[0019] Hereinafter, the technical solutions provided in the embodiments of the present application will be described in detail through specific embodiments and their use cases with reference to the drawings.

[0020] FIG. 2 shows a schematic flowchart of a data transmission method 200 provided in an exemplary embodiment of the present application, which may be performed by a terminal, for example, by hardware and / or software implemented in the terminal, and in this embodiment, the method 200 may include the following steps S210 and S220.

[0021] At S210, computing power requirement information is determined.

[0022] Here, the computing power requirement information represents computing power resource information required when the terminal transmits and / or processes data, and the data may be data related to performing procedures such as mathematical calculations, image / photo processing, and communication transmission at an application layer or a business layer.

[0023] In this embodiment, the application scope of the computing power requirement information may include at least one of an application data flow, an application data packet, a session channel, and a terminal. Hereinafter, the computing power requirement information will be described by taking the application scope of the computing power requirement information being an application data flow, an application data packet, a session channel, and a terminal as an example.

[0024] When the scope of application of the computing power request information is an application data flow, it can be understood that the application data flow is the application granularity when transmitting the computing power request information, for example, one computing power request information includes only one corresponding computing power request information for transmitting the data flow of the target application. In contrast, the computing power request information is transmitted to the network together with the data flow identifier information of the computing power request information application, and there may be indication information indicating that the current computing power request information is only applicable to a data flow (which may also be referred to as a QoS flow, traffic flow, or bearer).

[0025] When the scope of application of the computing power request information is an application data packet, the application data packet is used as the application granularity when transmitting the computing power request information, for example, one computing power request information includes only one computing power request information corresponding to a target application data packet, whereas the computing power request information may include indication information indicating that the current computing power request information applies only to an application data packet.

[0026] When the application scope of the computing power request information is a session channel, the session channel is the application granularity when transmitting the computing power request information, for example, one computing power request information includes only one computing power request information corresponding to a target session channel, whereas the computing power request information may include indication information indicating that the computing power request information applies only to the session channel.

[0027] When the scope of application of the computing power requirement information is a terminal, when transmitting the computing power requirement information, the terminal is used as the transmission granularity, for example, a single computing power requirement information may include all requirement information required by the terminal to transmit or process data, without distinguishing between applications, session channels, application data flows, application data packets, etc. corresponding to different data, and in contrast, the computing power requirement information may include instruction information indicating that the computing power requirement information applies only to the terminal.

[0028] At S220, the computing power requirement information is sent to a first network node.

[0029] Here, the first network node may be the network side device in the above wireless communication system, or may be a network function entity such as AMF, SMF, UPF, base station (gNB), etc., and the first network node may be formed by integrating one or more network nodes / network function entities, and this embodiment does not limit this.

[0030] Regarding the above computing capability requirement information, it should be noted that in order to ensure normal data transmission and / or processing, the first network node and the terminal have a unified understanding of the computing capability requirement information, for example, a unified understanding of the determination method of the computing capability requirement information, etc.

[0031] In this embodiment, the terminal determines computing power requirement information representing computing power resource information required by the terminal when transmitting and / or processing data, and then transmits the computing power requirement information to a first network node, so that the first network node can select or map an appropriate computing power resource for the terminal according to the received computing power requirement information, thereby realizing soft convergence of cloud-networks that transmits data while performing computing functions and simultaneously performs transmission and calculation.

[0032] FIG. 3 shows a schematic flowchart of a data transmission method 300 provided in an exemplary embodiment of the present application, which may be performed by a terminal, for example, by hardware and / or software implemented in the terminal, and in this embodiment, the method 300 may include the following steps S310, S320 and S330.

[0033] At S310, computing power requirement information is determined.

[0034] Here, for the implementation procedure of S310, reference can be made to the relevant description in the above method 200. In addition, as a possible implementation form, the implementation procedure of S310 may include the following S311-S313.

[0035] In S311, a target computing requirement when the terminal performs data transmission and / or processing is determined.

[0036] Here, the target computing requirement may be the data status calculated and / or transmitted by the terminal, etc. For example, taking a business layer in the terminal as an example, the target computing requirement may be communication resources, computing resources, etc. that a network side should provide to process a business event in the business layer, and is not limited thereto.

[0037] In S312, a basic computing unit corresponding to the target computing request is obtained.

[0038] Wherein, the basic computing unit is a computing unit supported by a target network node, and the target network node may be a first network node or a network node other than the first network node.

