[0064] In the following, first, some terms in the embodiments of the present application are explained and described, so as to facilitate understanding by those skilled in the art.

[0065] FIG. 1 shows a schematic diagram of a mobile communication network architecture, which includes terminal devices, access network devices, a signaling distribution function (SDF) network element, a NAS service management network element, a mobility management network element, a session management network element, a computing management network element, a perception management network element, an AI management network element, and a data management network element, and the like. The SDF network element, the NAS service management network element, the mobility management network element, the session management network element, the computing management network element, the perception management network element, the AI management network element, and the data management network element, and the like, can communicate through a service interface. Optionally, the terminal devices and the network elements can also communicate through the service interface.

[0066] The mobility management network element, the session management network element, the computing management network element, the perception management network element, the AI management network element, and the data management network element, and the like, can be collectively referred to as a NAS service network element, which can provide a NAS service. The NAS service can be called by the terminal device on demand, and the NAS service can also be referred to as a NAS service or a NAS function, and the like. The NAS service network element can also be referred to as a NAS service network function or a NAS service device, and the like, which is referred to as a NAS service network element hereinafter. The NAS service provided by the NAS service network element is referred to as a network side NAS service hereinafter.

[0067] The NAS service management network element is used for managing NAS service information. The NAS service information of a terminal device is used for indicating one or more NAS services that can be provided by the terminal device, the NAS service information of a NAS service network element is used for indicating one or more NAS services that can be provided by the NAS service network element, and the NAS service information corresponding to a NAS service is used for indicating at least one terminal device and / or at least one NAS service network element that can provide the NAS service. For example, the NAS service management network element can be used for registration, update, or deregistration of NAS service information. The NAS service management network element can also be used for NAS service discovery, that is, providing NAS service information of other devices or network elements to an initiator of NAS service discovery. The initiator of NAS service discovery can be a terminal device, a NAS service network element, or a signaling distribution network element.

[0068] The session management network element can be an SMF network element in a 5G communication system or a network element having the function of the SMF network element in a next-generation communication system. The session management network element can be used for providing a session management service, for example, for session management in a mobile network, such as session establishment, modification, release, etc., and can also be used for allocating an Internet protocol address for a terminal, selecting a user plane network element for transmitting data in a session, etc.

[0069] The mobility management network element can be an AMF network element in a 5G communication system or a network element having the function of the AMF network element in a next-generation communication system. The mobility management network element can be used for providing a mobility management service, for example, managing attachment or registration of a terminal device, mobility, updating a tracking area of the terminal device, etc.

[0070] The computing management network element is a control plane network element for processing a computing task and can be used for providing a computing service, for example, establishing and maintaining a computing session based on a service call of a terminal device, establishing and maintaining a computing task, and delivering policy information of network configuration. The computing service provided by the terminal device can be invoked on demand.

[0071] The perception management network element is a control plane network element for processing a perception task and can be used for providing a perception service. For example, in the process of invoking a perception service by a terminal device, the perception management network element establishes and maintains a perception session corresponding to the perception service, and delivers a perception task offloading policy of network configuration to the terminal device. The perception management network element can also invoke the perception service provided by the terminal device on demand. The perception management network element can also register, update, or deregister the perception service provided by itself to the NAS service management network element, so as to realize discovery of the perception service.

[0072] The AI management network element can be used for providing AI training and AI model computing, etc.

[0073] The data management network element can be used to provide data storage and data processing and other data services.

[0074] The signaling distribution function network element, which can also be referred to as a signaling distribution network element or a signaling distribution device, etc., can be referred to as a signaling distribution network element hereinafter. The signaling distribution network element mainly serves as a link anchor point between a terminal device and a network, and implements NAS message distribution between the terminal device and each NAS service network element, wherein the NAS message can also be referred to as NAS signaling or signaling. The signaling distribution network element can proxy terminal device discovery of a NAS service network element, construct and maintain a NAS service network element network topology, and establish a binding relationship between the terminal device and the NAS service network element. The NAS service network element network topology can indicate NAS services provided by the NAS service network element and address information of the NAS service network element. The signaling distribution function network element is different from an AMF network element in the existing network. For NAS service registration initiated by a terminal device, the signaling distribution function network element can forward a NAS message related to NAS service registration from the terminal device to a NAS service management network element. For NAS service discovery initiated by a terminal device, the signaling distribution function network element can forward a NAS message related to NAS service discovery to a NAS service management network element. For NAS service invocation initiated by a terminal device, the signaling distribution function network element selects a corresponding NAS service network element based on NAS service type information and forwards a NAS message of the terminal device to the NAS service network element. Optionally, if the terminal device is in an idle state, the terminal device can also be paged before the NAS message is forwarded to the terminal device.

[0075] It should be noted that the network element in the embodiments of the present application can also be referred to as a network function (network function, NF) or a functional entity, a device, etc. For example, the NAS service management network element can also be referred to as a NAS service management network function, etc. The names of various functions are not limited in the present application. Those skilled in the art can replace the names of the above functions with other names while performing the same functions, which all belong to the scope of protection of the present application.

