computing management network element selects one or more computing processing nodes supporting the first computing task from the at least one computing processing node.

The computing management network element may allocate a first computing resource for the first computing task from the computing resources provided by the computing processing node. The number of the computing processing nodes providing the first computing resource for the first computing task is not limited, and one or more computing processing nodes may provide the first computing resource for the first computing task. The one or more computing processing nodes may be selected from at least one computing processing node associated with the first session.

In the present application, how the computing management network element determines the first computing resource is not limited by the present application.

In one implementation, the second request message includes at least one of type information of the first computing task or computing resource requirement information of the terminal device. The first computing resource may be determined based on at least one of task type information and computing resource demand information for the first computing task. For example, the task type information of the first computing task may indicate a task type of the first computing task, the number of resources of computing resources required by the computing tasks of different task types may be different, and the computing management network element may determine, according to the task type information, the number of resources of computing resources required by the terminal device to execute the computing task corresponding to the task type, so that the first computing resource of the corresponding number of resources may be allocated. For another example, the computing management network element may determine the second computing resource according to the computing resource requirement information, so that the first computing resource may be determined according to the second computing resource, e.g., the number of resources of the first resource allocated by the computing management network element is greater than or equal to the number of resources of the second resource.

The foregoing is merely an example, and the task type information and the second computing resources of the first computing task may not be considered when the computing management network element determines the first computing resource, but the first computing resource may be determined according to the number of resources actually provided by the computing processing node, or the first computing resource may be determined according to other parameters when the computing management network element determines the first computing resource, which is not limited in the present application.

Step 304, the computing management network element sends the information of the first computing resource to the signaling distribution network element.

Accordingly, the signaling distribution network element receives information of the first computing resource from the computing management network element.

For example, the computing management network element sends a second response message to the signaling distribution network element, the second response message including information of the first computing resource.

In the present application, the information of the first computing resource may indicate the number of resources of the first computing resource, and may also indicate a computing processing node to which the first computing resource belongs. The unit of the number of resources of the first computing resource may be floating point operations per second (floating point operations per second, FLOPS), and the application is not limited thereto. For example, the information for the first computing resource indicates that the number of resources for the first computing resource is 2000FLOPS.

Step 305, the signaling distribution network element sends information of the first computing resource to the terminal device.

Correspondingly, the terminal device receives the information of the first computing resource from the computing management network element through the signaling distribution network element.

For example, the signaling distribution network element sends a first response message to the terminal device, the first response message comprising information of the first computing resource.

In one implementation, the first response message may further include information such as identification information of the first session, identification information of the first computing task, and the like. For example, the first response message includes a NAS container including information such as identification information of the first session, identification information of the first computing task, and information of the first computing resource.

Optionally, if the terminal device determines that the number of resources of the first computing resource is less than the number of resources required to satisfy the processing of the first computing task, the terminal device may request the computing resource again, and the specific process is not described again.

And 306, the terminal device sends second data to the computing processing node according to the information of the first computing resource, wherein the second data is part or all of the first data.

In the present application, the terminal device may determine the data amount of the second data according to the first computing resource. Optionally, the second data is a maximum amount of data that can be processed by the first computing resource. For example, the terminal device determines the amount of data processed by the first computing resource, and the amount of data of the second data may be the amount of data processed by the first computing resource. For example, the terminal device determines that the first computing resource is capable of processing half of the first data, then the second data may be half of the first data.

The terminal device may send the second data to the computing processing node, from which the first computing task is performed. For example, the terminal device may send a calculation task offload request message to the calculation processing node through the first session, where the calculation task offload request message is used to request to execute the first calculation task according to the second data, the calculation task offload request message may include the second data, and the calculation task offload request message may further include information such as identification information of the first calculation task, identification information of the first session, and the like.

The terminal device may not directly send the calculation task unloading request message to the calculation processing node, and the calculation task unloading request message may be forwarded to the calculation processing node through devices such as an access network device, and the specific process is not limited by the present application and is not repeated herein.

Optionally, step 307, the computing processing node sends the processing result of the second data.

Accordingly, the terminal device receives the processing result of the second data from the calculation processing node.

The processing result of the second data is determined based on the second data.

For example, the second data is image data, the first computing task is image rendering, the processing result of the second data may be a rendered image, the second data is image data, the first computing task is video generation, the processing result of the second data may be video generated according to the image data, the second data is image data, the first computing task is image generation, the processing result of the second data may be an image generated according to the image data, the second data is AI model training data, the first computing task is AI model training, and the processing result of the second data may be a trained AI model. The above is merely an example, and other forms of processing the second data are possible, which is not limited by the present application.

In one implementation, the computing processing node may send a computing task offload response message that includes a processing result of the second data. The computing task offload response message may also include other information, as the application is not limited in this regard.

