[0101] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The following related technologies can be combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0102] To facilitate a better understanding of the embodiments of the present application, the relay connection establishment process related to the present application is described. Specifically, as shown in Figure 2, the relay connection can be performed by the following entity devices: remote UE (Remote UE), UE to network relay UE (UE-to-NW Relay UE), Next Generation Radio Access Network (NG-RAN), Access and Mobility Management Function (AMF), Session Management Function (SMF), User Plane Function (UPF), Non-3GPP Inter Working Function (N3IWF), where the connection between the remote UE and the relay UE is layer 3 (layer3, L3).

[0103] Specifically, as shown in FIG2 , in step 1 , service authorization and configuration are performed for the 5G Proximity-based Services (ProSe) L3 relay UE, and service authorization and configuration are performed for the 5G ProSe L3 remote UE.

[0104] 2 , in step 2, the 5G ProSe L3 remote UE performs discovery of the 5G ProSe L3 relay UE. As part of the discovery process, the 5G ProSe L3 remote UE learns about the connection services provided by the 5G ProSe L3 relay UE.

[0105] Specifically, as shown in Figure 2, in step 3, the 5G ProSe L3 remote UE selects a 5G ProSe L3 relay UE and establishes a connection for unicast mode communication. If there is no protocol data unit (PDU) session associated with the relay service code (Relay Service Code) or a new PDU session is required for relaying, the 5G ProSe L3 relay UE initiates a new PDU session establishment process for relaying before completing the PC5 connection establishment.

[0106] The network determines the PDU session to be established for relaying traffic and then generates Quality of Service (QoS) rules and QoS flow-level QoS parameters at the 5G ProSe L3 relay UE. The 5G ProSe L3 relay UE determines the PDU session type for relaying. In addition, the relay UE can also establish a PDU session that can be used to perform relay services for the far-end UE.

[0107] To facilitate a better understanding of the embodiments of the present application, the model segmentation-based reasoning method related to the present application is explained.

[0108] Model splitting is the most important feature of artificial intelligence (AI) reasoning. Specifically, in convolutional neural networks (CNNs) used for image recognition, such as the AlexNet model, different model split points can correspond to different terminal computing layers and data transmission volumes. For example, as shown in Figure 3, the overall trend is that the more layers a terminal calculates, the less intermediate data needs to be transmitted to a network server (such as an application server). In other words, when the terminal's computing power is low (for example, due to low battery), the application server can change the split point to allow the terminal to calculate fewer layers, while increasing the data rate in the Uu interface to transmit the higher load of intermediate data to the network.

[0109] However, sometimes, due to radio resource limitations, it's impossible to increase the data rate. In this case, terminals with lower computing power need to offload computing tasks to nearby terminals (such as relay terminals, which provide computing services), allowing the nearby terminals to send the calculated data to the network. Therefore, offloading workloads through direct device connections can relieve the computing load of the original terminal, while not necessarily increasing the data rate of the Uu interface, thereby achieving more ideal results.

[0110] In order to facilitate a better understanding of the embodiments of the present application, the problems solved by the present application are explained.

[0111] Remote UEs can access the network through relay UEs. Relay UEs can provide not only communication services but also computing services (i.e., proximity computing services). "Proximity computing services" means that relay UEs can not only provide relay communication services but also provide computing power to perform tasks and send the results to network servers (e.g., application servers).

[0112] However, how the relay terminal (Relay UE) implements proximity computing services is a problem that needs to be solved.

[0113] Based on the above problems, the present application proposes a wireless communication solution. When the first terminal accesses the network through the second terminal and the second terminal supports proximity computing services, for the first service, the second terminal can share part of the computing tasks of the first terminal, that is, the second terminal can use the side link between the second terminal and the first terminal to realize work task offloading based on proximity services, thereby reducing the computing load of the first terminal and optimizing the computing and transmission efficiency of the first service.

[0114] In an embodiment of the present application, a first terminal (such as UE-A) accesses a network through a second terminal (such as UE-B), and the second terminal (such as UE-B) supports proximity computing services. Specifically, "proximity computing services" means that the second terminal (such as UE-B) can not only provide relay communication services, but also provide computing power to provide computing services for a certain task, and send the calculation results to a network server (such as an application server). The following describes the proximity computing services provided by the second terminal (such as UE-B) through specific embodiments.