[0076] In the embodiments of the present application, the access network device can be a device in a wireless network, and can also be referred to as a network device or a wireless access network device. For example, the access network device can be a radio access network (RAN) node that accesses a terminal device to a wireless network, and can also be referred to as an access network device. The access network device includes but is not limited to: a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next generation NodeB (gNB) in a 5th generation (5G) mobile communication system, an access network device in an open radio access network (O-RAN), a base station in a future mobile communication system, or an access node in a wireless fidelity (WiFi) system, etc.; or can be a module or unit that completes part of the function of the base station, for example, can be a central unit (CU), a distributed unit (DU), a central unit control plane (CU-CP) module, or a central unit user plane (CU-UP) module. The access network device can be a macro base station, or a micro base station or an indoor station, or a relay node or a donor node, etc. The specific technology and specific device form of the access network device used in the present application are not limited.

[0077] In some implementations, an access network device can include a centralized unit (CU) and a distributed unit (DU). A RAN device including a CU node and a DU node splits the protocol layers of a gNB in an NR system, with some of the protocol layers' functions being centrally controlled at the CU and the rest or remaining protocol layers' functions being distributed in the DU, with the CU centrally controlling the DU. Further, the CU can be further divided into a control plane (CU-CP) and a user plane (CU-UP). The CU-CP is responsible for control plane functions, including mainly radio resource control (RRC) and a control plane corresponding packet data convergence protocol (PDCP) (i.e., PDCP-C). The PDCP-C is mainly responsible for encryption and decryption of control plane data, integrity protection, data transmission, etc. The CU-UP is responsible for user plane functions, including mainly service data adaptation protocol (SDAP) and a user plane corresponding PDCP (i.e., PDCP-U). The SDAP is mainly responsible for processing data of a core network and mapping a flow to a bearer. The PDCP-U is mainly responsible for encryption and decryption of data plane, integrity protection, header compression, sequence number maintenance, data transmission, etc. The CU-CP and the CU-UP are connected through an El interface. The CU-CP represents the gNB to connect with the core network through an NG interface, and to connect with the DU through a control plane (i.e., Fl-C) of an Fl interface. The CU-UP connects with the DU through a user plane (i.e., Fl-U) of the Fl interface. Of course, there is also a possible implementation that the PDCP-C is also in the CU-UP.

[0078] It can be understood that in different systems, the CU (including CU-CP or CU-UP) or DU can also have different names, but those skilled in the art can understand its meaning. For example, in an open radio access network (O-RAN) system, the CU can also be referred to as an O-CU (open CU), the DU can also be referred to as an O-DU, the CU-CP can also be referred to as an O-CU-CP, and the CU-UP can also be referred to as an O-CU-UP. For the convenience of description, the CU, CU-CP, CU-UP and DU are taken as examples for description in this application. The access network device can also include an active antenna unit (AAU). The CU implements part of the functions of the gNB, and the DU implements part of the functions of the gNB. For example, the CU is responsible for processing non-real-time protocols and services, and implements the functions of the RRC layer. The DU is responsible for processing physical layer protocols and real-time services, and implements the functions of the radio link control (RLC) layer, the media access control (MAC) layer and the physical (PHY) layer. In some deployments, the CU can also be divided into a centralized unit control plane (CU-CP) node and a centralized unit user plane (CU-UP) node. Among them, the CU-CP is responsible for the control plane function, and the CU-UP is responsible for the user plane function.

[0079] The terminal device involved in the embodiments of the present application can be a wireless terminal device capable of receiving network device scheduling and indication information. The terminal device can invoke basic NAS services provided by the network side, including: access management services, mobile management services, NAS security services, etc. The terminal device can also invoke new NAS services provided by the network side, including: session management services, policy control services, computing services, sensing services, artificial intelligence (AI) services, data services, artificial intelligence agent communication services, digital identity services, etc. The terminal device can also provide NAS services, and the network side can invoke the NAS services provided by the terminal device as needed. For example, the NAS services provided by the terminal device can include computing services, sensing services, or artificial intelligence services, etc.

The RAN and the signaling distribution network element both transparently transmit the service-based NAS message. The service-based NAS message can be encoded in the form of an open application programming interface (open API), which is more suitable for the interaction mechanism of the NAS service call.

[0082] On the terminal device side, the protocol stack structure can include a service-based NAS layer, hypertext transfer protocol (HTTP) / 2 or HTTP / 3, transmission control protocol (TCP) / quick UDP internet connections (QUIC), an internet protocol (IP) layer, a layer 2 (L2), and a layer 1 (L1). The L1 can include a physical (PHY) layer, etc. The L2 can include a service data adaptation protocol (SDAP) layer, a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, and a media access control (MAC) layer, etc. The service-based NAS layer is mainly to implement NAS services, for example, to implement basic NAS services (such as access management services and mobile management services) and new NAS services (such as computing services, sensing services, and artificial intelligence services).