The terminal device may also determine a processing result of the first computing task based on the processing result of the second data. For example, the terminal device combines the processing result of the second data with the processing result of the third data locally performed by the terminal device, and obtains the processing result of the first computing task. The third data is data except the second data in all data processed by the first computing task.

Optionally, after the terminal device obtains the processing result, the first computing resource may also be released. For example, the terminal device sends a first resource release request message to the signaling distribution network element, where the first resource release request message is used to request release of the first computing resource. Correspondingly, the signaling distribution network element receives a first resource release request message from the terminal device, and sends a second resource release request message to the computing management network element according to the first resource release request message, wherein the second resource release request message is used for requesting to release the first computing resource. The first resource release request message and the second resource release request message may include information such as identification information of the first session, identification information of the first computing task, and information of the first computing resource, which is not limited in the present application. The computing management network element may instruct the computing processing node to release the first computing resource allocated for the first computing task, if the computing management network element receives the second resource release request message. The computing processing node may no longer store the second data and the processing results of the second data via the first computing resource, nor perform the first computing task. The release procedure of the first computing resource may also be triggered by the computing management network element, which is not limited in the present application and will not be described herein.

By the method provided by the application, the terminal device obtains the information of the first computing resource from the computing management network element by calling the computing service of the computing management network element, and the terminal device can process the second data of the first computing task through the first computing resource, so that the computing resource consumption of the terminal device for executing the first computing task is reduced, and the execution efficiency of the first computing task is improved.

In the present application, the first session may be initiated by the terminal device, and the specific establishment procedure may be referred to as follows.

Fig. 4 is a schematic flow chart of a session establishment method according to an embodiment of the present application.

Step 401, the terminal device sends a first session establishment request message to the signaling distribution network element, where the first session establishment request message is used to request to establish a first session for the terminal device.

Correspondingly, the signaling distribution network element receives a first session establishment request message from the terminal device.

The specific process of forwarding the first session establishment request message to the signaling distribution network element after the access network device receives the first session establishment request message is not limited, and is not repeated herein.

In the present application, the message name of the first session establishment request message is not limited, and for example, the first session establishment request message may also be referred to as a computing session establishment request message or the like.

The terminal device is not limited in what case the first session establishment request message is. For example, the terminal device may initiate the first session establishment if it determines to perform a first computing task, such as an upper layer application of the terminal device requesting to perform a computing task such as image rendering or image generation or video generation.

In one implementation, the first session establishment request message may include identification information of the terminal device and identification information of the computing service. The signaling distribution network element may thus determine the terminal device requesting the establishment of the first session and may determine the computing management network element providing the computing service based on the identification information of the computing service.

In one implementation, the first session establishment request message includes a session establishment NAS container (container), where the session establishment NAS container includes identification information of the first session, type information of the first session, and identification information of the terminal device, and the signaling distribution network element does not parse the computing task establishment NAS container, but forwards the computing task establishment NAS container to the computing management network element.

Step 402, the signaling distributing network element sends a second session establishment request message to the computing management network element, where the second session establishment request message is used to request to establish the first session for the terminal device.

Correspondingly, the computing management network element receives a second session establishment request message.

In one implementation, the signaling distribution network element may determine the computing management network element according to the identification information of the computing service. For example, the signaling distribution network element may determine the computing management network element according to an association relationship between the identification information of the computing management network element and the identification information of the computing service. The association relationship may be determined by a signaling distribution network element, for example, the signaling distribution network element obtains information of a computing management network element through a NAS service management network element, where the information of the computing management network element includes an association relationship between identification information of the computing management network element and identification information of a computing service.

In one implementation, the first session establishment request message includes a second session establishment request message, and the signaling distribution network element may obtain the second session establishment request message from the first session establishment request message, e.g., the second session establishment request message is included in a session establishment NAS container of the first session establishment request message.

In another implementation, the signaling distribution network element generates a second session establishment request message according to the first session establishment request message.

The second session establishment request message may include identification information of the first session, type information of the first session, identification information of the terminal device. For example, the first session establishment request message comprises a session establishment NAS container, and the signaling distribution network element may take the session establishment NAS container as part of the second session establishment request message.

The second session establishment request message may further include other information, for example, location information of the terminal device, which is not limited in the present application and will not be described herein.

Step 403, the computing management network element sends a second session establishment response message to the signaling distribution network element.

Correspondingly, the signaling distribution network element receives a second session establishment response message from the computing management network element.

The computing management network element may establish a first session with the terminal device in accordance with the second session establishment request message. In the first session establishment procedure, the computing management network element may determine at least one computing processing node for providing computing resources for computing tasks of the terminal device.

In one implementation manner, the computing management network element may select at least one computing processing node with the smallest computing load according to the computing load of each computing processing node in the plurality of computing processing nodes, so that the resource utilization rate of the computing processing nodes may be improved.