[0115] UE-A is using an AI model (such as AlexNet) for image recognition. As shown in Figure 3, the application server can predetermine five candidate segmentation points, which are respectively recorded as segmentation point 0 (cloud-based inference), segmentation point 1 (after pooling layer 1), segmentation point 2 (after pooling layer 2), segmentation point 3 (after pooling layer 5), and segmentation point 4 (device-based inference). The corresponding intermediate data sizes (such as the approximate output data size) and uplink data transmission rates (required UL data rate) of the five candidate segmentation points can be shown in Table 1. Fewer calculation layers means less workload for UE-A.

[0116] Table 1

[0117]

[0118] 1. As shown in Figure 4, UE-A is using the Alexnet model for image recognition and selecting split point 3 for AI inference. This means that the intermediate data per frame per second is 0.02 MByte, and the uplink data transmission rate is 4.8 Mbit / s. Specifically, the end-to-end service latency (including image recognition latency and intermediate data transmission latency) is 1 second. This means that the time it takes UE-A to perform the computational tasks for layers 1-15 of the Alexnet model + the time it takes to transmit the data related to the computational tasks for layers 1-15 of the Alexnet model + the time it takes the application server to perform the computational tasks for layers 16-24 of the Alexnet model = 1 second.

[0119] 2. When the battery of UE-A is low, UE-A cannot undertake the heavy workload of the AlexNet model (i.e., the computational tasks of layers 1-15 of the AlexNet model locally).

[0120] 3. UE-A finds that UE-B (such as Customer Premise Equipment (CPE)) which has installed the same model (i.e., AlexNet model) is willing to share the computing task from UE-A.

[0121] Specifically, as shown in Figure 5, UE-A establishes a sidelink (also known as a direct connection or direct device connection) with UE-B. During the sidelink establishment process, UE-B can also obtain information such as the end-to-end total service latency (including image recognition latency and intermediate data transmission latency) and the computation time consumed by UE-A to calculate layers 1-4 of the Alexnet model. Since UE-B has already obtained the end-to-end total service latency and the computation time consumed by UE-A to calculate layers 1-4 of the Alexnet model, and UE-B knows its own computation time for calculating layers 5-15 of the Alexnet model, UE-B can determine the QoS parameters for the Uu interface (the interface between UE-B and NG-RAN) and the QoS parameters for the PC5 interface (the interface between UE-B and UE-A), while maintaining the end-to-end total service latency for performing image recognition in Figure 5 consistent with the end-to-end total service latency for performing image recognition in Figure 4.

[0122] Note: It is assumed that UE-A and UE-B have the same computing power, that is, the time used to calculate certain AlexNet model layers is the same for UE-A and UE-B. Otherwise, the data rate on the Uu interface and PC5 interface may change accordingly.

[0123] 4. UE-A sends the intermediate data (data obtained after calculating layers 1-4 of the Alexnet model) to UE-B via the sidelink, allowing UE-B to perform further calculations (i.e., calculate layers 5-15 of the Alexnet model). UE-B then sends the intermediate data calculated by UE-A (data obtained after calculating layers 1-4 of the Alexnet model) and the intermediate data calculated by UE-B (data obtained after calculating layers 5-15 of the Alexnet model) to the application server via the Uu interface. The specific model layers calculated by UE-A and UE-B are shown in Figure 5. Proximity-based workload offloading is achieved using direct device connection (i.e., sidelink). In this case, there is no need to increase the data rate on UE-A's Uu interface, while simultaneously offloading UE-A's computational load.

[0124] 5. UE-A continues to use the sidelink and the computing power of UE-B for image recognition, while the end-to-end service latency of image recognition remains unchanged.

Furthermore, the second terminal uses the IP address previously used by the first terminal to transmit computing task-related data, thereby ensuring that the IP address used by the second terminal to transmit computing task-related data before and after participating in the computing task remains unchanged, and the network can also identify the computing task-related data transmitted by the second terminal after participating in the computing task.

Specifically, the second terminal uses the address information of the first PDU session to transmit the computing task-related data, which can ensure that the address used by the second terminal when transmitting the computing task-related data before and after participating in the computing task remains unchanged, and the network can also identify the computing task-related data transmitted by the second terminal after participating in the computing task.

[0152] In some embodiments, the amount of computing tasks performed by the first terminal and the amount of computing tasks performed by the second terminal may be determined by the first terminal and indicated to the second terminal. Alternatively, the amount of computing tasks performed by the first terminal and the amount of computing tasks performed by the second terminal may be determined by negotiation between the first terminal and the second terminal.

[0153] In some embodiments, the first terminal sends the first information after a discovery process, that is, the first terminal may send the first information to the second terminal after discovering the second terminal. Specifically, the discovery process may be shown in FIG2 .