[0083] The protocol layer between the terminal device and the RAN can be an access network (AN) protocol layer, for example, including L1 and L2 related protocol layers, which is not limited in the present application.

[0084] The protocol layer between the RAN and the signaling distribution network element can be a protocol layer between the RAN and the core network (RAN-CN protocol layer), which is not limited in the present application.

[0085] The protocol layer between the signaling distribution network element and the NAS service network element can be a service-based interface protocol, for example, including HTTP / 2 or HTTP / 3, transport layer security (TLS), TCP / QUIC, IP, L2, L1, etc.

[0086] The above protocol stack is only an example and should not be construed as a limitation. For example, the protocol stack can have fewer layers or more layers than the example.

[0087] In combination with the foregoing description, in the present application, the NAS function can be serviced, and the terminal device and the NAS service network element can register the NAS service provided by themselves as needed to achieve flexible mutual calling of the NAS service as needed, which will be described in detail below.

[0088] In the present application, the names of various messages and various information are only examples, and as the network architecture evolves and new business scenarios appear, the names of the messages or information can change accordingly, but the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0089] When the method provided by the present application is applied to the system shown in FIG. 1, the terminal device can be a terminal device or a chip or module in the terminal device in FIG. 1; the signaling distribution network element can be a chip or module in the signaling distribution function network element in FIG. 1; and the computing management network element can be a chip or module in the computing management network element in FIG. 1.

[0090] As shown in FIG. 3, it is a flow diagram of a communication method provided by an embodiment of the present application.

[0091] Step 301: The terminal device sends a first request message to the signaling distribution network element.

[0092] Correspondingly, the signaling distribution network element receives the first request message.

[0093] In the present application, the terminal device can 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 access network device forwards the first request message to the signaling distribution network element, and the specific process is not limited by the present application, which will not be described here.

[0094] In the present application, the message name of the first request message is not limited, for example, the first request message can also be called a computing task resource request message or a computing task establishment request message.

[0095] The application does not limit when the terminal device sends the first request message. For example, the terminal device performs a first computing task, and the terminal device determines to unload the first computing task to the network for execution according to policy information, and then the first request message can be sent. The policy information can be preset or configured by the network side. For example, before step 301, the computing management network element can send the policy information to the terminal device through the signaling distribution network element. The policy information is used to indicate the condition for the terminal device to send data corresponding to the computing task to the network for processing, which can be understood as the condition for the policy information to indicate that the data corresponding to the computing task is unloaded to the network for execution. For example, the condition indicated by the policy information includes that the computing task performs unloading processing when the requirement for computing resources is greater than or equal to a resource threshold, and the requirement for latency is less than or equal to a latency threshold. The policy information can also be referred to as a computing task unloading policy, and the application does not limit the name of the policy information. The application does not limit the condition indicated by the policy information, which is not described here.

[0096] In the application, the first computing task can be a task requested by an upper layer application (for example, an application program in the terminal device) of the terminal device to execute. In an implementation manner, the first computing task includes processing first data. For example, the first data is image data, and the first computing task can include image rendering or image compression on the image data, or the first computing task can include AI image generation according to the image data; the first data is video data, and the first computing task can include AI video generation according to the video data; the first data is voice data, and the first computing task can include audio compression on the audio data.

[0097] In the application, the first request message is used to request to invoke a computing service. The first request message can also be used to instruct the signaling distribution network element to send a second request message to the computing management network element, and the second request message is used to request to allocate computing resources for the first computing task. In an implementation manner, the first request message includes identification information of the computing service; the identification information of the computing service is used for the signaling distribution network element to send the second request message to the computing management network element. Optionally, the first request message includes the second request message.

[0098] The computing resources include hardware resources used for processing computing tasks, for example, the computing resources include at least one of central processing unit (CPU) resources, graphics processing unit (GPU) resources, and storage resources. The application does not limit the implementation manner of the computing resources.

[0099] The first computing task can be a computing task corresponding to the computing service, and the computing service can correspond to multiple computing tasks.

[0100] Optionally, in the present application, the first request message can also be used to request allocation of computing resources for the first computing task.

[0101] The first request message can further include identification information of a first session. The first session is a session established between the terminal device, the computing management network element, and the computing processing node, and is a session used to carry the computing task. It can be understood that the first session is a user plane channel established between the terminal device and the computing management network element, and the first session can support offloading of the computing task and delivery of the computing result of the computing task. For example, the first session can be a protocol data unit (PDU) session; the first session can be a session similar to the PDU session, for example, the first session can be referred to as a computing session. One first session can correspond to one or more computing tasks, that is, one first session can carry one or more computing tasks, and multiple computing tasks can have the same service requirement and service attribute, such as image rendering computing tasks initiated by multiple applications, which can be carried on the same session.