[0039] In one implementation, the first network node can send first information to the terminal, the first information including at least one basic computing unit supported by the first network node. Optionally, the type of the basic computing unit can be basic mathematical operations (addition, subtraction, multiplication, division, etc.), convolution operations, image recognition, voice processing, video processing, Augmented Reality (AR) / Virtual Reality (VR) processing, machine learning neural network model training, etc.

[0040] In S313, the target computing request is decomposed based on the type of the basic computing unit to obtain the computing power request information.

[0041] Wherein, the computing power requirement information includes the type of the basic computing unit and the computation amount corresponding to the target computing requirement. For example, if the type of the basic computing unit is image recognition, the corresponding computation amount may be image recognition for 5 pictures, 10 pictures, ..., n pictures. If the type of the basic computing unit is convolution operation, the corresponding computation amount may be 100, 1000, ..., n convolution operations. If the type of the basic computing unit is machine learning neural network model training, the corresponding computation amount may be neural network model training for 1, 20, ..., n data sample sets.

[0042] In S320, the application layer notifies the communication layer of the computing power requirement information.

[0043] Here, referring to FIG. 4a, by executing S320, the terminal can sink the computing capability requirement information of the application layer to the communication transport layer (i.e., the communication layer), and further send the computing capability requirement information to the network side (i.e., the first network node) via the control plane or user plane on the communication transport layer.

[0044] In this case, as one possible implementation form, the implementation procedure of “notifying the computing capability requirement information to the communication layer by the application layer” described in S320 may include at least one of the following items (1)-(3).

[0045] (1) The application layer transmits the computing capability request information to the non-access stratum (NAS layer) through AT-command or other multimedia interface (MMI), where the MMI is an interface between the communication chip and the terminal device.

[0046] Here, the trigger for transmission by the AT command may include, but is not limited to, (1a) or (1b) below.

[0047] (1a) When data transmission occurs at the application layer, the scope of the computing power requirement information may be the application level or the application data flow level.

[0048] (1b) Before the terminal registers with the network, the scope of the computing capability requirement information at this time is the terminal or application.

[0049] (2) The application layer conveys the computing capability requirement information through a data packet header.

[0050] Here, when the computing power requirement information is carried by the data packet header, the computing power requirement information may be set in a scheduled field or an extension field of the data packet header.

[0051] It should be noted that the above (2) may include data packets transmitted by the control plane, and the computing power requirement information may be extended and transmitted in the header of the data packets.

[0052] (3) The application layer transmits the computing power request information to a first computing power sensing layer located above the NAS layer.

[0053] Here, the first computing capability sensing layer is a new layer introduced in the communication layer in the terminal, and one of its main functions is to support the terminal to report computing capability requirement information to the network. As shown in Figure 4b, the first computing capability sensing layer may be located above the NAS layer, whereas a second computing capability sensing layer may be introduced as a corresponding layer of the first computing capability sensing layer on the network side (e.g., the first network node, the second network node, etc.), so that the terminal can transmit the computing capability requirement information to the second computing capability sensing layer on the network side through the first computing capability sensing layer.

[0054] It should be noted that the manner in which a terminal sinks the computing capability requirement information of the application layer to the communication layer may include, but is not limited to, the above (1)-(3), and this embodiment does not limit this.

[0055] At S330, the computing capability requirement information is sent by the communication layer to a first network node.

[0056] Here, for the implementation procedure of S330, reference may be made to the relevant description of method 200. In addition, as one possible implementation form, the implementation procedure of “sending the computing capability requirement information to the first network node by the communication layer” described in S330 may include at least one of the following items (1)-(3).

[0057] (1) conveying the computing capability requirement information to the first network node via a user plane data packet;

[0058] Wherein, the scope of the computing power requirement information to be transmitted may be an application data flow or an application data packet, whereas the computing power requirement information should include an indication of the scope of the computing power requirement information, for example, a current data packet or a data flow to which the current data packet belongs.

[0059] In this embodiment, when the computing capability requirement information is carried by the data packet header, one method is to carry it using scheduled bits of the data packet header, and another method is to carry it using extended bits of the data packet header.

[0060] It should be noted that when the computing power requirement information is transmitted through a user plane data packet, the computing power of the user plane node can meet the computing requirements of the currently transmitted data packet in an automatic update manner (software that updates computing power according to computing power requirements), and the user plane node transmits in the manner of an adaptive routing algorithm, for example, selecting a next-hop network element according to the computing power requirement (e.g., the computing power requirement in the header of the current data packet) to provide computing services for the data being transmitted, and this embodiment is not limited thereto.