[0154] In some embodiments, the first terminal sends the first information during the process of establishing a sideline connection with the second terminal. Optionally, for example, the first information is carried by a direct communication request, that is, the first terminal can carry the first information in the direct communication request sent during the process of establishing the sideline connection with the second terminal.

[0155] In some embodiments, the first terminal sends the first information after establishing a sideline connection (also referred to as a PC5 connection) with the second terminal. Optionally, for example, the first information is carried by a PC5 user plane message. Specifically, the PC5 connection establishment process can be shown in Figure 2.

[0156] In some embodiments, each computing task of the first service is executed by a first model. Optionally, the first model is an Alexnet model, or the first model is another network model, which is not limited in this embodiment of the present application.

[0157] In some embodiments, the model information of the first model is obtained by the first terminal during a registration process. For example, the model information of the first model is obtained by the first terminal during a fifth generation system (5G system, 5GS) registration process. Specifically, the 5GS registration process may be as shown in FIG2 .

[0158] In some embodiments, the model information of the first model is pre-configured by the network device, or the model information of the first model is agreed upon by a protocol.

[0159] In some embodiments, the model information of the first model includes but is not limited to at least one of the following: model topology and parameter information of the first model, model segmentation point information of the first model, and the amount of intermediate data corresponding to the model segmentation points of the first model.

[0160] For example, the amount of intermediate data corresponding to the model segmentation points of the first model may be as shown in Table 1 above.

[0161] In some embodiments, the first terminal discovers the second terminal according to at least one of the following:

[0162] Whether the first model is supported, and whether proximity computing services are supported.

[0163] In some embodiments, the second information is carried by one of the following:

[0164] PDU session establishment request, PDU session modification request.

[0165] Specifically, the PDU session establishment process may be shown in FIG2 .

[0166] For example, the second terminal may send a PDU session establishment request to request the establishment of a new PDU session, which is recorded as a second PDU session. The address information of the second PDU session is the address information of the first PDU session. The second PDU session is used to transmit at least one of the following: data related to the computing task performed by the second terminal, and data related to the computing task performed by the first terminal obtained from the first terminal. The address information is, for example, an IP address.

[0167] For example, the second terminal may request to establish a new PDU session by sending a PDU session establishment request, which is recorded as a second PDU session. The second PDU session may be the same PDU session as the first PDU session, and the address information corresponding to the second PDU session is the address information of the first PDU session. The second PDU session is used to transmit at least one of the following: data related to the computing task performed by the second terminal, and data related to the computing task performed by the first terminal obtained from the first terminal. The address information is, for example, an IP address.

[0168] For another specific example, the second terminal may send a PDU session modification request to request modification of an existing PDU session, which is recorded as a third PDU session. The address information of the modified third PDU session is the address information of the first PDU session. The modified third PDU session is used to transmit at least one of the following: data related to a computing task performed by the second terminal, and data related to a computing task performed by the first terminal obtained from the first terminal. The address information is, for example, an IP address.

[0169] In some embodiments, when the second information is carried in a PDU session establishment request, the third information is carried in a PDU session establishment response; and / or, when the second information is carried in a PDU session modification request, the third information is carried in a PDU session modification response.

[0170] In some embodiments, the first terminal triggers the release of the first PDU session. That is, after the second terminal participates in the computing task, the first terminal can transmit data related to the computing task performed by the first terminal through the second terminal, and thus the first terminal can trigger the release of the first PDU session.

[0171] In some embodiments, the SMF entity triggers the release of the first PDU session. That is, after the second terminal participates in the computing task, the first terminal can transmit the computing task related data executed by the first terminal through the second terminal, and therefore, the SMF can trigger the release of the first PDU session.

[0172] Therefore, in an embodiment of the present application, the first terminal sends the first information, so that the second terminal can instruct to obtain the address information of the first PDU session based on the content contained in the first information, and then the second terminal can use the address information of the first PDU session to transmit at least one of the following: data related to the computing task performed by the second terminal, and data related to the computing task performed by the first terminal obtained from the first terminal. Specifically, the second terminal uses the address information of the first PDU session to transmit the computing task related data, which can ensure that the address information used by the second terminal when transmitting the computing task related data before and after participating in the computing task remains unchanged, and the network can also identify the computing task related data transmitted after the second terminal participates in the computing task. That is, when the first terminal accesses the network through the second terminal and the second terminal supports the proximity computing service, for the first business, the second terminal can share part of the computing task of the first terminal, and the second terminal can use the side link between the first terminal to realize the work task offloading based on the proximity service, thereby reducing the computing load of the first terminal and optimizing the computing and transmission efficiency of the first business.