[0102] The first session can be initiated by the terminal device to establish, and the specific process of establishing the first session is not limited in the present application, for example, reference can be made to the process shown in FIG. 4 below. The establishment process of the first session can be completed before step 301.

[0103] In the present application, the first request message can 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, or computing resource requirement information of the terminal device, the computing resource requirement information is used to indicate second computing resources, the second computing resources are computing resources expected to be obtained by the terminal device, and the computing resource requirement information can indicate resource quantity information of the second computing resources. The task type information of the first computing task can indicate the task type of the first computing task, for example, 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 can also indicate the computing resources required by the first computing task, the resource quantity of the computing resources required by computing tasks of different task types is different, and an association relationship between the task type of the computing task and the resource quantity of the computing resources required by the computing task can be established in advance, so that the computing management network element can determine the resource quantity of the computing resources required by the computing task according to the task type of the computing task.

[0104] In an implementation form, the first request message further comprises a compute task establishment NAS container, the compute task establishment NAS container comprising 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 compute task, task type information of the first compute task, and compute resource requirement information, the signaling distribution network element not analyzing the compute task establishment NAS container but forwarding the compute task establishment NAS container to the compute management network element.

[0105] The identification information of the first session is used to identify the first session, and the type information of the first session is used to indicate the type of the first session. For example, the type of the first session can be an IP-based PDU session or an Ethernet PDU session, and the type of the first session can also be an AI task session or an image task session.

[0106] In the IP-based PDU session, data is transmitted in the form of an IP packet. In the Ethernet PDU session, data is transmitted in the form of an Ethernet frame.

[0107] The AI task session refers to a session used to carry a compute task related to an AI task, and the image task session refers to a session used to carry a compute task related to an image task. In the present application, the first session can also have other types, which are not limited.

[0108] The identification information of the first compute task can be used to indicate the first compute task. The identification information of the first compute task and the type information of the first compute task can be the same information, i.e., the identification information or the type information of the first compute task can indicate the first compute task and the type of the first compute task.

[0109] Step 302: The signaling distribution network element sends a second request message to the compute management network element. The second request message is used to request allocation of compute resources for the first compute task.

[0110] Correspondingly, the compute management network element receives the second request message from the signaling distribution network element.

[0111] Optionally, before step 301, the compute management network element performs NAS service registration in the NAS service management network element. In the NAS service registration process, the compute management network element registers the NAS service it can provide as a compute service in the NAS service management network element.

[0112] The specific content of the above NAS service registration process is not limited in the present application and will not be described here.

[0113] Optionally, before step 301, the signaling distribution network element can 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 the 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 indicate that the computing management network element provides the computing service, and the information of the computing management network element can also be referred to as the 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 the 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 can also include the address information of the computing management network element (for example, the address information is a fully qualified domain name (FQDN) or an IP address). The identification information of the computing management network element is used to identify the computing management network element and / or the type of the computing management network element, which can also be referred to as the type information of the computing management network element; the identification information of the computing service can be replaced by the service name information or the index information of the computing service, and the identification information of the computing service is used to identify the computing service.

[0114] The specific content of the above process of obtaining the information of the computing management network element is not limited in the present application, and will not be described here.

[0115] In the present application, the message name of the second request message is not limited, for example, the second request message can also be referred to as a computing task resource request message or a computing task establishment request message.

[0116] According to the first request message, the signaling distribution network element can determine that the terminal device requests to invoke the computing service, and can also determine to send the second request message to the computing management network element. The present application does not limit how the signaling distribution network element determines the computing management network element, and the following gives several possible implementation manners.

[0117] In one implementation manner, the first request message includes the identification information of the computing service, and the signaling distribution network element can determine the computing management network element according to the identification information of the computing service in the first request message.

[0118] For example, the signaling distribution network element can determine the computing management network element according to the 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 can obtain the information of the computing management network element through the NAS service management network element, and the information of the computing management network element can indicate the association relationship.

[0119] In this implementation manner, after the signaling distribution network element determines the computing management network element, the terminal device can also establish a first session to transmit data corresponding to the first computing task to the network side through the first session. The specific process of establishing the first session can be referred to the description below.

[0120] In another implementation, the first request message comprises identification information of the computing service and identification information of the first session, and the signaling distribution network element can determine the computing management network element according to the identification information of the first session and the identification information of the computing service.

[0121] For example, the signaling distribution network element can 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 can determine the association relationship in the process of establishing the first session, and the specific process of establishing the first session can be referred to the description below, which will not be repeated here. In this implementation, the process of establishing the first session can be located before step 301.

[0122] In this implementation, 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 can directly transmit the data corresponding to the first computing task to the network side through the first session.

[0123] In this application, the second request message can comprise at least one of the identification information of the first session, the type information of the first session, the identification information of the terminal device, the task type information of the first computing task and the computing resource requirement information. For example, the first request message comprises a computing task establishment NAS container, and the signaling distribution network element can take the computing task establishment NAS container as a part of the second request message, that is, the second request message comprises the computing task establishment NAS container.