[0061] (2) conveying the computing capability requirement information to the first network node via a NAS message on a control plane;

[0062] Here, when the scope of application of the computing capability requirement information may be a terminal, the NAS message carrying the computing capability requirement information may be a mobility management message, such as a registration message, a location update message, a mobility registration update message, etc., an uplink NAS message dedicated to transmitting computing capability requirement information.

[0063] Furthermore, if the scope of the computing power requirement information is an application, then the NAS message carrying the computing power requirement information may be a session management message, such as a session establishment message or a session modification message, wherein the session management message is a message related to a session that transmits specific application data.

[0064] It can be understood that if the NAS message does not terminate at the first network node, the first network node may be notified by the network entity receiving the NAS message.

[0065] (3) conveying the computing capability requirement information to the first network node by a first computing capability sensing layer located above a NAS layer in the terminal;

[0066] Now, referring again to FIG. 4b, the terminal conveys computing capability requirement information to the first network node via a new layer, ie, a first computing capability sensing layer.

[0067] In one implementation, in the logical configuration shown in Figure 4b, the NAS layer and the new layer on the network side are located in the same network node (e.g., the first network node) and belong to different logical layers of the same entity, and the terminal's computing capability requirement information is transmitted to the first network node by encapsulating it in a new layer layer message in the NAS message. After receiving the NAS message, the NAS layer of the first network node forwards the encapsulated new layer layer message (computing capability requirement information) to the second computing capability sensing layer (new layer) for processing.

[0068] In another implementation, in the logical configuration shown in Figure 4c, the NAS layer and the new layer on the network side are located in different network nodes (e.g., the second network node, the first network node), belong to different logical layers of different entities, and the terminal's computing capability requirement information is encapsulated in the new layer message 1 in the NAS message and transmitted to the network side. Here, after the NAS layer of the second network node receives the NAS message 2, it encapsulates the new layer message (MSG) 2 encapsulated therein into message 3 and forwards it to the new layer layer of the first network node for processing.

[0069] In this implementation, it can be understood that the interface (message 3) between the first network node and the second network node may be an interface based on Service Based Architecture (SBA) or an interface based on classical logic, and this is not limited thereto.

[0070] In yet another implementation, in the logical configuration shown in Figure 4d, the NAS layer on the network side is located in a network node, and the terminal can connect to the first network node by establishing a user plane channel, and the terminal's computing capability requirement information is transmitted to the first network node by encapsulating it in a new layer message 1. The new layer MSG1 is transmitted to the network by the user plane as user plane data.

[0071] Corresponding to the transmission methods (1)-(3) described in S330 above, the procedure for the first network node to receive computing capability requirement information may include at least one of the following (1)-(3).

[0072] (1) Receive the computing capability requirement information carried by a user plane data packet.

[0073] (2) receiving the computing capability requirement information conveyed by a NAS message on the control plane;

[0074] (3) receiving the computing capability requirement information conveyed by a first computing capability sensing layer located above a NAS layer in the terminal;

[0075] Here, for the relevant description of the receiving method described in (1)-(3), please refer to the relevant description of the transmitting method in S330, and in order to avoid repetition, this embodiment will not describe it in detail.

[0076] Furthermore, after receiving computing power requirement information sent by the terminal, the first network node can select a target computing power resource that satisfies the computing power requirement information and / or a network element function identifier that satisfies the target computing power resource from the scheduled computing power resources, and further perform data processing and / or transmission based on the target computing power resource and / or the network element function identifier.

[0077] Here, the scheduled computing capacity resource may be pre-arranged in the first network node, or may be arranged in another network node, and at this time, the scheduled computing capacity resource is obtained by performing computing capacity registration / update on the network function according to the computing capacity registration / information sent by the network function in the first network node. For example, before selecting a target computing capacity resource that satisfies the computing capacity request information and / or a network element function identifier that satisfies the target computing capacity resource from the scheduled computing capacity resource, the first network node can receive computing capacity registration / update information sent by a network function, and perform computing capacity registration / update on the network function according to the computing capacity registration / update information.