[0177] In some embodiments, the first terminal may be a remote terminal, and the second terminal may be a relay terminal.

[0178] In some embodiments, before the second terminal executes the proximity computing service (i.e., before the second terminal participates in the computing task), the computing task executed by the first terminal and the computing task executed by the network constitute the first service. For example, as shown in FIG4 , the computing task executed by the first terminal is the computing task of layers 1-15 of the Alexnet model, and the computing task executed by the network (i.e., the application server) is the computing task of layers 16-24 of the Alexnet model, and the computing task of layers 1-24 of the Alexnet model constitutes the first task (i.e., the image recognition task).

[0189] Specifically, the SMF entity in S320 is the SMF entity serving the first PDU session.

[0190] In an embodiment of the present application, the second terminal may obtain the address information of the first PDU session through the second information indication, and further, the second terminal may use the address information of the first PDU session to transmit at least one of the following: data related to the computing task performed by the second terminal, and data related to the computing task performed by the first terminal obtained from the first terminal. Specifically, the second terminal uses the address information of the first PDU session to transmit the computing task-related data, which can ensure that the address information used by the second terminal when transmitting the computing task-related data before and after participating in the computing task remains unchanged, and the network can also identify the computing task-related data transmitted by the second terminal after participating in the computing task.

[0191] In some embodiments, the amount of computing tasks performed by the first terminal and the amount of computing tasks performed by the second terminal may be determined by the first terminal and indicated to the second terminal. Alternatively, the amount of computing tasks performed by the first terminal and the amount of computing tasks performed by the second terminal may be determined by negotiation between the first terminal and the second terminal.

[0192] In some embodiments, the second information is carried by one of the following:

[0193] PDU session establishment request, PDU session modification request.

[0194] Specifically, the PDU session establishment process may be shown in FIG2 .

[0195] For example, the second terminal can send a PDU session establishment request to request the establishment of a new PDU session, which is recorded as the second PDU session. The IP address of the second PDU session is the IP address corresponding to the first PDU session. The second PDU session is used to transmit at least one of the following: data related to the computing task performed by the second terminal, and data related to the computing task performed by the first terminal obtained from the first terminal.

[0196] For example, the second terminal can request to establish a new PDU session by sending a PDU session establishment request, which is recorded as the second PDU session. The second PDU session can be the same PDU session as the first PDU session, and the IP address corresponding to the second PDU session is the IP address corresponding to the first PDU session. The second PDU session is used to transmit at least one of the following: data related to the computing task performed by the second terminal, and data related to the computing task performed by the first terminal obtained from the first terminal.

[0197] Specifically, for example, the second terminal can send a PDU session modification request to request to modify an original PDU session, which is recorded as the third PDU session. The IP address corresponding to the modified third PDU session is the IP address corresponding to the first PDU session. The modified third PDU session is used to transmit at least one of the following: data related to the computing task performed by the second terminal, and data related to the computing task performed by the first terminal obtained from the first terminal.

[0199] In some embodiments, the first terminal triggers the release of the first PDU session. That is, after the second terminal participates in the computing task, the first terminal can transmit data related to the computing task performed by the first terminal through the second terminal, and thus the first terminal can trigger the release of the first PDU session.

[0200] In some embodiments, the SMF entity triggers the release of the first PDU session. That is, after the second terminal participates in the computing task, the first terminal can transmit the computing task related data executed by the first terminal through the second terminal, and therefore, the SMF can trigger the release of the first PDU session.

[0201] In some embodiments, before sending the second information, the second terminal may also receive the first information sent by the first terminal; wherein the first information includes at least one of the following: identification information of the first terminal, identification of the first PDU session, and first indication information; the first indication information is used to instruct the second terminal to perform proximity computing services.

[0203] In an embodiment of the present application, the first indication information is used to instruct the second terminal to perform a proximity computing service, and then the second terminal can trigger a PDU session establishment or modification process and obtain the IP address previously used by the first terminal (i.e., the IP address corresponding to the first PDU session). Furthermore, the second terminal uses the IP address previously used by the first terminal to transmit computing task-related data, thereby ensuring that the IP address used by the second terminal to transmit computing task-related data before and after participating in the computing task remains unchanged, and the network can also identify the computing task-related data transmitted by the second terminal after participating in the computing task.