[0124] The second request message can also comprise other information, which is not limited in this application and will not be repeated here.

[0125] Step 303: The computing management network element allocates the first computing resource for the first computing task according to the second request message.

[0126] In this application, the computing resource can be provided by the computing processing node, and how the computing management network element determines the computing processing node for providing the first computing resource is not limited in this application, and an example is given below.

[0127] Before step 303, the first session can be established between the terminal device and the computing management network element. In the process of establishing the first session, the computing management network element can determine at least one computing processing node, and how the computing management network element determines the at least one computing processing node can be referred to the description below, which will not be repeated here.

[0128] The computing management network element can establish a management relationship between at least one computing processing node and the first session, and the at least one computing processing node can be used to provide computing resources for a computing task of the first session.

[0129] In an implementation manner, the second request message comprises identification information of the first session. After obtaining the second request message, the computing management network element can determine at least one computing processing node associated with the first session according to the identification information of the first session. The computing management network element can select one or more computing processing nodes from the at least one computing processing node; the one or more computing processing nodes can be part or all of the at least one computing processing node. The computing management network element does not limit how to select the one or more computing processing nodes. For example, the computing management network element can select a computing processing node with a computing load less than or equal to a load threshold from the at least one computing processing node.

[0130] For another example, one computing processing node can support at least one computing task, for example, one computing processing node supports an AI model training task, and another computing processing node supports 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.

[0131] The computing management network element can allocate a first computing resource for the first computing task from computing resources provided by the computing processing node. The number of computing processing nodes providing the first computing resource for the first computing task is not limited, and one or more computing processing nodes can provide the first computing resource for the first computing task. The one or more computing processing nodes can be selected from the at least one computing processing node associated with the first session.

[0132] In the present application, the computing management network element does not limit how to determine the first computing resource.

[0133] In an implementation, the second request message comprises at least one of the following information: type information of the first computing task, or computing resource requirement information of the terminal device. The first computing resource can be determined according to at least one of the task type information and the computing resource requirement information of the first computing task. For example, the task type information of the first computing task can indicate a task type of the first computing task, and the required computing resource quantity of computing tasks of different task types is different, and the computing management network element can determine the required computing resource quantity of the terminal device for executing a computing task corresponding to the task type according to the task type information, so as to allocate the first computing resource of the corresponding resource quantity. For another example, the computing management network element can determine the second computing resource according to the computing resource requirement information, so as to determine the first computing resource according to the second computing resource, for example, the resource quantity of the first resource allocated by the computing management network element is greater than or equal to the resource quantity of the second resource.

[0134] The above is only an example, and when determining the first computing resource, the computing management network element can also not consider the task type information of the first computing task and the second computing resource, but determine the first computing resource according to the actual resource quantity that can be provided by the computing processing node; or, when determining the first computing resource, the computing management network element can also determine the first computing resource according to other parameters, which are not limited by the present application.

[0135] Step 304: The computing management network element sends information of the first computing resource to the signaling distribution network element.

[0136] Correspondingly, the signaling distribution network element receives the information of the first computing resource from the computing management network element.

[0137] For example, the computing management network element sends a second response message to the signaling distribution network element; the second response message comprises the information of the first computing resource.

[0138] In the present application, the information of the first computing resource can indicate the resource quantity of the first computing resource, and can also indicate the computing processing node to which the first computing resource belongs. The unit of the resource quantity of the first computing resource can be floating point operations per second (FLOPS), and the present application is not limited thereto. For example, the information of the first computing resource indicates that the resource quantity of the first computing resource is 2000 FLOPS.

[0139] Step 305: The signaling distribution network element sends the information of the first computing resource to the terminal device.

[0140] Correspondingly, the terminal device receives the information of the first computing resource from the computing management network element through the signaling distribution network element.

[0141] For example, the signaling distribution network element sends a first response message to the terminal device, and the first response message comprises information of the first computing resource.

[0142] In an implementation manner, the first response message can further comprise identification information of the first session, identification information of the first computing task, and the like. For example, the first response message comprises a NAS container, and the NAS container comprises the identification information of the first session, the identification information of the first computing task, and the information of the first computing resource, and the like.

[0143] Optionally, if the terminal device determines that the quantity of the first computing resource is less than the quantity of resources required to process the first computing task, the terminal device can request the computing resource again, and details are not described herein again.

[0144] In step 306, the terminal device sends second data to the computing processing node according to the information of the first computing resource. The second data is part or all of the first data.

[0145] In the present application, the terminal device can determine the quantity of the second data according to the first computing resource. Optionally, the second data is the maximum quantity of data that can be processed by the first computing resource. For example, the terminal device determines the quantity of data processed by the first computing resource, and the quantity of the second data can be the quantity of data processed by the first computing resource. For example, the terminal device determines that the first computing resource can process half of the first data, and then the second data can be half of the first data.