In one implementation, the second session establishment request message further includes location information of the terminal device, and the computing management network element may determine at least one computing processing node according to the location information of the terminal device. For example, the computing management network element determines the distance between each computing processing node in the plurality of computing processing nodes and the terminal device according to the position information of the terminal device, and the computing management network element selects at least one computing processing node closest to the terminal device, so that the processing time delay of the computing task can be reduced.

In one implementation, the second session establishment request message further includes session type information for the first session. And the computing management network element determines the computing processing node according to the session type information. For example, each of a plurality of computing processing nodes supports a session of one session type. The computing management network element selects at least one computing processing node of the session type indicated by the session type information, which may ensure that the computing resources provided by the computing processing node can be used.

The computing management network element may further establish a session context of the first session in the computing processing node, where the session context may include information such as quality of service flow information of the first session, identification information of the first session, type information of the first session, identification information of the terminal device, identification information of the computing service, policy information, and the like. Conditions indicated by policy information include, for example, performing an offload process on computing tasks having computing resource requirements greater than or equal to a resource threshold and latency requirements less than or equal to a latency threshold.

How policy information is determined, the application is not limited. For example, the computing management network element may determine policy information according to at least one of the number of resources of the computing processing node, the time delay of the computing processing node, the bandwidth of the computing processing node, and the location information of the terminal device.

The computing management network element may also establish an association of the computing processing node with the terminal device, the first session. If the computing management network element determines that the terminal device requests computing resources for computing tasks, the computing resources may be allocated in the computing processing node for the computing tasks of the terminal device according to the above-mentioned association relationship.

In one implementation, if the first session establishment is successful, the second session establishment response message indicates that the first session establishment is successful.

In another implementation, if the first session establishment fails, the second session establishment response message indicates that the first session establishment fails, and the second session establishment response message may also be a second session establishment rejection message. Optionally, the second session establishment response message further includes a failure cause value, which may also be referred to as a reject cause value, for indicating a cause of the failure of the first session establishment. Typically, the failure cause value may be any one of the following:

The reason value #1 is insufficient in computing resources, namely, all computing processing nodes managed by the current computing management network element cannot allocate the required computing resources for the establishment of the first session, so that the establishment request of the first session is refused;

The reason value #2, the calculation surface congestion, the current calculation management network element, because the number of the first session processed in parallel reaches the threshold value of the processing capacity, carries out the calculation surface congestion control to prevent the self congestion, thereby rejecting the establishment request of the first session;

the reason value #3, the session type does not support that the terminal device will carry the session type (e.g., graphics rendering, AI model training, etc.) in the session establishment request, but the computing management network element does not support the requested session type, so the session establishment request is denied.

In the present application, the second session establishment response message may further include information such as qos flow information of the first session, identification information of the terminal device, policy information, and the like. For example, the second session establishment response message includes a NAS container including information of the quality of service flow information of the first session, identification information of the terminal apparatus, policy information, and the like.

Step 404, the signaling distribution network element sends a first session establishment response message indicating that the first session establishment was successful.

Accordingly, the terminal device receives the first session establishment response message.

The signaling distribution network element may also establish an association of the first session, the terminal device, and the computing management network element. Thus, when the terminal device offloads the computing task to the network side, for example, when receiving the first request message from the terminal device, the signaling distribution network element can determine the computing management network element for distributing computing resources for the computing task carried by the first session of the terminal device according to the association relation.

The signaling distribution network element may generate the first session establishment response message according to the second session establishment response message, and the specific process is not described in detail.

In one implementation, if the first session establishment is successful, the first session establishment response message indicates that the first session establishment is successful.

The signaling distribution network element may determine that the first network element requests the terminal device to provide the computing service according to the identification information of the computing service in the first computing service request message.

Optionally, if the signaling distribution network element determines that the terminal device is in an idle state or inactive state, a procedure of paging the terminal device may also be initiated, and the specific paging procedure is not limited and will not be described herein.

Optionally, the second computing service request message may further include third data, where the third data is data used to perform the second computing task, for example, the second computing task is AI model training, and the third data is AI model training data.

The second computing service request message may include information such as identification information of the second computing task and identification information of the first network element, for example, the second computing service request message may include a computing service invocation NAS container.

Optionally, the terminal device initiates the establishment of the second session, step 503.

If the terminal device determines that the session corresponding to the computing service has not been established, a second session may be initiated to be established, where the second session is used to carry the computing task corresponding to the computing service, and the specific flow may refer to the foregoing description and will not be repeated herein.

Step 504, the terminal device executes the second computing task and sends the processing result of the second computing task.

The terminal device may determine the number of resources of the computing resources allocated for the second computing task, for example, determine the number of resources according to the second information, and how to determine the number of resources is not limited by the present application.

The specific process of executing the second computing task by the terminal device through the computing resource allocated to the second computing task is not limited and will not be described herein. For example, the second computing task is AI model training, and the processing result of the second computing task is a trained AI model.

Step505, the signaling distributing network element sends the processing result of the second computing task to the first network element.