[0204] In some embodiments, the first terminal sends the first information after a discovery process, that is, the first terminal may send the first information to the second terminal after discovering the second terminal. Specifically, the discovery process may be shown in FIG2 .

[0205] In some embodiments, the first terminal sends the first information during the process of establishing a sideline connection with the second terminal. Optionally, for example, the first information is carried by a direct communication request, that is, the first terminal can carry the first information in the direct communication request sent during the process of establishing the sideline connection with the second terminal.

[0206] In some embodiments, the first terminal sends the first information after establishing a sideline connection (also referred to as a PC5 connection) with the second terminal. Optionally, for example, the first information is carried by a PC5 user plane message. Specifically, the PC5 connection establishment process can be shown in Figure 2.

[0207] In some embodiments, each computing task of the first service is executed by a first model. Optionally, the first model is an Alexnet model, or the first model is another network model, which is not limited in this embodiment of the present application.

[0208] In some embodiments, the model information of the first model is obtained by the first terminal during a registration process. For example, the model information of the first model is obtained by the first terminal during a fifth generation system (5G system, 5GS) registration process. Specifically, the 5GS registration process may be as shown in FIG2 .

[0209] In some embodiments, the model information of the first model is pre-configured by the network device, or the model information of the first model is agreed upon by a protocol.

[0210] In some embodiments, the model information of the first model includes but is not limited to at least one of the following: model topology and parameter information of the first model, model segmentation point information of the first model, and the amount of intermediate data corresponding to the model segmentation points of the first model.

[0211] For example, the amount of intermediate data corresponding to the model segmentation points of the first model may be as shown in Table 1 above.

[0212] Therefore, in an embodiment of the present application, the first terminal sends the first information, so that the second terminal can instruct to obtain the address information of the first PDU session based on the content contained in the first information, and then the second terminal can use the address information of the first PDU session to transmit at least one of the following: data related to the computing task performed by the second terminal, and data related to the computing task performed by the first terminal obtained from the first terminal. Specifically, the second terminal uses the address information of the first PDU session to transmit the computing task related data, which can ensure that the address used by the second terminal when transmitting the computing task related data before and after participating in the computing task remains unchanged, and the network can also identify the computing task related data transmitted after the second terminal participates in the computing task. That is, when the first terminal accesses the network through the second terminal and the second terminal supports the proximity computing service, for the first business, the second terminal can share part of the computing task of the first terminal, and the second terminal can use the side link between the first terminal to realize the work task offloading based on the proximity service, thereby reducing the computing load of the first terminal and optimizing the computing and transmission efficiency of the first business.

[0213] The technical solution of this application is described in detail below through a specific embodiment.

[0214] In Example 1, assuming the first terminal is UE1, the second terminal is UE2, the first PDU session is PDU session 1, and the address information of the PDU session is an IP address. As shown in Figure 9, it can include three parts: the first part: UE1 and UE2 establish a PC5 connection, which can be implemented through S1-1 to S1-3; the second part: UE2 (i.e., the relay UE) establishes a PDU session, which can be implemented through S2-1 to S2-5; and the third part: UE1 or the SMF entity triggers the release of UE1's PDU session 1.

[0215] As shown in FIG9 , before the first part, a PDU session 1 is established between UE1 and the network, and UE1 can use PDU session 1 to transmit computing task related data.

[0216] S1-1, UE1 sends a direct communication request to UE2.

[0217] S1-2, a secure link is established between UE1 and UE2.

[0218] S1-3, UE2 sends a direct communication response to UE1.

[0219] Optionally, UE1 may inform UE2 of at least one of the following parameters through a direct communication request:

[0220] UE1 identity (Identity, ID), the identity of UE1's PDU session 1, the first indication information.

[0221] Optionally, UE1 may inform UE2 of at least one of the following parameters through a PC5 user plane message:

[0222] UE1 identity (Identity, ID), the identity of UE1's PDU session 1, the first indication information.

[0223] Among them, UE1ID refers to the ID used by UE1 in the core network, such as SUPI, 5G-GUTI, which can be identified by the core network elements; or UE1ID refers to the layer 2 ID of UE1, and then UE2 determines the ID used by UE1 in the core network based on the layer 2 ID of UE1. The identifier of UE1's PDU session 1: refers to the PDU session identifier currently used by UE1 to transmit data for the first service. The first indication information: is used to instruct UE2 to perform "proximity computing service", so that UE2 can trigger the establishment of the second part of the PDU session and obtain the IP address previously used by UE1.