[0146] The terminal device can send the second data to the computing processing node, and the computing processing node executes the first computing task according to the second data. For example, the terminal device can send a computing task offloading request message to the computing processing node through the first session, and the computing task offloading request message is used to request execution of the first computing task according to the second data. The computing task offloading request message can comprise the second data. The computing task offloading request message can further comprise identification information of the first computing task, identification information of the first session, and the like.

[0147] Optionally, the terminal device can not directly send the computing task offloading request message to the computing processing node, and the computing task offloading request message can be forwarded to the computing processing node through an access network device or the like. Details are not described herein again.

[0148] Optionally, in step 307, the computing processing node sends a processing result of the second data.

[0149] Correspondingly, the terminal device receives the processing result of the second data from the computing processing node.

[0150] The processing result of the second data is determined according to the second data.

[0151] For example, the second data is image data, the first computing task is image rendering, and the processing result of the second data can be a rendered image; the second data is image data, the first computing task is video generation, and the processing result of the second data can be a video generated according to the image data; the second data is image data, the first computing task is image generation, and the processing result of the second data can 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 can be a trained AI model. The above are only examples, and the processing result of the second data can also have other forms, which are not limited by the present application.

[0152] In an implementation manner, the computing processing node can send a computing task offloading response message, and the computing task offloading response message includes the processing result of the second data. The computing task offloading response message can also include other information, which is not limited by the present application.

[0153] The terminal device can also determine the processing result of the first computing task according to 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 processed by the terminal device locally to obtain the processing result of the first computing task. The third data is data other than the second data in all data processed by the first computing task.

[0154] Optionally, after obtaining the processing result, the terminal device can also release the first computing resource. For example, the terminal device sends a first resource release request message to the signaling distribution network element, and the first resource release request message is used to request to release the first computing resource. Correspondingly, the signaling distribution network element receives the 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, and the second resource release request message is used to request to release the first computing resource. The first resource release request message and the second resource release request message can include identification information of the first session, identification information of the first computing task, and information of the first computing resource, and the like, which are not limited by the present application. The computing management network element receives the second resource release request message, and can instruct the computing processing node to release the first computing resource allocated for the first computing task. The computing processing node can no longer save the second data and the processing result of the second data through the first computing resource, and can no longer execute the first computing task. The release process of the first computing resource can also be triggered by the computing management network element, which is not limited by the present application, and will not be described here.

[0155] By the method provided in the application, the terminal device invokes the computing service of the computing management network element to obtain the information of the first computing resource from the computing management network element, and the terminal device can process the second data of the first computing task by using the first computing resource, thereby reducing the computing resource consumption of the terminal device in executing the first computing task and improving the execution efficiency of the first computing task.

[0156] In the application, the first session can be initiated by the terminal device, and the specific establishment process can refer to the following.

[0157] As shown in FIG. 4, it is a flowchart of a session establishment method provided in an embodiment of the application.

[0158] Step 401: The terminal device sends a first session establishment request message to the signaling distribution network element; the first session establishment request message is used to request to establish a first session for the terminal device.

[0159] Correspondingly, the signaling distribution network element receives the first session establishment request message from the terminal device.

[0160] The terminal device can send the first session establishment request message to the signaling distribution network element through the access network device, that is, the access network device forwards the first session establishment request message to the signaling distribution network element after receiving the first session establishment request message, and the specific process is not limited in the application and will not be described here.

[0161] In the application, the message name of the first session establishment request message is not limited, for example, the first session establishment request message can also be referred to as a computing session establishment request message, etc.

[0162] The application does not limit the conditions under which the terminal device sends the first session establishment request message. For example, the terminal device determines to execute a first computing task, such as the upper-layer application of the terminal device requesting to execute an image rendering or image generation or video generation computing task, and then the first session can be initiated.

[0163] In an implementation manner, the first session establishment request message can include the identification information of the terminal device and the identification information of the computing service. In this way, the signaling distribution network element can determine the terminal device that requests to establish the first session, and can determine the computing management network element that provides the computing service according to the identification information of the computing service.

[0164] In an implementation manner, the first session establishment request message includes a session establishment NAS container, the session establishment NAS container includes the identification information of the first session, the type information of the first session, and the identification information of the terminal device, the signaling distribution network element does not analyze the computing task establishment NAS container, but forwards the computing task establishment NAS container to the computing management network element.

[0165] Step 402: The signaling distribution network element sends a second session establishment request message to the computing management network element, and the second session establishment request message is used to request to establish a first session for the terminal device.

[0166] Correspondingly, the computing management network element receives the second session establishment request message.

[0167] In an implementation manner, the signaling distribution network element can determine the computing management network element according to the identification information of the computing service. For example, the signaling distribution network element can 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 can be determined by the signaling distribution network element, for example, the signaling distribution network element obtains the information of the computing management network element through the NAS service management network element, and the information of the computing management network element includes the association relationship between the identification information of the computing management network element and the identification information of the computing service.