[0078] For example, refer to Figure 4e, a network function / network function entity (e.g., NF1 shown in Figure 4e) having computing power resources needs to perform computing power resource registration in a dedicated network function 2 (e.g., NF2 shown in Figure 4e, which may be a first network node or another network node other than the first network node) when deployed in a network or booted or restarted, and the network function 2 may be a generic network function registration management entity, such as a Network Repository Function (NRF) in 5G or a network function registration management entity in 6G, and the first network node can obtain the computing power resource distribution of different network functions in the current network from NF2. NF1 performs network function registration / update and simultaneously completes the registration / update of computing power resources of the network element.

[0079] In addition, the computing power resources of the network function may be registered with a network function entity dedicated to computing power resource registration, and the network function entity may belong to the business sensing layer or the computing power sensing layer of the network, and is not limited thereto.

[0080] In one implementation, the implementation procedure of the first network node selecting a target computing power resource satisfying the computing power request information and / or a network element function (which may be understood as a data transmission node, etc.) identifier satisfying the target computing power resource from the scheduled computing power resources may be different according to different first network nodes, and can be applied to different use cases. Hereinafter, the different use cases will be described. Here, it is assumed that the first network node includes a network function selection node (e.g., a terminal registration node, a session management function node) and a network element function registration maintenance node (or a network computing power resource management node). (Use Case 1)

[0081] In the terminal registration procedure, it is assumed that the registration node selects a session management function node, at which time the registration node is responsible for the function of a network function selection node, and the terminal transmits computing capability request information to the registration node through a mobility management message (e.g., a registration message, an attach message, a TAU message, a location update message, etc.). In this way, the registration node transmits an MSG to a network element function registration maintenance node, so that the network element function registration maintenance node can select a target computing capability resource that satisfies the computing capability request information and / or a network element function identifier that satisfies the target computing capability resource, where the MSG may include information such as a network element function type (NF type, e.g., a session management function node), a slice type, etc. in addition to the computing capability request information. In this case, the network element function registration maintenance node can feed back to the registration node a session management node identifier that meets the computing capability request, can be selected, and satisfies the NF type and slice type. (Use case 2)

[0082] In the terminal session management procedure, it is assumed that the session management function node selects a gateway node, and at this time the session management function node is responsible for the function of a network function selection node, and the terminal transmits computing power request information to the session management function node through a session management message (e.g., PDU session establishment procedure, PDU session modification procedure, etc.). In this way, the session management function node transmits an MSG to a network element function registration maintenance node, so that the network element function registration maintenance node can select a target computing power resource that satisfies the computing power request information and / or a network element function identifier that satisfies the target computing power resource, where the MSG may include an NF type (e.g., a gateway node) in addition to the computing power request information, and in this case, the network element function registration maintenance node can feed back to the session management function node a gateway node identifier that matches the computing power request, is selectable, and satisfies the NF type. (Use Case 3)

[0083] In the control plane data transmission procedure, a mobility management node selects a control plane data processing node, at this time the mobility management node is responsible for the function of a network function selection node, and the UE sends computing capability request information to the mobility management node through a mobility management message (e.g., a registration message, an attach message, a TAU message, a location update message, etc.), and thus the mobility management node sends an MSG to a network element function registration maintenance node, whereby the network element function registration maintenance node can select a target computing capability resource that satisfies the computing capability request information and / or a network element function identifier that satisfies the target computing capability resource, where the MSG may include a network element function type (NF type, e.g., a control plane data processing node) in addition to the computing capability request information, and in this case, the network element function registration maintenance node can feed back to the mobility management node a control plane data processing node identifier that matches the computing capability request, is selectable, and satisfies the NF type.

[0084] Further, the first network node (eg, the network function selection node mentioned above) performs corresponding data transmission and / or calculation based on the selected target computing power resource and / or the network element function identifier satisfying the target computing power resource.

[0085] In the above procedure, during or before the data transmission procedure of the terminal, the first network node comprehensively considers the computing power requirement information of the terminal and the available computing power resources on the network side, and selects a target computing power resource or / and network function that meets the computing power requirement of the terminal to transmit data, so as to complete the data computing requirement while transmitting data, thereby effectively realizing the soft integration of cloud-network that achieves simultaneous transmission and calculation.

[0086] In addition, the first network node may further perform statistics on at least one of the received computing power requirement information, and schedule each of the network element functions and / or the computing power resources corresponding to each of the network element functions according to the statistical result and the computing power resources of each registered network element function. Here, the "scheduling" may mean increasing or decreasing the computing power resources on one network element function, or may mean scheduling the computing power resources on one network element function to another network element function for multiple network element nodes, so that the scheduled network element functions can better serve the terminal, such as performing data transmission / calculation, etc.