[0224] It should be noted that, in the first part, UE1 may have multiple PDU sessions. The PDU session mentioned here is the PDU session serving the first business data transmission, and other PDU sessions may not be affected.

[0225] Optionally, in the direct communication request or PC5 user plane message in the first part, UE1 may send at least one of the following parameters to UE2: information about the computing task performed by UE1, information about the computing task performed by UE2, the computing time of the computing task performed by UE1, and the total service time (including the computing time of the computing task performed by UE1, the computing time of the computing task performed by UE2, the time for transmitting data related to the computing task performed by UE1 and data related to the computing task performed by UE2, and the computing time of the computing task performed by the network). Thus, UE2 can determine the QoS parameters of the PC5 interface between UE2 and UE1, and the QoS parameters of the Uu interface between UE2 and the network device. Furthermore, UE2 can receive data related to the computing task performed by UE1 based on the QoS parameters of the PC5 interface; and UE2 can transmit data related to the computing task performed by UE1 and data related to the computing task performed by UE2 to the network based on the QoS parameters of the Uu interface.

[0226] S2-1, UE2 sends a PDU session establishment request to the SMF entity, wherein the PDU session establishment request includes at least one of the following: UE1ID, the identifier of UE1's PDU session 1, and second indication information. The second indication information is used to indicate the acquisition of the IP address of PDU session 1, and / or the second indication information is used to indicate the selection of the SMF entity serving PDU session 1. In addition, optionally, the PDU session requested by UE2 can carry the PDU session 2 identifier separately, and the identifier of UE1's PDU session 1 can be used as the identifier for UE2 to establish the PDU session.

[0227] S2-2, PDU session establishment / modification based on N4 interface is performed between SMF entity and UPF entity.

[0228] S2-3, the SMF entity sends an N1N2 message to the AMF entity.

[0229] S2-4, the AMF entity sends an N2PDU session request to the Radio Access Network (RAN) device.

[0230] S2-5, the RAN device and UE2 execute access network (AN) related resource establishment (also carrying a downlink PDU session establishment response, including the IP address corresponding to UE1's PDU session 1).

[0231] In the second part, after receiving the PDU session establishment request, the SMF entity assigns the IP address identified by UE1's PDU session 1 to UE2 and continues to execute other process steps for establishing the PDU session.

[0232] After the second part, UE2 can obtain the data related to the computing task performed by UE1 through the PC5 link, and UE2 can use PDU session 2 to transmit the data related to the computing task performed by UE1 and the data related to the computing task performed by UE2.

[0233] In the third part, since the IP address corresponding to UE1's PDU session 1 has been used by UE2, UE1's PDU session 1 needs to be released. The release can be triggered by the SMF entity or UE1.

[0234] FIG10 is a schematic flow chart of a wireless communication method 400 according to an embodiment of the present application, in which a first terminal uses a PDU session established between a second terminal and a network to transmit data related to the first terminal. Specifically, as shown in FIG10 , the wireless communication method 400 may include at least part of the following contents:

[0235] S410, the first terminal sends fourth information; wherein the fourth information includes at least one of the following: information about the first computing task, information about the second computing task, computing time of the first computing task, and total time of the first service; wherein the first computing task is executed by the first terminal, the second computing task is executed by the second terminal, and the first computing task, the second computing task, and computing tasks executed by the network constitute the first service; wherein the total time of the first service includes computing time of the first computing task, time for transmitting data related to the first computing task, computing time of the second computing task, time for transmitting data related to the second computing task, and computing time of computing tasks executed by the network;

[0236] S420: The second terminal receives the fourth information.

[0237] In an embodiment of the present application, the second terminal can support proximity computing services, that is, the second terminal can not only provide relay communication services, but also provide computing power to provide computing services for a certain task and send the calculation results to the application server.

[0238] In some embodiments, the first terminal may be a remote terminal, and the second terminal may be a relay terminal.

[0239] In some embodiments, before the second terminal executes the proximity computing service (i.e., before the second terminal participates in the computing task), the computing task executed by the first terminal and the computing task executed by the network constitute the first service. For example, as shown in FIG4 , the computing task executed by the first terminal is the computing task of layers 1-15 of the Alexnet model, and the computing task executed by the network (i.e., the application server) is the computing task of layers 16-24 of the Alexnet model, and the computing task of layers 1-24 of the Alexnet model constitutes the first task (i.e., the image recognition task).