[0168] In an implementation manner, the first session establishment request message includes the second session establishment request message, and the signaling distribution network element can obtain the second session establishment request message from the first session establishment request message, for example, the second session establishment request message is included in a session establishment NAS container of the first session establishment request message.

[0169] In another implementation manner, the signaling distribution network element generates the second session establishment request message according to the first session establishment request message.

[0170] The second session establishment request message can include the identification information of the first session, the type information of the first session, and the identification information of the terminal device. For example, the first session establishment request message includes a session establishment NAS container, and the signaling distribution network element can take the session establishment NAS container as a part of the second session establishment request message.

[0171] The second session establishment request message can also include other information, for example, the location information of the terminal device, which is not limited in the present application and will not be described here.

[0172] Step 403: The computing management network element sends a second session establishment response message to the signaling distribution network element.

[0173] Correspondingly, the signaling distribution network element receives the second session establishment response message from the computing management network element.

[0174] The computing management network element can establish the first session with the terminal device according to the second session establishment request message. During the first session establishment process, the computing management network element can determine at least one computing processing node, and the at least one computing processing node is used to provide computing resources for the computing task of the terminal device.

[0175] In an implementation, the computing management network element can select at least one computing processing node with the least computing load according to the computing load of each computing processing node in the plurality of computing processing nodes, so as to improve the resource utilization of the computing processing node.

[0176] In an implementation, the second session establishment request message further comprises location information of the terminal device, and the computing management network element can determine the 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 location information of the terminal device; and the computing management network element selects at least one computing processing node closest to the terminal device, so as to reduce the processing delay of the computing task.

[0177] In an implementation, the second session establishment request message further comprises session type information of the first session. The computing management network element determines the computing processing node according to the session type information. For example, each computing processing node in the plurality of computing processing nodes supports a session of a session type. The computing management network element selects at least one computing processing node of the session type indicated by the session type information, so as to ensure that the computing resource provided by the computing processing node can be used.

[0178] The computing management network element can further establish a session context of the first session in the computing processing node, which can comprise service quality 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, and policy information. For example, the policy information indicates that the computing task performs offloading processing when the requirement for computing resource is greater than or equal to a resource threshold value or the requirement for delay is less than or equal to a delay threshold value.

[0179] The application does not limit how the policy information is determined. For example, the computing management network element can determine the policy information according to at least one of the resource quantity of the computing processing node, the delay of the computing processing node, the bandwidth of the computing processing node, and the location information of the terminal device.

[0180] The computing management network element can further establish an association relationship between the computing processing node and the terminal device and the first session. If the computing management network element determines that the terminal device requests computing resource for the computing task, the computing resource can be allocated to the computing task of the terminal device in the computing processing node according to the association relationship.

[0181] In an implementation, if the first session is established successfully, the second session establishment response message indicates that the first session is established successfully.

[0182] In another implementation, if the first session establishment fails, the second session establishment response message indicates the first session establishment failure, and the second session establishment response message can also be a second session establishment rejection message. Optionally, the second session establishment response message further includes a failure cause value, which can also be referred to as a rejection cause value, and the failure cause value is used to indicate the cause of the first session establishment failure. Typically, the failure cause value can be any of the following cause values:

[0183] Cause value #1: insufficient computing resources: all computing processing nodes managed by the current computing management network element have no computing resources required for the establishment of the first session, so the establishment request of the first session is rejected;

[0184] Cause value #2: computing plane congestion: the current computing management network element rejects the establishment request of the first session because the number of parallel processing first sessions reaches the threshold of its processing capacity, and in order to prevent itself from being congested, the computing management network element performs computing plane congestion control;

[0185] Cause value #3: session type not supported: the terminal device carries a session type (such as: 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 establishment request of the session is rejected.

[0186] In this application, the second session establishment response message can also include the service quality flow information of the first session, the identification information of the first session, the identification information of the terminal device, and the policy information. For example, the second session establishment response message includes a NAS container, and the NAS container includes the service quality flow information of the first session, the identification information of the first session, the identification information of the terminal device, and the policy information.

[0187] Step 404: The signaling distribution network element sends a first session establishment response message; the first session establishment response message indicates that the first session establishment is successful.

[0188] Correspondingly, the terminal device receives the first session establishment response message.

[0189] The signaling distribution network element can also establish an association relationship between the first session and the computing management network element of the terminal device. In this way, when the terminal device offloads a computing task to the network side, for example, receives a first request message from the terminal device, the signaling distribution network element can determine the computing management network element that allocates computing resources for the computing task of the first session of the terminal device according to the association relationship.

[0190] The signaling distribution network element can generate the first session establishment response message according to the second session establishment response message, and the specific process is not described again.

[0191] In one implementation, if the first session is successfully established, the first session establishment response message indicates that the first session is successfully established.

[0192] In another implementation, if the first session is unsuccessfully established, the first session establishment response message indicates that the first session is unsuccessfully established. Optionally, the first session establishment response message further comprises a failure cause value, which is used to indicate a cause of the failure of the first session establishment.

[0193] In the present application, the first session establishment response message can further comprise service quality flow information of the first session, identification information of the first session, identification information of the terminal device, policy information, and the like. For example, the second session establishment response message comprises a NAS container, and the first session establishment response message can comprise the NAS container. The terminal device can save the service quality flow information, the policy information, and the like of the first session.

[0194] Optionally, based on a requirement of the computing task processing, the terminal device or the computing management network element can initiate a modification procedure of the first session. For example, the network side computing resource changes, and the network needs to update the policy information. The specific modification procedure is not limited in the present application and will not be described here.

[0195] Optionally, after the required computing task processing is completed, the terminal device or the computing management network element can initiate a release procedure of the computing session, and the computing management network element and the computing processing node release the corresponding computing resource. The specific procedure is not limited in the present application and will not be described here.

[0196] Through the above procedure, the terminal device can request to establish the first session. The above is only an example, and other procedures for establishing the first session can also exist, which are not limited in the present application.

[0197] The above describes that the terminal device executes the computing task through the computing resource allocated by the network side. In the present application, the network side can also execute the computing task of the network side through the computing resource of the terminal device, and examples are given below.

[0198] As shown in FIG. 5, it is a flow diagram of a communication method provided by an embodiment of the present application.

[0199] Step 501: a first network element sends a first computing service request message; the first computing service request message is used to request to allocate a computing resource for the first network element.

[0200] Correspondingly, a signaling distribution network element receives the first computing service request message. The first network element can be a network side network element, for example, the first network element is a computing management network element.

[0201] In an implementation, the first network element determines that the second computing task is to be executed by the computing resource of the terminal device, and the first computing service request message can be sent. The second computing task can be a computing task corresponding to the computing service, for example, the second computing task can be an AI model training or image rendering or image generation or video generation task.

[0202] Optionally, before the first network element sends the first computing service request message, the terminal device can be determined to be able to provide the computing service, that is, the terminal device can use the computing resource of the terminal device to execute a computing task corresponding to the computing service on the network side. The specific process is not limited in the present application and will not be described here.

[0203] The first computing service request message can include identification information of the terminal device, identification information of the first network element, identification information of the second computing task, and identification information of the computing service, and the like.

[0204] Optionally, the first computing service request message can further include third data, and the third data is data used for executing the second computing task; for example, the second computing task is AI model training, and the third data is AI model training data.

[0205] Optionally, the first computing service request message can further include second information, and the second information is used to indicate a required resource quantity of the second computing task.

[0206] The first computing service request message can further include a computing service calling NAS container, and the computing service calling NAS container includes identification information of the second computing task and identification information of the first network element, and the like.

[0207] Step 502: The signaling distribution network element sends a second computing service request message to the terminal device; the second computing service request message is used to request allocation of a computing resource for the first network element.

[0208] Correspondingly, the terminal device receives the second computing service request message.

[0209] The signaling distribution network element can generate the second computing service request message according to the first computing service request message, and the specific process is not limited in the present application.

[0210] The signaling distribution network element can determine to send the second computing service request message to the terminal device according to the identification information of the terminal device in the first computing service request message. The signaling distribution network element can 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.

[0211] Optionally, if the signaling distribution network element determines that the terminal device is in an idle state or a non-activated state, the signaling distribution network element can further initiate a process of paging the terminal device, and the specific paging process is not limited in the present application and will not be described here.

[0212] Optionally, the second computing service request message can further include third data, the third data being data used for executing the second computing task; for example, the second computing task is AI model training, and the third data is AI model training data.

[0213] Optionally, the second computing service request message can further include second information, the second information being used for indicating a quantity of resources required by the second computing task.

[0214] The second computing service request message can include identification information of the second computing task and identification information of the first network element, and the like, for example, the second computing service request message can include a computing service call NAS container.

[0215] Optionally, in step 503, the terminal device initiates establishment of a second session.

[0216] If the terminal device determines that a session corresponding to the computing service has not been established, establishment of the second session can be initiated, the second session being used for carrying a computing task corresponding to the computing service. The specific process can be referred to the foregoing description, and will not be described here again.

[0217] In step 504, the terminal device executes the second computing task and sends a processing result of the second computing task.

[0218] The terminal device can determine a quantity of resources of the computing resources allocated for the second computing task, for example, the quantity of resources is determined according to the second information. How to determine is not limited in the present application.

[0219] The terminal device executes the second computing task through the computing resources allocated for the second computing task. The specific process of executing the second computing task is not limited in the present application and will not be described here again. For example, the second computing task is AI model training, and the processing result of the second computing task is a trained AI model.

[0220] In step 505, the signaling distribution network element sends the processing result of the second computing task to the first network element.

[0221] Through the above process, the first network element can execute the second computing task through the computing resources allocated by the terminal device, so that the resource load of the network side can be reduced, and the execution efficiency of the computing task can be improved.