[0240] In some embodiments, after the second terminal executes the proximity computing service (i.e., after the second terminal participates in the computing task), the computing task executed by the first terminal, the computing task executed by the second terminal, and the computing task executed by the network constitute the first service. For example, as shown in FIG5 , the computing task executed by the first terminal is the computing task of layers 1-4 of the Alexnet model, the computing task executed by the second terminal is the computing task of layers 5-15 of the Alexnet model, the computing task executed by the network (i.e., the application server) is the computing task of layers 16-24 of the Alexnet model, and the computing task of layers 1-24 of the Alexnet model constitutes the first task (i.e., the image recognition task).

[0241] In some embodiments, the first service may be an image recognition task, a measurement task, a positioning task, etc., which is not limited in this embodiment of the present application.

[0242] It should be noted that the QoS on the PC5 interface and the Uu interface is determined by the relay terminal (i.e., the second terminal). Generally, since the relay terminal (i.e., the second terminal) only provides communication services, that is, forwarding the data sent by the remote terminal (i.e., the first terminal) to the fifth generation system (5G System, 5GS), the QoS parameters of the PC5 interface and the Uu interface are the same.

[0243] However, when the relay terminal (i.e., the second terminal) provides not only communication services but also computing services (also known as "proximal computing services"), it is necessary to consider the QoS parameter values ​​on different interfaces from the perspective of end-to-end services, because at this time, the end-to-end service time is determined by the task computing time + communication time.

[0244] In an embodiment of the present application, when a first terminal accesses a network through a second terminal and the second terminal supports proximity computing services, the second terminal can determine the QoS parameters of the PC5 interface between the second terminal and the first terminal, as well as the QoS parameters of the Uu interface between the second terminal and the network device, based on information about the computing task performed by the first terminal, the computing time of the computing task performed by the first terminal, information about the computing task performed by the second terminal, the computing time of the computing task performed by the second terminal, and the total time of the first service (including computing and transmission time). Furthermore, the second terminal can receive data related to the computing task performed by the first terminal based on the QoS parameters of the PC5 interface; and the second terminal can transmit data related to the computing task performed by the first terminal and data related to the computing task performed by the second terminal to the network based on the QoS parameters of the Uu interface.

[0245] In some embodiments, the IP address used by the second terminal when transmitting the first computing task-related data and / or the second computing task-related data is the IP address of the first terminal. Specifically, the first terminal can send the first computing task-related data to the second terminal via the PC5 interface. After the second terminal executes the second computing task, the second terminal sends the first computing task-related data and / or the second computing task-related data to the network. Moreover, the IP address used by the second terminal when transmitting the first computing task-related data and / or the second computing task-related data is the IP address of the first terminal.

[0246] It should be noted that the IP address of the first terminal may be: the IP address corresponding to the PDU session that the first terminal requests to establish before the second terminal participates in the computing task and is used to transmit data related to the computing task performed by the first terminal.

[0247] Specifically, the second terminal uses the IP address previously used by the first terminal to transmit computing task-related data, thereby ensuring that the IP address used by the second terminal to transmit computing task-related data before and after participating in the computing task remains unchanged, and the network can also identify the computing task-related data transmitted by the second terminal after participating in the computing task.

[0248] In some embodiments, the second terminal sends fifth information; wherein the fifth information is used to request the IP address of the first terminal, and / or the fifth information is used to indicate that the second terminal will perform a proximity computing service.

[0249] For example, the second terminal sends the fifth information to the SMF entity, and the SMF can allocate the IP address of the first terminal to the second terminal based on the fifth information.

[0250] In some embodiments, the fifth information includes at least one of the following: identification information of the first terminal, and PDU session information used by the first terminal to transmit data related to the computing task it performs. The identification information of the first terminal includes at least an identification used by the first terminal in the core network.

[0251] It should be noted that the IP address of the first terminal is the IP address corresponding to the PDU session used by the first terminal to transmit data related to the computing task it performs. After the SMF entity learns the PDU session information used by the first terminal to transmit data related to the computing task it performs, it can know the IP address of the first terminal. Thus, the SMF can assign the IP address of the first terminal to the second terminal.

[0252] In some embodiments, the content included in the fifth information is obtained by the second terminal in a discovery process, or the content included in the fifth information is obtained by the second terminal in a process of establishing a sideline connection with the first terminal.

[0253] In some embodiments, the fifth information is sent by the second terminal in the process of requesting to establish a target PDU session;

[0254] The target PDU session is used to transmit data related to the first computing task and / or data related to the second computing task.

[0255] In some embodiments, the target PDU session may be a PDU session requested by the first terminal to be established for transmitting data related to the computing task performed by it, or the target PDU session may be a PDU session different from the PDU session requested by the first terminal to be established.

[0256] In some embodiments, the fifth information is carried by one of the following:

[0257] PDU session establishment request, PDU session modification request.

[0258] Specifically, the PDU session establishment process may be shown in FIG2 .

[0259] For example, the second terminal can request to establish a new PDU session, namely, a target PDU session, by sending a PDU session establishment request. The IP address corresponding to the target PDU session is the IP address of the first terminal. The target PDU session is used to transmit at least one of the following: data related to the computing task performed by the second terminal, and data related to the computing task performed by the first terminal obtained from the first terminal.

[0260] Specifically, for example, the second terminal can request to modify an original PDU session by sending a PDU session modification request. The modified PDU session is the target PDU session. The IP address corresponding to the target PDU session is the IP address of the first terminal. The target PDU session is used to transmit at least one of the following: data related to the computing task performed by the second terminal, and data related to the computing task performed by the first terminal obtained from the first terminal.

[0261] In some embodiments, each computing task of the first service is executed by a first model. Optionally, the first model is an Alexnet model, or the first model is another network model, which is not limited in this embodiment of the present application.

[0262] In some embodiments, the fourth information further includes at least one of the following:

[0263] Information about the first model, at least one model segmentation point of the first model and information about the corresponding intermediate data volume.

[0264] In some embodiments, the model information of the first model is obtained by the second terminal during a registration process. For example, the model information of the first model is obtained by the first terminal during a fifth generation system (5G system, 5GS) registration process, and the 5GS registration process may be as shown in FIG2 .

[0265] In some embodiments, the model information of the first model is pre-configured by the network device, or the model information of the first model is agreed upon by the protocol, or the model information of the first model is configured or indicated by the first terminal.

[0266] In some embodiments, the model information of the first model includes but is not limited to at least one of the following: model topology and parameter information of the first model, model segmentation point information of the first model, and the amount of intermediate data corresponding to the model segmentation points of the first model.

[0267] In some embodiments, the second terminal determines, based on the fourth information, quality of service (QoS) parameters of a PC5 interface between the second terminal and the first terminal, and QoS parameters of a Uu interface between the second terminal and the network device.

[0268] In some embodiments, the second terminal determines the QoS parameters of the PC5 interface between the second terminal and the first terminal, and the QoS parameters of the Uu interface between the second terminal and the network device based on the fourth information, the calculation time of the second computing task, at least one model segmentation point of the first model and the corresponding intermediate data volume information.

[0269] In some embodiments, the first terminal sends the fourth information after the discovery process. In other words, the second terminal receives the fourth information after the discovery process. Specifically, the discovery process may be as shown in FIG2 .

[0270] In some embodiments, the first terminal sends the fourth information during the process of establishing a sideline connection with the second terminal. In other words, the second terminal receives the fourth information during the process of establishing a sideline connection (i.e., a PC5 connection) with the first terminal. Specifically, the PC5 connection establishment process may be shown in FIG2 .

[0271] In some embodiments, the first terminal sends the fourth information after establishing a sideline connection (i.e., a PC5 connection) with the second terminal. In other words, the second terminal receives the fourth information after establishing a sideline connection with the first terminal. Specifically, the PC5 connection establishment process may be shown in FIG2 .

[0272] In some embodiments, the first terminal discovers the second terminal according to at least one of the following:

[0273] Whether the first model is supported, and whether proximity computing services are supported.

[0274] Therefore, in an embodiment of the present application, when the first terminal accesses the network through the second terminal and the second terminal supports proximity computing services, the second terminal can determine the QoS parameters of the PC5 interface between the second terminal and the first terminal, and the QoS parameters of the Uu interface between the second terminal and the network device based on the information of the computing task performed by the first terminal, the computing time of the computing task performed by the first terminal, the information of the computing task performed by the second terminal, the computing time of the computing task performed by the second terminal, and the total time of the first service (including computing and transmission time). Further, the second terminal can receive data related to the computing task performed by the first terminal based on the QoS parameters of the PC5 interface; and the second terminal can transmit data related to the computing task performed by the first terminal and data related to the computing task performed by the second terminal to the network based on the QoS parameters of the Uu interface. That is, when the first terminal accesses the network through the second terminal and the second terminal supports proximity computing services, for the first service, the second terminal can share part of the computing task of the first terminal, and the second terminal can use the side link between the first terminal and the first terminal to achieve work task offloading based on proximity services, thereby reducing the computing load of the first terminal and optimizing the computing and transmission efficiency of the first service.
